Description

The present invention is an incineration system that significantly improves reaction efficiency by connecting and supporting large SCR cartridges in one row (vertical) and two columns (horizontal) by a connecting member, which are hung on a support frame fixed to the inner wall of a housing. and a hanging support structure between a large SCR cartridge integrated with a dry reaction dust collector of a combustion furnace and a support frame.

In general, various harmful substances such as NOx, SOx, HCl, dioxins, and fly ash are generated in exhaust gases that are burned and discharged from incinerators and combustion furnaces.

Before the exhaust gas containing harmful substances is released into the atmosphere, the harmful substances are removed through air prevention equipment before being released into the atmosphere, and in this process, various harmful substances are removed. Atmospheric control equipment, which is equipment for removing hazardous substances, will be installed depending on the type of hazardous substances.

As a conventional dust collector provided for removing the harmful substances, one known in Patent Document 1 has been proposed.

As shown in FIG. 19, the dust collector 70 of Patent Document 1 includes a rectangular casing 74, a casing cover 75 and a hopper 76 installed at the upper and lower ends of the casing 74, and a hopper 76 arranged vertically inside the casing 74. It includes a mounted SCR cartridge 73, an air nozzle 77, and a back filter 78.

The SCR cartridge 73 is panel-shaped, and contains a pellet-shaped catalyst that reacts at low temperatures (145 to 180° C.). Selective Catalytic Reduction (SCR) is a technology that removes nitrogen oxides (NOx) emitted from combustion of fossil fuels and waste. Ammonia gas can be recovered by selectively using methods such as reusing the reacted and unreacted ammonia gas, or adding ammonia water as an SCR catalyst into the incoming exhaust gas to supply the necessary reaction chemicals. It is a catalyst that reacts (NH3) with NOx and reduces it to N2 and H2O.

The chamber between the casing cover 75 and the SCR cartridge 70 is a clean zone 71.

The clean zone 71 is a chamber in which unpurified exhaust gas enters the hopper 76 and purified gas that has passed through the back filter 78 and the SCR cartridge 73 is collected.

Further, the SCR cartridge 73 is placed on a support frame 72 which is an L-shaped steel section fixed to the inner wall 74a of the housing 74.

Typically, the SCR cartridge 73 includes a small cartridge of about 80 kg and a large cartridge of about 250 to 350 kg.

Four small cartridges are placed on a rice-shaped support frame 72 installed in one chamber, but if there are many chambers depending on the site, the small cartridges may be arranged in a grid pattern along the horizontal or vertical direction. will be done.

That is, a plurality or more small cartridges are arranged in one chamber both horizontally and vertically.

On the other hand, two large cartridges are placed in one chamber on a Japanese-shaped support frame 72, but if there are many chambers depending on the site, the large cartridges are arranged horizontally in a ladder shape. .

That is, a plurality or more large cartridges are arranged in one chamber in the horizontal direction, and only one in the longitudinal direction.

Therefore, there are multiple or more small SCR cartridges and large SCR cartridges in the horizontal direction, but multiple or more small cartridges and only one large cartridge in the vertical direction. It is classified.

Such a conventional SCR cartridge 73 is placed on the support frame 72 by its own weight, and when it is moved and shaken by the gas that has passed through the back filter 78, the internal catalyst is biased to one side and reacts with the catalyst. The unused gas directly enters the clean zone 71, lowering the reaction efficiency.

In addition, unreacted gas escapes into the gap between the SCR cartridge 72 and the support frame 72 due to manufacturing errors in the SCR cartridge 73, thermal deformation (distortion) during use, vibration during operation, and the like.

Therefore, gas that has not passed through the SCR cartridge 73 directly enters the clean zone 71, significantly reducing reaction efficiency.

Korean Registered Patent Publication No. 10-0769667

The present invention was devised in order to solve the above-mentioned problems, and the present invention is designed to connect and support a plurality of large SCR cartridges by a connecting member, which are suspended from a support frame fixed to the inner wall of a housing. The objective is to provide a suspended support structure between a large SCR cartridge and a support frame with an integrated dry reaction precipitator for an incinerator and combustion furnace with significantly improved efficiency.

In order to achieve the above-mentioned purpose, the hanging support structure between the large SCR cartridge integrated with the dry reaction dust collector of the incinerator and combustion furnace and the support frame of the present invention is provided in the housing between the casing cover and the back filter. a support frame fixed to a wall; a large number of panel-shaped small SCR cartridges arranged horizontally along the left-right (horizontal) and front-back (vertical) directions on the upper surface of the support frame; and the small SCR cartridge. and a connecting member that connects and supports the support frame to the support frame, the support frame includes front and rear left and right frame bars fixed in a band shape along the periphery of the inner wall, and a front and rear left and right frame bar fixed to the front and rear left and right frame bars in a cross shape. The small SCR cartridge includes a vertical crossbar and a horizontal crossbar, the lower side of the edge of the small SCR cartridge is placed on the upper surface of the support frame and is supported at the bottom, and the coupling members are fixed to the upper surface of the support frame at predetermined intervals. and a coupling part that is coupled to the coupling lug and pressurizes and supports the small SCR cartridge on the support frame.

According to the present invention, there are the following effects.

Since the wings installed around the periphery of the large SCR cartridge body can be hung on the support frame, it is difficult to improve conventional facilities by using the upper part of the back filter, due to investment costs and narrow space. If ground space is limited, a large SCR cartridge is suitable. In addition, since it is a large-scale production, it is also advantageous for reducing manufacturing labor and material costs.In contrast to the large number of sealing packings required for small SCR cartridges, the catalytic reaction efficiency is high even with a small-area sealed structure, so the design cost is reduced. can also save money.

In addition, by constructing a support frame made of U-shaped shaped steel in the form of a concave groove, and by fastening bolts to female screws fixed inside this support frame, the pressure plate can be easily pressurized and large SCR cartridges can be mounted. It is possible to increase the bonding strength.

On the other hand, the connection is completed by inserting the split pin into the connection hole of the connection lug while the pressure plate is inserted into the connection lug fixed inside the support frame, so many pressure plates are evenly pressurized and a large SCR is assembled. Many of the cartridges now remain well leveled.

Furthermore, the pair of pins of the split pin widen from each other toward the tip, and the top surface of the pair of pins is an inclined surface that becomes thinner toward the tip, so that when the split pin is inserted into the coupling hole, The more the inclined surface is inserted, the more pressure is applied to the coupling hole, making it difficult for the tape to come out, and the more the inclined surface is inserted, the more the sealing efficiency due to pressure between the support frame and the large SCR cartridge is significantly improved due to the wedge effect.

In addition, packing is further installed between the vertical bar of the support frame and the wings of the large SCR cartridge, further improving the sealing efficiency between the support frame and the large SCR cartridge.

Further, by further fixing the pressure plate supporting pieces facing the coupling lugs to the outer contours of the front, rear, left and right frame bars, it is possible to form a uniform pressure plate as a whole.

1 to 3 consist of a dust collector module in which four unit dust collectors are arranged in the 1st, 2nd, 3rd, and 4th quadrants.

Therefore, the following description will be made based on only the case where the dust collector is located in one quadrant or four quadrants.

As shown in FIGS. 1 to 3, the incinerator and combustion furnace dust collector 100 according to the present embodiment includes a rectangular housing 110, a casing cover 130 and a hopper 150 installed at the upper and lower ends of the housing 110, and a housing. a plurality of large SCR cartridges 200 mounted in the upper part of the interior of the housing 110; an air nozzle 170; a back filter 190; a support frame 300 on which the plurality of large SCR cartridges 200 are placed and supported while being fixed to the inner wall of the housing 110 , a coupling member 500 for coupling and supporting the large SCR cartridge 200 to the support frame 300.

Further, the casing cover 130 is fixed to the upper side of the housing 110.

Further, a clean zone 140 is formed in the chamber between the casing cover 130 and the large SCR cartridge 200.

As shown in FIGS. 4 to 7, the large SCR cartridge 200 includes a large SCR cartridge main body 210 made of an iron plate made of stainless steel, and a wing part 220 fixed along the side surface of the large SCR cartridge main body 210. .

The large SCR cartridge main body 210 is a panel-shaped square tube, and a catalyst is placed inside thereof.

The wing portion 220 is supported by being hung on the upper surface of the support frame 300.

The wing section 220 includes front and rear wing sections 221 formed along the front and rear sides, and left and right wing sections 223 formed along the left and right side surfaces.

Further, as shown in FIGS. 10, 12, and 13, the front, rear, left, and right wings 221, 223 have one end extending along the periphery of the side plate 215, and the front, rear, left, and right horizontal wings 221a, 223a. It includes front, rear, left and right vertical wings 221b and 223b extending downward from the other end.

The insides of the front, rear, left, and right horizontal wings 221a, 223a and the front, rear, left, and right vertical wings 221b, 223b function as grooves into which a packing portion 600, which will be described later, is inserted and attached.

Of course, without the packing 600, the large SCR cartridge main body 200 would be supported by the front, rear, left and right horizontal wings 221a, 223a being hung on the support frame 300.

Since such a wing part 220 only needs to be hung on the support frame, when improving conventional facilities using the upper part of the back filter, if the ground space is restricted due to investment cost and narrow site, a large SCR cartridge 200 is suitable.

In addition, since it is a large-scale production, it is also advantageous for reducing manufacturing labor and material costs.In contrast to the large number of sealing packings required for small SCR cartridges, the catalytic reaction efficiency is high even with a small-area sealed structure, so the design cost is reduced. You can also save money.

The large SCR cartridge main body 210 is composed of upper and lower perforated plates 211, 213 and side plates 215, which form the outer shape. The side plate 215 is a steel section having a U-shaped cross section.

The upper and lower perforated plates 211 and 213 and the side plate 215 are connected by riveting.

The pore distribution positions of the upper and lower perforated plates 221 and 213 may be uniformly distributed over the entire upper and lower sides according to the site conditions and minimizing the non-reactive area, or the pores may be distributed toward the center of the upper perforated plate 211, and the pores may be distributed toward the center of the upper perforated plate 211, and the pores of the lower perforated plate are For 213, those distributed on the left and right sides or the opposite positions are used.

Two lifting lugs 240 are fixed to each of the upper and lower surfaces of the upper perforated plate 211.

The reason why the lifting lugs 240 are placed one above the other is to fill the inside of the lifting lugs 240 with catalyst in an upright state.

In particular, the large SCR cartridge main body 210 consists of a single housing whose interior is divided into many parts.

For such internal multi-division, a U-shaped steel section 250 with dividing ribs, such as a side plate 215, is further fixed inside the upper and lower perforated plates 211 and 213, as shown in FIGS. 6 and 7. .

The split rib-like U-shaped steel section 250 serves as a reinforcing material to suppress tensile deformation of the upper and lower perforated plates 211 and 213 and torsional deformation of the large SCR cartridge main body 210 during lifting.

The split rib-like U-shaped steel section 250 divides the cylinder in which the catalyst is placed into front, rear, left, and right sections, so as shown in FIGS. 5 and 6, there are An opening 231 is formed, and the opening 231 is opened and closed by a catalyst filling cover plate 233.

The catalyst filling cover plate 233 is fastened to the front and rear surfaces of the side plate 215 using countersunk bolts.

At this time, the lower ends of the front and rear vertical wings 221b with openings 231 as shown in FIG. 10 are arranged above the lower ends of the left and right vertical wings 223b in FIGS. 12 and 13 (see FIG. This is to prevent the vertical wings 221b from hiding the opening 231, thereby making it easier to insert and remove the catalyst and to attach and detach the cover plate 223.

Two such large SCR cartridges 200 are placed on the support frame 300 shown in FIG. 8.

Of course, the support frame 300 can be expanded left and right as desired.

For example, as shown in FIG. 3, if the large SCR cartridges 200 are arranged in one row and four columns, the support frame 300 will also be further extended laterally.

The support frame 300 is a steel section with a U-shaped cross section, and is fixed to the inner wall of the housing 110.

That is, as shown in FIG. 8, the support frame 300 includes front and rear left and right frame bars 310, 320, 330, and 340 that are fixed in a band shape along the periphery of the inner wall, and is fixed inside the front and rear frame bars 310 and 320. It includes a vertical crossbar 350.

In the space of the support frame 300 arranged in this manner, two large SCR cartridge bodies 210 shown by dotted lines are placed and hung on the upper surface of the support frame 300 to form a suspended support type structure.

Here, as shown in FIGS. 1 and 2, the support frame 300 is supported by the support section for the back filter 190.

As shown in FIGS. 10, 12, and 13, the support frame 300 includes a first vertical bar 301, a second vertical bar 303, and a connecting bar 305 that connects the lower sides of the first and second vertical bars 301 and 303. It is a section steel with a concave cross section.

The first vertical bars 301 of the front, rear, left, and right frame bars 310, 320, 330, and 340 are fixed to the inner wall of the housing 110, as shown in FIGS. 10 and 12.

The wing parts 220 are hung on the second vertical bars of the front, rear, left and right frame bars 310, 320, 330, 340 and the first and second vertical bars 301, 303 of the vertical cross bar 350 to be supported.

A coupling member 500 according to a modified example includes a female thread 510 inserted into the bottom of the connection bar 305 and a pressure plate 530a or 530b placed on the large SCR cartridge 200, as shown in FIGS. 10, 12, and 13. , a bolt 550 is fastened to the female thread 510 to pressurize and support the large SCR cartridge 200 onto the support frame 300 so that the pressure plate 530a or 530b may include a bolt 550.

Bolt 550 is an eye bolt.

The pressure plate 530a or 530b is applied to the first pressure plate 530a, which is applied to and supports the large SCR cartridge 200 between the vertical cross bars 350 under pressure, as shown in FIG. It includes a second pressure plate 530b that presses and supports the large SCR cartridge 200.

The first pressure plate 530a is a first horizontal plate that presses the left and right large SCR cartridges 200 with the same pressure.

The second pressure plate 530b includes a second horizontal plate 531b and a second vertical plate 533b bent toward the connection bar 305 from the second horizontal plate 531b, as shown in FIGS. 10 and 11.

The second horizontal plate 531b is placed on the upper surface of the U-shaped steel side plate 215 and the front and rear wings 221, and has an insertion hole into which a bolt 550 is inserted.

The second horizontal plate 533b is lowered to the inside of the support frame 300, and when its tip hits the bottom of the connection bar 305, it is no longer fastened.

In addition, a packing 600 is further installed between the first and second vertical bars 301 and 303 and the wing portion 220, and the reaction efficiency is increased by preventing unreacted gas from being extracted into the gap between the packings 600.

Another variant coupling member 500' is shown in FIGS. 15-17.

The coupling member 500' includes coupling lugs 510' welded and fixed to the upper surface of the support frame 300 at predetermined intervals, a pressure plate 530' placed on the upper surface of the large SCR cartridge 200 on the coupling lugs 510', and It includes a split pin 540' that is inserted into the coupling hole 511' of the lug 510' and couples the pressure plate 530' while pressurizing it.

The pressure plate 530' is made of a rectangular plate as shown in FIG.

As shown in FIG. 18, the split pin 540' has a head 541' that is bent into an almost elliptical shape, and a pair of pins 543' that extend from both sides of the head 541' so that they become wider toward the tip. include.

In particular, the split pin 540' is a pin formed by bending a band-shaped plate.

Further, the upper surface of the pair of pins 543' is formed by an inclined surface 545' whose thickness becomes gradually thinner toward the tip.

As shown in FIG. 17, such an inclined surface 545' forms a wedge shape when viewed from the front.

Therefore, when the pair of pins 543' of the split pin 540' are shortened and then inserted into the coupling hole 511' and driven in, the pressing plate 530' is pushed down by the inclined surface 545' while moving forward, so that the coupling force is very excellent. In particular, the contact sealing force between the large SCR cartridge 200 and the support frame 300 can be improved, and the reaction efficiency can be significantly increased.

Further, by inserting the pair of pins 543' which are spread out in a V-shape into the coupling hole 511', a repulsive force that tends to spread acts, thereby further preventing arbitrary detachment.

The above-described pressure plate 530' is configured to connect the large SCR cartridge 200 with the vertical crossbar 350 of FIG. 14 sandwiched therebetween.

On the other hand, a coupling member 500' of another modification shown in FIGS. 15 and 16 has a structure for coupling between the large SCR cartridge 200 and the front, rear, left, and right frame bars 310, 320, 330, and 340.

Therefore, in the other modification of the coupling member 500' shown in FIGS. 15 and 16, as shown in FIG. There is a difference in what is being done.

In other words, the coupling member 500' of the other modified example shown in FIGS. A pressure plate supporting piece 550' facing the outer shell of the coupling lug 510', a pressure plate 530' inserted into the coupling lug 510' and placed on the upper surface of the large SCR cartridge 200 and the pressure plate supporting piece 550', are coupled. The split pin 540' is inserted into the coupling hole 511' of the lug 510'.

Therefore, when the split pin 540' is coupled, the pressure plate 530' evenly presses the upper surfaces of the large SCR cartridge 200 and the pressure plate supporting piece 550', thereby improving the coupling force of the large SCR cartridge 200.
