Described waveform separator exists spacing and parallel waveform sheet metal to form by polylith, and adjacent waveform sheet metal spacing is 10mm.
The invention has the advantages that this apparatus structure is succinct, be convenient to make, install and maintenance, can guarantee simultaneously the good of water circulation operating mode, avoid circulation resistance excessive, and this device can effectively carry out carbonated drink separation, reduce the superheater tubes burst probability, satisfied the reliability of boiler operatiopn and user's demand.
Description of drawings
The below is briefly described the content of every width accompanying drawing expression in specification of the present invention and the mark in figure:
Fig. 1 is the water separator structural representation;
Mark in above-mentioned figure is: 1, drum body; 2, tedge; 3, arc buffering cover; 4, baffle plate; 5, steam fairlead; 6, waveform separator; 7, waveform impact-absorbing shell; 9, continuous blowdown pipe; 10, feed pipe; 11, chemical feed pipe; 12, water surface blow-off pipe.
The specific embodiment
Referring to Fig. 1 as can be known, moisture separation device is arranged in cement kiln kiln hood waste heat boiler drum, gas through drum output is carried out the device of dehumidification treatments, drum mainly comprises drum body 1, input obliquely from the side the tedge 2 of drum steam, be arranged at drum body 1 top and upwards export the steam fairlead 5 of steam, and the feed pipe 10, continuous blowdown pipe 9, chemical feed pipe 11 and the water surface blow-off pipe 12 that stretch into drum.
Moisture separation device of the present invention mainly adopts the mode of twice separation, wherein first separation is arranged on the drum body interior tedge 2 mouth of pipe places of input steam water interface, secondary separation device is arranged at steam fairlead 3 mouth of pipe places of the interior output gas of drum body 1, and such combination can be played better separating effect.
The first separation device comprises arc buffering cover 3 and baffle plate 4, its arc buffering cover 3 is located at tedge 2 mouth of pipe places, this arc buffering cover 3 slot opening 25m, each notch spacing 35mm, when entering drum by the next steam water interface of evaporating heating surface, with very large kinetic energy, if this element is not installed, steam water interface will be flushed on bubble (drum) wall or the water surface, cause water-drop sputtering or cause that water level expands, thereby increase steam moisture.Installing arc buffering cover 3 just can be avoided the generation of the problems referred to above, and steam water interface runs into arc buffering cover 3 to be stopped, Speed Reduction, and water can freely fall, and vapour is entered in the baffle plate element by notch.Suitable good of the effect that arc buffering cover 3 separates can band water rate reduce by 30%～40% in steam water interface.Baffle plate 4 is arranged at arc buffering cover 3 tops, baffle plate 4 is blind shaped, and baffle plate 4 is mutually vertical with the gap of arc buffering cover 3, there are the angle of 30-60 degree in the blade of baffle plate 4 and the steam direction that blows out from arc buffering cover 3, baffle plate 4 is divided into two parts with the space in drum (drum) simultaneously, a part is water, and another part is steam water interface.Be still steam with hygroscopic water owing to entering vapour baffle plate 4 from arc buffering cover 3, proceed to separate in the baffle plates 4 of many foldings.
Secondary separation device comprises waveform impact-absorbing shell 7 and waveform separator 6, wherein waveform separator 6 herringbones are arranged on the both sides at steam fairlead 5 mouth of pipe places, the bottom intersection of the waveform separator 6 of both sides draws and collector pipe, make on the water surface of the isolated moisture of waveform separator 6 in collector pipe inflow drum, avoid the situation that it is carried by steam again or water droplet flashes to occur.Waveform separator 6 exists spacing and parallel waveform sheet metal to form by polylith, adjacent waveform sheet metal spacing is 10mm, corrugated sheet adopts the steel plate of 1mm to be pressed into, frame is made of the steel plate of adopting 6mm, after steam water interface entered drum process first separation device separates, larger water droplet was separated, but tiny water droplet is light because of its quality, be difficult to utilize the methods such as centrifugal force, gravity that it is separated from steam, and it is better to utilize adhesive force (adhesion) effect to carry out separating effect.Corrugated sheet separator 6 utilizes this principle to carry out work.Vapor stream is when corrugated sheet separator 6, be divided into many strands of steam flows, due to the adhesive force effect, water droplet in steam is sticked to form moisture film on corrugated sheet, and moisture film can cling the fine liquid particles in steam, the water of separating flows downward along the wooden partition of corrugated sheet and falls into the drum water capacity, and carbonated drink is further separated.waveform impact-absorbing shell 7 is arranged at steam fairlead 5 mouth of pipe places, it is arranged between steam fairlead 5 and waveform separator 6 in particular, it structurally has different from arc buffering cover 3 in first separation, role is also different, also have many notches on this arc buffering cover 7, but more intensive than the notch in the arc buffering cover 3 in first separation, each slot opening 4mm, the steam of notch spacing 10mm. by corrugated sheet separator 6 is only with seldom moisture, this arc buffering cover 7 can be blocked in tiny water droplet the outside, it can not be passed through, separate for the last time.The water droplet that is blocked in the outside drops in collector pipe by free gravity, then overflows to flow in the hydrospace from collector pipe.
