Abstract
The invention discloses a heating device for a cooking boiler. The device belongs to a heating jacket part of an experimental cooking boiler body, and is applied to heating the cooking boiler. A traditional heating manner for the cooking boiler comprises resistance trace heating and steam heating, and the temperature precision in the heating process is difficult to control. Electric heating is slow, thus a short circuit is easily caused; due to the high pressure, the steam heating process has hidden troubles and complex facilities are provided. The heating device heats up heat conduction liquid in a cavity which is formed between the heating device and the cooking boiler body, so that the cooking boiler body is heated up in an intermittent manner; the heat conduction liquid is integrally coated on the cooking boiler body, so that the cooking boiler is quickly, uniformly and stably heated up; the heating device is kept in the normal pressure the same as the atmosphere in the heating process, additional pressure is not applied, and external vapour is not accessed, thus the facilities are simple and the operation is safe; a rotary part is added to achieve the synchronous rotation of the cooking boiler and the heating device.
Description
Technical field
The present invention relates to a kind of heater of the experiment type digester like pulp cooking experiment usefulness, this device can apply to paper industry, and the pot body of the digester of chemical fibre industry and textile industry and chemical industry heats.
Background technology
The mode of heating of current experiments type digester can be divided into the direct heating of resistance wire basically and water vapour intermittently heats two kinds of forms.
The direct-fired digester of resistance wire, its firing rate is fast, because the thermal storage performance of resistance wire, after digester reached the boiling temperature requirement, even cut off the electricity supply, resistance wire also can continue heat release, caused the accurate control difficulty of temperature; And often predefined boiling temperature all can be broken through the several years, and What is more will break through nearly ten degree of design temperature, thereby causes the boiling raw material to receive temperature fluctuation and produce and over-cook or situation that half steaming is even.In addition, the direct-fired digester of resistance wire is owing to can not accomplish the positive confinement of the collet seam of heater; And be unfavorable for after the positive confinement safeguarding and overhauling, therefore, cooking liquor appears or other liquid infiltrate through collet and get into heater through regular meeting; Especially be penetrated into the resistance wire surface; Cause burning or the generation of nocuity accident such as digester heating system short circuit of resistance wire, not only influence pilot production, more have bigger potential safety hazard.
The digester that steam intermittently heats, because the thermal conductive resin of metal, heating steam is meeting condensation gradually in to the process of digester heating; In heating jacket, form a large amount of condensed waters, the untimely discharge of condensed water can not charge into enough steam digester will be heated; Therefore steam-heated efficient and flexibility receive serious restriction, and very easily cause the half-cooked or even phenomenon of half steaming of boiling raw material, adopt the Steam Heating digester certainly will need supporting steam transmission system in addition; Make experiment type digester structure complicated; Be unfavorable for experimental implementation, and Steam Heating needs operation with high pressure, have serious potential safety hazard.Just because of above-mentioned many factors, adopt the few of steam-heated experiment type digester practice instantly.
Therefore, adopt existing mode of heating that the boiling raw material is stablized, efficiently evenly boiling; And there are defectives such as operational hazards or heater be loaded down with trivial details.Develop a kind of temperature control that can realize stablizing so, guarantee that the boiling raw material is heated evenly, easy to operate, system's digester heater flexibly saves resource for improving conventional efficient, and the repeatability that ensures experiment is with extremely important.
Summary of the invention
The purpose of this invention is to provide a kind of equilibrium temperature control that can realize digester, can be so that the boiling raw material be evenly heated, easy and simple to handle, the normal pressure heater of experiment safety.
For reaching above purpose, the present invention intends and adopts following technical scheme to carry out:
1. above-mentioned purpose realizes that by such digester heater promptly this device is for having: heating jacket housing (1), stay pipe (2), heating rod (3); Heating rod hole (4), discharge orifice (5), thermometer hole (6), overfall (7); High temperature swivel joint (8), expansion tube (9), steam vent (10); Plug (11), thermocouple (12), the digester heater of intelligent temperature controller (13) assembly.
2. the heating jacket housing (1) that can tightly be configured on the digester pot body can be realized seamless the cooperation with the external wall of digester; Forming a cavity between heating jacket housing and the external wall of pot is cavity; Inside cavity is added heat-conducting liquid; Like conduction oil, the heating-up temperature of liquid is controlled more easily, it is more even through liquid the pot body to be heated its heating process.
3. the pottery insulation supporting tube (2) that is fixed on the heating jacket enclosure interior is a hollow out type hollow ceramic insulation tube, and stay pipe (2) is fixed in above the heating rod hole (4), is used to place heating rod in the pipe, avoids heating rod directly to contact with the heating jacket housing.
4. be fixed on the heating rod (3) on the heating jacket housing, utilize heating rod that the heat-conducting liquid of heating jacket enclosure interior is heated, the fire end of heating rod is positioned in the stay pipe (2).
5. the heating rod hole (4) on the heating jacket housing; For being positioned at the metal tube that two ends on the heating jacket housing all have inside and outside two screw threads, or metal aperture, inboardly closely be connected with stay pipe; Form passage and be convenient to the insertion of heating rod heating part, the outside is used for fixing heating rod.
6. be positioned at the discharge orifice (5) above the heating jacket housing, be used for fixing plug (11), in order to the heat-conducting liquid or the air of discharging heating jacket enclosure interior.
7. thermometer hole (6) is positioned on the heating jacket housing, is used to lay and stationary heat galvanic couple (12), and thermocouple (12) carries out temperature detection to the heat-conducting liquid in the heating jacket housing.
8. heating rod (3) is connected in intelligent temperature controller (13) simultaneously with the interior thermocouple of thermometer hole (6), and heating process is measured and control in real time, prevents to continue to heat.
9. overfall (7) is positioned on the heating jacket housing, is used for overflow and goes out volumetric expansion after heating and unnecessary heat-conducting liquid.
10. expansion tube (9) is realized being tightly connected through high temperature swivel joint (8) and overfall (7); Have steam vent (10) above the expansion tube (9); High temperature swivel joint (8) guarantees that heating device shell (1) can rotate with respect to expansion tube (9); And expansion tube (9) is used for receiving the high temperature heat-conducting liquid that is heated and overflows from overfall (7), and steam vent (10) then ensures the timely discharging of gas in the expansion tube.
