Description
Technical field
The utility model relates to high-temperature flue gas purification dust arrester, particularly a kind of gas-filtering device with heater.
Background technology
As shown in Figure 1, pneumatic filter comprises filter body, and filter body comprises filter cylinder 10 and filter core (not shown in figure 1).The filter core of filter element is rigidity filter core, rigidity filter core can be intermetallic compound, the porous tubing that such as intermetallic Fe-Al compound is prepared into, such rigidity filter core is suitable for the filtration of high temperature and high pressure gas, but, at present, in high-temperature flue gas purification processing procedure, condensation can be there is in the low boiling component entered in the high-temperature flue gas of filter along with the course of conveying temperature of flue gas reduces, at air inlet pipe inwall congregate, time, long meeting formed deposit in air inlet pipe, particularly the low boiling component of condensation in the filter will permanent blocking filter core duct, rigidity filter core cost also more general filter core is high, require higher to the maintenance of rigidity filter core also more general filter core, deposits even can damage filter plant, many troubles and loss can be brought to the owner.At present, for avoiding the generation of above-mentioned situation, the method usually taked adds insulation material 11 in air inlet pipe outside, prevents low boiling component Yin Wendu in the high-temperature flue gas of import department from reducing and producing phase transformation.
The air inlet pipe external insulation material of high-temperature gas filter is generally the heat-insulating material such as rock wool or alumina silicate fiber felt, but these two kinds of materials all exist the shortcoming that water imbibition is large, water proofing property is poor.Usual heat-insulation layer outside adopts galvanized iron sheet as protective layer, is fixed by rivet.Frequent meeting, because drenched with rain, causes insulation material to meet water and lost efficacy, lose heat insulation effect.In addition, the part that air inlet pipe stretches in filter does not have Insulation, easily causes temperature to reduce, and for the pneumatic filter using rigidity filter core, cannot meet it preferably and prevent the requirement that in gas, low boiling component is separated out.Therefore need badly and should make further improvement and bring new ideas to prior art and solve the problems referred to above.
Utility model content
Technical problem to be solved in the utility model is, for the defect that above-mentioned prior art exists, provides a kind of gas-filtering device with heater.
The technical solution adopted in the utility model is, a kind of gas-filtering device with heater, comprise filter body, air inlet pipe, described air inlet pipe stretches in filtration body, described filter body comprises filter cylinder and filter core, it is characterized in that: install electric heating assembly in air inlet tube wall periphery, electric heating assembly stretches in filter body.
Be further, described electric heating assembly comprises jacket pipe, electric heater unit, interstar connection room, control unit, jacket pipe is placed in outside air inlet pipe entrance and air inlet pipe cecum, in jacket pipe, electric heater unit is installed, interstar connection room is placed in outside air inlet pipe entry wall, is connected respectively with electric heater unit and control unit line.
Further, described jacket pipe inwall respectively arranges positioning guide rail up and down.
Respectively arrange positioning guide rail up and down at jacket pipe inwall, such structure is convenient to the installing/dismounting of heating tube, and prevents it from rotating around jacket pipe axis.
Further, described electric heating assembly comprises electric heating tube, heating element heater, grid spacer, tube sheet, and electric heating tube is evenly distributed on jacket pipe inside, and successively through tube sheet and grid spacer, heating element heater is placed in electric heating tube.
Electric heating tube is evenly distributed on jacket pipe inside, and the gas in air inlet pipe is heated evenly, and realizes fixing successively through grid spacer and tube sheet by electric heating tube in jacket pipe.
Particularly, described heating element heater is resistance wire.
Converting electric energy is energy in resistance by resistance wire, distribute heat thus.
Further, described electric heating tube is stainless steel tube.
Adopt stainless steel, prevent electric heating tube from meeting scale erosion, damage electric heating tube.
Further, mounting temperature sensor near electric heating tube.
Electric heater unit by being installed on the temperature sensor measurement temperature near electric heating tube, and feeding back to control unit and controls heating element heater.
Further, electric heater unit and jacket pipe adopt Flange joint, and are fastened by bolts.
Further, fill insulant material in described jacket pipe.
The beneficial effect that the utility model brings:
One, can ensure that air inlet pipe high-temperature flue-gas can not decline, effectively prevent low boiling component from separating out.
Two, heating-up temperature can regulate according to intake air temperature, controls safe and reliable.
Three, heating effect can not be reduced because of insulation failure outside pipeline.
Four, compact conformation, floor space is little.
