Specific embodiment
The utility model is described in detail below in conjunction with attached drawing and specific embodiment, in the signal of this utility model
Property embodiment and explanation be used to explain the utility model, but be not intended to limit the scope of the present invention.
As shown in Figure 1 and Figure 2, the hot precipitator of the invention using flowable particle filter layer dedusting, including by shell
The body of deduster that body 1 and inner housing 2 form, inner and outer shell centre form heat tracing collet, are used to through heat-carrying gas to dedusting
Device ontology carries out heat tracing, prevents in low temperature the condensable dusty gas for liquid in dust removal process because of temperature reduction, make to
The cooling condensation of purification gas.Two pieces of sieve plates 6 are internally provided in deduster inner housing 2, by body of deduster internal insulation at not
Same workspace, i.e. inlet chamber 7, filter chamber 4 and outlet chamber 15.3 filter medium of filter medium import is equipped in filter chamber 4 to go out
Mouth 11；Filter medium continuously enters body of deduster from filter medium import 3, then by the continuously discharge of filter medium outlet 11, mistake
Filter medium is that absorption property is stronger blocky or granular adsorption medium, the filter layer that filter medium is formed to dusty gas into
Row filtering.It is equipped with dusty gas import 17 and cinder-discharging port 10 in inlet chamber 7, opens up pyrolysis gas secondary inlet at the top of inlet chamber 7
5；The condensable gas for liquid when needing in dedusting gas containing low temperature, dusty gas enter inlet chamber by dusty gas import 17
7, a small amount of dirt is settled in inlet chamber 7, remaining dusty gas enters outlet chamber 15 by the filter layer in filter chamber 4 after filtering,
Gas after final purification is discharged by purified gas outlet 16.Filter layer is continuous moving.
Heat-carrying gas is equipped on the heat tracing collet formed among inner and outer shell to import and export；Body of deduster bottom is provided with
Hold-down support 8 and sliding support 12.
Heat-carrying gas of the temperature above cinder-discharging port 10 of 300~600 DEG C of heat-carrying gas a part by body of deduster bottom
Body import I 9 enters the heat tracing collet that outer housing 1 and inner housing 2 are formed, and carries out heat tracing to the ash bucket of inlet chamber 7；Another part by
The heat-carrying gas import II 13 of 15 outer wall lower part of outlet chamber enters the heat tracing collet that outer housing 1 and inner housing 2 are formed, after circulation by
14 discharge of heat-carrying gas outlet on 15 outer wall top of outlet chamber, carries out heat tracing to deduster, filter environment is kept to reach technique
It is required that temperature.
Pyrolysis gas secondary inlet 5 is opened up, at the top of inlet chamber 7 for entering the dusty gas that other parts generate.Into
Open up level-sensing device interface I 19 and level-sensing device interface II 20 on the ash bucket of air cavity 7, connection level-sensing device detects dust accumulation height, periodically into
Row unloads grey cleaning, prevents dirt in 7 building up inside of inlet chamber, influences dusty gas purification.Cinder-discharging port in body of deduster bottom
Rapping apparatus 18 is set at 10, is blocked after preventing buildup, grey cleaning is unloaded in influence.Inspection is opened up respectively on inlet chamber 7, outlet chamber 15
