By using above-mentioned technical proposal, dusty gas enters lower chambers from air inlet, obtains after filter bay assembly filters Purification gas flows into upper chamber, and takes upper chamber out of by active blower, and dust, which is trapped, to be saved bit by bit in lower chambers bottom surface.To cavity of resorption Before the dust of body bottom surface is removed, air inlet is closed, starts heating component, heating tube heats lower chambers bottom surface dust, starts simultaneously Active blower forms subnormal ambient in box house, and the steam in dust is rapidly evaporated and cabinet is discharged by active blower Outside, so that dust drying in lower chambers bottom surface is loose, cleaning is convenient.

Preferably, the lower chambers bottom surface has the dust heating tank equal and parallel with heating tube, described to add Heat pipe is parallel with dust heating tank and one-to-one correspondence is accommodated in dust heating tank, the notch side of the two adjacent dust heating tanks Edge is affixed.

By using by adopting the above technical scheme, the dust of lower chambers bottom surface is respectively positioned in dust heating tank, dust filling Thus heating tube heating effect and heating efficiency are improved in dust heating tank and the outside for being affixed on heating tube, reduce energy consumption.

Preferably, the dust heating tank bottom belt has the supporting element for being used to support heating tube, the dust heating The section semicircular in shape of its vertical length direction of slot, the axle center of the heating tube in the dust heating tank and the dust heating tank hang down The center of circle in the section of its straight length direction is overlapped.

By using above-mentioned technical proposal, self-heating conduction orientation, heating tube to the heating of the powder in dust heating tank more Add uniformly, avoids the slot bottom of dust heating tank from having powder heating in part insufficient, from the angle of heat radiation, the slot of dust heating tank Bottom is heated towards foveal reflex heat radiation, is improved energy utilization, is which thereby enhanced heating tube heating effect.

Preferably, the lower chambers side has the shoot door of salable closure, and the bottom surface of the lower chambers is being leaned on Nearly shoot door side has a dust collection slot of vertical dust heating tank length direction, and the dust heating tank is towards dust collection slot Side is arranged diagonally downward and is connected with dust collection slot.

By using above-mentioned technical proposal, dry loose dust can be because of it certainly after being heated in dust heating tank by heating tube Body gravity slides into dust collection slot, the dust in dust heating tank is removed, thus in pulsed bag filter filtration Under state, heating component can be started periodically to prevent dust agglomerations in dust heating tank.

Preferably, the supporting element include the connection strap being connect with the slot bottom of dust heating tank and with heating tube on the outside of The support portion being affixed, the connection strap are parallel with dust heating tank length direction.

By using above-mentioned technical proposal, supporting element is reduced to dust in dust heating tank along dust heating tank length direction The dynamic resistance of sliding, avoids dust from saving bit by bit in the slot bottom junction of connection strap and dust heating tank.

Preferably, the outside of the dust collection slot has the heating plate being affixed with its slot bottom.

By using above-mentioned technical proposal, heating plate can heat dust in dust collection slot, remove the steam in it, avoid Dust agglomerations bond in dust collection slot.

Preferably, the slot bottom of the dust collection slot is arc.

By using above-mentioned technical proposal, the slot bottom of dust collection slot is without dead angle, and cleaning is convenient, while heating plate is to dust Dust homogeneous heating in collecting tank.

Preferably, the bottom chamber includes lower end insertion bottom chamber with component, the cleaning component is cleaned Trachea, the drop-leg and several spray pipes being connected on drop-leg that are connected to trachea lower end；It is described to connect The upper end of tracheae is connected with cylinder；The spray pipe that the spray pipe can be aligned with heating tube outside.

By using above-mentioned technical proposal, the sprayable compression gas-pressure of spray pipe carries out heating pipe surface and dust heating tank Cleaning.

Preferably, with several installation locating plates that can be offseted with heating tube outside, the heating in the spray pipe It manages in one end insertion spray pipe far from dust collection slot and its outside is abutted against with installation locating plate.

By using above-mentioned technical proposal, locating plate is installed and abuts the fixed one end of heating tube far from dust collection slot, Positioning action is played in the installation process of heating tube and the use process of pulsed bag filter, is easily installed and reduces heating Tube vibration and axial float.

In conclusion the utility model has the following beneficial effects:

1. dusty gas, after filter bay assembly filters, dust therein, which is trapped, to be saved bit by bit in lower chambers bottom surface, to cavity of resorption Before the dust of body bottom surface is removed, air inlet is closed, starts heating component, heating tube heats lower chambers bottom surface dust, starts simultaneously Active blower forms subnormal ambient in box house, and the steam in dust is rapidly evaporated and cabinet is discharged by active blower Outside, so that dust drying in lower chambers bottom surface is loose, cleaning is convenient；

2. dry loose dust can slide into dust collection because of its own gravity after being heated in dust heating tank by heating tube In slot, the dust in dust heating tank is removed, thus under pulsed bag filter filtration state, can periodically start and add Hot component is to prevent dust agglomerations in dust heating tank.
