[0033] The working principle of this utility model is as follows: Figure 1-4 shown.

[0034] The first-stage decompression recovery tank module 1 is used to reduce the pressure of the airflow blown by the dust suction centrifuge or the pressure of the airflow blown by the pipeline to empty the ash. The airflow and dust with pressure enter the tank body of the first-stage decompression recovery tank module 1. The pressure of the airflow becomes weaker in the large space, and the dust sinks with its essential weight. The high-pressure airflow is decompressed by the first-stage decompression recovery tank module 1, and then decompressed and recovered by the second-stage decompression recovery tank module 2. The dust and powder are then recovered and then enter the polyester bag dust collector module 3 for fine dust removal, filtering the dust and airflow. The first-stage decompression recovery tank module 1, the second-stage decompression recovery tank module 2 and the polyester bag dust collector module 3 realize the movable function through the movable base. The movable base is not shown in the figure. It is usually used by setting movable wheels on the base.

[0035] The first-stage decompression recovery tank module 1 is air-intaken through the first air inlet 101, so that the airflow and dust enter the first-stage decompression recovery tank module 1 for decompression. The airflow after decompression carries part of the dust through the first air outlet 102 and enters the second-stage decompression recovery tank module 2 for further decompression. At the same time, part of the dust is also deposited in the first-stage decompression recovery tank module 1, and this part of the dust is recovered through the first recovery port. The second-stage decompression recovery tank module 2 is connected to the first air outlet 102 through the second air inlet 201, so that the airflow and dust can enter the second-stage decompression recovery tank module 2 for further decompression and precipitation. The airflow after decompression enters the polyester bag dust collector module 3 through the second air outlet 202 for the final dust removal stage. The dust deposited in the second-stage decompression recovery tank module 2 and the dust falling from the ash outlet 203 are recovered through the second recovery port 204. The polyester bag dust collector module 3 introduces airflow and dust through the dust removal air inlet 308, and filters and removes dust through the polyester bag 306. The polyester bag dust collector module 3 adopts the structure of an upper blind plate 304 and a lower blind plate 305 to realize the function of removable and replaceable filter element. The upper blind plate 304 is provided with a vibration hammer 307 to shake off the dust attached to the polyester bag and drop it into the lower shell 303, and finally fall into the secondary pressure reduction recovery tank module 2 through the lower ash port 203 for recovery.

[0036] Preferably, the first-stage decompression recovery tank module 1 can safely withstand a pressure of 1 MPa or more. The second-stage decompression recovery tank module 2 can safely withstand a pressure of 1 MPa or more. The polyester bag dust collector module 3 can safely withstand a pressure of 0.8 MPa or more.

[0037] In this embodiment, the first and second air bag assemblies 4 and 5 have identical structures, using an air cylinder connected to an external air source. The air nozzle and nozzle extension tube provide a distribution of blowing ports around the ash tank outlet, assisting in the relaxation of the ash material within the tank and increasing pressure within the tank. Preferably, the number of air holes is 8 to 12. Joints are welded to the air holes using steel internal tooth straight-through joints.

[0038] Furthermore, when the first-stage decompression recovery tank module 1 is operating to recover powder, pressurized gas is input through the first gas bag assembly 4 in the tank to realize the function of conveying the precipitated powder in the tank.

[0039] Before transporting the recovered powder, the valves of the first air inlet 101 and the second air inlet 201 of the first-stage decompression recovery tank module 1 must be closed to form independent spaces in the tank body of the first-stage decompression recovery tank module 1 before the dust recovery operation of the first-stage decompression recovery tank module 1 can be carried out.

[0040] When the first-level decompression recovery tank module 1 is operating to transport the powder in the tank, the external pressure gas source is turned on, and the pressure gas enters the tank through the gas bag in the tank into a main pipeline. When the pressure gas is added to a certain pressure in the tank, such as the air pressure of 0.38-0.7MPa, the recovery port 103 valve is opened, and the powder is transported to another storage tank through the pipeline for storage.

[0041] Before transporting recovered powder, the valves of the second air inlet 201 and second air outlet 202 of the secondary decompression recovery tank module 2 must be closed, creating an independent space within the secondary decompression recovery tank module 2. During operation, the external pressure gas source is opened, and the pressurized gas enters the tank through the pipeline of the second air bag assembly 5 inside the tank. When the pressurized gas reaches a certain pressure in the tank, such as 0.38-0.7MPa, the second recovery port 204 is opened, and the powder is transported through the pipeline to another storage tank for storage.

[0042] When the polyester bag dust collector module 3 is working, the lower ash port 203 needs to be closed to form a polyester bag dust removal space, so that the pressurized airflow and the remaining dust can be better filtered in the polyester bag 306, and the filtered dust is stored in the conical flow hopper under the bag, and the pressurized air dust is discharged through the air outlet 309.

[0043] The above embodiments of the present invention are described in detail. However, the above contents are only preferred embodiments of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
