[0020] When the application is used, the flue gas flowing out of the drying cylinder carries the dry powder into the first vertical pipe 2 through the air inlet pipe 1. The valve 6 of the second vertical pipe 5 is closed, and the valve 6 of the first horizontal pipe 3 is opened. The flue gas enters the outer pipe 9 through the first horizontal pipe 3 and passes through the dust cloth bag 12. The dry powder remains in the dust cloth bag 12, and the flue gas enters the drying cylinder again after being heated by the heat exchanger 8. After the dust cloth bag 12 collects for a period of time, the originally opened valve 6 is closed, and the originally closed valve 6 is opened. The flue gas flows through the second horizontal pipe 4 and is collected by the corresponding dust cloth bag 12. Then the outer pipe 9 is disassembled, and the dry powder is poured out of the dust cloth bag 12 to realize the collection of the dry powder. When the flue gas is heated by the heat exchanger 8, it can quickly reach the required temperature due to its own temperature, thereby reducing the power consumption of the heat exchanger 8 to a certain extent.
[0021] The first horizontal pipe 3 and the second horizontal pipe 4 are fixedly sleeved with an annular pipe 11. The outer side of the annular pipe 11 is provided with external threads.
