[0021] When a zero-air-consumption blast-heated regenerative desiccant dryer in this solution is working, the side-flow blower 15 is started by the electrical control box 10. The side-flow blower 15 starts to draw air. The air enters the interior of the heat exchanger 8 from the air inlet opened on the heat exchanger 8. Through the provided T-shaped tee 507, the air is drawn into the side-flow blower 15, and is discharged through the provided seventh connecting pipe 506.

Since a key block is fixedly provided on the surface of the limiting slide plate 708, and a key groove is formed in the inner wall of the connecting barrel 701, and the key block is slidably connected to the groove wall of the key groove, the limiting slide plate 708 can only slide horizontally back and forth.

The slide rod 710 drives the filter rod 707 to move backward, and the spring 709 is compressed. When the ventilation performance of the filter rod 707 is poor, the wind wheel 706 will gradually stop rotating, and finally the spring 709 will reset, causing the filter rod 707 to impact on the baffle 508, shaking off the particulate matter adhered to the surfaces of the baffle 508 and the filter rod 707. When filtering the gas, the wet particulate matter is difficult to adhere to the surface of the filter plate, extending the service life of the filter plate and facilitating the use of the device.
