Through the design of the annular base 21 and the support sleeve 22, the hydrocyclone body 1 can be stably supported by the ground.

[0018] As one implementation method in this embodiment, such as Figure 2As shown, a support arm 23 is fixedly installed on the inner wall of the annular base 21. A smooth rod 25 is fixedly installed on the top of the support arm 23. A movable seat 26 is slidably connected to the outer wall of the smooth rod 25. An elastic element 24 is fixedly installed on the top of the support arm 23. The top of the elastic element 24 is fixedly connected to the bottom of the movable seat 26.

The movable seat 26 will slide vertically down on the outer wall of the smooth rod 25, while compressing the elastic element 24. Then pull out the collection cylinder 28 at the bottom outlet 13 and then release the movable seat 26. When installing the collection cylinder 28, first push the movable seat 26 downward, then insert the collection cylinder 28 into the bottom outlet 13 and then release the movable seat 26. Through the restoring force of the elastic element 24, the movable seat 26 can be moved upward to abut against the collection cylinder 28 from the bottom, thus realizing the installation function.

[0019] As one implementation method in this embodiment, such as Figure 2 As shown, a limiting protrusion 27 is fixedly installed on the top of the movable seat 26, and the collecting tube 28 is movably inserted into the inner cavity formed by the limiting protrusion 27.

The end of the first output pipe 32 is connected to the subsequent equipment for flue gas treatment. The electric cylinder 36 is controlled to extend and retract according to the flue gas condition, which drives the gate 35 to move left and right in the inner cavity of the guide box 31. When it is located at the leftmost position, the inner cavity of the first output pipe 32 is cut off, and the flue gas is transported to the other cyclone body 1. When the gate 35 is located at the rightmost position, the inner cavity of the second output pipe 33 is cut off, so that the flue gas enters the interior of the subsequent equipment.
