Then, by the elastic force of the reset spring one 20 and the reset spring two 22, the collection box 12 can be refixed without external force. The quick disassembly function makes the replacement of the collection box 12 and the discharge pipe 13 easier. When these components are worn, corroded or need to be upgraded to a more efficient model, they can be replaced in time without causing great impact on the structure and operation of the entire desulfurization device.
