Detailed description of the invention
If Fig. 1 is to shown in 5: a kind of paraformaldehyde dust and emission-control equipment, remove including horizontal steam boiler 5 and cloth bag
Dirt device 1, described horizontal steam boiler 5 has burner hearth 51 and burner 4, and the fire-outtaking tube 41 of burner 4 is inserted in burner hearth 51, institute
State sack cleaner 1 and there is an air inlet and a gas outlet, also include water washing tank 2, air intake pump 3 and cloth compression ring 9, cloth compression ring
9 are positioned at boiler 5 burner hearth 51, and the gas outlet of sack cleaner 1 connects at water washing tank 2 tank bottoms, at water by downtake pipe 11
Cleaning of evaporator 2 tank deck is communicated with second exhaust pipe 12, and second exhaust pipe 12 one end connects through boiler 5 outer wall with cloth compression ring 9, air intake pump
3 are arranged on second exhaust pipe 12；
Described water washing tank 2 includes tank body 21, is communicated with water inlet pipe 22 and drain pipe 23 on tank body 21, in tank body 21 by
It is interval with multi-disc filter screen 24 the most successively, during use, needs to pour in tank body 21 clear water, the powder that sack cleaner 1 is discharged
End and waste gas can be washed by clear water in tank body 21, and the clear water after being washed is the formalin of low solubility, when washing, and washing
Tank 2 can filter out paraformaldehyde powder, and the paraformaldehyde waste gas after washing then can enter into burner hearth from second exhaust pipe 12
Burn in 51.
Described cloth compression ring 9 includes annulus 91, is provided with a toroidal cavity 94 in annulus 91, installs on annulus 91 internal face
