The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done to describe in detail further.
As shown in Figure 1; A kind of development machine is with pipe curtain-wet type density gradual change fiber grid compound type dust remover; Comprise casing 4; In casing 4, be provided with pipe curtain 1, density gradual change fiber grid 5 and labyrinth 6; Between said pipe curtain 1 and density gradual change fiber grid 5, be provided with sparge pipe 2 with waterfog head 3; The other end of said density gradual change fiber grid 5 is connected with an end in labyrinth 6, and the other end in labyrinth 6 is connected with blower fan 8 through reducing pipe 7; Be provided with the sludge bin 11 of dry ash storehouse 9, density gradual change fiber grid, the sludge bin 14 and the cyclic water tank 10 in labyrinth in the lower end of casing 4; Said dry ash storehouse 9 is connected with the bottom of pipe curtain 1; The sludge bin 11 of said density gradual change fiber grid is connected with the bottom of density gradual change fiber grid 5; The sludge bin 14 in said labyrinth is connected with the bottom in labyrinth 6; In said cyclic water tank 10, be provided with strainer, cyclic water tank 10 is connected with sparge pipe 2 through water pump; Water after strainer filters sprays from waterfog head 3 through water pump, sparge pipe 2 again; Said strainer is used for purifying and dedusting, and adopting purifies waste water can prevent that waterfog head 3 from stopping up.
