Abstract
The invention relates to the technical field of coke oven dedusting system, and especially relates to a dedusting technology of a coke oven dedusting system. The coke oven dedusting system comprises a main dedusting pipeline, a dedusting pipeline, a pulse bag type collector, an ash bin, a dedusting blower fan, a flue dust pipeline and a dedusting chimney. During operation in winter, flue dust enters into the newly added dedusting pipeline through the main dedusting pipeline; The newly added dedusting pipeline is provided with a dedusting pipeline valve, which is closed; a flame arrester is omitted; a dedusting branch pipeline is equipped with a draining water seal and added with a condensate water seal to discharge condensate water in the branch pipeline; the dedusting pipeline is newly added with an emergency valve; an emergency valve moving backwards technology is employed to satisfy blower fan need during low speed running and thoroughly solve a problem of condensation caused by excessive low temperature of the deduster in winter.
Description
Technical field
The present invention relates to the coke oven dust system process, belong to coke oven dust systems technology field, refer to a kind of coke oven dust system dust removing technology especially.
Technical background
In northern coke-oven plant coke oven ground dedusting system winter operation process, flue gas especially reduces obviously through temperature behind the spark arrester through long cleaning shaft, and arm has the water-setting junction phenomena before the fly-ash separator, and can not in time discharge, and finally gets in the fly-ash separator.Simultaneously; When the blower fan low-speed running; Get into fly-ash separator from a large amount of freezing airs of very valve suction through cleaning shaft, reduced the temperature in the fly-ash separator, and water vapor further condensation is got off; Drip to very valve and icing rapidly, the water of condensation that gets in the fly-ash separator becomes the mud shape to be bonded at fly-ash separator cloth bag surface together with dust in flue gas.The inventor is through research of technique, according to coke oven ground dedusting system winter operation existing problems, original technology carried out technological improvement, and dust removing effects is good, make the dust-removal system in the winter time can steady running, played the effect of consumption reduction, energy-saving and emission-reduction.
Summary of the invention
The invention provides a kind of coke oven dust system dust removing technology, the preceding flue-gas temperature of fly-ash separator was low excessively when purpose was effectively to solve winter operation, had taked to get rid of spark arrester, let flue gas directly get into fly-ash separator through arm; On the dedusting small transfer line, add the water of condensation water seal, the water of condensation in the arm is discharged; Taked during winter operation very to move technology behind the valve, the needs when promptly having satisfied the blower fan low-speed running, the fly-ash separator temperature is crossed low and condensation trouble when also thoroughly having solved the fly-ash separator winter operation.
The present invention is a kind of coke oven dust system dust removing technology, comprises dedusting main pipe line, cleaning shaft, pulse bag type dust collector, Hui Cang, dedusting fan, fume ducts, Dust removal chimney composition, it is characterized in that: during winter operation; Flue dust gets into newly-increased cleaning shaft 13 through dedusting main pipe line 1, and newly-increased cleaning shaft 13 is provided with cleaning shaft valve 19, closes cleaning shaft valve 14; Get rid of spark arrester 2; Dedusting small transfer line 6 is provided with drain water seal 7, on the dedusting small transfer line, adds the water of condensation water seal, and the water of condensation in the arm is discharged; Cleaning shaft 17 is provided with newly-increased very valve 10, has taked very to move technology behind the valve.
The flue dust that coking coke pushing coal process produces gets into dedusting main pipe line 1 through coke guide or smoke guiding bogie through cleaning shaft 12; Get into newly-increased cleaning shaft 13 by dedusting main pipe line 1, newly-increased cleaning shaft 13 is provided with cleaning shaft valve 19, during winter operation; Open cleaning shaft valve 19 on the newly-increased cleaning shaft 13; Close cleaning shaft valve 14, taked to get rid of spark arrester 2, let flue gas directly get into fly-ash separator through arm; Get into dedusting small transfer line 6 by newly-increased cleaning shaft 13 again, dedusting small transfer line 6 is provided with drain water seal 7, on the dedusting small transfer line, adds the water of condensation water seal, and the water of condensation in the arm is discharged; Dedusting small transfer line 6 gets into cleaning shaft 16, and cleaning shaft 16 directly gets into pulse bag type dust collector 3, and pulse bag type dust collector 3 is provided with grey storehouse 11; Directly get into dedusting fan 4 through cleaning shaft 17; Cleaning shaft 17 is provided with newly-increased very valve 10, has taked during winter operation very to move technology behind the valve, and cleaning shaft 18 directly gets into Dust removal chimney 5; Needs when promptly having satisfied the blower fan low-speed running, the fly-ash separator temperature is crossed low and condensation trouble when also thoroughly having solved the fly-ash separator winter operation.
Get into dedusting small transfer line 6 through newly-increased cleaning shaft 13 and get into pulse bag type dust collector 3; Through the flue dust process dedusting fan 4 after pulse bag type dust collector 3 filtrations; Finally enter atmosphere by Dust removal chimney 5; When the blower fan low-speed running, suck air from newly-increased very valve 10, guarantee that blower fan normally moves.
Beneficial effect
Before this project reconstruction, because plant area is located in northeast, winter minimum temperature reaches below-30 ℃; Flue gas especially reduces obviously through temperature behind the spark arrester through the long pipeline that surpasses 100 Miho Dockyard N1600mm, and the flue gas top temperature is no more than 20 ℃ before the fly-ash separator, sometimes even lower; Arm has the water-setting junction phenomena before the fly-ash separator; And can not in time discharge, finally get in the fly-ash separator, worsen the cloth bag environment.And when the blower fan low-speed running (discharge of the coke, the coal gap, this moment, rotation speed of fan was 180r/min), get into fly-ash separator from a large amount of freezing airs that are located at the very valve suction before the fly-ash separator through cleaning shaft, further reduce the temperature in the fly-ash separator.
After this project reconstruction, this dust-removal system safe and stable operation surpasses 2 years at present, and dust removing effects is good.This project has been revised the technology operating scheme of original design institute, makes the dust-removal system in the winter time can steady running, and this scheme can be promoted by similar coal chemical enterprise in the north, is with a wide range of applications social benefit and good in economic efficiency.
