Among the figure: the pre-spray equipment 10-of 1-mobile set dust hood 2-conducting valve 3-conduction pipe 4-furnace roof control of dust main 5-stove group switching valve 6-connecting tube 7-sack cleaner 8-speed governing type dedusting fan 9-chimney
Embodiment
Be described in detail particular content of the present utility model below in conjunction with accompanying drawing:
See Fig. 1, heat recovery coke oven mobile bell-type pusher side dust removing device comprises portable dust gathering arrester 1, normally closed type conducting valve 2, conduction pipe 3, furnace roof control of dust main 4, normally closed type stove group switching valve 5, connecting tube 6, sack cleaner 7, speed governing type dedusting fan 8, pre-spray equipment 9, chimney 10.Conduction pipe 3 is located at coke oven door top, every hole, normally closed type conducting valve 2 is located on the conduction pipe 3, one end of conduction pipe 3 and 4 connections mutually of furnace roof control of dust main, the other end is positioned at the coke oven door top, be used for and 1 butt joint of portable dust gathering arrester, also be provided with normally closed type stove group switching valve 5 at furnace roof control of dust main 4 one ends of every group of stove group, furnace roof control of dust main 4 connects sack cleaners 7 by connecting tube 6, sack cleaner 7 connects speed governing type dedusting fan 8, and speed governing type dedusting fan 8 connects chimney 10; Every cover vehicle of coke oven only need be joined a portable dust gathering arrester 1, (also can be equipped with a plurality of as required), the both sides of portable dust gathering arrester 1 are provided with smoke stop plate, coke oven do not carry out coke pushing, when coalingging operation, portable dust gathering arrester 1 is placed on the coke oven machine side vehicle or is placed on coke oven machine side does not influence coking technique near coke oven optional position; When a certain hole coke oven carry out coke pushing, when coalingging operation, by coke oven machine side vehicle or pusher side isolated plant portable dust gathering arrester 1 is moved to the top and conduction pipe 3 tight butts of this hole coke oven door, make portable dust gathering arrester 1 cover the top before this hole coke oven door.Pre-spray equipment 9 and sack cleaner 7 preceding connecting tubes 6 are connected, in sack cleaner 7 forward connection pipelines 6, spray into sorbent material, can absorb nuisance in the flue dust, can prevent the filter bag in the viscous substance bonding sack cleaner 7 in the flue dust simultaneously, prolong the work-ing life of filter bag.
The working process of the utility model heat recovery coke oven mobile bell-type pusher side dust removing device is described below:
When a certain hole coke oven carry out coke pushing, when coalingging operation, by coke oven machine side vehicle or pusher side isolated plant portable dust gathering arrester 1 is moved to the top and conduction pipe 3 tight butts of this hole coke oven door, make portable dust gathering arrester 1 cover the top before this hole coke oven door.Under the effect of speed governing type dedusting fan 8, the flue dust that portable dust gathering arrester 1 is trapped, entering sack cleaner 7 by normally closed type conducting valve 2, conduction pipe 3, furnace roof control of dust main 4, normally closed type stove group switching valve 5, connecting tube 6 successively purifies, the nuisance that dust with the dust is carrier captures, and the gas after being cleaned is drained into atmosphere through chimney 10.In the dust removal process, pre-spray equipment 9 can absorb the NO that contains in the flue dust by spray into sorbent material in connecting tube 6 before sack cleaner 7
