The invention relates to a tamping coke oven charging coke dedusting system, which is particularly suitable for tamping coke oven dust removal in the iron and steel industry. The system includes furnace top dust removal and coke side dust removal. A machine side dust removal system is added to the machine side of the tamping coke oven, and a coal charging dust removal system is formed by connecting the machine side dust removal pipeline with the furnace top dust removal pipeline; Coal dust removal and coke push dust removal share a set of coal push coke dust removal ground station. The invention overcomes the problems of heavy smoke from the side of the tamping coke oven and pollutes the environment during the coal charging process, and effectively solves the problems of large air volume for dust removal on the top of the furnace, lowering the furnace temperature, and affecting the service life of the coke oven.
Description
Technical field
The present invention relates to a kind of tamping coke oven coal-charging pushing dust removing system, be specially adapted to the steel industry tamping coke oven dust.
Background technology
Steel plant's tamping coke furnace produces a large amount of flue dust in the coal-charging pushing process, purified serious environment pollution as not capturing, and especially the pusher side problem of smoldering is quite serious.Because tamping coke furnace pusher side flue gas can not well capture, can only increase furnace roof flap valve dust pelletizing system ability, the cold air that causes like this entering carbonization chamber from pusher side increases, reduce the carbonization chamber temperature, influence the coke oven life-span, simultaneously a large amount of cold airs quickens and the briquette reflection, will produce more flue gas, thereby the formation vicious circle is unfavorable for coke oven production, increases investment and operating cost simultaneously.Therefore the tamping coke oven dust effect is very undesirable at present, influences the development of tamping coke furnace.
Summary of the invention
The tamping coke oven dust effect is undesirable in order to overcome, contaminated environment, big, the furnace roof flap valve dedusting air quantity of cold air amount that enters carbonization chamber increase problems such as investment height, operating cost height.The invention provides a kind of tamping coke oven coal-charging pushing dust removing system.
For realizing that the technical scheme that purpose of the present invention adopts relates to a kind of tamping coke oven coal-charging pushing dust removing system, comprise coke side dust pelletizing system and furnace roof dust pelletizing system, it is characterized in that: increase the pusher side dust removing system at the tamping coke furnace pusher side, form coal loading dedust system by pusher side dust removing pipeline and furnace roof dedusting pipeline connection; Adopt pneumatic transfer valve, the coke pushing dedusting earth station of coalingging is overlapped in realization dust collection for charging and coke pushing dedusting shared.
Adopt pusher side ventilation slot and pusher side dust removing pipeline, the manual blast balance apparatus of pusher side to form pusher side dust removing, realize capturing the volume of smoke that pusher side is emerged in the process of coalingging.
The invention has the beneficial effects as follows: adopt steel plant's tamping coke oven coal-charging pushing dust removing system, solved difficult problems such as serious, the contaminated environment of smoldering in the tamping coke oven coal-charging pushing process, reduce investment outlay, save operating cost.
Description of drawings:
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is a systematic schematic diagram of the present invention;
Fig. 2 is a plane of the present invention;
Among the figure: 1, pusher side ventilation slot, 2, the manual blast balance apparatus of pusher side, 3, the pusher side dust removing pipeline, 4, furnace roof flap valve, 5, the manual blast balance apparatus of furnace roof, 6, the furnace roof explosion-proof valve, 7, furnace roof dedusting pipeline, 8, the pneumatic transfer valve of pusher side, 9, coke side ventilation slot, 10, coke side dedusting pipeline, 11, the pneumatic transfer valve of coke side, 12, dedusting house steward, 13, coal-charging pushing dedusting earth station
The specific embodiment
Before selecting steel plant's tamping coke oven coal-charging pushing dust collecting process technology for use, at first determine the tamping coke furnace pusher side by calculating, furnace roof, the exhaust gas volumn that coke side produces, according to the tamping coke oven coal-charging pushing working system, the cycle of operation determines whether dust collection for charging and coke pushing dedusting switchover operation satisfy the dedusting requirement, determine locomotive flue gas trapping mode, calculate and determine furnace roof CO concentration, reasonable distribution pusher side and furnace roof dedusting air quantity etc., select suitable deduster, dedusting fan, the pusher side ventilation slot, the furnace roof flap valve, device parameters such as coke side ventilation slot, the capacity of equipment between each equipment are wanted and can be mated mutually.
Pusher side ventilation slot 1 is formed the tamping coke furnace pusher side dust removing with the manual blast balance apparatus 2 of pusher side, pusher side dust removing pipeline 3 among the figure; Furnace roof flap valve 4 is formed the furnace roof dedusting with the manual blast balance apparatus 5 of furnace roof, furnace roof explosion-proof valve 6, furnace roof dedusting pipeline 7; The tamping coke oven coal-charging dust pelletizing system is formed in pusher side dust removing and furnace roof dedusting, gathers the pneumatic transfer valve 8 of Guan Shangshe pusher side; Coke side ventilation slot 9 is formed the tamping coke furnace pushing dust removing system with coke side dedusting pipeline 10, the pneumatic transfer valve 11 of coke side; Realize the function of tamping coke oven coal-charging dust pelletizing system and the shared coal-charging pushing dedusting of pushing dust removing system earth station 13 by pneumatic transfer valve 8 of pusher side and the pneumatic transfer valve 11 of coke side.When dust collection for charging and coke pushing dedusting air quantity are inconsistent or tamping coke furnace repair between the campaign, can adopt fluid coupling that blower fan is carried out speed governing, energy savings; Adopt pneumatic transfer valve, shorten and to coaling and coke side dedusting switching time, both saved occupation of land, reduce operating cost again, make coaling and the two-in-one system applies scope of coke pushing dedusting more general; Under the downright bad situation of the terminal valve of systematic air flow deficiency, coke side or pusher side dust removing, adopt the method that balanced valve is set on dust removing tube, the protection dust removal installation.
Above Facilities Construction is finished, monomer test run and nothing meet test run no problem after, can move debugging, roughly process is: at first move the coke side dust pelletizing system, after treating that filter bag of dust collector hangs up coke powder uniformly, drop into dust collection for charging, at this moment the air quantity of regulating pusher side dust removing and furnace roof dedusting by manual blast balance apparatus 2 of pusher side and the manual blast balance apparatus 5 of furnace roof distributes, and makes both the flue gas trapping rate all reach designing requirement.
