Abstract
The invention provides a pre-spraying system and a pre-spraying method of a coke oven ground dedusting station and relates to a pre-spraying system and a pre-spraying method of a coke oven dedusting station, solving the problem that the existing pre-spraying system is severely influenced by a temperature and a pre-spraying material so as to result in a poor pre-spraying effect. The pre-spraying system is characterized in that the side wall of a dust storing chamber of the system is provided with an air intake and a pre-spraying hole which are oppositely arranged; an air outlet of a compressed air pipeline is communicated with the air intake of the dust storing chamber; the air intake of the compressed air pipeline is a compressed air inlet; the pre-spraying material inlet of the pre-spraying pipeline is communicated with the pre-spraying port of the dust storing chamber; the pre-spraying material outlet of the pre-spraying pipeline is communicated with a pre-spraying material inlet of a coke oven; a butterfly gate is arranged between the dust storing chamber and a No.1 flexible connection pipe; and the pre-spraying material is coke powder. The pre-spraying method comprises the following steps: feeding the coke powder generated when the coke oven works into a dust putting cabin and feeding into the dust storing chamber; and blowing the coke powder entering into the dust storing chamber into a dust collecting pipeline through the pre-spraying pipeline by utilizing the compressed air, thereby achieving the pre-spraying of the coke oven ground dedusting station. The pre-spraying system and the pre-spraying method are suitable for the pre-spraying process of the coke oven ground dedusting station.
Description
Technical field
The present invention relates to coke oven dust station spray system in advance and preparatory spray method.
Background technology

Summary of the invention
The present invention is influenced seriously by temperature and spray material in advance in order to solve existing preparatory spray system, cause spraying in advance the problem of weak effect, thereby a kind of coke oven ground station for dust removal spray system in advance and preparatory spray method are provided.
A kind of coke oven ground station for dust removal sprays system in advance; It comprises and connects grey tank car; It comprises puts grey storehouse, form valve, compress wind pipeline, butterfly valve, hose connector, spiral dust unloadnig apparatus, No. two hose connectors, ash storage room and jet pipe roads in advance; The preparatory spray material outlet of putting grey storehouse is communicated with the preparatory spray material inlet of ash storage room through the form valve, and the ash output hole of said ash storage room is communicated with the ash inlet of spiral dust unloadnig apparatus through a hose connector; The ash output hole of said spiral dust unloadnig apparatus is communicated with the ash inlet that connects grey tank car through No. two hose connectors; The sidewall of ash storage room has blast inlet and preparatory spout, and said blast inlet is oppositely arranged with preparatory spout; The air outlet of compress wind pipeline is communicated with the blast inlet of ash storage room, and the blast inlet of compress wind pipeline is the compress wind inlet; The in advance preparatory spray material inlet on jet pipe road and the preparatory spout connection of ash storage room, the preparatory spray material outlet on preparatory jet pipe road is communicated with the preparatory spray material inlet of coke oven, and butterfly valve is arranged between ash storage room and the hose connector, and spraying material in advance is coke powder.
A kind of coke oven ground station for dust removal based on said apparatus sprays method in advance, and its method is:
When coke oven is worked; The coke powder that coke oven is produced is sent into and is put grey storehouse, and said coke powder gets in the ash storage room, in this process through putting grey storehouse; Adopt compress wind will get into coke powder in the ash storage room through being blown in the control of dust pipeline the preparatory spray of realization coke oven ground station for dust removal in the preparatory jet pipe road.
In the preparatory spray process of coke oven ground station for dust removal, open butterfly valve, coke powder is got into through the spiral dust unloadnig apparatus connect in the grey tank car.
Beneficial effect: the present invention cancels the independent spray in advance of peripheral hardware storehouse, terrestrial station coke powder recovery bin bottom is advanced to connect install preparatory spraying equipment additional, and recovery bin and preparatory spray storehouse are united two into one, and does not therefore need again preparatory spray storehouse to be incubated processing, and the process of spraying in advance is not subjected to extraneous thermal effect; Simultaneously, the present invention adopts coke powder as spraying material in advance, and the coke powder prevented from caking sprays the influence that process is not subjected to spray in advance material in advance; Preparatory spray of the present invention is effective.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Embodiment one, combination Fig. 1 illustrate this embodiment; A kind of coke oven ground station for dust removal sprays system in advance; It comprises and connects grey tank car 8; It comprises puts grey storehouse 1, form valve 2, compress wind pipeline 3, butterfly valve 4, hose connector 5, spiral dust unloadnig apparatus 6, No. two hose connectors 7, ash storage room 9 and jet pipe road 11 in advance; The preparatory spray material outlet of putting grey storehouse 1 is communicated with the preparatory spray material inlet of ash storage room 9 through form valve 2, and the ash output hole of said ash storage room 9 is communicated with the ash inlet of spiral dust unloadnig apparatus 6 through a hose connector 5; The ash output hole of spiral dust unloadnig apparatus 6 is communicated with the ash inlet that connects grey tank car 8 through No. two hose connectors 7; The sidewall of ash storage room 9 has blast inlet and preparatory spout, and said blast inlet is oppositely arranged with preparatory spout; The air outlet of compress wind pipeline 3 is communicated with the blast inlet of ash storage room 9, and the blast inlet of compress wind pipeline 3 is the compress wind inlet; The in advance preparatory spray material inlet on jet pipe road 11 and the preparatory spout connection of ash storage room 9, the preparatory spray material outlet on preparatory jet pipe road 11 is communicated with the preparatory spray material inlet of coke oven, and butterfly valve 4 is arranged between ash storage room 9 and the hose connector 5, and spraying material in advance is coke powder.
