Description

A kind of coal oven dithio-gas take-up stand
Technical field
The utility model relates to a kind of new Type Coke Oven raw gas take-up stand, can smoothly raw gas in the coking chamber be imported effuser during production, can close water-sealed valve when the discharging of the coke rapidly and open upcast manhole cover, operational safety rapidly; Be particularly related to a kind of novel pit kiln raw gas take-up stand.
Background technology
Pit kiln both domestic and external all is through the natural gas gathering system at furnace roof the raw gas that coking chamber produces to be derived when producing; Spray cooling at the bridge tube place with ammoniacal liquor; Raw gas after the cooling is sent to follow-up workshop section together with cooled tar ammonia, and raw gas derives to pass through does not have the upcast of gradient take-up stand, bridge tube, valve body to get into effuser then; The socket joint of bridge tube and valve body is the water seal of simple U type; In the derivation process or in the stage of going into operation, during the ammoniacal liquor cold test,, the ammoniacal liquor refluence occurs through regular meeting and get into upcast because the upcast take-up stand is horizontally disposed, the situation that gets into coking chamber then is bigger to production operation harm.Because the socket joint of bridge tube and valve body is simple U type sealing structure for water, high pressure aqua ammonia can impact U type valve disc under spray regime, sealer in the valve disc is gone out the valve disc bell and spigot, needs artificial often repairing, influences environment, loses time, and brings labile factor to production.Switching upcast manhole cover and valve body water seal need manual work to open or mechanical linkage promotes to open, and often contraposition is inaccurate, brings hidden danger to production operation.
Summary of the invention
The purpose of the utility model provides a kind of coal oven dithio-gas take-up stand, and this device can effectively solve the ammoniacal liquor refluence and ammoniacal liquor impacts the defective of water-sealed valve valve disc, and can realize automatic controlled opening/closing upcast manhole cover and valve body water seal.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of coal oven dithio-gas take-up stand; Comprise the upcast manhole cover controller for opening and closing, upcast manhole cover, upcast take-up stand, cooling low pressure ammonia water spray device, high pressure aqua ammonia sparging unit, bridge tube, water-sealed valve valve body, water-sealed valve valve disc, water-sealed valve valve disc controller for opening and closing, the effuser that are installed in coke oven machine side or coke side; It is characterized in that; Described upcast take-up stand is the downward-sloping structure that ammoniacal liquor flows backwards that prevents, its both sides are connected with bridge tube, upcast water seal seat respectively.
Described bridge tube and water-sealed valve valve body junction are labyrinth bayonet joint structure.
Described upcast take-up stand inside is provided with lagging material.
Described upcast take-up stand is provided with cleaning and spies on device.
This device is applicable to tamping coke furnace or the raw gas derivation of top dress coke oven in the process of coalingging.
Compared with prior art, the utility model has the advantages that:
The raw gas that produces when this device can be produced coke oven smoothly imports effuser, and ammoniacal liquor refluence phenomenon can not take place; High pressure aqua ammonia can not take place yet impact U type valve disc, sealer in the valve disc is gone out the drawback of valve disc bell and spigot; Can realize the loaded down with trivial details work of automatic controlled opening/closing upcast manhole cover and valve body water seal, improve the automation of operation level; But have carrying out smoothly of advantage strong guarantee productions such as flexible operation, maintenance convenience, reasonable structural arrangement, energy-conservation and environment protecting be remarkable.

Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
See Fig. 1; A kind of coal oven dithio-gas take-up stand comprises coke oven furnace roof upcast manhole cover controller for opening and closing 1, upcast manhole cover 2, upcast water seal seat 3, anti-return upcast take-up stand 4, cooling low pressure ammonia water spray device 5, high pressure aqua ammonia sparging unit 6, cleans and spy on device 7, anti-current assault bridge pipe 8, water-sealed valve valve disc controller for opening and closing 9, anti-current shock valve body 10, water-sealed valve valve disc 11, effuser 12, anti-return upcast take-up stand 4 liner lagging materials 13.
Upcast manhole cover controller for opening and closing 1 can be installed in the coke oven furnace roof of coke oven machine side or coke side; Be used for controlling the unlatching of upcast manhole cover 2 and closing; Anti-return upcast take-up stand 4 is the downward-sloping structure that ammoniacal liquor flows backwards that prevents, its both sides are connected with anti-current assault bridge pipe 8, upcast water seal seat 3 respectively.Cooling low pressure ammonia water spray device 5, high pressure aqua ammonia sparging unit 6 and cleaning are installed on the anti-current assault bridge pipe 8 and spy on device 7.
Anti-current assault bridge pipe 8 is a labyrinth bayonet joint structure with water-sealed valve valve body 10 junctions, and this structure can solve the problem of sealer in the water-sealed valve valve disc 11 being gone out the valve disc bell and spigot.Keying, the anti-current shock valve body 10 of water-sealed valve valve disc controller for opening and closing 9 control water-sealed valve valve discs 11 connect effuser 12, and this device can effectively be accomplished the requirement of production technique.
The working process of this device is: coke oven coal-charging begins; Upcast manhole cover controller for opening and closing 1 is closed upcast manhole cover 2; Water-sealed valve valve disc controller for opening and closing 9 is opened water-sealed valve valve disc 11; Cooling low pressure ammonia water spray device 5 sprays, high pressure aqua ammonia sparging unit 6 high pressure are started working the end of coalingging.High pressure aqua ammonia sparging unit 6 transfers operating on low voltage to, and the raw gas that produces of coalingging gets into effuser 12 through anti-return upcast take-up stand 4, anti-current assault bridge pipe 8, anti-current shock valve body 10 smooth derivation; Water-sealed valve valve disc controller for opening and closing 9 is closed water-sealed valve valve disc 11 before the discharging of the coke, and cooling low pressure ammonia water spray device 5 sprays, high pressure aqua ammonia sparging unit 6 operating on low voltage, and upcast manhole cover controller for opening and closing 1 is opened upcast manhole cover 2, and wait is discharged of the coke.Accomplish a working cycle.
The utility model device is applicable to all tamping coke furnaces, pushes up and adorn coke oven, in the process of coalingging and in the normal productive process, derive the flue gas of coalingging smoothly, and the raw gas that produces in the completion production is derived normally.Solve the ammoniacal liquor refluence and got into upcast, got into the coking chamber problem then; And solved high pressure aqua ammonia and under spray regime, impact U type valve disc, sealer in the valve disc is gone out valve disc bell and spigot problem.
