Abstract
The invention relates to a method for drawing raw coal gas out of coke oven. A device used comprises a riser water seal cover opening and closing control device on a coke oven side or coke side, a riser water seal cover, a riser lead-out device, a cooled low-pressure ammonia water spraying device, a high-pressure ammonia water spraying device, a bridge tube, a water seal valve body, a water seal valve disk, a water seal valve disk opening and closing control device and a gas collecting tube, and is characterized in that: the method adopts a downward inclined riser lead-out device for preventing ammonia water from flowing back, and the two sides of the riser lead-out device are connected with the bridge tube and a riser water seal seat respectively. The device has the advantages that: raw coal gas generated in production in coke oven can be led into the gas collecting tube smoothly without returning ammonia water; the drawback that sealing material in the valve disk is washed out of the socket of the valve disk when the U-shaped valve disk is washed by high-pressure ammonia water is overcome; and the operation is flexible, the overhaul is convenient, the structural arrangement is reasonable, and the energy-saving and environment-protection effects are obvious, and the like.
Description
Technical field
The present invention relates to a kind of new Type Coke Oven raw gas deriving method, 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 gear.
Background technology
Pit kiln both domestic and external all is by 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 is derived will be through not having upcast take-up gear, bridge tube, the valve body of gradient to enter 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 enter upcast because the upcast take-up gear is horizontally disposed, the situation that enters 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 manually often to repair, and influences environment, loses time, and brings labile factor to production.Open and close the upcast manhole cover and the valve body water seal need manually be opened or mechanical linkage promotes to open, often contraposition is inaccurate, brings hidden danger to production operation.
Summary of the invention
The purpose of this invention is to provide a kind of coal oven dithio-gas deriving method, this method 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 achieving the above object, the present invention is achieved through the following technical solutions:
A kind of coal oven dithio-gas deriving method, the device that relates to comprises upcast manhole cover controller for opening and closing, upcast manhole cover, upcast take-up gear, cooling low pressure ammonia water spray device, high pressure aqua ammonia jet apparatus, 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 is installed in coke oven machine side or coke side, it is characterized in that, this method adopts downward-sloping structure to prevent the upcast take-up gear that ammoniacal liquor flows backwards, and described upcast take-up gear 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 gear inside is provided with lagging material.
Described upcast take-up gear is provided with cleaning and spies on device.
This method 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, advantage of the present invention is:
The raw gas that produces when this method 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
The present invention is described in detail below in conjunction with accompanying drawing.
See Fig. 1, a kind of coal oven dithio-gas deriving method, the device that relates to comprise 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 gear 4, cooling low pressure ammonia water spray device 5, high pressure aqua ammonia jet apparatus 6, clean 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 gear 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 gear 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 jet apparatus 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 finished the requirement of production technique.
