Abstract

The utility model relates to an auxiliary smoke guiding device used for shunting waste gas and reducing the leakage of the waste gas when a coke oven loads coal. The utility model is characterized in that a water sealing sheath layer and a water sealing cover layer of a water sealing type smoke guide seat are sealed; the utility model uses a lever type opening structure; a smoke guide pipe is hung on a coaling vehicle, and the smoke guide pipe and a coaling guide sleeve synchronously ascend and land; when coals are loaded, the smoke guide pipe drops in the smoke guide seat, and the smoke guide pipe is pressed on a purpose-made short arm of a water sealing sheath; with the falling of the smoke guide pipe, a water sealing cover is turned to open; the water sealing sheath falls to close when the smoke guide pipe ascends; when the water sealing sheath is opened, a coaling carbonization chamber is communicated with the adjacent coking late carbonization chamber; by the jet and suction of high-pressure ammonia water, the waste gas is divided into two ways to get into a gas collecting pipe so that the function of a double-collecting pipe is achieved, resource can be recovered, and the gas quality is improved. The device has the advantages that the investment is less, the operation is safe and convenient, the utility model is suitable for a top loading coke oven, and the utility model is suitable for the side loading coke oven.

Description

Hanging-Style Smoke Guider

The utility model is a kind of smoke guide device that can hang when being used for coke oven coal-charging on coal charger.

During the coke oven coal-charging operation, coal charge moisture, adsorbed gas and part fugitive constituent sharply gasify under coking chamber high temperature and separate out, and the raw gas (containing carcinogens BaP) that produces elevated pressures is carried the particulate coal dust secretly from coal filling hole and poorly sealed releasing, and smolders and catches fire.Damage equipment not only, waste resource be contaminate environment seriously also, and harm operator's health becomes big source of pollution and the carcinogenic arch-criminal that coke oven is produced.

According to reports, in the coke oven production about 70% the thing that diffuses to be that coking chamber enters when coalingging atmospheric.As seen administer key that coke oven pollutes and be and solve leaking of flue dust when coalingging.At present the method that adopts has: one, take out combustion method outward, promptly efflux after with blower fan flue dust suction one ad hoc combustion chambers burn in coal filling hole place being handled.Two, interior suction method, as adopting double collecting main, spray with high pressure aqua ammonia at upcast place, mechanical coke both sides and to enter recovery system again after attracting raw gas sucked two effusers respectively.Combustion method investment is huge, power consumption is high, regular job expense and maintenance workload are big, flue dust is burnt the waste of being not only resource, and can constitute secondary pollution.Though the investment of double collecting main method is few than the former, but still in millions of levels, dust directly enters follow-up system, and ammonia volume is big, increases for the follow-up system treatment capacity, and has influenced the coke chemicals quality.

The utility model is a kind of novel smoke guide device that designs at above-mentioned deficiency.

The utility model relates to a kind of coke oven coal-charging smoke guide detector.Comprise and lead smoke pipe seat 1, lead smoke pipe 4, hoisting appliance 7, it is characterized in that: fixedly water seal cover 2,2 unlatchings of water seal cover are lever to lead in the smoke pipe seat cylinder ear seat 9 usefulness bearing pins 10, hang ball face sealing lid 3 in the water seal cover 2, U-shaped is led smoke pipe 4 and is hung the position of leading smoke pipe seat 1 in the coal charger correspondence.

This device has the following advantages

1, device is simple, and less investment, power consumption are few, and fabrication and installation are convenient.

2, since operation with coaling synchronously, so it is convenient, adopt sealing structure for water, the switching of smoke guiding cover lid is all carried out under water seal is isolated, so safe and reliable, explode and break through the water seal pressure release even the oxygen height takes place, unlikelyly cause equipment and fatal accident.

3, can realize that raw gas reclaims, improve its quality product, certain economic benefits is arranged.

4, owing to realize raw gas and effectively shunt, be easy to sealing, can realize smokelessly coalingging, reduce and pollute and receive certain environmental benefit.

Below in conjunction with accompanying drawing this utility model is described in detail:

This device (seeing accompanying drawing 1) is led smoke pipe seat 1 by hydrolock and is led three parts such as smoke pipe 4 hoisting appliances 7 grades and form.Lead smoke pipe seat 1 and be located at the coke furnace carbonization chamber coke side.It is the same with the upcast setting to insert the coking chamber top.And configuration upper and lower conduit road, the envelope that supplies water adds the usefulness of water overflow continuously.Water seal cover 2 is a lever, and armed lever is fixed on the interior cylinder ear seat 9 with axle 10.Hang the hard sealing cover 3 of a sphere in the cover to realize doing wet dual seal.And by the coking chamber spacing U-shaped is set and leads smoke pipe 4 and hang the position of leading the smoke pipe seat in the coal charger correspondence, walk displacement with garage, promote with lifting mechanism 7 controls, during work with coaling the guide pin bushing synchronization action.Leading smoke pipe 4 falls into and leads cigarette seat water sealed tank 2 and be pressed on the armed lever of water seal cover, by lever principle, the related hard sealing cover of water seal cover is opened, by leading smoke pipe two coking chambers are communicated with, be isolated from the outside with the water seal that forms, the raw gas in the coking chamber of coalingging like this import pressure lower, coking is ripe or maturescent coking chamber top passageway, spray by two coking chamber upcast bridge tube places high pressure aqua ammonias to attract to divide two-way to enter effuser.By the water-gas reaction that part coal dust in the raw gas of adjacent coking chamber top passageway falls and carries out with the steam and the vehement hotbed of carbon, generation CO and H ₂Thereby, the effective constituent of raising raw gas.Because raw gas shunting, the stifled deadening power of the logistics of being coaling influence minimizing, thereby reduce coaling coking chamber and coal port place pressure, help the coaling gear sealing, coaling finish after, the lifting gear action is led smoke pipe and is mentioned, and manhole cover falls by deadweight, fall into water sealed tank and form water seal and close, be isolated from the outside.Reclaim thereby reach raw gas, reduce the purpose of leaking.

Device for carrying out said place coke oven is limit owing to coal tower span, lead smoke pipe and can not enter the coal tower in company with coal charger, so platform is provided with one and specially has a buffering between stove, the smoke pipe placement table (Fig. 2) of leading every the magnetic function is led the electro-magnet 5 of smoke pipe by the hoisting appliance bottom and is inhaled and be integral, control with electrical contact, when advancing the coal tower, coal charger cuts off the power supply automatically in the placement table position except that magnetic, to lead smoke pipe stays on the placement table, automatically send electric excitation to pick up in the position of placement table to lead smoke pipe and walk to the coking chamber of to coaling when coal charger installs the coal tower that produces coal, lead smoke pipe and fall by hoisting appliance in company with the guide pin bushing of coalingging, promote action, finish and lead the cigarette operation.
