Abstract
A hyperoxic gas direct reclaimer of a tamping coke oven and a reclaiming technology are disclosed. The reclaimer comprises a coal-charging car and a charring chamber, which is characterized in that the gas collecting devices are arranged on the pusher side and the coke side on the top portion of the charring chamber (9), high-pressure ammonia injectors (6) are arranged in the gas collecting devices, and a sealing door device is installed on the front end of the coal-charging car (1). The reclaiming technology comprises opening the mouth of the charring chamber (9), starting the piston rod (12) of the coal-charging car (1) to push the sealing door (3) to seal the coal inlet (10) of the charring chamber (10), pushing briquette (2) into the charring chamber (9) from the mount of pusher side to generate partial high-negative-pressure region in the inner portion of bridge pipes (5) on the pusher side and the coke side, and plugging the mouth of the charring chamber (9) with the furnace door when the briquette totally enters into the charring chamber (9). The device overcomes the restricted aspect that raw gas which is transgressed has high oxygen content when charging coal on the side of the tamping coke oven, which can not enter into the gas collecting pipes, directly reclaim raw gas with high oxygen content which is transgresses, reduces cost and largely increases economic effects.
Description
Technical field
The present invention relates to the direct retrieving arrangement of a kind of tamping coke-oven high-oxygen gas and reclaim technology, belong to coke oven with utility appliance and production technique field.
Background technology
China's tamping coking oven side filling coal Technology, the widespread usage dust-removing vehicle.Raw gas and dust that loss in the process of coalingging is gone out suck the combustion chamber, and the Venturi scrubber of waste gas after burning on car enters atmosphere after the dust in the waste gas is washed.The deficiency of this technology is: environment is also had in varying degrees pollute, it also is a kind of great waste that maintenance cost height, the electric energy of wasting water, the raw gas of overflowing in the process of coalingging are all burnt.
Summary of the invention
Technical problem to be solved by this invention is in order to overcome above-mentioned defective, the direct retrieving arrangement of a kind of tamping coke-oven high-oxygen gas that improves the coke chemicals rate of recovery and reduce cost is provided and utilizes the simple and easy to do recovery technology of this retrieving arrangement.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: the direct retrieving arrangement of this tamping coke-oven high-oxygen gas, comprise coal charger and coking chamber, it is characterized in that: the top pusher side and the coke side place of coking chamber all are provided with gas extractor, establish the high pressure aqua ammonia shower nozzle in the gas extractor, the front end of coal charger is installed the hermatic door device.
Gas extractor comprises upcast, bridge tube, effuser, and a side of upcast connects bridge tube, and bridge tube connects effuser, the high pressure aqua ammonia shower nozzle is installed in the bridge tube, the hermatic door device comprises oil cylinder, hermatic door, piston rod, and oil cylinder is installed in the front end of coal charger, and in-oil cylinder piston rod connects hermatic door.
The hermatic door external diameter is greater than the external diameter of coking chamber, and internal diameter is slightly larger than coal inlet.
Effuser is spherical, and bridge tube is a bending.
The recovery technology of the direct retrieving arrangement of tamping coke-oven high-oxygen gas is characterized in that:
(1) open the fire door of coking chamber, start the Hydraulic Station on the coal charger, in-oil cylinder piston rod promotes the coal inlet that hermatic door seals up coking chamber;
(2) briquette is advanced coking chamber from coal inlet, open the high pressure aqua ammonia shower nozzle of machine, burnt both sides,, make high-oxygen gas enter effuser through upcast, bridge tube in machine, the inner local high negative pressure district that produces of burnt both sides bridge tube;
(3) after briquette all enters coking chamber, piston rod drives the hermatic door retraction, then with the coal inlet of fire door contraposition again at coking chamber, and the high pressure aqua ammonia shower nozzle of closure plane, burnt both sides.
Negative pressure in the machine, coke side bridge tube guarantees the speed that its suction velocity raw gas when coalingging produces.
Before coalingging, seal up the coking chamber coal inlet earlier, assurance coaling in the process air not by or bottom line suck in the coking chamber, make the oxygen content of crude gas of overflowing when coalingging drop to bottom line, to prevent that pusher side from because of the negative pressure that high pressure aqua ammonia produces sucks effuser to air by the briquette upper space, causing coal gas to contain oxygen and exceeding standard.The effect of the high pressure aqua ammonia shower nozzle of pusher side and coke side is to make to produce local high negative pressure in the bridge tube of pusher side and coke side, makes high-oxygen gas that briquette produces in coking chamber suck effuser by the upcast of pusher side and coke side.Use machine, coke side double collecting main structure, the raw gas that produces when coalingging with assurance import machine, coke side effuser from coking chamber machine, burnt both sides smoothly.The high pressure aqua ammonia shower nozzle guarantees that high-oxygen gas sucks the speed of the speed of effuser above the generation of raw gas when coalingging cake, prevents that coal gas is excessive from coal inlet.
The beneficial effect that compared with prior art the present invention had is: direct retrieving arrangement of tamping coke-oven high-oxygen gas of the present invention and recovery technology, break through the forbidden zone of " tamping coking oven side filling coal loss oxygen content of crude gas height; can not enter collecting pipe ", the hyperoxia raw gas of overflowing in the process of directly will coalingging reclaims, improved economic benefit greatly, ban dust-removing vehicle and auxiliary facility, reduced various cost expenditures, improved the rate of recovery of coke chemicals.After testing, coal gas contains oxygen all between 0.4%-0.6%, meets the standard that national coal gas contains oxygen＜1% fully.
