Coke oven coke oven uprising tube is in the burner smoke dust-removal system of pusher side
The utility model relates to a kind of burner smoke dust-removal system, and specifically a kind of coke oven coke oven uprising tube belongs to coke oven coal-charging gas cleaning dedusting technology field in the burner smoke dust-removal system of pusher side.
Coke oven dust is a new technical barrier, and tamping coke furnace produces the flue dust of a large amount of raw gas, coal tar and cotton-shaped viscosity when coalingging, and wherein pusher side burner flue gas is the most difficult.When particularly using the ammoniacal liquor side to lead device, owing to control coking chamber intake air negative pressure, to reach the oxygen level in the control coal gas, so the burner smoke amount is larger.Mainly containing pest in the coal-charging smoke is coal dust, raw gas, tar cigarette, also contains simultaneously BSO and BaP, and contaminate environment is detrimental to health.Treatment process commonly used is: one, input smoke elimination car burning carrying out washing treatment; Two, the input smoke guiding bogie imports the ground station for dust removal processing.But these two kinds of methods have certain shortcoming: the smoke elimination car is processed very difficult up to standard, and ground station for dust removal is processed because fed distance is too far away, causes resistance excessive.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide the burner smoke dust-removal system of a kind of coke oven coke oven uprising tube at pusher side, the pusher side burner flue gas of tamping coke furnace is collected by the mobile set dust hood that is installed on the coal charger, through belt trolley, ventilation slot, importing is arranged on ground sack cleaner and purifies, processes.It is a kind of novel, simply and easily flue gas conducting cleaning apparatus.
The utility model technical solution problem adopts following technical scheme:
Coke oven coke oven uprising tube is in the burner smoke dust-removal system of pusher side, and it comprises:
Be located at the fixed set dust hood on coke furnace carbonization chamber top, be provided with the mobile set dust hood that can dock with described fixed set dust hood at coal charger, described mobile set dust hood is by the cleaning shaft on the described coal charger and belt trolley and ventilation slot connection thereof, described ventilation slot is communicated with coke absorbing device, sack cleaner by the road successively, and the end of described sack cleaner is communicated with blower fan.
On the pipeline between described adsorption unit and the described sack cleaner, also be provided with very valve and pre-spray system, described very valve, its operation acts interrelates with the signal that discharges of the coke/coaling.Signal passes and comes, and to running up, very valve cuts out blower fan by low speed.To guarantee that coke oven discharges of the coke/the necessary suction of dust collection for charging.The signal ended of the discharging of the coke, the blower fan low-speed running, very valve is opened.Because blower fan still in running, is balance blower fan external and internal pressure, prevent that blower fan is inner because serious negative pressure causes the casing distortion, and very valve is opened, the air that blower fan is inhaled can enter from valve, with balance blower fan system external and internal pressure.Described pre-spray system: the blower fan of coalingging running, the flue dust of taking out mainly contain the high temperature raw gas that produces of coalingging, fine breeze etc.The raw gas cooling, the materials such as tar are wherein become by gaseous state close-burning solid.For preventing that these viscous substances are bonded on the cloth bag, damage cloth bag or reduce the cloth bag life-span, before the beginning of coalingging, pre-spraying is jetted first one deck ash (mainly being coke powder) on the cloth bag of dust collection for charging.After the end of coalingging, the blowback action is easy to the material that filters on the cloth bag is blown down.
The bottom of described sack cleaner is provided with ash bucket and is located at the unloading valve of ash bucket bottom.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model is installed a fixed set dust hood on coke furnace carbonization chamber top, at coal charger a mobile cover is installed, when coalingging, coal charger docks with formal dress coal carbonization chamber, at this moment the fixed set dust hood also just in time docks with the mobile set dust hood, and the flue gas of collection imports in the ground station for dust removal through belt trolley and ventilator trunk, carries out gas cleaning, flue gas both can qualified discharge, can greatly reduce resistance again.Remedy smoke guiding bogie, ammoniacal liquor side and lead the deficiency that burner smoke is processed, can carry out the dedusting of independent burner flue gas.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Number in the figure: 1 fixed set dust hood, 2 mobile set dust hoods, 3 belt trolleys, 4 ventilation slots, 5 coke absorbing devices, 6 unusual valves, 7 pre-spray systems, 8 sack cleaners, 9 unloading valves, 10 blower fans.
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment: referring to Fig. 1, the coke oven coke oven uprising tube of present embodiment is in the burner smoke dust-removal system of pusher side, on coke furnace carbonization chamber top fixed set dust hood 1 to be set, at coal charger mobile set dust hood 2 is set, mobile set dust hood 2 links to each other with belt trolley 3 on coal charger by the cleaning shaft on the coal charger, flue gas enters coke absorbing device 5 by ventilation slot 4, enter again sack cleaner 8 after the purification, sack cleaner 8 back are communicated with blower fan 10, fan outlet is communicated with chimney, technology routinely, on the pipeline between coke absorbing device 5 and the sack cleaner, also be provided with very valve 6 and pre-spray system 7, be provided with ash bucket in the bottom of sack cleaner 8 and be located at the unloading valve 9 of ash bucket bottom.
In conjunction with Fig. 1, tamping coke furnace is in the process of coalingging, the a large amount of flue gas slave wing furnace doors that produce overflow, because flue gas has certain temperature, hot flue gas rises and enters fixed set dust hood 1, when coalingging, coal charger travels to the formal dress coking chamber, realize that fixed set dust hood 1 docks with mobile set dust hood 2, flue gas flow is: flue gas is through mobile set dust hood 2, the control of dust main, belt trolley 3 and ventilation slot 4, coke absorbing device 5, sack cleaner 8, emptying through blower fan 10, very valve 6, pre-spray system 7 and sack cleaner 8 unload routinely technical operation of grey dedusting, by pulse valve blowing, dust falls into ash bucket, unload ash through unloading valve 9, the utility model is applicable to the burner smoke dedusting of tamping coke furnace.Can remedy smoke guiding bogie, ammoniacal liquor side and lead the deficiency that burner smoke is processed, can carry out the dedusting of independent burner flue gas.
