Abstract
A tamping coke oven hyperoxia gas direct recovery device includes a coal charging car and a coking chamber, which is characterized in that gas collecting devices are arranged on a turbine side and a coke side on top of the coking chamber (9). The gas collecting devices are equipped with high-pressure ammonia nozzles. The front end of the coal charging car (1) is equipped with a seal door device.
Description
Technical field
The utility model relates to the direct retrieving arrangement of a kind of tamping coke-oven high-oxygen gas, belongs to coke oven and uses the utility appliance 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.
The utility model content
Technical problem to be solved in the utility model is: in order to overcome above-mentioned defective, provide a kind of tamping coke-oven high-oxygen gas that improves the coke chemicals rate of recovery and reduce cost direct retrieving arrangement.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted 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, one side of upcast connects bridge tube, 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, hydraulic ram 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.
Coal charger is before coalingging, start Hydraulic Station earlier, in-oil cylinder piston rod promotes the coal inlet that hermatic door seals up coking chamber, 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 briquette top, causing coal gas to contain oxygen and exceeding standard.This moment, coal charger advanced coking chamber with briquette slave wing furnace mouth, open the high pressure aqua ammonia shower nozzle of machine, burnt both sides, under the effect of pusher side and coke side high pressure aqua ammonia shower nozzle, in the bridge tube of pusher side and coke side, produce local high negative pressure, make raw gas that briquette produces in coking chamber suck effuser by the upcast of pusher side and coke side.After briquette all entered coking chamber, piston rod drove the hermatic door retraction, with fire door the coal inlet of coking chamber was blocked, at this moment the high pressure aqua ammonia shower nozzle of closure plane, burnt both sides.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 the speed of raw gas suction effuser surpasses the speed that raw gas produces when coalingging cake, prevents that coal gas slave wing furnace mouth is excessive.
Compared with prior art the beneficial effect that the utility model had is: the direct retrieving arrangement of tamping coke-oven high-oxygen gas of the present utility model, the hyperoxia raw gas of overflowing in the process of directly will coalingging reclaims, improved economic benefit greatly, dust-removing vehicle and auxiliary facility have been banned, reduce 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.

Fig. 2 is the utility model oven door sealing synoptic diagram;
Fig. 3 is the A-A view of Fig. 2;
Fig. 4 is the B-B view of Fig. 3.
Among the figure: 1 coal charger, 2 briquettes, 3 hermatic doors, 4 effusers, 5 bridge tubes, 6 high pressure aqua ammonia shower nozzles, 7 upcasts, 8 T-valve, 9 coking chambers, 10 coal inlets, 11 oil cylinders, 12 piston rods.
Embodiment
As shown in Figure 1: the direct retrieving arrangement of tamping coke-oven high-oxygen gas, the top pusher side and the coke side place of coking chamber 9 all are provided with gas extractor, gas extractor is by upcast 7, bridge tube 5 and effuser 4, one side of upcast 7 connects bridge tube 5, bridge tube 5 connects effuser 4, high pressure aqua ammonia shower nozzle 6 is installed in the bridge tube 5 and connects T-valve 8 by pipeline, and effuser 4 is spherical, and bridge tube 5 is a bending.
Shown in Fig. 2-4: the hermatic door device comprises that oil cylinder 11, hermatic door 3,12, four hydraulic rams 11 of piston rod are installed in the front end of coal charger 1, and the piston rod 12 in the oil cylinder 11 connects hermatic door 3.Hermatic door 3 external diameters are greater than the external diameter of coking chamber 9, and internal diameter is slightly larger than coal inlet 10.
Working process is as follows:
Coal charger 1 is before coalingging, start Hydraulic Station earlier, piston rod 12 in the oil cylinder 11 promotes the coal inlet 10 that hermatic door 3 seals up coking chamber, assurance is 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 4 to air by briquette 2 upper spaces, causing coal gas to contain oxygen and exceeding standard.This moment, coal charger 1 advanced coking chamber 9 with briquette 2 from coal inlet 10, open the high pressure aqua ammonia shower nozzle 6 of machine, burnt both sides, under the effect of pusher side and coke side high pressure aqua ammonia shower nozzle 6, in the bridge tube 5 of pusher side and coke side, produce local high negative pressure, make raw gas that briquette 2 produces upcast 7 suction effusers 4 coking chamber 9 in by pusher side and coke side.After briquette 2 all entered coking chamber 9, piston rod 12 drove hermatic door 3 retractions, then fire door is blocked the coal inlet 10 of coking chamber 9, at this moment the high pressure aqua ammonia shower nozzle 6 of closure plane, burnt both sides.Use machine, burnt both sides double collecting main structure, the raw gas that produces when coalingging with assurance import in machine, the coke side effuser 4 from coking chamber 9 machines, burnt both sides smoothly.High pressure aqua ammonia shower nozzle 6 guarantees that the speed of raw gas suction effuser 4 surpasses the speed that raw gas produces when coalingging cake, prevents that coal gas slave wing furnace mouth is excessive.
