Description
Technical field:
The utility model relates to the coke oven dust system in the coking production, is specifically related to the coke oven coal-charging dust arrester.
Background technology:
The smoke discharge amount of coalingging of coal chemical enterprise accounts for sizable ratio in the toxic emission total amount.In the existing dust collection for charging technology, the technology that dedusting earth station handles the flue gas of coalingging is comparatively advanced.The dedusting earth station system comprises smoke-guiding car, flue gas switching valve, concetrated pipe, flue dust pretreatment unit, sack cleaner, ventilation blower, pre-spray equipment etc., and the problem of existence is: ventilation blower turns round always, and power consumption is big; Raw and auxiliary material consumption such as pre-spraying powder, dust settling pocket are big; Raw coke oven gas when coalingging directly effluxes through the spraying dedusting, and loss partization product is uneconomical; Equipment has high input, the maintenance cost height.
The utility model content:
The purpose of this utility model provides a kind of minimizing power consumption, increaseization product, increases gas yield, reduces the coal charging and dust removing device of operating cost, good dedusting effect.
Coke oven coal loading dedust system of the present utility model comprises charging car, smoke-guiding car, flue gas joint sleeve, tedge, bridge tube, discharge, ammoniacal liquor sprinkling system.The flue gas joint sleeve is arranged at smoke-guiding car top, and its top is connected in smoke-guiding car, does not hold at the smoke-guiding car guide pin bushing to dock with carbonization chamber tedge top during with the contraposition of carbonization chamber dedusting hole; The ammoniacal liquor sprinkling system comprises high pressure aqua ammonia sprinkling system, low pressure ammoniacal liquor sprinkling system; The ammoniacal liquor spray point is located at the bridge tube place, is provided with switching valve between the high and low pressure ammoniacal liquor sprinkling system.
The high pressure aqua ammonia sprinkling system comprises aqueous ammonia pump of high pressure, high pressure aqua ammonia pipeline, corresponding distribution system, automatic frequency-conversion pressure regulator.
Seal closure is established in the charging car front.
The dedusting port lid on carbonization chamber top is a manhole cover.
The utility model is provided with the flue gas joint sleeve on smoke-guiding car top, has increased the high pressure aqua ammonia sprinkling system, has removed a series of equipment of ground station for dust removal from, and equipment drops into low, and maintenance cost is low, does not need to consume pre-spraying powder, dust settling pocket etc.; The big problem of power consumption that does not have the continuous running of ventilation blower and cause; Suction by high pressure aqua ammonia, the raw coke oven gas part of coalingging enters discharge through smoke-guiding car, flue gas joint sleeve, the tedge of the carbonization chamber of coalingging, bridge tube, part directly imports with the carbonization chamber of coalingging by smoke-guiding car is separated by in one the carbonization chamber, suction by high pressure aqua ammonia, enter discharge through tedge, bridge tube, finally fully reclaimed in the gas purification workshop, the change product of generation is many, purified gas output height has reduced enterprise's discharge amount of exhaust gas.Seal closure before the charging car and dedusting manhole cover the coaling leakage of raw coke oven gas of further minimizing is set.
Description of drawings:
Fig. 1 is a dust arrester structural representation of the present utility model.
Fig. 2 is an ammoniacal liquor sprinkling system structural representation.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1,11,12,13 is carbonization chamber, and 2 is the combustion chamber, and 3 is smoke-guiding car, and 4 is the flue gas joint sleeve, and 5 is tedge, and 6 is bridge tube, and 7 is discharge, and 8 is the ammoniacal liquor spray point.Flue gas joint sleeve 4 is located at smoke-guiding car top, and top is communicated in smoke-guiding car, does not hold along with smoke-guiding car 3 docks with tedge 5 with the guide pin bushing contraposition of carbonization chamber.
As shown in Figure 2, the ammoniacal liquor sprinkling system in this dust pelletizing system comprises high pressure aqua ammonia sprinkling system, low pressure ammoniacal liquor sprinkling system, triple valve 9.The high pressure aqua ammonia sprinkling system comprises aqueous ammonia pump of high pressure 10, high pressure aqua ammonia pipeline 11, corresponding distribution system 12, automatic frequency-conversion pressure regulator 13, high pressure ammonia water valve 14.Low pressure ammoniacal liquor sprinkling system comprises low pressure ammonia water pipe 15, low pressure ammoniacal liquor valve 16.
17 are the dedusting port lid.
In the high-temperature coking operation, by low pressure ammoniacal liquor sprinkling the carrying out work that cools of waste flue gas.When coalingging operation, switch by triple valve 9, change the sprinkling of low pressure ammoniacal liquor into the high pressure aqua ammonia sprinkling and realize smokelessly coalingging.Coaling with carbonization chamber 11 and to be operating as example explanation present embodiment dust collection for charging process:
After side coal car and carbonization chamber 11 contrapositions, the operation of coalingging, this moment, furnace roof smoke-guiding car 3 guide pin bushings finished with dedusting hole 17 contrapositions of carbonization chamber 11 and carbonization chamber 13, and flue gas joint sleeve 4 also docks with the tedge 5 of carbonization chamber 11 and finishes.The signal of coalingging of side coal car reaches the ammoniacal liquor sprinkling system, switching by triple valve 9, ammoniacal liquor spray point 8 is sprayed by low pressure ammoniacal liquor automatically and is converted to the high pressure aqua ammonia sprinkling, the flue gas of coalingging of carbonization chamber 11 enters flue gas joint sleeve 4 under the powerful suction force of high pressure aqua ammonia, enter discharge 7 by tedge 5 tops, bridge tube 6, lead to the gas purification workshop by outlet 18.The flue gas of coalingging of carbonization chamber 13 enters discharge by tedge, bridge tube under the powerful suction force of high pressure aqua ammonia, enter the gas purification workshop at last and handle.The raw coke oven gas of coalingging that all pump drainages come out is handled obtaining product, purified gas in the gas purification workshop.
After carbonization chamber 11 was coaling and finished, triple valve switched, and raw coke oven gas is carried out low pressure ammoniacal liquor spray, and carried out the high-temperature coking process.
For the minimizing smoke spillage of coalingging, add seal closure in side coal car front.
Be to increase the sealing of dedusting port lid, improve the smokeless rate of furnace roof, prevent to lead sucking cold air in the cigarette operation and cause the gas explosion accident takes place in the carbonization chamber, manhole covers are adopted in dedusting hole 17.
