Description
Technical field
The invention belongs to Low Water Consumption Coke Quenching field, particularly a kind of Low Water Consumption Coke Quenching and residual heat using device thereof.
Background technology
At present, both at home and abroad the coke quenching method of coke oven has two kinds of CDQ and wet quenchings.CDQ is a kind of coke quenching method with cooling red Jiao of low temperature inert gas.Dry coke quenching energy-conservation, improve aspect coke quality and be better than coke wet quenching, but its floor space is large, device structure is complicated, manufacture difficulty is large, maintenance cost is high, investment is large.Wet quenching is that water sprays red Jiao, comprises Low Water Consumption Coke Quenching, coke stabilized quenching etc., and red Jiao is down to below 100 degree, and the steam of generation is directly discharged into atmosphere.Its feature is that technique is simple, reduced investment, and operation, easy maintenance, shortcoming is: the red burnt sensible heat that 1. accounts for whole coking heat consumption 3035 % does not effectively utilize; 2. water resources consumption is many; 3. red anxious acute cooling, reduce coke quality; 4. the entrainment with steam that quenching produces has pollution, Korrosionsmedium and dust, enters not only environmental pollution of atmosphere, but a kind of waste of heat energy.
Summary of the invention
The technical problem solving:
CDQ floor space is large, device structure is complicated, manufacture difficulty is large, maintenance cost is high, investment is large; The red burnt sensible heat utilization rate of wet quenching is low, and water resources consumption is many, and atmosphere pollution is serious.

Described quenching tower below is covered with guide rail, is equipped with coke quenching cart on guide rail.
The oblique bottom of described coke quenching cart is provided with delivery port and coke outlet.
Described high-pressure water nozzle evenly gathers directly over coke collection quarrel.
Beneficial effect:
1, the present invention saves quenching water, and quenching is effective, and atmosphere pollution is low, and thermal waste is few;
2, floor space of the present invention is little, and device structure is simple, and investment cost is little, and convenient transportation, energy continuous operation, good economy performance.
Accompanying drawing explanation:
Accompanying drawing 1 is structural representation of the present invention;
1. coke quenching cart 2. coke collection bucket 3. high-pressure water nozzle 4. dust extractor 5. quenching tower 6. high pressure tank 7. secondary filter 8. purifier 9. superheater 10. condensing turbine 11. generator 12. condenser 13. steam accumulator 14. water circulating pump 15. control valve 16. guide rail 17. delivery port 18. coke outlet 19. waste heat boilers.
The specific embodiment
Below in conjunction with accompanying drawing 1, the present invention is further illustrated.
The present invention includes coke quenching cart 1, coke collection bucket 2, high-pressure water nozzle 3, dust extractor 4, quenching tower 5, high pressure tank 6, secondary filter 7, purifier 8, superheater 9, condensing turbine 10, generator 11, condenser 12, steam accumulator 13, water circulating pump 14, control valve 15, guide rail 16, delivery port 17, coke outlet 18, waste heat boiler 19, wherein quenching tower 5 inside are provided with high-pressure water nozzle 3 and coke collection bucket 2, top is provided with dust extractor 4, top pipeline is through secondary filter 7, purifier 8 and waste heat boiler 19, steam accumulator 13 is connected, through superheater 9, connect condensing turbine 10 again, finally by crossing condenser 12, water circulating pump 14 is connected high pressure tank 6, high pressure tank 6 lower channel are connected with high-pressure water nozzle 3 through control valve 15.
Described quenching tower 5 belows are covered with guide rail 16, are equipped with coke quenching cart 1 on guide rail 16.
The described oblique bottom of coke quenching cart 1 is provided with delivery port 17 and coke outlet 18.
Described high-pressure water nozzle 3 evenly gathers directly over 2 mouthfuls of coke collection buckets.
Operation principle and process:
Coke quenching cart 1 is transported to below quenching tower 5 after filling high-temperature coke on guide rail, aligns with 2 mouthfuls of coke collection buckets, stablizes motionlessly, opens control valve 15, and the water inflow pipe in high pressure tank 6, through high-pressure water nozzle 3 ejections, starts Low Water Consumption Coke Quenching.High-temperature coke sprays through High-Pressure Water, make coke quenching water far faster than coke quenching water, be inhaled into the speed in coke button for water speed, to such an extent as to these a large amount of water that spray, when only some is from top to bottom by coke layer, be absorbed and fierce vaporization, all the other major parts flow through each coke charge charcoal until coke quenching cart 1 inclined floor, from delivery port, flow out, avoided coke quenching water to gather in car and flooded and soak into coke, cause coke moisture too high.Each layer in car, especially red-hot red Jiao in car bottom contacts fierce vaporization and a large amount of steam of instantaneous generation with coke quenching water, rely on its huge motive force to be touched from bottom to up and cooling coke, and make coke in a kind of " boiling " state, now coke collection bucket 2 can prevent that coke from jumping out outside car.
The entrainment with steam that quenching produces has pollution, Korrosionsmedium and dust, along with high temperature gas flow first carries out one-time dedusting through dust extractor 4, then enter quenching tower 5 top pipelines, through secondary filter 7 dedustings and purifier 8, purify toxic gas, enter waste heat boiler 19, the high-temperature vapor producing is stored in steam accumulator 13, then enters condensing turbine 10 through superheater 9, and drives generator 11 generatings.From condensing turbine 10 low temperature steam out, after condenser 12, the steam of the inside all condenses into water, then sends in high pressure tank 6 through water circulating pump 14, can be recycled.This device has avoided atmosphere pollution to utilize again waste heat, while convenient transportation, and energy continuous operation, good in economic efficiency.
