Description
Technical field
The design is metallurgy industry coal tar quench system, is mainly a kind of tunnel type zero release electronic program coke quencher, belongs to Internet of Things using environment-friendly technical field.
Background technology
In current metallurgy industry process of coking, very big at the extinguishing technique exhaust emission having, basic technology is by spray water cooling quenching, also has the obnoxious flavoures such as sulfurous gas, breeze dust, carbonic acid gas when quenching by high temperature in the discharge of steam being caused.
Aspect current topsoil environmental requirement improvement, it is being a great difficult problem, the quenching of the spray water of metallurgy industry cooling at present adopts conventional wet method low discharge, the quenching of lower velocity splashing type mode, too little compared with the speed being absorbed by coke with coke quenching water for water speed of quenching nozzle, being sprayed onto the water major part on coke in quenching car is absorbed by the coke of car body top, only have a small amount of water to flow to bottom, use for many years to observe and find that conventional wet quenching mainly contains following defect: 1, reduce coke moisture, the quenching time must be shortened, but will cause the coke quenching of quenching car bottom insufficient, there is red Jiao, transport in burnt process and scorch belt, avoid red Jiao, must extend the quenching time, top coke moisture is excessive like this, causes coke moisture inhomogeneous, and 2, the quantity of steam that produces in quenching process is large, needs rate of water make-up large, waste water source, 3, generation free-and-easy thing contaminate environment energetically in quenching process.4, spray hole very easily stops up, and affects quenching effect, need be regularly clear and coherent, and bring inconvenience to normal production.
Coking industry is the important auxiliary industry of Iron And Steel Industry, through years development, still exists layout unreasonable, produce and disperse, and disorderly competition, the problem that concentration degree is low, coking production environmental pollution and the wasting of resources are still very serious.In recent years, more domestic enterprises blindly enhance production capacities, and occur that supply exceed demand in domestic market, the situation of world market finite capacity.Existing coal chemical enterprise, owing to being subject to the strict demand of environmental protection and the restriction of " coking industry entry criteria ", has been taked more advanced Pollution abatement measure.But still have some enterprises can not meet pollutent standard and total amount emission request, cause the environmental pollution of Chan Jiao district serious, therefore, the processing condition of formulating strict pollutant emission standard are to control the most effective means of pollutant emission.
Documents: in static-bed coke quenching producer 201110251706 specification sheetss, the described full water jacket quenching producer of [0012] section comprises full water jacket boiler and pipeline, the drum that variable valve connects, be arranged on the charging mouth of pipe at body of heater top, vent valve, device and pipeline are washed one's hair in the water quenching spray that is arranged on stove internal upper part, the water tank that variable valve connects, be arranged on tower gasification nozzle and the pipeline of bottom in stove, the step-down drum that variable valve connects, be arranged on the drainage conduit of bottom of furnace body, red burnt device for detecting temperature composition, wherein the spacer of statement and coke quencher's spacer of the design are diverse functional structures.
Documents: a kind of coke quenching auxiliary 201020585375.6 claim 2. coke quenching auxiliary according to claim 1, it is characterized in that, described quenching stove is closed structure, and specification sheets [0011] section quenching stove 2 can adopt closed structure, first by the semicoke of red heat state (the now temperature of the semicoke of red heat state, do not state out sealing method and structural principle at all, be difficult to allow the those of ordinary skill in this field understand, how airtight under 600 ℃～900 ℃ such left and right hot conditionss.
This tunnel type zero release electronic program coke quencher, the design of innovation concept is that the chuck that coke quencher adopts is full of water equally, effect is in order to reclaim the high-temperature residual heat in quenching process, air door sealing, the haze that isolation coke quencher imports and exports leaks, can allow the high-temperature gas producing in quenching process enter recovery system by extraction pipe, energy-saving and emission-reduction and regeneration added value.
Summary of the invention
One tunnel type zero release electronic program coke quencher, adopt sulfurous gas in air door sealing quenching process, the high-temperature gas that carbon monoxide dust etc. mix, the red heat of 1000 ℃ ± 50 ℃ that pit kiln is produced reclaims heat by the recirculated water heat absorption in spacer and recycles, can be used for cogeneration, gas leakage in air door sealing quenching process, the powerful air-flow of being discharged by strength gas port is connect and draws processing by extraction pipe, can reach zero release completely, the environmental pollution and the energy dissipation that cause because of blowing air discharge and slag emission are solved in existing technique, solved in dry quenching(of coke) process because of coke burning and part noxious gas emission simultaneously, save the energy, protect environment, adopt tunnel type zero release electronic program coke quencher to avoid the operation of the dust that recycle gas carries secretly, the wearing and tearing of equipment are reduced.
The design adopts nature landing discharge system, and machinery-free extruding, has reduced the breakage of coke, has saved electric energy.Red burnt water after cooling extinguishes, sealing dedusting through air-flow, the dust producing in recycle-water quenching process and quenching water, reclaiming the gas delivery purifying producing in quenching process is that water-gas is created added value, reduce that the dust that produces in water law quenching process and harmful organic substance enter atmosphere and the environmental pollution that causes, reduce water consumption, saved water resources.
