With the water sealing type guide sleeve device for charging coal of the utility model, no fume produced in the coal charging can be leaked out. The utility model has the advantages of less investment, convenient installation and simple operation. The water sealing type guide sleeve device for charging coal can be used to charge coal for all the top loading coke ovens.
Description
The utility model belongs to the feeder of coke furnace, is specially adapted to coke oven coal charging car sealing coal supply apparatus.
The coke oven of China more than 95% all is the top shove charge, the furnace roof coal charger generally all uses a movable guide pin bushing that the coal in the coal groove on the car is imported in the coking chamber stoke hole, this just cause raw gas, flue dust from the interface of guide pin bushing and stoke hole seat and movable guide pin bushing and fixedly the gap location between the coal elephant trunk leak in a large number so that smolder, burn with anger, damage equipment.Not only energy, resource are lost in vain, also serious contaminate environment.According to " one coking of modern steel industrial technology and coal gas refining " report coke oven coal-charging process gas 3-5m that leaks
3/ t coal, dust quantity 1.22kg/t coal contains the number of chemical material in the pollutent of external world's discharging, and wherein 3.4 1 benzopyrenes are to endanger very big carcinogenic substance.
The topsoil that coking in recent years causes has caused the great attention of countries in the world, reduces pollution, environment protection treating, realization is smokelessly coaling has been the common objective of coking enterprise.The improvement of coke oven smoke is because technical difficulty is big, investment is high, energy consumption is big, no matter domestic, all still be in the research exploratory stage abroad.Coking industry is generally held two kinds of viewpoints both at home and abroad at present, adopts two kinds of diverse ways:
A kind of viewpoint is " row ", adopts outer suction method, and the flue dust that produces in the time of promptly will coalingging with blower fan is from the special combustion chamber of guide pin bushing interface suction, ignition after washing efflux.
Another kind of viewpoint is " blocking up ", and suction method in adopting promptly attracts to produce negative pressure at the upcast place with high pressure aqua ammonia or vapo(u)r blasting, and the sealing of guide pin bushing interface must not leak flue dust, and " blocking up " digests in system.
The former amount of investment is big, mechanism is complicated, fan energy consumption is high, and burns still and can cause secondary pollution, and just the form of polluting changes, also loss in vain some useful resources.External as Japan, the Soviet Union etc. mostly adopt this method, Baosteel with introduction day present technique is an example, terrestrial station's part has promptly been invested millions of units, disregard the routine maintenance loss, the power consumption of two total volume 1410kw blower fans and water consumption 50t/h handle the coal-charging smoke of two coke ovens, and present domestic coke-oven plant all is difficult to bear.
Latter's less investment domesticly mostly adopts this method, but the sealing of guide pin bushing interface is crucial, and Germany adopts the hydraulic machinery sealing, but mechanism's complexity, technical difficulty is big, and domestic still do not have.Domestic newly-built stove generally adopts the double collecting main road to reduce draw resistance, but most of single effuser coke oven just aspirates this measure by high pressure aqua ammonia, it is very little to produce effects, raising ammonia pressures, increase suction also are difficult to produce effects, cause coal gas, quality of coke tar to descend on the contrary, increased recovery system operation burden, the ZL93216277.0 patent is settled in the oven coke side and is led the cigarette dolly, but, fail to produce a desired effect also because of the guide pin bushing place blow-by of coalingging.In order to solve guide pin bushing sealing, once adopted German flexible pipe sealing, but because the not anti-high temperature of flexible pipe, very fast being burnt out and fizzling out.
The utility model is to design a kind of good sealing effect, the long-lived novel guide pin bushing coal tightness system of coalingging at above-mentioned the deficiencies in the prior art.
The utility model is owing to adopt the principle of water seal to make the guide pin bushing sealing, inflammable gas and atmospheric isolation in the cover with regard to not can fire burns, also not having flue dust leaks, moreover the quick a large amount of adding coking chamber of the cold coal that contains moisture, make the decline of coking chamber furnace temperature, coal charge be difficult to gasification, gas volume minimizing, spray with high pressure aqua ammonia and attract just can produce better negative pressure effect at the effuser place like this.
This device movable guide pin bushing and fixedly between the guide tube with water sealing structure sealing (seeing accompanying drawing 1).The utility model is made up of the fixedly guide tube 2 of mutual isolated band spacer 4 and movable guide pin bushing 7 two portions of band water sealed tank 6.For avoiding the sticking wall of corrosion and coal charge to adopt 6 mm thick stainless steel plates to roll welding.
Replace the fixedly suitable for reading and coal charger coal groove elephant trunk centering welding of guide tube of the movable guide pin bushing of original coal charger with this device, the movable guide pin bushing of band water sealed tank hangs on the suspension rod of original hoisting appliance by ball-and-socket hinge device.When coking chamber is coaling, car is reached the position, open the stoke hole bell, start the hoisting appliance guide pin bushing of will coalingging and fall in the stoke hole seat, wait to coaling to finish and mention guide pin bushing, bell on the cleaning bonnet, the coal charger that drives away is finished the operation of coalingging to this.
Adopt stiff dough sealed structure between the stoke hole seat 9 of guide pin bushing interface 8 and coke oven furnace roof, slip into centering, the interior cone angle of cover by 50 ° of designs, make it to be difficult for long-pending coal as long as guide pin bushing falls into the interior promptly reliable deadweight of the stoke hole seat conical surface with tapering.
Water sealed tank top is established a flowing full groove 5 that enlarges and is made guide pin bushing be higher than the flowing full groove, the i.e. fluctuation in stage that the variation of cover internal pressure causes in water seal is adjusted automatically by change of level less in the flowing full groove, to adapt to the positive negative pressure variation (by malleation 400mm water column, the design of negative pressure 100mm water column) that may occur in the coal process coking chamber.And float ball at surface coverage one deck of water, to increase the stability of the water surface, make it in the scope of design can because of coal charger walking vibration, when coalingging lifting guide pin bushing rock with working pressure change cause liquid fluctuating cause water to overflow and outside spatter.
Guide pin bushing is driven by hoisting appliance, and lifting travel 300mm covers bell and cleaning so that take off.
Adopt spherical hinging mechanism between guide pin bushing and the hoisting appliance, (Fig. 2) arm of hoisting appliance flexibly connects (Fig. 1 " A " portion) with guide pin bushing water sealed tank 6 and makes it can arbitrarily swing by external force at lifting process by bearing pin 14, suspension ring 16, ball bearing 11, the suspension rod 18 of ball-and-socket hinge device, to adapt to the deviation of fire door position, make guide pin bushing can import the stoke hole seat in the larger context, guarantee that two sealing cones fit tightly under gravity and seal.
For fear of with reduce dust and fall into tank, be provided with calotte 3 on the top of guide pin bushing, in establish dust-blocking cover of making of ceramic fiber 13 and the wash water valve that is provided with cleaning usefulness at bottom of gullet.
Only need during use water is added to the water seal height that waterline (junction surface of tank and flowing full groove) forms design.
This device has following advantage:
The flue dust that produces when 1, coalingging can not leak, and has reduced pollution, and resource is utilized.
