The utility model relates to a kind of positive pressure operation of air blast up and down formula producer gas generator of producing low middle calorific value of gas with coal as raw material.
Existing producer gas generator kind is a lot, and mostly that wherein generally adopts is malleation bottom blowing moulded coal gas producer, no matter is water-gas generators or low calorific value coal gas producer, and its requirement to raw materials used coal is all higher.When using bituminous coal as raw material, the back must have except that equipment such as tar, sewage disposal and desulfurization, thereby construction investment increases, floor space is big, reflecting gas producer occurred at these shortcomings, but this type of furnace adopts downdraft, gas exit adopts vacuum take-off, cooling before the stove final vacuum pump, purification system equipment and pipe negative pressure operation, air easily bleeds.All above-mentioned type of furnaces all have only a zone of oxidation, and the unavoidable meeting of raw material burning of coal incomplete phenomenon occurs and makes raw material fail to be fully utilized, carbon content height in lime-ash.
At the problems referred to above, positive reflecting gas producer and double bed coal combustion gas producer have appearred at present, but the same method that all adopts the vacuum take-off gas exit of these producers with reflecting gas producer, all negative-pressure operations in the stove, from at the bottom of the gas furnace to the coal gas dust removal between the water-ring vacuum pump, cooling system all are negative-pressure operation states, the not only very easy air that bleeds causes blast, and power consumption is also big, the coal gas dust removal difficulty.
The purpose of this utility model is drawn the advantage of positive pressure air top blast producer gas generator just at the problem of above-mentioned existence, proposes a kind of air blast malleation producer gas generator up and down.Keep positive pressure operation in this type of furnace stove, gas exit needn't vacuum take-off, operational safety, and tar decomposes fully, pollutes for a short time, and thermosteresis is few, and ash content carbon is low.
Order of the present utility model can reach by following measure, blasts air by top and furnace bottom simultaneously in a body of heater, respectively forms the producer gas generator of zone of oxidation up and down.It is by forming as the epimere body of heater of malleation top blast producer gas generator with as the hypomere body of heater of malleation bottom blowing coal gas producer, and gas exit is located at the middle part of producer, and the exit is provided with collet.Two ends are equipped with the inlet that blasts vaporized chemical up and down.Body of heater has upper and lower two water jackets.The dreg removing system that the body of heater bottom is made up of travelling grate, break circle, transmission rig and water seal ash-pan.
The utility model compared with prior art has following advantage:
Owing to adopt two sections relative gasifications of epimere gas-solid following current contact and hypomere gas-solid counter current contact in the stove, the gasification reaction area is twice than increasing during single gasification reaction area in the stove like this, and gas production rate doubles, gasification efficiency improves, material combusting is complete, and the tar complete decomposition has reduced pollution.Positive and negative fire gas producer or double bed zone of combustion producer gas generator relatively have the technological merit identical than the downdraft reflecting gas producer with air top blast producer gas generator.Characteristics such as cleavable tar, simplification gas production technology have promptly been kept.We can say the advantage that positive and negative fire gas producer and double bed coal combustion gas producer have, the utility model has all obtained reservation, also has following the above two advantages of not having simultaneously:
1, gas production is safe and reliable, because system's malleation air blast makes total system be in barotropic state operation, avoided because suction coal gas makes gas exit all be in negative pressure state and the air that easily bleeds mixes the danger of blasting with coal gas to vacuum pump coal gas dust removal the last period cooling apparatus and pipeline.
2, to aspirate used power consumption than vacuum much smaller for the electric power of the required gas blower consumption of blast head, saved power consumption like this, saved facility investment.
3, positive pressure operation is convenient to coal gas cyclone dust removal, and equipment can not damaged and shut-down maintenance because of a large amount of carry-overs easily cause, and guarantees that the equipment long-play can't go wrong.
4, the sensible heat of taking out of in the coal gas is recycled again, the steam decomposition rate the when steam in the boiler after overheated can improve reaction in furnace greatly.
5, form double-deck gasification, vapourizing furnace throughput improves, and carbon content of cinder is few, save energy.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is a structure iron of the present utility model.
Fig. 2 is a process flow sheet of the present utility model.
As shown in Figure 1, coal supply apparatus (1) is the double belljar sealed structure, is made up of upper and lower two coal bins.This device can satisfy automatically and manual dual mode coal.Epimere furnace body (3) partly is made up of water jacket (4) upper end gasification agent inlet (10) and gas exit collet (11) and refractory materials etc.Hypomere furnace body (12) is made up of water jacket (6) break circle parts such as (7).Hypomere body of heater vaporized chemical is blasted by the hypomere body of heater gasification agent inlet (15) that links to each other with fire grate (13).Gas exit (5) is at the body of heater middle part, and whole body of heater external application metal shell supports that body of heater and auxiliary facility weight support by supporting (16).The ash disposal system of vapourizing furnace is made up of water seal ash-pan (14), fire grate (13), grey cutter, water seal.Fire grate (13) has the effect of bearing material, even distributing wind, break, loosening furnace charge concurrently.The transmission of ash disposal system is made up of motor, reduction box (9) and worm and gear (8).
Vapourizing furnace is when operation, and coal charge is added in the stove by coal supply apparatus (1), evenly is distributed in the stove through distributor (2).The required vaporized chemical of epimere stove is blown into to contact with the coal charge following current by epimere stove blast entrance (10) and reacts, and forms destructive distillation band, epimere burning cracking band, reductive cleavage band in stove.The destructive distillation product enters zone of combustion and zone of reduction with vaporized chemical in this section coal, and its coal-tar middle oil contour molecular weight product is heated at this and takes place further to decompose, and forms effective constituent such as methane and flows out with coal gas.Coal charge after disposable gasification is reduced to the body of heater hypomere, and the solid of this moment has been coke, when the air inversion that blasts with the body of heater bottom meets, gasification reaction for the second time takes place, and forms hypomere zone of combustion and zone of reduction.Owing to positive pressure operation, the coal gas of air blast formation flows out by the gas exit (5) at middle part up and down, enters tornado dust collector and removes the particle of carrying secretly in the coal gas in the stove.Afterwards, heating gas enters interchanger and carries out heat exchange, utilizes the sensible heat superheated vapour in the heating gas, to improve the efficiency of utilization of whole gasified boiler system.The force feed gas holder is for user's use after directly spray cooling, dedusting and gas-liquid separation purify again for coal gas after the heat exchange, and Fig. 2 is seen in the technical process of whole system gas and purification.
