Description

Gas generator

The utility model relates to the producer gas generator technical field.

As everybody knows, Chang Yong producer gas generator aerogenesis mode roughly has two kinds: a kind of is water directly to be splashed into the stove hall coal gas takes place; Another kind is on the furnace hearth wall limit vapour generator to be set, and by heat aqueous vapor generation steam is entered the stove hall coal gas takes place, and there are many problems in this dual mode, as: stove hall local temperature obviously reduces, and the coal seam non-uniform temperature influences aerogenesis, the ash carbon content increases, and dust is many.The easy scaling of vaporizer, the vapor generation deleterious, the easy dross in furnace wall starts with the time of giving vent to anger long, gas shakiness, firepower are difficult to control, make source of the gas with hard coal, and stove is aerogenesis not, or have only faint coal gas, and can't use the shower nozzle burning, the thermal insulation layer degradation, heat waste is big.

The purpose of this utility model is to provide a kind of thermo-efficiency to significantly improve, and burning is complete, and coal gas produces fully, stablizes.Can use the shower nozzle burning, firepower can arbitrarily be controlled, and can use hard coal to make the producer gas generator of source of the gas.

The technical solution of the utility model is achieved in that it is made up of several parts such as body of heater, steam-generating installation, shower nozzle, slag unloading device and bearings.Body of heater comprises refractory materials thermal insulation layer, the furnace lining in furnace shell, the shell, also comprises a full encirclement wind chuck that is arranged between thermal insulation layer and the furnace lining, is shaped on spiral aviation baffle in the wind chuck; Steam-generating installation is made of air inlet device and water feed apparatus, air inlet device comprises the outer gas blower of furnace shell, passes the blast pipe that furnace shell communicates with wind chuck top, also comprise the wind chuck, water feed apparatus comprises water tank, the valve that furnace shell is outer, and pass the water inlet pipe that furnace shell communicates with wind chuck bottom, the inwall of wind chuck bottom has some openings, and the chamber that its bottom surface to this section of opening highly forms can be filled with water, and promptly constitutes evaporation tank; The shower nozzle part links to each other by burner and with burner and the dust-proof plate of shelves at the fire door place constitutes; Slag bucket that slag dumping partly seals mutually by the fire grate of furnace lining bottom, with the body of heater bottom surface and the slag bucket carriage of controlling the slag bucket lifting constitute; There are several bearings to be used for supporting body of heater.

Its principle of work is summarized as follows: freezing air is after the gas blower supercharging, enter spiral preheating from top to bottom in the full encirclement wind chuck, form warm air, the water (being splashed into by water inlet pipe) in the evaporation tank of warm air bottom the wind chuck contacts, with water vapor, and mix with it, give vent to anger from the opening of wind chuck bottom interior wall, enter Lu Tang, gasification, coal gas rises and walks around dust-proof plate to shower nozzle, burns with air mixed.

Surround the wind chuck entirely by last employing, make the freezing air spiral can fully absorb everywhere the heat that dispels the heat, particularly absorbed the coal gas that will export widely, and these transfer of heat are used for gasified water in the evaporation tank of wind chuck bottom, steam enters from stove hall bottom.So heat waste is minimum, thermo-efficiency significantly improves, and stove hall internal combustion is complete, gas production rate is big, and each coal seam temperature is even; The dust rising that produces runs into dust-proof plate and can fall after rise in Lu Tang automatically, so the coal gas of ejection is very clean, environment protection is good; Because the air endothermic effect is good, the heat that distributes on the furnace lining wall is absorbed to greatest extent, furnace lining can not be in the common condition of high temperature, so the furnace lining inwall is difficult for dross, it is so high not resemble conventional oven to the requirement of furnace lining, the thickness that is furnace lining can approach, and the requirement of material also can be hanged down, and this has reduced cost beyond doubt; Because vapor generation is to produce in the evaporation tank of wind chuck bottom, evaporation tank has been avoided furnace lining, is again directly to use the warm air vaporize water, so evaporation tank is less scaling; Even just in case fouling, can not influence aerogenesis yet, because water inlet can splash into continuously always, water droplet is many, and evaporation tank expire, and water overflows and drops into slag bucket from vapour outlet naturally, outwell during slag dumping, do not influence other parts at all, also have, the firepower of this stove can regulated at will, by regulating the matching relationship of air output and flooding quantity, change quantity of steam, reach change coal gas generating capacity, thereby reach the size of control firepower, quantity of steam is big, the coal gas generating capacity is increase, otherwise then reduces, and firepower is also corresponding big or little.

Be illustrated below in conjunction with drawings and Examples:

Fig. 1 is the utility model structural representation;

Fig. 2 is the complete jacket structured synoptic diagram of wind that surrounds.

As shown in Figure 1 and Figure 2, the utility model is by oven body part (comprise furnace shell 2, refractory materials thermal insulation layer 3, surround wind chuck 4, furnace lining 6 entirely), vapor generation part (comprise gas blower 8, blast pipe 7, wind chuck 4, water tank 10, valve 11, observe meter 12, water inlet pipe 13, water-in C, evaporation tank D, air outlet E), shower nozzle part (comprising burner 1, dust-proof plate 9), several sections such as slag dumping part (comprising drop grate 18, drop grate operating stick 14, slag bucket 17, slag bucket carriage 15) and bearing 16 constitute.Furnace shell, furnace lining, wind chuck all are the garden tubular, the wind chuck is double-deck, and its inside is shaped on spiral aviation baffle from top to bottom, and its shape is up big and down small, the top of wind chuck communicates with blast pipe, the bottom of the wind chuck furnace lining that reclines communicates with water inlet pipe, and water splashes into the bottom, natural formation garden, bottom cyclic evaporation tank, its vapour outlet E opened on the inwall garden week of distance bottom surface corresponding height, and quantity is 3, and quantity can be several; Slag bucket and body of heater bottom surface are sealed state, and coal feeding hole is (figure part omitted picture) on sidewall of the furnace body.During work; the water that the freezing air spiral is preheated in the warm air contact evaporation tank forms steam, because slag bucket and furnace bottom are sealed state, so; steam can not leak; all enter stove hall B, make gasification, coal gas passes the A chamber, top (major diameter part) that each coal seam enters the wind chuck; run into dust-proof plate 9 at the fire door place; dust falls stove hall B after rise, and clean coal gas is walked around dust-proof plate and entered burner 1 and burn with air mixed, and the A chamber can claim falling dust room.During slag dumping, need only shake control stick 14, drop grate 18 is just opened, and slag drops down onto slag bucket 17, and the slag burden need only be handled slag bucket carriage 15 and just can fall slag bucket for a long time in slag bucket, pours out and deposits slag.The wind chuck can fully absorb furnace lining, thermal insulation layer, the heat radiation of furnace shell, particularly can absorb the heat that coal gas was attaching in the falling dust room, and the heat of these all absorptions is delivered to the bottom steam takes place sends into the stove hall, so thermo-efficiency significantly improves, evaporation tank is again to be positioned at wind chuck bottom, avoided furnace lining, so less scaling, if fouling can not influence aerogenesis yet, because water inlet can be successive, water is many, and nature overflows from air outlet E flows to slag bucket, outwell with slag, thus be not afraid of, thus make steam generating amount keep stable, the size of steam generating amount can be regulated, need only regulate air outputs and drip by observation by gas blower 8 and observe meter 12 and control flooding quantity, the relationship of the two is matched, steam generating amount be just changeable, the coal gas generating capacity is also just changeable, and firepower can arbitrarily be controlled.Because the air heat absorption capacity is very strong in the wind chuck, temperature of furnace lining has reduced relatively, and the furnace lining wall is difficult for dross, then the performance requriements to furnace lining and refractory materials thermal insulation layer can correspondingly reduce, can do to such an extent that to resemble conventional oven so thick, or select the high-performance refractory material for use, so just reduce cost.
