Description
The utility model relates to a kind of gas generator, especially a kind of suction type gas generator.
The gas generator that present each producer uses has the type of furnace of counter-burning type, the type of furnace that the malleation normal burning is arranged, the gas generator body of heater top of this type of furnace is not sealed, and body of heater itself is not provided with the clean room, generally send into air from bottom of furnace body by air blast, send into from bottom of furnace body by the water vapour that the boiler of other setting produces, the gas mixture that produces is gone out by the body of heater top, pass through deduster, aeration tower, digester, vertical tube, decoking device, spark arrester, explosion-protection equipment successively, the entire equipment floor space is big, and system is numerous and diverse; Dedusting all outside body of heater, is polluted big like this; Because of taking the air blast air-supply, noise is big again; Because it is the imflammable gas that the gas mixture that produces contains is many, at the direct draught of body of heater, very easily produces pinking, dangerous big; Equipment is many, thereby investment is big.
The purpose of this utility model provides a kind of simple to operate, safe and reliable, and no coal gas leaks, and no tempering phenomenon of detonation guarantees that self-produced steam is self-sufficient, realizes the suction type gas generator of coal gas furnace purge.
The technical solution of the utility model is as follows: a kind of suction type gas generator, comprise the vertically arranged body of heater that has top cover, coal filling hole is arranged on the top cover, be provided with grey chamber, fire grate, burner hearth from the bottom up successively along body of heater, burner hearth has water jacket outward, in the middle and upper part of body of heater the one coal gas collecting chamber around body of heater is arranged, body of heater has a vavuum pump and coal gas collecting chamber to join outward; Between water jacket and the burner hearth heat-insulation layer is arranged, below the coal filling hole at body of heater top, the clean room is arranged, be connected with air intake duct between clean room and the coal gas collecting chamber; Be connected to the vapor collection pipe under the clean room on water jacket, the outer steam pipe of body of heater parallels with the longitudinal axis of body of heater, and its top communicates with the vapor collection pipe, and the bottom communicates with the blast pipe that is positioned at grey chamber outer wall; The top of body of heater is sealed.
Described clean room communicates with roof of the furnace, is the band of column around burner hearth, and the shape of described coal gas collecting chamber is similar to the shape of clean room.
Effect of the present utility model is as follows:
1) safe and reliable: as because of adopting vavuum pump burner hearth to be pumped into negative pressure, to be difficult for producing the tempering pinking.
2) protection environment: self has the clean room body of heater, not directly to the airborne release flue dust, reduces and pollutes.
3) floor space is little, small investment: because of do not have air blast, aeration tower,, digester, spark arrester, explosion-protection equipment, equipment is few like this, cost of investment is also little.
4) energy savings: adopt negative-pressure firing, coal combustion is abundant, and the coal consumption in the unit interval is little, because of with the self-produced steam of gas generator, need not to want steam generating equipment again again, thereby energy savings.
5) product miniaturization, seriation, of many uses, be fit to all kinds of medicinal materials, matrimony vine, silk cocoon oven dry and hotel, dining room, industrial civilian.
6) thermal efficiency height is easy to operate.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is the structural representation of the utility model body of heater;
Fig. 2 is the utility model process flow diagram:
Embodiment: a kind of suction type gas generator, comprise vertically arranged 1 the body of heater 12 that has top cover, coal filling hole 23 is arranged on the top cover 1, be provided with grey chamber 24, fire grate 8, burner hearth 22 from the bottom up successively along body of heater 12, water jacket 7 is arranged outside the burner hearth 22, the one coal gas collecting chamber 5 around body of heater 12 is arranged in the middle and upper part of body of heater 12, have a vavuum pump 14 to join outside the body of heater 12 with coal gas collecting chamber 5; Between water jacket 7 and the burner hearth 22 heat-insulation layer 6 is arranged, below the top of body of heater 12 coal filling hole 23, clean room 2 is arranged, be connected with air intake duct 4 between clean room 2 and the coal gas collecting chamber 5; Be connected to vapor collection pipe 3 on the water jacket 7 under the clean room 2, have a steam pipe 21 parallel with the longitudinal axis of body of heater 12 outside the body of heater 12, its top communicates with vapor collection pipe 3, and the bottom communicates with the blast pipe 9 that is positioned at grey chamber 24 outer walls; The top of body of heater 12 is sealed.Described clean room 2 communicates with burner hearth 22 tops, is the band of column around burner hearth 22, and the shape of described coal gas collecting chamber 5 is similar to the shape of clean room 2; Described air intake duct 4 is evenly equipped with 4 along the outer wall of body of heater 12; The mixture of active carbon and particle is housed in the described clean room 2; Described body of heater 12 is circular.
When opening stove, coal is sent in the burner hearth 22 from coal filling hole 23, coal drops on the fire grate 8, open vavuum pump 14, under the suction of vavuum pump 14, air is inhaled in the burner hearth 22 from blast pipe 9, coal begins to be heated drying, when it produces carbon dioxide along with burning of coal, emit a large amount of heat with heating of the water in the water jacket 7 and generation steam, open vapor collection pipe 3 water vapour is imported in the ajutage 9 this moment, allow water vapour send in the burner hearth 22, enter reducing zone through the carbon dioxide that produces behind the oxidation drying and be reduced into carbon monoxide, run into fuel gas and mixture of steam and imperfect combustion coal grains such as just generating hydrogen behind the water vapour on burner hearth 22 tops, sulphur, impurity such as carbon dioxide, these impurity enter in the clean room 2 along burner hearth 22 tops together with coal gas, owing in the clean room 2 active carbon and sand grains are housed, has catharsis, impurity just is attracted in the clean room 2, the clean coal gas that has a part of water vapour reenters in the coal gas collecting chamber 5 certainly from air intake duct 4 internal causes of 2 bottoms, clean room, be sucked out the body of heater 12 outer heat exchangers 13 that enter then, once lower the temperature, cavity through straight empty pump 14 enters moisture trap 15, go out the coal gas of moisture trap 15, just can be used for various medicinal materials, matrimony vine, silk cocoon oven dry and hotel, the dining room, industry is civilian.Water in the water jacket 7 is squeezed in the water jacket through pump 17 by lower water box 16, and the water of sedimentation directly enters in the lower water box 16 in heat exchanger 13, vavuum pump 14, the moisture trap 15, does not waste the water source like this, utilizes circulation to realize the supply and the collection of water.Muff 6 can be built by laying bricks or stones with refractory brick, play insulation effect, prevent scattering and disappearing of burner hearth 22 interior heats, guarantee the required temperature of oxidation, drying, reduction of coal, coal combustion forms big lime-ash and can remove from clean-out door 11, thin ash can be from cleaning door 10 cleanings, and entire equipment can manually-operated, also can realize mechanized operation.
