Abstract
The utility model provides an external heating water gas generator which adopts an external heating gasification structure. A radiation heater is arranged in a hearth, and a combustion chamber of the radiation heater is isolated from a gasification chamber of the water gas generator. Meanwhile, a burner is arranged on the periphery of the radiation heater. The utility model overcomes the defects of the existing water gas generators, continuously produces complete water gas, enhances efficiency and the quality of the gas and reduces the labor intensity of operation. The utility model is suitable for requirements for producing the gas in every field which needs the gas in national economy.
Description
The utility model relates to a kind of producer gas generator, and a kind of external-heat blue-gas generator belongs to the gasification of coal field.
The existing coal method of being gasified totally is that coal in stove internal combustion some amount is to provide gasification reaction required heat.Because incendiary needs, and air is provided in stove, this just makes a large amount of nitrogen infiltrate among the coal gas, and caloric power of gas is reduced.When replacing air with oxo, though can improve caloric power of gas, need a large amount of oxygen, cost improves a lot; When adopting existing water-gas production method to come batch production coal gas, calorific value water-gas in also can producing can not carry out continuously but produce, thereby transformation efficiency is low, and manipulation strength is big.
Task of the present utility model is exactly in order to overcome the above-mentioned defective of existing gasification process, design a kind of both can continuous production in calorific value water-gas, do not need oxygenation again, efficient height simultaneously, the external-heat blue-gas generator that manipulation strength is low.
Technical solution of the present utility model is as follows:
Producer gas generator adopts the external-heat gasification structure, and its basic pattern is similar to common producer gas generator.One width of cloth is set in burner hearth penetrates well heater, the burner combustion water-gas of well heater is emitted heat, and the heating raw coal reaches behind the gasification temperature and water vapor generation water-gas reaction, and coal is gasified totally is water-gas.The water-gas that produces can lean on the top water vapor pressure to discharge from the bottom, and also the vacuum available pump is extracted out from the bottom.The water-gas of coming out of the stove is after purifying treatment, and some is sent to gas-holder or field of employment for using, and another is partly sent into the width of cloth and penetrates the well heater burning to keep temperature of reaction.The width of cloth is penetrated the high-temperature flue gas of discharging in the well heater and can be made vaporized chemical with the reaction of production process steam air feed through a heat exchanger heat exchange from the high-temperature water gas that furnace bottom is discharged and use.Because this furnace gas institute heat requirement is penetrated well heater by the width of cloth and provided, the width of cloth is penetrated the burning chamber of well heater and the gasification chamber implementation of producer gas generator completely cuts off, thereby has avoided a large amount of nitrogen to infiltrate among the coal gas, has guaranteed gas quality; Even heating continuously carries out gasification work continuously again.High-temperature flue gas of discharging and water-gas are fully used heat after the interchanger heat exchange, have improved the efficient of producer gas generator.
To the further detailed description of the utility model, figure one is the structural representation of this stove below in conjunction with accompanying drawing.
Body of heater 4 is main parts of producer gas generator, has the width of cloth to penetrate well heater 5 in it and is attached thereto, and peripheral disposition has burner 6, smoke outlet 3 and process steam-in 2, and its top is connected with furnace roof 1, and furnace roof 1 is provided with manhole cover 13.The bottom of body of heater 4 links to each other with stove seat 7 on being supported on pillar 9, is provided with water seal circle 11 in stove seat 7, and gas exit 8 and thin slag device 12 are connected with the auger 10 of slagging tap in the bottom of stove seat 7.
Open the manhole cover 13 at furnace roof 1 top, can add feed coal from furnace roof 1 top, the cone distributed uniform that the feed coal that adds is penetrated well heater 5 tops by the width of cloth falls into the width of cloth and penetrates between the inwall of well heater 5 and body of heater 4, is penetrated the well heater even heating by the width of cloth, and the temperature of feed coal is progressively rising from top to bottom.When temperature progressively raises, feed coal is at first by destructive distillation coke or semicoke, and separate out coal tar and various inflammable gas simultaneously, further rising along with temperature, coke or semicoke promptly with the water vapor generation water-gas reaction that adds from steam entry 2, fully be converted into water-gas, the inflammable gas that the coal tar of separating out during destructive distillation also takes place to separate out when scission reaction generates inflammable gas and water-gas and destructive distillation is mixed and discharges or extract out from coal gas relief outlet 8.The water-gas of discharging is sent to the field of employment after treatment, and wherein some is admitted to burner 6 and penetrates well heater 5 internal combustion at the width of cloth, and incendiary waste gas is discharged from exhanst gas outlet 3.Lime-ash after gasification is dredged down by thin slag device 12, falls into the bottom of stove seat 7, is discharged by the auger 10 of slagging tap again.
This external-heat blue-gas generator institute producing coal gas can be used for industry and uses combustion gas with life, also can be used as industrial chemicals.
