Abstract

The invention provides a micro water gas generator. Water and coal are compounded to generate combustible gas. The micro water gas generator consists of a steam generator, a heat conduction ceramic heating and reacting plate, a gas-liquid separation cover, a gas-liquid separation cavity, a water gas outlet, a convolute combustor and an automatic coal feeder, wherein the steam generator supplies steam to the coal on the ceramic heating and reacting plate; gas produced from reaction enters the gas-liquid separation cavity through the gas-liquid separation cover for separation; part of combustible gas enters the convolute combustor for combusting and supplying the heat required by the steam generator; the coal is supplied continuously by the automatic coal feeder; and the produced combustible gas is led out from the water gas outlet. The advantage is that the combustible gas produced by the water gas generator is high in purity and good in integral economic benefit.

Description

Blue-gas generator

Technical field

The present invention relates to a kind of producer gas generator, especially blue-gas generator.

Background technology

Coal gasification in present producer gas generator is divided into dry distillation and two processes of gasification.Enter stove coal cinder (bituminous coal) at dry distillation section slow decreasing, the heating gas that rises with gasification section carries out directly and countercurrent exchange indirectly, through super-dry, preheating, dry distillation three phases, make the things such as fugitive constituent in coal cinder, moisture raise and progressively separate out with temperature, produce dry distillation coal gas and form semicoke, semicoke enters gasification section and is gasified totally.The heating gas that gasification section produces, 60-70% wherein goes out lower part outlet and draws, and is called lower coal gas, and 30-40% mixes with dry distillation coal gas through the dry distillation section in addition, and the outlet of top, mountain is drawn, and is called coal gas.

Several stages below the physical chemistry main transformerization that coal occurs in the dry distillation section mainly comprises:

1, drying stage (150 ℃): surface water, planar water evaporation in coal.

2, pre-heating stage (150-300 ℃): in the time of 150 ℃-300 ℃, emit crystal water when few, carbonic acid gas and hydrocarbon polymer in coal.In the time of 200 ℃-300 ℃, in coal, compound begins to decompose, and carbonic acid gas increases, and emits a small amount of tar.

3, the dry distillation stage (300-600 ℃): in the time of 300-400 ℃, coal begins to soften, and decomposites inflammable gas, the tar gas such as unsaturated hydrocarbons, methane, hydrogen; In the time of 400-450 ℃, decomposite in a large number tar gas; 500-600 ℃ does not substantially produce tar and forms semicoke.

Redox reaction when coal with gasification host (air, water vapor), complexity occurs in the gas section generates inflammable gas and the carbonic acid gas such as carbon monoxide, hydrogen, and the principal reaction process can represent with following a few prescription formulas:

1、C+O2＝CO2+Q

2,2H2O (vapour)=2H2+Q2-Q

3、CO2+C＝2CO-Q

4, H2O (vapour)+C=CO+H2-Q

5,2H2O (vapour)+C=CO2+2H2-Q

And present producer gas generator is mainly to maximize, and is not suitable for medium-sized and small enterprises and uses.

Summary of the invention

The invention provides a kind of miniature blue-gas generator.

a kind of blue-gas generator, become inflammable gas by water with the coalification symphysis, it is characterized in that by steam generator, thermal conductive ceramic reacting by heating dish, the gas-liquid separation cover, gas-liquid separation chamber, the water-gas export mouth, the convolution burner, automatically the device of delivering coal forms, steam generator supply water vapour is to the coal on the ceramic heat reaction tray, the gas that reaction generates is through the gas-liquid separation cover, entering gas-liquid separation chamber separates, the part inflammable gas enters the convolution burner and burns, the required heat of supply steam generator, coal continues supply by the device of automatically delivering coal, the inflammable gas water-gas export mouth that generates is derived.

Produce an effect has like this, and the inflammable gas purity that the Miniature water producer gas generator generates is higher, and whole is good in economic efficiency.

Description of drawings

Accompanying drawing is structural representation of the present invention.

Wherein: 1. the device of automatically delivering coal; 2. water-gas export mouth; 3. gas-liquid separation cover; 4. thermal conductive ceramic reacting by heating dish; 5. steam generator; 6. gas-liquid refrigerated separation chamber; 7. convolution burner.

Embodiment

The present invention will be further described below in conjunction with accompanying drawing: steam generator 5 supply water vapour are to the coal on ceramic heat reaction tray 4, the gas that reaction generates is through gas-liquid separation cover 3, entering gas-liquid separation chamber 6 separates, the part inflammable gas enters convolution burner 7 and burns, the required heat of supply steam generator, coal continues supply by the device 1 of automatically delivering coal, and derives in the inflammable gas water-gas export mouth 2 that generates.

In preferred version, water can first participate in the cooling of gas-liquid refrigerated separation chamber, realizes simultaneously heating up, and then imports steam generator.

In preferred version, it is anti-oxidant that the inner employing of burner hearth is coated with pottery, and with the calcium carbonate that adds 3～5% in coal cinder, can eliminate most of sulphur emissions.

Adopt producer gas generator of the present invention, can supply the artificial coal gas of 5-5000m3/ day, be applied to the places such as middle-size and small-size dining room, boiler, improve energy utilization rate, realize economizing on coal 30～50%, and decrease pollutes.
