Description

Gas producer

Technical field

The utility model relates to utilize biomass to gasify, produce the device of combustion gas for raw material, and particularly a kind of is raw material with the coal, produces the gas producer with environmental protection, energy conservation characteristic of combustion gas.

Background technology

At present, there are following all weak points in used gas producer in the daily life: one, the primary structure of gas producer all is the downside that the outlet of combustion gas is arranged on body of heater, and the mixture of air and water vapour is blasted by the top of gas blower from body of heater, cause a large amount of CO2 to produce, greatly reduce the transformation efficiency of the energy; Its two, the intravital slag of stove in the process of discharging, produces many dust, severe contamination around environment; Its three, the combustion gas that produces in body of heater is not carried out the gas washing of combustion gas and is handled after the discharge, just directly derive use, thereby cause the purity of combustion gas not high; Its four, level of automation is low, the gas producer that has also adopts manual cloth, manual deslagging, inefficiency, wastes time and energy.

Summary of the invention

The purpose of this utility model provides a kind of improved gas producer, can greatly improve the transformation efficiency of the energy, eliminates dust to reduce environmental pollution; The combustion gas that the utility model can be produced extreme high purity simultaneously; The utility model also adopts the device of automatic sludge discharge, so have the level of automation height, characteristics easy and simple to handle, time saving and energy saving.

The technical scheme that the utility model adopted is as follows: the utility model is formed by advancing device for coal, body of heater, interchanger, gas bag, gas washing tube, transmission mechanism automatically.Wherein, automatically the coal bin that advances device for coal links to each other with the vertical opening for feed of body of heater, leaks in order to prevent coal gas, and coal bin is provided with valve and following valve, when coal in stove, do not allow two valve to open simultaneously, can open another valve after can only closing a valve; Coal penetrating port is in order to handle the work of stove.The upper body of stove is made up of outermost steel shell, thermal insulation layer, air-casing, refractory brick, and the automatic sludge discharge stone or metal plate for standing a stove on as a precaution against fire is housed on the lower body of stove, and it is discharged to dirt-excluding bucket by the electrical motor gearshift transmission with lime-ash.The position of the central part on the automatic sludge discharge stone or metal plate for standing a stove on as a precaution against fire is welded with three layers of stair-stepping ventilation terminal, in the body of heater upper side combustion gas relief outlet is arranged, and this outlet is connected with exchanging air, and in order to obtain highly purified combustion gas, combustion gas imports the gas washing tube by exchanging air.There is water in the dirt-excluding bucket, dust from flying when adopting water seal to prevent the falling stop slag.

The beneficial effects of the utility model;

1, obviously improved the transformation efficiency of the energy, transformation efficiency can reach about 70%, compares with traditional gas producer and has improved 30%.

Because the utility model is that air and water vapour are blasted by the ventilation terminal of gas blower from the bottom of body of heater, the gas that blasts at first passes through ash bed, and obtain preheating at this, produce CO and CO2 with the coal generation oxidizing reaction that reaches point of ignition above the lime-ash then, the CO2 gas that forms upwards flows and reduction reaction takes place in the coal seam of upper strata extreme temperatures, thereby with the CO2 gas reforming is CO gas, so just greatly improved rate of energy, the intravital coal seam of stove this moment from bottom to top forms: ash bed, zone of oxidation, reducing zone, the destructive distillation layer, drying layer, the combustion gas of Sheng Chenging at last accumulates in more than the bed of material, discharges by the lateral gas outlet of upper of furnace body.

2, eliminate dust, reach the purpose of environmental protection:

Owing to dirt-excluding bucket is housed in the bottom of body of heater, water is housed in the dirt-excluding bucket, dust from flying during with anti-falling stop slag of the mode of water seal and deslagging reaches the effect that reduces atmospheric pollution, protection surrounding enviroment.

3, mechanization degree improves a lot, and is time saving and energy saving:

Because the automatic sludge discharge stone or metal plate for standing a stove on as a precaution against fire is housed in body of heater, under the drive of motor, can speed change rotate, make the slag on the stone or metal plate for standing a stove on as a precaution against fire, move along edge radially to stone or metal plate for standing a stove on as a precaution against fire, slag just falls into dirt-excluding bucket from the slit between intravital inwall of stove and the stone or metal plate for standing a stove on as a precaution against fire.
