Abstract

The utility model relates to a multipurpose coal gas generator, which solves the dust pollution problem to the environment caused by the direct coal combustion of the common coal stove. The utility model is characterized in that the wet dust extraction is realized by adding a water sealing base on the bottom of a gasification chamber; a smoke abatement water sealing is arranged on an outlet from which the gas goes from the gasification chamber to a gas stroing chamber, and dust and sulfide which are mingled with the gas are removed; with the aid of a frequent open flame safety tube by which the gasification chamber and a combustion chamber are connected, the gas pressure in the gasification chamber is slightly higher than the atmospheric pressure in shutdown, so the safety can be ensured and the energy can be saved.

Description

Use producer gas generator more

The utility model relates to a kind of coal consumption of living gas producer, especially a kind of producer gas generators of using more.

Coal is one of main energy sources in people's daily life.At present, modal coal stove all adopts direct coal burning way heat supply on the market, and not only heat utilization efficiency is low, and flue dust is big, and environmental pollution is serious.China utility model patent ZL98235955.1 discloses a kind of coal gasifier, and it is to be made of vapourizing furnace, gasification oven and gas conduit three parts.Though this utility model patent has solved the problem that coal is converted into reignition behind the coal gas, because being flashboard with the Lu Peng bottom, it comes the empty air capacity that enters burner hearth of making, can cause dust pollution, and the bad adjusting of firepower; At furnace shutdown period, the constantly rising of pressure because of coal gas storage room makes coal gas let out from the flashboard of Lu Peng bottom the most at last, causes waste; What this utility model patent was produced in gasification coal is the pollution problem of the obnoxious flavour of major ingredient to air with OS2, does not obtain any solution, and differs widely with the technical program on one-piece construction.

The purpose of this utility model provides and a kind ofly coal is converted into coal gas burns, the heat that discharges in the body of heater is fully used, energy-saving safe, and can make the ashes wet dust removal, immerse in the water, can make the flue dust in the coal gas use producer gas generator more again by being absorbed from what blow-off pipe was discharged by water in the water.

For achieving the above object, the utility model is to realize like this, it is made up of producer gas generator and boiler two portions, the producer gas generator part, mainly be by the water seal base, vaporizer and gas dome constitute, boiler is by the combustion chamber, the boiling water furnace chamber, chimney constitutes, the water seal base is provided with an ash output hole, and attaching has airduct, airduct connects blower fan, the upper end of water seal base is provided with vaporizer, around the vaporizer is water jacket, the one side is provided with a slag notch and a coal filling hole, the opposite side attaching has blow-off pipe, warm water tube, control valve and thermopair, end device has sparger on the vaporizer, and be provided with gas exit, gas exit is socketed with bubble-cap outward, and the vaporizer top is a gas dome, and the gas dome upper end is provided with top pressure closure, one side is provided with a hand hole mouth, and being connected with gas pipe, another side is connected with airduct, upflow tube and filler pipe, the gas dome top arrangement has boiler, bottom side one end of boiler is provided with the spy burner outward, in be provided with the combustion chamber, its intermediate ends is equipped with jet thrust, and connects the gas pipe of gas dome, airduct and normal naked light pipe, the indoor fire tube that is equipped with of boiler, and being connected with boiled water pipe and filler pipe, the top is provided with chimney, enters the ingress of gas dome from vaporizer at coal gas, be provided with a smoke abatement water seal, the OS that coal is produced in gasification ₂With the C that connects the CaO reaction generation in the certain proportion adding coal _aSO ₃, be mixed in after part in the coal gas absorbs by water by water seal the time, from blow-off pipe, discharge.It is isolated that the water seal base is finished the vaporizer bottom and the external world, after the dust that the boiler tube bottom vaporizer is discharged falls into the water, discharges from ash output hole; Air main head to the vaporizer oxygen supply stretches in the water, has prevented that flue gas from blowing back into blower fan.One Chang Minghuo gas pipe is installed between vaporizer and combustion chamber, when blowing out, opens and light.

After adopting such structure, two exits up and down at vaporizer all are provided with water seal, and gasification is carried out under airtight situation fully, and the water seal base has been realized wet dust removal, the smoke abatement water seal makes coal gas obtain purification, has reached clean hygiene effect free from environmental pollution; In addition, can open the Chang Minghuo gas pipe when blowing out, the air pressure that makes vaporizer has not only guaranteed safety just a little more than external pressure, also can not waste energy.
