Description
Technical field
The utility model relates to the improvement of the hot purified gas producer of a kind of low heat value structure.
Background technology
At present, in the heating gas that the producer gas generator of domestic operation is produced, contain coal tar usually, coal tar not only influences the thermo-efficiency of coal gas, and coal tar is easy on inside pipe wall and the nozzle, has influenced the trouble-free burning of kiln heating.
And two stage type gas generating furnace bulky (high about 16m) is provided with complicated refining plant for removing tar, and the phenol in the wash water after the purification must be through processing again, just can discharge after up to standard, and production brings very big inconvenience to coal gas.Though the coal tar in the coal gas has obtained purification,, a large amount of heat energy has been lost in the reduction of gas temperature again.In addition, the combustiblesubstance in the coal tar is all wastes after treatment, have reduced the rate of combustion of coal.
In addition, existing producer gas generator for coal gas is extracted out, is provided with cavity usually in producer gas generator, the coal gas in the cavity in case with the air thorough mixing, reach explosion condition and just can explode at once, bring very big hidden danger to safety in production.
The utility model content
The utility model is exactly to the problems referred to above, and a kind of hot purified gas producer is provided.
For reaching the above-mentioned purpose of the utility model; The utility model adopts following technical scheme: the hot purified gas producer of the utility model comprises the body of heater that is made up of upper furnace body and lower furnace body; The lower furnace body bottom is a fire grate; Be provided with first blast pipe corresponding to fire grate, the outside diameter of the described upper furnace body of its structural feature is less than the interior diameter of lower furnace body, and upper furnace body is outer, and vertical opening setting has the midbody that coal gas goes out pipe corresponding to lower furnace body; Coal gas goes out pipe and links to each other with dust-precipitator; The upper furnace body middle part is provided with and is communicated with intravital second blast pipe of stove, and the coal inlet place of body of heater top is provided with feeder; Described first blast pipe links to each other with the air outlet of second blast pipe with the wind vapour mixing bellows chamber that links to each other with steam-generating installation.
The beneficial effect of the utility model: 1, the hot purified gas producer of the utility model hot purified gas of low heat value that can produce no coal tar; Both avoided coal tar to be prone to attached on inside pipe wall and the nozzle; Reach coal gas itself again and had the purpose of heat; Guarantee the thermo-efficiency of coal gas, practiced thrift the energy; In addition; The hot purified gas producer of the utility model need not to use in the existing installation for removing the complicated treating plant that coal tar uses; Reduced production cost, its compact construction, volume are compared greatly with existing two stage type gas generating furnace and are reduced (the utility model is merely 9.6m).
2, the utility model makes coal cinder intensification in the body of heater, and forms the reducing zone that is made up of hot charcoal piece through the coal cinder in the lower furnace body is lighted; Again coal gas is gone out pipe and apply negative pressure, by the coal tar that coal cinder produces after lighting, CO
2With hydrocarbon compound etc., all pass through reducing zone, and when going out pipe and discharge by coal gas, coal tar, CO
2, hydrocarbon compound etc. and water vapour, carbon reaction, generate CO and H
2, after dust-precipitator is handled, just form purified coal gas with certain calorific value, reach the purpose of simplified apparatus, save energy and raising thermo-efficiency.
3, because the utility model when producing hot purified gas, is filled coal cinder in body of heater, do not have cavity, and the cooperation through upper furnace body, lower furnace body and midbody makes the intravital flue gas of stove uniformly by sucking-off; Therefore, the intravital inflammable gas of stove can't mix in enough spaces with air, does not have explosion condition, has also just avoided the generation of explosion phenomenon, reaches purpose safe and reliable to operation.
