Description

A kind of full gasification counter-combustion energy-saving cooking stove
Technical field
This utility model is related to a kind of coal stove, more particularly to a kind of full gasification counter-combustion energy-saving cooking stove.
Background technology
Up to 700,000,000, wherein decentralized heating population 200,000,000, about 6000 ~ 65,000,000 families determine to fire at present China's heating population Civil heating stove and small atmospheric hot-water boiler based on coal is by long-term existence.Common stove rough coal burning, the thermal efficiency only have 20% ~ 40% or so, while a large amount of dense smokes of discharge, cause the problems such as high energy consumption, poor efficiency, atmospheric pollution, subject matter to show ?:
1st, agricultural at present cook a meal radiator while heating in order to solve the problems, such as cooking, all using fire coal just burning pattern, i.e., All coal-fired in burner hearth is burnt simultaneously, and completely by coal amount how much controlling, plus new coal burns in half combustion firepower to prosperous Sulfided state is burnt, a large amount of dense smokes are discharged, prosperous burning with half burning alternately, causes to burn insufficient, and ashes phosphorus content is high, up to not To the effect that burns completely, utilization rate of coal is low.
2nd, the scattered coal that rural area is burnt is based on bituminous coal, mostly of poor quality, and the discharge capacity such as flue dust, sulfur dioxide is high, poorly efficient stove Gasifier gasification stroke is short, and a large amount of flue gases produced during fired coal combustion can not be fully vaporized prior burning, multiple harmful gas in flue gas Body is directly discharged, and causes atmospheric pollution, while producing thick coal tar in a large number, is attached on smoke box and water jacket, is removed tired Difficulty, has a strong impact on heat transfer effect, and the longer heating effect of stove service life is poorer.
3rd, radiator of cooking a meal can produce substantial amounts of CO (carbon monoxide converter) gas under the state of banking up a fire, by the bell that can not fully seal and Chimney is leaked in air, is easily caused user's coal gas " poisoning ", is jeopardized the life of people, there is personal safety hidden danger.
4th, the high temperature hyperpyrexia stove fire and flue gas of common stove burning is directly discharged to air by single flow flue through chimney, At one meter, typically at 190 DEG C or so, outlet flue temperature is higher for stack temperature, and the non-secondary recovery of heat is utilized, and causes amount of heat It is lost in.
5th, after common stove, smoke box is the hot water jacket direct-connected with burner hearth, and the temperature difference is little between high-temperature flue gas, and heat transfer effect is poor, High temperature hyperpyrexia flue gas heat can not be fully utilized, and reduce heat utilization efficiency.
Utility model content
This utility model provides a kind of discharge for improving utilization rate of coal, reducing dusty gass, extends the use year of stove The full gasification counter-combustion energy-saving cooking stove of limit, it is proposed that following technical scheme:
A kind of full gasification counter-combustion energy-saving cooking stove, including a body of heater, the furnace interior is provided with coal-firing device and changes Thermal, the coal-firing device include energy-saving gasification device and high temperature fire-assembling tube from top to bottom successively, and the energy-saving gasification device is also An independent air distribution outlet is provided with, the heat-exchanger rig includes one with the double return flues connected at the top of coal-firing device, the double back An independent smoke box cold water jacket is provided with inside journey flue.
Further improvement of these options, the energy-saving gasification device design growth barrel shape.
Further improvement of these options, " " shape structure of the described pair of return flue in side, the coal combustion dress It is set in the right of described pair of return flue.
Further improvement of these options, the body of heater are provided with a coal filling hole.
The beneficial effects of the utility model are:
(1)This utility model solves the problems, such as the coal-fired anti-cooking function of burning pattern of radiator of cooking a meal using high temperature fire-assembling tube, In combustion process, in burner hearth, fire coal from bottom to top successively burns, and reaches the purpose that burns completely.Without the need for manual dust unloading, coal-fired complete Automatically fall after full burning, only generation little power shape ashes, volume less than raw coal volume a thirtieth, phosphorus content is basic It is zero.Because burner hearth burns pattern for anti-, so coal does not affect cooking firepower, cooking state not cutoff, fire coal to remain prosperous burning State, and will not produce thick smoke during coal, reduce environmental pollution.
(2)Long cartridge type gasifier increased the vaporization time of flue gas, make substantial amounts of high-temperature flue gas carry out the burning that is gasified totally, Cooking firepower is increased, Air Pollutants Emissions is reduced again, while make coal tar burn completely, on smoke box and water jacket only Micro black powder is produced, substantially without deashing, heat transfer effect is improve.
(3)Gasifier air distribution outlet is completely independent, and either prosperous burning state is still banked up a fire state, and gasifier abundance makes cigarette with oxygen Gas remains that naked light burns, and greatly reduces CO emission.
(4)Double back journey Flue duct design increased high-temperature flue gas heat-exchange time and flow process into " " structure of side, make high temperature The heat effective recycling of flue gas and smoke box are increased the temperature difference with the high heat smoke of high temperature, are made using independent cold water nested structure The heat exchange of flue gas heat and water jacket more fully, lifts heat utilization ratio again, and radiator entirety of the cooking a meal thermal efficiency is up to more than 70%
