Abstract
The invention discloses a dedusting boiler with low combustion calorific value, which includes a burning furnace and a steam pot, wherein the burning furnace adopts the structure that a vertical partition is arranged between a rear arch and a front wall above a reciprocating grate and divides the space between the front wall and the rear arch into a hearth and a cyclone dedusting chamber; a feeding opening is arranged at the lower end of the front wall and is opposite to the front end of the reciprocating grate; the reciprocating grate is inclined and provided with a high feed opening end and a low rear end; a front arch inclined to the front end of the reciprocating grate is arranged at the lower end of the partition; a fuel inlet is formed between the front arch and the reciprocating grate and opposite to a feeding nozzle; a flue gas hole is arranged at the upper part of the partition, and is an inclined hole higher at the hearth end and lower at the cyclone dedusting chamber end; the axes of the flue gas hole is tangent to the inner wall of the cyclone dedusting chamber; and a dedusting flue gas pipe is arranged at the top of the cyclone dedusting chamber, and is connected with the steam pot. The combustion dedusting boiler has the function of low combustion calorific value and the significant advantages of harmful gas elimination such as dioxine, and no environmental pollution.
Description
Technical field:
The present invention relates to a kind of burning and fume environment protection draining technology, can eliminate the boiler of bioxin flue gas and burning low-heat material especially.
Background technology:
Existing boiler generally is a stove and pot is an overall structure with stove, and the boiler of this structure generally can not lower heat of combustion fuel, and reason is, the gas temperature that is produced by the low calorie fuels burning is lower, in pot, is cooled off by the heat absorption wall of pot again, makes the burning can't normal combustion; Another major defect of existing low heat value boiler is that De bioxin gas can't be eliminated in the flue gas, causes environmental pollution.
Summary of the invention:
The object of the invention provides a kind of existing lower heat of combustion fuel has a kind of low heat value burning dust removal boiler of eliminating the bioxin pernicious gas again.
The technical scheme of the object of the invention is; Comprise combustion furnace and steam copper; It is characterized in that: the structure of said combustion furnace is, the spatial between antetheca and the rear arch is divided into burner hearth and cyclone dust removal chamber being provided with vertical partition wall between rear arch above the reciprocal grate and the antetheca, and the front end that the lower end of antetheca is provided with dog-house and reciprocal grate is relative; Said reciprocal grate is the fire grate of the low inclination in the high rear end of feed inlet end; The lower end of said partition wall is provided with the face arch to the inclination of reciprocal grate front end, and it is relative with above-mentioned dog-house to form fuel inlet between this face arch and the reciprocal grate, and the top of said partition wall is provided with smoke hole; This smoke hole is burner hearth end height and the low inclined hole of cyclone dust removal chamber end; The inwall of the axis of this smoke hole and cyclone dust removal chamber is tangent, establishes dedusting at the top of said cyclone dust removal chamber and goes out fume pipe, and this goes out fume pipe and is connected with said steam copper.The gradient of the smoke hole on said partition wall top is the 2-5 degree.Top, said cyclone dust removal chamber is provided with goes out fume pipe, and the 0.5-0.75 that this distance that goes out lower port to the dirt pocket top board inner surface of fume pipe is a cyclone dust removal chamber equivalent diameter doubly.The present invention and prior art more not only have the function of lower heat of combustion but also have the bioxin pernicious gas of elimination remarkable advantage free from environmental pollution.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
In order to use low calorie fuels, plant fuel like biology, especially combustible rubbish (calorific value is lower) takes stove and the pot measure of being separated to make the interior temperature of stove not receive the influence of cold water wall in the pot; In order to solve in cyclone dust collectors De bioxin in the flue gas is removed; According to bioxin in the principle that promptly is decomposed more than 2 seconds more than 850 ℃; The structure of low heat value combustion furnace and the structure of cyclone separator are designed; Its concrete structure is following; Be divided into burner hearth 3 and cyclone dust removal chamber 9 between with rear arch and antetheca being provided with vertical partition wall 5 between rear arch above the reciprocal grate 12 and the antetheca 8, be provided with dog-house 10 in the lower end of antetheca relative with the front end of reciprocal grate, and this reciprocal grate is the low inclined grate in the high rear end of feed inlet end; The lower end of partition wall is provided with a face arch 4 that tilts to the reciprocal grate front end, and it is relative with above-mentioned dog-house to form fuel inlet 11 between this face arch and the reciprocal grate.Be provided with dedusting at the top of above-mentioned dirt pocket and go out fume pipe 7, this bottom of advancing fume pipe places in the above-mentioned dirt pocket, has smoke hole 6 on the top of above-mentioned partition wall, and the axis of this smoke hole and the inwall of above-mentioned dirt pocket are tangent.The operation principle of above-mentioned low heat value combustion furnace is; Low calorie fuels (straw or flammable house refuse) enters reciprocal grate upper edge fire grate from dog-house and is rolled at fire grate to the rear end by front end and fully burn; Can produce a large amount of flue gases and dust in smoke hole entering dirt pocket, in dirt pocket, rotate at a high speed, make that dust in flue gas is centrifugal to be dropped on the fire grate along inwall; Discharge through ash hole, realize dedusting.In order to remove De bioxin in the flue gas, burner hearth is optimized the ignition temperature that design improves burner hearth, make temperature Da bioxin decomposition temperature more than 850 ℃; The time that reaches decomposition for the Shi bioxin is more than 2 seconds; Therefore the smoke hole to above-mentioned partition wall upper end is designed to downward-sloping hole, makes the flue gas of high temperature enter the middle and lower part of dirt pocket, and what make the dirt pocket top simultaneously goes out 0.5-0.75 that the distance L of fume pipe in dirt pocket be generally cyclonic separation dirt pocket equivalent diameter doubly; The time that flue gas is burnt away in dirt pocket was not less than for 2 seconds; Through test, the angle of inclination of the smoke hole of above-mentioned inclination is 2-5 ° is advisable, and can remove De bioxin in the flue gas.Above-mentioned high-temperature fuel gas enters in the water wall the pot from fume pipe through after the dedusting, can produce steam or hot water.
