Abstract

The utility model discloses a novel environmental protection boiler with boiler internal smoke and dust abatement clean burning. The novel environmental protection boiler comprises a water tube boiler body, a fire tube boiler body, or a water-fire tube combination type boiler body, a fire grate, a coal loading hopper, a boiler front arch, a boiler back arch, a fire door, a water seal slag removal port, an inverted-hook-shaped fire barrier provided with a semi-closed upper part and a semi-closed lower part, and disposed between the boiler front arch and the boiler back arch, and a water coking cleaning device disposed at the end of the fire grate. The novel environmental protection boiler is advantageous in that, the defects of high fuel cost, high operation cost, and overhigh cost of boiler external smoke and dust abatement of an environmental protection boiler in the prior art are overcome, the temperature of a whole hearth is greatly improved, the carbon content of ash is made to be ultra-low, the thermal efficiency of the boiler and the fuel utilization rate are effectively improved, and the purposes of smoke and dust abatement, energy saving, and environment protection are achieved.

Description

Smoke elimination dust elimination purification of combustion environment-protection boiler in a kind of Novel furnace

Technical field

The utility model relates to a kind of boiler, specifically smoke elimination dust elimination purification of combustion environment-protection boiler in a kind of Novel furnace.

Background technology

The smoke abatement and dust control overwhelming majority of the loose coal burning boiler of burning all arranges with rear end that dedusting completes in the market.Deduster major function is dedusting, and smoke elimination rate is low.Outside the gases such as the carbon dioxide that loose coal combustion produces, steam, oxynitrides, hydrocarbon, carbon monoxide, sulfur dioxide, hydrogen sulfide, also produce flying dust, flying dust refers to that fuel is in combustion process, the soot particle of being taken out of by high-temperature gas and unburnt thin buckwheat coal etc.Because carbon blacks and flue gas have produced black smoke in a large number.Cigarette refers to black smoke, by a large amount of carbon blacks and flue gas, is formed.Carbon black is because fuel is when imperfect combustion, and high-molecular hydrocarbons wherein decomposes and produces the in the situation that of high temperature anoxic, and wherein the imperfect combustion gas such as hydrocarbon, carbon monoxide and unburnt coal grain, carbon black etc. are combustible.Coal ignited the fugitive constituent in coal under trimmer arch radiant heat in the past, flame is natural in backlash under the effect of boiler induced-draft fan by surface, coal seam, the fugitive constituent, carbon black and the solid particle that wherein have major part not ignited, also with flame, together alter backward, with the flue gas black smoke of emerging that together discharges out of the furnace.Such material is not fully burned and is discharged from outside stove, wastes energy and contaminated environment.Present stage market, to the large multi-steering water coal slurry combusting technology of the research of coal-burning boiler technique for smoke, gas reforming technology, Semi-gas burning etc.For many years for the rare appearance of smoke abatement and dust control new technique in the burner hearth of boiler self.

Summary of the invention

In order to solve the problem of above-mentioned existence; the utility model provides smoke elimination dust elimination purification of combustion environment-protection boiler in a kind of Novel furnace; it has improved the utilization rate of boiler thermal output and fuel effectively, ash content carbon is down to extremely low, the object that reaches smoke elimination dust elimination protection of the environment and save the energy.

The purpose of this utility model is achieved through the following technical solutions:

Smoke elimination dust elimination purification of combustion environment-protection boiler in a kind of Novel furnace, comprise boiler body, fire grate, upper coal bunker, trimmer arch, stove rear arch, fire door, water seal is except cinder notch, and the semi-enclosed barb type firebreak in semiclosed bottom, top is arranged between trimmer arch and stove rear arch, and water coking purifier is arranged on fire grate end.

Described boiler body is any one in water-tube boiler, multitubular boiler, water-fire pipe composite boiler.

The beneficial effects of the utility model: smoke elimination dust elimination purification of combustion environment-protection boiler in Novel furnace, by barb type firebreak is set between face arch in burner hearth and rear arch, fire grate end arranges water coking purifier; Barb type firebreak adopts the semi-enclosed interior excess Temperature of burner hearth that prevents in top, after burning by high temperature circulation, the outlet of high-temperature flue gas by semiclosed barb type firebreak bottom, semiclosed bottom, top enters the latter half of heated body that makes in stove and is heated, dust and the slag spray by fire grate end water coking purifier makes the lime-ash coking of stoker surface form solid-state lime-ash with fire grate, to move and discharge out of the furnace, reach real smokeless and dust free purification of combustion; This stove has overcome environment-protection boiler fuel cost of the prior art, operating cost is high and the defect such as the outer smoke elimination dust elimination of stove mode high cost; whole fire box temperature is significantly improved; ash content carbon is extremely low; effectively improve the utilization rate of boiler thermal output and fuel, reached the object of smoke elimination dust elimination, the saving energy, protection of the environment.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, smoke elimination dust elimination purification of combustion environment-protection boiler in a kind of Novel furnace, this device is on the basis of grate furnace, the boiler body 4 that comprises water-tube boiler, multitubular boiler or water-fire pipe composite boiler, fire grate 3, upper coal bunker 1, trimmer arch 2, stove rear arch 8, fire door 6, water seal is except cinder notch 9, boiler exterior wall 10, the semi-enclosed barb type firebreak 5 in semiclosed bottom, top is arranged between trimmer arch 2 and stove rear arch 8, and water coking purifier 7 is arranged on fire grate 3 ends.

When the transformation of coming of new and old boiler, all can between the inner of the boiler chamber face arch 2 of boiler front end setting and stove rear arch 8, the semiclosed barb type firebreak 5 in semiclosed bottom, top be set, by stopping of the top semiclosed barb type firebreak 5 in semiclosed bottom, flame cannot pass through from top, by semiclosed barb type firebreak 5 refractions in semiclosed bottom, top, combustible in flame and solid combustible particle are thrown on the fire bed of fire grate 3, flame can only pass through from the semiclosed uncovered barb type firebreak 5 of the semiclosed uncovered upper outlet in top and bottom in outlet, reach circulating combustion, afterwards on top, semiclosed barb type firebreak 5 front ends in semiclosed bottom form high-temperature region, make the iterative cycles burning in high-temperature region of combustible and solid combustible particle, barb type firebreak 5 adopts the semi-enclosed interior excess Temperature of burner hearth that prevents in top, after burning by high temperature circulation, the outlet of high-temperature flue gas by semiclosed barb type firebreak 5 bottoms, semiclosed bottom, top enters the latter half of heated body that makes in stove and is heated, dust and the slag spray by fire grate 3 end water coking purifiers 7 makes the lime-ash coking on fire grate 3 surfaces form solid-state lime-ash with fire grate 3, to move and discharge out of the furnace, reach real smokeless and dust free purification of combustion.The quick operation of this stove by fuel and air-flow and suspension, vaporization, really realized efficient, energy-conservation; This stove in the running, increases the burning zone of fuel, and the time of staying extends, and burn-off rate improves, and fume emission is without black smoke; During this stove running, calandria is heated evenly, heating surface area is large, and temperature rises fast, and the thermal efficiency is high, has really arrived the object of smokeless and dust free purification of combustion.
