Abstract
The invention relates to a boiler for conducting sulphur removal and denitration according to the water gas principle. An ash collection box is arranged at the bottom of an inner cavity of a boiler body. A coal ash receiving shell with an upward opening is arranged at the bottom of the ash collection box. A supporting device is arranged between the bottom of the coal ash receiving shell and the bottom of the ash collection box. A coal and water mixture containing area is arranged in the coal ash receiving shell. At least one horizontally-arranged spraying water pipe is arranged above the coal and water mixture containing area at intervals. Compared with the prior art, by means of the boiler, pollutant is removed in the combustion process instead of being processed at a discharge outlet, secondary removing can be conducted in a dust removal set after the reaction and removal are conducted, the processing capacity is better improved, discharged substances are strictly within the standard range of China, the structure is simple, and the implementation cost is low.
Description
Technical field
The present invention relates to the technical field of boiler, especially a kind of boiler by water-gas principle sulphur removal denitration.
Background technology
In known technical field, in recent years, along with the development of science and technology, pollution problem is more and more white-hot, and the concern of people to relevant issues is also more and more higher.The boiler of prior art, because air pollution can be caused will to set up very high chimney, or arranges some sulphur removal denitrification apparatus at exhanst gas outlet.But these devices can not be fully and completely to sulphur removal denitration, can not ensure lower than discharging standards, a lot of pollutant of result has been discharged to underground and sewer, the pollution to soil reclamation, and some pernicious gas has also been discharged in air in the lump, causes air pollution.How using the most succinct method to process emission from boiler, is be worth deeply considering, so researcher is to this has been further investigation.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, provides a kind of boiler by water-gas principle sulphur removal denitration, makes it just can process noxious pollutant at combustion phases.
The technical solution adopted for the present invention to solve the technical problems is: a kind of boiler by water-gas principle sulphur removal denitration, comprise boiler body, dust collecting box is provided with in the bottom of the inner chamber of described boiler body, described dust collecting box is the hollow housing structure of one end open, be provided with opening up coal ash in the bottom of described dust collecting box and accept shell, the cross section that the bottom of shell accepted by described coal ash is semicircular arc, and bracing or strutting arrangement is provided with between the bottom and the bottom of dust collecting box of described coal ash undertaking shell, accept in shell at described coal ash and be provided with coal-water mixture housing region, at least one horizontally disposed spray header is interval with on the top of described coal-water mixture housing region, and the extension direction of the extension direction of described spray header and coal-water mixture housing region is consistent, described spray header is evenly provided with hollow hole.
Further, as a kind of concrete version, bracing or strutting arrangement described in the present invention is bearing block.
The invention has the beneficial effects as follows: the present invention compared with prior art, the present invention clears up pollutant in combustion, instead of at floss hole, it is processed, and after reaction cleaning, secondary cleaning can also be carried out in dedusting group, improve the ability of pollutant process, so the material of discharge is strictly within national standard scope, and structure is simple, implementation cost is cheap.

Fig. 2 is the side view of Fig. 1;
In figure: 1. boiler body, 2. dust collecting box, 3. coal ash accepts shell, 4. bracing or strutting arrangement, 5. coal-water mixture housing region, 6. spray header.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The preferred embodiment of a kind of boiler by water-gas principle sulphur removal denitration of the present invention as depicted in figs. 1 and 2, comprise boiler body 1, dust collecting box 2 is provided with in the bottom of the inner chamber of boiler body 1, described dust collecting box 2 is the hollow housing structure of one end open, be provided with opening up coal ash in the bottom of dust collecting box 2 and accept shell 3, the cross section that the bottom of shell 3 accepted by described coal ash is semicircular arc, and bracing or strutting arrangement 4 is provided with between the bottom and the bottom of dust collecting box 2 of coal ash undertaking shell 3, described bracing or strutting arrangement 4 is bearing block, accept in shell 3 at coal ash and be provided with coal-water mixture housing region 5, at least one horizontally disposed spray header 6 is interval with on the top of coal-water mixture housing region 5, and the extension direction of the extension direction of spray header 6 and coal-water mixture housing region 5 is consistent, spray header 6 is evenly provided with hollow hole.
Principle of the invention process is as follows:
Water is sprayed onto on the coal that falls down in coal-water mixture housing region 5 by spray header 6, and the coal after burning and water are reacted,
Water-gas will be produced after being combined with water by the coal burnt.Shown in the following equation of concrete course of reaction:
H
2O+C＝CO+H
2
After water and carbon react, produce carbon monoxide and hydrogen, after generation hydrogen and carbon monoxide, carbon monoxide can and burner hearth in oxygen reaction; Hydrogen reaction equation is as follows:
2CO+O
2＝2CO

H
2+S＝H
2S
Above-mentioned product hydrogen sulfide can be melted into water, produces hydrosulphuric acid.Coal can produce sulfur dioxide in combustion, and sulfur dioxide meeting wherein and water produce reaction, and reactant reacts with oxygen again, and reflection product is sulfuric acid, and reaction equation is as follows:
SO
2+H
2O＝H
2SO

2H
2SO
3+O
2＝2H

Coal combustion also can generate nitrogen, and nitrogen and oxygen reaction generate nitrogen dioxide, and nitrogen dioxide and water and oxygen reaction will generate nitric acid, and reaction equation is as follows:
N
2+O
2＝2NO
2NO+O
2＝2NO
2
4NO
2+O
2+2H
2O＝4HNO

Containing nitric acid and sulfuric acid in above-mentioned reactant.The iron of two materials meetings and furnace wall reacts, and reaction equation is as follows:
Fe+H
2sO
4=FeSO
4(sediment)+H
2(gas)
3Fe+8HNO
3(rare)=3Fe (NO
3)
2(sediment)+2NO (gas)+4H
2o
By reaching the object of sulphur removal denitration after above-mentioned a series of reflections, and this series reaction is all carried out in burner hearth, and remaining flue gas enters dedusting group and carries out next step purification, is made full use of by discarded flue gas, becomes easy to handle solid-state.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
