Abstract
The utility model relates to a steam boiler capable of burning the mixture of coal water slurry and sludge, especially to a coal water slurry steam boiler having water treatment and sludge burning function, which belongs to the steam boiler field. The boiler comprises the following components: a coal water slurry feeding mouth (1), a belt material feeding machine (2), a sludge and quartz sand hopper (3), a star type feeding valve (4), a high pressure air feeding pipeline (5) and a hearth (6). The boiler of the utility model can prevent coke and slag formation, can burn the fuel completely, and has the sludge burning and treatment function; achieves the advantages of simple structure, easy maintenance and low equipment investment. In the boiler, the sludge can be mixed and burned with the coal water slurry directly without drying, thereby the boiler realizes sludge burning, simplifies burning treatment process, and reduces treatment cost. The boiler can burn the burnable substances in the sludge sufficiently, and decompose the pollutants completely, and utilizes the heat energy generated in the organic substance combustion fully, so avoids pollution to the environment; and achieves the advantages of simple structure, convenient and fast maintenance and low equipment investment.
Description
Technical field
The utility model is a kind of water-coal-slurry and mud multifuel combustion steam boiler, belongs to steam boiler.Be particularly related to and have the coal-water slurry steam boiler that water treatment sludge is burned function concurrently.
Background technology
Water-coal-slurry good fluidity, efficiency of combustion height, energy savings, help environmental protection, compare, many superiority are arranged with raw coal fuel.And be used widely.But there is the problem of coking, slagging scorification and incomplete combustion in coal water slurry boiler of the prior art.
The sewage-treatment plant of numerous areas such as papermaking, printing and dyeing, chemical industry, medicine, urban life produces a large amount of mud, the composition more complicated of mud, except that containing moisture, also contain organic matter, various trace elements, pathogenic microorganism and parasitic ovum, the heavy metal etc. of great number of organic matters, difficult degradation.Output is huge, as to form complexity sewage sludge harmlessness, resource are to put water treatment at home and abroad and environmental protection circle personage important topic in front.
The mud of available technology adopting buries the reason method, not only takies the good farmland, and contaminated soil and underground water source; Be not allowed to the rivers,lakes and seas discharging; Burn after drying, not only complex process, processing cost height, and can produce a large amount of NO
x, must dispose tail gas denitrogenation, desulfurizer, the system architecture complexity, equipment investment is high.
The utility model content
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provide a kind of can coking, slagging scorification, fuel combustion is complete, has the burning and processing sludge function concurrently.Simple in structure, easy to maintenance, the water-coal-slurry of low equipment investment and mud multifuel combustion steam boiler.
The purpose of this utility model can reach by following measure:
Water-coal-slurry of the present utility model and mud multifuel combustion steam boiler comprise as lower member: water-coal-slurry material inlet 1, belt filled machine 2, mud and quartz sand hopper 3, star-like feed valve 4, pressure-air charging line 5, burner hearth 6;
Wherein
Described water-coal-slurry material inlet (1) and pressure-air charging line (5) directly communicate with burner hearth (6); Mud and quartz sand hopper (3) communicate with burner hearth (6) by star-like feed valve (4).
1. described mud and quartz sand hopper (3) are to traditional coal-water-slurry boiler quartz sand charging aperture, improve by strengthening the charging area, and it is dual-purpose to make it a bite;
2. described star-like feed valve (4) is improved to star-like valve seal feed-type with the open type feed-type of traditional coal-water-slurry boiler;
3. described pressure-air charging line (5) is newly-installed water-coal-slurry and sludge fuel intensified burning apparatus.
Designer of the present utility model has sprouted development and has had the design concept that water treatment sludge is burned the coal-water slurry steam boiler of function concurrently on the basis of the pure water coal slurry steam boiler of its design.By test repeatedly, former " quartz sand charging aperture " improved, strengthened the charging aperture area, make it possess a bite dual-purpose type function, promptly usual in adding mud usefulness, in the time of necessary also as the quartz sand feed inlet, and change former unenclosed construction, adopt the sealed feed-type of star-like feed valve, improved the burner hearth sealing, boiler thermal output significantly improves.Simultaneously, be aided with suitable high pressure air and be blown into, the mud that adds is fully mixed with oxygen, when mud when red-hot flue gas contacts, the combustible in the mud just can fully burn.Pollutant in the mud decomposes fully, has made full use of the heat energy that organic burning produced, and has avoided the pollution to environment, thereby has finished task of the present utility model.
Water-coal-slurry of the present utility model and the disclosed technical scheme of mud multifuel combustion steam boiler have substantive distinguishing features and obvious improvement compared to existing technology, and can produce following good effect:
1. provide a kind of can coking, slagging scorification, fuel combustion is complete, has the burning and processing sludge function concurrently.Simple in structure, easy to maintenance, the water-coal-slurry of low equipment investment and mud multifuel combustion steam boiler.
2. mud need not be dry, and direct and water-coal-slurry mixed combustion has realized sludge incineration, has simplified burning disposal technology, has reduced processing cost.
3. adopt the sealed feed-type of star-like feed valve, improved the burner hearth sealing, boiler thermal output significantly improves
4. be aided with suitable high pressure air and be blown into, the mud that adds is fully mixed with oxygen, when mud when red-hot flue gas contacts, the combustible in the mud just can fully burn.Pollutant in the mud decomposes fully, has made full use of the heat energy that organic burning produced, and has avoided the pollution to environment,
The utility model boiler have simple in structure, the maintenance convenient and swift, equipment investment reduces significantly.
