Abstract
The invention provides a plurality of methods for controlling atmospheric pollution, and is used for solving the problem of atmospheric pollution in northern coal-fired areas. The methods are follows: 1. a biomass semi-gasification furnace is adopted so as to achieve more sufficient and complete combustion of combustible gas and higher thermal efficiency, and the combustion products are carbon dioxide and water so as to avoid environmental pollution; 2. a back-burning multi-pass boiler is adopted so that heat is fully utilized after a plurality of flame cycles and most part of smoke dust is deposited so as not to be diffused into air through a plurality of circular paths, thus achieving the purpose of protecting atmospheric environment; 3. biomass fuel is adopted, wherein, biomass energy comes from photosynthesis of plants and is internationally recognized clean energy; and 4. limestone is added to coal for desulfurization, wherein, calcium carbonate is taken as a main component of the limestone and can be heated and decomposed into calcium oxide, and then the calcium oxide chemically reacts with sulfur in the coal so as to generate calcium sulfate, thus playing a role of sulfur retention.
Description
Technical field
The present invention relates to a kind of prevention and control of air pollution method, particularly relate to the method for preventing and treating of the coal-fired regional atmosphere pollution in the north.
Background technology
A universal phenomenon of current society is exactly that a large amount of people in the countryside pour in the city, have for child goes to school, have in order to work, these people's major parts are rented in the one-storey house institute in urban district temporarily, each courtyard all can have three or five families even family more than ten to rent the family.Because the coal reserves of northern China is abundanter, the price of coal is relatively low, so the most coal furnaces that adopt of north of china in winter heating.The a heatable brick bed that make a fire need a chimney; The stove that makes a fire needs a chimney again, and all can there be the chimney of two over-emitting black exhausts in each family like this, and a courtyard is exactly tens such chimneys; Urban and urual areas of whole country have 400,000,000 such chimneys discharging pollutants approximately, cause severe contamination to atmospheric environment.Especially Winter Morning and at dusk, a large amount of dense smoke shrouds the sky in the city, causes very big harm for the people's life, traffic etc., and prevention and control atmosphere pollution have become an extremely urgent major issue.
Summary of the invention
The present invention is directed to above-mentioned situation, the method for several kinds of Air Pollution is provided.
The present invention adopts following technical scheme:
1, use biomass semi-gasification boiler, stove and accessory half gasification, and combustion, make gas fuel burning fully, fully, the thermal efficiency is higher, burning and exhausting is up to standard, environmentally safe.
2, use anti-multi-pass boiler, the stove and accessory of burning, flame is descending, and half gasification, and combustion is abundant; Flame through repeatedly move in circles, backhaul, heat fully is utilized, flue dust is through circulation route repeatedly; The most of deposition can not be dispersed in the atmosphere, protected atmospheric environment.
3, use biomass solid fuel, biomass energy derives from photosynthesis of plants, is internationally recognized clean energy resource, and 1/10th of the not enough coal of sulfur content is a kind of regenerative resource of suitable China's national situation.Turn waste into wealth, energy regeneration, low-carbon energy-saving, benefit the nation and the people.
4, in coal, add limestone desulfurization, the main component of lime stone is a calcium carbonate, and decomposes is a calcium oxide; Sulphur generation chemical reaction in calcium oxide and the coal generates calcium sulfate; Play solid sulphur effect, the sulfur dioxide that is discharged in the atmosphere significantly reduces, and helps improving air quality.
The present invention compared with prior art has following beneficial effect: burning is thorough, and heat utilization ratio is high, and pollutant emission reduces, and reaches discharge standard and improves air quality, control atmosphere pollution.
The specific embodiment
1, use biomass semi-gasification boiler, stove and accessory half gasification, and combustion, make gas fuel burning fully, fully, the thermal efficiency is higher, burning and exhausting is up to standard, environmentally safe.
2, use anti-multi-pass boiler, the stove and accessory of burning, flame is descending, and half gasification, and combustion is abundant; Flame through repeatedly move in circles, backhaul, heat fully is utilized, flue dust is through circulation route repeatedly; The most of deposition can not be dispersed in the atmosphere, protected atmospheric environment.
3, use biomass solid fuel, biomass energy derives from photosynthesis of plants, is internationally recognized clean energy resource, and 1/10th of the not enough coal of sulfur content is a kind of regenerative resource of suitable China's national situation.Turn waste into wealth, energy regeneration, low-carbon energy-saving, benefit the nation and the people.
4, in coal, add limestone desulfurization, the main component of lime stone is a calcium carbonate, and decomposes is a calcium oxide; Sulphur generation chemical reaction in calcium oxide and the coal generates calcium sulfate; Play solid sulphur effect, the sulfur dioxide that is discharged in the atmosphere significantly reduces, and helps improving air quality.
