Abstract
A kind of solar energy heating coal-burning boiler smoke evacuation system, including being arranged on the flue gas heat-exchange unit in coal-burning boiler chimney smoke exit, being arranged on the solar energy heat conversion device on coal-burning boiler chimney surface, be arranged on the supplementary heating solar energy heat conversion device near coal-burning boiler chimney, and the hot water after solar energy heat conversion device being heated gets to the circulating pump in flue gas heat-exchange unit；Containing a large amount of steam from chimney flue gas out, this part steam pre-cooling immediately condenses into droplet, through flue gas heater region, flue gas is heated, so that the steam in flue gas will not condense immediately thus beneficially pollutant spread and can eliminate visual pollution；Working medium is heated by solar energy heat conversion device, then the working medium after being heated by circulating pump is got in the flue gas heat-exchange unit of chimney top, flue gas is heated is then departed from coal-burning boiler chimney, and the medium after cooling flows back to carry out in solar energy heat conversion device heating again thus forms a circulation.
Description
Technical field
This utility model relates to improving exhaust gas temperature technical field, is specifically related to a kind of solar energy heating coal-burning boiler
Smoke evacuation system.
Background technology
China is coal-fired big country, and coal consumption accounts for the 75% of primary energy total quantity consumed.This directly results in dust and dioxy
Change sulfur emissions huge so that air environmental pollution is extremely serious.Protection environment is the fundamental state policy of China, country for
To the economic and consideration of society's sustainable development, a series of legislations of environmental protection and standard are put into effect, to alleviate environmental pollution and to hold back
Ecological degeneration processed.Along with the environmental regulation of country is the most perfect, the whole supporting flue gas desulfurization device of active service coal unit.?
In common wet desulfurization system, flue gas enters from the bottom of desulfurizing tower, and reaction liquid gets to the top of desulfurizing tower by circulating pump
Portion sprays from specific injection apparatus, and then flue gas flows up, and reaction liquid moves downward with atomised form, thus de-
Sulfur tower occurs chemistry send out and should remove the SO in flue gasX.Owing to flue gas has higher speed, and flue gas and the contact of reactant liquor
Area is relatively big, and the water droplet effect of carrying causing flue gas is obvious, and smoke moisture is greatly increased.
Simultaneously in heat-engine plant wet flue gas desulfurization technique, the flue-gas temperature after absorption tower is washed at 44～48 DEG C, cigarette
Temperature is relatively low, and moisture is substantially at saturation, and the flue-gas temperature processed without wet flue gas desulfurizer is typically 120
More than DEG C.The reduction of exhaust gas temperature can cause atmosphere hoist height to decline, and is unfavorable for that flue gas spreads, and in flue gas, water content is relatively in addition
Easily cause greatly serious visual pollution, Japan and more European countries generally exhaust gas temperature to be heated to more than 80 DEG C and carry out again
Discharge.
Solar energy, as one of the primary developing direction of renewable energy technologies, is the most more and more paid attention to, if
Heat smoke can be added with solar energy and should reach preferable effect.
Summary of the invention
For the problem overcoming above-mentioned prior art to exist, the purpose of this utility model is to provide a kind of solar energy heating
Coal-burning boiler smoke evacuation system, can be effectively improved the exhaust temperature of flue gas, beneficially flue gas and spread and can eliminate visual pollution；Logical
Overregulate the flow of water in entrance heater and can control exhaust gas temperature.
To achieve these goals, this utility model adopts the technical scheme that:
A kind of solar energy heating coal-burning boiler smoke evacuation system, including the cigarette being arranged on coal-burning boiler chimney 1 smoke outlet
Gas heat exchanger 5, be arranged on the solar energy heat conversion device 2 on coal-burning boiler chimney 1 surface, to be arranged on coal-burning boiler chimney 1 attached
Near supplementary heating solar energy heat conversion device 3, and by solar energy heat conversion device 2 and supplementary heating solar energy optical-thermal
Hot water after conversion equipment 3 heating gets to the circulating pump 4 in flue gas heat-exchange unit 5.
Described solar energy heat conversion device 2 and supplementary heating solar energy heat conversion device 3 have heat accumulation function, so
Can ensure that continuous service in night.
It is respectively mounted solar energy heat conversion device 2 on the surface in the east, the south and the west of described coal-burning boiler chimney 1,
And on the vacant lot near coal-burning boiler chimney 1, all it is disposed with supplementary heating solar energy heat conversion device 3.
This utility model system, can strengthen pollutant diffusion and eliminate visual pollution, low-carbon environment-friendly.
Containing a large amount of steam from the flue gas that coal-burning boiler chimney 1 exports out, this part steam pre-cooling is the most solidifying
Forming droplet, this flue gas can be heated through flue gas heat-exchange unit 5 region, flue gas, spreads also such that it is able to strengthen pollutant
And elimination visual pollution, it is to avoid this part steam one goes out chimney and runs into cold air and immediately condense into droplet.
Compared to the prior art this utility model, has the advantage that
The call of response country low-carbon environment-friendly, uses the mode heating boiler smoke evacuation of solar-powered heating, so that boiler
Exhaust gas temperature has a more substantial increase, and on the one hand can obtain higher rising height is conducive to the diffusion of pollutant；The opposing party
Steam in the flue gas of face will not condense immediately, eliminates chimney of electric plant and directly discharges the visual pollution of " white cigarette ".Meanwhile, the sun
Can be that clean energy resource will not produce secondary pollution.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1 is chimney, and 2 is the solar energy heat conversion device arranged on chimney, and 3 is supplementary heating solar energy optical-thermal
Conversion equipment, 4 is circulating pump, and 5 is flue gas heat-exchange unit.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, this utility model is described in further detail.
As shown in drawings, this utility model one solar energy heating coal-burning boiler smoke evacuation system, including being arranged on coal-fired pot
The flue gas heat-exchange unit 5 of stove chimney 1 smoke outlet, be arranged on coal-burning boiler chimney 1 surface solar energy heat conversion device 2,
It is arranged on the supplementary heating solar energy heat conversion device 3 near coal-burning boiler chimney 1, and by solar energy heat conversion device
2 and supplementary heating solar energy heat conversion device 3 heating after hot water get to the circulating pump 4 in flue gas heat-exchange unit 5.
When being embodied as, by being arranged on the solar energy heat conversion device 2 near coal-burning boiler chimney surface and chimney
With supplementary heating solar energy heat conversion device 3, working medium is heated, then by a circulating pump 4, the working medium after heating is got to
In the flue gas heat-exchange unit 5 of chimney top, flue gas is heated when flue gas heat-exchange unit 5 is then departed from coal-burning boiler chimney 1, cooling
After medium flow back to again solar panels be carried out heat thus form a circulation.
Arranging solar energy heat conversion device when, the east, the south be may be arranged at for coal-burning boiler chimney 1 surface
And west, so as much as possible can accept the irradiation of the sun, thus more efficiently convert the solar into heat energy.
