Technical field
What the present invention relates to is a kind of tapping equipment that reduces fume emission.
Background technology
Boiler in the equipment such as engine, contains SO in the flue gas that the fossil energy burning produces
x, NO
xDeng pollutant, directly discharging can cause atmosphere pollution, does not process simultaneously the acid dew piont corrosion phenomenon also easily to occur in exhaust gases passes.If flue gas is not added directly discharging of processing, not only can produce atmosphere and pollute, be also waste for the heat in about high-temperature flue gas (150 ℃).
At present, obtained remarkable progress for flue gas pollutant processing and control technology, method commonly used has: use in alkaline matter and acid gas in flue gas, flue gas desulfurization is purified; Also have in addition strong adsorbability materials such as using NACF to carry out physical absorption to pollutant in flue gas and process, although above method has in research and uses, also be restricted, such as complex process, when flue gas flow is larger, treatment effeciency is low etc.Flue gas pollutant removal method in patent 200910062370.7 is the active carbon carbon fiber, has adopted simultaneously the I and II reactor, and at first flue gas passes through after cooling in turn, the discharging after heating again of charcoal absorption pollutant wherein, the flue gas after purification.Because the adsorption capacity of active carbon own is limited, and there is saturated problem, just need to removes product by the water spray washing here, complex process, and also the smoke treatment flow is little.Gas cleaning discharging integration apparatus in patent 200820155469.2 is applied to sulfur removal technology in gas cleaning, do not need former chimney is transformed, but its equipment occupation space is large, and the equipment costs such as insulation are more, are only applicable to the large-sized boiler smoke evacuation.
Summary of the invention
The object of the present invention is to provide to solve that fume emission treatment system space is large, treatment effeciency is not high a kind of tapping equipment that reduces the flue gas pollutant discharging of the problems such as complex process.
The object of the present invention is achieved like this:
a kind of tapping equipment that reduces the flue gas pollutant discharging of the present invention, it is characterized in that: comprise exhaust gases passes, the atomizing crystallization apparatus, heat exchange of heat pipe, heat exchange of heat pipe comprises the evaporator section that is connected successively, the adiabatic section, the section of condensing, evaporator section is positioned in exhaust gases passes, the section of condensing is positioned in the atomizing crystallization apparatus, the adiabatic section is between exhaust gases passes and atomizing crystallization apparatus, in exhaust gases passes, the rear of evaporator section sets gradually water injector and gas-liquid separation device, gas-liquid separation device is communicated with solution catcher, solution catcher is communicated with the entrance of atomizing crystallization apparatus by pipeline and pump, the entrance of atomizing crystallization apparatus is provided with high-pressure nozzle.
The present invention can also comprise:
1, the described section of condensing interlaced arrangement is in the atomizing crystallization apparatus, and higher than evaporator section.
2, the outlet of atomizing crystallization apparatus arranges the solution memory.
Advantage of the present invention is: the present invention can effectively reduce the temperature of high-temperature flue gas, reduces exhaust to the pollution of atmosphere, has simultaneously the upstream airflow impact littlely, and power consumption less, efficient is high, integrated level is high, the advantage such as little takes up room.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is that gas-liquid of the present invention is moved towards schematic diagram;
Fig. 3 is three-dimensional structure diagram of the present invention.
The specific embodiment
For example the present invention is described in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～3, chief component of the present invention comprises exhaust gases passes 1, heat exchange of heat pipe (comprising the section of condensing 6, adiabatic section 5 and evaporator section 2), water injector 3, gas-liquid separation device 4, solution catcher 8, atomizing crystallization apparatus 7 etc.Flow direction by air-flow in gas flue is being arranged the heat exchange of heat pipe section of condensing 6 successively, water injector 3 and gas-liquid separation device 4.After the evaporator section 2 of the heat exchange of heat pipe that forms by parallel heating pipe bank, flue-gas temperature reduces, and dewfall appears in steam wherein, and discharging pollutants in partial fume is dissolved among water smoke.Flue gas is by water injector 3 time, and the dissolving of the water smoke of ejection more discharges pollutants; Last flue gas carries out gas-liquid two-phase by gas-liquid separation device 4 time separates.The isolated liquid of gas-liquid separation device 4 is collected in the solution catcher 8 that is placed in its lower end under action of gravitation.Solution in solution catcher 8 enters atomizing crystallization apparatus 7 by pump through pipeline, after the high-pressure nozzle atomizing, forms the droplet of atomizing.Drop is after the heat that absorbs 2 transmission of heat exchange of heat pipe evaporator section, and water evaporates wherein reaches satiety and crystallization.Crystalline particle descends to be separated at Action of Gravity Field.The steam that forms in evaporation process can be condensed into water, uses as boiler water cycle.
The course of work of the present invention:
In conjunction with Fig. 1 and Fig. 2, contain steam, air, CO in the high-temperature flue gas that burning is discharged
2, SO
x, NO
xEtc. component, also contain a small amount of dust.When the gas flue of flowing through was provided with the leading portion of parallel heating pipe bank evaporator section, the temperature of flue gas reduced rapidly, reached the dewfall point, and steam wherein condenses into droplet, and the oxysulfide in flue gas is dissolved in and wherein forms acid drop.By water injector the time, the water smoke that is ejected that discharges pollutants further dissolves; At the back segment of gas flue, flue gas carries out gas-liquid two-phase under the effect of inertia in gas-liquid separation device separates.Isolated liquid is collected in the solution catcher that is placed in its below under action of gravitation.Solution in solution catcher enters the atomizing crystallization apparatus by pump through pipeline, forms droplet after the high-pressure nozzle atomizing.Drop is after the heat that absorbs the transmission of heat exchange of heat pipe evaporator section, and water evaporates reaches satiety and crystallization.Then, crystalline particle is separated in Action of Gravity Field decline.The steam that forms in the evaporation process of atomizing crystallization apparatus can be condensed into water, uses as boiler water cycle.
In heat exchange of heat pipe, working solution is vaporized at the heat that heat pipe evaporator section absorbs in flue gas, flows to the other end under the effect of pressure reduction.Simultaneously, the working solution of vaporization condenses at condensation segment, be back to evaporator section under the double action of capillary suction force and gravity, reuptakes heat.
