Fig. 1 is structural representation of the present invention;
Fig. 2 is that gas-liquid of the present invention moves towards schematic diagram;
Fig. 3 is three-dimensional structure diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing citing, the present invention is described in more detail:
Composition graphs 1 ~ 3, the present invention mainly forms and comprises exhaust gases passes 1, heat exchange of heat pipe (comprising condensation section 6, adiabatic section 5 and evaporator section 2), water injector 3, gas-liquid separation device 4, solution catcher 8, atomization crystallization apparatus 7 etc.Heat exchange of heat pipe condensation section 6, water injector 3 and gas-liquid separation device 4 is arranged successively by the flow direction of air-flow in gas flue.After the evaporator section 2 of the heat exchange of heat pipe by parallel heating pipe bank composition, flue-gas temperature reduces, and condensation appears in steam wherein, and discharging pollutants in partial fume is dissolved among water smoke.Flue gas is when by water injector 3, and the water smoke of ejection dissolves and more discharges pollutants; Last flue gas is by carrying out gas-liquid two-phase separation during gas-liquid separation device 4.The isolated liquid of gas-liquid separation device 4 under gravity, is collected in the solution catcher 8 being placed in its lower end.Solution in solution catcher 8 enters atomization crystallization apparatus 7 by pump through pipeline, after high-pressure nozzle atomization, forms the droplet of atomization.Drop is after the heat absorbing the transmission of heat exchange of heat pipe evaporator section 2, and water evaporates wherein, reaches satiety and crystallization.Crystalline particle falls to be separated under gravity.The steam formed in evaporation process can be condensed into water, uses as boiler water cycle.
Evaporator section 2 is placed in exhaust gases passes, and condensation section 2 extend in the heating clamber of atomization crystallization apparatus 7, and condensation section 2 is in being staggered.The condensation section 6 of heat exchange of heat pipe is higher than evaporator section 2.Gas-liquid separation device 4 is flap separator, is provided with the solution catcher 8 of a collection sewage below it.Atomization crystallization apparatus 7 includes high-pressure nozzle and steam draws pipeline, valve etc., is provided with a high pressure spout carries out atomization process to the sewage entered wherein at its entrance.The steam outlet being simultaneously atomized crystallization apparatus 7 can arrange a condenser, cools steam.Exhaust gases passes 1 and atomization crystallization apparatus 7 are generally arranged nearby.The condensation section 6 of atomization crystallization apparatus 7 is higher than evaporator section 2.
The course of work of the present invention:
Composition graphs 1 and Fig. 2, containing steam, air, CO in the high-temperature flue gas that burning is discharged 2, SO x, NO xetc. component, also containing a small amount of dust.When flowing through gas flue and being provided with the leading portion of parallel heating pipe bank evaporator section, the temperature of flue gas reduces rapidly, and reach condensation point, steam wherein condenses into droplet, and the oxysulfide in flue gas is dissolved in and wherein forms acid drop.When by water injector, the water smoke be ejected that discharges pollutants dissolves further; At the back segment of gas flue, flue gas carries out gas-liquid two-phase separation in gas-liquid separation device under the effect of inertia.Isolated liquid under gravity, is collected in the solution catcher be placed in below it.Solution in solution catcher enters atomization crystallization apparatus by pump through pipeline, after high-pressure nozzle atomization, form droplet.Drop is after the heat absorbing the transmission of heat exchange of heat pipe evaporator section, and water evaporates, reaches satiety and crystallization.Then, crystalline particle falls under gravity and is separated.The steam formed in the evaporation process of atomization crystallization apparatus can be condensed into water, uses as boiler water cycle.
In heat exchange of heat pipe, working solution absorbs the heat vaporization in flue gas at heat pipe evaporator section, at the flows by action of pressure reduction to the other end.Meanwhile, the working solution of vaporization condenses at condensation segment, is back to evaporator section, reuptakes heat under the double action at capillary suction force and gravity.
