Abstract
An Absorption tower comprises a tower body. A gas inlet pipe is arranged paralleled to the tower body and the gas inlet pipe is slant toward the tower at degrees of 35-55 DEG. A reaction tank is arranged under the tower body. A mist separator is arranged at the top of the tower body. A number of fluid sprayers at the tower center are arranged between the reaction tank and the mist separator. Pumps for fluid recycling are connected to the fluid sprayers). The reaction tank are connected with above pumps through pipe.
Description
Technical field
Present invention relates in general to the absorption tower (washing tower) of the entry conductor of improved some component that is used for removing waste gas, relate more specifically to the absorption tower of improved gas inlet duct, wherein the gas inlet duct of tower is connected to tower body obliquely, thereby allows waste gas radially to be evenly distributed in the tower body.
Background technology
In general, at industry and power generation boiler, chemical process equipment contains a large amount of sulfur oxides, nitrogen oxide, things such as floating dust in the waste gas that similar devices such as refuse incinerator produce.For discharging that limits environmental contaminants and the purpose that reclaims them, various technology have been adopted so that from waste gas, isolate one or more above-mentioned components.The absorption tower, it can absorb environmental contaminants in the waste gas when mud drop in the absorption tower contacts at waste gas, is exactly typical case's representative of these technology.For the absorption tower technology, known a kind of spray tower is used for liquid phase material is sprayed into space and a kind of process in the tower by nozzle, wherein is placed with tower tray at the center of spray tower, so that waste gas and absorption liquid are in contact with one another.
As shown in Figure 1, in the absorption tower of routine, gas inlet duct 120 be arranged in parallel with tower body 100 and a vertical side that is connected to tower body 100, in tower body 100, form water-separator 200 and reactive tank 160, upper end at tower body 100 vertically is equiped with gas vent conduit 220, core in tower body 100 inside is provided with a plurality of fluid injectors 140, and fluid injector 140 is linked to each other with liquid circulation pump 180 with 240 ' by pipe 240.
Yet, in the absorption tower of routine, waste gas is from the expand inside that enters tower body 100 and contact with the part inwall of the tower body 100 relative with the outlet of gas inlet duct 120 of gas inlet duct 120, therefore waste gas stream can not be evenly distributed in the tower body 100, thereby has reduced the absorption efficiency on absorption tower.Therefore, in order to increase the distribution area of mud drop and waste gas; Should design the absorption tower bigger, perhaps should use the uniform equipment of exhaust-gas flow.
In addition, have a problem on the absorption tower of routine, that is exactly adopt to prevent that the mud drop from entering the equipment of exhaust gas entrance.
Summary of the invention
Therefore, the problems referred to above that take place in prior art are main points that the present invention pays close attention to, the purpose of this invention is to provide the absorption tower that improved gas inlet duct is arranged, wherein gas inlet duct dips down and tiltedly is connected to tower body, therefore the waste gas that enters the absorption tower is contacted with absorption liquid on the top of tower body, thus distribute equably waste gas by whole absorption liquid with make the waste gas flow path in being evenly distributed in tower.
Another object of the present invention provides the absorption tower of improved gas inlet duct, and it flows downward when making waste gas enter tower body, therefore prevents to enter gas inlet duct from the drop of fluid injector ejection.
In order to achieve the above object, absorption tower provided by the invention comprises tower body; Be arranged in parallel with tower body and be connected to the gas inlet duct of tower body one side with downward-sloping 35 ° to 55 ° angles; Be located at the reactive tank of the bottom of tower body; Be located at the water-separator on the top of tower body; Be located between reactive tank and the water-separator a plurality of fluid injectors in the heart part of tower body; Be connected to the liquid circulation pump of fluid injector; And the pipeline that reactive tank is connected to liquid circulation pump.
Description of drawings
From detailed description, will become apparent above-mentioned and other purpose, feature and other advantage of the present invention below in conjunction with accompanying drawing, in the accompanying drawing:
Fig. 1 is vertical sectional drawing on conventional absorption tower; With
Fig. 2 is the vertical sectional drawing of expression according to the absorption tower of the preferred embodiment of the invention.
The specific embodiment
Fig. 2 is the vertical sectional drawing of expression according to the absorption tower of the preferred embodiment of the invention.In the figure, the gas inlet duct 12 that be arranged in parallel with tower body 10 is connected to a side of tower body 10 with downward-sloping 35 to 55 ° of angles, forms reactive tank 16 and is provided with water-separator 20 on the top of tower body 10 inside in the bottom of tower body 10 inside.
The operation on the absorption tower of said structure is described below.Waste gas enters the inside of tower body 10 by gas inlet duct 12.The waste gas that has entered tower body 10 rises.When waste gas rose, waste gas and the mud that sprays downwards dripped and contact and absorb the pollutant that contains in the waste gas.The drop that has absorbed pollutant rises with waste gas, and shifts out from waste gas by water-separator 20.The waste gas that therefrom shifts out pollutant emits by gas vent conduit 22.
Simultaneously, the drop of sprinkling drops in the reaction tower, is recycled to fluid injector 14 by liquid circulation pump 18 then.In tower body 10, finished such operation of removing pollutant.The removal efficient of pollutant greatly depends on the speed at the waste gas stream of the bottom of tower body 10.Under same operating condition, the waste gas flow velocity is even more in radial distribution, and the efficient of desulfurization and dedusting is high more.
As mentioned above, the invention provides the absorption tower of improved gas inlet duct, it can keep the waste gas flow velocity evenly to distribute.The result, because the exposure level between waste gas on the surface of reactive tank and absorption liquid increases, some component can be removed from waste gas at an easy rate, can increase at the height of removing absorption tower under the certain condition of efficient, because do not need to prevent that waste gas from entering the equipment of gas inlet duct, so the manufacturing cost on absorption tower can reduce, and because the energy cost that can reduce to be used for the pressure of circulating absorption solution body thereby can save the absorption tower.
Though disclose the preferred embodiments of the invention for illustrative purposes, but those of ordinary skill will be understood that in the present technique field, various modifications are added and substitute is possible, and this can not deviate from as disclosed scope of the present invention and aim in the appended claims.
