A kind of gas cleaning plant and method
Affiliated field: the present invention relates to a kind of gas cleaning plant and method.
Background technology: Chinese patent discloses a kind of gas cleaning plant, its [application number] is 01217733.4, and it mainly comprises housing, and lower housing portion is provided with air inlet, also be provided with bracing frame, fluid sphere layer, spray thrower and dehydrator in the housing, spray thrower is made up of pipeline and spray head; Described spray head is arranged by at least two tubaeform sheet separations and is formed, and tubaeform plate bottom centre all offers through hole, and bottom centre's through hole of outermost tubaeform plate is connected with seal for pipe joints; The disclosed technology of this patent is that the shower water by spray thrower purifies the gas that enters housing, and the water to spray can not fully contact behind the housing because gas enters, and therefore influences gas cleaning efficient.
In addition, Chinese patent also discloses the gas cleaning plant of another kind of structure, its [publication number] is 2366749, the disclosed technology of this patent is by be provided with an oval column filter in contactor, the cylindrical filter styletable communicates with outlet pipe, also is provided with a strip ultraviolet generater in the inner side of contactor.Its existing problem is that cylindrical filter is often wanted artificial cleaning or artificial the change; The 2nd, it is very big that purification efficiency is influenced by the cylindrical filter material, complex process.
The 3rd technology that the present invention contrasted is the disclosed a kind of gas cleaning plant of Chinese patent equally, its [publication number] is 2480046, this device has a shell 1, shell 1 is provided with air inlet pipe 2 and blast pipe 3 and seal cover 6, air inlet pipe stretches in the shell, and extends to below the liquid level, and the liquid 4 of a constant volume is housed in the shell, on the dividing plate 7 between liquid level and the blast pipe filter 5 is housed, filter is made by Sponge or active carbon.This technology adopts separation and filters the mode that combines flue gas is carried out purification filtering, and it still exists the problem that often needs artificial change Sponge or active carbon.
Summary of the invention: the objective of the invention is to design a kind of purifying rate height, gas cleaning plant simple to operate.
The object of the present invention is achieved like this, design a kind of gas cleaning plant and method, it comprises tank body, is connected admission line, gas outlet on the tank body, inlet and liquid outlet, it is characterized in that: be distributed with qi-emitting hole on the admission line in tank body, be used for and enter in jar interior even cloth tank body of gas; In tank body, be fixed with Liqiud-gas mixing device.
Described Liqiud-gas mixing device is the float valve that is fixed on the plate.
Described Liqiud-gas mixing device is a bell jar.
The gas purification mode is: add liquid by inlet, liquid side is controlled on the Liqiud-gas mixing device, gas is by behind the admission line, enter in the liquid by being fixed in subsurface perforation gas distribution pipe, because specific gravity of gas is light, in liquid, constantly rise, in uphill process, constantly collide and contact, adsorb, adhere to washing with fluid molecule; Finish first step washing process; Gas further mixes with air and liquid mixer under being fixed in also face in the time will reaching liquid side, and gas is washed once more, finishes washing process for the second time, and the gas of purification is discharged from the gas outlet again; In gas purification process, impurity that gas is with can be trapped within the liquid, finishes the purpose of changing liquid by the valve of control liquid outlet, to guarantee the cleaning in the tank body.
The present invention is owing to be divided into two processes with gas purification, can make the liquid mist in the gas that enters in the tank body and adhere to impurity and fully be contacted with liquid, impurity is fully contacted with liquid, make impurity absorption, stick in the liquid, realize the high purpose of purifying rate, liquid in the tank body can regularly replace, and guarantees to be deposited in the timely drain tank external body of impurity in the liquid.
The present invention will be further described below in conjunction with implementing accompanying drawing.
Description of drawings: Fig. 1 is the embodiment of the invention 1 structural representation;
Fig. 2 is the embodiment of the invention 1 structural representation.
Among the figure, 1, tank body; 2, admission line; 3, gripper shoe; 4, liquid level; 5, mist eliminator; 6, gas outlet; 7, Liqiud-gas mixing device; 8, leakage fluid dram; 9, qi-emitting hole; 10, inlet; 11, float valve; 12, bell jar.
Embodiment: Fig. 1 is the structural representation that Liqiud-gas mixing device adopts float valve.Be fixed with admission line 2, gas outlet 6 among the figure on tank body 1, inlet 10 and leakage fluid dram 8 are distributed with qi-emitting hole 9 on the admission line 2 in tank body 1, are used for the gas in entering jar is distributed under the liquid level in the tank body uniformly; Be fixed with Liqiud-gas mixing device 7 in tank body 1, in this embodiment, Liqiud-gas mixing device 7 has adopted float valve 11.The course of work of the present invention is: liquid adds in the tank body 1 by inlet 10, liquid level 4 is controlled on the Liqiud-gas mixing device 7, gas is by behind the admission line 2, enter in the liquid by the perforation qi-emitting hole 9 that is fixed under the liquid, because specific gravity of gas is light, in liquid, constantly rise, in uphill process, constantly collide and contact, adsorb, washings such as adhesion with fluid molecule; Finish first step washing process; Gas and is fixed in subsurface Liqiud-gas mixing device 7 and further mixes in the time will reaching the liquid level face, and gas is washed once more, finishes washing process for the second time; The gas that purifies is again by mist eliminator 56 discharges from the gas outlet; In gas purification process, a large amount of gas in the liquid that can be trapped with impurity, finish the purpose of changing liquid by the valve of control liquid outlet, to guarantee the cleaning in the tank body.
Fig. 2 is the structural representation that Liqiud-gas mixing device adopts bell jar.Its course of work is identical with Fig. 1, does not do too much explanation here.
Certainly also can adopt the Liqiud-gas mixing device of other plank frame such as screen cloth, but the inventor thinks, adopt Fig. 1 and the given method gas-liquid mixed better effects if of Fig. 2.
