Description

A gas purification device and method

Field: The present invention relates to a gas purification device and method.

Background technology: Chinese patent discloses a gas purification device, its [application number] is 01217733.4, it mainly includes a housing, the lower part of the housing is provided with an air inlet, the housing is also provided with a support frame, a fluid ball layer, a sprayer And the dehydrator, the sprinkler is composed of a pipe and a sprinkler head; the sprinkler head is made up of at least two horn-shaped plates arranged in gaps, and the center of the bottom of the horn-shaped plates is provided with a through hole, and the outermost horn-shaped plate The central through hole at the bottom of the tank is sealed and connected to the pipeline; the technology disclosed in this patent is to purify the gas entering the shell through the spray water of the shower, because the gas cannot fully contact the spray water after entering the shell, so Affect the purification efficiency of gas.

In addition, the Chinese patent also discloses a gas purification device of another structure, and its [publication number] is 2366749. The technology disclosed in this patent is to be provided with a long cylindrical filter in the adsorption vessel, and the column end of the cylindrical filter is connected with the The outlet pipes are connected, and a strip-shaped ultraviolet generator is also arranged on one side inside the adsorption container. Its existing problem is that the cylindrical filter needs to be manually cleaned or replaced frequently; the second is that the purification efficiency is greatly affected by the cylindrical filter material, and the process is complicated.

The 3rd technology that the present invention compares is a kind of gas purifying device disclosed by Chinese patent equally, and its [publication number] is 2480046, and this device has a casing 1, and casing 1 is provided with inlet pipe 2 and exhaust pipe 3 and The sealing cover 6, the intake pipe extends into the shell, and extends below the liquid surface, the shell is equipped with a certain volume of liquid 4, the separator 7 between the liquid surface and the exhaust pipe is equipped with a filter 5, and the filter is made of sponge body or activated carbon. This technology uses a combination of separation and filtration to purify and filter the flue gas, but it still has the problem that it needs to manually replace the sponge body or activated carbon.

SUMMARY OF THE INVENTION: The purpose of this invention is to design a gas purification device with high purification rate and simple operation.

The purpose of the present invention is achieved in this way, design a kind of gas purification device and method, it comprises tank body, the inlet pipe that is connected on the tank body, gas outlet, liquid inlet and liquid outlet, it is characterized in that: Air distribution holes are distributed on the air intake pipe in the body, which are used to evenly distribute the gas entering the tank; a gas-liquid mixing device is fixed in the tank.

The gas-liquid mixing device is a floating valve fixed on the plate.

The gas-liquid mixing device is a bell jar.

The gas purification method is: add liquid through the liquid inlet, so that the liquid surface is controlled above the gas-liquid mixing device. After the gas passes through the inlet pipe, it enters the liquid through the perforated gas distribution pipe fixed under the liquid surface. Due to the light specific gravity of the gas, Rising continuously in the liquid, during the rising process, it continuously collides with liquid molecules, absorbs, adheres and washes; completes the first step of washing process; when the gas is about to reach the liquid surface, it is further mixed with the gas-liquid mixer fixed under the surface Mixing, so that the gas is washed again, and the second washing process is completed, and the purified gas is discharged from the gas outlet; during the gas purification process, the impurities in the gas will be trapped in the liquid, and the replacement is completed by controlling the valve of the liquid outlet The purpose of the liquid is to keep the tank clean.

Because the present invention divides gas purification into two processes, the liquid mist and attached impurities in the gas entering the tank can be fully contacted with the liquid, the impurities can be fully contacted with the liquid, and the impurities can be adsorbed and adhered to the liquid. To achieve the purpose of high purification rate, the liquid in the tank can be replaced regularly to ensure that the impurities deposited in the liquid are discharged from the outside of the tank in time.

The present invention will be further described below in conjunction with the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS: Figure 1 is a schematic structural view of Embodiment 1 of the present invention;

Fig. 2 is a schematic structural diagram of Embodiment 1 of the present invention.

Embodiment: Figure 1 is a schematic structural view of a gas-liquid mixing device using a float valve. In the figure, an air inlet pipe 2, an air outlet 6, a liquid inlet 10, and a liquid discharge port 8 are fixed on the tank body 1, and air distribution holes 9 are distributed on the air inlet pipe 2 in the tank body 1, and are used for distributing air into the tank body 1. The gas in the tank is uniformly distributed under the liquid surface in the tank body; a gas-liquid mixing device 7 is fixed in the tank body 1 , and in this embodiment, the gas-liquid mixing device 7 adopts a float valve 11 . The working process of the present invention is: the liquid is added into the tank body 1 through the liquid inlet 10, so that the liquid level 4 is controlled above the gas-liquid mixing device 7, and after the gas passes through the air inlet pipe 2, it passes through the perforated air holes fixed under the liquid 9 Entering the liquid, due to the light specific gravity of the gas, it continues to rise in the liquid, and during the rising process, it continuously collides with liquid molecules, absorbs, adheres, etc. to wash; complete the first step of washing process; when the gas is about to reach the liquid level, It is further mixed with the gas-liquid mixing device 7 fixed under the liquid surface, so that the gas is washed again to complete the second washing process; the purified gas is discharged from the gas outlet 6 through the mist catcher 5; during the gas purification process, a large amount of The impurities carried by the gas will be trapped in the liquid, and the purpose of replacing the liquid is completed by controlling the valve of the liquid outlet to ensure the cleanliness of the tank.

Fig. 2 is a schematic diagram of the structure of a gas-liquid mixing device using a bell jar. Its working process is the same as that in Fig. 1, so it will not be explained too much here.

Of course, other plate-type gas-liquid mixing devices such as screens can also be used, but the inventors believe that the gas-liquid mixing effect of the method shown in Figures 1 and 2 is better.
