Gas-liquid mixing device and method

Abstract

The invention relates to a gas-liquid mixing device and a method. The gas-liquid mixing device comprises a shell (1), an air inlet box (3) connected with the top of the shell (1), an air outlet box (4) connected with the bottom of the shell, a water tank (2) connected at the bottom of the air outlet box, and a pump (5) which is arranged outside the water tank (2) and connected with the bottom of the water tank (2) through a pipeline, wherein the pump (5) is also connected with a water inlet in the top of the shell through a pipeline, fan blades are arranged in the shell along the axis of the shell, and a motor is arranged outside the air inlet box and drives the fan blades to rotate through a transmission device. In the implementation of the gas-liquid mixing device provided by the invention, by utilizing atomized liquid for adhering impurities in waste gas, the filtering effect is improved; on the other hand, as the surface area of the atomized liquid is increased, the interaction area with the gas is increased.

Description

technical field [0001] The invention relates to the field of gas treatment, more specifically, to a gas-liquid mixing device and method. Background technique [0002] With the acceleration of urban development and industrialization, cooking fumes from homes and restaurants have gradually become a serious source of air pollution. In addition, factories, incinerators, etc. will also produce a large amount of harmful substances during operation, which need to be filtered before being discharged into the atmosphere. . [0003] Existing household oil fume treatment devices mainly rely on the high-speed rotation of the fan to generate centrifugal action to purify the oil molecules in the exhaust gas. When a large amount of oil fume enters these oil fume treatment devices, it is easy to accumulate oil in the oil fume treatment device, resulting in a reduction in the purification effect , energy consumption increases, and the accumulated oil is difficult to clean.

Problems solved by technology

[0003] Existing household oil fume treatment devices mainly rely on the high-speed rotation of the fan to generate centrifugal action to purify the oil molecules in the exhaust gas. When a large amount of oil fume enters these oil fume treatment devices, it is easy to accumulate oil in the oil fume treatment device, resulting in a reduction in the purification effect , energy consumption increases, and the accumulated oil is difficult to clean

[0004] In addition, it is difficult to apply the oil fume treatment devices used in households to industrial waste gas treatment, which makes the versatility of these waste gas treatment devices not high

[0005] On the other hand, in the aquaculture industry, a certain amount of oxygen needs to be dissolved in water, and traditionally, the efficiency of directly pumping air into water is low. Dissolved enough oxygen in the process
