A waste gas washing device

Abstract

The invention belongs to the technical field of waste gas treatment, especially a water washing device for waste gas. In view of the fact that the traditional water washing device is relatively simple and the ventilation is fast, the bubble volume of the gas in the water is relatively large, and the contact rate with water is low, resulting in For the general problem of water washing effect, the following scheme is now proposed, including a water washing box and an air washing pipe. An air distribution mechanism is installed on the end of the air washing pipe close to the water washing box, and a fixed frequency sealing mechanism is installed on the top of the water washing box. A conical chassis is welded on the peripheral outer wall of one end close to the port of the gas washing pipe, and a first curved cover plate is welded on the circumferential inner wall of the water washing tank close to the conical chassis. The invention can lead the gas evenly to the equidistant wave-shaped air guide grooves under the action of the auxiliary bump and the air distribution pipe, and effectively reduce the size of the gas bubbles in the water under the further subdivision of the air outlet pipe , increase the contact rate of gas and water, and improve the washing effect.

Description

technical field [0001] The invention relates to the technical field of exhaust gas treatment, in particular to an exhaust gas water washing device. Background technique [0002] Exhaust gas refers to the poisonous and harmful gas emitted by human beings in the process of production and life. Especially in chemical plants, steel plants, pharmaceutical plants, coking plants and oil refineries, etc., the exhaust gas emitted is very smelly, which seriously pollutes the environment and affects human health. Water washing is an effective method commonly used to remove particulate impurities and dust in exhaust pores. It can recycle materials in the gas, and can wash industrial waste gas to achieve harmless and pollution-free discharge. It is especially commonly used for dust removal and desulfurization of boiler flue gas. Therefore, gas washing has a wide range of applications in various fields. [0003] However, most of the traditional water washing devices are relatively simpl...

Problems solved by technology

[0003] However, most of the traditional water washing devices are relatively simple in structure, and the gas bubbles in the water are often relatively large in volume, and the contact rate with water is low, and the larger the gas bubbles, the larger the volume of the displaced water, and the faster the rising speed, resulting in washing time.
