Embodiment Construction

[0021] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and together with the embodiments of the present invention are used to explain the principle of the present invention and are not intended to limit the scope of the present invention.

[0022] See Figure 1 to Figure 3 , The circulating spray waste gas absorption tower includes a tower body 1, a baffle plate 2, a main spray device 3 and a secondary spray device 4.

[0023] An absorption chamber 11 is formed inside the tower body 1, and an air inlet 12, an air outlet 13, and a liquid discharge port 14 communicating with the absorption chamber 11 are opened on the tower body 1. The exhaust gas enters the absorption chamber 11 from the air inlet 12, and the The treatment liquid in the absorption chamber 11 is discharged from the gas outlet 13 after being treated, and the used t...

Abstract

The invention relates to a circulating spraying type waste gas absorption tower which comprises a tower body, a baffle, a main spraying device and a secondary spraying device. An absorption cavity is formed in the tower body, and a gas inlet, a gas outlet and a liquid outlet which are communicated with the absorption cavity are formed in the tower body; the baffle is arranged in the absorption cavity and forms a gap for waste gas circulation with the inner wall of the absorption cavity; the main spraying device comprises a main spraying head arranged at the top of the absorption cavity and a liquid inlet pipe communicated with the main spraying head, and treatment liquid in the liquid inlet pipe can be sprayed into the absorption cavity from the main spraying head; the secondary spraying device comprises a liquid pumping pipe, a liquid pump and a secondary spray head, the liquid inlet end of the liquid pumping pipe is arranged on the baffle, the liquid outlet end of the liquid pumping pipe is communicated with the secondary spray head, and the liquid pump is arranged on the liquid pumping pipe. Compared with the prior art, the circulating spraying type waste gas absorption tower has the advantages that the treatment liquid falling on the baffle plate is sprayed out again through the secondary spraying device, is in contact with waste gas and absorbs harmful substances in the waste gas, so that the utilization rate of the treatment liquid is increased, and the waste gas absorption effect is improved.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a circulating spray type waste gas absorption tower. Background technique [0002] The spray absorption tower is a device that purifies the air by spraying. The working principle of the spray tower is to use the contact between the gas and the spray liquid to transfer the pollutants in the gas that need to be treated to the liquid to achieve the purpose of purifying the exhaust gas. Purpose. Generally, the gas-liquid reverse absorption method is used for treatment. The spray liquid is sprayed downward from the top of the tower into a mist, and the waste gas to be treated is countercurrently flowed upward from the bottom of the tower to reach the purpose of contacting the gas-liquid. This treatment method can cool the waste gas, clean the waste gas and Remove particles. [0003] Existing spray towers generally directly pass the exhaust gas into the tower, the exhaust...
