Circulating spray tower for organic waste gas treatment

Abstract

The invention discloses a circulating spray tower for organic waste gas treatment. The spray tower comprises a tower body, a spraying mechanism is installed on the right side of the bottom of the inner wall of the tower body, a clearing mechanism is installed at the bottom in the tower body, a detection mechanism is installed on the left side of the bottom of the inner wall of the tower body, a round opening is fixedly connected to the left side of the tower body, and a fixing mechanism is installed on the left side of the round opening. The invention discloses the circulating spray tower fororganic waste gas treatment. The problem that sodium hydroxide absorption liquid cannot be filtered when an existing spraying tower works and is recycled is solved through the removing mechanism; impurities are prevented from being mixed inside; it is guaranteed that the function is not reduced, and the expected effect is achieved; it is guaranteed that waste gas treatment is clean next time, theproblem that after sodium hydroxide absorption liquid is used multiple times, alkalinity of the sodium hydroxide absorption liquid is reduced, and detection cannot be conducted in time is solved through the detection mechanism, incomplete waste gas treatment is avoided, environmental pollution is avoided, human health is guaranteed, practicability is improved, and popularization is facilitated.

Description

technical field [0001] The invention relates to the technical field of spray towers, in particular to a circulating spray tower for organic waste gas treatment. Background technique [0002] In the spray tower, the liquid enters from the top of the tower, and is sprayed into mist or raindrops through the nozzle, and the gas enters from the lower part of the tower, and is in close contact with the mist or raindrops for mass transfer. So that the soluble components in the gas are absorbed, the existing spray tower cannot be filtered when the sodium hydroxide absorption liquid is recycled during work, resulting in impurities mixed in the interior, which reduces its function and fails to achieve the expected effect, affecting the next time waste gas treatment, and the alkalinity reduction of the sodium hydroxide absorption solution cannot be detected in time after repeated use, resulting in unclean waste gas treatment. After being discharged from the tower, it still pollutes the...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a kind of circulating spray tower for organic waste gas treatment, to solve the problem that the existing spray tower proposed in the above background technology cannot filter when the sodium hydroxide absorption liquid is recycled during work, resulting in internal mixing. There are impurities, which reduce the function and fail to achieve the expected effect, which will affect the next waste gas treatment, and after the sodium hydroxide absorption liquid is used many times, the alkalinity will be reduced and cannot be detected in time, resulting in the waste gas treatment being unclean and discharged from the tower. After that, it will still pollute the environment, cause harm to the human body, and have problems with low practicability.
