Formaldehyde oxidation reactor

Abstract

The invention relates to a formaldehyde oxidation reactor, which comprises a reactor body, a filtering chamber is fixedly installed on the lower portion of the left side of the reactor body, an air inlet pipe is movably installed on the left side of the filtering chamber, and the reactor body, the filtering chamber and the air inlet pipe communicate with one another; a cutting mechanism and a crushing mechanism are sequentially and movably arranged in the reactor body from bottom to top, and an anti-blocking mechanism matched with the cutting mechanism is movably arranged at the position, close to the lower end, of the left side in the reactor body. By setting up the cutting mechanism, the existing way of air intake through a pipe is changed, the industrial waste gas is divided into a plurality of parts, and is in contact with a potassium permanganate solution from each part of the bottom, so that the industrial waste gas is in more sufficient contact with the potassium permanganate solution, the formaldehyde is favorably purified, and the formaldehyde purification efficiency is improved; by setting up the crushing mechanism to crush large bubbles, and the contact area between the gas and the potassium permanganate solution is increased.

Description

technical field [0001] The invention relates to the technical field of formaldehyde oxidation, in particular to a formaldehyde oxidation reactor. Background technique [0002] Formaldehyde is a naturally occurring organic compound, a colorless irritating gas that is irritating to human eyes and nose, and is listed as a "known human carcinogen". Formaldehyde is widely used and is a popular chemical product with simple production process and sufficient supply of raw materials. Some industrial waste gas contains formaldehyde and dust. If the industrial waste gas is directly discharged into the air, it will pollute the surrounding environment. [0003] Existing formaldehyde oxidation reactor passes waste gas containing formaldehyde into potassium permanganate solution to purify formaldehyde, but when purifying, generally the exhaust pipe is inserted into the bottom of potassium permanganate solution, and the waste gas containing formaldehyde When the exhaust gas is in contact ...

Problems solved by technology

Some industrial waste gas contains formaldehyde and dust. If the industrial waste gas is directly discharged into the air, it will pollute the surrounding environment.

[0003] Existing formaldehyde oxidation reactor passes waste gas containing formaldehyde into potassium permanganate solution to purify formaldehyde, but when purifying, generally the exhaust pipe is inserted into the bottom of potassium permanganate solution, and the waste gas containing formaldehyde When the exhaust gas is in contact with the potassium permanganate solution, some large bubbles will be generated, which makes the reaction between the formaldehyde and the potassium permanganate solution insufficient, so that the purification effect on the formaldehyde is not good enough
