Fresh air oxygenation purification device for chemical workshop

Abstract

The invention relates to a fresh air oxygenation purification device for a chemical workshop. The fresh air oxygenation purification device comprises a shell. A fresh air device and a workshop air purification device are arranged in the shell. An air inlet pipe is arranged on the side wall of the bottom of the fresh air device. An air suction pipe is arranged at the top of the workshop air purification device. A return pipe connected with the air inlet pipe is arranged at the bottom of the workshop air purification device. The workshop air purification device is provided with a coarse filtration net, a purification nonwoven filtration net, a heating layer, a carbon monoxide absorption layer, a purification activated carbon adsorption layer and an alkali liquor pool sequentially from top tobottom. A molecular sieve absorption layer is arranged on the side upper portion of the alkali liquor pool and is connected with a suction fan. A temporary storage box is connected to an air outlet of the suction fan. According to the fresh air oxygenation purification device, poisonous gas in the workshop is purified and absorbed through the workshop air purification device and is then mixed with outdoor air, discharge of workshop air can be reduced effectively, and the purification effect is good. Compared with the prior art, the fresh air oxygenation purification device has substantive features and progress.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a fresh air oxygenation purification device for a chemical workshop. Background technique [0002] With the development of industry, my country's smog weather is becoming more and more serious and frequent, and people have paid more and more attention to air safety. For chemical workshops where harmful gases are concentrated, it is not only necessary to purify the incoming air, but also to clean the air in the workshop. The air discharge also needs to be purified, otherwise it will cause air pollution. The current indoor purification device only absorbs PM2.5 and inhalable particles, which cannot meet the needs of chemical workshops. Contents of the invention [0003] The object of the present invention is to provide a fresh air oxygenation purification device for a chemical workshop to address the deficiencies in the prior art. [0004] The present invention is achieved through...
