Deodorizing device and deodorizing technology for feed processing

Abstract

The invention relates to a deodorizing device for feed processing. The device comprises an inlet gas tank, an absorption tower, a UV reaction tank and an emptying tower. The inlet air tank comprises an upper bag dust collector and a lower deposition funnel, the absorption tower comprises a washing solution tank, a multistage gas washing layer and a booster pump, and the UV reaction tank comprisesa first filtering chamber, a UV reaction pot and a second filtering chamber. Inlet gas is dedusted trough the dust collector to avoid dusts in waste gas from blocking the subsequent absorption tower and UV reactors; a multistage filler and a multistage spraying mechanism are adopted, so the contact area of a spraying solution and waste gas to be treated is obviously increased, the absorption efficiency and the absorption effect are improved, and the odor is effectively removed; a pH feedback regulating system improves the efficiency in the absorption process, realizes the rapid and efficient automatic regulation, and further improves the whole production efficiency; and the UV reactors are adopted to treat the absorbed waste gas, so thorough decomposition of harmful substances is achieved,and the product quality is improved.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to a deodorizing device and process for feed processing. Background technique [0002] During the production process of the feed industry, a large amount of odorous gas will be produced, and it has a pungent odor, which will affect the working environment and the health of on-site workers. According to environmental protection requirements, the waste gas needs to be deodorized and purified. The current odor treatment process is only a single acid and alkali solution absorption or direct high-temperature oxidation treatment, the treatment effect is poor, there is still a large amount of residual toxic and harmful exhaust gas in the emptying port, and the pungent odor is difficult to remove, the gas after emptying It will still be enriched near the factory area and cannot be dissipated, which has caused serious environmental hazards and injury to the factory staff. Therefore, there is ...
