Waste gas treatment process for threonine production

Abstract

The invention relates to a waste gas treatment process for threonine production. The waste gas treatment process comprises the following steps of: a, waste gas distribution; b, dedusting; c, energy collection; d, buffer storage; e, aerial fog filtering; f, catalytic cracking; and g, tail gas emission. Gas outlets of high-energy electron beam devices are connected with a same discharge device, thedischarge device comprises a fan and a chimney, and the purified tail gas is discharged through the fan and the chimney. When the method is used for treating tail gas, VOCs waste gas is effectively purified, and the method has the advantages of good treatment effect, low operation cost, no secondary pollution, easy and convenient operation, and stable operation, and the lampblack and flue gas purification efficiency reaches 98% and the VOCs foul smell purification efficiency is 99% or above. Besides, the wind power generation device can reduce the impact force of waste gas while collecting energy, and damage of the waste gas to the buffer tank is reduced, therefore the service life of the whole set of system equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of threonine production, in particular to a waste gas treatment process for threonine production. Background technique [0002] Threonine is an essential amino acid. Threonine is mainly used in medicine, chemical reagents, food fortifiers, feed additives, etc. During the production of threonine, a large amount of waste gas will be generated, and the main components of the waste gas are volatile organic compounds (VOCs). If not treated, it will have a great impact on the surrounding environment. The traditional natural gas incineration method to treat industrial waste gas consumes a large amount of natural gas and oxygen, and emits harmful gases such as carbon monoxide and carbon dioxide. In addition, in the process of waste gas treatment, it is necessary to buffer the waste gas with a buffer tank to reduce the wind speed. The waste gas has a strong impact force before buffering, and the direct buffering wil...

Problems solved by technology

During the production process of threonine, a large amount of waste gas will be generated, and the main components of the waste gas are volatile organic compounds (VOCs). If it is not treated, it will have a great impact on the surrounding environment

The traditional natural gas incineration method to treat industrial waste gas consumes a large amount of natural gas and oxygen, and emits harmful gases such as carbon monoxide and carbon dioxide.

In addition, in the process of waste gas treatment, it is necessary to buffer the waste gas with a buffer tank to reduce the wind speed. The waste gas has a strong impact force before buffering, and the direct buffering will not only waste the kinetic energy contained in the waste gas, but also Damage to the buffer tank to a certain extent, thus reducing the service life of the entire system equipment
