Waste gas treatment process for threonine production

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 wa
