Description

Device for condensing, recycling and reusing tail gas

Technical Field

The utility model relates to a tail gas processing apparatus field, concretely relates to be used for tail gas condensation recycling apparatus.

Background

Chemical plants produce a large amount of waste gases in the production process, such as inorganic waste gases including ammonia, trimethylamine, hydrogen sulfide, sulfur dioxide, methylthio hydrogen, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide, hydrogen sulfide, and the like, and VOCs: benzene, toluene, xylene, acrylic acid, ethers, lipids, alcohols, ketones, styrene and other organic waste gases. Both organic waste gas and inorganic waste gas have a common point and emit strong chemical odor. Moreover, most of the chemical waste gas peculiar smells have great harm to human bodies, if the chemical waste gas peculiar smells are not treated properly, the chemical waste gas peculiar smells not only have great influence on the surrounding environment, but also cause great damage to the health of chemical plant staff and surrounding residents.

For low-concentration large-air-volume VOC (volatile organic compound) polluted waste gas, the traditional tail gas treatment process comprises a VOC concentration and heat storage combustion device process, and the low-concentration large-air-volume polluted air can be concentrated into small-air-volume high-concentration waste gas and then is subjected to thermal combustion treatment. For acid inorganic pollution waste gas with large air volume, alkali absorption tower type treatment is generally adopted, tail gas is discharged after alkali liquor neutralization to reach the standard, but waste salt can also be produced.

Although the above two processes perform harmless treatment on the waste gas, the treatment also generates new pollution, and only reduces the influence of the original waste gas. Therefore, the recycling process needs to be considered in the aspect of waste gas treatment, and only recycling is the original purpose of energy conservation and emission reduction and the future development direction.
