Clean production tail gas absorption system

Abstract

The invention provides a clean production tail gas absorption system. The clean production tail gas absorption system comprises a safety bottle, a solvent absorption tank, a multistage absorption tank, a cold trap, a buffer tank and a connecting pipeline, the safety bottle is a safety container used for preventing suck-back and stabilizing pressure. The solvent absorption tank is a container for dissolving tail gas in a solvent; the multistage absorption tank is a container for further absorbing the tail gas through a multistage absorption layer; the cold trap is used for quickly condensing substances in the tail gas under cryogenic conditions and preventing backflow; the buffer tank is a container used for stabilizing buffer pressure, the tail gas absorption system can achieve the production tail gas absorption and various absorption effects of dangerous chemicals and toxic and harmful compounds, absorption substances are convenient to replace under the saturated blockage condition, meanwhile, it is guaranteed that the absorption process and the replacement process are integrated, leakage pollution is avoided, and energy and cost are saved.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a production tail gas absorption system suitable for dangerous, toxic or special substances. Background technique [0002] In the process of clean production tail gas generation, there are special chemicals such as explosion, spontaneous combustion, poisoning, corrosion, etc., which must be in a well-closed environment to avoid the occurrence of hazards. Most of these special substances will face relatively high risk safety issues during the production tail gas emission process. During the operation of tail gas emission, leakage is very easy to occur, and the corresponding operation and equipment requirements are relatively strict, the operation is complicated, the time period is long, and it is time-consuming and labor-intensive. On the other hand, clean production has extremely strict requirements on air flow, and trace gas reflux is not allowed. When the system pressure is ...

AI Technical Summary

Problems solved by technology

[0003] The exhaust gas absorption process of such dangerous, toxic or special substances is generally a complicated operation process. Once the absorption is insufficient or the absorption material is saturated or blocked, it must face the safety risk of leakage, and the process of replacing the saturated and blocked absorption Substances are also very dangerous

This will cause a waste of resources, greatly reduce the efficiency, and the security of the operation cannot be guaranteed.

The process of replacing the absorbing material is often to disassemble the absorbing equipment for replacement after the absorption is saturated. The operation is cumbersome and unnecessary leakage may occur.
