Intelligent acid discharge device

Abstract

The invention relates to an intelligent acid discharge device. The device includes an absorption tower, the absorption tower is connected to a buffer, a first front stop valve, a regulating valve anda first rear stop valve are connected in series between the absorption tower and the buffer, the branch formed by series connection of the first front stop valve, the regulating valve and the first rear stop valve is in parallel connection with a first by-pass valve, the buffer is connected to an acid storage geosyncline, a second front stop valve, an acid discharge regulating valve and a second rear stop valve are connected in series between the buffer and the acid storage geosyncline, the branch formed by series connection of the second front stop valve, the acid discharge regulating valve and the second rear stop valve is in parallel connection with a second by-pass valve, a liquid indicator is disposed at the top of the buffer, and the root regulating valve, the liquid indicator and the acid discharge regulating valve are in connection with a control system. The intelligent acid discharge device provided by the invention can achieve effective collection of the condensate acid of asulfur-to-acid production system and automatic, environment-friendly and safe discharge of the condensate acid into the acid storage geosynclines, and prevents the leakage of sulfur trioxide in the system into the air to pollute the environment and even cause human poisoning.

Description

technical field [0001] The invention relates to the field of chemical production and processing equipment, in particular to an intelligent acid discharge device. Background technique [0002] Smart manufacturing is the mainstream direction of national manufacturing development in the new era, and the chemical industry is no exception. Some companies even regard the construction of "smart factories" as a key project of the "13th Five-Year Plan". Sulfuric acid is the blood of the chemical industry and an essential raw material for phosphate compound fertilizers, storage batteries and other industries. However, the sulfuric acid manufacturing industry is a relatively traditional industry. Compared with organic fine chemicals, its intelligence level is relatively low. With the continuous progress of sulfur acid production technology, HRS low-temperature heat recovery technology is widely used in sulfur acid production equipment. The sulfur trioxide from the economizer is mixed ...

However, the sulfuric acid manufacturing industry is a relatively traditional industry. Compared with organic fine chemicals, its intelligence level is relatively low.

With the continuous progress of sulfur acid production technology, HRS low-temperature heat recovery technology is widely used in sulfur acid production equipment. The sulfur trioxide from the economizer is mixed with steam and then enters the HRS tower. During thi
