Intelligent control waste acid cracking furnace and waste acid cracking system

Abstract

The invention discloses an intelligent control waste acid cracking furnace and a waste acid cracking system. The intelligent control waste acid cracking furnace comprises a sulfuric acid pump body, a sulfuric acid inlet pipe is fixedly arranged on the left side of the sulfuric acid pump body, a cracking furnace is arranged on the right side of the sulfuric acid inlet pipe, a furnace cavity is formed in the cracking furnace, the right surface wall of the furnace cavity communicates with the right surface of the cracking furnace through a rack cavity, and the right surface of the sulfuric acid inlet pipe is fixedly connected with the furnace cavity through a one-way valve. The temperature change can be flexibly controlled according to the volume of waste acid, the cracking process is safe and efficient, the cracking temperature at the bottom can be transmitted to the upper layer, the purpose of cyclic heating is achieved, through double-layer protection on a tank body, the safety of the cracking process is achieved, an emergency anti-leakage scheme can be started after leakage of the tank body occurs, the gas in the tank is completely discharged into the leaked gas storage tank, so that the danger is reduced to the minimum, and all work is stopped to wait for maintenance of maintenance personnel, so that the safety of the cracking process is ensured.

Description

technical field [0001] The invention relates to the technical field of waste acid cracking, in particular to an intelligently controlled waste acid cracking furnace and a waste acid cracking system. Background technique [0002] Some enterprises use sulfuric acid as an auxiliary raw material for the production of waste sulfuric acid that cannot be disposed of. Some use acid-base comprehensive treatment, and some use the method of hoarding and storage, which wastes resources and pollutes the environment. The waste acid cracking furnace is used to process waste sulfuric acid, and sulfur dioxide gas is generated by cracking to regenerate sulfuric acid, which not only saves resources but also protects the environment. Adopting a new type of waste acid cracking furnace and a new cracking combustion technology, the advantages are high degree of automation, high cracking efficiency, and high production safety performance.

AI Technical Summary

Problems solved by technology

[0003] Traditional waste acid pyrolysis has the disadvantage that it cannot be heated on demand. Often different amounts of liquids are pyrolyzed at the same temperature, which will lead to insufficient pyrolysis or too fast pyrolysis, which will cause the air pressure in the tank to increase rapidly, resulting in some dangerous accident happened

[0004] The traditional waste acid pyrolysis furnace has defects such as leakage of liquid sulfuric acid and overflow of gaseous sulfuric acid after long-term use, which can easily cause dangerous accidents such as flash explosions, especially the gaseous sulfur dioxide dispersed in the air, which will not only cause people to inhale danger, and a huge explosion will occur after contact with Mars, which will cause irreversible dangerous accidents
