A control system for hydrogen chloride synthesis furnace

Abstract

The invention relates to a hydrogen chloride synthetic furnace control system, which comprises a synthetic furnace, the synthetic furnace is divided into an upper segment, a middle segment and a lower segment, three segments are formed by a graphite cylindrical shell and a steel housing sleeved outside the cylindrical shell, three interlayer which are not conducted by each other are formed, the lower segment is conducted to the middle segment steel housing through a pipeline, a cooling water circulation channel is arranged on the lower segment and the middle segment, the middle segment and the upper segment, the lower segment of the synthetic furnace is a burning zone, a chlorine inlet pipe, a hydrogen inlet pipe and a nitrogen pipe are communicated to the bottom of the furnace port, a burning torch and a flame detector are respectively arranged at two sides of the furnace port, an igniting air pipe is connected to the air inlet of the burning torch in series, the hydrogen inlet is connected to the igniting hydrogen pipe in series, and the input end of the igniting hydrogen pipe is connected to the input end of the hydrogen inlet pipe and the input end of the nitrogen inlet pipe. The hydrogen chloride synthetic furnace control system has the advantages of simple structure, and safe and reliable operation.

Description

technical field [0001] The invention belongs to the field of hydrogen chloride preparation and relates to a control system for a hydrogen chloride synthesis furnace. Background technique [0002] The hydrogen chloride synthesis furnace is used to burn chlorine and hydrogen to produce hydrogen chloride gas. When chlorine gas and hydrogen are combusted, a large amount of heat of reaction is released, and the temperature in the central area of ​​the flame reaches above 2500°C, and the temperature of the generated hydrogen chloride gas is above 2000°C, that is, about 605Kcal of heat is released for every kilogram of gaseous hydrogen chloride synthesized, which is quite considerable for utilization. [0003] At present, the production of hydrogen chloride mainly uses manual control of production equipment. During the production process, it relies heavily on the operator's operating experience and proficiency; every step of the operation in the production process relies entirely o...

Problems solved by technology

[0003] At present, the production of hydrogen chloride mainly uses manual control of production equipment. During the production process, it relies heavily on the operator's operating experience and proficiency; every step of the operation in the production process relies entirely on the operator's operating experience. Once the operation is wrong, it may cause an explosion accident. ;The labor intensity of the operators is high and the risk is high; the requirements for the operators are high and the number is large. Each skilled operator with many years of operating experience can only take care of one synthesis furnace, and is required to always pay attention to the color of the flame and be responsible for the personnel. High requirements and many occupants
