Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of chemical equipment, and particularly relates to an acid gas combustion furnace eternal lamp ignition control system, which is suitable for the ignition control of combustion furnaces containing acid gases such as hydrogen sulfide. BACKGROUND

[0002] In the current chemical production field, the existing acid gas combustion furnace eternal lamp ignition system has many problems to be solved. On the one hand, the gas and air ratio control is not accurate enough, and most of them rely on manual valve adjustment. This method is extremely prone to human error of the operator, which leads to an imbalance in the proportion of mixed gas, and thus affects the ignition effect, and even causes ignition failure. On the other hand, the existing system generally lacks flow monitoring function, and cannot accurately obtain the flow data of gas and air in real time, so that the operator cannot effectively control the system running state. Moreover, it lacks remote control function, and in some special or dangerous working conditions, the operator needs to operate the valve at close range, which has certain safety risks. At the same time, there is a lack of temperature monitoring in the ignition process, and the equipment may fail due to overheating, and even backfire may occur, which seriously threatens the production safety. For example, in some actual production scenes, due to the inaccuracy of manual valve adjustment, the concentration of mixed gas does not meet the ignition requirements, and the ignition fails many times, which affects the production progress. Or because the temperature is not monitored in time, the equipment is locally overheated and damaged, which increases the maintenance cost and safety hazard. Therefore, there is an urgent need for an intelligent ignition system with accurate flow control, convenient remote operation and comprehensive safety monitoring to meet the growing safety and efficiency needs of chemical production.

[0035] Example 2
