Description

Remote Monitoring, Early Warning and Fault Diagnosis System for Anode Protection Equipment Based on Internet of Things

technical field

The utility model relates to the technical field of the Internet of Things and the field of anode protection equipment in the sulfuric acid industry, in particular to a remote monitoring, early warning and fault diagnosis system for anode protection equipment based on the Internet of Things technology, and the utility model also relates to the anode protection equipment based on the Internet of Things technology Remote monitoring, early warning and fault diagnosis methods.

Background technique

Anode protection equipment is the key equipment in the dry suction section of the sulfuric acid industry. It has the characteristics of corrosion resistance, energy saving, and environmental protection. Sold to Iran, North Korea, Zambia and other countries. However, anode protection equipment is a new type of corrosion-resistant equipment that combines anodic protection technology with stainless steel concentrated sulfuric acid equipment, and has extremely high requirements for maintenance and management. Changes in production process parameters, changes in anode protection parameters, and the level of the liquid level of the anode protection acid divider (one of the anode protection equipment) will all affect the corrosion resistance of the equipment. With the widespread application of anode protection equipment, some problems in its maintenance and management have become increasingly prominent, mainly as follows: first, there are "blind spots" in on-site equipment maintenance and management; Third, it is difficult to analyze the cause of equipment failure; fourth, it is difficult to maintain and manage export equipment, etc. These problems directly affect the performance of anode protection equipment. It can be seen that the key to achieving safe and high-quality operation of anode protection equipment is to improve the maintenance and management level of anode protection equipment. There are usually two methods: one is that sulfuric acid production enterprises are equipped with a professional equipment maintenance team, but due to the constraints of personnel and funds, many sulfuric acid production enterprises have "blind spots" in this regard; However, due to the constraints of timeliness and economy, it is also difficult to meet the needs of sulfuric acid production enterprises.

In order to strengthen the maintenance and management of anode protection equipment, most sulfuric acid production enterprises currently use the method of connecting the potentiostat, that is, the anode protection parameter control device of the anode protection equipment, to the DCS control system of the enterprise to monitor the changes in the anode protection parameters of the anode protection equipment. Equipment maintenance personnel in sulfuric acid enterprises can centrally monitor the changes of anode protection parameters of the anode protection equipment in the enterprise through the DCS control system, realizing the centralized management of the anode protection equipment in the enterprise. However, the operating status of the anode protection equipment is not limited to the anode protection parameters, and the changes in the production process parameters and liquid level parameters greatly affect the operation status of the anode protection equipment. In addition, as a highly dangerous chemical, sulfuric acid is extremely corrosive and oxidizing, so that once anode protection equipment leaks, it will cause great harm to equipment, the environment and personnel. It can be seen that real-time monitoring of the corrosion status of anodic protection equipment is also particularly necessary. Obviously, the monitoring of anode protection equipment by DCS control system is limited to anode protection parameters, the monitoring parameters are too single, and there is no fault diagnosis function.
