Product Introduction
Methane Online Monitoring Terminal - Safety Monitoring in Coke Oven Gas Purification Area - Product Overview
The methane online monitoring terminal is a gas detection terminal device used for safety monitoring in the coke oven gas purification area. Search keywords: methane online monitoring terminal, safety monitoring in coke oven gas purification area, methane alarm. This terminal can continuously detect the methane concentration in the purification area. When the concentration exceeds the set value, it emits sound and light alarms and outputs linkage signals to control ventilation and shut-off equipment. In the safety monitoring of the coke oven gas purification area, the methane online monitoring terminal can reflect in real time the methane changes in the desulfurization, deamination, and benzene recovery areas, ensuring the safety of operators.
Methane Online Monitoring Terminal - Safety Monitoring in Coke Oven Gas Purification Area - Working Principle
The methane online monitoring terminal uses a catalytic combustion sensor or infrared sensor to output electrical signals by detecting methane concentration, and after processing by a microprocessor, determines whether to alarm. In the safety monitoring of the coke oven gas purification area, the methane online monitoring terminal supports RS485, 4-20mA, and Modbus outputs and can be connected to PLC, DCS, and gas alarm control systems. The terminal has an explosion-proof housing and a high protection rating, making it suitable for the high-temperature, high-dust, and corrosive environments of coking plants.
Methane Online Monitoring Terminal - Safety Monitoring in Coke Oven Gas Purification Area - Application Scenarios
The methane online monitoring terminal is widely used in the desulfurization area, deamination area, benzene recovery area, and blower room of coking plants. In the safety monitoring of the coke oven gas purification area, the methane online monitoring terminal can be installed near purification towers, pipeline valves, and personnel inspection passages. The terminal can be linked with exhaust fans, shut-off valves, and fire protection systems to achieve automatic handling. For large coking plants, the methane online monitoring terminal can also form a multi-point monitoring network and upload data uniformly to the control room.
Methane Online Monitoring Terminal - Safety Monitoring in Coke Oven Gas Purification Area - Technical Advantages
The methane online monitoring terminal has advantages such as convenient installation, continuous monitoring, and flexible linkage. In the safety monitoring of the coke oven gas purification area, the methane online monitoring terminal uses industrial-grade sensors and explosion-proof design, making it suitable for long-term operation. The terminal supports sound and light alarms, fault self-diagnosis, and remote output, and is easy to maintain. When selecting a methane online monitoring terminal, attention should be paid to the detection range, accuracy, response time, explosion-proof rating, and output method to ensure reliable and effective safety monitoring in the coke oven gas purification area.
