Coal Gas Desulfurization Equipment Detection and Automatic Control
Coal gas desulfurization is one of the most important parts of coal gas treatment and recovery, and plays an essential role in the control and treatment of coal gas pollution. The accurate detection of the coal gas desulfurization device is of great significance for controlling the desulfurization efficiency, ensuring the safe and efficient operation of the device, and ensuring the quality of the gas discharged. This article will analyze the detection of coal gas desulfurization equipment and automatic control in detail.
The detection and automatic control of coal gas desulfurization device mainly includes the detection of coal gas dust content, sulfur content, temperature and flue gas pressure and flow rate, as well as the detection of desulfurization devices operating parameters such as air supply, reaction temperature and absorption efficiency.
1. Detection of Coal Gas Dust Content: The dust content of coal gas mainly determines the operation mode of the dust removal device. Dust occupies the most in coal gas, so it is necessary to have the accurate dust content of coal gas collected in the dust collection device. Dust content detection equipment such as laser particle counter can be used to measure the dust content of coal gas. In addition, dust concentration meter is a relatively accurate dust content measurement method, which has good accuracy and can obtain the dust concentration of a certain gas sample in a certain period of time.
2. Detection of Sulfur Content: The concentration of sulfur compounds in coal gas is usually measured by gas chromatograph. The sulfur content of the original coal gas can be accurately detected by the device, and the control of its desulfurization efficiency can be achieved by understanding the sulfur content after desulfurization.
3. Detection of Temperature and Flue Gas Pressure and Flow Rate: The temperature measurement of flue gas can be carried out by temperature probes with different accuracy. The pressure and flow rate of flue gas can be measured by flow meter with pressure gauge, differential pressure detector and flow meter.
4. Detection of Desulfurization Devices Operating Parameters: The detection of desulfurization devices operating parameters mainly includes the detection of operating parameters such as air supply, reaction temperature and absorption efficiency. The operating parameters of the desulfurization device are mainly affected by the power supply and air supply, so the detection of these parameters should be done in a timely manner.
Automatic Control: The automatic control of coal gas desulfurization equipment mainly refers to the control of the operating parameters of desulfurization equipment, including the control of air supply, reaction temperature and absorption efficiency. The automatic control system can be used to monitor the operating parameters of the desulfurization equipment in real time, analyze the feedback data and make the necessary adjustments to ensure the safe, efficient and stable operation of the device.
In conclusion, the detection and automatic control of coal gas desulfurization equipment plays a very important role in controlling and treating coal gas pollution. The accurate detection of the coal gas desulfurization device is necessary for controlling the desulfurization efficiency, ensuring the safe and efficient operation of the device, and ensuring the quality of the gas discharged. The automatic control system can be used to monitor the operating parameters of the desulfurization equipment in real time, analyze the feedback data and make the necessary adjustments to ensure the safe, efficient and stable operation of the device.
