Huzhou Xinghong is equipped with 3 waste disposal production lines, of which the 1# production line is a medical waste disposal production line, the main body of its disposal waste is medical waste, animal carcasses and so on.
The production process is rotary kiln incinerator, the tail flue gas treatment process is alkaline desulfurization and denitrification process, and the particulate matter treatment is bag filter. Its flue gas composition has SO2, NOx, particulate matter, HCL, H2S, dioxin, NH3 and other gases. Its flue gas discharge temperature is 100 degrees, which is characterized by high temperature, high humidity, high viscosity, high corrosiveness and low flow rate gas. Its CEMS system is installed at the 20-meter high platform at the exhaust port.
For a long time, due to this production process of high temperature, high humidity, high corrosive and strong viscous gas low flow rate and other characteristics, due to the flue gas flow rate for a long time in the 2 ~ 4 m / s.. Its CEMS system flowmeter originally used Pitot tube differential pressure meter and thermal flowmeter, are not normal operation, the production of enterprises have a certain impact.
After many researches, the company, in July 2018, installed UF200 ultrasonic flow meter of Nanjing Juri Automation Technology Co. Installed in the existing CEMS platform, alternative to other principles of flow meter operation.
After more than half a year of actual operation, the flue gas ultrasonic flow rate meter is in good operating condition, stable and reliable measurement data, and low maintenance. Sensor due to special anti-corrosion measures, the end face clean and good, no pollutants, no corrosion, to solve the CEMS system flow rate measurement of a major problem.
