Description

Technical Field

[0001] This utility model specifically relates to an antifreeze device based on CEMS exhaust emissions. Background Technology

[0002] CEMS, or Continuous Emission Monitoring System, is an automated system used to monitor pollutant emissions in industrial waste gas in real time. It is widely used in high-pollution industries such as power, chemical, steel, and cement to ensure that enterprises comply with environmental regulations and reduce their environmental impact. When conducting CEMS exhaust gas emission testing, antifreeze measures are necessary to reduce the impact of icing. Traditional heating and antifreeze devices mostly use temperature controllers and electric heat tracing to control the temperature. During heating, based on the temperature feedback from the temperature controller, the AC contactor continuously controls the power supply to switch on and off, so that the electric heat tracing heats the emission pipe.

[0003] However, the above heating methods are prone to damage due to frequent opening and closing of hardware such as AC contactors. At the same time, the temperature of the antifreeze part is not easy to stabilize, and the temperature controller does not track the temperature in a timely manner. Therefore, it is not possible to prevent and keep the exhaust gas emissions from freezing with minimal losses. To address this, we propose an antifreeze device for exhaust gas emissions based on CEMS. Utility Model Content

[0004] The purpose of this invention is to provide an antifreeze device based on CEMS exhaust emissions to solve the problems mentioned in the background art.

A power control module is connected to one side of the temperature control module.

[0009] Preferably, a PID controller is provided inside the temperature control module, and a power regulation component is connected to the PID controller via a wire below it. A touch screen electrically connected to the PID controller is provided on the front surface of the temperature control module.
