Abstract: Disclosed is a device and method for alternately controlling the operation state of two treatment equipment, each of which alternately operates to treat process emissions from a semiconductor manufacturing process, with two pipelines conveying the emissions to each of the treatment equipment, and two electric heating units providing heat to each of the pipelines, wherein the control device has a human-machine interface controller, a programmable controller, and a signal transmission port, the programmable controller sequentially controlling each of the control valves and each of the electric heating units so as to cause the electric heating units to select ramping up or ramping down the power rate, respectively, to reduce the electric energy consumption of the electric heating units in a standby state, and to reduce the overall carbon emissions.

Abstract: An airbag hot wind heat-insulation device includes an airbag unit, a heat insulation unit, a hot air supply unit, a return air pipe and a control unit, wherein an airflow channel is formed inside the airbag unit, and the hot air supply unit communicates with the airflow channel, and the hot air supply unit sends hot air to the airflow channel, thereby heating and insulating the heated object configured with the airbag unit. The return air pipe connects the airbag unit and the hot air supply unit, and the return air pipe connects the end of the path along which the hot air flows along the airflow channel and the air inlet end of the hot air supply unit, and accordingly returns the hot air to the hot air supply unit to improve heating efficiency.

Abstract: A disaster prevention and warning system is used to monitor an electrical thermal insulation system for a pipeline. The electric thermal insulation system includes a plurality of heaters and a plurality of temperature controllers, each of which is electrically connected to first and second electrical connectors, respectively. The disaster prevention and warning system includes pluralities of first and second thermocouples and a human-machine interface controller. The human-machine interface controller includes a programmable controller and a warning device, and the programmable controller is electrically connected to the warning device. The programmable controller judges if the temperature of the heater is higher than the first warning temperature value or if the temperature of the first electrical connector is higher than the second warning temperature value.
