[0002] High-quality coolers in the chemical industry are a type of heat exchange equipment used to cool fluids or gases. Water or air is typically used as the coolant to remove heat. These coolers include partition coolers, spray coolers, jacket coolers, and coil coolers. They are widely used as pure water, water-to-air, oil-to-water, and oil-to-air cooling devices for cooling and protecting large electrical equipment such as high-power silicon rectifiers, induction furnaces, and medium-frequency furnaces.

[0003] After searching, a waste gas condensing device for a chemical plant disclosed in Chinese patent publication No. CN106288846B can be used to inflate only the first condensing cylinder through a one-way valve, and the waste gas is collected through the first condensing cylinder and the second condensing cylinder, and then cooled by the first compressor, the second compressor and the condenser.
