Background

At present, many process flows of waste gas environmental protection treatment, sewage treatment and chemical industry need some condensing devices, and the condensing devices mainly function to condense moisture or other components in gas into liquid so as to collect or concentrate the liquid.

In the prior art, the treated medium is often condensed by an indirect refrigeration mode, a low-temperature secondary refrigerant (liquid) is prepared by a refrigeration unit, and then the secondary refrigerant is conveyed into a heat exchanger by a pump to realize heat exchange between the secondary refrigerant and the treated medium, and when the component to be condensed in the treated medium reaches a temperature below the dew point temperature of the component, the component is condensed into the liquid. The indirect refrigeration mode can cause certain energy loss through secondary heat exchange, meanwhile, the energy consumption of the pump can be increased, the energy efficiency of the whole system is low, and a more energy-saving technical scheme is urgently needed to improve the energy efficiency of the refrigeration system under the large background of the current energy-saving and emission-reducing and double-carbon policies.

In addition, some condensation processes can cause scaling problems, scaling can cause heat exchange efficiency attenuation and cause condensation efficiency reduction, and common condensation devices adopt more fixed tube plate type shell and tube heat exchangers or double-tube heat exchangers, and are often difficult to scale after scaling, and as the service time goes on, the devices gradually lose efficacy and need to be replaced by new devices, so that waste and operation cost increase are caused. Therefore, how to make the condensation device easier to remove the scale is also an urgent technical problem to be solved.
