Advantages and disadvantages of sewage evaporators in wastewater treatment equipment

1. The steam compressor immediately sends thermal energy to the main heat exchanger. The water in the main heat exchanger is heated and evaporated, but the sewage cannot circulate quickly in the system. With the continuous evaporation of water, the concentration of sewage increases. Coupled with sustained high temperature, chlorite precipitates to form dirt, which easily adheres to the surface of the heat exchanger.

 

2. Once the main heat exchanger accumulates scale, it is difficult to remove the heat exchanger and maintenance is inconvenient. To solve the problem of more foam when cleaning sewage, the vacuum compressor will immediately send the heat energy  to the main heat exchanger with a large amount of defoaming additives. The water in the main heat exchanger will be heated and volatilized, but the sewage will be volatilized continuously with the water content, and the sewage concentration value will become higher and higher. The foam plastics that appear will accumulate with each other, and the foam plastics will rise to achieve a certain relative height. Add defoaming additives to eliminate the foam plastics.
