The high-salt wastewater evaporator is a technologically advanced evaporator, and its current applications are very wide.
1. The situation of evaporating salt. When purchasing a high-salt wastewater evaporator, you need to understand its salt production. Generally, it has two methods of producing salt, one is a centrifuge producing salt, and the other is a salt producing device combined with a crystal collecting tank to produce salt. The former produces salt with a very low moisture content, while the latter produces salt in the form of crystals. The form is separated out, so the external moisture is relatively low.
2. When we purchase this equipment, we need to choose the appropriate type. For the evaporation of salts, we give priority to the forced circulation evaporator. If the salt concentration is not too high, you can also choose a combination of a front falling film evaporator and a forced circulation evaporator.
3. During the evaporation process, there is the problem of COD removal rate. Since the COD in wastewater is mainly determined by the content of organic matter in it, the organic matter contained in the wastewater may be low boiling point or high boiling point. If it is low boiling point organic matter, then it needs to be during the evaporation process, as the condensed water enters the cooling and heating system, the COD in the condensed water cannot be reduced.
When purchasing a high-salt wastewater evaporator, you need to pay attention to the above contents and focus on the removal of COD during the evaporation process. For organic matter with a high boiling point, when they evaporate it can enter the waste liquid system, so the content in the condensed water will be reduced.
