Customized multi mvr evaporator crystallization for chemical effluent treatment sodium chloride + sodium acetate
Multiple effect evaporator
multiple effect evaporator contains of single-effect, dual-effect and triple-effect evaporators, single-effect, dual-effect and triple-effect separators, preheater, condenser and hot pressure pump.
(A) Low evaporation consumption, 1Kg steam can evaporate 3.5Kg water.
(B) Low evaporation temperature. Part of twice steam can be inhaled into single-effect heater through spray type hot pressure pump. The high quality evaporation can be fully used and the evaporation temperature is low.
(C) Large concentration ratio with downward film type evaporation, which can make material liquid with viscosity be so easy to flow and evaporate, Hard to agglomerate with short concentration time. The concentration ratio can reach 1:5.
(D) The equipment can realize automatic production, intellectual system.
What is the MEE(Multi-effect Evaporation) System?
The multi-effect evaporator system is a system in which multiple single-effect evaporators are connected in series to achieve continuous evaporation. Since evaporation is a process that consumes a large amount of steam to generate secondary steam, in order to make full use of the waste heat of steam, generally the previous secondary steam is introduced into the next effect as a heat source. This maximizes energy utilization efficiency while ensuring evaporation.
The selection of the number of stages of the multi-effect evaporator depends on various factors such as the specific material properties, the concentration of the incoming and outgoing materials, the temperature, and the energy consumption cost. Generally speaking, more stages will result in lower steam consumption. We are also committed to providing multi-effect evaporators and solutions suitable for various materials.
Where is it used, the application of Multi-effect Evaporation System?
Food Industry, Waste water treatment, Concentration and Crystallization.
What is the component part of this MEE Evaporator?
Heat Exchanger, recirculation pump, separator, condenser, transfer pump, condensate pump, vacuum pump, operation platform, control system.
Variants
Increase in the number of stages to reduce steam consumption.
With or without salt separation.
Different preheating concepts.
Vapour condensation of the vapour of the final stage in mixing or surface condensers.
Entry of the solution to be evaporated into the first stage (parallel flow) or into the last stage (counter flow). Accordingly, the concentrate is discharged cold (parallel flow) or hot (counter flow) from the plant.
