industrial Wastewater Treatment systems
multi effect evaporator For chemical organic wastewater characteristics such as high salt concentration, based on the principle of evaporation concentration crystal. USES the multistage decompression evaporation crystallization concentrated organic wastewater, the concentrate of salt after the separation, recycle, via the collection of salt concentrate drying recycling or incineration, and after the evaporation of condensed water usually by the subsequent biochemical treatment process, can realize wastewater discharge standard.
Evaporator evaporation from small to large, divided into 1-30 tons per hour than four effect evaporator concentration up to 10~15%.Can according to the turnkey project completion.
The basic information
A effect evaporator Direct the condenser
The second effect evaporator Condensed water heater
Three effect evaporator A centrifugal pump
Four effect evaporator Field instruments
Display, control cabinet cooling water tank
Platform framework piping
Installation, debugging, engineering design, technical services
2, containing ammonium chloride wastewater multiple effect evaporator to relieve stress
The second effect evaporator crystallization device is introduced
Two heat pump evaporation process, takes into consideration the discharge temperature of concentrate, ensure concentrate not precipitate crystallization.
Concentrate feed after preheater first, and then into the evaporator, separated the preheat sections and evaporation, and all the evaporator pipe used for evaporation, the evaporation efficiency of the improved evaporator.Concentrate grade preheating make full use of the latent heat of low temperature steam improves the thermal efficiency.
The first of the condensed water heating chamber into the shell side of the second effect of the heating chamber, will flash off part of the steam, make full use of the sensible heat of high temperature condensed water, reduce the steam consumption.
The first effect evaporator using low heat, can increase the extraction coefficient of heat pump, a complete set of equipment of the steam consumption is 0.45 tons of steam/tons of water.
A effect evaporator Direct the condenser
An effective separation chamber The secondary steam piping
The second effect evaporator vacuum pump
Two effective separation chamber instrument distribution valve line platform
Heat pump material storage tank
Circulating pump crystallization cans
Condensing water centrifuge
The characteristics of
1, evaporation of water can reach 0.5 t/h ~ 100 t/h 
(2) when the normal operation of the system only USES electricity, evaporation of water consumption per ton of 15 kw. H to 100 kw. J h, its operating cost for multiple effect evaporation 1/8 ~ 1/2.
(3) is currently the most energy-efficient evaporator, mostly single effect evaporation, the heating temperature difference is small, short residence time, suitable for heat-sensitive materials.
(4) the structure is compact, cover an area of an area small.
(5) through the PLC control to realize automatic operation equipment, long-term continuous and stable operation.
2, steam compressor
Waste water evaporator for mechanical evaporator, its main characteristic is that the steam compressor.Steam compressor by mechanical compression, and improve the steam pressure and temperature.In accordance with the requirements of air volume and compression choose different types of compressors, steam steam compressor speed by frequency converter to adjust, compressor rotation speed can be adjusted according to actual demand compressor is equipped with temperature monitoring sensor and vibration sensor, ensure the normal operation for a long time.
