Product Details

Product introduction

 

 

Efficient treatment of different types of solutions

- MVR evaporators 

 

MVR evaporators are used in the manufacturing industry and in various industries. The introduction of evaporation equipment into production helps to save resources and reduce costs: clean distilled water is returned to production, and less money is needed for waste treatment. MVR evaporators can be used for liquid treatment in plants producing inorganic salts, nitrogen fertilizers, paint and varnish industry, electroplating production, pharmaceuticals and confectionery factories. The technology can significantly reduce the amount of waste treatment.

 

What can MVR evaporators bring?

  • Provides evaporation of solutions with a wide range of capacities.
  • There is no waste heat steam discharge, and the energy saving effect is very significant.
  • Reduced energy costs compared to single-shell units.
  • Only a very small amount of raw steam is required.
  • Fully automatic operation, continuous operation.

High salt sewage features:

 

In the industrial production, the high salt sewage usually mentioned that the sewage water contains more soluble inorganic salt, such as sodium, potassium, calcium, magnesium plasma, as well as some heavy organic substances and metal ions. This sewage main features include:

1. high salt content: getting higher conductivity of water, affect water quality and can damage to ecoenvironment.

2. corrosion: the charged ions will expedite the corrosion of metal pipes and equipment, resulting in a loss of life.

3. high osmosis pressure: the water molecules need to pass the higher osmosis pressure when passing the semi-osmosis membrane, increasing the cost of processing and difficult.

4. degradable: heavy organic substances and metal ions are difficult to degrade, and can lead to long term environment problems.

 

 

High salt water discharge MVR evaporator component:

 

MVR high salt water evaporator is mainly composed of parts such as preheater, evaporator body, liquid gas separator, evaporator and condenser. These ingredients work together to complete the evaporator and concentrate of high salt content sewage.

 



MVR evaporator high salt water evaporator advantages:

 

1. High efficiency and energy saving: by the application of steam compression technology, significantly reduces reliability on external energy and reduces operating cost.

2. Environmental friendly: Do not add chemicals during processing to avoid secondary pollution.

3. Automatic operation: equipped with intelligent control system, it can achieve high automatic operation and reduce labor cost.

4. High response: can deal with high salt waste water with different ingredients and concentration, have good applications.

5. Economic effect: while saving energy, it also can collect soluble impurities from waste water and improve the economic effect.

 


High salt waste water MVR evaporator application areas:

 

MVR high salt water evaporator can be widely used in chemical, metallurgy, electric, petroleum, pharmaceutical and other industries. It provides a high-efficiency, economical and environmental salt water treatment program for all kinds of businesses.

 

 

Technical principle of

 

Technical principle of high salt water discharge MVR Evaporator: in working process of high salt water MVR evaporator, the softener is first heated in the pre-stressed heat to near the boiling point, and then applied to the body of the evaporator. Here the softener is heated until boiled to produce steam; then, water steam comes into the liquid separator to separate out pure vapor and concentrated liquid. Pure steam is inserted into the steam compressor, where temperature and pressure increase after pressing, and the evaporator continues to be used to deflate as a source of heat. While the concentrate is discharged from the system for subsequent treatment or recovery.

 

The production process of

MVR system evaporation process:

  

A. Feeding process:
The wastewater raw liquid is sent to the preheating system through the feed pump to exchange heat with distilled water for heating, and the heated wastewater raw liquid enters the separator. 

B. Evaporation process:
After entering the separator, the wastewater raw liquid is sent to the heater through the circulating pump, and heat is exchanged with the high-temperature secondary steam. The secondary steam condenses into water and enters the distilled water tank. The circulating liquid absorbs the heat of the steam, flashes in the separator, and separates the gas and liquid. The concentrated liquid is returned to the evaporator by the circulating pump to continue evaporation until the predetermined concentration is reached.

C. Discharging process:
When the predetermined evaporation concentration is reached, the system controls the discharging.
Non-condensable gases are automatically discharged through system control.

D. Drainage process:
The distilled water temporarily stored in the distilled water tank is transported to the preheating system through the distilled water pump, exchanges heat with the wastewater raw liquid for cooling, and then is sent out of the system.

Frequently Asked Questions

Q: MVR forced evaporator to run?

Cause: could be the corrosion of secondary steam pipes or steam compressors, pure water quality does not meet the standards, or at the point of equipment such as welding, flange, sealing, expansion, and so on.

Solution: ensure water quality into standards, regularly cleaning the system, maintain stable cooling water temperature, and provide a complete amount of cooling water.

 

Q: The steam reduction charged by MVR?

Cause: could be due to system clogging or dirt in the hot water catheter.

Solution: do online purification programs for cleaning dirt.

 

Q: The effect of steam valve charged by MVR?

Cause: The material is processed after thickening, crystally, resulting in clogging.

Solution: The Prevention includes regular filter of salt and spray as well, once stuck, use juice or vacuum treatment.

 

Q: MVR compulsory evaporator effect?

Expression: Produces regular and loud sound, vibrates the pipes.

Solution: constant current stability compressor when counter rate is soft and open the valve through the appropriate rate; counter rate need to close the compressor immediately for testing, pay attention to liquid temperature to avoid counter rate.

 

Q: cool MVR evaporator don't work properly?

Cause: could be due to too thick dust, or vacuum drop.
