Product Details

Product introduction

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.

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.

Problem: MVR is required to deflate slow feeding or a small flow situation?
Reason: usually due to the filter is blocked.
Solution: inspection and purification of filters.

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.
Solution: add agent foaming agent, check detector and dehumidifying liquid, import steam valve adjustment, vacuum control.

Q: MVR is required to circulation irregular level of steam separator?
Cause of the high level: too many data feed, Crystal pump fault or export focus clogging.
Solution: reduce the amount of data input, check the pump, open the drainage pipe.
Cause of the low level: too small or leaking of the concentration tube.
Solution: increase the amount of data input, check the drainage pipe.
