Product Details

Product introduction

Heavy metal exhaust water features: Heavy metal exhaust water mention industrial sewage containing harmful metal ions such as copper, lead, zinc, cadmium. This type of sewage if not directly treated, it will be a great risk to human health and environment. Its features include:


1. strong detox: heavy metal ions provide high detox to the human body and ecoenvironment.


2. difficult to biodegradable: Heavy metals are not easy to be biodegraded, easily stored in the food chain.


3. long residue: long lasting of heavy metal in the environment, broad impact.


4. difficult treatment: traditional chemical chroma could not completely remove heavy metal ions from sewage.

 

MVR evaporator introduction for heavy metal waste water:

MVR evaporator for heavy metal waste water is a high efficiency evaporator designed for heavy metal industrial sewage, using mechanical bubble recompression (MVR) technology, to achieve the concentration and filtration of waste water.

 

MVR evaporator component for heavy metal waste water:

This device is mainly made up of preheating element, evaporator body, liquid gas separator, steam compressor, and core parts such as condenser. They work together to complete an effective evaporator for heavy metal waste water.

 

MVR evaporator for heavy metal waste water advantages:

High efficiency and energy saving: vapor compression technology greatly reduces external energy needs and saves energy consumption.

Environmental Performance: no additional chemicals are required during processing, reduces the ability to secondary pollution.

High automation level: equipped with PLC control system to achieve high automation operation and reduce labor cost.

High application ability: can deal with heavy metal waste water with different ingredients and concentration, with good adaptation.

Considerable economic benefits: while saving energy, it also restores value metal resources from waste water and increasing economic benefits.

 

MVR evaporator application areas for heavy metal sewage:

This equipment is widely used in electroplate, electronic, metallurgy, chemical and other industries, particularly suitable for the treatment of industrial sewage with heavy metal ions.

 

Technical principle of

MVR evaporator technical principle for heavy metal sewage:

In the working process of MVR evaporator for heavy metal waste water, the first time sewage is heated to the boiling point by pre-heater. Then it is taken to the body of the evaporator and boiled in it to produce steam, while the heavy metal ions in the sewage water are concentrate. The results steam gets into liquid aerator, separation of pure vapor and concentrated liquid. Pure steam to the return of the evaporator as the heat source after strengthening by the vapor compressor, while the concentrate is further processed or recalled by the exhaust system.

Frequently Asked Questions

Q: MVR forced evaporator to run?

Cause: could be the corrosion of secondary steam pipes or air 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.

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