Product Details

Product introduction

High cod sewage features:

High chemical oxygen demand (chemical oxygen demand-cod) is an industrial sewage containing high concentration of biodeless organic substances. This type of sewage, if not directly treated, can cause critical pollution to the water areas, which affect the aquatic ecosystem and human health. Its features include:

1. High cod content: filled with high concentration of organic pollution, resulted in water soluble oxygen quickly, meaning the survival of aquatic creatures.

2. Strong detox: can contain harmful chemicals, have harmful effect on bacteria, which affect the biochemical treatment effect of sewage.

3. Poor biochemical ability: traditional biological treatment methods are difficult to degrade organic substances completely and require the use of physical or chemical methods to assist with treatment.

4. High color, strange smell: contains colorants and compounds, affect the water's feeling quality.

 

High cod sewage MVR evaporator component:

This device is mainly made up of preheating element, evaporator body, liquid gas separator, steam compressor, and core parts such as condenser. The components work together to complete efficient evaporator for high COD sewage.

 

Technical principle of high COD waste water MVR Evaporator:

In the working process of the MVR evaporator high COD sewage, the first time sewage is heated to the boiling point by pre-stage heater. It is then taken to the body of the evaporator and boiled in it to create steam, while organic substances in the sewage 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.

 

MVR high COD sewage evaporator advantages:

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

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

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

4. strong application ability: can deal with high COD sewage with different components and concentration, with good adaptation.

5. considerable economic benefits: while saving energy, it can also collect soluble substances from waste water and increasing economic benefits.

 

High cod waste water MVR evaporator application areas:

This device is widely used in pharmaceutical, food processing, papermaking, printing and dyeing, chemical industry and other industries, particularly suitable for the treatment of high-concentration organic sewage with traditional biochemical methods.

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.
