Roots blowers made of stainless steel are not often seen in the industry, but they are often seen in the MVR evaporation treatment industry. Roots blowers made of stainless steel are mostly used for evaporation and crystallization, which is what we often call Roots steam compressors. The material of Roots steam compressors is often used in steam compressors, while ordinary Roots blowers are mostly made of cast iron. The two materials are mainly different in the following aspects:
1. Different hardness
The hardness of stainless steel Roots blowers is higher, and cast iron materials are easier to process.
2. Different prices
The price of stainless steel Roots blowers is higher. Needless to say, the products produced by expensive raw materials will naturally be expensive.
3. Thermal expansion coefficient
When stainless steel Roots blowers are used to transport steam, temperature is a factor that must be considered, because the thermal expansion coefficients of blowers of different materials are different. There is a big difference between the thermal expansion coefficients of cast iron blowers and stainless steel blowers.
The choice of material for Roots blower mainly needs to be determined according to the specific working conditions. The material of Roots blower has a relatively large impact on the performance in steam transportation, so the steam transportation needs to be customized.
As an important air transportation equipment in modern industry, stainless steel roots blower has significant advantages in environmental protection and corrosion resistance.
The Roots blower achieves high-efficiency air compression and transportation through dual rotors meshing with each other. Compared with ordinary Roots blowers, stainless steel Roots blowers, in addition to retaining the advantages of ordinary Roots blowers, also have characteristics such as corrosion resistance and high temperature resistance, and are suitable for harsh environments and special industrial needs.
In addition to wear resistance, the fast and efficient performance of stainless steel Roots blowers has also attracted much attention. Its fast and efficient characteristics are mainly reflected in the rapid transportation of media and efficient energy conversion per unit time. When transporting media, the stainless steel Roots blower can quickly suck in the media and pressurize it for transport, thereby improving work efficiency. Secondly, the stainless steel Roots blower can maintain a high energy efficiency conversion rate during the energy conversion process and reduce energy waste. Therefore, stainless steel Roots blowers have great advantages in speed and efficiency and have been widely used.
In addition, its structural design enables it to reduce energy consumption and maintenance costs more effectively, making it the preferred air conveying equipment in many industries.
1.Industrial waste water treatment (zero discharge in environmental protection)
● Industrial waste water's concentrate and water's recycling. For example, in plating, painting producing, medicine and pesticide, metal processing, paper, and crude oil producing industry's waste water treatment.
● Remove the organics and inorganic salt in the waste water.
it's a great problem how to reuse high saline waste water with low cost, but MVR evaporator is the best solving plan for such kind condition.
2.Chemical industry
Waste water treatment from hollow fiber elements production.
● Spices purification.
● Sodium chlorite and sodium persulfate and other chemical material's producing
● Seawater desalination.
● Organic additive's concentrate and crystallization.
● Extract liquid's refine
3.Medicine industry
Medicine industry in our country is very traditional, but it use many old evaporator, they are not only reduce the medicine's quality, but also waste many energy. Upgrading is in urgent and necessary for reducing the discharge of carbon dioxide.
● Western medicine's evaporation, concentration, crystallization and drying.
● Traditional Chinese medicine's concentration.
4.Food industry
● In food deep processing industry, it is used for dehydration by evaporation. Such as concentration of corn syrup, extraction of glucose or amino acids etc.
● Extraction and concentration of isopropyl alcohol from pectin.
● Aromatic substance extraction and enrichment.
● Food and fermentation spices distillation precipitate and solvent's refining.
5.Wine industry
● Wine industry is very traditional in our country, MVR evaporator can instead the old evaporation equipment.
6.Milk industry
● Milk industry’s features decide traditional evaporator can't satisfy this industry, for example, low temperature, high-level cleanness, high-level automatic etc. Under this trend, MVR evaporator has a great market in this industry.
7.Concentration in beverage industry
● Ketchup
● Peach pulp
● Apricot jam
● Carrot pulp
● Apple pulp
● Kiwi pulp
