The MVR mechanical compression evaporator equipment is equipped with CIP cleaning pipes, which can be cleaned in situ. The entire equipment is easy to operate and has no dead ends.

The maintenance method of the three-effect wastewater evaporator is as follows: 1. Change the secondary smooth oil within 1 month during the initial operation, and then change the smooth oil once within 3-4 months. 2. After opening the low head, unscrew the bolt at the bottom of the U-groove of the rotor, and inspect the scraper and replace the scraper every four months. 3. Open the bottom bearing every two months, check the bottom bearing wear condition, and replace the bottom bearing if necessary. 4. According to the nature of the material, the inner cylinder should be soaked and washed regularly with warm water or solvent. 5. Add sealing fluid to the mechanical seal cavity once a month, and the sealing fluid is 20 # mechanical oil.

The principle of the sodium nitrate treatment process is: evaporative concentration by three-effect evaporation → flash crystallization of concentrated liquid by vacuum crystallizer → centrifugal separation of solid-liquid mixture by centrifugation → drying of solid materials by continuous dryer → product repackaging

This is a zero-emission solution for industrial waste liquids in various industries such as electroplating industry, coating production industry, medicine and pesticide industry, metal processing industry, paper industry and crude oil production industry. It is through membrane technology, biochemical, oxidation, MVR The comprehensive utilization of technologies such as evaporators will recycle useful substances in wastewater, and distillate water can be directly reused or discharged up to standards, reducing the cost of waste liquid treatment.

The multi-effect evaporator evaporation operation is a process of separating the volatile solvent and the non-volatile solute in the solution. Since the evaporation rate of the solvent depends on the heat transfer rate, the evaporation operation is a heat transfer process, and the evaporation equipment is a heat transfer equipment. The following is an analysis of the three major characteristics of the evaporation operation. 1. The energy recovery evaporation process is a solvent vaporization process. Because the latent heat of solvent vaporization is large, the evaporation process is a large energy-consuming unit operation. Therefore, energy saving is an important issue that should be considered in evaporation operations. 2. Materials and process characteristics During the concentration process of materials, solutes or impurities are often deposited on the heating surface and precipitate crystals to form a scale layer, which affects heat transfer; some solutes are heat-sensitive, and they are prone to deterioration at high temperatures if they are left for too long; Has a larger corrosive or higher viscosity and so on. 3. The boiling point of the solution rises. Because the solution contains nonvolatile solutes, the vapor pressure of the solution is lower than that of the pure solvent at the same temperature. The higher the concentration, the more pronounced this effect is.

Power consumption of MVR evaporator: MVR evaporator almost does not use steam, but the power consumption is much larger than ordinary multi-effect evaporator. In other words, the main energy used by MVR is electricity. The power consumption of the main motor of the MVR (steam mechanical compression fan) depends on the heat exchange area and evaporation temperature of the evaporator and the characteristics of the material itself.

The central circulation tube evaporator is only suitable for equipment with small evaporation capacity and single-effect operation.

The use of a three-effect evaporator can greatly reduce the consumption of steam and reduce the burden on the product when it is condensed. It can not only provide work efficiency, but also reduce cooling water consumption. Therefore, the three-effect evaporator is a relatively energy-efficient evaporator.

CIP cleaning in place (clean in place) is a cleaning method that does not require manual operation, including the equipment to be cleaned, pipes, and CIP cleaning machines. The CIP cleaning machine has two types of automatic control and manual monitoring. It can clean the dirt by using the controlled flow of the cleaning fluid to clean the equipment without disassembling or moving the equipment pipeline.
