High pressure roots type vacuum pump roots steam compressor air blower
Competitive Advantages of roots compressor for MVR
1,Introduction to MVR principle
The mechanical vapor recompression evaporator, referred to as MVR, is based on the principle of compressing the secondary vapor generated by the evaporator through a high-efficiency vapor compressor, converting electrical energy into heat, and increasing the pressure and temperature of the secondary vapor. The steam enters the evaporation chamber to heat the material to evaporate, so as to achieve the purpose of recycling the latent heat of vaporization of the secondary steam. By using relatively little energy, that is, the mechanical energy of the compressor impeller in the case of a compression heat pump, the energy is added to the process heating medium and enters a continuous cycle. In this case, no primary steam is needed as a heating medium.
Description
1,Uses: This compressor is suitable for the purification of organic working fluids, seawater desalination, vapor compression and transportation, concentration and crystallization in the chemical, pharmaceutical, metallurgical, food industries and the secondary vapor recompression process of the MVR system for industrial waste liquid treatment.
2,Brief introduction of compressor structure:
The compressor consists of a main and driven rotor group, a shell, a mechanical seal, a bearing, a synchronous gear and a coupling:
(1)Compressor rotor group: The compressor rotor group is composed of the main shaft and the fan blade assembly. The main shaft is made of high-strength alloy steel; the fan blades are two blades, using advanced arc-involute profiles, and have passed the rotor dynamics calculations. The optimal structure can be obtained by analyzing the strength and rigidity of the rotor. The fan blades are integrally cast, and the material is different according to the composition of the materials processed by the process system. You can choose duplex stainless steel 2205, stainless steel 316L or ductile iron. After the fan blade is cast, it is processed by a machining center. The static and dynamic balance of the rotor group meets the design requirements, and the balance level is higher than G5.6
(2)Shell: The compressor shell is composed of working cavity, front and rear cover, fuel tank and front cover. According to whether the system is anti-corrosive, the material can be stainless steel or carbon steel, welded and formed, and processed by CNC boring and milling machine once after heat treatment. It is formed to ensure that the center distance between the two rotors and the concentricity of the front and rear bearing positions meet the design requirements; the working cavity is equipped with a spray device for gas cooling and rotor sealing; the gas inlet and outlet directions are generally upward and downward, and can also be arranged according to the system. The cloth needs to be made in the form of top in and side out.
