With the rapid development of modern industry and the acceleration of urbanization, a large number of mining and utilization of water resources, wastewater treatment has become one of the issues of concern in today's society. MVR evaporator has been widely used in wastewater treatment. A lot of people are asking how much is the MVR evaporator? Do you know what factors affect the price of MVR evaporator?
In general, a complete set of MVR evaporator is composed of heater, separator, preheater, steam compressor, pump set, thickener, mother liquid tank, centrifuge, electrical instrument control, valve and pipeline
The price of MVR evaporator is also affected by materials, evaporator capacity, selected materials, materials of the whole equipment, and the price of pump and compressor of MVR evaporator power equipment.
In conclusion, when designing MVR evaporator, the following five factors affect the price of MVR evaporator:
1. Materials affect the choice of material of MVR evaporator
According to the different solubility of need to deal with waste material, selected the evaporator and the concentration of the main body of the material will be different, commonly used with titanium, 316 l, 304, 2205, and some not commonly used materials such as graphite, nickel, titanium is used more, also be relatively expensive, general situation of nickel price > titanium cost prices 316 l > > 2205 > 304 prices, the price of nickel material is relatively high, is due to the nickel has good chemical resistance, at room temperature, nickel surface covered with a protective oxide film, can resist the role of air, water, and some salt solution, Suitable for strong acid, strong base.
Generally, it is rare to use a large amount of nickel evaporator, and most commonly titanium materials are used. Generally, titanium materials are selected for chloride ions, but the PH value of chloride ions should not be too high or too low. Sulfur is generally made of 2205 materials, while 316L is mostly suitable for sulfur and phosphorus. 304 suitable for carbonated, milk, food.
2. Evaporation affects the size of MVR evaporator
In general, evaporation is directly proportional to the investment price of MVR evaporator system. The larger the evaporation, the larger the designed MVR evaporator will be, and the higher the price will be. Material concentration, composition, processing capacity and evaporation capacity determine the size of equipment, the number of efficiency and grade, the selection of steam compressor, the size of evaporation area, heat exchanger material, the cost of equipment investment.
3. The influence of evaporation temperature on the price of MVR evaporator
The lower the evaporation temperature is, the lower the vacuum degree MVR evaporation system needs to maintain. The sealing property of the system and the pressure (negative pressure) performance of the shell have certain requirements, which have higher requirements on the compressor.
4. Influence of heat exchanger area on price of MVR evaporator
The size of heat exchange area directly affects the price of MVR evaporator system. Because the traditional evaporator USES raw steam, the heat exchange temperature difference is large and the heat exchange area is relatively small. However, MVR evaporator is a small temperature difference, and when the total heat transfer amount is fixed, it must increase the heat transfer area at the cost of obtaining the same heat transfer effect and achieving the required evaporation amount.
5. Influence of pump selection on price of MVR evaporator
Pump is a complete set of MVR evaporators system's main power equipment, has a function in conveying liquid MVR evaporation system of discharging pump, feed pump, circulating pump, fresh water pump, different pump have different functions, the price range will have the difference, how to reasonably choose the pump, should consider various comprehensive index of the pump unit, the flow of the stand or fall of pump mechanical seal, runtime, and suction head, good cavitation resistance and corrosion resistance will have an effect on the evaporation system.
