MVR evaporation equipment is needed in the treatment of high salt wastewater and high salt wastewater. The energy saving of MVR evaporation equipment should be analyzed from economic benefits. The annual operation cost of MVR evaporation system includes power consumption of compressor, preheating steam consumption, cooling water of compressor, etc. The following by the small to give you a detailed introduction of MVR evaporation system equipment how to save energy?
1. In fact, the function of MVR evaporation equipment is to improve the taste of steam, not to create energy. It is to compress the secondary steam in the evaporation process with a steam compressor, increase its temperature and pressure, and use it as a heat source again to heat the materials to be evaporated, so as to achieve the purpose of recycling steam. In the evaporation process, no additional steam is needed, only a small amount of electric energy is needed In order to obtain more heat energy.
2. MVR evaporation system equipment is based on recycling the latent heat of secondary steam generated by material evaporation. Since the latent heat required for secondary steam in the evaporator comes from the latent heat released by the condensation of the exhaust steam itself, the energy consumed by evaporation is only the power consumption of the compressor.
3. The energy saving of MVR evaporation system equipment is reflected in that it only needs to input 16kj (tons of water) to make the secondary steam from useless to useful. At the same time, it is reflected in the comparison of steam price and electricity price. The electric quantity is directly related to the model of the selected motor, compressor, centrifuge and other systems.
