““Soil” says evaporator
Thread Content
Everyone finds evaporators to be quite mysterious; in simple terms, it’s like using a large pot to cook rice porridge – turning a liquid into a thicker substance. To achieve this thickness, some water must be evaporated; to make the solution crystallize, it needs to be supersaturated. It’s just that the method of evaporation differs. In order to save resources and avoid wasting the limited energy resources left to us by our ancestors, multi-effect systems involve using the same amount of steam multiple times, while MVR systems involve compressing the steam to increase its temperature so that it can be reused. But there is nothing he can do about materials with higher boiling points; in any case, evaporation requires a temperature difference – only with a temperature difference can condensate water be produced, and it is the presence of this condensate water that allows the solution to thicken or crystallize. There are many products on the market aimed at attracting users, with claims about how good their devices are and how energy-efficient they are. For example, it is claimed that with MVR technology no steam is needed; the system can achieve evaporation at 85°C. Yet if you ask the customer to heat the material to 85°C, how can the condensate water generated during the heating process from room temperature to 85°C actually be used to heat the material to that temperature? Also, is there no heat loss in your insulation? Be honest in business! ! I speak in a straightforward manner, honest and sincere; I hope that honest people will get in touch with me, Zhang, at 15830976988, so that we can all contribute to our environmental protection efforts.
By \"no steam needed,\" does it mean that there is no need to add fresh steam? The amount of steam required by all the equipment, as well as the evaporation temperature, are managed through continuous circulation by the compressor. According to you, even with a compressor in use, is it still necessary to keep supplying fresh steam? Then who would buy your compressor? Won’t they use multi-effect technology?
Preheating with condensate water and adding a small amount of steam – that’s the correct approach. Saying nothing about adding steam is just a lie.
Do you deny the energy-saving efficiency of MVR evaporation equipment?
The materials fed into the system are preheated to the evaporation temperature; however, to ensure stable and continuous operation and take into account heat losses in the system, a small amount of fresh steam is still needed as a supplement； Multiple effects also require makeup steam, only the preheating steam and the makeup steam are combined into one.

Where does the thermal energy needed to heat the material from room temperature to the evaporation temperature come from? I should inform the customer that I need materials at 80 degrees to be fed into my system; I don’t necessarily need steam for this. Our system doesn’t require the use of steam. The customer might think it’s just a matter of using room-temperature materials, but in reality, quite a lot of steam is required to raise the temperature from room temperature to the evaporation temperature.
