Low Temperature Evaporation V-CT-ST-1000 | China Suppliers and Factory for 45 L/h Evaporative Power
Evaporation refers to the process of vaporization that occurs on the surface of the liquid, usually referring to the process of vaporizing a part of the solvent in the solution by heating the solution to increase the concentration of non-volatile components in the solution or the process of crystallizing the solute from the solution. Generally, the higher the temperature and the larger the liquid surface exposure area, the faster the evaporation rate. The lower the surface pressure, the faster the evaporation rate. In order to pursue the purpose of high efficiency and low energy consumption, evaporation equipment mainly develops in the direction of high heat exchange efficiency, efficient use of heat, high heat exchange area and high vacuum degree, so two categories of low-temperature evaporation equipment based on multi-effect evaporation technology and mechanical steam recompression technology have gradually formed.
Low temperature evaporation technology has been more common in our daily production and life, such as seawater desalination, fruit juice concentration, monosodium glutamate manufacturing, etc., and other aspects of wastewater salt separation, cutting fluid reduction, electroplating waste liquid concentration, mother liquid concentration and drying, landfill leachate drying, hazardous waste reduction, etc. These not only boast of the essential characteristics of evaporation but also boast of the lower and lower operating costs of low temperature evaporation technology.
Continuous evaporation mode, no system venting and shutdown, more energy-saving and efficient.
When it comes to evaporation, it is not impossible to talk about energy consumption, and it is generally known that evaporation is a large energy consumer in the industrial process. Especially for the evaporation of water, the specific heat of water and the heat of evaporation are very large, whether it is the evaporation preheating stage or the vaporization stage, it needs to consume a lot of energy. In theory, the evaporation of a ton of waste water needs to consume a ton of steam (fresh steam costs between 100-300 yuan), if the calculation of the heat loss problem, the actual evaporation of a ton of water needs to consume more than 1.2 tons of steam. With such a high energy consumption, the operating cost has become a hindrance to the application of evaporation technology, if it is not required by the main process of product production, presumably no company is willing to spend such a big price to do thankless things.
Low temperature evaporation technology should be an important means to solve the problem of energy consumption at this stage, it integrates a variety of technologies in a body to strengthen the evaporation conditions so that the evaporation can be completed at a relatively low cost.
Frequently Asked Questions (FAQ)
Q: What factors affect the rate of evaporation?
Generally, the higher the temperature and the larger the liquid surface exposure area, the faster the evaporation rate. Additionally, the lower the surface pressure, the faster the evaporation rate.
Q: What are the main types of low-temperature evaporation equipment?
Evaporation equipment mainly develops in the direction of high heat exchange efficiency, efficient use of heat, high heat exchange area, and high vacuum degree. This has led to the formation of two main categories: multi-effect evaporation technology and mechanical steam recompression (MVR) technology.
Q: What are the common applications of low-temperature evaporation technology?
It is widely used in seawater desalination, fruit juice concentration, monosodium glutamate manufacturing, wastewater salt separation, cutting fluid reduction, electroplating waste liquid concentration, mother liquid concentration and drying, landfill leachate drying, and hazardous waste reduction.
Q: Why is traditional industrial evaporation considered high in energy consumption?
Water has a very large specific heat and heat of evaporation. In theory, evaporating a ton of wastewater consumes a ton of steam (costing 100-300 yuan). When accounting for heat loss, the actual consumption exceeds 1.2 tons of steam per ton of water.
Q: How does low-temperature evaporation technology solve the energy consumption problem?
It integrates a variety of technologies to strengthen the evaporation conditions, allowing the process to be completed at a relatively low operating cost. Furthermore, it operates in a continuous evaporation mode with no system venting and shutdown, making it more energy-saving and efficient.
