Description

Technical Field

[0001] The invention relates to the field of MVR equipment, and in particular to a mobile intelligent material evaporation and crystallization test device. Background Art

[0002] MVR technical features: high thermal efficiency, energy saving, low power consumption. The energy consumption of evaporating one ton of water is only one-fourth to one-fifth of that of a traditional evaporator. The energy saving effect is very significant. Low operating cost. The energy consumption of MVR evaporator is generally one-third to one-fourth of that of a traditional multi-effect evaporator. The saved operating cost will be a large profit for the company.

[0003] Clean energy, no pollution. MVR evaporator can run as long as there is electricity. It uses industrial power supply, and there is no problem of carbon dioxide emission. No steam, no boiler, no coal and oil, no chimney, no cooling water, no CO2 and SO2 emissions. If MVR evaporator is used in large quantities, it will bring a lot of CDM income to the country. Through the secondary steam recycling technology, the COD and BOD values ​​of steam condensate and the ammonia nitrogen content are much lower than the indicators of traditional multi-effect evaporators, and they fully meet the national emission standards.

[0004] It adopts single-stage vacuum evaporation with low evaporation temperature, which is particularly suitable for materials with strong heat sensitivity and is not easy to denature the materials. It adopts low-temperature negative pressure evaporation (50-80℃) to prevent the high-temperature denaturation of the evaporated materials. MVR evaporator is a replacement product of traditional multi-effect falling film evaporator. All materials and processes applicable to single-effect and multi-effect evaporators are suitable for MVR evaporator, which is completely replaceable in technology and has better environmental protection and energy-saving characteristics. It has a high degree of automation. MVR evaporator adopts industrial computer and PLC control system and frequency conversion technology, which fully realizes unattended automatic operation. Small size and mobility. Small and medium-sized MVR evaporators, with an area of ​​10 to 50 square meters, can be designed as a mobile structure for easy installation, commissioning and transportation.

[0005] When designing MVR evaporator equipment, you first need to know the material characteristics, such as material, concentration temperature, crystallization temperature, crystallization time and other key parameters. Generally, enterprises add water to dry materials, put them directly into containers, heat and observe, and judge the material concentration temperature, crystallization temperature and other parameters based on experience, and then design the pilot system. After obtaining the pilot results, they design the production process based on the pilot results and production capacity. The whole process takes a long time and requires a lot of debugging.
