Overview

MVR evaporator (mechanical vapor recompression) abbreviation. MVR is a technology that reuses the energy of the secondary steam it generates, thereby reducing the demand for external energy.

The secondary steam, after being compressed by the compressor, increases the pressure and temperature, and the heat enthalpy increases accordingly. It is sent to the heating chamber of the evaporator to be used as heating steam, that is, raw steam, so that the material liquid maintains the evaporation state, and the heating steam itself transfers heat to the material itself and condenses into water. In this way, the steam that was originally going to be discarded is fully utilized, latent heat is recovered, thermal efficiency is improved, and raw steam is saved.

Features

1. MVR energy-saving evaporator technology is currently the most advanced evaporator technology in the world. It only requires a very small amount of steam (a small amount of primary steam is required when starting up, and almost no primary steam is needed during normal operation), which greatly reduces the operating costs of enterprises and reduces environmental pollution.
2. Due to the use of a compressor to provide heat source, the temperature difference is much smaller than that of a traditional evaporator, which can achieve gentle evaporation, greatly improving product quality and reducing scaling.
3. No condenser is needed or only a small area of condenser is needed. The structure and process are very simple. It is fully automatic operation, can run continuously, and is safe and reliable.
4. The equipment is equipped with CIP cleaning pipelines, which can realize on-site cleaning. The entire equipment is easy to operate, has no dead ends, has a high degree of automation and operates smoothly.
5. This evaporator evaporates the material at a low temperature (evaporation temperature 50℃-95℃) and is not prone to foaming. The material liquid is uniform, does not run out, is not easy to coke, and the material has minimal heating denaturation.
6. Although the initial investment amount is relatively high, the return on investment of most projects is generally 1.5 to 2 years, and no more than three years at most.
7. Compact structure and small footprint.
8. Evaporating one ton of water consumes 20-50kw/h.

Application

1. Chemical industry: MVR evaporator can be used for solvent recovery, drug extraction, waste gas treatment, etc. Through the evaporation process, organic solvents can be recycled, effectively reducing solvent consumption and emissions, thereby achieving the goal of energy conservation and environmental protection. It can also be used to produce high-purity chemicals such as salt, sodium nitrate, etc.
2. Pharmaceutical industry: In the pharmaceutical process, MVR evaporator is used to concentrate pharmaceutical liquids, concentrate plant extracts, and recover organic solvents, etc. It can effectively evaporate the solvent in the pharmaceutical liquid, improve the purity of the drug, and meet the high requirements of the pharmaceutical industry for product quality.
3. Food industry: MVR evaporator, used for concentrated fruit juice, dairy products, sauces and other foods. Through evaporation, the water in the food is removed, thereby improving the taste and shelf life of the food.
4. Environmental protection industry: MVR evaporators are also widely used in the field of environmental protection and are used for wastewater evaporation, concentration or crystallization treatment. Its advantages are that it can significantly reduce energy consumption, improve production efficiency, and achieve environmental protection goals at the same time, so it has been widely used and recognized.
