The working principle of MVR-DTB forced circulation evaporator is mainly based on mechanical vapor recompression (MVR) technology and forced circulation flow. In the system, the secondary steam generated by the evaporator is compressed by a high-efficiency compressor to increase its temperature and pressure, and then sent back to the evaporator as a heat source to form a heat cycle. At the same time, the feed liquid is forced to circulate under the action of the pump, and through heat exchange with steam through the heating tube bundle, the moisture in the feed liquid evaporates rapidly. This forced circulation method ensures that the liquid is uniformly heated in the evaporator, avoiding local overheating or scaling problems and greatly improving evaporation efficiency.
In the MVR-DTB forced circulation evaporator, DTB separation technology plays a key role. It utilizes a special separation structure to achieve effective vapor-liquid separation of materials in the separator, while preventing crystal particles from entering the heat exchange tubes, thereby ensuring the stability and continuity of the evaporation process.
1、 Equipment advantages
1. Wide applicability: MVR-DTB forced circulation evaporator is mainly suitable for materials that are prone to scaling during the evaporation process, materials with crystal precipitation during the evaporation process, materials with viscosity increasing with concentration, and materials with insoluble solids.
2. Uniform heating: During the evaporation process, the material is heated by forced circulation, resulting in a fast flow velocity (flow rate of 1.0~2.0m/s) in the pipeline, uniform heating, high heat transfer coefficient, and prevention of dry wall phenomenon.
3. Good vapor-liquid separation effect: After being rapidly heated by the heater through forced circulation, the feed liquid comes out from the top and enters the evaporator separator tangentially, with good vapor-liquid separation effect.
4. Easy to operate: The MVR-DTB forced circulation evaporator has a compact structure, small footprint, smooth layout, and can be automatically or manually controlled, with fast start-up and flexible mode switching.
5. Efficient and energy-saving: Due to the MVR technology achieving the cyclic use of heat, energy consumption is significantly reduced, making the MVR-DTB forced circulation evaporator highly efficient and energy-saving.
II. Application Fields
MVR-DTB forced circulation evaporator has a wide range of application scenarios in multiple industries, such as:
1. Pharmaceutical industry: It is used in the process of liquid medicine concentration, extraction of plant essence, and preparation of biological products.
2. Food industry: used in the production process of liquid foods such as concentrated fruit juice, dairy products, seasonings, soups, etc.
3. Chemical industry: used for the concentration, purification, and crystallization of various chemical solutions, such as the production of chemical raw materials such as sodium chloride and sodium persulfate.
4. Environmental protection industry: used to treat wastewater from industries such as electroplating, surface treatment, printing and dyeing, papermaking, etc., by concentrating inorganic and organic salts to meet discharge standards or achieve reuse.
4、 Notes
1. Water quality requirements: The MVR-DTB forced circulation evaporator has certain requirements for the inlet water quality. If the water quality is poor, it may be necessary to add pre-treatment equipment to avoid damage to the evaporator or affecting the evaporation effect.
2. Equipment maintenance: The steam compressor is a key component of the MVR-DTB forced circulation evaporator and requires regular maintenance and upkeep to ensure its normal operation and extend its service life.
3. Operation training: Operators need to receive professional training to understand the working principle, operation methods, and precautions of the evaporator, in order to ensure safe and efficient operation of the equipment.
