Forced circulation evaporators rely applied force circulation pump to circulate the liquid. It's heating chamber has both horizontal and vertical structures, liquid circulation pump speed by adjusting the size of this evaporator suitable for easy crystal, easy to scale concentrated solution, the main drawback is the large power consumption. Forced circulation evaporator can be divided into single-effect, double-effect, three-way, four-way and multi-effect forced circulation evaporator. Double-effect forced circulation evaporator vacuum enrichment equipment is my company developed energy-efficient enrichment equipment, which operate at low temperatures under vacuum, with a solid to liquid flow speed, fast evaporation, easy scaling and other characteristics. Suitable for high viscosity, high concentrations easy to scale enrichment materials, widely used in chemical crystallization, ketchup, jam, fruit juice and pulp of high concentration Diose processing concentrate production, has been widely used in the country, the better. According circulating evaporator feed liquid separation chamber and export of different positions, it can be divided into positive and reverse circulation forced circulation evaporator forced evaporator, circulating liquid feed import position in the export position of the upper is called positive cycle, and vice versa for the reverse circulation . Reverse cycle forced vaporiser has many advantages. Rely on the applied force - circulation pump to circulate the liquid. It's heating chamber has both horizontal and vertical structures, liquid circulation pump speed by adjusting the size of this evaporator suitable for easy crystal, easy to scale concentrated solution, the drawback is the large power consumption. Forced circulation evaporator structure and composition structure: each effect evaporator http://www.wzgoody.com, each efficiency separator, condenser, circulating pump, between efficiency pumps, vacuum and drainage systems, sub-cylinder, operating platform, electrical instrumentation control cabinet and valves, piping and other system components. Features 1. forced circulation evaporator concentrate vacuum evaporation temperature is low; 2. Adjust the feed material and the material balance of concentration, can be continuous feeding and discharging. 3. Take the material liquid forced circulation, viscosity, high concentrations of feed liquid flows easily evaporate, easy to scale, concentrated short time; 4. equipment to take the material forced circulation vacuum evaporation, reduce dwell time and improve thermal efficiency, extended equipment operation cycle, all stainless steel, with material contact parts made of polished or matte processing external pickling. Heater and separate evaporation chamber for easy cleaning and replacement of pipes, while reducing plant height. 5. The device consists of one, two, three or more heaters, one, two, three, and more evaporative crystallization separation chamber, the circulation pipe, vapor-liquid separator, mixing condensers, vacuum pumps, thick paste the feed pump, one, two three, multi-effect forced circulation pumps, condensate pumps, electric control boxes, table and all the piping, valves, meters and other components. 6. Heater: heating tube heaters are made of stainless steel, an efficient steam heating steam for a living, the second effect of a secondary steam heater for crystallization chamber isolated effect as a heat source, the material was separated by two-effect evaporator enters through the lower end of the cone effect forced circulation pumping until the bottom of the heater to enter from the upper heater tangentially into the separation chamber into the second effect evaporator, this continuous cycle, concentration of the process, from the return pipe portion materials continue to slowly turn To add an effect within the flow tube, a material effect forced circulation pump will be increased by another bend to enter inside the heater through the first heater tube, the heated material was dropped from the tube, tangentially into the evaporator separation chamber, improve the gas-liquid separation; after normal operation feed rate must equal the amount of each effect evaporator and the quantity sum. 7. evaporative crystallization separation chamber: the evaporation chamber upright cylinder, the lower end is tapered to facilitate crystal slurry discharge. Secondary steam discharged from the top, by the vapor-liquid separator into the condenser, the conical bottom of the evaporator chamber is connected to the circulation pump. 8. Separators: The main role is to prevent the evaporation of fine droplets formed in the process of being entrained secondary steam to escape. For vapor-liquid separation, can reduce the loss of feed solution, while preventing contamination and cooling water pipes. Secondary structure is mainly in the vapor flow through the channel, provided with a plurality baffle, so that the secondary steam with droplets, a sudden change direction several times while collide with baffles, due to droplet inertia, a sudden change in When the flow, steam flow begins rejection to, so as to achieve the vapor separation. The main condenser is bulky secondary steam evaporated during the vacuum generated by the cooling action of water condensed to a liquid, the concentrate smoothly, there is a separation of the secondary steam and non-condensable gases in the cooling water, to facilitate vacuum extraction means, in order to reduce the volume load of the vacuum system, to ensure the desired degree of vacuum. Its structure mainly by the mixing chamber, the gas-liquid separator, pressure legs and other components. A circulation evaporator performance, complete system design aesthetic reasonable, stable operation, high efficiency, low consumption of steam; concentrate ratio, forced circulation, so that the viscosity of the feed liquid flows easily evaporation, condensation time is short; 2, special design simple operation can be achieved switch to change effect, in order to adapt to different products; 3, the evaporation temperature is low, the heat is fully utilized, the material was heated gently for concentrating heat-sensitive materials; 4, the evaporator through forced circulation, heat in the pipe uniform heat transfer coefficient, to prevent "dry wall" phenomenon; 5, solid-liquid separation and then into the separator, and strengthen the separation, so that the overall device has a greater operating flexibility; 6, compact package of the device structure, covers Small, simple and smooth layout represents the development direction of large sets of evaporation equipment; 7, continuous access to materials, solid-liquid level and the concentration required to achieve self-control;
