Three effect falling film evaporator operating three effect falling film evaporator www.wzgoody.com/Product/zfq/574.html enrichment equipment belonging to the natural cycle of the film concentrator equipment, with the heat transfer rate, heating time is short, suitable for juice and dairy products. It is constructed by the top heater feed solution was added, liquid under gravity, into a film shape along the inner wall of the tube flows downwardly, due to the downward acceleration, the acceleration to overcome the pressure head or small than a membrane, boiling point elevation is also small heating steam and feed liquid temperature, and therefore a better heat transfer. Into the evaporator vapor-liquid separation chamber, separated secondary steam discharged from the top of the separation chamber, concentrated liquid withdrawn from the bottom. Multi-effect falling film evaporator in order to make the material liquid can be evenly distributed in each of the heating tubes, along the inner wall stream, so in the tube at the top or the tube mounting falling film distributor, the distributor plate, which is a perforated plate, which hole position, just staggered between the heater tube. Falling film distributor providing the heat transfer effect plays a significant role. In the falling film evaporator feed solution. After evaporation, the liquid stream basically reach the desired concentration. Therefore, the tube should be long enough to ensure that the heat transfer effect. Because solid-liquid heating time is short, it is beneficial for the protection of food nutrients, and secondly, it evaporates, a thin film is carried out, it can avoid the formation of bubbles, cleaning more convenient. Three effect falling film evaporator has a downstream process Process (and flow), countercurrent, Francis (crossflow) advection four forms: downstream: solution and steam flow to the same effect by a late order flow effect. Was pumped through a feed efficiency, relying on the pressure differential between the respective efficiency, flow automatically into the next effect, since the final effect complete solution (typically operate under negative pressure) pump out. Because of the latter effect, low pressure, the boiling point of the solution is also low, after the previous solution efficiency will flash when entering an efficient part of the water, resulting in a secondary vapor is greater, due to the higher concentration before aftereffect efficiency, low operating temperature often the first effect of the heat transfer coefficient is much higher than the final effect. Downstream flow is generally appropriate treatment in the case of high concentrations of heat-sensitive materials. Countercurrent: raw materials followed by the pump into effect before the end of the effect, a complete fluid discharged from the efficiency, solid-liquid and steam reverse flow. Generally suitable handle large changes in viscosity with temperature and concentration of the solution, not easy to deal with heat-sensitive materials. Francis: a combination of smooth countercurrent flow, both the advantages along countercurrent avoid its shortcomings, but the complexity of the operation, requiring a high degree of self-control. Stratosphere: each effect are feeding all the complete solution, each effect has crystallized, timely fractional crystallization, generally used for evaporation of a saturated solution. TNJM03 type evaporator series (ie, three-effect falling film evaporator) can be processed according to the characteristics of different materials, designs into different processes, can also be equipped with automatic control system according to different user requirements. With a concentration ratio (1 / 5-1 / 10), wide (<400cp) viscosity range, good heat transfer, large capacity, etc., suitable for heat-sensitive, high density, and viscosity of corrosive materials evaporation for corn syrup and starch industry bud table syrup, fruit juice and flavored semen food industry, dairy industry, milk, sugar syrup and alcohol industry sectors distillers filtrate concentrated. There pleiotropic upflow, downflow, falling film evaporator series equipment, corn syrup, fermented juice industry, juice, beverage industry, milk, wine tank filtrate, the pharmaceutical industry, fermentation liquid, high concentrations of organic or chemical wastewater The evaporative concentration of special equipment. With energy, heating time is short, evaporation higher viscosity materials applicable, concentration and concentration ratio, etc., also have access to high quality deionized water to meet the needs of industrial boiler water. And a combination of double effect, three-way, four-way and five-effect evaporator system. Can also take advantage of the top tube bundle or tray dryer exhaust steam and other heat sources of low calorific value (e.g., steam condensate) a heat source as an evaporator becomes a waste heat evaporator www.wzgoody.com, thereby greatly reducing the amount of generated steam, maximum energy savings. When there is adequate supply of waste heat steam, steam can be completely without students achieved significant economic benefits. Three effect falling film evaporator structural characteristics 1, three effect falling film evaporator is currently widely used products, but also our styling products, according to the evaporation capacity classification: Evaporation 1000 ~ 50000kg / h (series); 2, contact Material Material: all stainless steel SUS304 or 316L material; 3, the equipment from one, two, three at most efficient heaters, one, two, three at most effect evaporator separator, preheater, mixing condenser, hot pumps, vacuum pumps , material pump, balance tank, electric control boxes, tables and all piping, valves. 4, low steam consumption, 1kg 3.5kg of water vapor can evaporate. 5, the evaporation temperature is low, the second part of the steam jet by pressing the suction pump again next effect heaters, heat underutilized relatively low evaporation temperature. 6, concentration ratio, falling film evaporator, the viscosity of the liquid flow easily feed a large evaporation, is not easy to scale, concentrated short time, concentration ratio can reach 1: 5. 7, power supply, all incoming and outgoing material pumps, vacuum pumps and vacuum systems, such as control instrumentation and temperature instruments are confined to the operation control panel box control, automate production. Heat pump technology in falling film evaporator applications: the jet pump technology is to make use of low-quality energy conversion for high-quality energy saving effect can play. Forced circulation evaporator is more of a heat pump evaporators, heat pumps because of the advantages of no moving parts, not damaged, easy maintenance, but also facilitate the transformation of existing equipment and are widely used. But whether evaporation system with a heat pump but also according to the conditions provided by the specific circumstances, such as raw steam to choose. Steam consumption: consumption falling film evaporator with a heat pump system with steam consumption without the need for heat evaporation system of the Union.
