Product description of concentrator

The concentrator is suitable for the concentration of liquid materials such as traditional Chinese medicine, western medicine, glucose, starch, monosodium glutamate, dairy food and chemical industry, especially for the concentration of heat sensitive substances in low temperature and vacuum Customers can choose series concentrators in technical parameters according to the concentration volume Features: 1 Multiple utilization of primary steam and effective heat preservation of the superheated condensate from the evaporator make the consumption of heating steam greatly reduce the consumption of heating steam less than 0.4KG for 1kg water evaporation 2 The evaporator and the condensate storage are of overlapping structure, so the whole set of equipment is compact and covers a small area 3 The advection evaporation process based on external heating or natural circulation is adopted, with large circulation, high evaporation speed, short heating time, not easy to coking and easy to clean 4 Using vacuum evaporation operation, not only the evaporation capacity is large, but also the materials can be evaporated at a lower temperature to meet the concentration requirements of heat sensitive materials 5 New type of gas separation device is adopted, which has no running off phenomenon and high product yield In a word, the device is a new energy-saving three effect concentration tank, which can be widely used in high concentration concentration concentration of materials in chemical, pharmaceutical, food and other industries Operation specification: 1 Necessary work before startup: ① check whether the heaters and evaporators are clean ② check whether each valve is in the correct open and close position 2 Start up: ① open the vacuum valve ② open the feeding valve and close the feeding valve when the feeding liquid is seen in the sight glass ③ before opening the steam valve, first open the steam blowdown valve, discharge the residual condensate and dirt in the steam pipe to the sewer, and close the steam blowdown valve ④ slowly open the steam valve, raise the temperature and heat to the required pressure, so that each effect evaporator can carry out thermal cycle ⑤ open the cooling valve of the condenser (if the vacuum pump of water jet condensation is used for direct condensation, this item will be cancelled) 3 Normal operation: ① adjust the opening degree of each effect feed valve to control the material level to maintain a certain height ② open the exhaust valve of the heater once every 2 hours of evaporation to remove the lower condensable gas ③ for the discharge of condensed water, except for the single discharge of condensed water from the effect I heater, the Effect II and effect III shall be discharged once about half an hour The discharge steps are as follows: A close the water valve, i.e the intermediate valve between the heater and evaporator and the intermediate valve between the water receiver B open the vent flash valve to change from vacuum to exhaust C open the drain valve at the bottom of the water receiver, discharge the condensate, and then operate normally according to the position 4 Receiving operation: ① close the II and III effect feeding valves ② close the vacuum butterfly valve of effect III evaporator and open the bypass valve of effect I vacuum to improve the vacuum degree of effect I evaporator ③ open the vacuum valve of the lower reservoir of the I-Effect evaporator ④ open the drain valves of Effect II and effect III, destroy the vacuum degree of Effect II and effect III evaporators, open the bottom drain valve of Effect II and effect III heaters, pump all the feed liquid into the storage tank at the bottom of effect I evaporators, and close the valve of Effect II and effect III ⑤ heat cycle the feed liquid separately in the first effect, and evaporate to the required depth to discharge the feed 5 Shutdown: ① close the steam valve and stop the steam supply ② close the vacuum valve and stop the operation of the vacuum pump ③ open the exhaust valve of the evaporator to destroy the vacuum degree of the evaporator ④ open the exhaust valve and drain valve to drain the condensate.
