Forced circulation evaporator - crystallizer wastewater evaporator

Forced circulation evaporatorMain features:

1. The equipment has a wide range of adaptability to the characteristics of the materials it processes. This mainly targets materials that are prone to scaling during the evaporation process, materials that undergo crystal precipitation during the evaporation process, materials that increase in viscosity with increasing concentration, materials with insoluble solids, etc;
During the evaporation process, the material is heated through forced circulation, resulting in fast flow velocity, uniform heating, high heat transfer coefficient, and prevention of dry wall phenomenon inside the tube.
3. The feed liquid is quickly heated by the heater through a forced circulation pump, and then directly enters the evaporator separator in a tangential manner from the top, resulting in good vapor-liquid separation effect.
4. The material is concentrated by vacuum low-temperature evaporation, coupled with continuous feeding and discharging, with short heating evaporation time, suitable for thermosensitive evaporation concentration of food sauces (such as tomato sauce, peach juice, apricot juice, carrot sauce, apple sauce, kiwi sauce, etc.).
5. The equipment has a compact structure, small footprint, smooth layout, easy operation, and stable performance.
6. The equipment can be equipped with an automation system to achieve automatic control of feed quantity, heating temperature, and discharge concentration. It can also be equipped with protective measures for sensitive materials in case of sudden power outages or malfunctions, as well as other automated operations and controls such as safety and alarm.

How to maintainForced circulation evaporator？
The lubricating oil for the gearbox is 40 # engine oil, and the amount of oil added should be within the indicated height. Excessive oil volume can cause stirring and heat generation, while insufficient oil volume can lead to oil film damage and heat generation in eccentric shaft pumps, resulting in temperature rise.
1) Replace the lubricating oil within 1 month of use, and replace the lubricating oil every 3-4 months thereafter.
2) After opening the low head, unscrew the bolt at the bottom of the rotor U-shaped groove and replace the scraper every four months.
3) Open the bottom bearing every two months, check the wear of the bottom bearing, and replace it if necessary.
4) According to the properties of the material, the inner cylinder should be regularly soaked and cleaned with warm water or solvent.
5) Add sealing fluid to the mechanical seal chamber once a month, using 20 # mechanical oil as the sealing fluid
The characteristics are:
① The evaporation capacity can reach 0.5t/h~100t/h
② During normal operation, the system only uses electricity, and the energy consumption for evaporating one ton of water ranges from 15KW. h to 100KW. h. Its operating cost is 1/8 to 1/2 of that of multi effect evaporation.
③ It is currently a more energy-efficient evaporator, mostly single effect evaporation, with small heating temperature difference and short residence time, suitable for heat sensitive materials.
④ Compact structure and small footprint.
⑤ The equipment is controlled by PLC to achieve automatic operation and can operate continuously and stably for a long time.
