Solvent Recovery System
Solvent recovery system, using the principle of distillation, by heating evaporation solvent into a gaseous vapor, vapor into the cooling system liquefaction outflow, so that the recovery of clean organic solvent. So that waste, dirty, old organic solvent regeneration, recycling and reuse. Not only saves a lot of procurement costs, but also reduces the pollution to the environment.
》Automatic feeding: (Explosion-proof liquid level monitoring, explosion-proof pneumatic diaphragm pump)
》Pneumatic discharging device (self-installed function of vacuum pump)
》One-time slag removal device (pneumatic ball valve)

The solvent recovery machine uses explosion-proof heater 6, with heat transfer oil 4 indirect heating, so that the heating temperature is uniform, and fundamentally solve the security of the heating process. Models with tank capacity above 200 liters are equipped with thermal circulation PUMP units
The temperature control is equipped with PLC and touch screen intelligent temperature control as follows:
Heating temperature setting: It depends on the boiling point of the solvent. Generally, the setting is about 45℃ higher than the boiling point, and the maximum heating temperature does not exceed 200℃.
Steam temperature setting: Set the temperature below 10℃ lower than the boiling point. When the solvent recovery is completed, the steam temperature sensor 1 will sense the temperature drop, and the machine will automatically shut down when the temperature drops to the set temperature.
Overtemperature protection setting: Set more than 20℃ higher than heating. If the heating system is abnormal and heated to this temperature, the overtemperature protection device will shut down the machine.
P1: The yellow area indicates the unheated conduction oil, Pour the solvent to be recovered into the distillation barrel
P2: The red area indicates the conduction oil in the heating, When the equipment is running, the temperature of conduction oil rises and the solvent is heated
P3: When the temperature reaches the boiling point of the solvent, the solvent starts to vaporize, and the gas flows into the cooler from the top of the distillation barrel, and then flows into the barrel after cooling (as shown in the blue area of the picture)
P4: After all solvents in the barrel are recovered, pour out the residue and the recovery process ends.
After confirming that the power supply and air source are connected correctly, start the operation button, the waste liquid is sucked into the recovery equipment through the automatic feeding system, the equipment runs fully automatically, and the residual liquid is discharged pneumatically, which truly achieves the purpose of automatic recovery, the equipment comes with network system, which can realize remote intelligent monitoring.
