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.
2, Working Principle
Temperature control system 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 45ºC higher than the boiling point, and the maximum heating temperature does not exceed 200ºC.
Steam temperature setting: Set the temperature below 10ºC 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 20ºC higher than heating. If the heating system is abnormal and heated to this temperature, the overtemperature protection device will shut down the machine.
Working flow:
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. 3, Introduction to Operation
I. System features: automatic feeding, pneumatic discharging, one-time slag removal and automatic recover equipment.Complete equipment includes: 1. Automatic feeding device (Explosion-proof liquid level monitoring, explosion-proof pneumatic diaphragm pump) 2. Pneumatic discharging device (self-installed function of vacuum pump) 3. Pneumatic slag removal device (pneumatic ball valve)
4. Equipment operation process 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.
5. Technical parameters of H-500 solvent distillation equipment (1). Machine name:WSDautomatic solvent recovery equipment (2). Machine dimension: 1620x930x1607 mm weight:450kg (3). Machine power: 33KW (4). Power supply: 380V 50-60Hz (5). Air source: general compressed air, more than 4KG (only a small amount of compressed air is used to drive the pneumatic valve) (6).capacity: Single feed 200L, distillation speed above 150L/H (7). Shutdown control mode: 1. Automatic control 2. Time control (set a fixed time to automatically shut down the machine) (8). Feeding and discharging method: automatic continuous feeding and continuous discharging. (uninterrupted discharge) (9). Pressure protection: If the pressure in the tank exceeds 0.3KG outside, the top cover safety valve of the machine will automatically decompress and the pressure sensor will automatically transmit the signal to the control module (the equipment pressure is displayed in real time), and the equipment will automatically alarm and stop working to prevent The equipment is still working after the safety valve is automatically decompressed, which is safer and more reliable (10). Barrel body and shell: stainless steel SUS304, high temperature resistance and corrosion resistance; the heating barrel cover is provided with a circular window (diameter 150mm) for easy observation (11). Lid pressing method: locking by lever principle (no need to open the barrel cover under normal operation of the equipment) (12). Heating method: The heating medium oil is used for circulating heating to ensure that the heating surface of the tank is uniform. (14). Heating temperature: It can be heated at a temperature lower than the boiling point of the recovered solvent (15). The internal structure of the barrel: the company's unique spiral anti-foaming structure design prevents the phenomenon of foaming and recovers the pure solvent (16). Residue removal: Pneumatic lower slag discharge system, simple and convenient (17). Cooling system: water-cooled cooling method is adopted to minimize solvent volatilization
