Key configuration and selection of the hydrocarbon solvent recovery device
Select key configurations to optimize the user experience.
With the same processing capacity, different configurations will result in significantly different usage efficiency and convenience.
I. Vacuum system: lowers boiling point, saves energy, ensures safety, and improves the recovery rate of high-boiling-point solvents. Recommended configuration, especially when the solvent boiling point is > 150℃.
II. Heating method: 1. Indirect heating (such as heat transfer oil): uniform, safe, avoids local overheating. 2. Direct heating: low cost, but has safety risks.
Opt for indirect heating, which is the industry's mainstream safe design.
III. Cooling system: 1. Air cooling: installation is simple, no need for external water source. 2. Water cooling: high cooling efficiency, suitable for scenarios with large processing capacity or high environmental temperatures.
Choose based on on-site conditions and processing capacity. Air cooling is more convenient, while water cooling is more efficient.
IV. Automation level: 1. Automatic feeding and discharging: reduces manual contact, improves efficiency. 2. Automatic slag removal: significantly reduces labor intensity for cleaning slag. 3. PLC/IoT control: enables remote monitoring, data recording, and fault warning.
With budget permitting, the higher the automation level, the better, as it helps achieve stable operation and refined management.
V. Convenience of slag removal: 1. Dumping-type bucket: easy to clean. 2. Downward slag discharge port: can be connected to a pipeline for continuous slag discharge.
When handling viscous or highly solid-containing waste liquids, consider the convenience of slag removal.
VI. Official explosion-proof certification: ensure that the entire machine and all electrical control components (electrical control box, motor, heater, sensor, etc.) have a nationally recognized explosion-proof certificate (such as China CNEX), with explosion-proof marks such as Exd IIB T2/T3/T4 Gb.
Core security design:
Fully explosion-proof structure: Prevent any components that may generate electric sparks from coming into contact with the solvent.
Multiple protections: Must include over-temperature protection, over-pressure protection, power failure protection, and audible and visual alarm functions.
High-quality sealing: Utilizing integral Teflon and other high-temperature-resistant and corrosion-resistant sealing rings to ensure no leakage.
