A set of compression condensation membrane separation equipment, while solving the environmental standards and solvent recovery two problems

VOCs waste gas treatment, many companies face a dilemma: both to ensure that emissions standards, but also do not want to waste high-value solvents in the exhaust gas. Traditional crafts often only care about one end--activated charcoalandRTOIt can meet the standard, but the solvent is either adsorbed into hazardous waste or burned directly. The recovery efficiency of single condensation is limited, and the concentration of tail gas may not be able to meet the emission requirements stably.

The compression condensation membrane separation equipment does these two things together.

The front end of the equipment is a condensing unit. The exhaust gas enters the condensation system after being pressurized by the compressor, and the condensation temperature is controlled according to the boiling point of the solvent. Most of the organic matter directly changes from gaseous to liquid and is discharged through the collection tank. This step completes the main work of solvent recovery, and the recovered liquid can be directly reused for production.

The back end of the equipment is the membrane separation unit. The condensed tail gas still contains a small amount of unliquefied organic matter. This part of the gas enters the membrane module, and the difference in permeation rate between organic molecules and air molecules in the membrane material is used-organic molecules preferentially permeate the membrane layer to form concentrated gas and send it back to the compressor inlet. After being mixed with fresh waste gas, it enters the condensation unit again for circulation treatment. Air components are intercepted and discharged up to standard. This step ensures that the concentration of the tail gas meets the environmental requirements, and at the same time, the residual organic matter is "fished" clean to form a closed cycle.

One set of equipment, two functions. The front section recovers the solvent to create value, and the back section checks the discharge to ensure compliance. The equipment is electrically powered, does not burn gas, requires no activated carbon consumables, and generates no hazardous waste. The skid-mounted design completes the assembly and debugging before leaving the factory, and the site can be put into operation only by connecting the power supply and gas circuit. The PLC runs fully automatically without special personnel on duty.

For VOCs waste gas with medium and high concentration and recovery value, the compression condensation membrane separation equipment is in place in one step, and the environmental protection standard and solvent recovery are completed at the same time. Luoyang Wo Hong focuses on this process and can match the scheme according to the exhaust gas parameters. First, conduct a condition test and let the data speak.
