Skid-mounted condensing membrane separation with small air volume and high concentration waste gas recovery, suitable for laboratory

In small air volume exhaust gas scenes such as laboratories, pilot workshops, and small production lines, the air volume is usually between tens to hundreds of cubic meters per hour, with many types of solvents, large concentration fluctuations, and limited installation space. Large industrial equipment is not used,activated charcoalThe adsorption efficiency is low, the carbon change is frequent, and the direct discharge is facing the pressure of environmental protection. Skid-mounted condensing film separation small air volume unit is a special device designed for this kind of scene.

Skid-mounted structure, ready-to-use on site

The unit adopts a skid-mounted structure. The compressor, condenser, membrane module, and control system are all integrated on the steel base. The shape is compact. The width of the whole machine usually does not exceed one meter and the depth is about half a meter. It can be placed next to the fume hood, the side of the test bench or the corner of the workshop without a separate equipment room. Complete the assembly and commissioning before leaving the factory. The site only needs to turn on the power supply and connect the exhaust gas inlet and exhaust pipe to run. The installation time is counted by hours. The whole machine is light in weight and designed with casters, which can move the position at any time according to the experimental layout changes.

Compression condensation + membrane separation, recovery rate above 90%

The process adopts the combination of compression condensation and membrane separation, which is consistent with the principle of industrial grade equipment. The exhaust gas enters the multi-stage condensing unit after being pressurized by the compressor, and the solvent is liquefied into liquid through graded cooling, and flows into the collection bottle. The condensation temperature can be adjusted on the touch screen according to the type of solvent used on the same day-set one temperature for acetone for chromatography and another temperature for dichloromethane for synthesis.

After condensation, the tail gas enters the membrane module.gas separation membraneTaking advantage of the difference in permeation rate between organic molecules and air molecules in the membrane material, solvent molecules preferentially permeate through the membrane layer to form concentrated gas, which is sent back to the compressor inlet and mixed with fresh exhaust gas before entering the condensation process again; the air is trapped and discharged to the standard. Through this cycle design, the capture efficiency of the system is significantly improved. The recovery rate of acetone, dichloromethane, ethyl acetate, ethanol, toluene and other common solvents can reach more than 90%, and the export concentration can meet the recommended standards for laboratory exhaust emissions.

Low noise, no carbon exchange, no hazardous waste production

The operating noise is controlled at a low level and does not affect the experimental environment. The equipment is driven by electricity, does not consume natural gas, does not replace consumables such as activated carbon, and does not produce hazardous waste. The process is normal temperature to low temperature operation, does not involve combustion, no open flame, and has good safety in the laboratory environment. PLC automatic control, there is gas on the work, no gas on standby, no need to watch.

Selection recommendations

For small air volume exhaust gas scenarios that are not suitable for large equipment, the skid-mounted condensing membrane separation unit is a flexible, economical and compliant choice. Before selection, it is recommended to complete the working condition test to obtain the basic parameters such as solvent type, concentration and air volume. LuoyangWohong PetrochemicalEquipment Co., Ltd. can provide the whole process service from detection to delivery according to the specific solvent type and processing air volume matching device specifications of the laboratory or small production line. First, conduct a condition test and let the data speak.
