DMF Waste Gas Recovery Plant
Equipment Description
In the light of the dry & wet production lines of the synthetic leather enterprises emitted DMF exhaust gas, the DMF waste gas recovery plant can make the exhaust reaches the requirements of environmental protection, and recycling the DMF components, using high performance fillers make DMF recovery efficiency higher. The DMF recovery can reach above 95%.
The device adopts the cleaning technology of spray adsorbent. DMF is easy to dissolve in water and water as its absorbent has low price and easy to gain and the water solution of DMF easy to rectify and separate to get the pure DMF. So the water as the absorbent to absorb DMF in the exhaust gas, and then send the absorbed DMF waste liquid to the recovery device to refine and recycle.
Technical Index

DMF Solvent Recovery Plant
Process brief introduction After the DMF solvent from the production process is preheated, it enters the dehydrating column. The dehydrating column is provided with heat source by the steam on the top of the rectification column. The DMF in the column tank is concentrated and pumped into the evaporation tank by the discharge pump. After the waste solvent in the evaporation tank is heated by the feed heater, the vapor phase enters the rectification column for rectif...
