[0002] 1,3-Dioxolane is an organic compound with the chemical formula C3H6O2. It is a colorless, transparent liquid that is soluble in water, ethanol, ether, and acetone. It is an excellent organic solvent and is often used as a solvent for oils and fats, an extractant, an electrolytic solvent for lithium batteries, and a chlorine-based solvent stabilizer.

[0003] At present, a lot of tail gas is generated in the production process of dioxolane. Chemical tail gas often contains many types of pollutants with complex physical and chemical properties and different toxicities, which seriously pollute the environment and affect human health.

At the same time, the controller controls the suction fan 12 to work so that the exhaust gas can flow from left to right along the inside of the treatment box 1 and pass through the filter for purification and filtration. After the purification and filtration, the exhaust gas is immediately introduced into the incineration equipment for secondary purification, and finally the gas that meets the standards is discharged to the outside. As the filter is used, a lot of impurities will be attached to form a blockage. Then, the electric push rod 33 is first controlled by the remote control to work, and then the limit plate 35 can be separated from the installation frame 41 to release the clamping, and then the installation frame 41 can slide inside the treatment box 1. At this time, you only need to hold the handle 45 and pull the sealing plate 44 outward to make the installation frame 41 gradually separate from the treatment box 1 to the outside.

When the slide groove 31 is completely separated from the installation frame 41, the installation frame 41 can be taken out immediately. At this time, the remote control is operated to cut off the power of the electromagnet 43, and then the filter net can be quickly removed. The filter net is not shown in the figure. After it is removed, a new filter net is replaced. After the replacement is completed, the remote control is operated again to re-energize the electromagnet 43. At this time, the filter net can be firmly adsorbed on the supporting edge 42 again, and then the installation frame 41 is put into the slide groove 31 and between the two limit blocks 32 again and slid and pushed. When the installation frame 41 contacts the rear wall of the treatment box 1, the remote control is operated again to realize the automatic clamping position limitation of the installation frame 41.
