Polyethylene is odorless, non-toxic, feels like wax, has excellent low-temperature resistance (the lowest operating temperature can reach -100 to -70°C), and good chemical stability. Because the polymer molecules are connected by carbon-carbon single bonds, they can withstand the corrosion of most acids and alkalis (not resistant to oxidizing acids), are insoluble in general solvents at room temperature, have low water absorption, and have excellent electrical insulation.

[0003] According to the Chinese utility model disclosure specification "CN208642227U", "The utility model performs pressure swing adsorption separation and concentration on the tail gas by sequentially connecting the tail gas pipeline with the high and low pressure cooling condensation recovery unit, the coarse and fine filtration unit, the pre-purification unit, and the tail gas after the pressure swing adsorption separation and concentration, and the vacuum pump is set to facilitate the pressure swing treatment in the main box to achieve the pressure swing effect, and the tail gas transmitted from the tail gas pipe is input into the main box through the setting of the intake pipe, and the comonomer and the induced condensing agent with larger molecules remaining in the tail gas after the treatment of the high and low pressure cooling condensation recovery unit can be better selectively adsorbed through the setting of the adsorption plate, and can be smoothly desorbed by reducing the pressure and evacuating in a short time, and the recovery tank is set , for further collection and post-processing, the threaded connection between the intake pipe and the tail pipe is convenient for the installation of the tail pipe, the cooperation between the fixing block and the fixing ring is convenient for the fixing of the recovery tank, and the disassembly is convenient for the removal and replacement of the recovery tank. The mortise and tenon connection between the bottom plate attachment plate and the mounting plate, and the threaded cooperation between the bolts and the mounting grooves are convenient for the fixation of the adsorption plate. By removing the bolts, it is convenient to pull out the adsorption plate for replacement and reuse. The utility model can selectively adsorb the comonomers and induced condensing agents with larger molecules remaining in the tail gas treated by the high and low pressure cooling condensation recovery unit, and can be smoothly desorbed by reducing the pressure and evacuating in a short time, and is easy to disassemble and replace, with a small size, which is convenient for small-scale treatment.

[0004] According to the above patent, there is currently no pressure swing adsorption separation and concentration unit that is small in size and used for small-scale processing, which is convenient for replacing adsorbents and is convenient for recovering the exhaust gas of polyethylene devices after coarse and fine filtration and pre-purification. However, the device is fixed by bolts, which is not convenient for subsequent replacement of the adsorption plate. The parts fixed by bolts are prone to rust after long-term use, which will affect the device. Utility Model Content
