System of lowering content of waste gas in solution polymerization rubber process

Abstract

The invention discloses a system of lowering content of waste gas in a solution polymerization rubber process. The system comprises a steam ejecting vacuumizer, a slurry tank, a condensation tower, a condenser and an oil-water separation tank, the steam ejecting vacuumizer is mounted at the top of the slurry tank, an outlet pipeline of the steam ejecting vacuumizer is connected with the bottom of the condensation tower, a gas outlet at the top of the condensation tower is connected with the condenser, an outlet of the condenser is connected with the oil-water separation tank, an inlet of the steam ejecting vacuumizer is connected with a driving steam inlet pipeline which is provided with a pressure adjusting valve, and an outlet pipeline of the steam ejecting vacuumizer is provided with a pressure transmitter which is electrically connected with the pressure adjusting valve. The system is simple in structure: the slurry tank is introduced into the steam ejecting vacuumizer to recycle solvent steam of the slurry tank, non-methane total hydrocarbon quantity discharged into glue of a subsequent treatment device is lowered, non-methane total hydrocarbon can be collected through a gas collection cover and directly discharged through an exhaust barrel, and requirements of environment-protection discharging standards can be met; the recycled solvent steam can be delivered to the condensation tower, so that steam recycling is realized.

Description

technical field [0001] The invention relates to a synthetic rubber technology, in particular to a system for reducing the content of non-methane total hydrocarbon waste gas in the solution polymerization rubber process. Background technique [0002] The solution polymerization rubber process is a process in which monomers and initiators (catalysts) are dissolved in appropriate solvents for polymerization. The solvent is generally an organic solvent, depending on the nature of the monomer, the initiator (or catalyst) and the resulting polymer. The latex after solution polymerization generally needs to be flashed, concentrated, and coagulated, and then sent to a subsequent processing device (vibrating screen, dehydrator, dryer, etc.) for processing, and finally packaged to obtain a finished product. [0003] At present, for the treatment of the non-methane total hydrocarbon waste gas generated by the follow-up treatment device, terminal treatment is mostly used: the non-metha...
