After sealing, the negative pressure motor is used for blowing negative pressure air flow into the elastic tube 14, so that the negative pressure air flow sucks exhaust gas discharged from the vulcanizing furnace into the collecting bin 28, the exhaust gas discharged from the vulcanizing furnace during working can not be emitted indoors, the health of staff is endangered, the sealing cover 12 is used for heat insulation and sealing, and the exhaust gas is sucked into the collecting bin 28 through the blower.
(3) Decomposing the harmful gas xylene.
Firstly, injecting 25-40 mL of absolute ethyl alcohol into a collection bin 28;
injecting secondary distilled water into the collection bin 28 to prepare 250-265 mL mixed solution;
adding 50g zeolite to collection bin 28;
after 30min of the start of the ultrasonic wave, the xylenes were degraded into CO2 and H2O and mixed in the solution.
The ultrasonic frequency is 20KHZ, the sound intensity is 141.32W/cm < 2 >, the dimethylbenzene discharged by the vulcanizing furnace can be obtained and degraded into pollution-free CO2 and H2O, and the CO2 and the H2O are soluble in water, so that the collecting and the discharging of the dimethylbenzene are also facilitated.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
