But liquid, with the external pipeline 33 being connected to inside cooling chamber 1, the circulating pump 51 and refrigeration machine 52 being connected on external pipeline 33.Institute
Stating coolant liquid is water, and under the action of circulating pump 51 and refrigeration machine 52, coolant liquid recycles between cooling chamber 1 and external pipeline 33
It flows and keeps lower temperature, to reduce the temperature of exhaust gas.
It further include the exhaust piping 32 in cooling chamber 1, the exhaust gas being connected to exhaust piping 32 enters pipeline 31 and gives up
Gas discharge line 34.Exhaust gas enters pipeline 31 by exhaust gas and enters in exhaust piping 32, then is discharged by exhaust emission tube road 34.It is described
Exhaust piping 32 is made of ceramic materials, and the exhaust piping 32 is twist arranged, thus increase exhaust piping 32 with it is cold
But the contact area of liquid, quickly reduces exhaust gas temperature.
It further include the filter chamber 2 for being connected to 34 other end of exhaust emission tube road, two filter layers 8 in filter chamber 2.
The filter layer 8 improves the filter efficiency of exhaust gas to increase the contact area of exhaust gas Yu filter layer 8 in back taper.Institute
State filter layer 8 include lower bracing frame 82, upper support frame 81, the active carbon 83 between upper support frame 81 and lower support bar 82, from
And the organic solvent in adsorbable exhaust gas, the gas for making exhaust gas become room temperature cleaning are discharged.
It further include the first solenoid valve 41 for being mounted on exhaust gas and entering on pipeline 31, be mounted on exhaust emission tube road 34
Two solenoid valves 42 and temperature sensor 6, the single-chip microcontroller being connect with the first solenoid valve 41, second solenoid valve 42 and temperature sensor 6
(not shown).Second solenoid valve 42 is arranged close to 2 entrance of filter chamber, and temperature sensor 6 is located at 42 front of second solenoid valve.Temperature
