The temperature reaches 20'C, and the temperature is 8 at the 0 point at the entrance of the direct pull dust collector bag room 14.
The temperature drops to 0℃. Such a spray cooling tower 16.1
By cooling the exhaust gas in step 8, the oil mist and organic solvent in the exhaust gas condense into droplets, some of which are washed with spray water along with dust and foreign matter and accumulate at the bottom of the spray cooling tower 16.18. Drain 16c, 1
Taken from 8G. The droplet-shaped oil components and organic solvent components that were not removed by the spray cooling tower 16 and 18 flow together with the exhaust gas flow to the adsorbent supply device 20, where they are dropped from the adsorbent supply device 20. The adsorbent is adsorbed by a large number of granular adsorbents 26 that are supplied to the adsorbent, and is taken out from the adsorbent receiver 24.
