Further, the deduster left is connected with several groups gas gathering mask by gas-guide pipeline, and deduster selects arteries and veins
Deduster is rushed, by several groups gas gathering mask, the flue gas generated in waste and old ABS plastic regenerative process is directed into deduster.
Further, it is described except VOCs component include low-temperature plasma device and by gas-guide pipeline be connected to low temperature etc. from
The photooxidation decomposer of sub- device right, by connecting on the right side of gas-guide pipeline and electric coke catcher, photooxidation is decomposed in low-temperature plasma device left side
By being connect on the upside of gas-guide pipeline and blower on the right side of device, by low-temperature plasma device and photooxidation decomposer, so that VOCs is resolved into
Low molecular compound, water and carbon dioxide realize that the elimination of VOCs is decomposed.
Further, tourie inner cavity upper layer is provided with polypropylene demisting layer, when flue gas passes through absorption chamber interior suction
After receiving liquid purification, purified gas contains a small amount of moisture, and purified gas can occur with the filament in polypropylene demisting layer
Collision, so that a small amount of moisture can be adhered to blanking by filament, purified gas will continue to rise, subsequent to contain the net of a small amount of moisture
Gas continues through polypropylene demisting layer after change, and a small amount of moisture continuation is collided with filament, can glue at this time with previous
The moisture being attached on filament occurs cohesion and forms water droplet, and finally falls under the effect of gravity, to realize to purified gas
Body carries out removing moisture, avoids moisture interference electric coke catcher to oil removing effect of purified gas.
Further, two groups of stirring motors are provided with by support frame in the middle part of the tourie inner cavity, under stirring motor
Side output shaft is provided with agitating paddle, and agitating paddle is separately positioned in absorption chamber, by being stirred in absorption chamber, to mention
