1. In view of the problem of dust, moisture and a small amount of oil mixed in the waste gas generated by the internal mixer in the rubber mixing workshop, a pretreatment module is designed in the main waste gas treatment equipment to pretreat the waste gas and remove the dust, moisture and oil substances carried in the waste gas. The exhaust funnel is marked Y1-Y7.
Description of rubber refining waste gas treatment process:
(1) Waste gas from the rubber mixing workshop is collected through pipes and filtered before entering the treatment equipment to prevent large particles from entering the treatment equipment and causing impact on the equipment.
(2) After the waste gas enters the treatment equipment, it first passes through the pretreatment module. In view of the characteristics of the waste gas generated in the rubber mixing workshop, the pretreatment module adopts a separation plate structure to remove the dust, moisture and a small amount of oil substances mixed in the waste gas.
(3) After being treated by the pretreatment module, the waste gas enters the core treatment area of the equipment, namely the treatment area of "membrane deodorization+photocatalysis+activated carbon fiber adsorption". In this area, the waste gas molecules first pass through the deodorization membrane module, and the odor macromolecules in the waste gas are absorbed by the efficient fiber membrane.
(4) The waste gas then enters the photocatalysis module, which is equipped with a specially made high-intensity UV lamp tube. The odor molecules are directly activated by light irradiation for decomposition, and the odor molecules are indirectly decomposed by light irradiation to activate other gas molecules, so as to remove the odor molecules in the waste gas and effectively purify the odor gases.
(5) The waste gas after photocatalysis treatment finally passes through the activated carbon fiber module, and the ACF activated carbon fiber is used to adsorb the remaining odor molecules in the waste gas, so as to completely purify the waste gas.
