[0002] The composition of waste gas generated during the plastic pellet modification process varies depending on the type of plastic, modification process, and additives. The plastic pellet modification process generally produces volatile organic compounds, toxic gases, particulate matter, acidic gases, smoke, smoke, and malodorous gases. To treat these waste gases, appropriate waste gas treatment systems, such as activated carbon adsorption, wet scrubbing, and catalytic combustion, are usually required to reduce environmental pollution and protect worker health. Wet scrubbing is a commonly used waste gas treatment method, primarily involving contact between a liquid (usually water or a chemical solution) and pollutants in the waste gas to absorb or neutralize harmful gases and particulate matter. Equipment used for wet scrubbing is typically referred to as a wet scrubber or spray tower.

[0003] However, in existing spray towers, the packing layer is generally set as a block or plate structure made of plastic rings, ceramic fillers or other inert materials with a high specific surface area, and supported by a support grid. This type of packing layer and support grid are not conducive to the circulation of exhaust gas inside the tower body, thereby affecting the exhaust gas treatment efficiency to a certain extent.

[0030] See also Figures 1 to 4 The present invention discloses a device for treating waste gas from plastic modification, which includes a tower body 100, a spray assembly 200, and a filler assembly 300. The spray assembly 200 and the filler assembly 300 are both disposed in the tower body 100, wherein the filler assembly 300 is disposed inside the tower body 100 and extends a preset distance from one end of the tower body 100 to the other end along the length direction of the tower body 100. The spray assembly 200 is disposed on a side wall surface at the top of the tower body 100, and the output end of the spray assembly 200 is disposed toward the filler assembly 300. Specifically, the tower body 100 is provided with an air intake pipe a, an exhaust pipe b, and a liquid discharge pipe. The air intake pipe a is disposed on the side wall surface at the bottom of the tower body 100 and connects the inside and outside of the tower body 100; the liquid discharge pipe is disposed at the top of the tower body 100 and connects the inside and outside of the tower body 100; and the liquid discharge pipe is disposed at the bottom end of the tower body 100 and connects the inside and outside of the tower body 100. In actual application, the exhaust gas enters the tower body 100 through the air inlet pipe a, and the exhaust gas rises along the length direction of the tower body 100 toward the exhaust pipe b at the top. In this process, the filler assembly 300 hinders the exhaust gas from rising, while the spray assembly 200 sprays the scrubbing liquid on the surface of the filler assembly 300, thereby greatly increasing the contact area and contact time between the scrubbing liquid and the exhaust gas, so that the scrubbing liquid can fully clean the exhaust gas, so as to promote the dissolution of soluble components in the exhaust gas in the scrubbing liquid, thereby realizing the separation of harmful soluble substances in the exhaust gas. By adaptively adjusting the scrubbing liquid, the exhaust gas can be targeted and cleaned according to actual needs, so that the air flow output from the exhaust pipe b meets the emission standard, thereby completing the treatment and discharge of the plastic modification waste gas, wherein the scrubbing liquid that completes the scrubbing work is discharged through the drain pipe at the bottom of the tower body 100 for recycling and reuse.

[0031] Furthermore, the packing assembly 300 includes a plurality of packing columns 310 and a packing mounting plate 320. The packing mounting plate is disposed at the top of the tower body 100, and the plurality of packing columns 310 are connected to the packing mounting plate 320, thereby enabling the plurality of packing columns 310 to be stably mounted within the tower body 100. Specifically, each packing column 310 extends a predetermined distance from the packing mounting plate 320 toward the bottom of the tower body 100 along the length of the tower body 100. This ensures that the exhaust gas, while flowing within the tower body 100, comes into contact with the surface of each packing column 310 at a sufficient distance. This allows the exhaust gas to fully interact with the scrubbing liquid on the surface of the packing columns 310, thereby improving the scrubbing effect of the scrubbing liquid on the exhaust gas.

[0032] Furthermore, the spray assembly 200 includes a sprayer 210 and a spray pipe 220. One end of the spray pipe 220 is arranged on the outer surface of the top side wall of the tower body 100 and is connected to the interior of the tower body 100; the sprayer 210 is arranged at the other end of the spray pipe 220, and the output end of the sprayer 210 is connected to the interior of the tower body 100 through the spray pipe 220, so that the sprayer 210 can spray the scrubbing liquid into the interior of the tower body 100.

[0033] Furthermore, the tower body 100 comprises a main body 110 and a tower cover 120. The tower cover 120 snaps onto the top of the main body 110, forming a relatively closed cavity. Specifically, the filler assembly 300 is housed within the main body 110, and the spray assembly 200 is mounted on the tower cover 120. The air intake pipe a and the liquid discharge pipe are respectively installed at the bottom of the main body 110, and the exhaust pipe b is installed at the top of the tower cover 120. In actual use, the tower cover 120 is designed to be removable between the main body 110 to facilitate daily use, maintenance, and repair.

[0034] Furthermore, the exhaust duct b is provided with a cover plate b1 and a drive unit b2. The cover plate b1 is hinged to the pipe mouth of the exhaust duct b. The drive unit b2 drives the hinge shaft connected between the cover plate b1 and the exhaust duct b, so that the drive unit b2 can drive the cover plate b1 to open and close relative to the exhaust duct b.

[0035] Furthermore, two air intake pipes a are provided, and the two air intake pipes a are respectively provided on the two side walls of the bottom of the main body 110, so that the exhaust gas can enter the interior of the main body 110 from both sides of the bottom of the main body 110, thereby ensuring the uniformity of the exhaust gas inside the main body 110 to a certain extent.

[0036] Furthermore, a liquid guide plate 111 is provided on the bottom side of the main body 110. The liquid guide plate 111 is deflected at a preset angle relative to the length of the main body 110, so that the scrubbing liquid can converge at the bottom end of the liquid guide plate 111. Specifically, the drainage pipe includes two first drainage pipes c and a second drainage pipe d. The two first drainage pipes c are provided on the liquid guide plate 111 and respectively connect to the interior of the main body 110. The second drainage pipe d is provided at the bottom end of the main body 110 corresponding to the liquid guide plate 111. In actual use, when the scrubbing liquid passes through the liquid guide plate 111, the scrubbing liquid flows out through the two first drainage pipes c; when the scrubbing liquid flows to the bottom end of the liquid guide plate 111, the scrubbing liquid flows out through the second drainage pipe d.

[0037] To sum up, the plastic modification waste gas treatment device disclosed by the present invention sprays the scrubbing liquid on the surface of the packing component through the spray component. The packing component extends a preset distance from one end of the tower body to the other end along the length direction of the tower body. The spray component is arranged on one side wall of the top of the tower body, and the output end of the spray component is arranged toward the packing component, so that the contact area and contact time between the scrubbing liquid and the waste gas can be greatly increased while ensuring the fluidity of the waste gas inside the tower body, so that the scrubbing liquid can fully clean the waste gas to promote the dissolution of the soluble components in the waste gas in the scrubbing liquid, thereby realizing efficient separation of harmful soluble substances in the waste gas. By adaptively adjusting the scrubbing liquid, the waste gas can be targeted and cleaned according to actual needs, so that the airflow output from the exhaust pipe reaches the emission standard, thereby completing the treatment and discharge of the plastic modification waste gas, wherein the scrubbing liquid that has completed the scrubbing work is discharged through the drain pipe at the bottom of the tower body for recycling and reuse.
