[0039] Combine the following Figure 1-Figure 11 The purification system for producing and processing a degradable film of the present invention is described, comprising: a purification box 100, an air pump 200 is installed at the upper end of the purification box 100, and the air inlet end of the air pump 200 is connected to the upper end of the purification box 100; a purification mechanism 300, the purification mechanism 300 is installed inside the purification box 100, the lower end of the purification mechanism 300 penetrates to the bottom of the purification box 100, and the surface of the purification mechanism 300 extends to the outside of the purification box 100; wherein the purification mechanism 300 includes a positioning frame 330 fixedly connected to the surface of the purification box 100, a mixing purification component 310 is installed on the surface of the positioning frame 330, and an air injection pipe 340 is provided on the surface of the mixing purification component 310, and a delayed purification component 320 is connected to the lower end of the air injection pipe 340, and the delayed purification component 320 is arranged at the bottom of the purification box 100, and the upper end of the delayed purification component 320 extends to the inner top wall of the purification box 100;

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 As shown, the hybrid purification component 310 includes a lower cylinder body 311 fixedly connected to the upper end of the positioning frame 330, the upper end of the lower cylinder body 311 is fixedly connected to the upper cylinder body 312, the inner top wall of the upper cylinder body 312 is fixedly connected to the mounting frame 313, the inner wall of the mounting frame 313 is fixedly connected to the dual-axis motor 314, the upper end of the upper cylinder body 312 is fixedly connected to the low-pressure cabin 315 connected to the upper cylinder body 312, the upper end of the low-pressure cabin 315 is connected to the air duct 316, and the other end of the air duct 316 extends to the interior of the delayed purification component 320. The inner bottom wall of the lower cylinder 311 is fixedly connected with a connecting inner tube, the surface of the connecting inner tube is fixedly connected with a water-blocking film 3111, the outer edge of the water-blocking film 3111 contacts the inner wall of the lower cylinder 311, the lower end of the lower cylinder 311 is fixedly connected with a return pipe 3112 connected with the lower cylinder 311, and the other end of the return pipe 3112 passes through the upper end of the purification box 100 and extends to the interior of the delayed purification assembly 320;

[0041] The lower output shaft of the dual-axis motor 314 is fixedly connected to a water retaining plate 3144, the upper output shaft of the dual-axis motor 314 is fixedly connected to a fan impeller 3142, the outer sleeve of the water retaining plate 3144 is provided with a plurality of arc-shaped impellers 3143, the ends of the arc-shaped impellers 3143 are fixedly connected to a rotating ring 3141, the upper rotating ring 3141 is fixedly connected to the surface of the water retaining plate 3144, the interior of the lower cylinder 311 is fixedly connected to a vertical conduit 317, the positioning frame 330 is sleeved on the exterior of the vertical conduit 317, the surface of the vertical conduit 317 is connected to a capillary 3171, and the other end of the capillary 3171 is connected to the surface of the delayed purification component 320. The inner wall of the vertical conduit 317 is fixedly connected to an inner convex ring 3172, the inner side of the inner convex ring 3172 forms a narrow flow channel 3173, and the narrow flow channel 3173 is connected to the capillary 3171;

[0042] When the device is in use, the fan impeller 3142 and the water retaining plate 3144 are driven by the dual-axis motor 314 to rotate synchronously. When the fan impeller 3142 rotates, the gas inside the upper cylinder 312 can be guided to the inside of the low-pressure cabin 315. The upper cylinder 312 and the lower cylinder 311 form a sealed cavity. When the low-pressure cabin 315 rotates, a negative pressure is formed inside the cavity. Gas is injected into the gas injection pipe 340 to match the negative pressure, so that the air flow rate through the vertical duct 317 passes quickly.

[0043] At this time, the airflow that quickly passes through the vertical conduit 317 passes through the inner convex ring 3172. At this time, the flow cross section at the inner convex ring 3172 is reduced, and the cross section of the narrow flow channel 3173 forms an hourglass shape, so that the flow velocity of the airflow passing through this place is enhanced. At this time, the capillary 3171 is connected to the surface of the bottom liquid storage bin 321, and the cross section of the capillary 3171 is relatively smaller than the cross section of the bottom liquid storage bin 321. Since the airflow velocity at the upper end of the capillary 3171 is faster, the pressure at the upper end of the capillary 3171 is reduced. The entire surge must undergo the shrinking process of the narrow flow channel 3173 at the same time, so the pressure is also reduced at the same time, thereby generating a pressure difference. This pressure difference can provide an external suction force to the fluid inside the capillary 3171, so that the liquid inside the capillary 3171 is sucked into the narrow flow channel 3173. At this time, the exhaust gas and the liquid are mixed, so that the particles inside the exhaust gas are in contact with the liquid, reducing the situation where the exhaust gas particles easily flow with the airflow, and the exhaust gas can be initially cooled;

[0044] After that, the mixed gas enters the inner side of the arc-shaped impeller 3143. The rotation of the arc-shaped impeller 3143 causes the liquid in the mixed gas to be thrown to the inner wall of the upper cylinder 312. Under the action of gravity, the liquid slides to the inner bottom wall of the lower cylinder 311. Since the liquid is mixed and contacted with the particles in the exhaust gas, a preliminary purification effect is formed on the exhaust gas at this time, reducing the particles in the lung gas and preliminarily cooling the exhaust gas. The preliminarily filtered exhaust gas is guided to the bottom of the arc-shaped cover 3281 through the air guide pipe 316; the liquid inside the lower cylinder 311 gradually penetrates to the bottom of the water-retaining film 3111 and is guided to the inside of the vertical duct 317 through the reflux pipe 3112.

[0045] like Figure 1 , Figure 2 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, the delayed purification component 320 includes a bottom liquid storage bin 321 fixedly connected to the lower end of the purification box 100, a cooling bin 322 fixedly connected to the upper end of the bottom liquid storage bin 321, a middle axis 325 fixedly connected to the inner top wall of the cooling bin 322, a reflux spraying pool 327 fixedly connected to the surface of the middle axis 325 close to the inner top wall of the purification box 100, a plurality of spiral plates 326 fixedly connected to the surface of the middle axis 325 close to the bottom liquid storage bin 321, a fixing ring 328 is arranged below the spiral plate 326, and the fixing ring 328 is arranged inside the bottom liquid storage bin 321. The spiral plate 326 is fixedly connected to the inner wall of the cooling chamber 322 in a spiral shape, and a bottom guide plate 3261 is fixedly connected to the lower end of the spiral plate 326. An inner guide plate 3262 fixedly connected to the lower end of the spiral plate 326 is provided on the side of the bottom guide plate 3261 close to the middle shaft 325, and an outer guide plate 3263 fixedly connected to the lower end of the spiral plate 326 is provided on the side of the bottom guide plate 3261 away from the middle shaft 325.

[0046] A plurality of cooling plates 323 are fixedly connected to the surface of the cooling bin 322, and the cooling plates 323 are fixedly connected to the inner wall of the purification box 100. A low temperature tube 324 is sleeved on the outside of the cooling bin 322, and the low temperature tube 324 is embedded and installed on the surface of the cooling plate 323. A fixing ring 328 is fixedly connected to the lower end of the cooling plate 323, and an arc cover 3281 is fixedly connected to the inner wall of the fixing ring 328, and the arc cover 3281 is arc-shaped. A guide arc plate 3282 is fixedly connected to the surface of the fixing ring 328, and the guide arc plate 3282 is located between adjacent cooling plates 323;

[0047] When the device is in use, the gas is guided to the arc cover 3281 through the lower end of the air guide tube 316. Since the arc cover 3281 is in an upward convex arc shape, it temporarily retains the injected gas and prolongs the contact between the waste gas and the liquid. When the gas stored inside the arc cover 3281 fills the space below the arc cover 3281, the gas overflows the arc cover 3281 at this time. Under the action of buoyancy, the gas will rise to the bottom of the spiral plate 326. At this time, since the bottom guide plate 3261, the inner guide plate 3262 and the outer guide plate 3263 arranged below the spiral plate 326 are all provided with grooves, auxiliary guidance is formed for the gas, so that the gas gradually moves along the outer edge of the spiral plate 326, thereby increasing the path of the gas, so that the liquid fuses the impurities in the waste gas, reduces the emission of particulate matter in the waste gas, and increases the contact time between the gas and the liquid.

[0048] The liquid level in the cooling bin 322 is higher than the upper end of the spiral plate 326. When the gas floats above the liquid level, the liquid introduced by the reflux pipe 3112 flows into the interior of the vertical conduit 317. A plurality of through holes are provided at the lower end of the vertical conduit 317, which will cause the liquid to flow back into the cooling bin 322 again. In the process of lowering the water flow in the vertical conduit 317, the liquid will be filtered again with the exhaust gas, thereby improving the degree of purification of the exhaust gas.

[0049] When the device is in use, the dual-axis motor 314 is driven to drive the fan impeller 3142 and the water retaining plate 3144 to rotate accordingly. The fan impeller 3142 rotates to guide the gas inside the upper cylinder 312 to the inside of the low-pressure cabin 315, and the exhaust gas passes through the vertical duct 317 to accelerate the flow rate; the fluid inside the capillary 3171 is sucked outward, and the liquid inside the capillary 3171 is sucked into the narrow flow channel 3173, and the exhaust gas and the liquid are mixed. The exhaust gas and the liquid are mixed to initially cool the exhaust gas and enter the arc impeller 3143. The arc impeller 3143 rotates to swing the liquid in the mixed gas to the inner wall of the upper cylinder 312. Under the action of gravity, the liquid slides to the inner bottom wall of the lower cylinder 311, and the exhaust gas after preliminary filtration is guided to the bottom of the arc cover 3281 through the air guide pipe 316;

[0050] The gas is guided to the arc cover 3281 through the lower end of the air guide pipe 316. The arc cover 3281 is convex upward to temporarily retain the injected exhaust gas. The gas overflows the arc cover 3281 and rises to the spiral plate 326. The bottom guide plate 3261, the inner guide plate 3262 and the outer guide plate 3263 arranged below the spiral plate 326 are all provided with grooves to form auxiliary guidance for the gas. The gas moves along the outer edge of the spiral plate 326 to increase the gas path and contact time.

[0051] The liquid level inside the cooling bin 322 is higher than the upper end of the spiral plate 326. When the gas floats above the liquid level, the liquid inside the lower cylinder 311 gradually seeps under the water-blocking film 3111 and is guided to the inside of the vertical conduit 317 through the return pipe 3112. The liquid introduced by the return pipe 3112 flows into the inside of the vertical conduit 317. A plurality of through holes are provided at the lower end of the vertical conduit 317, so that the liquid can flow back to the inside of the cooling bin 322 again, and will be filtered again with the exhaust gas in the process of lowering the water flow in the vertical conduit 317, thereby improving the degree of purification of the exhaust gas.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
