[0040] Reference Figure 1 and Figure 2 During the cardboard production process, the gas discharged during the production process is recovered through the recovery pipe 2. The recovered gas is then fed into the water within the primary filter cylinder 15 through the gas pipe 181 and the diverter 182.

The diverter 182 helps to disperse the recovered gas sent into the water, breaking the gas into multiple small bubbles. This helps to increase the contact area between the recovered gas and the water, thereby improving the water's filtering effect on fine debris in the recovered gas.

When the recycled gas passes through the filter screen cartridge 20, the filter screen cartridge 20 helps to intercept and filter the debris remaining in the recycled gas after the initial filtration, thereby facilitating the secondary filtration of the recycled gas and further helping to improve the cleanliness of the recycled gas.

[0048] Reference Figure 1 When the recycled gas stored in gas tank 54 is used, outlet valve 62 is opened, allowing the recycled gas in gas tank 54 to be discharged through outlet pipe 61. As the discharged gas passes through pressure reducing valve 63, pressure reducing valve 63 regulates the pressure of the discharged gas, thereby ensuring the subsequent use of the discharged gas.

[0051] Reference Figure 5 and Figure 6 When the output gas in the outlet pipe 61 enters the inner diversion outer cylinder 71, it flows along the multiple diversion channels 9. Simultaneously, external cooling water enters the main water inlet hole 11 through the water inlet pipe 81, and then flows into the multiple diversion channels 10 through the multiple water inlet branch holes 12. The diversion channels 10 extend the cooling water's flow path within the diversion inner cylinder 72 and accelerate its flow rate within the diversion inner cylinder 72, thereby facilitating the cooling of the output gas with the cooling water and improving its subsequent use in the cardboard cooling process.

[0052] The implementation principle of the embodiment of the present application is as follows: during the production process of cardboard, the gas discharged during the production process is recovered through the recovery pipe 2, and the recovered gas is sent into the water body in the preliminary filter cylinder 15 through the gas supply pipe 181 and the diverter 182; when the recovered gas passes through the water body, the recovered gas comes into contact with the water body, which helps to filter the tiny debris in the recovered gas through the water body, thereby helping to improve the cleanliness of the recovered gas.

[0053] After the recycled gas is initially filtered, it enters the interior of the secondary filter cylinder 17 through the connecting pipe 16, and after passing through the filter screen cartridge 20, it enters the interior of the mounting base 19, and then enters the interior of the storage box 4 through the connecting pipe 3. When the recycled gas passes through the filter screen cartridge 20, the filter screen cartridge 20 helps to intercept and filter the debris remaining in the recycled gas after the initial filtration, thereby facilitating the secondary filtration of the recycled gas and further helping to improve the cleanliness of the recycled gas.

[0054] After the recycled gas is filtered, it enters the air inlet pipe 51 through the connecting pipe 3.
