[0037] Example 1

[0038] An energy-saving cleanroom control method includes the following steps:

[0039] S1. Gas Guidance: Guiding the exhaust gas from the cleanroom to the same channel for unified treatment;

[0040] S2. Harmful gas treatment: Eliminating harmful gases emitted from the cleanroom;

[0041] S3. Wastewater treatment: Dilute the wastewater to eliminate odors and discharge it intermittently.

[0042] like Figures 3-6 As shown, an energy-saving cleanroom includes a cleanroom 1 and a pre-filter 2; the pre-filter 2 is installed on the upper side of the cleanroom 1.

[0043] The nozzle 3 and the sponge 4 are further included; the clean room 1 is provided with a return air passage 1001 on the right side; at least four nozzles 3 are installed in the return air passage 1001; the sponge 4 is arranged below the nozzles 3; the clean room 1 is provided with a sewage outlet 1003; the sponge 4 is soaked by spraying water through the nozzles 3; when the harmful gases such as sulfur dioxide and chlorine gas remaining in the clean room 1 enter the return air passage 1001 through the sewage outlet 1003, the harmful gases move upward through the primary filter 2 on the upper side of the clean room 1, and the harmful gases soluble in water and the dust in the air are absorbed by the wet sponge 4, so as to reduce the accumulation of impurities on the primary filter 2, prevent the filter screen of the primary filter 2 from being overloaded, and greatly shorten the service life of the primary filter 2.

[0044] The support rod 103 and the support block 104 are further included; the support rod 103 is rotatably connected to the inner wall of the return air passage 1001; at least six support blocks 104 are fixedly connected to the support rod 103; the sponge 4 is driven to move up and down by the support rod 103, so as to absorb the harmful gases in the return air passage 1001 and adhere to the dust floating in the return air passage 1001, thereby reducing the accumulation of impurities on the primary filter 2.

[0045] The slide rail 101 and the electric sliding block 102 are further included; one slide rail 101 is fixedly connected to each side of the inner wall of the return air passage 1001; one electric sliding block 102 is slidably connected to each of the two slide rails 101, and the two electric sliding blocks 102 are fixedly connected to the support rod 103; the support rod 103 is driven to move up and down by the electric sliding block 102, thereby driving the sponge 4 to move up and down, so as to absorb the harmful gases in the return air passage 1001.

[0046] The harmful gas elimination process is described in detail as follows: harmful gases generated in the production process of the distillery are discharged from the clean room 1 through the fan filter unit on the upper side of the clean room 1, enter the drain pipe 1004 through the exhaust port 1003, and then enter the return air passage 1001. Since the harmful gases remaining in the clean room 1 are mostly sulfur dioxide, chlorine and sulfur dioxide, and the density of sulfur dioxide and chlorine is greater than that of air, and they are soluble in water, when the gases enter the return air passage 1001, the water jet 3 is controlled to spray water downward to wet the sponge 4. At the same time, the electric sliding block 102 drives the support rod 103 to move up and down, thereby driving the sponge 4 to move up and down, so that the harmful gases in the return air passage 1001 are absorbed by the sponge 4 to the greatest extent. At the same time, the filtered gases are mixed with fresh air in the return air passage 1001 and the fresh air passage 1002, filtered through the primary filter 2, and the dust and floating impurities in the return air passage 1001 are adsorbed on the sponge 4 due to the up-and-down movement of the sponge 4, thereby preventing the dust and impurities on the primary filter 2 from accumulating too much, causing the primary filter 2 to have too much load, affecting the service life of the primary filter 2, causing the intermediate filter and the high-level filter to have too much load, greatly shortening the service life of the intermediate filter and the high-level filter, and causing serious losses.

[0047] Example 2

[0048] Based on example 1, as shown in Figure 7 and Figure 8 , it further comprises a ring-shaped disperser 201, a fixed block 203 and a lead screw 204; the ring-shaped disperser 201 is fixedly connected to the inner wall of the return air passage 1001, and the ring-shaped disperser 201 is located between the sponge 4 and the water jet 3, and a plurality of holes are formed in the ring-shaped disperser 201; the water jetted by the water jet 3 falls on the sponge 4 along the holes due to the holes in the ring-shaped disperser 201, so that the sponge 4 is fully wetted and uniform, thereby making it easier for the harmful gases to be absorbed by the sponge 4; the fixed block 203 is fixedly connected to the inner wall of the return air passage 1001; the lead screw 204 is fixedly connected to the fixed block 203, and the support block 104 is rotationally connected to the lead screw 204; when the support block 104 moves up and down on the lead screw 204 and rotates at the same time driven by the electric sliding block 102, the sponge 4 also rotates, so that the sponge 4 generates a centrifugal force, and the water on the sponge 4 is thrown outward due to the centrifugal force.

[0049] The support block 104 is made of rubber, and the middle of the annular disperser 201 is provided with an opening, and the size of the opening is smaller than that of the sponge 4. When the sponge 4 moves upward through the opening of the annular disperser 201, the opening of the annular disperser 201 extrudes the sponge 4, thereby extruding the water saturated with a large amount of harmful gas in the sponge 4, facilitating subsequent water replenishment of the sponge 4, ensuring the subsequent elimination effect of the harmful gas. At the same time, the support block 104 drives the sponge 4 to move upward along the screw rod 204. Since the support block 104 is rotationally connected with the support rod 103, the support block 104 drives the sponge 4 to rotate when lifting the sponge 4 upward. During the rotation, centrifugal force is generated, so that the water on the sponge 4 is thrown outward along the centrifugal force, so that the water saturated in the sponge 4 is more easily separated from the sponge 4.

[0050] The extrusion block 202 is further included. At least eight extrusion blocks 202 are fixedly connected to the inner wall of the annular disperser 201. When the electric sliding block 102 drives the sponge 4 to move up and down, since the water in the sponge 4 has reached a saturated state by absorbing harmful gas and cannot continue to absorb harmful gas, after the sponge 4 moves upward to below the annular disperser 201, it continues to move upward and passes through the opening in the middle of the annular disperser 201. The extrusion blocks 202 on the annular disperser 201 and the opening extrude the sponge 4, thereby extruding the water in the sponge 4. Through repeated movement of the sponge 4 up and down, most of the water on the sponge 4 is extruded. Then, the nozzle 3 is controlled to spray water to continue to wet the sponge 4, thereby continuing to absorb harmful gas.

[0051] The extrusion block 202 is further included. At least eight extrusion blocks 202 are fixedly connected to the inner wall of the annular disperser 201. When the electric sliding block 102 drives the sponge 4 to move up and down, since the water in the sponge 4 has reached a saturated state by absorbing harmful gas and cannot continue to absorb harmful gas, after the sponge 4 moves upward to below the annular disperser 201, it continues to move upward and passes through the opening in the middle of the annular disperser 201. The extrusion blocks 202 on the annular disperser 201 and the opening extrude the sponge 4, thereby extruding the water in the sponge 4. Through repeated movement of the sponge 4 up and down, most of the water on the sponge 4 is extruded. Then, the nozzle 3 is controlled to spray water to continue to wet the sponge 4, thereby continuing to absorb harmful gas.

[0052] Embodiment 3

[0053] On the basis of embodiments 1-2, as Figures 9-11The cleaning assembly includes a water storage tank 301, an electric valve 302, an impeller 303 and a cleaning plate 304. The water storage tank 301 is fixed to the lower side of the return air channel 1001. The water storage tank 301 is in communication with the drain pipe 1004. The water storage tank 301 is used to store the water sprayed by the spray head 3 and the water squeezed by the sponge 4, dilutes the sewage discharged from the drain pipe 1004, weakens the odor in the return air channel 1001, dissolves the harmful gas discharged from the drain pipe 1004 in water, eliminates the harmful gas, and prevents the aggregation of sewage to breed microorganisms by interval drainage of the water storage tank 301. The electric valve 302 is installed on the right side of the water storage tank 301 and can move up and down. The impeller 303 is installed at the bottom of the water storage tank 301. The at least three cleaning plates 304 are fixed to the impeller 303. A plurality of holes are formed in the cleaning plate 304. The holes in the cleaning plate 304 reduce the water resistance in the rotating process, so that the rotating speed of the impeller 303 is faster, and the cleaning effect of the cleaning plate 304 on the dirt is improved. The water in the water storage tank 301 flows out of the drain outlet by moving the electric valve 302 up and down, the water flowing outwards drives the impeller 303 to rotate, and then drives the cleaning plate 304 to rotate, so as to clean the dirt at the bottom of the water storage tank 301.

[0054] The high-pressure igniter 401 is further included. The high-pressure igniter 401 is fixed to the end of the drain pipe 1004. The hydrogen sulfide gas discharged from the clean room 1 is burned by the high-pressure igniter 401. Part of the generated sulfur dioxide gas is deposited downwards due to the greater density than air and is dissolved in the water in the water storage tank 301. The other part is absorbed by the sponge 4 in the return air channel 1001 due to the upward movement of the primary filter 2, so as to eliminate the residual hydrogen sulfide gas.

[0055] The sewage discharge process is described in detail as follows. The sewage in the clean room 1 enters the drain pipe 1004 through the sewage discharge port 1003, and then is discharged into the water storage tank 301. The water sprayed by the spray head 3 continuously accumulates in the water storage tank 301. When the sewage is discharged from the drain pipe 1004 into the water storage tank 301, the water sprayed by the spray head 3 dilutes the sewage, effectively weakening the odor of the sewage. When the water amount in the water storage tank 301 reaches a set value, the electric valve 302 is controlled to move upwards to discharge water. The sewage is discharged from the drain outlet. The interval drainage effectively prevents the aggregation of sewage to breed microorganisms. Due to the impact of the water flow, the impeller 303 located at the drain outlet rotates under the impact of the water flow, and then drives the cleaning plate 304 to scrape off the dirt at the bottom of the water storage tank 301. Since a plurality of holes are formed in the cleaning plate 304, the water resistance in the rotating process of the cleaning plate 304 is effectively reduced, so that the impeller 303 is more likely to drive the cleaning plate 304 to rotate, and then the scraped dirt follows the water flow to the drain outlet and is finally discharged to the sewage treatment place.

[0056] Example 4

[0057] On the basis of Embodiment 1, as shown in Figure 1 、 Figure 2 and Figure 12 The activated carbon 501 is further included; the activated carbon 501 is fixed to the inner wall of the return air passage 1001 and is located above the nozzle 3; the activated carbon 501 eliminates the microorganisms carried by the upward moving gas in the return air passage 1001, thereby preventing the microorganisms from breeding on the primary filter 2, causing the primary filter 2 to be blocked, and further affecting the filtering effect, even damaging the primary filter 2, and causing resource waste.

[0058] The application is described in detail above, and the principle and implementation mode of the application are described by applying specific examples; the above embodiment description is only used to help understand the method and core idea of the application; meanwhile, for those skilled in the art, the specific implementation mode and application range will be changed according to the idea of the application; in summary, the content of the specification should not be understood as a limitation of the application.
