[0014] Working principle: When the whole equipment is in use, the centrifugal fan of the circulation mechanism draws the air in the cargo shower room or the exhaust channel of the air shower room and injects it into the upper and middle part of the inner side of the treatment box of the treatment mechanism through the connecting pipe. At the same time, the spray row sprays the input air to absorb the floating objects and dust in the air. After the spraying treatment, the water enters the inner flow groove at the corresponding position through the opening on the partition plate 1. Then, the water in the inner flow groove is diverted again through the diversion groove and flows into the water storage cavity. At this time, the treated air enters the inner cavity 1 of the installation box through the connecting pipe. Then, the output shaft of the stepper motor on the installation plate rotates to drive the rotating shaft in the installation box to rotate. At the same time, the rotating shaft rotates When the air reaches the position of the inner chamber 2, the circulation pump 2 draws the water in the water storage chamber into the position of the inner chamber 2 through the connecting pipe, and the water in the water storage chamber is pumped while the dust and impurities in the water are adsorbed and filtered through the filter cotton plate. When the water in the water storage chamber reaches the position of the inner chamber 2, it mixes with the air, and at the same time, sodium hydroxide is injected into the position of the inner chamber 2 through the automatic injector 2 to form a sodium hydroxide solution. The sodium hydroxide solution reacts with harmful substances such as sulfur dioxide in the exhaust gas of the air to generate sodium sulfite and sodium nitrite. After the reaction is completed, After completion, the output shaft of the stepper motor continues to drive the rotating shaft and the partition plate 2 to continue rotating, so that the solution originally in the inner cavity 2 rotates to the position of the inner cavity 3. At this time, the automatic injector 1 injects calcium chloride medicine into the solution at the position of the inner cavity 3. After the calcium chloride medicine is added to the solution, the sodium sulfite and sodium nitrite harmful substances generated by the previous reaction are neutralized to generate calcium sulfite, and the impurities in the water are purified by the generated calcium sulfite to become ordinary water. After purification, the output shaft of the stepper motor continues to drive the rotating shaft and the partition plate 2 to continue rotating, so that the water originally at the position of the inner cavity 3 rotates to the position of the inner cavity 4. At this time, the circulating pump 2 pumps the water in the inner cavity 4 through the connecting pipe and supplies it to the spray row for use , thereby making the interior of the inner cavity four a vacuum state, and then the output shaft of the stepper motor continues to drive the rotating shaft and the partition plate 2 to continue rotating, so that the vacuum chamber originally at the position of the inner cavity four first rotates to the position of the inner cavity five and then rotates to the position of the inner cavity six. When it rotates to the position of the inner cavity six, the air in the external environment is filtered by the filter cover and enters the position of the inner cavity six through the air inlet pipe. At the same time, the centrifugal fan 2 pumps the inner middle and lower chamber of the processing box through the connecting pipe. The external air at the position of the inner cavity six enters the inner middle and lower part of the processing box through the connecting pipe, and is sprayed and purified by the water flowing out of the diverter groove at the bottom of the partition plate 1, and then discharged into the ventilation channel.

[0015] The present invention provides an air circulation purification device having the following beneficial effects:

[0016] 1. The present invention circulates and purifies the air in the cargo shower room and the air shower room through a circulation purification method. During the purification process, dust and impurities in the air are first filtered out by a water curtain dust filter, and then harmful substances in the air exhaust are neutralized by a chemical reaction to generate calcium sulfite that can purify water, thereby reducing the degree of pollution to the surrounding environment caused by air emissions from the cargo shower room and the air shower room.

[0017] 2. In the process of purifying the air in the cargo shower room and the air shower room, the present invention reduces the use of water resources in purifying the air in the cargo shower room and the air shower room by recycling water, and also improves the utilization rate of water resources in the purification equipment.

[0018] 3. The present invention not only circulates and purifies the air discharged from the cargo shower room and the air shower room, but also introduces the air from the external environment into the cargo shower room and the air shower room after multiple filtration and purification, thereby improving the speed of air circulation in the cargo shower room and the air shower room and ensuring the freshness of the air in the cargo shower room and the air shower room.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1:

[0029] Please see the attached Figure 1 - Attachment Figure 4 , an embodiment of the present invention provides an air circulation purification device, comprising a wall 1, a circulation mechanism 2 is provided in the middle of one front side of the wall 1, a processing mechanism 3 is provided in the middle of the front side of the wall 1, and a purification mechanism 5 is provided in the middle of the other front side of the wall 1;

[0030] The purification mechanism 5 includes an installation box 501, and automatic injector 2 505 and automatic injector 1 504 are respectively provided on both sides of the upper and middle parts of the front end of the installation box 501. The middle part of the inner side of the installation box 501 is rotatably connected to the rotating shaft 510, and six partition plates 2 513 are equidistantly provided on the outer wall of the rotating shaft 510. The partition plates 2 513 divide the inner cavity of the installation box 501 into six chambers, namely, inner cavity 1 506, inner cavity 2 507, inner cavity 3 508, inner cavity 4 509, inner cavity 511 and inner cavity 6 512 in sequence. The middle part of the outer side of the front end of the installation box 501 is fixedly connected to the installation plate 502, and the middle part of the top end of the installation plate 502 is fixedly connected to the stepping motor 503, and the output shaft of the stepping motor 503 passes through the installation box 501 and is fixedly connected to the middle part of the rotating shaft 510.

[0031] The upper middle portion of the side of the processing box 301 away from the circulation mechanism 2 is connected to the inner cavity 1 506 in the installation box 501 through a connecting pipe, and the lower middle portion of the side of the processing box 301 away from the circulation mechanism 2 is connected to the inner cavity 6 512 in the installation box 501 through a connecting pipe.

[0032] The air inlet of centrifugal fan 1 201 is connected to the interior of the exhaust channel on the wall 1, the exhaust port of centrifugal fan 2 202 is connected to the interior of the ventilation channel on the wall 1, the interior of inner cavity 6 512 is connected to one end of the air inlet pipe 4, and a filter cover 6 is threadedly connected to the end of the air inlet pipe 4 away from the installation box 501.

[0033] The integral installation box 501 is divided into six chambers by the partition plate 2 513 on the rotating shaft 510. The stepping motor 503 drives the rotating shaft 510 and the partition plate 2 513 thereon to rotate synchronously, and the gas and liquid between the partition plate 2 513 are synchronously changed in position, and then processed in accordance with different processing methods. In addition, the wheel-type circulation processing method can also improve the air circulation processing speed in the cargo shower room or air shower room.

[0034] When circulating and purifying air, the first step is: the air processed by the circulation mechanism 2 enters the inner cavity 1 506 of the installation box 501 through the connecting pipe, and then the output shaft of the stepping motor 503 on the installation plate 502 rotates to drive the rotating shaft 510 in the installation box 501 to rotate. The rotating shaft 510 rotates and drives the partition plate 2 513 to rotate synchronously, so that the air in the inner cavity 1 506 is rotated to the position of the original inner cavity 2 507, and the other inner cavities rotate synchronously.

[0035] Step 2: When the air reaches the position of the second inner cavity 507, the circulation pump 1 302 draws the water in the water storage chamber 308 into the position of the second inner cavity 507 through the connecting pipe, and while the water in the water storage chamber 308 is being pumped, the dust and impurities in the water are adsorbed and filtered through the filter cotton plate 307. When the water in the water storage chamber 308 reaches the position of the second inner cavity 507, it mixes with the air, and at the same time, sodium hydroxide is injected into the position of the second inner cavity 507 through the automatic injector 2 505 to form a sodium hydroxide solution. The sodium hydroxide solution reacts with harmful substances such as sulfur dioxide, nitric oxide, and nitrogen dioxide in the exhaust gas, wherein sulfur dioxide reacts to form sodium sulfite, nitric oxide reacts to form sodium nitrite, and nitrogen dioxide reacts to form sodium nitrate, sodium nitrite, and water.

[0036] The harmful substances in the tail gas are mainly composed of SO2, NO and NO2, so in this application, sodium hydroxide is used to react with them. The chemical reaction formula during the treatment process is as follows:

[0037] SO2+2NAOH→NA2SO3+H2O

[0038] 2NO+O2→2NO2

[0039] 2NO2+2NAOH→NANO3+NANO2+H2O

[0040] Among them, SO2, NO and NO2 are the main acidic substances in the exhaust gas, and NAOH is an alkaline substance for treating these substances. The above reaction formula describes the process of NAOH reacting with SO2 and NOx, and produces stable alkaline products such as NA2SO 3、 NANO2 and NANO3 neutralize the harmful substances in the exhaust gas through this neutralization reaction, thereby achieving the effect of purifying the harmful substances in the exhaust gas.

[0041] Step 3: After the reaction process at the position of the second inner cavity 507 is completed, the output shaft of the stepping motor 503 continues to drive the rotating shaft 510 and the second partition plate 513 to continue to rotate, so that the solution originally in the second inner cavity 507 rotates to the position of the third inner cavity 508. At this time, the automatic injector 1 504 injects calcium chloride into the solution at the position of the third inner cavity 508. After the calcium chloride is added to the solution, sodium sulfite reacts with calcium chloride to form calcium sulfite, and sodium nitrite reacts with calcium chloride to form calcium nitrite. The generated calcium sulfite purifies impurities in the water and turns it into ordinary water.

[0042] After the third step of neutralization of the tail gas, NA2SO3 is generated and reacts with calcium chloride again. The specific chemical reaction equation is as follows:

[0043] Na2SO3+CaCl2→CaSO3↓+2NaCl

[0044] Wherein, when the reaction is carried out in this step, sodium sulfite reacts with calcium chloride to generate calcium sulfite, and the calcium sulfite can be used to purify water.

[0045] Step 4: After the reflection process at the position of the third inner chamber 508 is completed, the output shaft of the stepper motor 503 continues to drive the rotating shaft 510 and the second partition plate 513 to continue to rotate, so that the water originally at the position of the third inner chamber 508 is moved to the position of the fourth inner chamber 509. At this time, the second circulation pump 303 pumps the water in the fourth inner chamber 509 through the connecting pipe and supplies it to the spray row 304 for use, thereby creating a vacuum state inside the fourth inner chamber 509.

[0046] Step 5: After the fourth inner chamber 509 is in a vacuum state, the output shaft of the stepper motor 503 continues to drive the rotating shaft 510 and the second partition plate 513 to rotate, causing the vacuum chamber originally located at the fourth inner chamber 509 to first rotate to the fifth inner chamber 511 and then to the sixth inner chamber 512. When the vacuum chamber reaches the sixth inner chamber 512, air from the external environment is filtered by the filter cover 6 and then enters the sixth inner chamber 512 through the air inlet pipe 4.

[0047] Step 6: When the air in the external environment enters the position of the inner cavity six 512 through the air inlet pipe 4, the centrifugal fan two 202 draws the air into the inner middle and lower chamber of the processing box 301 through the connecting pipe, and the external air at the position of the inner cavity six 512 enters the inner middle and lower part of the processing box 301 through the connecting pipe, and is sprayed and purified by the water flowing out of the diverter groove 310 at the bottom of the partition plate one 305, and then discharged into the ventilation channel, so that the air in the external environment is returned to the cargo shower room and the air shower room after being purified.

[0051] The processing mechanism 3 is divided into two upper and lower processing chambers. The upper chamber is used to spray and reduce dust on the air discharged from the room, and the lower chamber is used to spray and reduce dust on the air circulated from the outside. The lower chamber also has a water storage chamber 308 and a filter cotton plate 307 inside it.
