Description

TECHNICAL FIELD

[0001] The present application relates to the field of sterilization equipment, in particular to BC30 sterilization equipment and method thereof. BACKGROUND

[0002] In public places, part of the space is easy to cause pathogenic microorganisms (such as bacterial spores) to breed and spread, and the disinfection demand is urgent. In the prior art, formaldehyde fumigation and other methods have the problems of high toxicity and complex operation. Although chlorine dioxide is recognized as a high-efficiency and broad-spectrum disinfectant, its application in central air conditioning systems still has deficiencies. The current solutions focus on complex online generation and gasification systems, and the equipment investment and maintenance cost is high. In addition, there is a lack of simple and reproducible operation procedures for precise control of disinfection concentration, uniform distribution in complex air ducts, and standardization verification of final effect. Therefore, a chlorine dioxide disinfection method with controllable cost, standardized operation and verifiable effect is needed to solve the above problems in the prior art. SUMMARY

[0003] The purpose of the present application is to solve the problems existing in the prior art, and to provide a BC30 sterilization equipment and method thereof.

[0004] In a first aspect, the present application provides a BC sterilization equipment, comprising a box body, further comprising:

[0005] a base fixed to the bottom of the box body;

[0006] a plurality of universal wheels fixed to the bottom of the base;

[0007] a drive wheel fixed to the bottom of the base;

[0008] a release pipe fixedly connected to the top of the box body;

[0009] a spraying machine fixedly installed in the interior of the box body, for atomizing the disinfectant liquid in the interior of the box body and conveying it to the release pipe;

[0010] a feed inlet provided on the top of the box body;

[0011] an air flow driving member installed on the box body, for assisting the atomized disinfectant liquid to be output from the release pipe by air flow, so as to drive the disinfectant liquid to be uniformly sprayed to each position;

[0012] a backflow member installed at the bottom of the release pipe, for discharging backflow disinfectant liquid;

[0013] When disinfection is needed, the staff injects the prepared chlorine dioxide stock solution into the inside of the box through the inlet. When it is necessary to transport the atomized chlorine dioxide to the factory through the air conditioning system, the release pipe is connected to the air supply pipe of the air conditioning system to deliver the atomized chlorine dioxide to the factory. When it is necessary to disinfect a separate factory space, the drive wheel is activated, which drives the base to move, and the base drives the box to move. The box and the inlet move synchronously to disinfect each location.

[0014] When starting the sprayer, a cold mist / aerosol sprayer can be selected. It uses high-speed airflow or ultrasound to break the liquid medicine into fine mist. Usually, by adjusting parameters such as gas-liquid ratio and pressure, the particle size can be stably controlled in the range of 50-150 micrometers. This allows the atomized chlorine dioxide to be discharged along the release pipe. At the same time, the airflow drive is activated, and the airflow can carry the atomized chlorine dioxide to be discharged along the release pipe at a constant speed. The discharged atomized chlorine dioxide can be directly discharged into the factory space for disinfection, or connected to the air conditioning inlet and transported into the factory space by the air conditioning system for disinfection.

[0015] During the disinfection process, the atomized chlorine dioxide will partially flow back due to its contact with the inner wall of the pipe during transportation. The backflowed chlorine dioxide will be recovered through the reflux device, which helps to prevent the backflowed chlorine dioxide from clogging the pipe and affecting the atomization degree and release effect of the atomized chlorine dioxide.

[0016] Preferably, the airflow driving component includes:

[0017] An air pump is fixed to the top of the housing;

[0018] The first delivery pipe has one end connected to the output end of the air pump and the other end connected to the bottom of the side wall of the release pipe.

[0019] After the air pump is started, it can deliver a constant airflow along the first delivery pipe into the inside of the release pipe, thereby forming a constant airflow from bottom to top inside the release pipe. This drives the atomized chlorine dioxide delivered into the release pipe to be delivered from bottom to top in a constant manner, which is conducive to the output of atomized chlorine dioxide with a constant concentration.

[0020] Preferably, the return component includes:

[0021] A hemispherical bottom is fixedly connected to the bottom of the release tube;

[0022] A straight tube, fixedly connected to the bottom of the hemispherical base;

[0023] The fixing plug consists of two round plugs and a fixing frame. The top of the fixing frame is fixed to the inner wall of the hemispherical bottom, and the bottom extends into the interior of the straight tube. Both round plugs are fixed to the outer wall of the fixing frame and are in pressure contact with the inner wall of the straight tube.

[0024] Both rotating plugs are fixed inside the straight tube and have a circular hole in the center. The sidewall of the circular hole is in contact with the outer wall of the fixing frame.

[0025] Multiple openings, two openings are provided through each of the two circular plugs and the two openings are vertically aligned, and two openings are provided through each of the two fixed plugs and the two openings are vertically staggered;

[0026] A driving component, installed inside the housing, is used to drive the straight tube to rotate;

[0027] The condensation generated during the delivery of atomized chlorine dioxide flows downwards into the interior of the hemispherical bottom. When the drive unit rotates the straight tube, it drives the rotating plug to rotate. After the rotating plug rotates, it rotates relative to the fixed plug. When the opening on the upper round plug of the fixed plug and the upper rotating plug is aligned, the opening on the lower round plug of the fixed plug and the lower rotating plug is misaligned. This prevents the interior of the straight tube from being completely unobstructed. Similarly, when the opening on the lower round plug of the fixed plug and the lower rotating plug is aligned, they are aligned individually. This alternating alignment discharges the accumulated chlorine dioxide downwards and prevents the airflow from being delivered downwards. This helps to avoid the accumulation of chlorine dioxide inside the hemispherical bottom, which would affect the delivery effect of atomized chlorine dioxide.

[0028] The driving component is a combination of existing drive motor and drive gear, which is existing technology and will not be described in detail here.

[0029] Preferably, the airflow drive further includes:

[0030] A lifting tube is sleeved over the outside of the release tube;

[0031] The motor is fixed to the top of the housing;

[0032] The gear set is installed on the top of the housing;

[0033] A lead screw is rotatably mounted on the top of the housing. The motor drives the lead screw to rotate through the gear set, and the lead screw is slidably connected to the guide groove on the side wall of the lifting tube via a sliding contact with a threaded trajectory.

[0034] A mist outlet platform is installed on top of the lifting pipe;

[0035] A mist outlet is provided at the edge of the mist outlet platform to connect to the interior of the riser pipe;

[0036] The inner walls of both the lifting tube and the releasing tube are provided with an enamel coating.

[0037] After the motor starts, it drives the gear set to rotate through the output shaft. The gear set drives the lead screw to rotate. After the gear set rotates, it slides through the threaded track of the guide groove on the side wall of the lifting pipe to guide the vertical movement of the lifting pipe, thereby driving the mist outlet to move vertically to adjust the delivery position of the atomized chlorine dioxide, which is conducive to the delivery and disinfection of atomized chlorine dioxide at various positions.

[0038] Preferably, the airflow drive further includes:

[0039] A connecting pipe, installed in the input pipe of the sprayer;

[0040] A floating platform is fixed to the outer wall of the end of the connecting pipe;

[0041] Take a liquid ball and fix it to the end of the connecting tube;

[0042] The floating platform allows the end of the connecting tube to float on the liquid surface, and then the liquid is collected by the liquid collection ball, which helps to avoid the situation where sediment is collected and affects the atomization effect.

[0043] Preferably, the airflow drive further includes:

[0044] Multiple stirring rods are fixed to the bottom of the straight tube in a circumferential array, and the bottom of the straight tube has multiple rectangular openings;

[0045] The rotation of the straight pipe drives the stirring rod to rotate, which in turn stirs the disinfectant liquid inside the tank to reduce sedimentation.

[0046] Preferably, the airflow drive further includes:

[0047] A corrosion inhibitor box is fixed to the top of the box body;

[0048] The second delivery pipe is connected and installed between the corrosion inhibitor tank and the release pipe, and a clearance groove is provided on the side wall of the lifting pipe to allow the second delivery pipe to pass.

[0049] The corrosion inhibitor tank stores corrosion inhibitors, which are then delivered to the release pipe via a second delivery pipe. This allows the atomized chlorine dioxide to carry the corrosion inhibitors out as it passes through, thus reducing the corrosion of the equipment during the chlorine dioxide disinfection process.

[0050] Preferably, the airflow drive further includes:

[0051] A spiral conveyor table is fixed to the inner wall of the release pipe;

[0052] A perforated plate is fixedly embedded on the side of the spiral conveyor table facing the center of the release tube;

[0053] The discharge port is located at the upward-facing end of the spiral conveyor table;

[0054] The spiral conveyor guides the airflow, causing it to flow upwards in a spiral shape. This spiral shape in the discharged airflow helps to increase the spray area of ​​atomized chlorine dioxide. Furthermore, the perforated plate allows some chlorine dioxide to be directly conveyed from the lower right to the top, filling the middle of the spiral airflow and further optimizing the delivery effect of atomized chlorine dioxide.

[0055] Preferably, the airflow drive further includes:

[0056] The first electromagnet is fixed to the top of the fog outlet platform;

[0057] The second electromagnet is fixed to the outer wall of the lifting pipe and located below the mist outlet platform;

[0058] Multiple connecting ropes are fixed to the mist outlet in a circumferential array to connect the top and bottom of the mist outlet, and the edges of the mist outlet are all made of flexible material;

[0059] Two magnets are fixed to the inside of the top and bottom edges of the mist outlet, respectively;

[0060] The alternating activation of the first and second electromagnets can alternately drive the magnetic plates to reciprocate vertically, thereby causing the flexible material at the top and bottom edges of the mist outlet to swing vertically back and forth. The connecting rope can drive the top and bottom edges of the mist outlet to move synchronously, thus adjusting the upward and downward discharge of atomized chlorine dioxide from the outlet. This helps to adjust the discharge direction, increase the discharge angle of atomized chlorine dioxide, and thus increase the discharge area.

[0061] Secondly, a BC30 sterilization method is provided, which includes the following steps:

[0062] Step 1: Preparation of disinfection personnel: When mixing, be sure to wear protective equipment to avoid splashing the undiluted solution into the eyes or mouth and nose during mixing;

[0063] Step 2, Material Preparation: Take chlorine dioxide (powder / tablet) with a concentration of 150-300ppm and water and mix them thoroughly to obtain the stock solution;

[0064] Step 3: Preparation of the disinfection area: Before disinfection, confirm that no one is in the disinfection area and set up warning signs in the disinfection area to prevent people from accidentally entering and causing injury;

[0065] Step 4, Disinfection: Inject the prepared stock solution into the sterilization equipment chamber, place the sterilization equipment inside the air conditioning unit, connect the release pipe to the air conditioning unit, and turn on the sterilization equipment and the air conditioning unit. The chlorine dioxide atomized material blown out by the sterilization equipment is carried into each workshop by the air supply from the air conditioning unit. Select the number of atomization times or duration according to the severity of BC30 (Bacillus).

[0066] Step 5, Disinfection Monitoring: After disinfection, turn off the sterilization equipment, and keep the air conditioning unit running with indoor air circulation for 2-4 hours. Then turn off the air conditioning unit and let it stand for 8 hours. After that, the laboratory personnel will conduct environmental testing and sampling. The test results will determine whether the disinfection is qualified. If it is qualified, the concentration and amount used will be recorded. Subsequent disinfection will be carried out based on this record. If it is not qualified, the above steps will be repeated to increase the concentration of chlorine dioxide or increase the disinfection time.

[0067] Compared with the prior art, the present invention has the following beneficial effects:

[0068] With the airflow drive mechanism, the airflow can drive the atomized chlorine dioxide to be discharged along the release pipe at a constant speed. The discharged atomized chlorine dioxide can be directly discharged into the factory space for disinfection, or connected to the air conditioning inlet and transported into the factory space by the air conditioning system for disinfection.

[0075] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0076] like Figures 2 to 5 The BC30 sterilization equipment shown includes a housing 1, and also includes:

[0077] The base 101 is fixed to the bottom of the housing 1;

[0078] Multiple casters 102 are fixed to the bottom of the base 101;

[0079] Drive wheel 103 is fixed to the bottom of base 101;

[0080] Release tube 104 is fixedly connected to the top of box 1;

[0081] The sprayer 106 is fixedly installed inside the housing 1 and is used to atomize the disinfectant liquid inside the housing 1 and deliver it to the release pipe 104.

[0082] The feed inlet 105 is located at the top of the housing 1;

[0083] An airflow drive unit, installed on the housing 1, is used to assist the atomized disinfectant solution to be output through the release pipe 104 by airflow, so as to drive the disinfectant solution to be evenly sprayed to various positions;

[0084] A return component, installed at the bottom of the release tube 104, is used to discharge the returned disinfectant solution;

[0085] Current solutions mainly focus on complex online generation and vaporization systems, which have high equipment investment and maintenance costs. Furthermore, they lack simple and reproducible operating procedures for precise control of disinfection concentration, uniform distribution within complex air ducts, and standardized verification of the final effect. Therefore, there is a need for a cost-effective, standardized, and verifiable chlorine dioxide disinfection method to solve the above-mentioned problems in existing technologies.

[0086] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: When disinfection is required, the staff injects the prepared chlorine dioxide stock solution into the interior of the box 1 through the inlet 105. When it is necessary to transport atomized chlorine dioxide to the factory through the air conditioning system, the release pipe 104 is connected to the air supply pipe of the air conditioning system to transport atomized chlorine dioxide to the factory. When it is necessary to disinfect a separate factory space, the drive wheel 103 is activated, the drive wheel 103 drives the base 101 to move, the base 101 drives the box 1 to move, and the box 1 and the inlet 105 move synchronously to disinfect each position.

[0087] When the sprayer 106 is started, the sprayer 106 can be a cold mist / aerosol sprayer, which uses high-speed airflow or ultrasound to break the liquid medicine into fine mist. Usually, by adjusting parameters such as gas-liquid ratio and pressure, the particle size can be stably controlled in the range of 50-150 micrometers, so that the atomized chlorine dioxide is discharged along the release pipe 104. At the same time, the airflow drive is started, and the airflow can drive the atomized chlorine dioxide to be discharged along the release pipe 104 at a constant speed. The discharged atomized chlorine dioxide can be directly discharged into the factory space for disinfection, or connected to the air conditioning inlet and transported into the factory space by the air conditioning system for disinfection.

[0088] During the disinfection process, the atomized chlorine dioxide will partially flow back due to its contact with the inner wall of the pipe during transportation. The backflowed chlorine dioxide will be recovered through the reflux device, which helps to prevent the backflowed chlorine dioxide from clogging the pipe and affecting the atomization degree and release effect of the atomized chlorine dioxide.

[0089] As an optional embodiment, the airflow drive includes:

[0090] Air pump 2 is fixed to the top of housing 1;

[0091] The first delivery pipe 201 is connected at one end to the output end of the air pump 2 and at the other end to the bottom of the side wall of the release pipe 104.

[0092] After the air pump 2 is started, it can deliver a constant airflow along the first delivery pipe 201 into the interior of the release pipe 104, thereby forming a constant airflow from bottom to top inside the release pipe 104, which in turn drives the atomized chlorine dioxide delivered to the interior of the release pipe 104 to be delivered from bottom to top in a constant manner, which is beneficial to output atomized chlorine dioxide with a constant concentration.

[0093] As an optional embodiment, the reflow component includes:

[0094] The hemispherical bottom 3 is fixedly connected to the bottom of the release tube 104;

[0095] Straight tube 301 is fixedly connected to the bottom of hemispherical base 3;

[0096] The fixed plug 302 consists of two round plugs and a fixed frame. The top of the fixed frame is fixed to the inner wall of the hemispherical bottom 3, and the bottom extends into the interior of the straight tube 301. Both round plugs are fixed to the outer wall of the fixed frame and are in contact with the inner wall of the straight tube 301.

[0097] Both rotating plugs 303 are fixed inside the straight tube 301, and a circular hole is opened in the center. The side wall of the circular hole is pressed against the outer wall of the fixing frame.

[0098] Multiple openings: two openings are made through each of the two round plugs, and the two openings are vertically aligned; two openings are made through each of the two fixed plugs 302, and the two openings are vertically offset.

[0099] The driving component is installed inside the housing 1 and is used to drive the straight tube 301 to rotate;

[0100] The condensation generated during the conveying of atomized chlorine dioxide flows downward into the interior of the hemispherical bottom 3. When the driving component drives the straight tube 301 to rotate, it drives the rotating plug 303 to rotate. After the rotating plug 303 rotates, it rotates relative to the fixed plug 302. When the upper round plug of the fixed plug 302 and the opening on the upper rotating plug 303 are aligned, the lower round plug of the fixed plug 302 and the opening on the lower rotating plug 303 are misaligned, so that the interior of the straight tube 301 is not completely unobstructed. Similarly, when the lower round plug of the fixed plug 302 and the opening on the lower rotating plug 303 are aligned, they are only aligned individually. Thus, the accumulated chlorine dioxide is discharged downward through alternating alignment, while avoiding the downward conveying of airflow. This helps to prevent the accumulation of chlorine dioxide inside the hemispherical bottom 3 from affecting the conveying effect of atomized chlorine dioxide.

[0101] The driving component is a combination of existing drive motor and drive gear, which is existing technology and will not be described in detail here.

[0102] As an optional embodiment, the airflow drive also includes:

[0103] The lifting pipe 4 is sleeved on the outside of the release pipe 104;

[0104] Motor 401 is fixed to the top of housing 1;

[0105] Gear set 402 is installed on the top of housing 1;

[0106] The lead screw is rotatably mounted on the top of the housing 1. The motor 401 drives the lead screw to rotate through the gear set 402, and the lead screw is slidably connected to the guide groove on the side wall of the lifting tube 4 through the sliding contact with a threaded trajectory.

[0107] The mist outlet 403 is installed on the top of the riser pipe 4;

[0108] The mist outlet 404 is located at the edge of the mist outlet platform 403 to connect to the interior of the riser pipe 4;

[0109] The inner walls of both the riser tube 4 and the release tube 104 are coated with an enamel layer.

[0110] After the motor 401 starts, it drives the gear set 402 to rotate through the output shaft. The gear set 402 drives the lead screw to rotate. After the gear set 402 rotates, it slides through the threaded track of the guide groove on the side wall of the lifting pipe 4 to guide the lifting pipe 4 to move vertically, thereby driving the mist outlet 404 to move vertically to adjust the delivery position of the atomized chlorine dioxide, which is conducive to the delivery and disinfection of atomized chlorine dioxide at various positions.

[0111] As an optional embodiment, the airflow drive also includes:

[0112] Connecting pipe 5 is installed in the input pipe of sprayer 106;

[0113] The floating platform 501 is fixed to the outer wall of the end of the connecting pipe 5;

[0114] Take liquid ball 502 and fix it to the end of connecting tube 5;

[0115] The floating platform 501 allows the end of the connecting pipe 5 to float on the liquid surface, and then the liquid is taken by the liquid taking ball 502, which helps to avoid the situation where the liquid is taken from the sediment and affects the atomization effect.

[0116] As an optional embodiment, the airflow drive also includes:

[0117] Multiple stirring rods 6 are fixed in a circular array at the bottom of a straight tube 301, and the bottom of the straight tube 301 has multiple rectangular openings;

[0118] After the straight pipe 301 rotates, it drives the stirring rod 6 to rotate. The rotation of the stirring rod 6 stirs the disinfectant liquid inside the box 1 to reduce sedimentation.

[0119] As an optional embodiment, the airflow drive also includes:

[0120] Corrosion inhibitor box 7 is fixed to the top of box 1;

[0121] The second delivery pipe 701 is connected between the corrosion inhibitor tank 7 and the release pipe 104, and a clearance groove is provided on the side wall of the lifting pipe 4 to allow the second delivery pipe 701 to make way.

[0122] The corrosion inhibitor tank 7 stores corrosion inhibitors. The corrosion inhibitors are delivered to the release pipe 104 through the second delivery pipe 701, so that the corrosion inhibitors are sprayed out when the atomized chlorine dioxide passes through, which helps to reduce the corrosion of the equipment during the chlorine dioxide disinfection process.

[0123] As an optional embodiment, the airflow drive also includes:

[0124] The spiral conveyor table 8 is fixed on the inner wall of the release pipe 104;

[0125] The perforated plate 801 is fixedly embedded in the spiral conveyor table 8 on the side facing the center of the release tube 104;

[0126] The discharge port 802 is located at the upward-facing end of the screw conveyor table 8;

[0127] The spiral conveyor 8 guides the airflow, causing it to flow upward in a spiral shape. This spiral shape of the discharged airflow helps to increase the spray area of ​​atomized chlorine dioxide. Furthermore, the perforated plate 801 allows some chlorine dioxide to be directly conveyed from the lower right to the top, filling the middle of the spiral airflow and further optimizing the delivery effect of atomized chlorine dioxide.

[0128] As an optional embodiment, the airflow drive also includes:

[0129] The first electromagnet 9 is fixed to the top of the fog outlet platform 403;

[0130] The second electromagnet 902 is fixed on the outer wall of the lifting pipe 4 and located below the mist outlet platform 403;

[0131] Multiple connecting ropes 901 are fixed to the mist outlet 404 in a circumferential array to connect the top and bottom of the mist outlet 404, and the edges of the mist outlet 404 are all made of flexible material.

[0132] Two magnetic pieces are fixed to the inside of the top and bottom edges of the mist outlet 404, respectively;

[0133] The alternating activation of the first electromagnet 9 and the second electromagnet 902 can alternately drive the magnetic plate to reciprocate vertically, thereby causing the flexible material at the top and bottom edges of the mist outlet 404 to swing vertically back and forth. The connecting rope 901 can drive the top and bottom edges of the mist outlet 404 to move synchronously, thereby adjusting the upward and downward discharge of the atomized chlorine dioxide outlet. This helps to adjust the discharge direction, increase the discharge angle of the atomized chlorine dioxide, and thus increase the discharge area.

[0134] like Figure 1 The BC30 sterilization method shown includes the following steps:

[0135] Step 1: Preparation of disinfection personnel: When mixing, be sure to wear protective equipment to avoid splashing the undiluted solution into the eyes or mouth and nose during mixing;

[0136] Step 2, Material Preparation: Take chlorine dioxide (powder / tablet) with a concentration of 150-300ppm and water and mix them thoroughly to obtain the stock solution;

[0137] Step 3: Preparation of the disinfection area: Before disinfection, confirm that no one is in the disinfection area and set up warning signs in the disinfection area to prevent people from accidentally entering and causing injury;

[0138] Step 4, Disinfection: Inject the prepared stock solution into the chamber 1 of the sterilization equipment, place the sterilization equipment inside the air conditioning unit, connect the release pipe 104 to the air conditioning unit, and turn on the sterilization equipment and the air conditioning unit. The chlorine dioxide atomized material blown out by the sterilization equipment is carried into each workshop by the air supply of the air conditioning unit. Select the number of atomization times or duration according to the severity of BC30 (Bacillus subtilis).

[0139] Step 5, Disinfection Monitoring: After disinfection, turn off the sterilization equipment, and keep the air conditioning unit running with indoor air circulation for 2-4 hours. Then turn off the air conditioning unit and let it stand for 8 hours. After that, the laboratory personnel will conduct environmental testing and sampling. The test results will determine whether the disinfection is qualified. If it is qualified, the concentration and amount used will be recorded. Subsequent disinfection will be carried out based on this record. If it is not qualified, the above steps will be repeated to increase the concentration of chlorine dioxide or increase the disinfection time.

[0140] The working principle of this invention is as follows: When disinfection is required, the staff injects the prepared chlorine dioxide stock solution into the interior of the box 1 through the inlet 105. When it is necessary to transport the atomized chlorine dioxide to the factory through the air conditioning system, the release pipe 104 is connected to the air supply pipe of the air conditioning system, thereby transporting the atomized chlorine dioxide to the factory. When it is necessary to disinfect a separate factory space, the drive wheel 103 is activated, which drives the base 101 to move. The base 101 drives the box 1 to move, and the box 1 and the inlet 105 move synchronously to disinfect each location.

[0141] When the sprayer 106 is started, the sprayer 106 can be a cold mist / aerosol sprayer, which uses high-speed airflow or ultrasound to break the liquid medicine into fine mist. Usually, by adjusting parameters such as gas-liquid ratio and pressure, the particle size can be stably controlled in the range of 50-150 micrometers, so that the atomized chlorine dioxide is discharged along the release pipe 104. At the same time, the airflow drive is started, and the airflow can drive the atomized chlorine dioxide to be discharged along the release pipe 104 at a constant speed. The discharged atomized chlorine dioxide can be directly discharged into the factory space for disinfection, or connected to the air conditioning inlet and transported into the factory space by the air conditioning system for disinfection.

[0142] During the disinfection process, the atomized chlorine dioxide will partially flow back due to its contact with the inner wall of the pipe during transportation. The backflowed chlorine dioxide will be recovered through the reflux device, which helps to prevent the backflowed chlorine dioxide from clogging the pipe and affecting the atomization degree and release effect of the atomized chlorine dioxide.

[0143] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
