Description

Technical Field

[0001] The present invention particularly relates to a gas supply device and a bactericide supply method. Background Art

[0002] Currently, commercially available gas supply equipment typically vaporizes fungicides such as hydrogen peroxide and then delivers them to a spraying device for disinfection. However, because the vaporized fungicide cannot be kept warm during delivery to the spraying device, it easily condenses and forms liquid hydrogen peroxide, a less effective form of hydrogen peroxide, significantly reducing its effectiveness. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a gas supply device to solve the problem of condensation of sterilizing gas during transmission.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a gas supply device, comprising a quantitative device for quantitatively storing a sterilant, a gasification device for gasifying the sterilant, and a spraying device for spraying sterilizing gas, and also comprising a steam generating device for assisting the gasification device in heating up. A double-layer transmission pipe is connected between the spraying device and the gasification device. The double-layer transmission pipe comprises an inner pipe and an outer pipe that are connected to each other. The inner pipe forms a sterilization channel. The sterilization channel is respectively connected to the gasification device and the spraying device for sterilizing gas to pass through. An insulation channel is formed between the inner pipe and the outer pipe, and the insulation channel is connected to the steam generating device to transport high-temperature water vapor.

[0005] In the above-mentioned air supply equipment, the spraying device includes a horizontally arranged air collecting pipe and a plurality of nozzles installed on the air collecting pipe, and the nozzles are connected to the sterilization channel through the air collecting pipe.

[0006] In the above-mentioned gas supply equipment, an insulation shell is provided on the outer side of the gas collecting pipe, and an insulation cavity is formed between the inner side wall of the insulation shell and the outer side wall of the gas collecting pipe, and the insulation cavity is connected to the insulation channel.

[0007] In the above-mentioned air supply equipment, an air inlet pipe and an air outlet pipe communicating with the heat preservation cavity are respectively provided at both ends of the heat preservation shell, and the heat preservation cavity is communicated with the heat preservation channel through the air inlet pipe.

[0008] The above-mentioned air supply equipment further includes a sterile chamber for accommodating the spraying device. A mounting hole is provided on the top plate of the sterile chamber, and the double-layer transmission pipe is sealed and inserted into the mounting hole.

[0009] In the above-mentioned air supply equipment, the double-layer transmission pipe includes a first transmission section and a second transmission section that are separately arranged. An upper pressure plate is wrapped around the outer wall of the first transmission section, and a lower pressure plate is wrapped around the outer wall of the second transmission section. The first transmission section and the second transmission section are sealed and plugged together so that the upper pressure plate and the lower pressure plate jointly clamp the top plate of the sterile warehouse.

[0010] In the above-mentioned gas supply equipment, the gasification device has a temperature rising chamber and a gasification chamber separated from each other. The gasification chamber is connected to the quantitative device. A gasification plate is provided in the gasification chamber. The temperature rising chamber is connected to the steam generating device. The gasification plate is heated through the gasification chamber to gasify the sterilant dripping on the gasification plate.

[0011] In the above-mentioned gas supply equipment, the temperature rising chamber is arranged around the gasification chamber.

[0012] The beneficial effects of the present invention are:

[0013] A gas supply device includes a metering device for quantitatively storing a sterilant, a gasification device for gasifying the sterilant, and a spraying device for spraying sterilizing gas. It also includes a steam generator to assist in heating the gasification device. A double-layer transmission pipe is connected between the spraying device and the gasification device. The double-layer transmission pipe includes an inner tube and an outer tube that are connected to each other. The inner tube forms a sterilization channel, which is connected to the gasification device and the spraying device respectively to allow the sterilizing gas to pass through. A heat preservation channel is formed between the inner and outer tubes, and the heat preservation channel is connected to the steam generator to transport high-temperature water vapor. This technical solution has the following technical effects:

[0014] The present invention provides a double-layer transmission pipe having both a sterilization channel and a heat preservation channel between the gasification device and the spraying device, so that the double-layer transmission pipe can transport sterilization gas between the gasification device and the spraying device through the sterilization channel, while the heat preservation channel surrounding the sterilization channel can also allow high-temperature water vapor generated by the steam generating device to pass through. When the high-temperature water vapor passes through the heat preservation channel, it can keep the surrounding of the sterilization channel warm. When the gas supply equipment is in a cold environment caused by geographical location or extreme weather, the high-temperature water vapor in the heat preservation channel surrounds the surrounding of the sterilization channel, which can prevent the sterilization gas from condensing due to heat exchange with the external environment during the transportation process of the sterilization channel, and ensure that the sterilization gas transported to the spraying device for spraying is a sterilization gas with a strong sterilization function, rather than a liquid sterilant with a poor sterilization effect, thereby ensuring the sterilization effect and allowing the gas supply equipment to operate stably in a cold environment, with a wider range of applications.

[0015] The spraying device includes a horizontally arranged gas manifold and multiple nozzles mounted on the manifold. The nozzles are connected to the sterilization channel through the manifold. The horizontal manifold allows sterilizing gas to be transported within the manifold and simultaneously ejected through multiple nozzles. This allows sterilizing gas to be sprayed simultaneously on multiple items to be sterilized or over a wide area of ​​the sterile chamber, improving the spraying device's sterilization efficiency.

[0016] The outer surface of the gas collecting pipe is covered with an insulation shell. An insulation cavity is formed between the inner wall of the insulation shell and the outer wall of the gas collecting pipe. The insulation cavity is connected to the insulation channel. After the high-temperature water vapor in the insulation channel heats the sterilizer in the sterilization channel, it enters the insulation cavity through the air inlet pipe and eventually exits the insulation cavity through the air outlet pipe. The high-temperature water vapor passing through the insulation cavity insulates the sterilizing gas in the gas collecting pipe, preventing condensation of the sterilizing gas in the gas collecting pipe and making better use of the high-temperature water vapor.

[0017] An air inlet pipe and an air outlet pipe, each connected to the insulation chamber, are provided at each end of the insulation shell. The insulation chamber is connected to the insulation channel via the air inlet pipe. By connecting the air inlet pipe and the air outlet pipe to the ends of the insulation shell, high-temperature water vapor entering the insulation chamber through the air inlet pipe must pass through the entire gas collection pipe before being discharged through the air outlet pipe. This fully utilizes the high-temperature water vapor and prevents large temperature differences at various locations on the gas collection pipe due to uneven distribution of high-temperature water vapor in the insulation chamber. This ensures that the insulation chamber effectively insulates the sterilizing gas within the gas collection pipe.

[0018] The double-layer transmission tube includes a first transmission section and a second transmission section, each of which is separately arranged. An upper pressure plate is wound around the outer wall of the first transmission section, and a lower pressure plate is wound around the outer wall of the second transmission section. The first and second transmission sections are sealed and plugged together so that the upper and lower pressure plates jointly clamp the top plate of the sterile chamber. The upper and lower pressure plates jointly clamp the top plate of the sterile chamber to secure the double-layer transmission tube to the top plate of the sterile chamber. Because the upper and lower pressure plates can respectively block and seal the top and bottom of the mounting hole, the double-layer transmission tube can be secured while also being sealed between the double-layer transmission tube and the mounting hole. This results in a simple structure and facilitates assembly.

[0019] The vaporization device comprises a separate heating chamber and a vaporization chamber. The vaporization chamber is connected to the metering device and houses a vaporization plate. The heating chamber is connected to the steam generator. The vaporization plate is heated by the vaporization chamber, vaporizing the fungicide dripping onto the plate. The steam generator simultaneously vaporizes the fungicide within the vaporization device and insulates the double-layer transmission pipe, fully utilizing the high-temperature steam generated by the steam generator. This eliminates the need for additional insulation components and simplifies the internal structure of the gas supply device.

[0020] The heating chamber is arranged around the gasification chamber so that the gasification chamber is surrounded by the heating chamber, thereby improving the heat exchange efficiency between the gasification chamber and the heating chamber, ensuring that the gasification chamber is always in a high temperature state, and improving the gasification efficiency of the bactericide.

[0021] The present invention also provides a fungicide supply method, comprising the following steps:

[0022] In the first step, the quantitative device transfers a quantitative amount of bactericide to the gasification device;

[0023] In the second step, the steam generator generates high-temperature steam and simultaneously transmits it to the heating chamber of the vaporization device and the insulation channel of the double-layer transmission pipe. When passing through the heating chamber and the insulation channel, the high-temperature steam exchanges heat with the vaporization chamber and the sterilization channel, thereby raising the temperature in the vaporization chamber and the sterilization channel.

[0024] In the third step, the vaporization plate in the vaporization chamber is heated up. When the bactericide enters the vaporization device and contacts the high-temperature vaporization plate, it is vaporized into a sterilizing gas.

[0025] In the fourth step, the sterilizing gas is transmitted to the spraying device through the sterilizing channel for spraying.

[0026] The features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The present invention proposes a gas supply device, comprising a metering device for quantitatively storing a sterilant, a gasification device for gasifying the sterilant, and a spraying device for spraying sterilizing gas. The device also comprises a steam generator for assisting the gasification device in heating up. A double-layer transmission pipe is connected between the spraying device and the gasification device. The double-layer transmission pipe comprises an inner pipe and an outer pipe that are connected to each other. The inner pipe forms a sterilization channel, which is connected to the gasification device and the spraying device respectively for passing sterilizing gas. An insulation channel is formed between the inner pipe and the outer pipe, which is connected to the steam generator for conveying high-temperature water vapor. The present invention provides a double-layer transmission pipe having both a sterilization channel and an insulation channel between the gasification device and the spraying device. This allows the double-layer transmission pipe to convey sterilizing gas between the gasification device and the spraying device through the sterilization channel. At the same time, the insulation channel surrounding the sterilization channel can also convey high-temperature water vapor generated by the steam generator. When the high-temperature water vapor passes through the insulation channel, it can insulate the surrounding side of the sterilization channel. When the gas supply equipment is in a cold environment caused by geographical location or extreme weather, the high-temperature water vapor in the insulation channel surrounds the sterilization channel, which can prevent the sterilization gas from condensing due to heat exchange with the external environment during the transportation process in the sterilization channel. It ensures that the sterilization gas transported to the spraying device for spraying is a sterilization gas with a strong sterilization function, rather than a liquid sterilant with poor sterilization effect. The sterilization effect is guaranteed, so that the gas supply equipment can work stably in a cold environment and has a wider range of applications.

[0045] Example 1:

[0046] A gas supply device, such as Figures 1 to 4As shown, the apparatus comprises a metering device 100, a vaporizing device 200, a spraying device 400, and a steam generating device 500. The metering device 100 is used to quantitatively store a sterilant (liquid hydrogen peroxide, etc.); the vaporizing device 200 is connected to the output end of the metering device 100 to vaporize the sterilant delivered to the vaporizing device 200 into a sterilizing gas; the spraying device 400 is connected to the output end of the vaporizing device 200 to spray the sterilizing gas produced by the vaporizing device 200; and the steam generating device 500 is connected to the vaporizing device 200 to deliver high-temperature water vapor into the vaporizing device 200 to assist in heating the vaporizing device 200 and vaporizing the sterilant into a sterilizing gas. A double-layer transmission pipe 300 is connected between the output end of the vaporization device 200 and the spraying device 400. The double-layer transmission pipe 300 includes an inner tube 310 and an outer tube 320. The inner tube 310 encloses a sterilization channel 311, and the outer tube 320 is sleeved on the outside of the inner tube 310 to form a heat preservation channel 321 between the inner tube 310 and the outer tube 320. The inlet of the sterilization channel 311 is connected to the vaporization device 200, and the outlet of the sterilization channel 311 is connected to the spraying device 400, which is used to transport the sterilizing gas in the vaporization device 200 to the spraying device 400. The heat preservation channel 321 is connected to the steam generator 500. The high-temperature water vapor generated by the steam generator 500 can keep the sterilizing gas in the sterilization channel 311 warm when passing through the heat preservation channel 321 to prevent condensation of the sterilizing gas.

[0047] The present invention sets a double-layer transmission pipe 300 having both a sterilization channel 311 and a heat preservation channel 321 between the gasification device 200 and the spraying device 400, so that the double-layer transmission pipe 300 can transport sterilization gas between the gasification device 200 and the spraying device 400 through the sterilization channel 311, while the heat preservation channel 321 surrounding the sterilization channel 311 can also allow high-temperature water vapor generated by the steam generating device 500 to pass through. When the high-temperature water vapor passes through the heat preservation channel 321, it can insulate the surrounding side of the sterilization channel 311. When the gas supply equipment is in a cold environment caused by geographical location or extreme weather, the high-temperature water vapor in the insulation channel 321 surrounds the sterilization channel 311, which can prevent the sterilization gas from condensing due to heat exchange with the external environment during the transportation process in the sterilization channel 311, and ensure that the sterilization gas transported to the spraying device 400 for spraying is a sterilization gas with a strong sterilization function, rather than a sterilant with poor sterilization effect, thereby ensuring the sterilization effect, so that the gas supply equipment can also work stably in a cold environment, with a wider range of applications, and can ensure aseptic filling when used on a filling line.

[0048] like Figure 2As shown, in this embodiment, the spraying device 400 includes a gas manifold 410 with both ends closed and a plurality of nozzles 420 mounted on the gas manifold 410. The gas manifold 410 is arranged horizontally, and the plurality of nozzles 420 are evenly spaced along the axial direction of the gas manifold 410 at the bottom of the gas manifold 410. The bottom of the double-layer transmission pipe 300 is connected to the middle of the gas manifold 410, and the nozzles 420 are connected to the sterilization channel 311 through the gas manifold 410. The horizontally arranged gas manifold 410 allows sterilizing gas to be transmitted within the gas manifold 410 of the spraying device 400 and simultaneously sprayed through the plurality of nozzles 420, thereby simultaneously spraying sterilizing gas on multiple items to be sterilized or a sterile warehouse with a wide range, thereby improving the sterilization efficiency of the spraying device 400.

[0049] like Figure 3 and Figure 4 As shown, an insulation shell 430 is provided on the outside of the air collecting pipe 410, and the insulation shell 430 is wrapped around the outside of the air collecting pipe 410. The nozzle 420 passes through the insulation shell 430 to form an insulation cavity 431 between the inner wall of the insulation shell 430 and the outer wall of the air collecting pipe 410. An air inlet pipe 432 and an air outlet pipe 433 are provided at both ends of the insulation shell 430. One end of the air inlet pipe 432 is connected to the insulation channel 321, and the other end is connected to the insulation cavity 431. One end is connected to the insulation chamber 431, and the other end is connected to the outside world, so that the high-temperature water vapor in the insulation channel 321 will enter the insulation chamber 431 through the air inlet pipe 432 after insulating the sterilizer in the sterilization channel 311 and finally be discharged from the insulation chamber 431 through the air outlet pipe 433. The high-temperature water vapor passing through the insulation chamber 431 can insulate the sterilization gas in the gas collecting pipe 410, prevent the sterilization gas from condensing in the gas collecting pipe 410, and make more full use of the high-temperature water vapor. Preferably, the air inlet pipe 432 and the air outlet pipe 433 are respectively connected to the two ends of the insulation shell 430, so that the high-temperature water vapor entering the insulation chamber 431 through the air inlet pipe 432 needs to pass through the entire gas collecting pipe 410 and then be discharged from the air outlet pipe 433, so as to make full use of the high-temperature water vapor and prevent large temperature differences at various positions of the gas collecting pipe 410 due to uneven distribution of high-temperature water vapor in the insulation chamber 431, thereby ensuring the insulation effect of the insulation chamber 431 on the sterilization gas in the gas collecting pipe 410.

[0050] The air supply equipment in this embodiment also includes a sterile chamber, and the spraying device 400 is installed in the sterile chamber. A mounting hole is provided on the top plate of the sterile chamber. The double-layer transmission pipe 300 is inserted into the sterile chamber through the mounting hole to be connected to the spraying device 400. The installation is simple and convenient. The double-layer transmission pipe 300 is sealed and plugged into the mounting hole to ensure the sterile environment of the sterile chamber.

[0051] Preferably, in this embodiment, the double-layer transmission tube 300 includes a first transmission section 330 and a second transmission section 340, and the first transmission section 330 and the second transmission section 340 are separately arranged. The first transmission section 330 is located outside the sterile warehouse, and the upper end of the first transmission section 330 is connected to the gasification device 200. An upper pressure plate 331 is provided around the lower end of the outer wall of the first transmission section 330. The second transmission section 340 is located in the sterile warehouse, and the lower end of the second transmission section 340 is connected to the spraying device 400. A lower pressure plate 341 is provided around the upper end of the outer wall of the second transmission section 340. When installing the double-layer transmission tube 300 and the sterile warehouse, the first transmission section 330 and the second transmission section 340 can be plugged in through the mounting hole. When the first transmission section 330 and the second transmission section 340 are sealed and plugged in, the upper pressure plate 331 is against the top surface of the top plate of the sterile warehouse, and the lower pressure plate 341 is against the bottom surface of the top plate of the sterile warehouse. The top plate of the sterile warehouse is clamped together by the upper pressure plate 331 and the lower pressure plate 341 to achieve the fixation of the double-layer transmission tube 300 on the top plate of the sterile warehouse. Because the upper pressure plate 331 and the lower pressure plate 341 can respectively block and close the top and bottom of the mounting hole, the double-layer transmission tube 300 can be fixed while the sealing between the double-layer transmission tube 300 and the mounting hole can be achieved. The structure is simple and easy to assemble.

[0052] In this embodiment, the vaporization device 200 has a temperature rising chamber 210 and a vaporization chamber 220. The temperature rising chamber 210 and the vaporization chamber 220 are separated from each other. The temperature rising chamber 210 is connected to the steam generating device 500. The vaporization chamber 220 is respectively connected to the quantitative device 100 and the sterilization channel 311 of the double-layer transmission tube 300. A vaporization plate is provided in the vaporization chamber 220. When sterilization is required, the high-temperature steam generated by the steam generating device 500 is simultaneously transmitted to the heating chamber 210 of the vaporization device 200 and the insulation channel 321 of the double-layer transmission tube 300. The high-temperature steam entering the heating chamber 210 surrounds the vaporization chamber 220 and exchanges heat with it, thereby heating the vaporization chamber 220 and the vaporization plates therein to a high temperature. The sterilant entering the vaporization chamber 220 vaporizes into sterilizing gas upon contact with the high-temperature vaporization plates, and is then transported to the spraying device 400 through the sterilization channel 311. During the transport process, the high-temperature steam entering the insulation channel 321 of the double-layer transmission tube 300 surrounds the sterilization channel 311 and exchanges heat with it, thereby heating the sterilization channel 311 to a high temperature, insulating the sterilizing gas therein and preventing condensation therein.

[0053] The high-temperature steam generated by the steam generator 500 simultaneously vaporizes the sterilant within the vaporization device 200 and insulates the double-layer transmission pipe 300. This fully utilizes the high-temperature steam generated by the steam generator 500, eliminating the need for additional insulation components and simplifying the internal structure of the gas supply equipment. Preferably, the warming chamber 210 is disposed around the vaporization chamber 220, so that the vaporization chamber 220 is surrounded by the warming chamber 210. This improves the heat exchange efficiency between the vaporization chamber 220 and the warming chamber 210, ensuring that the vaporization chamber 220 is always at a high temperature, thereby improving the vaporization efficiency of the sterilant.

[0054] Example 2:

[0055] A method for supplying a fungicide, such as Figure 5 As shown, the following steps are included:

[0056] In step 601 , a quantitative device transfers a quantitative amount of sterilant to a gasification device.

[0057] In step 602, the steam generating device generates high-temperature water vapor and transmits it to the gasification device and the double-layer transmission pipe at the same time; the high-temperature water vapor entering the heating chamber of the gasification device surrounds the side of the gasification chamber and exchanges heat with the gasification chamber to heat the gasification chamber; the high-temperature water vapor entering the insulation channel of the double-layer transmission pipe surrounds the side of the sterilization channel and exchanges heat with the sterilization channel to heat the sterilization channel.

[0058] In step 603, the vaporization plate in the vaporization chamber is heated together with the vaporization chamber. When the sterilant enters the vaporization chamber of the vaporization device, the sterilant contacts the high-temperature vaporization plate and is vaporized into sterilizing gas.

[0059] In step 604, the sterilizing gas in the vaporization chamber is transported through the sterilization channel of the double-layered transmission tube to the gas collection pipe of the spraying device, and then sprayed through the nozzle of the spraying device. During the transportation process, the high-temperature steam in the insulation channel keeps the sterilizing gas in the sterilization channel warm, and the high-temperature steam in the insulation chamber also keeps the sterilizing gas in the gas collection pipe warm.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
