Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a gas filtering and purification system. Background Art

[0002] Medical treatment not only refers to medical waste, but also refers to waste gases that are directly or indirectly infectious, toxic or otherwise hazardous and are generated by medical institutions in the course of medical treatment, prevention, health care and other related activities. In addition, gas purification equipment is required to purify the pathogens and toxic gases generated by them, so as to avoid affecting the health of medical staff and patients.

[0003] Existing conventional gas filters are of the connector type. In order to improve the overall filtering effect, the gas usually needs to stay in the filter device for a long time for filtration, which will cause the overall footprint of the filter device to be larger. During conventional use, it will be limited by the area, thereby reducing the overall practicality of the device. In addition, it is difficult for the existing filter to effectively contact the gas, resulting in poor filtering effect.

[0004] To sum up, the above structure occupies a large area of ​​the filtering device as a whole during use. During normal use, it will be limited by the area, thereby reducing the overall practicality of the device. In addition, the existing filter is difficult to effectively contact the gas, resulting in poor filtering effect. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a gas filtration and purification system to solve the technical problems that when in use, it will be limited by the area, thereby reducing the overall practicality of the device, and the existing filter is difficult to effectively contact the gas, resulting in poor filtering effect.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a gas filtration and purification system, comprising a cylinder, an inner groove is provided inside the cylinder, an arc-shaped filter plate is provided on the top of the inner groove, and an array of filter holes is provided on the arc-shaped filter plate, a filter assembly is installed at the bottom of the arc-shaped filter plate in the cylinder, a spiral flow channel is provided in the interlayer of the cylinder, and the bottom of the inner groove is connected to the spiral flow channel, and a catalytic reaction assembly is installed in the spiral flow channel.

[0007] By adopting the above technical solution, the gas is introduced into the inner groove through the air inlet, and the gas will impact the top of the curved filter plate, causing the gas to diffuse on the curved filter plate. In this process, the diffusion area of ​​the gas entering is expanded, and the contact area between the gas and the filter component is further increased. At the same time, when the gas flows through the bottom, it is discharged to the air outlet under the action of the spiral flow channel. In this process, the flow path of the gas is extended in the cylinder, thereby extending the filtration and purification time of the gas in the cylinder.

[0008] The utility model is further configured such that an air inlet and an air outlet are respectively provided on the top of the cylinder, the inner groove is connected to the air inlet, and one end of the spiral flow channel is connected to the air outlet.

[0009] By adopting the above technical solution, under the action of the air inlet, the staff connects it with the filtered and purified gas, so that the gas is directly discharged into the inner tank through the air inlet. At the same time, under the action of the exhaust port, the gas filtered at the bottom of the inner tank is purified through the spiral flow channel and then discharged at the exhaust port, thereby completing the overall filtering and purification work.

[0010] The present invention is further configured such that an electric heating component cooperating with the catalytic reaction component is provided on one side of the spiral flow channel in the interlayer of the cylinder.

[0011] By adopting the above technical solution, when the filtered gas passes through the spiral flow channel, the catalytic reaction component in the spiral flow channel is heated by starting the electric heating component, thereby completing the effective purification of the gas passing through the spiral flow channel.

[0012] The present invention is further configured such that a horizontal end surface is provided at the top end of the arc-shaped filter plate, and the horizontal end surface is sealed, and an array of filter holes is provided on the outer wall of the arc-shaped filter plate located at the horizontal end surface.

[0013] By adopting the above technical solution, when the gas flows into the inner groove through the air inlet, it will first come into contact with the horizontal end surface of the arc-shaped filter plate. During this process, the gas impacts the horizontal end surface of the sealing setting, causing the gas to spread out and at the same time be discharged downward through the outer filter holes, thereby diffusing the overall area of ​​the gas and further increasing the contact area between the gas and the filter component.

[0014] The utility model is further configured such that the inner groove and the spiral flow channel are connected via an air pipe, and both ends of the air pipe are sealed between the inner groove and the spiral flow channel respectively.

[0015] By adopting the above technical solution, when flowing outward through the air outlet, the gas at the bottom of the inner tank will be discharged into the spiral flow channel through the air pipe. In this process, the sealing setting prevents leakage between the spiral flow channel and the bottom of the inner tank, further improving the overall filtration and purification effect.

[0016] The present invention is further configured such that a controller is provided on the outer wall of the cylinder, and the controller is electrically connected to the electric heating component.

[0017] By adopting the above technical solution, the staff can adjust the temperature of the electric heating component itself through the action of the controller, and adjust the temperature according to different gases, thereby further improving the purification effect of the gas.

[0018] The present invention is further configured such that the filter assembly is detachably disposed within the inner tank.

[0019] By adopting the above technical solution, the detachable setting makes it easy for staff to disassemble and replace the filter assembly, thereby improving the subsequent filtering effect on the gas.

[0020] The present invention is further configured such that the electric heating component itself is arranged in a surrounding manner.

[0021] By adopting the above technical solution, the surrounding arrangement facilitates improving the heating effect of the electric heating component on the catalytic reaction component, ensuring that the catalytic reaction component is heated evenly.

[0022] In summary, the present invention has the following beneficial effects:

[0023] The utility model passes the filtered and purified gas into the inner groove through the air inlet, and the gas will impact the top of the arc filter plate, causing the gas to diffuse on the arc filter plate, and then be blown to the filter component at the bottom under the action of the filter holes. In this process, the diffusion area for the gas to enter is enlarged, and the contact area between the gas and the filter component is further improved, thereby ensuring its own filtering effect. At the same time, when the gas flows through the bottom, it is discharged to the air outlet under the action of the spiral flow channel. In this process, the flow path of the gas is extended in the cylinder, thereby extending the filtering and purification time of the gas in the cylinder, reducing the overall footprint of the device while improving the overall practicality of the device.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] The following describes an embodiment of the present invention based on its overall structure.

[0030] Example 1

[0031] A gas filtration and purification system, such as Figure 1-Figure 3 As shown, it includes a cylinder 1, an air inlet 2, an air outlet 3, a heating mechanism and a flow mechanism. An air inlet 2 is provided at the top of the cylinder 1, and an inner tank 4 is opened inside the cylinder 1, wherein the inner tank 4 is connected to the air inlet 2. Under the action of the air inlet 2, the staff connects it with the filtered and purified gas, so that the gas is directly discharged into the inner tank 4 through the air inlet 2. At the same time, an arc filter plate 7 is provided on the top of the inner tank 4, and an array of filter holes is opened on the arc filter plate 7, and a filter component 8 is installed at the bottom of the arc filter plate 7 in the cylinder 1. The gas will impact the top of the arc filter plate 7, so that the gas diffuses on the arc filter plate 7, and then is blown to the filter component 8 at the bottom under the action of the filter holes. In this process, the diffusion area of ​​the gas entering is expanded, and the contact area between the gas and the filter component 8 is further improved, thereby ensuring its own filtering effect, and then the filtered gas will flow to the bottom of the inner tank 4. The air in the cylinder 1 is blown out of the air and is then blown away by the exhaust pipe 3. The exhaust pipe 3 is used to blow out the air into the cylinder 1 , thereby effectively reducing the leakage of the air.

[0032] See also Figure 1 and Figure 2 The inner tank 4 and the spiral flow channel 5 are connected by an air pipe, and the two ends of the air pipe are sealed between the inner tank 4 and the spiral flow channel 5 respectively. When flowing outward through the air outlet 3, the gas at the bottom of the inner tank 4 will be discharged into the spiral flow channel 5 through the air pipe. In this process, the sealing setting prevents leakage from the spiral flow channel 5 and the bottom of the inner tank 4, further improving the overall filtering and purification effect.

[0033] Example 2

[0034] See also Figure 2 , a gas filtration and purification system is shown, and its overall structure is similar to that of Example 1, wherein a horizontal end face is provided at the top of the arc-shaped filter plate 7, and the horizontal end face is sealed. An array of filter holes is provided on the outer wall of the arc-shaped filter plate at the horizontal end face. When the gas flows into the inner groove 4 through the air inlet 2, it will first contact the horizontal end face of the arc-shaped filter plate 7. During this process, the gas impacts the horizontal end face of the sealed setting, which will cause the gas to spread out and at the same time be discharged downward through the outer filter holes, thereby diffusing the overall area of ​​the gas and further increasing the contact area between the gas and the filter component 8.

[0035] The working principle of the present utility model is as follows: when in use, the gas to be filtered and purified is connected to the air inlet 2, and then the gas is blown onto the arc filter plate 7 in the inner tank 4. At this time, the gas diffuses to the surroundings at the top of the arc filter plate 7, and then is discharged to the filter component 8 through its own filter holes. In this process, the diffusion area for the gas to enter is expanded, and the contact area between the gas and the filter component 8 is further increased. When the gas flows through the bottom of the inner tank 4, the gas flows through the spiral flow channel 5 under the action of the air outlet 3. Under the action of the catalytic reaction component and the electric heating component 9 in the spiral flow channel 5, the gas is purified. In this process, the flow path of the gas is extended in the cylinder 1, thereby extending the filtering and purification time of the gas in the cylinder 1.
