Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, specifically to a waste gas purification device for medical waste treatment. Background Technology

[0002] Medical waste refers to waste generated during medical treatment, prevention, healthcare, and other related activities that possess direct or indirect infectiousness, toxicity, or other hazards. During the treatment of medical waste (such as incineration, high-temperature sterilization, and chemical disinfection), harmful gases may be generated, primarily including acidic gases, dioxins, heavy metals (mercury, lead), volatile organic compounds, and particulate matter. If these gases are not effectively treated, they can cause serious harm to the environment and human health.

[0003] An investigation revealed that a Chinese utility model patent discloses a waste gas purification device for treating organic solid waste (publication number: CN217849877U), which includes a base, a conveying fan, a combustion treatment box, a spray treatment box, and a filter treatment box. The conveying fan is fixedly installed on the left side of the upper end of the base, the combustion treatment box is fixedly installed on the right side of the upper end of the base located on the upper end of the base located on the upper end of the base located on the right side of the combustion treatment box, and the spray treatment box is fixedly installed on the right side of the upper end of the base located on the upper end of the base located on the upper end of the base located on the right side of the combustion treatment box.

[0004] While the aforementioned patent, through the installation of a combustion treatment box, a spray treatment box, and a filtration treatment box, allows waste gas to be sent to the combustion treatment box via a conveyor fan during waste purification, where a gas pump injects appropriate amounts of oxygen and catalyst, causing the waste gas to undergo combustion treatment to burn the combustible gases in the waste gas, achieving preliminary purification, and then the combusted waste gas enters the spray treatment box for spray treatment to remove particulate matter, and finally passes through the filtration treatment box for purification, thus improving the purification effect, reducing environmental pollution, effectively removing combustion gases, and reducing the safety hazards of the purification device, the above solution, in use, involves sealing the filter plates and activated carbon plates in the filtration treatment box. This makes it inconvenient to remove the filter plates and activated carbon plates from the filtration treatment box for cleaning and replacement, making the filter plates and activated carbon plates prone to clogging or damage during long-term use, thereby reducing the purification effect of the device.

[0005] Therefore, this utility model provides a waste gas purification device for medical waste treatment to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-5 As shown, this utility model provides a waste gas purification device for medical waste treatment, including a conveying fan 1. A combustion chamber 2, a spray chamber 3, and a filter chamber 4 are sequentially arranged on one side of the conveying fan 1. The conveying fan 1 and the combustion chamber 2 are connected by a first connecting pipe 5. The combustion chamber 2 and the spray chamber 3 are connected by a second connecting pipe 6.

[0028] The first filtration mechanism 8 includes a movable plate 801. The outer wall of the movable plate 801 is movably connected to the inner wall of the filter box 4. Multiple slots 802 are equidistantly arranged inside the movable plate 801. The movable plate 801 is connected to multiple inserts 803 through the multiple slots 802. The top ends of two adjacent inserts 803 are respectively fixedly connected to a first connecting plate 804 and a second connecting plate 805. A first filter screen 806 is arranged inside the first connecting plate 804. An activated carbon plate 807 is arranged inside the second connecting plate 805. Multiple first springs 808 are equidistantly arranged on one side of the first connecting plate 804, and one end of the multiple first springs 808 is connected to the corresponding side of the same second connecting plate 805.

[0029] Multiple first connecting grooves 11 are equally spaced on one side of the first connecting plate 804 and one side of the second connecting plate 805. A second spring 10 is provided at one end of the inner wall of the first connecting groove 11, and the other end of the second spring 10 abuts against the outer wall of the first filter screen 806. By providing the second spring 10, the first filter screen 806 can be abutted and fixed, thereby facilitating the installation and removal of the first filter screen 806.

[0030] A sealing plate 13 is detachably installed at one end of the filter box 4. The sealing plate 13 has a groove that matches the moving plate 801 at the end near the filter box 4. A handle 12 is fixedly connected to one side of the first filter screen 806 and one side of the activated carbon plate 807. A flange 14 is fixedly connected to one side of the filter box 4. The filter box 4 is detachably installed to the exhaust pipe 15 through the flange 14. The flange 14 facilitates the installation and removal of the exhaust pipe 15. The sealing plate 13 can seal the filter box 4 to prevent exhaust gas from leaking out from the connection between the moving plate 801 and the filter box 4.

[0031] The second filtration mechanism 9 includes two slide grooves 901. The two slide grooves 901 are respectively opened inside the first connecting pipe 5 and the second connecting pipe 6. The first connecting pipe 5 and the second connecting pipe 6 are movably connected to two moving blocks 902 through the slide grooves 901. The moving blocks 902 have through holes inside, and the inner diameter of the through holes is adapted to the inner diameter of the first connecting pipe 5 and the second connecting pipe 6. By setting the second filtration mechanism 9, it can work with the first filtration mechanism 8 to perform multi-stage filtration of exhaust gas, ensuring the filtration effect of exhaust gas.

[0032] The movable plate 801 is connected to the second filter screen 905 through a through hole. A plurality of second connecting slots 903 are provided on one side of the movable plate 801. A third spring 904 is provided at one end of the inner wall of the second connecting slot 903. One end of the third spring 904 abuts against the outer wall of the second filter screen 905. The third spring 904 facilitates the installation and removal of the second filter screen 905.

[0033] One end of the movable plate 801 is fixedly connected to a limiting collar 906. A limiting rod 907 is provided inside the limiting collar 906. The outer wall of the limiting rod 907 is slidably connected to the inner wall of the sleeve 909. A fourth spring 908 is provided at one end of the inner wall of the sleeve 909. One end of the fourth spring 908 is connected to the corresponding end of the limiting rod 907. The two sleeves 909 are fixedly connected to one side of the conveying fan 1 and one side of the combustion box 2, respectively. Through the cooperation of the limiting rod 907, the limiting collar 906 and the fourth spring 908, it is convenient to remove the second filter screen 905 from the first connecting pipe 5 or the second connecting pipe 6 for replacement or cleaning, thereby avoiding the situation where the mesh of the second filter screen 905 is blocked, affecting the flow rate of the exhaust gas and reducing the filtration effect of the second filter screen 905.

[0034] Working principle:

[0035] In use, the exhaust gas is guided by the conveying fan 1, so that the exhaust gas flows through the conveying fan 1 and the first connecting pipe 5 into the combustion box 2. The exhaust gas is initially filtered by the second filter screen 905 in the first connecting pipe 5, and the combustible gas in the exhaust gas can be ignited by the combustion box 2 to achieve the effect of preliminary purification. Then, the exhaust gas flows into the spray box through the second connecting pipe 6, where it is filtered a second time by the second filter screen 905. The atomized liquid can combine with the particles in the exhaust gas, and the particles are separated from the exhaust gas by gravity, thus achieving the effect of secondary purification. Then, the exhaust gas flows into the filter box 4 through the third connecting pipe 7, where it is filtered and adsorbed by multiple first filter screens 806 and multiple activated carbon plates 807, thus purifying the exhaust gas in three stages. The purified exhaust gas is discharged to the outside through the exhaust pipe 15.

[0036] When it is necessary to replace the activated carbon plate 807 and the first filter screen 806, open the sealing plate 13, then pull out the moving plate 801 to remove multiple first filter screens 806 and multiple activated carbon plates 807 from the filter box 4. Then, remove multiple insert blocks 803 from the slots 802 to separate multiple first filter screens 806 and multiple activated carbon plates 807 from the moving plate 801. After the first filter screens 806 and activated carbon plates 807 are separated from the moving plate 801, adjacent first filter screens 806 and activated carbon plates 807 move away from each other under the action of the first spring 808, thereby increasing the distance between the first filter screens 806 and activated carbon plates 807. Then, the first filter screens 806 and activated carbon plates 807 can be removed by the handle 12. Then, replace them with new first filter screens 806 and activated carbon plates 807. Then, insert the insert blocks 803 into the slots 802, insert the moving plate 801 into the filter box 4, and seal the filter box 4 with the sealing plate 13.

[0037] When the second filter 905 needs to be replaced, press the limiting rod 907, causing it to compress and retract the fourth spring 908. Simultaneously, the limiting rod 907 will slide along the sleeve 909, allowing it to be removed from the limiting collar 906. Next, remove the moving block 902 from the first connecting pipe 5 or the second connecting pipe 6. Then, remove the second filter 905 from the moving block 902, and place a new second filter 905 inside. This process is repeated using multiple third... Spring 904 can fix the second filter screen 905. Then, the moving block 902 is inserted into the first connecting pipe 5 or the second connecting pipe 6 so that the second filter screen 905 is concentric with the first connecting pipe 5 or the second connecting pipe 6. Then, the fourth spring 908 is released so that the limiting rod 907 moves along the sleeve 909 under the action of the fourth spring 908. The limiting rod 907 can then be inserted into the limiting collar 906, thereby fixing the position of the moving block 902 and the second filter screen 905.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
