Description

Technical Field

[0001] This invention relates to the field of medical waste treatment technology, specifically a small-scale medical and domestic waste treatment device for epidemic prevention and control. Background Technology

[0002] Medical waste refers to waste generated by medical and health institutions during medical treatment, prevention, healthcare, and other related activities that possess direct or indirect infectiousness, toxicity, or other hazards. To prevent medical waste from causing social harm and disease transmission, and to protect the environment and safeguard human health, medical waste needs to be properly disposed of. Medical waste typically contains paper, cloth, plastic, rubber, sewage, glass, etc., including items used by patients and excrement, containing viruses, bacteria, and toxic and harmful substances. Exposed piles of hospital waste can become breeding grounds for pathogens and sources of virus spread through mosquitoes, flies, and rats; therefore, the disposal of medical waste has attracted widespread attention.

[0003] The methods for handling medical waste generally include chemical treatment and incineration. Chemical treatment is usually more complicated and involves post-treatment emissions. Incineration is simple and reliable, and data shows that incineration can destroy 99.999% of organic matter.

[0004] Currently, the incineration of medical waste generally adopts the method of fixed-point incineration, which involves transporting medical waste from several hospitals to a fixed location and incinerating it using large-scale incineration equipment.

[0005] Designated incineration of medical waste has the following drawbacks: there is a risk of virus and bacteria spreading during waste transportation; if the seal is not tight or the sealed bag is damaged, it may spread through the air; the construction period of designated incineration plants is long, making it difficult to meet the needs of emergency outbreaks; larger incineration equipment not only requires large investments and high costs, but is also inconvenient to move, and cannot meet the requirements of medical institutions and other related departments that need to handle medical waste quickly, safely, conveniently and efficiently.

[0006] Centralized incineration of medical waste requires hospitals to collect, immediately package, and disinfect the waste with disinfectant. It is then transported by special vehicles to a centralized medical waste incineration plant for storage. This storage requires specialized cold storage facilities, and the storage time generally cannot exceed 48 hours. The incineration plant must process the stored waste within 48 hours to prevent bacterial growth and infection. Because medical waste is sprayed with disinfectant before incineration, it is difficult for it to reach 900℃ during combustion, making it not only difficult to burn but also prone to producing carcinogenic gases.

[0036] Please see Figure 1-4 The present invention provides an embodiment of a small-scale medical and domestic waste treatment device specifically for epidemic prevention and control, comprising a furnace body 1, and a hoist 5 for lifting medical waste into the furnace body 1 on one side of the furnace body 1; the furnace body 1 is provided with a partition 17, which divides the interior of the furnace body 1 into a water storage tank 15 and a combustion tank 18; the water storage tank 15 can convert the chemical energy in the combustion tank 18 into thermal energy, thereby realizing energy conversion;

[0037] The water storage tank 15 is sealed by an end cap 12, and a fan compartment 11 for mounting a fan is provided on the end cap 12. The lower surface of the end cap 12 is provided with a conductor 16 for transferring heat from the inside of the water storage tank 15 to the fan compartment 11. The fan compartment 11 is provided, and a fan is installed in the fan compartment 11 to blow the heat energy transferred from the water storage tank 15 into the elevator 5. Therefore, the device can perform preliminary drying of medical waste in the elevator 5. Thus, the device can dry medical waste without the need for other special drying equipment, achieving comprehensive energy utilization while simplifying the processing technology of existing medical waste treatment equipment.

[0038] The combustion chamber 18 is connected to the discharge port 7 of the elevator 5 via a feed pipe 9. The elevator 5 is connected to the fan chamber 11 via a pipe 8. The end of the pipe 8 away from the fan chamber 11 is installed at the bottom of the elevator 5. Since the pipe 8 blows air from bottom to top, the medical waste is continuously dried during the lifting process. In addition, the pipe 8 has a diameter of 20 cm, which simultaneously provides the large air volume generated by the axial flow fan in the fan chamber 11 to the inside of the elevator 5. The large air volume, combined with the heat energy generated by the water storage tank 15, removes moisture from the medical waste.

[0039] The lower end of the furnace body 1 is also provided with an ash storage area 2 for containing ash. Above the ash storage area 2 is a flamethrower 20. The lower end of the flamethrower 20 is connected to an external air source through an air inlet pipe 14 passing through the ash storage area 2. The flamethrower 20 can spray flames to burn the medical waste falling into the combustion chamber 18. The flames sprayed by the flamethrower 20 can briefly suspend the waste flowing into the combustion chamber 18, further drying the waste. While drying, once the waste reaches its melting point, it can burn instantly, making the combustion of the waste more complete.

[0040] The ash storage area 2 is hemispherical, and a discharge pipe 21 is provided at the lowest end of the ash storage area 2. A sealing cap 22 is threadedly connected to the discharge pipe 21. The hemispherical ash storage area 2 can both accumulate ash and facilitate the ash to flow out from the discharge pipe 21. When the discharge pipe 21 is not connected to the ash conveying equipment, it can be sealed with the sealing cap 22 to ensure that the ash is located in the ash storage area 2. At the same time, the sealing cap 22 is threadedly connected to the discharge pipe 21, so it is also convenient for the installation and disassembly of the two. When there is insufficient air inside the furnace body 1, the sealing cap 22 can be removed to provide sufficient air inside the furnace body 1.

[0041] The flamethrower 20 has an internal cavity 31, the cross-section of which is an inverted trapezoid. Multiple fixing holes 30 for mounting the nozzle are provided on the upper surface of the flamethrower 20, each with internal threads, and arranged in a circumferential array on the upper surface of the flamethrower 20. The cavity 31 allows combustible gas to accumulate within it, thus ensuring a stable gas supply to the flamethrower 20. In short, it stabilizes the gas pressure and solves the problem of uneven gas ejection.

[0042] The ratio of the diameter of the flamethrower 20 to the inner diameter of the furnace body 1 is 1:1.5. This ratio ensures that dust falls while preventing the flamethrower 20 from contacting the inner wall of the furnace body 1, thus avoiding overheating of the furnace body 1. Inside the furnace body 1, above the flamethrower 20, a furnace plate 19 is also provided. The distance between the lower surface of the furnace plate 19 and the upper surface of the flamethrower 20 is 15 cm. This 15 cm gap ensures that the outer flame of the flame passes through the furnace plate 19 to burn the waste, allowing the waste to enter a short-circuitous path. When the suspension function is activated, it will not cause excessive dust or garbage to be suspended in the combustion chamber 18; and multiple round holes 4 for flame to pass through are provided on the furnace plate 19; in addition, the furnace plate 19 is designed to both prevent garbage from entering the ash storage area 2 and ensure that the ash falls without obstruction; when the garbage enters before reaching the melting point and falls onto the furnace plate 19, the flame sprayed by the flame jet 20 can blow it up again, and so on, so that the garbage is burned off after rolling on the furnace plate 19 multiple times, thus further improving the garbage processing efficiency;

[0043] The furnace body 1 is also equipped with an observation hole 24 and a flue pipe 13. The observation hole 24 is located above the furnace plate 19, and the flue pipe 13 is located above the combustion chamber 18. The observation hole 24 is designed to allow personnel to easily observe the internal condition of the furnace body 1. If any plastic or hardened ash adheres to the furnace plate 19, it can be quickly removed. At the same time, when the device uses coal to burn waste, the observation hole 24 can also be used as a coal loading port. In this case, the burner 20 can continue to replenish the fuel gas and also act as an air input device.

[0044] Through the above scheme, the device simplifies the structure of existing waste treatment devices while achieving comprehensive energy utilization and thorough waste treatment. It also enables the device to burn either coal or natural gas, or a combination of both, greatly extending the device's versatility.

[0045] In addition, the internal structure of furnace body 1 is simple, which is convenient for production and also helps to reduce the user's operating costs; it is especially suitable for the need to quickly set up waste treatment facilities during the epidemic. Therefore, it can be easily transferred to the medical department for on-site incineration of medical waste according to the usage requirements, avoiding the transportation of medical waste and reducing the investment and operating costs of medical waste treatment.

[0046] To facilitate the installation of fans, such as axial fans, the fan housing 11 includes a base plate 26 communicating with the conductor 16, and a cover plate 25 is provided above the base plate 26. The cover plate 25 is folded together from the side facing the base plate 26 to the side facing away from the base plate 26, forming a mounting hole 27 that communicates with the pipe 8. By separating the base plate 26 from the cover plate 25, the axial fan is vertically installed in the fan housing 11 with the air outlet facing the mounting hole 27. The folded mounting hole 27 allows the airflow to be discharged more concentratedly from the mounting hole 27, thus enabling the airflow to be transported to the elevator 5 at a high flow rate through the pipe 8, and removing the waste and moisture in the elevator 5 as quickly as possible.

[0047] To prevent the device from burning dry, the furnace body 1 is also equipped with a level pipe 10 for displaying the water level inside the water storage tank 15. The level pipe 10 also makes it convenient for personnel to replenish the water storage tank 15 with water in a timely manner.

[0048] The end cap 12 is also provided with an exhaust valve 28 for venting hot air from the inside of the water storage tank 15 and a water inlet 29 for adding water to the water storage tank 15. The exhaust valve 28 can release pressure when the internal pressure of the water storage tank 15 exceeds a certain value, thereby reducing the pressure of the water storage tank 15. The water inlet 29 facilitates the addition of water.

[0049] To facilitate heat concentration and rapid transfer, the number of conductors 16 is at least three, and they are arranged in an equidistant array on the end cap 12; the conductors 16 are made of brass.

[0050] To facilitate the maintenance of the device, the end cap 12 and the water storage tank 15 are threaded together, and a sealing ring is provided at the connection. The ash storage area 2 and the furnace body 1 are also threaded together. In addition, the threaded connection facilitates the replacement of each component. In particular, the three components are connected by a movable connection, which allows the three components to be manufactured independently, reducing the manufacturing difficulty and facilitating the replacement of related components.

[0051] Since the observation hole 24 is a cylindrical tube and a sealing plate 23 is connected to the observation hole 24 by a shaft pin, it is convenient to observe the inside of the furnace body 1, and at the same time, it prevents the heat inside the furnace body 1 from being lost.

[0052] The upper end face of the elevator 5 is provided with an exhaust port 6 to facilitate airflow. The inner wall of the exhaust port 6 is provided with threads, which allows the exhaust port 6 to be connected to purification equipment such as a flue gas treatment device to prevent the overflow of harmful gases. Furthermore, a feed inlet 3 is provided below the elevator 5 to receive crushed medical waste. The feed inlet 3 is located at the bottom of the elevator 5 to facilitate the entry of medical waste.

[0053] Since the combustion gases from medical waste can be treated before being emitted, the exhaust port 6 and exhaust valve 28 of the treatment device in this application can be connected to a corresponding flue gas treatment device as needed; the flue gas treatment device can be any product in the prior art; the feature of this application is that it provides a small-scale waste treatment combustion device with drying function to meet the needs of quickly establishing waste incineration sites during the epidemic prevention and control period.

[0054] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
