Description

Technical Field

[0001] This article relates to but is not limited to the field of medical waste treatment, and in particular to a reaction device and operation method of medical waste treatment equipment. Background Art

[0002] In some technologies, medical waste is centrally treated, which can be divided into five major links: generation, collection, transportation, storage and treatment. The treatment method is mainly high-temperature incineration, supplemented by high-temperature cooking, chemical disinfection, microwave disinfection and other methods. High-temperature incineration includes complete combustion and oxygen-deficient combustion. By building a large medical waste disposal plant, medical waste within a certain range is collected and then centrally incinerated. The furnace types used in high-temperature incineration include AB pyrolysis incinerator, vertical rotary pyrolysis incinerator, and rotary incinerator. However, the high-temperature incineration method has the problem of insufficient and incomplete treatment. Summary of the invention

[0017] Figure 2 This is a flow chart of the operating method of the reaction device of the medical waste treatment equipment in the embodiment of the present application. DETAILED DESCRIPTION

[0018] The present application describes multiple embodiments, but the description is exemplary rather than restrictive, and it is obvious to those skilled in the art that there may be more embodiments and implementations within the scope of the embodiments described in the present application. Although many possible feature combinations are shown in the drawings and discussed in the specific embodiments, many other combinations of the disclosed features are also possible. Unless specifically limited, any feature or element of any embodiment may be used in combination with any other feature or element in any other embodiment, or may replace any other feature or element in any other embodiment.

Any features or elements of any embodiment may also be combined with features or elements from other invention schemes to form another unique invention scheme defined by the claims.

Therefore, except for the limitations made according to the attached claims and their equivalents, the embodiments are not subject to other restrictions. In addition, various modifications and changes may be made within the scope of protection of the attached claims.

[0020] In addition, when describing representative embodiments, the specification may have presented the method and / or process as a specific sequence of steps. However, to the extent that the method or process does not rely on the specific order of the steps described herein, the method or process should not be limited to the steps of the specific order described. As will be understood by those of ordinary skill in the art, other sequences of steps are also possible. Therefore, the specific sequence of the steps set forth in the specification should not be interpreted as a limitation to the claims. In addition, the claims for the method and / or process should not be limited to the steps of performing them in the order written, and those skilled in the art can easily understand that these sequences can be changed and still remain within the spirit and scope of the embodiments of the present application.

[0021] The inventors of the present application have keenly discovered in practice that although the high-temperature incineration method has a large disposal volume and obvious reduction effect, it has the problems of high construction cost, difficulty in project implementation, serious environmental pollution, and the need for long-term heat engine. The equipment required for treatment methods such as high-temperature cooking, chemical disinfection, and microwave disinfection is relatively small and easy to move, and can be used for on-site treatment of medical waste, which can avoid leakage of pollution sources to a certain extent. However, these methods mainly target pathogens to inactivate them and achieve the purpose of harmless treatment, but do not have a reduction effect, and these methods only reduce the danger of pathogen residues, and do not completely kill bacteria and viruses.

[0022] The inventors of the present application have also found in practice that in some technologies, medical waste treatment equipment is only equipped with one reaction device, that is, the filling and subsequent treatment steps of medical waste need to be completed in one cavity. The technology of using a single cavity to treat medical waste has the following disadvantages:

[0023] 1. Since there is only one reaction device, it is necessary to complete the filling before starting the heat engine, and after the treatment is completed, it is necessary to wait for the reaction device to cool down to a certain temperature before filling again. The processing time required is long, and the time and energy spent on the heat engine and cooling are high, which is not conducive to energy saving and environmental protection;

[0024] Second, all medical waste is treated in one reaction device, which may lead to incomplete and insufficient treatment of medical waste;

[0025] 3. An additional heat source is required to maintain the high temperature environment in the reaction device;

[0026] Fourth, using a cavity for treatment requires a large amount of air to be introduced all the time to ensure complete combustion. The large gas flow will cause the flue gas to contain a large amount of particulate matter, which will not only cause environmental pollution, but also may damage the subsequent exhaust treatment equipment if it is installed later.

[0027] like Figure 1 As shown, the embodiment of the present application provides a reaction device of a medical waste treatment device, comprising:

[0028] The gasification reaction device 100 is configured to receive medical waste and perform gasification treatment or gasification and combustion treatment on the medical waste;

[0029] The recombination reaction device 200 is connected to the gasification reaction device 100 and is configured to crack and burn the gasified medical waste.

[0030] The medical waste treatment equipment in the embodiment of the present application is provided with two reaction devices, and the gasification reaction device 100 is first used to gasify or gasify and burn the medical waste; then the recombination reaction device 200 is used to crack and burn the gasified medical waste, that is, the medical waste is pyrolyzed and gasified in the gasification reaction device 100 to produce combustible gas or macromolecular particles, and the macromolecules that are difficult to crack are cracked into small molecules in the recombination reaction device 200, and the cracked small molecules and combustible gas are burned. The volume of the recombination reaction device 200 can be set larger than the volume of the gasification reaction device 100, which is helpful for fully reacting the gasified medical waste, but the embodiment of the present application does not limit this. The reaction device of the medical waste treatment equipment is combined with the pyrolysis and incineration technology to achieve a better treatment effect.

[0031] Figure 1 The gasification reaction device 100 and the recombination reaction device 200 are two separately arranged cavities, and the gasification reaction device 100 and the recombination reaction device 200 can also be integrated and processed. The embodiment of the present application does not limit the number, shape, connection form and spatial position distribution of the gasification reaction device 100 and the recombination reaction device 200.

[0032] In the embodiment of the present application, the two reaction devices are used to organically divide the medical waste treatment process into two reaction steps: a gasification (or gasification and combustion) step, and a cracking and combustion step, so that the reaction of the medical waste is more sufficient and thorough; and, since the two reaction devices can be controlled separately, the filling can be started after the gasification reaction device 100 completes the reaction, without waiting for all the treatment steps to be completed, which helps to shorten the overall treatment time, save costs, and is more energy-saving and environmentally friendly; the recombination reaction device 200 can crack and burn the gasified medical waste, which helps to reduce the solid particles in the flue gas. The two reaction devices are used for separate treatment, which slows down the flow of the gas introduced into the reaction device to a certain extent, and can reduce the solid particles contained in the flue gas discharged from the recombination reaction device 200, which is more environmentally friendly and helps to maintain related equipment, thereby extending the service life of the equipment.

[0033] The reaction device of the medical waste treatment equipment in the embodiment of the present application can also be used to treat various solid wastes and pollutants, such as: domestic garbage, industrial waste, plastic waste, pharmaceutical residues, etc.

[0034] In an exemplary embodiment, the reaction device of the medical waste treatment equipment further includes:

[0035] A plasma generating device, configured to emit plasma into the gasification reaction device 100 and the recombination reaction device 200;

[0036] The gasification reaction device 100 uses the internal plasma to perform gasification or gasification and combustion treatment on the medical waste; the recombination reaction device 200 uses the internal plasma to crack and burn the gasified medical waste. In the embodiment of the present application, the use of plasma to treat medical waste has the following advantages:

[0037] Medical waste can be treated only by electricity, without fuel supply, safe and environmentally friendly; it solves the problems of high construction cost, difficulty in project implementation, serious environmental pollution and long-term warm-up of high-temperature incineration method;

[0038] Plasma can reach high temperature instantly without long-term heat-up process; it also does not need to use additional heat source to maintain the high temperature environment in the reaction device; it has longer service life;

[0039] The plasma generator is used as the energy source, which can be shut down at any time and can realize the miniaturization of the processing equipment. It has the advantages of flexible use, convenience and high efficiency, which is convenient for the distributed treatment of medical waste and makes the treatment of medical waste more flexible.

[0040] Microwave plasma has the characteristics of high energy and high heat, and can effectively treat the difficult-to-degrade and hazardous components in medical waste. It can effectively degrade pollutants and inactivate pathogens, achieve the purpose of reduction, and have better treatment effects.

[0041] In an exemplary embodiment, the plasma generating device is configured as a microwave plasma generating device 5, and a plurality of microwave plasma generating devices 5 are respectively arranged around the gasification reaction device 100 and the recombination reaction device 200;

[0042] The microwave plasma generating device 5 comprises a microwave plasma torch pipeline 4 and a microwave power supply 6 .

[0043] Microwave plasma has the characteristics of instantaneous high temperature, a large number of high-energy particles, and no need for electrodes. It is easy to deploy and use.

[0044] like Figure 1 As shown, several microwave plasma devices 5 are respectively arranged around the gasification reaction device 100 and the recombination reaction device 200. Each microwave plasma generating device 5 is equipped with a microwave plasma torch pipe 4 and a microwave power supply 6. The generated plasma can enter the gasification reaction chamber 100 and the recombination reaction chamber 200 through the plasma torch pipe 4 to achieve the treatment of medical waste.

[0045] In an exemplary embodiment, 2-8 microwave plasma generators can be arranged around the gasification reaction device 100, and 2-6 microwave plasma generators 5 can be arranged around the recombination reaction device 200. Each microwave plasma generator 5 can select a microwave plasma source with a power of 0.8-3kW as required. The number and power of the plasma generator can be set as required, and the embodiment of the present application does not limit this.

[0046] The microwave power supply 6 can control the switch of the corresponding microwave plasma generator 5. The position and form of the microwave power supply 6 can be set as needed, so as to control the number of microwave plasma generators 5 around the gasification reaction chamber 100 and the recombination reaction chamber 200 to control the number and intensity of plasma inside the gasification reaction device 100 and the recombination reaction device 200; the number and intensity of plasma can also be controlled by adjusting the power of the microwave plasma generator 5. The microwave plasma torch pipeline 4 at the gasification reaction device 100 can be set at a position close to the medical waste, and the microwave plasma torch pipeline 4 at the recombination reaction device 200 can be set to be distributed according to the airflow direction in the recombination reaction device 200. This setting helps to improve the treatment effect and efficiency of medical waste. However, the embodiment of the present application does not limit the spatial position distribution of the microwave plasma generator 5 in the gasification reaction device 100 and the recombination reaction device 200, how to adjust the number and intensity of plasma inside the gasification reaction device 100 and the recombination reaction device 200, and the position and form of the microwave power supply 6.

[0047] In the gasification reaction device 100, the core temperature of the microwave plasma torch can reach 2000-8000 degrees. After killing the pathogens, the extremely high temperature can quickly melt the metal and glass materials to form a vitrified state. In this process, the volume of metal and glass waste will be greatly reduced, which is convenient for subsequent treatment after cooling; and for waste such as plastics and drug residues, microwave plasma contains a large number of high-energy particles and rays, which can directly bombard the chemical bonds of molecules, causing them to break into small molecular compounds, or pyrolyze into gas under the high temperature of microwave plasma to form a large amount of combustible gas. In addition, the gasification reaction device 100 does not need to be preheated, it can be used immediately after it is turned on, and can be turned on and off at any time according to actual needs.

[0048] After a short preheating, the temperature of the recombination reaction device 200 can rise to about 800 degrees. By utilizing the high-energy particle bombardment of microwave plasma, macromolecular substances that are difficult to crack, such as benzene rings, dioxins and other toxic and harmful substances, can be directly cracked into small molecular substances. And under the action of the microwave plasma torch, they are burned cleanly in an atmosphere of sufficient oxygen, and the heat generated by the combustion can be used to maintain the high temperature environment required by the recombination reaction device 200. Therefore, the recombination reaction device 200 does not need to use an additional heat source to maintain the high temperature environment in the reaction device.

[0049] The electron energy contained in a single microwave plasma is about 1-3eV. The decomposition of organic matter by plasma can be simply expressed as follows:

[0050] C m H n O s→aCO+bCO2+pH2+qCH4+xH2O

[0051] In an exemplary embodiment, the gasification reaction device 100 includes:

[0052] A feeding port 1 is configured to provide a passage for feeding medical waste into the gasification reaction device 100 after being opened;

[0053] Gasification space 3, configured to perform gasification treatment or gasification and combustion treatment on medical waste;

[0054] A feeding device 2, located between the feeding port 1 and the gasification space 3, is configured to place the medical waste fed into the gasification space 3;

[0055] The feeding partition 13 is configured to provide a passage for medical waste to enter the gasification space 3 from the feeding device 2 after being opened.

[0056] In the embodiment of the present application, a feeding partition 13 is provided between the feeding device 2 and the gasification space 3, so that the feeding and gasification treatment processes can be separated. After the feeding enters the gasification space 3, the feeding partition 13 is closed, and the medical waste fed can react in the gasification space 3. At this time, since the feeding partition 13 is closed, the feeding device 2 is isolated from the gasification space 3, and the feeding device 2 can continue to be fed from the feeding port 1. Therefore, after the medical waste in the gasification space 3 is processed, the next batch of feeding can be directly processed, thereby realizing continuous feeding and gasification treatment, and the processing process is more convenient and quick.

[0057] In an exemplary embodiment, the gasification reaction device 100 further includes:

[0058] A slag channel 10 connected to the gasification space 3 and configured to allow the processed slag to be discharged from the gasification space 3;

[0059] The slag container 8 is connected to the slag channel 10 and is configured to collect the processed slag.

[0060] In the embodiment of the present application, after the medical waste is processed in the gasification space 3, the generated slag can enter the slag container 8 through the slag channel 10, so as to facilitate the subsequent processing of the slag.

[0061] By using the reaction device of the medical waste treatment equipment in the embodiment of the present application, after the treatment is completed, the reduction of medical waste can reach more than 90%, the amount of slag produced is small, and the remaining slag after the treatment is mainly carbon elements, does not contain any substances harmful to the environment or organisms, can be directly buried and naturally degraded by the environment, and the residues after the metal and glass are melted and cooled can be further processed as needed. The miniaturized medical waste treatment equipment in the embodiment of the present application can be flexibly set at the required location to treat medical waste at any time, avoiding the cost and pollution problems caused by transportation and storage during centralized treatment.

[0062] In an exemplary embodiment, the reaction device of the medical waste treatment equipment further includes:

[0063] A plurality of air distribution ports 11 and 15 respectively located in the gasification reaction device 100 and the reforming reaction device 200 are configured to distribute gas to the gasification reaction device 100 and the reforming reaction device 200 respectively;

[0064] The heat insulation layer 9 is respectively located outside the gasification reaction device 100 and the recombination reaction device 200;

[0065] A flue gas outlet 14 is provided on the recombination reaction device.

[0066] like Figure 1 As shown, in the embodiment of the present application, an air distribution port 11 is set on the gasification reaction device 100, and an air distribution port 15 is set on the recombination reaction device 200. A blower and other equipment can be used to distribute gas to the gasification reaction device 100 and the recombination reaction device 200 respectively to support the processing processes performed by the two. Figure 1 What is shown in the figure is an exemplary implementation mode, and the embodiment of the present application does not limit the location and number of the air distribution ports.

[0067] In practical applications, the reaction occurring in the gasification reaction device 100 can be controlled by controlling the gas distributed to the gasification reaction device 100, for example, an inert gas can be introduced into the gasification reaction device 100 so that only a gasification reaction occurs in the gasification reaction device 100; or an oxygen-containing gas can be introduced into the gasification reaction device 100 so that a gasification and combustion reaction occurs in the gasification reaction device 100. The type of gas distributed to the gasification reaction device 100 and the gas flow rate can be selected and adjusted as needed, and the embodiments of the present application do not limit this.

[0068] In the embodiment of the present application, the gasification reaction device 100 and the recombination reaction device 200 are both wrapped by the heat insulation layer 9 to reduce the heat loss inside the reaction device. By providing the heat insulation layer 9, the temperature of the outer surface of the device can be lower than 50 degrees, which is helpful for maintaining the heat inside the device and the safe operation of the device.

[0069] A flue gas outlet 14 is provided on the recombination reaction device 200, and an induced draft fan may also be provided at the flue gas outlet 14. A gas channel 12 is provided between the gasification reaction device 100 and the recombination reaction device 200. When the gas channel 12 is opened, the gasification reaction device 100 can be connected with the recombination reaction device 200. Under the action of the air distribution of the gasification reaction device 100 and the induced draft fan of the flue gas outlet 14, the gas in the gasification reaction device 100 moves to the recombination reaction device 200 through the gas channel 12 and is processed by the recombination reaction device 200.

[0070] In an exemplary embodiment, the gas residence time in the gasification reaction device 100 and the recombination reaction device 200 can be controlled by the cooperation of the blower and the induced draft fan, and after the filling is completed, a negative pressure state can be formed and maintained in the gasification reaction device 100 and the recombination reaction device 200. In this negative pressure state, it can be ensured that the gas in the reaction device will not escape from the device to avoid pollution, and it can also avoid accidents such as explosions to ensure safety. The range of negative pressure can be set as needed, such as between -10Pa and -500Pa.

[0071] The reaction device of the medical waste treatment equipment in the embodiment of the present application is used, and the gas discharged from the smoke outlet 14 has a carbon monoxide content of 50 mg / m 3 The following can meet the exhaust gas emission requirements; the gas discharged from the flue gas outlet 14 can also be further subjected to exhaust gas treatment to make the exhaust gas treatment more thorough, and the embodiments of the present application do not limit this.

[0072] The reaction device of the waste treatment equipment in the embodiment of the present application can also achieve good treatment effects when used to treat various solid wastes and pollutants.

[0090] The operating method of the reaction device of the medical waste treatment equipment in the embodiment of the present application is applied to the reaction device of the medical waste treatment equipment. The function and effect of each step can be found in the description of the above-mentioned reaction device, which will not be repeated here.

[0092] Example 1

[0093] S1. Turn on the microwave plasma generator 5 for a short heat engine;

[0094] The heat engine mentioned here refers to the preheating of the recombination reaction device 200.

During actual operation, it is also necessary to keep the temperature in the recombination reaction device 200 in the range of 800-1000 degrees. In actual operation, the source of maintaining the temperature in the recombination reaction device 200 is mainly the combustion of the pyrolysis gas in the recombination reaction device 200; the gasification reaction device 100 does not need to be preheated, and there is no requirement for the temperature of the reaction.

Then, the medical waste is pyrolyzed and gasified, and the generated pyrolysis gas is fully burned in the recombination reaction device 200, and the tail gas is discharged from the flue gas outlet 14. During the reaction process, the treatment process can be regulated by the air distribution ports 11 and 15, including: maintaining the negative pressure state in the reaction device, adjusting the distribution gas and the distribution gas volume, etc.;

[0098] After closing the feeding baffle 13 in the gasification reaction device 100, the feeding operation can continue.

[0099] S5. After the medical waste is processed, the slag channel 10 is opened and the slag falls into the slag container 8.
