Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example

[0029] See also Figure 1-Figure 6As shown, the present embodiment provides an environmental protection device for treating medical waste, including a motor bin 1, the motor bin 1 includes a motor 11, a section of the rotating shaft of the motor 11 is fixedly connected to a motor gear 12, the teeth of the motor gear 12 are meshed with the teeth of a driven gear 13, the axis of the driven gear 13 is fixedly connected to the rotating shaft of a crushing knife 22, the crushing knife 22 is placed inside a crushing bin 2, the crushing bin 2 is fixedly connected to a combustion bin 3, the top of the combustion bin 3 is fixedly connected to four brackets, the top of the bracket is fixedly connected to a fuel bin 4, the end of the fuel bin 4 away from the crushing bin 2 is fixedly connected to a gas filter bin 5, the gas filter bin 5 includes a denitrification bin 51, a desulfurization bin 55 and a deodorization bin 57, the top of the deodorization bin 57 is provided with a through hole, the through hole is fixedly connected to an exhaust component 6.

[0030] The above working principle: when medical waste needs to be processed, first, the waste enters the crushing bin 2, and then the motor 11 is powered on to make it work. The motor 11 drives the crushing knife 22 to rotate, and the crushing knife 22 rotates to crush the waste. After the crushing work is completed, the waste enters the combustion bin 3 for combustion, and the gas generated after combustion enters the gas filter bin 5. The filtered gas is discharged into the air along the exhaust component 6, and the treatment of medical waste is completed.

[0031] In order to ensure that medical waste can be fully burned, in this embodiment, a feed partition 21 is rotatably connected to the top of the crushing bin 2, and the feed partition 21 opens and closes along the upper rotating axis toward the inside of the crushing bin 2 to prevent the splashing of debris during crushing and protect the safety of users. A plurality of blades are fixedly connected to the rotating axis surface of the crushing knife 22. A heat insulation plate 24 that opens and closes toward the inside of the combustion bin 3 is provided at the bottom of the crushing bin 2, and a slide plate 23 is provided at the bottom of the crushing bin 2, through which the crushed medical waste fragments enter the combustion bin 3.

[0032] In order to process the crushed medical waste, in this embodiment, a high-temperature spray gun 32 is fixedly connected to the top of the combustion bin 3, and the high-temperature spray gun 32 is connected to the fuel pipeline 31. The end of the fuel pipeline 31 away from the high-temperature spray gun 32 is connected to the fuel bin 4. An ash bin 36 is provided at the bottom of the combustion bin 3, and the ashes after incineration are convenient to handle. The combustion bin 3 includes a filter 33 and an oxygen inlet 34. The filter 33 is placed above the ash bin 36. The filter 33 is fixedly connected to both ends of the combustion bin 3. One end of the combustion bin 3 is provided with an oxygen inlet 34 with sufficient oxygen required for combustion. One end of the combustion bin 3 is provided with a combustion bin exhaust port 35, and the combustion bin exhaust port 35 is connected to the denitrification bin 51. High-temperature incineration allows medical waste to burn more quickly. High-temperature incineration completely kills harmful substances such as bacteria and viruses that may exist on the medical waste that endanger human health. After the incineration is completed, the combustion ashes formed do not contain harmful substances and their volume is greatly reduced.

[0033] In order to ensure that there is sufficient fuel and materials required for purification for fuel and exhaust gas treatment, in this embodiment, the fuel bin 4 includes a fuel tank 41, and the fuel pipeline 31 is connected to the fuel tank 41 in the fuel bin 4. One end of the fuel bin 4 is fixedly connected to an ammonia tank 42, so that it has sufficient fuel supply during incineration, which can ensure that the inside of the combustion bin 3 always maintains a high temperature, save fuel, and help to incinerate medical waste more fully.

[0034] In order to purify the exhaust gas after incineration, in this embodiment, an ammonia water nozzle 53 is provided on the top of the denitrification bin 51, and the ammonia water nozzle 53 is connected to the ammonia water pipeline 52. One end of the ammonia water pipeline 52 is fixedly connected to the ammonia water tank 42 in the fuel bin 4. Under the action of the catalyst, the ammonia water reacts with the NOx in the flue gas to generate nitrogen (N2) and water vapor (H2O), thereby converting NOx into harmless nitrogen. One end of the upper part of the denitrification bin 51 is provided with a denitrification bin exhaust port 54 connected to the desulfurization bin 55. The sulfur bin 55 is filled with limestone, and the SOx in the flue gas reacts with the limestone to generate calcium sulfate (CaSO4) or calcium sulfate (CaSO3), thereby removing sulfide from the flue gas. The top of the desulfurization bin 55, away from the exhaust port 54 of the denitrification bin, is provided with a desulfurization bin exhaust port 56 connected to the deodorization bin 57. The deodorization bin 57 is filled with activated carbon. The activated carbon material has a highly developed pore structure, in which micropores and mesopores can adsorb various gaseous molecules, including harmful gases and odor substances. During the adsorption process, the surface area of ​​the activated carbon material is very large, so it can capture a large number of molecules and fix them on the surface.

[0035] In order to detect whether the exhaust gas meets the emission standards, in this embodiment, the exhaust component 6 includes an exhaust pipe 61, one end of the exhaust pipe 61 is fixedly connected to a waterproof cover 62, and an exhaust gas detector 63 is provided on the lower surface of the exhaust pipe 61. One end of the exhaust gas detector 63 is fixedly connected to an air guide pipe 64. While purifying the exhaust gas, the quality of purification is also guaranteed. If the exhaust gas does not meet the emission standards, it needs to continue to participate in purification.

[0036] When the medical waste treatment and environmental protection device in this embodiment is used in practice, when it is necessary to treat medical waste, firstly, the power supply of the motor 11 is turned on, so that the motor 11 rotates to drive the rotation of the crushing knife 22, and the medical waste to be crushed is put into the crushing bin 2 from the feed partition 21. After the crushing knife 22 crushes the medical waste, the medical waste slides from the slide plate 23 into the combustion bin 3, and the high-temperature spray gun 32 incinerates the medical waste. When the medical waste is burned to ashes, when the ashes are smaller than the size of the holes in the filter screen 33, the ashes fall into the ash bin 36, and the burning gas flows into the denitrification bin 51 from the exhaust port 35 of the combustion bin. There are a large number of ammonia nozzles 53 in the denitrification bin 51, which spray the gas in all directions. Denitrification treatment, the treated gas enters the desulfurization bin 55 from the exhaust port 54 of the denitrification bin. The desulfurization bin 55 is filled with limestone. When the gas passes through the limestone, a catalytic reduction reaction occurs, so that the sulfur in the gas is absorbed. The filtered gas enters the deodorization bin 57 from the exhaust port 56 of the desulfurization bin. The deodorization bin 57 is filled with activated carbon. When the gas passes through, the activated carbon absorbs the pungent odor in the gas, so that the pungent odor in the gas is absorbed. When the exhaust gas detector 63 detects that the exhaust gas meets the emission standards, the treated gas is discharged into the air from the exhaust pipe 61. If it does not meet the emission standards, the exhaust gas is discharged into the combustion bin 3 through the air duct 64 for re-filtration, thereby completing the environmentally friendly treatment of medical waste.
