Description

Technical Field

[0001] This utility model relates to the field of medical waste incineration technology, specifically to a device for capturing and retaining particulate matter in flue gas from medical waste incineration. Background Technology

[0002] Normally, the flue gas generated from medical waste incineration is directly transported to the tail gas treatment tower through the exhaust pipe for tail gas treatment. Since a lot of particulate dust is generated during the medical waste incineration process, these particulate dust particles will enter the tail gas treatment tower along with the flue gas through the exhaust pipe. The tail gas treatment tower filters the particulate dust through its internal filter element to achieve the purpose of capture and interception.

[0003] However, due to the large amount of particulate dust generated from medical waste incineration, the filter elements in the flue gas treatment tower are severely clogged. To ensure that the flue gas velocity at the cross-section is within a reasonable range, it is necessary to increase the porosity of the filter elements or increase the frequency of filter element cleaning. High porosity leads to a decrease in filtration efficiency, while high filter element cleaning frequency results in a significant increase in water consumption and shortens the filter element's lifespan, substantially increasing the cost of flue gas treatment. Therefore, it is necessary to design a relatively low-cost device that improves the capture and retention efficiency of particulate matter in medical waste incineration flue gas to meet current needs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a device for capturing and retaining particulate matter in flue gas from medical waste incineration, which aims to improve the particulate matter capture and retention effect in flue gas from medical waste incineration at a relatively low cost.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A medical waste incineration flue gas particulate capture and interception device includes multiple diversion pipes connected to the flue gas pipe of the incinerator, the multiple diversion pipes are respectively connected to the bottom of the side wall of multiple vertically arranged dust collection chambers, the top of the dust collection chambers is equipped with a top cover, and the top covers of the multiple dust collection chambers are respectively connected to the flue gas tail pipe through a manifold.

[0007] The dust removal chamber is vertically equipped with a spiral interception plate. A crankshaft is installed inside the dust removal chamber above the spiral interception plate. The crankshaft is movably hinged to the spiral interception plate via a connecting rod. A dust removal motor that is drivenly connected to the crankshaft is installed on the outer wall of the dust removal chamber.

[0008] A dust collection hopper is fixed inside the lower part of the dust collection chamber. A spring telescopic rod is installed on the dust collection hopper. A hammer corresponding to the lower end of the spiral interception plate is fixed at the top of the spring telescopic rod.

[0009] Preferably, the vertical movement distance of the connecting rod is twice the distance between the spiral intercepting plate and the hammer.

[0010] Preferably, the bottom of the dust collection chamber is fixed with a base, and a slot is provided on the side wall of the base, into which a dust collection box is inserted.

[0011] Preferably, the shape of the dust collection box panel is adapted to the shape of the outer wall of the base, and the size of the panel is larger than the size of the slot.

[0012] Preferably, a handle is also fixed on the panel.

[0013] Preferably, both the base and the dust collection chamber are cylindrical structures, and the spiral interception plate is fitted with the dust collection chamber with a clearance.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention incorporates multiple dust collection chambers between the incinerator and the exhaust gas treatment tower. By employing diversion methods and the spiral structure of the spiral interceptor plates, the flow velocity of the flue gas is reduced. As the flue gas passes through the rough-surfaced spiral interceptor plates, it effectively promotes the settling of particulate dust, trapping a significant portion of the dust particles before the flue gas enters the exhaust gas treatment tower. The spiral interceptor plates within the dust collection chambers utilize physical dust removal, consuming only a short period of energy as the drive motor moves the plates up and down, and they vibrate against the impact hammers to clean their own particulate dust. This results in lower overall energy consumption and cost. Combined with existing exhaust gas treatment towers, this invention effectively improves the capture and interception of particulate matter in medical waste incineration flue gas, leading to cleaner and more environmentally friendly final emissions.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] like Figure 1-6 As shown, this utility model provides a technical solution: a medical waste incineration flue gas particulate capture and interception device, including multiple diversion pipes 2 connected to the flue gas pipe 1 of the incinerator, multiple diversion pipes 2 respectively connected to the bottom of the side wall of multiple vertically arranged dust collection chambers 3, the top of the dust collection chambers 3 is equipped with a top cover 4, and the top covers 4 of multiple dust collection chambers 3 are respectively connected to the flue gas tail pipe 6 through a manifold 5.

[0025] The dust collection chamber 3 has a vertically arranged spiral intercepting plate 7 inside. Both the base 14 and the dust collection chamber 3 are cylindrical structures. The spiral intercepting plate 7 is fitted with the dust collection chamber 3 with a clearance. The surface of the spiral intercepting plate 7 is rough, which helps to intercept particulate dust. A crankshaft 8 is installed inside the dust collection chamber 3 above the spiral intercepting plate 7. The crankshaft 8 is movably hinged to the spiral intercepting plate 7 through a connecting rod 9. A dust collection motor 10 is installed on the outer wall of the dust collection chamber 3 and is drivenly connected to the crankshaft 8.

[0026] A dust collection hopper 11 is fixed inside the lower part of the dust collection chamber 3. A spring telescopic rod 12 is installed on the dust collection hopper 11. A hammer 13 corresponding to the lower end of the spiral intercepting plate 7 is fixed at the top of the spring telescopic rod 12. The vertical movement distance of the connecting rod 9 is twice the distance between the spiral intercepting plate 7 and the hammer 13. When the spiral intercepting plate 7 moves up and down, it collides with the hammer 13. The vibration of the plate causes the dust particles to fall into the dust collection box 15 below.

[0027] The bottom of the dust collection chamber 3 is fixed with a base 14. A slot 1401 is provided on the side wall of the base 14. A dust collection box 15 is inserted into the slot 1401 and the base 14. The shape of the panel 1501 of the dust collection box 15 is adapted to the shape of the outer wall of the base 14, and the size of the panel 1501 is larger than the size of the slot 1401. A handle 16 is also fixed on the panel 1501.

[0028] Working principle:

[0029] The exhaust pipe 1 of the incinerator is connected to multiple dust collection chambers 3 through multiple diversion pipes 2. The manifold 5 on the top cover 4 of the dust collection chamber 3 is connected to the existing tail gas treatment tower through the exhaust tail pipe 6. Through the diversion effect of multiple dust collection chambers 3 and the spiral guide effect of the spiral interception plate 7 on the flue gas, the flue gas pressure and flow rate are reduced, which can promote the settling of particulate dust in the flue gas. At the same time, the surface structure of the spiral interception plate 7 is rough, which can better intercept particulate dust. Finally, the flue gas is further treated by the tail gas treatment tower, which can fully purify the tail gas and achieve a higher environmental protection level.

[0030] After a period of use, the dust collection chamber 3 is driven by the dust collection motor 10 to drive the crankshaft 8 and connecting rod 9 to move the spiral intercepting plate 7 up and down and collide with the hammer 13 below. The vibration generated by the impact of the spiral intercepting plate 7 causes the dust particles intercepted on the surface to fall down into the dust collection box 15 for collection and centralized treatment.
