Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology for vehicle power units, and in particular to a dual-core series CO ablation chamber structure. Background Technology

[0002] Currently, explosion-proof diesel engine exhaust purification devices for underground working conditions have emerged on the market. These devices primarily absorb CO components in the exhaust gas. They are characterized by strong adaptability, small size, and outstanding treatment effect, without altering the structure of the original explosion-proof transport vehicle. They also offer advantages such as convenient and simple installation and low maintenance costs.

[0003] However, existing CO ablation boxes are tank-type structures, which result in a large installation space requirement. Furthermore, because they operate as an integrated unit with the explosion-proof diesel engine, their installation on the monorail of the explosion-proof diesel engine affects traffic flow within the tunnel, thus presenting certain limitations.

[0004] Furthermore, because the filter element is usually designed with a through-channel in the middle, the contact area between the filter element and the exhaust gas is limited after adopting the canister structure, resulting in insufficient absorption of CO.

[0005] Therefore, there is an urgent need for a dual-core series CO ablation chamber structure that is small in size, does not change the original explosion-proof transport vehicle structure, and can improve the filtration effect. Utility Model Content

[0006] This invention provides a dual-core series CO ablation chamber structure that can reduce volume, maintain the original explosion-proof transport vehicle structure, and achieve a significant CO absorption and conversion effect.

[0007] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0008] A dual-core series CO ablation chamber structure includes:

[0009] Box 1 has a first opening on one side. Box 1 has a double-layer structure and an air inlet on the upper surface.

[0010] Box 2 has a second opening on its side. Box 2 has a double-layer structure. The upper surface of box 2 has an air vent. The second opening is sealed and fixedly connected to the first opening. A middle partition is provided between the first opening and the second opening. The middle partition is fixedly connected to box 1 or box 2.

[0011] The upper bracket has at least two upper brackets, which are fixed to the upper end of the interior of box one and box two respectively. The edges of the upper brackets are fixedly connected to the inner side wall of box one or box two respectively. The upper brackets are all hollow structures and each upper bracket is equipped with an upper filter element. The upper filter element is equipped with several upper filter air channels.

[0012] Bottom bracket, the bottom bracket is fixed inside the lower part of box one and box two. The upper surface of the bottom bracket is provided with a downwardly recessed connecting air passage. There is a gap between the lower end of the middle partition and the bottom bracket. The bottom bracket is provided with a lower filter element, and the lower filter element is provided with several lower filter air passages.

[0013] The upper filter duct is connected to the lower filter duct.

[0014] The basic design principle and beneficial effects are as follows: Both housing one and housing two are double-layered structures, with coolant flowing between them to cool the piping and housing, effectively reducing exhaust gas temperature and minimizing the risk of thermal damage. Housing one has an air inlet on its upper surface to receive engine exhaust gas; housing two has an air outlet on its upper surface to discharge treated exhaust gas. The upper and lower brackets are fixed to the upper and bottom of housings one and two, respectively, and both have hollow structures containing filter elements. The upper bracket houses the upper filter element, and the lower bracket houses the lower filter element; both have filter ducts for effective exhaust gas filtration. The separate filter element design facilitates installation and maintenance, improving equipment lifespan and maintenance efficiency. The upper and lower filter ducts are connected, ensuring continuous and effective filtration of exhaust gas as it passes through the housing, thus improving filtration efficiency.

[0015] A central partition separates chamber one and chamber two, ensuring that exhaust gas fully passes through the filter element in chamber one before entering chamber two from the bottom bracket, and then passes through the filter element in chamber two before being discharged. This design allows the exhaust gas to fully contact the filter element as it passes through the chambers, improving CO dissolution efficiency.

[0016] This utility model adopts a split-type structural design, which greatly reduces the installation space occupied compared to the traditional tank-type structure, making it particularly suitable for underground environments with narrow tunnel cross-sections. The split design makes filter element replacement and maintenance more convenient, eliminating the need to replace the entire exhaust pipe and reducing maintenance costs. Through a dual-core series filtration design, the CO filtration and absorption efficiency reaches over 85%, effectively reducing the CO concentration in the underground working environment. The compact box structure and small size facilitate installation in confined spaces without affecting passage within the tunnel.

[0017] In summary, this utility model achieves the goals of reducing volume, not altering the original explosion-proof transport vehicle structure, and significantly improving CO absorption and conversion.

[0018] Furthermore, both housing 1 and housing 2 are equipped with a central bracket, which is a hollow structure. The central bracket is fixedly connected to housing 1 and housing 2 respectively, and the lower filter element is located inside the central bracket.

[0019] Furthermore, a copper pad is provided between the second opening and the first opening, and an extension block is provided at the edge of the second opening and the first opening.

A sealing hole is provided at the position where the extension block on the first box and the extension block on the second box face each other. The copper pad is located between the extension block on the first box and the extension block on the second box.

[0020] Furthermore, both the first and second housings are equipped with cooling water inlet pipes and cooling water outlet pipes on their sides, which are respectively connected to the cavities within the double-layer structure of the first and second housings.

[0021] Furthermore, an air inlet flange is provided at the air inlet, and the air inlet flange is fixedly connected to the housing. The air inlet flange is provided with several first threaded holes.

[0022] Furthermore, an air outlet flange is provided at the air outlet, and the air outlet flange is fixedly connected to the housing. The air outlet flange is provided with several second threaded holes.

[0024] Furthermore, an exhaust pipe 2 is provided at the outlet flange, and the exhaust pipe 2 is fixedly connected to the outlet flange.

[0025] Furthermore, both exhaust pipe one and exhaust pipe two are double-layered structures, with coolant inlet pipe and coolant outlet pipe provided on the outer layer of both exhaust pipe one and exhaust pipe two. Attached Figure Description

Detailed Implementation

[0030] The following detailed description illustrates the specific implementation method:

[0031] A dual-core series CO ablation chamber structure (such as...) Figure 1, Figure 2 (as shown), including:

[0032] Box 1 has a first opening on one side. Box 1 has a double-layer structure and an air inlet on the upper surface.

[0033] Box 2 has a second opening on its side. Box 2 has a double-layer structure. The upper surface of box 2 has an air vent. The second opening is sealed and fixedly connected to the first opening (the specific connection relationship is as follows: a copper gasket is provided between the second opening and the first opening, and an extension block is provided at the edge of the second opening and the first opening. The extension block is fixedly connected to box 1 and box 2 respectively. Sealing holes are provided on the front of the extension block on box 1 and the extension block on box 2. The copper gasket is located between the extension block on box 1 and the extension block on box 2). A middle partition 8 is provided between the first opening and the second opening.

[0034] Upper bracket 5, the number of upper brackets 5 is two (e.g. Figure 3 As shown), the upper bracket 5 is welded and fixed to the upper end of the inside of box 1 and box 2 respectively. The edge of the upper bracket 5 is welded to the inner side wall of box 1 or box 2 respectively. The upper bracket 5 is hollow. The upper bracket 5 is equipped with an upper filter element 9. The upper filter element 9 is fixed with the upper bracket 5 by interference fit. The upper filter element 9 is provided with several (depending on the type of filter element) upper filter air passages.

[0035] Bottom bracket 7 is fixed inside the lower part of housing 1 and housing 2. The upper surface of bottom bracket 7 has a downwardly recessed connecting air passage. There is a gap between the lower end of the middle partition 8 and bottom bracket 7. Bottom bracket 7 is provided with a lower filter element 10, and the lower filter element 10 is provided with several lower filter air passages. The upper filter air passages are connected to the lower filter air passages. Both housing 1 and housing 2 are provided with a middle bracket 6. The middle bracket 6 is a hollow structure and is welded to housing 1 and housing 2 respectively. The lower filter element 10 is located in the middle bracket 6. The middle bracket 6 can better fix the lower filter element 10 and avoid misalignment of the upper filter air passages and lower filter air passages, which would affect the effect.

[0036] The sides of both housing 1 and housing 2 are equipped with cooling water inlet pipes 11 and cooling water outlet pipes, which are respectively connected to the cavities within the double-layer structure of housing 1 and housing 2. An air inlet flange is provided at the air inlet, welded to housing 1, and has six first threaded holes. An air outlet flange is provided at the air outlet, welded to housing 2, and has six second threaded holes. An exhaust pipe 3 is provided at the air inlet flange, and is bolted to the air inlet flange. An exhaust pipe 4 is provided at the air outlet flange, and is bolted to the air outlet flange. Both exhaust pipes 3 and 4 are double-layer structures, with coolant inlet pipes 12 and coolant outlet pipes on their outer layers.

[0037] In practical use: One side of the housing 1 has a first opening, and its upper surface has an air inlet. Housing 1 has a double-layer structure, designed to contain coolant to reduce exhaust gas temperature.

[0038] Box 2 has a second opening on its side and an air vent on its upper surface. Box 2 is also a double-layer structure. The second opening and the first opening are sealed together by a sealing gasket (such as a copper gasket) and an extension block. The extension block is connected to both box 1 and box 2. The extension blocks on box 1 and box 2 have sealing holes on their front faces, with the copper gasket located between them.

[0039] There are two upper brackets 5, which are installed at the upper end of the first box 1 and the second box 2 respectively. Their edges are connected to the inner side wall of the box. Both are hollow structures and contain upper filter elements 9. The upper filter elements 9 are provided with several upper filter air channels.

[0040] Both housing 1 and housing 2 are equipped with a central bracket 6, which is a hollow structure connected to the housing. The lower filter element 10 is located inside the central bracket 6. A bottom bracket 7 is fixed to the lower part of housing 1 and housing 2, and its upper surface has a downwardly recessed connecting air passage. A gap is left between the lower end of the central partition 8 and the bottom bracket 7. The bottom bracket 7 is equipped with the lower filter element 10, which has several lower filter air passages. The upper filter air passages are connected to the lower filter air passages to achieve effective filtration of the exhaust gas.

[0041] Both the first box 1 and the second box 2 are equipped with cooling water inlet pipes 11 and cooling water outlet pipes on their sides. These pipes are connected to the cavities inside the double-layer structure of the box to circulate coolant and effectively reduce the temperature of the box and exhaust gas.

[0042] An air inlet flange is provided at the air inlet, connecting to housing 1. The air inlet flange has a first threaded hole for connecting exhaust pipe 3. An air outlet flange is provided at the air outlet, connecting to housing 2. The air outlet flange has a second threaded hole for connecting exhaust pipe 4. Both exhaust pipe 3 and exhaust pipe 4 are double-layered structures, with coolant inlet pipe 12 and coolant outlet pipe on the outer layer, matching the cooling system of the housing and further enhancing the cooling effect.

[0043] The exhaust gas enters the housing 1 through the exhaust pipe 3 and then through the intake flange. Upon entering the housing 1, the exhaust gas first comes into contact with the upper filter element 9, which is installed inside the upper bracket 5, located at the upper end of the housing 1. Several upper filter channels on the upper filter element 9 guide the exhaust gas through the filter element for preliminary CO dissolution and filtration.

[0044] The exhaust gas, after initial filtration, is then guided to the central partition 8, which separates housing 1 and housing 2, ensuring that the exhaust gas can fully contact the first filter element and be guided to housing 2. The exhaust gas enters housing 2 through the gap between the lower end of the central partition 8 and the bottom bracket 7, where the bottom bracket 7 is equipped with a lower filter element 10. Several lower filter channels on the lower filter element 10 further ablate and filter the CO in the exhaust gas. It is then discharged through the outlet flange. The exhaust pipe 4 is responsible for discharging the treated exhaust gas into a water tank (not shown in this embodiment).
