Description

Technical Field

[0001] This invention belongs to the field of exhaust gas treatment technology, specifically relating to a carbon monoxide disposal device for exhaust gas from mining fuel engines. Background Technology

[0002] Diesel engines employ lean-burn and compression ignition methods, resulting in more complete combustion and lower CO production. Therefore, most mining fuel engines are diesel-powered. Although diesel engines produce low levels of carbon monoxide in their exhaust, the unique characteristics of the mining environment necessitate purification treatment of the carbon monoxide in the exhaust of mining fuel engines.

[0003] Currently, carbon monoxide treatment in the exhaust gas of mining fuel engines typically involves catalytic oxidation of carbon monoxide with a carbon monoxide scavenger to produce carbon dioxide. Traditional treatment devices directly utilize the exhaust gas temperature to heat the scavenging tank, thereby activating the carbon monoxide scavenger within. However, considering that the scavenging tank is not fully heated and its temperature is low during the initial operation of the fuel engine, and that high temperatures occur inside the tank when the engine operates at high power, both excessively high and low temperatures are detrimental to the catalytic oxidation reaction of carbon monoxide. Consequently, current scavenging devices do not completely and thoroughly treat the carbon monoxide in the exhaust gas. Summary of the Invention

[0004] This invention provides a carbon monoxide disposal device for the exhaust gas of a mining fuel engine, which aims to improve the completeness of carbon monoxide disposal in the exhaust gas.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a carbon monoxide disposal device for the exhaust gas of a mining fuel engine is provided, comprising a disposal tank, one end of which is connected to the exhaust pipe of the fuel engine, and the other end is provided with an upwardly curved outlet pipe. Carbon monoxide disposal particles are disposed inside the disposal tank. The tank wall has a cooling water channel and an electric heating tube, and a temperature sensor with its sensing end extending into its inner cavity is provided on the disposal tank. The cooling water channel is used to connect to the coolant system of the fuel engine, and the inlet and / or outlet of the cooling water channel are provided with a switch valve. The switch valve and the electric heating tube are opened and closed based on the detection signal fed back to the overall controller by the temperature sensor.

[0006] In one possible implementation, the disposal tank includes: The tank body has an air inlet pipe at one end and an air outlet pipe at the other end. A baffle is installed inside the tank and divides the tank's internal cavity into an air inlet chamber and an air outlet chamber. The first partition sleeve is located between the air inlet pipe and the partition plate, and forms a first packing chamber with the inner peripheral wall of the tank. The peripheral wall of the first partition sleeve is provided with a first air hole array. The second partition sleeve is located between the gas outlet pipe and the partition plate, and forms a second packing chamber with the inner peripheral wall of the tank. The peripheral wall of the second partition sleeve is provided with a second vent array. The first and second packing chambers are connected by a third air hole array on the partition plate, and both the first and second packing chambers are filled with mixed packing material containing carbon monoxide dissipation particles.

[0007] In some embodiments, the mixed packing is a mixture of breathable and heat-conducting ball cages and carbon monoxide scavenging particles.

[0008] For example, the inner peripheral wall of the second partition is provided with a spiral guide vane suitable for guiding the airflow to the spiral flow of the air outlet pipe, and the inner wall of the second partition and the spiral guide vane are coated with a carbon monoxide dissipation coating.

[0009] For example, the tank body includes a heat-conducting layer, a heat-insulating layer, and an outer shell layer nested from the inside out; wherein, cooling water channels and electric heating pipes are provided between the heat-conducting layer and the heat-insulating layer.

[0010] In some embodiments, the outer peripheral wall of the heat-conducting layer is provided with a first spiral groove and a second spiral groove, a cooling water channel is formed between the heat-conducting layer and the heat insulation layer based on the first spiral groove, and the electric heating tube is embedded in the second spiral groove.

[0011] For example, the tank has two open ends and is detachably connected to an air inlet end cap and an air outlet end cap respectively. The air inlet end cap has an air inlet pipe in the center, and the air outlet end cap has an air outlet pipe in the center.

[0012] In some embodiments, a first positioning ring is provided on the side of the air inlet end cap facing the inside of the tank, and a second positioning ring is provided on the plate surface of the partition facing the air inlet end cap; the two ends of the first partition sleeve are respectively provided with positioning grooves suitable for the first positioning ring and the second positioning ring to be inserted.

[0013] In some embodiments, the side of the vent cap facing the interior of the tank has a first recessed stop, and the side of the partition facing the vent cap has a second recessed stop; the two ends of the second partition sleeve are respectively fitted into the first recessed stop and the second recessed stop.

[0014] The beneficial effects of the carbon monoxide disposal device for mining fuel engines provided by this invention are as follows: Compared with the prior art, in this invention, the exhaust gas of the mining fuel engine enters the disposal tank through the exhaust pipe when the fuel engine is working. During the process of the exhaust gas passing through the disposal tank, it comes into contact with carbon monoxide particles, causing the carbon monoxide in the exhaust gas to undergo catalytic oxidation to generate carbon dioxide and water, which are then discharged. The cooling water channel installed inside the disposal tank wall can cool the disposal tank, while the electric heating tube can heat the disposal tank. During the operation of the fuel engine, the temperature sensor can detect the temperature inside the disposal tank in real time and feed it back to the whole machine controller. Based on the detection value of the temperature sensor, the whole machine controller controls the electric heating tube to work when the temperature of the disposal tank is lower than the set range, and controls the switch valve to open to allow cooling water to flow into the cooling water channel when the temperature is higher than the set range. This ensures that the carbon monoxide particles inside the disposal tank are always kept within the temperature range suitable for the catalytic oxidation of carbon monoxide, thereby improving the completeness of carbon monoxide disposal in the exhaust gas.

[0017] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

It should be understood that the terms "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0019] Please refer to the following: Figures 1 to 5 The present invention will now describe the carbon monoxide disposal device for the exhaust gas of a mining fuel engine. The device includes a disposal tank 10, one end of which is connected to the exhaust pipe of the fuel engine, and the other end has an upwardly curved outlet pipe 101. Carbon monoxide disposal particles 301 are disposed inside the disposal tank 10. The tank wall of the disposal tank 10 has a cooling water channel 102 and an electric heating element 103. A temperature sensor 104 with its sensing end extending into the inner cavity is provided on the disposal tank 10. The cooling water channel 102 is used to connect to the coolant system of the fuel engine, and the inlet and / or outlet of the cooling water channel 102 are equipped with a switching valve 1021. Both the switching valve 1021 and the electric heating element 103 are opened and closed based on the detection signal fed back to the overall controller by the temperature sensor 104.

[0020] It should be understood that mining fuel engines are usually diesel engines, and their traditional exhaust gas treatment is a combination of a DOC unit (diesel oxidation catalyst), a CDPF unit (catalytic particulate filter), and an SCR unit (selective catalytic reduction system) installed on the exhaust pipe. The purpose of the mining fuel engine exhaust carbon monoxide disposal device provided in this embodiment is to replace the traditional DOC unit.

[0021] It should be noted that carbon monoxide digesters are typically granular non-precious metal catalysts with copper oxide and manganese dioxide as the main components. These catalysts possess high activity and can catalyze the reaction of carbon monoxide with oxygen in the air to produce carbon dioxide under suitable temperature conditions. In this embodiment, the carbon monoxide digester particles 301 can also be precious metal carbon monoxide catalysts, such as palladium series catalysts; no specific catalyst type is limited here. The carbon monoxide digester particles 301, filled in the digestion tank 10, utilize the gaps between the particles to provide a path for the exhaust gas. Furthermore, the exhaust gas makes full contact with the surface of the carbon monoxide digester particles 301 as it passes through the gaps, thereby ensuring complete digestion of carbon monoxide in the exhaust gas.

[0022] In this embodiment, the sensing end of the temperature sensor 104 extends into the interior of the carbon monoxide disposal tank 10 and directly contacts the carbon monoxide disposal particles 301. The temperature sensor 104 is electrically connected to the overall controller to provide a temperature detection signal. The electric heating element 103 is powered by the overall electrical system and controlled by the overall controller. The cooling water channel 102 is equipped with a switching valve 1021 at either the inlet or outlet, or both the inlet and outlet. The switching valve 1021 is an electrically controlled valve controlled by the overall controller.

[0023] During the initial operation of the fuel engine, the digester tank 10 is still at a low temperature. At this time, the temperature detected by the temperature sensor 104 is lower than the set range. Therefore, the engine controller energizes the electric heating element 103 to provide auxiliary heating to the digester tank 10. Once the temperature inside the digester tank 10 reaches the set range, the electric heating element 103 is de-energized. During continuous high-efficiency operation of the fuel engine, the high-temperature exhaust gas causes the temperature inside the digester tank 10 to rise continuously. When the temperature exceeds the set range, the engine controller controls the opening of the switching valve 1021 to allow the coolant in the cooling system to circulate in the cold water channel, thereby cooling the digester tank 10 until the waste is digested. The temperature of tank 10 returns to the set range, thereby ensuring that the temperature range inside the digestion tank 10 is always stable (the temperature set range is different for different types of digestion agents; for example, precious metal catalysts can be set to 150℃-200℃, while non-precious metal oxide catalysts need to be set to a higher 250℃-300℃). This avoids the degradation of digestion agent activity due to excessively low temperature (mainly for the initial start-up and low-load operation of the fuel engine), which would affect the complete catalytic oxidation of carbon monoxide, and the destruction and deactivation of digestion agent structure and the occurrence of side reactions due to excessively high temperature (mainly for the continuous high-load operation of the fuel engine).

[0024] Compared with the prior art, the carbon monoxide disposal device for mining fuel engine exhaust gas provided in this embodiment involves the following steps: When the fuel engine is working, the exhaust gas enters the disposal tank 10 through the exhaust pipe. During the process of the exhaust gas passing through the disposal tank 10, it comes into contact with the carbon monoxide disposal particles 301, causing the carbon monoxide in the exhaust gas to undergo catalytic oxidation to generate carbon dioxide for emission. The cooling water channel 102 provided in the tank wall of the disposal tank 10 can cool the disposal tank 10, and the electric heating tube 103 can heat the disposal tank 10. During the operation of the fuel engine, the temperature sensor 104 can detect the temperature inside the disposal tank 10 in real time and feed it back to the whole machine controller. Based on the detection value of the temperature sensor 104, the whole machine controller controls the electric heating tube 103 to work when the temperature of the disposal tank 10 is lower than the set range, and controls the switch valve 1021 to open when the temperature is higher than the set range, so that cooling water can be introduced into the cooling water channel 102. This ensures that the carbon monoxide disposal particles 301 inside the disposal tank 10 are always kept in the temperature range suitable for the catalytic oxidation of carbon monoxide, thereby improving the completeness of carbon monoxide disposal in the exhaust gas.

[0025] For a specific structural configuration of the aforementioned waste disposal tank 10, please refer to [link / reference]. Figure 2 and Figure 3 The disposal tank 10 includes a tank body 11, a partition 12, a first partition sleeve 13, and a second partition sleeve 14. One end of the tank body 11 is provided with an air inlet pipe 1101, and the other end is provided with an air outlet pipe 1102. The partition 12 is disposed inside the tank body 11 and divides the inner cavity of the tank body 11 into an air inlet chamber and an air outlet chamber. The first partition sleeve 13 is disposed between the air inlet pipe 1101 and the partition 12, and forms a first packing chamber 1103 between it and the inner peripheral wall of the tank body 11. The peripheral wall of the first partition sleeve 13 is provided with a first pore array 13. 1; The second partition 14 is located between the gas outlet pipe 1102 and the partition 12, and forms a second packing chamber 1104 between it and the inner peripheral wall of the tank body 11. The peripheral wall of the second partition 14 is provided with a second vent array 141; wherein, the first packing chamber 1103 and the second packing chamber 1104 are connected through a third vent array 121 opened on the partition 12. The first packing chamber 1103 and the second packing chamber 1104 are both filled with mixed packing 30 containing carbon monoxide dissipation particles 301.

[0026] The tank body 11 is divided into two packing chambers by a partition 12, a first partition 13, and a second partition 14. The exhaust gas enters the first partition 13 through the inlet pipe 1101, and then diffuses into the first packing chamber 1103 through the first pore array 131 on the periphery of the first partition 13. In the first packing chamber 1103, the exhaust gas makes initial contact with the carbon monoxide absorbing particles 301 to absorb the carbon monoxide. Then, it passes through the third pore array 121 on the partition 12 and enters the second packing chamber. In the second packing chamber, it makes secondary contact with the carbon monoxide absorbing particles 301 to absorb the residual carbon monoxide. Finally, it enters the second partition 14 through the second pore array 141 on the periphery of the second partition 14 and is discharged through the outlet pipe 1102. The complete absorption of carbon monoxide in the exhaust gas is ensured through the secondary absorption process.

[0027] Specifically, in some embodiments, see Figure 3 The mixed packing 30 is a mixture of a permeable and heat-conducting ball cage 302 and carbon monoxide absorbing particles 301. Considering that directly filling the first and second packing chambers 1103 and 1104 with the carbon monoxide absorbing particles 301 might affect airflow and thus the normal operating efficiency of the fuel engine, the permeable and heat-conducting ball cage 302 is mixed with the carbon monoxide absorbing particles 301 and then used as the mixed packing 30 to fill the first and second packing chambers 1103 and 1104. The permeable and heat-conducting ball cage 302 supports sufficient interparticle gaps between the carbon monoxide absorbing particles 301. This ensures the smooth flow of exhaust gas through the first and second packing chambers 1103 and 1104, and also increases the specific surface area of ​​the carbon monoxide absorbing particles 301 by reducing their particle size, thereby improving the sufficiency and uniformity of contact between the carbon monoxide absorbing particles 301 and the exhaust gas, and ultimately improving the completeness of carbon monoxide absorption.

[0028] Specifically, the breathable and heat-conducting ball cage 302 can be an integrated cage structure formed by radially intersecting and fixing several heat-conducting metal rings. It not only has good air permeability, but also conducts heat between the carbon monoxide absorbing particles 301 in contact with it, thereby improving the temperature uniformity of the carbon monoxide absorbing particles 301, and thus improving the stability and efficiency of the carbon monoxide catalytic oxidation process.

[0029] For some possible implementations, please refer to [link / reference]. Figure 2 The inner peripheral wall of the second partition 14 is provided with a spiral guide vane 142, which is suitable for guiding the airflow to spiral flow towards the air outlet pipe 1102.

[0030] The exhaust gas enters the second partition 14 through the second air hole array 141 in the radial direction of the second partition 14, and finally needs to enter the exhaust pipe 1102 along the axial direction of the second partition 14. The change in airflow direction may cause exhaust gas blockage and affect the smoothness of exhaust. Therefore, a spiral guide vane 142 is set to guide the exhaust gas to form a spiral flow exhaust path in the second partition 14, thereby improving the smoothness of exhaust.

[0031] Based on the aforementioned spiral guide vane 142, in this embodiment, a carbon monoxide absorption coating is applied to both the inner wall of the second partition 14 and the spiral guide vane 142. The spiral guide vane 142 not only improves the smoothness of exhaust gas discharge but also extends the path of the exhaust gas through the interior of the second partition 14, allowing the exhaust gas to fully contact the carbon monoxide absorption coating on the inner wall of the second partition 14 and the spiral guide vane 142. This further absorbs the carbon monoxide remaining in the exhaust gas, improving the completeness and thoroughness of carbon monoxide absorption treatment.

[0032] It should be noted that the above-mentioned carbon monoxide digestion coating can be made of carbon monoxide digestion agent, which has the same catalytic oxidation effect as carbon monoxide digestion particles 301.

[0033] Specifically, such as Figure 2 As shown, in this embodiment, the tank 11 includes a heat-conducting layer 111, a heat-insulating layer 112, and an outer shell layer 113 nested from the inside out; wherein, a cooling water channel 102 and an electric heating tube 103 are provided between the heat-conducting layer 111 and the heat-insulating layer 112.

[0034] The heat-conducting layer 111 can be made of heat-conducting metal materials such as copper or aluminum, the heat insulation layer 112 can be made of heat-insulating materials such as ceramics, and the outer shell layer 113 can be a conventional metal shell or a plastic shell.

[0035] The heat-conducting layer 111 and the electric heating tube 103 can quickly and evenly transfer heat to the carbon monoxide digestion particles 301. At the same time, the cooling water channel 102 on the outer periphery of the heat-conducting layer 111 can achieve efficient cooling of the carbon monoxide digestion particles 301, thereby improving the temperature control response speed of the carbon monoxide digestion particles 301, which is conducive to maintaining the temperature stability of the carbon monoxide digestion particles 301, thereby improving the catalytic oxidation efficiency of carbon monoxide, and thus ensuring the complete treatment of carbon monoxide in the exhaust gas.

[0036] Furthermore, such as Figure 5 As shown, the outer peripheral wall of the heat-conducting layer 111 is provided with a first spiral groove 1111 and a second spiral groove 1112. A cooling water channel 102 is formed between the heat-conducting layer 111 and the heat insulation layer 112 based on the first spiral groove 1111. The electric heating tube 103 is embedded in the second spiral groove 1112.

[0037] By processing the first spiral groove 1111 and the second spiral groove 1112 on the outer periphery of the heat-conducting layer 111, the first spiral groove 1111 and the second spiral groove 1112 can be sealed by the inner wall of the heat insulation layer 112 after the heat-conducting layer 111 is embedded in the heat insulation layer 112, thereby forming a spirally extending water-cooling channel and a space suitable for accommodating the electric heating tube 103, which can reduce the difficulty of processing and manufacturing.

[0038] It should be noted that you should refer to [link / reference]. Figure 2 and Figure 4 The tank body 11 is open at both ends and is detachably connected to an air inlet cap 114 and an air outlet cap 115 respectively. The air inlet cap 114 is provided with an air inlet pipe 1101 at its center, and the air outlet cap 115 is provided with an air outlet pipe 1102 at its center.

[0039] Both the inlet end cap 114 and the outlet end cap 115 can be detachably connected to the tank body 11 through several threaded connectors distributed circumferentially. This allows the inlet end cap 114 to be removed separately to open the first packing chamber 1103 and the outlet end cap 115 to be removed separately to open the second packing chamber 1104, thereby improving the convenience of assembly and the convenience of later maintenance and replacement of carbon monoxide particles 301.

[0040] To improve the connection stability and positional accuracy of the first spacer 13 within the tank body 11, such as Figure 4 As shown, the air inlet end cap 114 is provided with a first positioning ring 1141 on the side facing the inside of the tank body 11, and the partition plate 12 is provided with a second positioning ring 122 on the plate surface facing the air inlet end cap 114; the two ends of the first partition sleeve 13 are respectively provided with positioning grooves 132 suitable for the first positioning ring 1141 and the second positioning ring 122 to be embedded.

[0041] Please see Figure 4 The second spacer 14 is fixed in the tank body 11 as follows: a first recessed stop 1151 is provided on the side of the gas outlet cap 115 facing the inside of the tank body 11, and a second recessed stop 123 is provided on the side of the partition plate 12 facing the gas outlet cap 115; the two ends of the second spacer 14 are respectively fitted into the first recessed stop 1151 and the second recessed stop 123. The first recessed stop 1151 and the second recessed stop 123 respectively form positioning constraints on the two ends of the second spacer 14, thereby ensuring the installation stability of the second spacer 14.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
