Description

Technical Field

[0001] This invention relates to the field of exhaust gas treatment box technology, and particularly to an explosion-proof diesel engine exhaust gas treatment box. Background Technology

[0002] Explosion-proof diesel engines are widely used in auxiliary transportation equipment in coal mines, such as trackless rubber-tired vehicles and support transport vehicles. Coal mines contain flammable and explosive media such as methane and coal dust, which impose strict explosion-proof requirements on the exhaust components of diesel engines. The explosion-proof diesel engine exhaust gas treatment box is a special exhaust treatment device, mainly divided into two types: wet water bath structure and dry catalytic structure. It performs gas-liquid separation treatment on the exhaust gas flow to adapt to the overall assembly layout and exhaust flow path of the underground equipment.

[0003] A comprehensive exhaust gas treatment device for explosion-proof diesel engines, disclosed in CN116658276A, includes a housing, an exhaust gas purification unit cover, a purification carrier, a water-gas separator, a variable speed motor, a muffler, a backflow preventer, an electronically controlled shut-off valve, an analog level gauge, an exhaust temperature sensor, an exhaust back pressure sensor, an exhaust cap, an exhaust flame arrester, an electronically controlled treatment box, a water-gas separator inspection cover, a front air hood, a backflow preventer inspection cover, a rear air hood, an exhaust port, and a muffler inspection cover. Through the reasonable arrangement of these components, a comprehensive exhaust gas treatment device for explosion-proof diesel engines is formed.

[0004] There are still some problems with the current methods for treating exhaust gases.

[0005] In existing explosion-proof diesel engine exhaust gas treatment operations, most adopt a wet water bath structure to cool the exhaust gas. The cooled exhaust gas then flows through a three-way catalytic converter assembly, where harmful impurities in the exhaust gas are adsorbed and converted by the catalytic carrier to achieve exhaust gas purification. Under long-term continuous operation, impurities such as carbon soot particles and sludge carried in the exhaust gas will continue to accumulate inside the pores of the three-way catalytic converter carrier. The gradual accumulation of deposits can easily cause blockage of the catalytic carrier. After the carrier flow channel is blocked, it will not only change the flow state of the exhaust gas, but also interfere with the full contact between the catalytic components and the exhaust gas, thereby weakening the catalytic conversion capacity of the three-way catalytic converter assembly and causing a decline in the overall exhaust gas treatment performance. Summary of the Invention

[0006] The purpose of this invention is to provide an explosion-proof diesel engine exhaust gas treatment box, which cools the exhaust gas through a cooling component, while also mixing some impurities in the exhaust gas with cooling water. The treated exhaust gas enters the gas collection box through a flame arrestor grille.

The fire-resistant grille is located in the water bath. A flow guide and a cylindrical cover are installed inside the gas collection box, and the flow guide and the cylindrical cover are connected and communicate with each other. Several sets of air vents are opened on the surface of the cylindrical cover.

[0012] Preferably, a horizontal plate is fixedly installed on the inner wall of the shroud, and a shaft is provided in the axial direction inside the shroud. One end of the shaft is rotatably connected to the horizontal plate, and the other end of the shaft extends to the outside of the gas collection box and is fixedly connected to the output end of the drive motor.

[0017] In summary, the present invention has the following beneficial effects: 1. This invention features a water bath cooling structure. A water pump continuously draws cooling water from inside the water tank and sprays it onto the exhaust gas through a ring pipe and spray nozzles for cooling. This allows for rapid and uniform cooling of the high-temperature exhaust gas. Simultaneously, it dissolves most of the particulate impurities and oil sludge impurities in the exhaust gas into the cooling water, achieving preliminary purification of the exhaust gas. This effectively reduces the temperature and impurity content of the exhaust gas, avoids the safety hazards caused by direct emission of high-temperature exhaust gas, and meets the requirements for explosion-proof cooling in underground wells.

[0018] 2. A dynamically rotating adsorption structure is installed in the separation chamber. The fan driven by the drive motor actively draws in the exhaust gas, allowing the exhaust gas to enter the shroud stably. The rotating adsorption plate performs secondary adsorption and filtration on the fine impurities remaining in the exhaust gas. The dynamic rotation adsorption method can effectively expand the contact range between the exhaust gas and the adsorption plate, avoid local accumulation of impurities, significantly improve the filtration and purification effect of exhaust gas impurities, and reduce the total amount of impurities entering the subsequent three-way catalytic converter.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] It should be noted that the position sensors, solenoid valves, electrical control systems, PLC control logic, etc., not described in detail in the following embodiments are all conventional technical means in this field, and those skilled in the art can make conventional selections and parameter configurations according to actual working conditions.

[0024] Example: Reference Figures 1 to 10The explosion-proof diesel engine exhaust gas treatment box shown includes a box body 100, an air inlet pipe 101 connected to the air inlet end of the box body 100, an air outlet pipe 102 connected to the air outlet end of the box body 100, a waste liquid pipe 103 connected to the rear bottom of the box body 100, and the interior of the box body 100 is divided by a partition 104 to form a separation chamber 105 and a water bath 106; a cooling component 200 is installed inside the water bath 106 to cool the exhaust gas entering the box body 100; and a separation component 300 is installed inside the separation chamber 105 to adsorb impurities in the treated exhaust gas.

[0025] It should be noted here that, according to the appendix Figure 6 As shown, the exhaust gas enters the cooling component 200 through the intake pipe 101. The cooling component 200 cools the exhaust gas, and some impurities in the exhaust gas mix with the cooling water. The exhaust gas then rises and enters the separation component 300, where the separation component 300 adsorbs the impurities in the exhaust gas. Finally, the exhaust gas is discharged sequentially through the mixing box 401, the first pipe 402, the three-way catalytic converter 403, the second pipe 404, and the exhaust pipe 102.

[0026] In one embodiment of this invention, the cooling component 200 includes a cylinder 201, circular holes 202, a support 203, an annular tube 204, and a spray head 205. The cylinder 201 is disposed inside the water bath 106, and its top end is connected to and communicates with the air inlet pipe 101 at the air inlet end. Circular holes 202 are spaced apart on the surface of the cylinder 201. The support 203 is fixed to the surface of the cylinder 201. Several sets of annular tubes 204 are provided, and the annular tubes 204 are mounted around the support 203 and located around the periphery of the cylinder 201. The annular pipe 204 is equipped with a downward spray head 205. The annular pipe 204 is connected to the through pipe 207 on the outside of the box 100 through the branch pipe 206. The bottom end of the through pipe 207 is connected to the water pump 208. The water pump 208 is fixedly installed on one side of the bottom of the box 100. The water pump 208 is connected to the water tank 210 through the connecting pipe 209. The water tank 210 is fixedly installed on one side of the bottom of the box 100. The water bath 106 is provided with a base plate 211 at the bottom of the cooling component 200. Several sets of through holes 212 are opened on the base plate 211.

[0027] Specifically, the exhaust gas enters the cylinder 201 through the intake pipe 101 and is discharged into the water bath 106 through the round hole 202 on the cylinder 201. Then, the water pump 208 draws the cooling water inside the water tank 210 into the through pipe 207 through the connecting pipe 209. The cooling water inside the through pipe 207 then enters the annular pipe 204 through the branch pipe 206. The exhaust gas discharged through the round hole 202 is cooled by the spray head 205 on the annular pipe 204. At the same time, some impurities in the exhaust gas are mixed with the cooling water. The cooling water enters the bottom of the water bath 106 through the through hole 212 on the bottom plate 211 and is discharged from the bottom of the water bath 106 through the waste liquid pipe 103.

[0028] In one embodiment of this invention, the separation component 300 includes a gas collection box 301, a fire-resistant grille 302, a flow guide 303, a cylindrical cover 304, and vents 305. The gas collection box 301 is installed inside the separation chamber 105, and a fire-resistant grille 302 is provided at the air inlet end of the gas collection box 301. The fire-resistant grille 302 is located inside the water bath 106. The flow guide 303 and the cylindrical cover 304 are respectively installed inside the gas collection box 301. The flow guide 303 and the cylindrical cover 304 are connected and communicate with each other. Several sets of vents 305 are opened on the surface of the cylindrical cover 304. A horizontal plate 306 is fixedly installed on the inner wall of the cylindrical cover 304. A shaft 3 is provided in the axial direction inside the cylindrical cover 304. 07. One end of the shaft 307 is rotatably connected to the horizontal plate 306, and the other end of the shaft 307 extends to the outside of the air collection box 301 and is fixedly connected to the output end of the drive motor 308. The drive motor 308 is fixedly mounted on the air collection box 301. A fan 309 is fixedly mounted on one end of the shaft 307 near the horizontal plate 306. The fan 309 rotates by rotating the shaft 307 to draw the exhaust gas into the shroud 304. Several sets of rods 310 are provided on the surface of the shaft 307. At least four mounting brackets 311 are installed on the rods 310. Adsorption plates 312 are fixed on both sides of the mounting brackets 311. The adsorption plates 312 are set at an oblique angle. Blades 313 are spaced apart on the surface of the shaft 307.

[0029] Specifically, the exhaust gas rises and enters the gas collection box 301 through the flame arrestor grille 302. Then, the drive motor 308 operates to rotate the shaft 307. The rotation of the shaft 307 causes the fan 309 to draw the exhaust gas into the shroud 304. Then, the continuous rotation of the shaft 307 causes the mounting bracket 311 on the rod 310 to drive the adsorption plate 312 to rotate. The adsorption plate 312 adsorbs impurities in the exhaust gas. The rotation of the shaft 307 drives the blades 313 to push the surrounding exhaust gas away. Then, the exhaust gas is discharged into the gas collection box 301 through the air hole 305.

[0030] In one embodiment of this invention, the gas collection box 301 is connected to the mixing box 401 via the drainage pipe 400. The bottom end of the mixing box 401 is connected to the three-way catalytic converter 403 via the first pipe 402. The three-way catalytic converter 403 is fixedly installed on the bottom wall of the box body 100. The three-way catalytic converter 403 is connected to the gas outlet pipe 102 via the second pipe 404. An atomizing nozzle 405 is fixedly installed on the mixing box 401. The atomizing nozzle 405 is connected to the urea pump 408 via the first liquid pipe 406 and the second liquid pipe 407. The urea pump 408 is fixedly installed on one side of the mixing box 401. The urea pump 408 is connected to the storage tank 410 via the third liquid pipe 409. The storage tank 410 is located in the separation chamber 105.

[0031] Specifically, the exhaust gas treated inside the gas collection box 301 enters the mixing box 401 through the diversion pipe 400. Then, the urea pump 408 sprays urea from the storage tank 410 into the mixing box 401 through the atomizing nozzle 405 to mix with the exhaust gas. The exhaust gas then enters the three-way catalytic converter 403 through the first pipe 402. The three-way catalytic converter 403 can catalytically convert harmful gases in the exhaust gas. The treated exhaust gas enters the second pipe 404 and is then discharged through the exhaust pipe 102.

[0032] Working principle of this invention: When this explosion-proof diesel engine exhaust gas treatment box is working, the exhaust gas generated by the diesel engine is first introduced into the water bath 106 inside the box body 100 through the intake pipe 101. After the exhaust gas enters the cylinder 201, it is evenly discharged through the round holes 202 on the surface of the cylinder 201. At the same time, the water pump 208 draws cooling water from the water tank 210 through the connecting pipe 209 and delivers it to the through pipe 207. The cooling water is then distributed to each group of annular pipes 204 through the branch pipe 206, and finally sprayed downwards by the spray head 205 on the annular pipe 204 to spray and cool the high-temperature exhaust gas discharged from the round holes 202 in all directions. At the same time, the carbon soot, oil sludge and other impurities contained in the exhaust gas are fully mixed with the cooling water, realizing the initial interception of impurities and cooling of exhaust gas. The cooled water passes through the through holes 212 on the bottom plate 211 and collects at the bottom of the water bath 106, and can be discharged uniformly through the waste liquid pipe 103, completing the water circulation, impurity removal and cooling operation.

[0033] After initial cooling in a water bath, the exhaust gas flows upward, passes through the flame barrier 302, and enters the gas collection box 301 inside the separation chamber 105. At this time, the drive motor 308 starts, driving the shaft 307 to rotate continuously. The fan 309 at the end of the shaft 307 rotates synchronously, generating negative pressure to actively draw the exhaust gas into the shroud 304. During the rotation of the shaft 307, the rod body 310, the mounting bracket 311, and the obliquely arranged adsorption plate 312 rotate synchronously. The dynamically rotating adsorption plate 312 fully adsorbs and filters the fine impurities remaining in the exhaust gas. At the same time, the rotation of the shaft 307 drives the blades 313 to rotate, pushing the exhaust gas to all sides. After adsorption and purification, the exhaust gas is discharged back into the gas collection box 301 through the air holes 305 on the surface of the shroud 304.

[0034] The exhaust gas, after impurity separation in the gas collection box 301, is transported to the mixing box 401 via the guide pipe 400. The urea solution in the storage tank 410, under the action of the urea pump 408, is sequentially transported to the atomizing nozzle 405 through the third liquid pipe 409, the second liquid pipe 407, and the first liquid pipe 406. The atomizing nozzle 405 atomizes the urea solution and sprays it into the mixing box 401, where it is fully mixed with the exhaust gas. The mixed exhaust gas then enters the three-way catalytic converter 403 through the first pipe 402. The three-way catalytic converter 403 catalyzes and transforms the harmful gases in the exhaust gas, achieving deep purification. Finally, the purified exhaust gas is transported to the outlet pipe 102 through the second pipe 404 and discharged outwards, completing the entire exhaust gas cooling, impurity removal, and purification process.

[0035] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
