Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and in particular to a highly efficient cooling waste gas treatment device for underground explosion-proof vehicles. Background Technology

[0002] In the underground coal mine environment, the high-temperature exhaust gas produced by explosion-proof diesel vehicles contains a large amount of carbon soot particles and harmful vapors, and the exhaust temperature is usually as high as 300-400℃. Direct emission of this gas can easily become an ignition source for gas or coal dust explosions. To comply with the "Coal Mine Safety Regulations" which stipulate that the exhaust temperature should not exceed 77℃ and to effectively separate particulate matter from the exhaust gas, a wet liquid scrubbing system is used. This system typically consists of a front-end double-layer water-cooled exhaust pipe assembly connected in series with a rear-end exhaust gas treatment box. The double-layer water-cooled exhaust pipe assembly, as the core pretreatment unit, adopts a stainless steel double-layer hollow seamless pipe structure. A circulating cooling water is filled in the annular interlayer between the outer and inner pipes. Before the exhaust gas enters the subsequent exhaust gas treatment device, the exhaust pipe needs to be drastically cooled. A corrugated pipe structure is installed in the middle section of the exhaust pipe to compensate for thermal stress, ensuring the safe operation of the entire gas-liquid treatment system.

[0003] However, in practical applications, the aforementioned devices using liquid as a cooling and separation medium have significant technical defects that limit purification and cooling efficiency: First, due to the narrow gap between the inner and outer pipe layers and the lack of an active turbulence mechanism, the cooling water close to the high-temperature inner pipe wall is prone to film boiling. The generated steam bubbles cannot be flushed away in time, resulting in steam resistance with extremely low thermal conductivity. This not only hinders the transfer of heat to the liquid, causing the exhaust temperature to fail to stabilize and drop to a safe level, but may also lead to rupture of the inner pipe due to local overheating. Second, although the corrugated pipe section in the existing device solves the flexibility requirement of the mechanical connection, its folds and grooves create dead zones for air and scale accumulation in terms of fluid dynamics. The easily accumulated air pockets block the contact between the coolant and the pipe wall, while the deposited scale and sludge further deteriorate the system's heat transfer performance, thus posing serious safety hazards.

[0004] Therefore, it is necessary to invent a highly efficient cooling exhaust gas treatment device for underground explosion-proof vehicles to solve the above problems. Summary of the Invention

[0019] Compared with the prior art, the present invention provides a highly efficient cooling exhaust gas treatment device for underground explosion-proof vehicles, which has the following beneficial effects:

[0020] 1. This high-efficiency cooling exhaust gas treatment device for underground explosion-proof vehicles uses a rotating rod to drive the high-speed rotation of the rod through a diverted high-pressure water flow. Combined with the serrated teeth on the surface of the turbulence blades, it can actively perform physical shearing and strong stirring of the fluid layer on the outer wall of the inner tube. This effectively breaks the film boiling gas resistance caused by high temperature, transforms laminar flow into violent turbulence, greatly improves the heat exchange efficiency between the cooling water and the inner tube, and prevents the inner tube from deforming or cracking due to excessive local thermal stress.

[0021] 2. This high-efficiency cooling underground explosion-proof vehicle exhaust gas treatment device, by setting up an annular plate and scavenging brushes, uses fluid power to drive the scavenging brushes to automatically sweep deep into the folds of the corrugated pipe. At this time, it can not only force the air pockets trapped in the dead corners of the corrugated pipe crests to eliminate heat insulation hazards, but also remove the deposited scale and silt online, solving the technical problem of easy scale accumulation and corrosion in the corrugated pipe, and significantly extending the service life of the device.

[0022] 3. This highly efficient cooling exhaust gas treatment device for underground explosion-proof vehicles achieves electrical-free, visual monitoring of its operating status by incorporating transparent tubes and colored floats. Operators can intuitively determine whether the internal rotating rod is operating normally and whether the water passage is unobstructed simply by observing the movement of the colored floats, avoiding risks caused by mechanical jamming. Simultaneously, the spiral connecting pipe wound around the surface of the outer tube effectively utilizes the residual energy of the return water to provide secondary auxiliary cooling to the outer tube, further reducing the surface temperature of the device and improving the safety of underground operations.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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. Therefore, they should not be construed as limitations on this invention.

[0035] Reference Figure 1 - Figure 9 A high-efficiency cooling exhaust gas treatment device for underground explosion-proof vehicles includes an outer pipe 1, which serves as the outer shell and is preferably made of high-temperature resistant and corrosion-resistant stainless steel. An engine body 7 is fixedly connected to the left side of the outer pipe 1 via high-strength bolts. An inner pipe 11 is coaxially arranged inside the outer pipe 1, forming a sealed annular cavity for coolant flow. The two ends of the outer pipe 1 and the inner pipe 11 are sealed and fixedly connected by standard flanges to ensure a tight connection. The outer pipe 1 is fixedly connected to the exhaust port of the engine body 7 via flanges, and the exhaust gas generated by the engine body 7 is directly introduced into the inner pipe 11. A corrugated pipe 12, made of stainless steel, is provided in the middle of both the outer pipe 1 and the inner pipe 11 to provide axial expansion and contraction compensation in high-temperature environments. A pressure loss sensor 13 is fixedly installed at the bottom of the middle section of the outer pipe 1 to monitor pressure changes within the interlayer. A resistance sensor 14 is fixedly installed on the surface of the bottom right side of the inner pipe 11 to monitor flow resistance. A water inlet pipe 15 is fixedly connected to the upper left side of the outer tube 1 as a cooling water inlet, and a water outlet pipe 16 is fixedly connected to the bottom right side of the outer tube 1 as a cooling water outlet, forming a diagonal flow path to improve the cooling water filling degree. A fireproof braided mesh 17 is fixedly installed on the surface of the middle part of the outer tube 1, and is fixed on both sides by two knots, which serves as protection and flame retardancy. It also includes: a spiral rod 24, which generates rotational torque by the impact of water flow on the spiral surface of the spiral rod 24. The spiral rod 24 is set between the outer tube 1 and the inner tube 11, and the surface of the spiral rod 24 is fixedly connected to the scavenging bristles 25; a hollow tube 31, which is vertically welded and fixedly installed on the top of the outer tube 1. A rotating rod 32 is rotatably connected inside the hollow tube 31. A turbine 33 is fixedly installed on the surface of the rotating rod 32. A baffle blade 34 is fixedly installed on the bottom surface of the rotating rod 32. The surface of the baffle blade 34 is provided with serrated teeth 35.

[0036] Specifically, when the engine block 7 starts, exhaust gas at temperatures as high as 300-400°C enters and flows into the inner pipe 11. Simultaneously, an external water pump forces cooling water in through the inlet pipe 15. The cooling water quickly fills the space between the outer pipe 1 and the inner pipe 11, thus facilitating heat exchange and cooling. During this process, the bellows 12 automatically expands and contracts, absorbing thermal stress caused by the asynchronous temperature difference between the inner and outer pipes 11, preventing weld tearing. The pressure sensor 13 and resistance sensor 14 are constantly monitoring; if a leak causes pressure loss or pipe blockage leads to abnormal resistance, they immediately send a signal to alert the operator.

[0037] Reference Figure 2 - Figure 5 A high-efficiency cooling exhaust gas treatment device for underground explosion-proof vehicles is disclosed. A fixing ring 2 is welded and fixed to the inner wall of the outer pipe 1, serving as support and guide. An arc-shaped groove 21 is formed on the left side of the fixing ring 2, and a connecting groove 22 is formed on the right side. The arc-shaped groove 21 and the connecting groove 22 are connected and extend through both sides of the fixing ring 2 to ensure smooth passage of the main cooling water. The scavenging brush bristles 25 are made of flexible, wear-resistant material, and are adapted to the deep troughs of the corrugated pipe 12 to ensure no dead-angle coverage. An annular plate 23 is fixedly connected to the right side of the spiral rod 24. A limiting hemisphere 26 is fixedly installed on the right end face of the annular plate 23. The limiting hemisphere 26 is circumferentially distributed and slidably connected inside the arc-shaped groove 21. The limiting hemisphere 26 and the arc-shaped groove 21 cooperate to form a sliding bearing structure, restricting the axial displacement of the annular plate 23 and allowing only circumferential rotation.

[0038] Specifically, when the main flow of cooling water flows to the right in the space between the outer pipe 1 and the inner pipe 11, the water flow impacts the surface of the spiral blades of the spiral rod 24. According to the principles of fluid dynamics, the axial flow of water is converted into torque that drives the spiral rod 24 to rotate, which in turn drives the annular plate 23 to rotate. The rotation of the annular plate 23 causes the scavenging bristles 25 on its surface to move in a circular motion inside the folds of the bellows 12. The scavenging bristles 25 continuously sweep across the corrugated grooves of the bellows 12, scraping away the mud and scale deposited there due to the slow water flow, and using the centrifugal force generated by the agitation, forcibly squeezing out the air pockets that easily accumulate on the top of the corrugated convex surface into the main flow area, where they are carried away by the water flow, thereby eliminating localized air accumulation in the insulation layer and scale corrosion points.

[0039] Reference Figure 3 , Figure 6 and Figure 7A high-efficiency cooling exhaust gas treatment device for underground explosion-proof vehicles is disclosed. A water inlet pipe 15 is connected by a bypass to a water guide pipe 3, which is connected to the top of a hollow pipe 31. The water guide pipe 3 is inclined downwards to form a tangential impact angle. The bottom end of a rotating rod 32 extends deep into the interior of the outer pipe 1 through the walls of the hollow pipe 31 and the outer pipe 1. A high-temperature and high-pressure resistant sealing ring is installed between the rotating rod 32 and the outer wall of the outer pipe 1 to prevent cooling water leakage. Three sets of serrated teeth 35 are evenly spaced in the vertical direction of the rotating rod 32, and the vertical turbines 33 are staggered. This staggered design increases the force-bearing area of ​​the water flow impact, ensuring the continuity of the rotational torque. Simultaneously, the serrated structure of the serrated teeth 35 enhances the shearing and destructive ability against the fluid.

[0040] Specifically, a portion of the high-pressure water entering from the inlet pipe 15 is diverted through the guide pipe 3, rushing at high speed into the hollow tube 31 and impacting the turbine 33. The turbine 33, under pressure, drives the rotor 32 to rotate at high speed. The rotor 32 drives the bottom turbulence-inducing blades 34 to rotate within a narrow interlayer gap. The serrated teeth 35 on the surface of the turbulence-inducing blades 34 exert strong physical shearing on the water layer close to the outer wall of the high-temperature inner tube 11. Once tiny film boiling bubbles are generated on the surface of the inner tube 11 due to the high temperature, the serrated teeth 35 instantly break them up and entrain them into the turbulence, preventing the bubbles from agglomerating and forming an air-resistance film. By generating turbulence, the convective heat transfer coefficient is greatly improved, ensuring that the inner tube 11 receives uniform and efficient cooling.

[0041] Reference Figure 7 - Figure 9A connecting pipe 4 is fixedly connected to the bottom right side of the hollow tube 31 to discharge the water flow driven by the turbine 33. A transparent tube 41 is fixedly connected to the right side of the connecting pipe 4. The transparent tube 41 is made of high-strength transparent material for easy external observation. A limiting block 42 is fixedly installed on the right side inside the transparent tube 41. The inner diameter of the limiting block 42 gradually decreases from left to right to form a nozzle shape. The surface of the limiting block 42 has through holes to allow water to pass through. A colored float 43 is installed inside the transparent tube 41. The colored float 43 is a colored indicator ball with a density less than water. A second connecting pipe 5 is fixedly connected to the right side of the transparent tube 41. A corrugated inner wall 51 is fixedly installed on the inner wall of the second connecting pipe 5. The corrugated inner wall 51 is non-smooth. A fixing sleeve 52 is fixedly installed on the surface of the connecting pipe 2 5. A connector 53 is fixedly installed at the bottom of the fixing sleeve 52. The combinations of fixing sleeve 52 and connector 53 are evenly distributed on the surface of the connecting pipe 2 5. The connector 53 is fixedly connected to the fireproof braided mesh 17 to transmit the vibration effect. A spiral connecting pipe 6 is fixedly connected to the right side of the connecting pipe 2 5. A water guide pipe 2 61 is fixedly connected to the side of the spiral connecting pipe 6 away from the connecting pipe 2 5. The end of the water guide pipe 2 61 away from the spiral connecting pipe 6 is fixedly connected to the surface of the water outlet pipe 16. The spiral connecting pipe 6 is spiral-shaped and tightly wound around the outer surface of the outer pipe 1 to form an external water-cooling jacket. The interior of the water guide pipe 2 61 and the water outlet pipe 16 are connected to guide the return water back to the main line.

[0042] Specifically, the water flowing after the turbine 33 has performed its work enters the transparent tube 41. The flowing water impacts the colored float 43, causing it to tumble and bounce within the tube. Operators can determine whether the internal rotating rod 32 is rotating to degas simply by observing the movement of the colored float 43, without the need for electronic instruments, achieving visual monitoring without power. The water then flows through the connecting pipe 5 with its corrugated inner wall 51. The pulsating pressure of the water causes the connecting pipe 5 to vibrate slightly. This vibration is transmitted to the fireproof braided mesh 17 and the outer tube 1 via the connector 53, helping to prevent the sedimentation of suspended impurities inside the device. Finally, this lower-temperature diversion flows into the spiral connecting pipe 6, flowing close to the outer wall of the outer tube 1. This diversion absorbs the heat radiated outward from the outer tube 1, providing secondary auxiliary cooling to the device and thus reducing the surface temperature of the equipment.

[0043] In this invention, when the engine body 7 starts running, the generated high-temperature exhaust gas is directly discharged into the inner pipe 11 and flows to the right into the subsequent treatment stage. Simultaneously, the external circulating cooling water system pumps cooling water into the inlet pipe 15. The cooling water quickly fills the annular interlayer between the outer pipe 1 and the inner pipe 11. The low-temperature cooling water exchanges heat with the high-temperature inner pipe 11 wall, carrying away the heat from the exhaust gas and reducing its temperature to below 77°C. The cooled water eventually flows out through the outlet pipe 16 and returns to the external radiator for circulation. During this process, the corrugated pipe 12 installed in the middle section of the outer pipe 1 and the inner pipe 11 effectively compensates for the axial thermal expansion and contraction stress caused by the temperature difference.

[0044] The high-pressure water entering from the inlet pipe 15 is partially diverted into the inclined guide pipe 3, where it rushes into the hollow tube 31 at high speed. This diverted water then impacts the turbine 33 on the surface of the rotating rod 32, driving the rod 32 to rotate. The rotation of the rod 32 causes the turbulence-inducing blades 34 at its bottom to rotate at high speed within the gap between the outer tube 1 and the inner tube 11. The serrated teeth 35 on the surface of the turbulence-inducing blades 34 forcefully shear and stir the water layer close to the outer wall of the inner tube 11, instantly shattering the newly generated tiny steam bubbles and preventing them from accumulating and forming a gas film. Therefore, the turbulence mechanism greatly improves the heat transfer coefficient, preventing localized overheating of the inner tube 11.

[0045] Simultaneously, as the main water flow enters the outer pipe 1 through the inlet pipe 15 and flows to the right within the interlayer, the main water flow impacts the annular plate 23 positioned between the outer pipe 1 and the inner pipe 11. Utilizing fluid dynamics, the water flow drives the spirally arranged screw rod 24 to rotate, causing the annular plate 23, fixedly connected to the right side of the screw rod 24, to also rotate. The limiting hemisphere 26 on the end face of the annular plate 23 slides circumferentially within the arcuate groove 21 on the side of the fixed ring 2, ensuring smooth movement of the screw rod 24 and the annular plate 23. During the rotation of the screw rod 24, the scavenging brush bristles 25 fixed to its surface also rotate. The scavenging brush bristles 25 extend into the deep folds and troughs of the bellows 12 to perform physical scavenging. This process utilizes centrifugal force and mechanical agitation to force the air pockets trapped in the dead corners of the convex surface of the bellows 12 to be discharged into the mainstream area. On the other hand, the scavenging brush bristles 25 continuously rub the inner wall of the bellows 12, which can remove the deposited scale and silt online and prevent blockage. This pushes the air pockets and scale and silt into the mainstream, and then transports the air pockets and scale and silt to the external radiator tank through the mainstream.

[0046] After the water has done its work on the turbine 33, it flows out from the bottom of the hollow tube 31 and enters the interior of the connecting tube 4. When the water flows through the transparent tube 41, the kinetic energy of the water impacts the colored float 43. At this time, the operator can observe through the transparent tube 41. If the colored float 43 is rolling and jumping up and down, it proves that the water passage is unobstructed and the turbine 33 is driving the rotating rod 32 to rotate and remove bubbles. If the colored float 43 is stationary, it indicates that the turbine 33 may be stuck or the water passage is interrupted. This allows for observation of the internal condition of the hollow tube 31 and a direct judgment of the working status of the rotating rod 32 inside the hollow tube 31. Subsequently, the water flows into the interior of the connecting tube 5. Affected by the corrugated structure of the corrugated inner wall 51, the water flow causes the connecting tube 5 to vibrate slightly, thus preventing the deposition of impurities inside the connecting tube 5. Furthermore, since the connecting pipe 2 5 is fixedly connected to the fireproof braided mesh 17 through the connector 53, during the slight vibration of the connecting pipe 2 5, the fireproof braided mesh 17 will also vibrate slightly through the connector 53, thereby causing the outer pipe 1 to vibrate slightly. At this time, it also prevents air bubbles from accumulating on the inner wall of the corrugated pipe 12 in the middle of the outer pipe 1 and forming an air film.

[0047] The rear end of the connecting pipe 2 5 is connected to a spiral connecting pipe 6 that is spirally wound on the surface of the outer pipe 1. The low-temperature water inside the connecting pipe 2 5 wraps around the outer wall of the outer pipe 1 again. Through the heat conduction between the wall of the spiral connecting pipe 6 and the outer wall of the outer pipe 1, the surface temperature of the device is further reduced. Finally, it flows out through the water guide pipe 2 61 into the outlet pipe 16 and then returns to the external heat dissipation water tank for circulation.

[0048] Throughout the operation, the pressure loss sensor 13 installed on the outer pipe 1 and the resistance sensor 14 at the end of the inner pipe 11 monitor the pressure and flow resistance of the outer pipe 1 and the inner pipe 11 in real time. If the inner pipe 11 or the bellows 12 ruptures, causing internal or external leakage, or if the circulation system pressure is abnormal, the pressure loss sensor 13 and the resistance sensor 14 will immediately send back a signal to trigger an alarm, thus achieving active safety protection.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
