Description

Technical Field

[0001] The present application relates to the field of coal mine machinery and environmental protection technology, and in particular to a smoke and dust treatment device for a monorail crane heat exchanger. Background Art

[0002] As the coal industry modernizes, monorail crane transportation has become a vital component of mine transportation due to its efficient transport capacity, flexible material handling, and rapid track installation. However, during routine maintenance of monorail cranes, particularly cleaning heat exchangers, operational practices conflict with environmental and personnel health requirements.

[0003] Currently, the most common method for cleaning heat exchangers for monorail cranes is to use compressed air to directly blow away dust and impurities inside the heat exchanger. This method is simple and easy to use, and can quickly remove dirt adhering to the heat exchanger, ensuring the normal operation of the equipment.

[0004] While direct use of compressed air to clean heat exchangers can achieve rapid cleaning results, this process results in large amounts of smoke, dust, and harmful particulate matter being blown directly into the air within the mine tunnels, polluting the downwind air environment, reducing air quality, and posing a potential threat to miners' health. This pollution is particularly prone to accumulation in poorly ventilated mine tunnels, and in severe cases, can even endanger workers' lives, failing to meet the safety and environmental requirements of modern coal mine monorail crane transportation systems.

[0007] A negative pressure integrator and a spray atomization device are arranged in the housing along the direction from the air inlet to the air outlet;

[0008] It also includes an annular air duct; the annular air duct is arranged at the air outlet and is fixedly connected to the shell.

[0009] In a feasible implementation, the shell is a cylindrical structure, and the centers of the negative pressure integrator and the spray atomization device pass through the axis of the cylindrical structure.

[0011] In a feasible implementation, one side of the spray atomization device passes through the housing and is connected to a second pipe.

In a feasible implementation, the annular air duct is clamped to the air outlet of the housing using a clamp.

[0013] In a feasible implementation, the diameter of the annular air cylinder is 600 mm.

[0014] The embodiment of the present application provides a smoke treatment device for a monorail heat exchanger, in which a negative pressure integrator is arranged at the air inlet of the device, which can generate a strong negative pressure effect, effectively attract and concentrate the smoke generated from the outside, and ensure that the smoke is quickly captured in the early stage of discharge, thereby avoiding the diffusion of the smoke and secondary pollution. Subsequently, the water is finely atomized and fully mixed with the smoke through a spray atomization device, which not only achieves the wetting of the smoke, but also promotes the sedimentation of the smoke particles, greatly improving the purification efficiency of the smoke. The design of the annular wind tube being fixedly connected to the shell enhances the structural stability and dust removal effect of the entire device, and reduces the risk of damage caused by vibration or external force. The purification of the smoke is achieved by physical methods (negative pressure suction and spray atomization) without the use of chemical agents, and therefore has the characteristics of being environmentally friendly and pollution-free.

[0020] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0021] Monorail crane transportation is widely used in my country's coal industry due to its high transport efficiency, flexible material handling methods, and fast track installation. However, the current monorail crane system uses compressed air to clean heat exchangers, which can cause smoke, dust, and harmful particulate matter in the heat exchanger to be blown directly into the airflow, polluting the downwind air and reducing air quality. In severe cases, this can endanger the safety of workers and does not meet the requirements of monorail crane system construction.

[0022] The specific structure of a monorail heat exchanger smoke treatment device provided in this application is described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1 and Figure 2 As shown, an embodiment of the present application provides a smoke treatment device for a monorail heat exchanger, comprising: a shell 1, wherein an air inlet and an air outlet are respectively provided on both sides of the shell 1, to ensure that the dust blown out of the heat exchanger enters from the air inlet and is discharged from the air outlet after being processed, thereby forming a complete air flow channel and improving the efficiency of smoke treatment.

[0024] A negative pressure integrator 2 and a spray atomization device 3 are arranged in the shell 1 along the direction from the air inlet to the air outlet. The negative pressure integrator 2 generates negative pressure at the air inlet, effectively attracting external smoke and dust into the device, ensuring efficient collection of smoke and dust; the spray atomization device 3 atomizes water and mixes it with the incoming smoke and dust to achieve wetting and sedimentation of the smoke and dust, thereby improving the purification effect of the smoke and dust.

[0025] It also includes an annular wind tube 4; the annular wind tube 4 is arranged at the air outlet and is fixedly connected to the shell 1. The annular wind tube 4 helps to evenly distribute the airflow, reduce the turbulence of the airflow at the air outlet, improve the efficiency of exhausting the gas, and enhance the structural stability of the device.

[0026] The embodiment of the present application provides a smoke treatment device for a monorail heat exchanger. By arranging an air inlet and an air outlet on both sides of the shell 1, it ensures that the dust blown out of the heat exchanger can smoothly enter from the air inlet and be discharged from the air outlet after being processed, forming a complete air flow channel, thereby improving the fluidity and efficiency of the smoke treatment process. The negative pressure integrator 2 is installed at the air inlet position, which can generate negative pressure there, thereby effectively attracting external smoke and dust into the interior of the device, ensuring efficient collection of smoke and dust. The spray atomization device 3 is located after the negative pressure integrator and can atomize water and mix it with the incoming smoke and dust. This process not only makes the smoke and dust moist, but also is more conducive to the sedimentation of smoke and dust particles, thereby significantly improving the smoke and dust treatment effect. The annular air duct 4 is installed at the air outlet and is fixedly connected to the shell 1. It can not only help to evenly distribute the airflow and reduce the turbulence of the airflow at the air outlet, thereby improving the fluidity of the exhaust gas, but also enhance the overall structural stability of the device, ensuring long-term stable operation.

[0027] Reference Figure 1 and Figure 2 As shown, in some embodiments, the shell 1 is a cylindrical structure, and the centers of the negative pressure integrator 2 and the spray atomization device 3 pass through the axis of the cylindrical structure. The cylindrical shell and the symmetrical distribution design ensure uniform distribution of the airflow, reduce the resistance of the airflow in the shell, and improve the processing efficiency.

[0028] The cylindrical shell structure, combined with the central arrangement of the negative pressure integrator and the spray atomizer, ensures that the airflow is evenly distributed along the axis of the cylinder after entering the device. This design reduces airflow deviation and eddy currents within the shell, allowing the smoke and dust to more evenly contact the spray atomizer droplets, thereby improving the wetting and settling efficiency of the smoke and dust. The symmetrical distribution design is not only aesthetically pleasing but, more importantly, reduces the resistance of the airflow within the shell. The airflow flows smoothly within the cylinder, reducing energy loss due to resistance, allowing more energy to be used for smoke and dust collection and treatment, thereby improving the treatment efficiency of the entire device. The cylindrical shell structure itself has good stability and load-bearing capacity, and the central arrangement of the negative pressure integrator and the spray atomizer further enhances the structural symmetry, making the device more stable and reliable during operation. This design reduces the risk of structural deformation or damage due to vibration or external forces, thereby extending the service life of the device.

[0029] Reference Figure 1 and Figure 2 As shown, in some embodiments, one side of the negative pressure integrator 2 passes through the shell 1 and is connected to a first pipe 21, and the first pipe 21 is connected to an external high-pressure air duct to ensure smooth introduction of airflow.

[0030] The first pipe 21 allows high-pressure air to pass smoothly through the interface into the interior of the device. This direct connection method reduces the resistance and turbulence of the airflow during the introduction process, ensuring that pollutants such as smoke and dust can be efficiently sucked into the device for subsequent treatment. The presence of the first pipe 21 makes the smoke treatment device more flexible in installation and use. Appropriate pipes and connection methods can be selected according to actual needs, and the device can be flexibly arranged near the source of smoke and dust that needs to be treated, thereby maximizing its role. After the device has been running for a period of time, the first pipe 21 and the external pipes connected to it may affect the smooth introduction of the airflow due to dust accumulation or blockage. At this time, the user can restore its normal function by disassembling or cleaning the first pipe 21 and the pipes connected to it, thereby ensuring the long-term stable operation of the device.

[0031] Reference Figure 1 and Figure 2 As shown, in some embodiments, one side of the spray atomization device 3 passes through the shell 1 and is connected to a second pipe 31. The second pipe 31 is convenient for connecting to a high-pressure water source to ensure the smooth progress of the spray atomization. The first pipe 21 and the second pipe 31 are both detachable, easy to connect, and convenient for maintenance and replacement, thereby improving the ease of use of the device.

[0032] The presence of the second pipe 31 enables the spray atomization device 3 to be easily connected to an external high-pressure water source, thereby ensuring the smooth operation of the spray atomization. The high-pressure water source is stably supplied to the spray atomization device 3 through the second pipe 31, and after atomization treatment, a fine water mist is formed, which is fully mixed with the smoke and dust entering the device to achieve the wetting and sedimentation of the smoke and dust. Both the first pipe 21 and the second pipe 31 are detachable. After the device has been running for a period of time, the spray atomization device 3 or the external pipe may need to be maintained and replaced due to wear, blockage, etc. At this time, you only need to simply disassemble the quick connector to remove the parts that need maintenance or replacement, and then connect the new parts through the quick connector. The whole process is quick and efficient.

[0033] Reference Figure 1 and Figure 2 As shown, in some embodiments, the spray atomization device 3 is an annular structure, and a plurality of atomizing nozzles are evenly distributed on the annular structure. The multiple atomizing nozzles can spray water mist more evenly, increase the contact area with the smoke and dust, and improve the wetting and sedimentation effect of the smoke and dust.

[0034] By evenly distributing multiple atomizing nozzles on the annular structure, a continuous or nearly continuous annular water curtain can be formed. The annular water curtain can significantly increase the contact area between the water mist and the smoke, which helps to more effectively capture and wet the smoke particles and promote their sedimentation. Compared with single-point injection, the annular structure can ensure that the water mist is more evenly distributed throughout the space, avoiding local over-wetting or over-drying, and improving the overall processing efficiency. The arrangement of multiple atomizing nozzles enables the water mist to more comprehensively cover the airflow and smoke entering the device. The contact area between the water mist and the smoke is significantly increased, which is conducive to the wetting and sedimentation of the smoke particles. The smoke particles after being wetted are more likely to settle under the action of gravity due to the increase in weight, thereby improving the purification effect of the smoke. By designing the spray atomizing device 3 as an annular structure and evenly distributing multiple atomizing nozzles, it can be ensured that the water mist is sprayed more evenly inside the device.

[0035] Although the spray atomization device 3 adopts a multiple nozzle design, the spraying of the water mist is more uniform and efficient, which can actually reduce the consumption of water resources and energy. At the same time, due to the improvement of purification efficiency, the operating time of the device can also be shortened accordingly, further reducing energy consumption.

[0036] Reference Figure 1 and Figure 2 As shown, in some embodiments, the negative pressure integrator 2 includes several integrated units along the circumference of the shell 1, and the negative pressure integrator 2 is connected to the inner wall of the shell 1 through fixing claws. The design of the fixing claws ensures the stable installation of the negative pressure integrator 2, prevents loosening due to vibration, and improves the reliability and safety of the device; a filter is provided inside the negative pressure integrator 2, which can preliminarily filter the incoming smoke and dust, reduce large particles entering the subsequent processing links, and extend the service life of the spray atomization device 3.

[0037] The negative pressure integrator 2 is tightly connected to the inner wall of the shell 1 through fixing claws, ensuring that the negative pressure integrator 2 remains stable when running at high speed or subjected to external impact. Each circumferential integrated unit of the negative pressure integrator 2 is a relatively independent unit body and can be maintained and replaced separately. When an integrated unit fails or needs to be cleaned, it can be quickly located and processed without disassembling or shutting down the entire negative pressure integrator 2. The fixing claws effectively prevent the negative pressure integrator 2 from loosening or falling off due to vibration through their strong fixing force and stability, thereby improving the reliability and safety of the entire device. The filter screen installed inside the negative pressure integrator 2 can initially filter the smoke and dust entering the device and effectively intercept large particles before subsequent processing links. This design not only reduces the impact and wear of large particles on the spray atomization device, extending its service life, but also improves the efficiency and effectiveness of the entire smoke and dust treatment process. The preliminary filtration of the filter screen makes the smoke and dust entering the spray atomization device 3 more delicate and uniform, which is conducive to the full mixing and sedimentation of the water mist.

[0038] Reference Figure 1 and Figure 2 As shown, in some embodiments, the annular air duct 4 is clamped to the air outlet of the shell 1 by a clamp. The design of the clamp makes the connection between the annular air duct 4 and the shell 1 more convenient and firm, and is easy to install and disassemble, while ensuring the uniform distribution of the airflow at the air outlet, reducing the turbulence of the airflow, and improving the quality of the exhaust gas.

[0039] The clamp design ensures that the connection between the annular duct 4 and the shell 1 is firm and reliable. During the operation of the device, even if it is impacted or vibrated by the air flow, the clamp can maintain its connection stability and prevent the annular duct 4 from loosening or falling off. When the air flow passes through the annular duct 4, its flow rate and flow direction are further adjusted and optimized, reducing the turbulence and vortex phenomena of the air flow. By reducing the turbulence and vortex phenomena of the air flow, the design of the annular duct 4 also helps to improve the fluidity and efficiency of the smoke treatment process. During the smoke treatment process, the gas treated by the spray atomization device may still contain a certain amount of tiny particles. The uniform air flow distribution of the annular duct 4 helps these tiny particles to be better discharged from the outside of the device, thereby improving the purification treatment effect of the smoke.

[0040] Reference Figure 1 and Figure 2 As shown, in some embodiments, the diameter of the annular air duct 4 is 600 mm. The appropriate diameter size ensures the uniform distribution of the airflow at the air outlet, avoids excessive local pressure caused by concentrated airflow, and improves the stability and treatment effect of the airflow.

[0041] The diameter of 600mm ensures that the internal space of the annular duct 4 is sufficient, allowing the airflow to gradually diffuse and reach a balanced state during the flow process. It avoids excessive local pressure caused by the concentration of airflow at the air outlet, ensuring the uniform distribution of airflow. Evenly distributed airflow helps to reduce turbulence and vortex phenomena, and improve the stability and discharge effect of airflow. The appropriate diameter size also helps to reduce the energy consumption and noise level of the device. When the airflow flows smoothly in the duct, the energy loss and noise pollution caused by poor airflow or turbulence are reduced. This not only improves the operating efficiency of the device, but also improves the working environment. The diameter of 600mm also provides strong support for the structural stability of the annular duct 4. The larger diameter makes the duct more stable when subjected to the impact of airflow, reducing the risk of performance degradation or damage due to vibration or deformation.

[0042] According to the above technical features, the working principle of the smoke treatment device for a monorail heat exchanger provided by this application in actual application scenarios is as follows:

[0043] First, external dust-laden airflow is introduced into the device through the air inlet provided on the housing 1. The negative pressure integrator 2 located at the air inlet generates negative pressure, effectively drawing the external dust-laden airflow into the device and ensuring efficient collection of smoke and dust. A filter is provided within the negative pressure integrator 2 to initially filter out larger particles of impurities, reducing damage to subsequent processing components. The spray atomizer 3 then begins operation. The spray atomizer 3 is connected to an external high-pressure water source via a second pipe 31, atomizing the water into fine droplets that mix with the smoke and dust particles in the airflow. This process moistens the smoke and dust particles, increasing their weight and making them easier to settle. The design of multiple atomizing nozzles ensures uniform distribution of the water mist, increasing the contact area between the smoke and dust particles and the water mist, thereby improving purification efficiency. The treated airflow continues to move along the interior of the housing 1, ultimately reaching the air outlet. During this process, the annular air duct 4 installed at the air outlet is connected to the housing 1 via a clamp, enhancing the structural stability of the device, evenly distributing the airflow, reducing turbulence at the air outlet, and improving the fluidity and efficiency of the smoke and dust treatment process. The reasonable diameter design of the annular air duct 4 (e.g., 600mm) ensures uniform distribution of airflow at the outlet, avoids localized excessive pressure, and further improves airflow stability and treatment efficiency. To ensure long-term stable operation of the device, both the first pipe 21 and the second pipe 31 are designed as quick connectors for easy connection and removal, making maintenance and replacement more convenient for the user.
