Description

Technical Field

[0001] This utility model relates to the technical field of dust removal devices, specifically to a water-cooled integrated cyclone dust removal device. Background Technology

[0002] In modern industrial production, dust removal devices are crucial for ensuring a clean production environment and reducing air pollution. Cyclone dust collectors, as a common type of dust removal equipment, are widely used in industries such as cement, metallurgy, and chemicals.

[0003] Cyclone dust collectors work by separating dust particles from the air through high-speed rotating airflow. However, traditional cyclone dust collectors have some shortcomings in practical applications, especially in high-temperature and high-humidity environments, where dust removal efficiency will decrease significantly and the equipment is easily damaged by high temperatures.

[0004] Traditional cyclone dust collectors experience a significant decrease in dust removal efficiency under high-temperature conditions, primarily because the low density of high-temperature gases results in insufficient centrifugal force and poor dust separation. High-temperature gases also place higher demands on the materials used in the dust collector, and prolonged operation at high temperatures can easily lead to equipment deformation, aging, or even damage. Furthermore, traditional cyclone dust collectors typically require additional cooling equipment when handling high-temperature gases, increasing energy consumption and operating costs. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a water-cooled integrated cyclone dust collector.

[0006] The technical solution of this utility model is a water-cooled integrated cyclone dust removal device: including a housing, an air inlet pipe and an air outlet pipe disposed on the outside of the housing and extending into the housing, an impeller rod disposed longitudinally and rotatably in the housing, a water pump disposed at the bottom of the housing, and a cooling channel disposed around the side wall of the housing;

[0007] The impeller rod is provided with blades and a dust removal component driven by air intake through the air intake pipe from top to bottom. The dust removal component is composed of several filter plates arranged around the impeller rod.

[0008] The water pump includes a pump casing, a pump shaft that is longitudinally and rotatably mounted inside the pump casing via bearings, and a water impeller that is coaxially and fixedly mounted on the pump shaft; the water impeller is rotatably and sealed to the inner wall of the pump casing, the top of the pump shaft is rotatably sealed and penetrates the pump casing and is fixedly connected to the impeller rod; the water pump inlet is connected to a cold water source, and the water outlet is connected to the inlet pipe of the cooling channel.

[0009] Explanation: When gas enters through the inlet pipe, the airflow drives the impeller rod to rotate. The impeller rod drives the water pump shaft to rotate through the central shaft. Water is pumped through the rotating water wheel, thereby pumping the cooling water in the refrigerator into the cooling channel. At the same time, the gas passes through the rotating filter plate to remove dust.

[0010] Furthermore, the housing has an internal cavity, the cooling channel is disposed in the cavity, a temperature sensor is provided on the inner side wall of the housing, the air outlet pipe is located on the side wall of the housing, the air inlet pipe is located on the top of the housing, the air outlet pipe and the air inlet pipe are also connected by a circulation pipe, the circulation pipe is provided with an air pump and a one-way control valve, and both the outer ports of the air inlet pipe and the air outlet pipe are provided with an electric control valve.

[0011] Description: Through the coordinated control of temperature sensors, circulation pipes, air pumps, and electronically controlled valves, dynamic temperature regulation and airflow circulation optimization are achieved. Under high temperature conditions, it automatically switches to internal circulation mode to avoid the input of new hot air and accelerate cooling. After cooling down, it accurately switches to exhaust mode, significantly improving the system's temperature control response speed and operational stability, reducing cooling energy consumption, and achieving safe, energy-saving, and intelligent integrated dust removal and cooling.

[0012] Furthermore, a dust cover is provided on the inner wall of the housing, and a sliding door for replacing the filter plate and dust cover is provided at the bottom of the housing.

[0013] Note: The dust cover prevents residual dust on the filter plate from escaping through the exhaust pipe. The bottom pull-door design allows for quick replacement of the filter plate and dust cover without disassembling the outer casing, significantly shortening the maintenance cycle, ensuring continuous dust removal effect, and significantly improving the safety of equipment operation and the convenience of maintenance.

[0014] Furthermore, the cooling channel has a spiral structure and a circular longitudinal section; a cooler is provided on one side of the housing, the water outlet of the cooling channel is connected to the water inlet of the cooler, and the water outlet of the cooler is connected to the water inlet of the water pump.

[0015] Explanation: The circular cross-section provides a uniform radial water flow distribution, and the circumferential symmetry reduces local flow dead zones, ensuring full circumferential contact between the cooling water and the high-temperature wall surface of the inner shell; at the same time, the fluid resistance of the circular channel is lower than that of the irregular cross-section, which can reduce the power consumption of the water pump, balancing cooling efficiency and operating economy.

[0016] Furthermore, the spiral direction of the cooling channel is opposite to the rotation direction of the impeller rod inside the inner shell.

[0017] Explanation: This design utilizes a counter-current heat exchange mechanism created by the opposing spiral directions of the interlayered water flow and the rotating gas. The spiral direction of the cooling channel is opposite to the impeller shaft's rotation direction. As the cooling water flows along the trapezoidal cross-section channel, the centrifugal force generated by the reverse spiral counteracts the pressure field created by the gas vortex, forcing the water flow to adhere closely to the high-temperature wall of the inner shell. Although the interlayered water flow and the inner gas do not directly mix, the reverse spiral arrangement significantly improves the conduction heat exchange efficiency by enhancing the temperature gradient at the shell wall—that is, the water flow sweeps across the high-temperature wall against the gas rotation direction. Simultaneously, it avoids localized heat accumulation caused by unidirectional flow. Therefore, this design maximizes heat transfer driven by temperature difference.

[0018] Furthermore, the cooling channel has a spiral structure and a trapezoidal longitudinal section. The height of the trapezoidal section is 10-15mm, and the width of the upper base is 1 / 2-2 / 3 of the width of the lower base.

[0019] Explanation: The trapezoidal inclined sidewalls disrupt the laminar flow of water, creating localized turbulence, thereby increasing the contact frequency between the fluid and the channel wall and improving heat transfer efficiency. The asymmetrical upper and lower bases of the trapezoid, i.e., the narrower top and wider bottom structure, guide the water flow to cover the entire channel cross-section more evenly, avoiding the low-velocity areas at the edges of traditional rectangular or circular channels. The geometric feature of being narrower at the top and wider at the bottom also enhances the peeling of the boundary layer on the wall, increasing the convective heat transfer coefficient in high-temperature areas, making it particularly suitable for the rapid cooling requirements of high-temperature flue gas. At the same time, the mechanical strength of the trapezoidal structure is superior to that of a circular cross-section, allowing it to withstand higher thermal stress on the shell.

[0020] The beneficial effects of this utility model are as follows: Through the linkage design of the impeller rod and the water pump shaft, the impeller rotation is driven by the intake airflow to achieve self-powered water-cooled circulation. Through the synergistic effect of the jacketed cooling channel and the rotating filter plate, gas cooling is completed simultaneously during the dust removal process. This design can integrate dust removal and cooling functions into one unit, achieving efficient heat energy exchange without external power. The centrifugal force field formed by the rotating filter plate can also enhance dust separation efficiency. The water-cooled jacket structure can effectively reduce the temperature of hot air and equipment operation, and has comprehensive advantages such as energy saving and consumption reduction, simultaneous dust removal and cooling, compact structure and low maintenance cost.

[0029] The central shaft of the impeller rod 5 is fixedly connected to the rotating shaft of the water pump 6; the cooling channel 21 has a spiral structure and a circular longitudinal section; a cooler 7 is provided on one side of the housing 1, the water outlet pipe of the cooling channel 2 is connected to the water inlet of the cooler 7, and the water outlet of the cooler 7 is connected to the water inlet of the water pump 6.

[0030] like Figure 2 As shown, the housing 1 has an internal cavity, the cooling channel 2 is disposed in the cavity, the inner side wall of the housing 1 is provided with a temperature sensor 8, the air outlet pipe 4 is located on the side wall of the housing 1, the air inlet pipe 3 is located on the top of the housing 1, the air outlet pipe 4 and the air inlet pipe 3 are also connected by a circulation pipe 41, the circulation pipe 41 is provided with an air pump 411 and a one-way control valve 412, and the outer ports of the air inlet pipe 3 and the air outlet pipe 4 are both provided with an electric control valve;

[0033] The temperature sensor 8, air pump 411, one-way control valve 412, air inlet pipe 3 electric control valve and air outlet pipe 4 electric control valve are all electrically connected to the power supply; the one-way opening direction of the one-way control valve 412 is the branch direction from the branch of the air outlet pipe 4 to the branch of the air inlet pipe 3 inside the circulation pipe 41, which is the longitudinal direction from bottom to top inside the circulation pipe 41 in the figure.
