Description

Technical Field

[0001] This utility model relates to the field of energy utilization technology, specifically to a high-efficiency waste heat power generation high-temperature energy conversion device for the cement industry. Background Technology

[0002] For example, a high-temperature energy conversion device for waste heat power generation in the cement industry, as disclosed in patent publication number CN222438540U, includes a waste heat power generation boiler body, a waste heat power generation energy conversion tube assembly, and a waste heat power generation energy conversion voltage stabilization system assembly. The waste heat power generation energy conversion voltage stabilization system assembly is communicatively connected to the waste heat power generation boiler body and the waste heat power generation energy conversion tube assembly via a communication cable or WiFi connection. The heat exchange coil and the air inlet connection pipe are arranged in a surrounding contact pattern for heat exchange, minimizing the heat exchange contact area. Flue gas from the cement plant enters the heat exchange coil through different pipes. When the flue gas flow decreases, the outer pipes automatically close, concentrating heat into the inner pipes and reducing unnecessary energy consumption. This allows for control over the stability of power generation, ensuring timely power supply, achieving high-temperature energy conversion voltage stabilization operation, improving power generation efficiency and stability, increasing energy utilization efficiency, and reducing energy consumption and environmental pollution.

[0003] However, during the use of the above-mentioned equipment, due to the setting of its internal waste heat power generation transducer tube assembly, the large amount of dust contained in the cement flue gas can easily cause blockage when it directly enters the waste heat power generation transducer tube, affecting its use. Therefore, in order to address this situation, we propose a more convenient and practical transducer device to meet the usage requirements. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency waste heat power generation high-temperature energy conversion device for cement industry, comprising a connecting funnel, wherein multiple equidistant fixing blocks are fixedly connected to the outer wall of the connecting funnel, a filtering mechanism is provided on one side of the connecting funnel, the filtering mechanism includes a filter tube, multiple equidistant connecting blocks are fixedly connected to the outer wall of the filter tube, the connecting blocks and the fixing blocks are connected to each other, a flow equalization plate is fixedly connected to one end of the filter tube, mounting blocks are fixedly connected to the inner walls of both sides of the filter tube, a mounting plate is fixedly connected to the top of the mounting block, a filter assembly is provided on one side of the mounting plate, and an energy conversion mechanism is provided on one side of the filtering mechanism.

[0006] Furthermore, the filter assembly includes a rotating tube, which is rotatably connected to a mounting plate. A first filter plate is fixedly connected to the outer wall of the rotating tube, a rotating rod is rotatably connected to the inner wall of the rotating tube, and a second filter plate is fixedly connected to the outer wall of the rotating rod.

[0007] Furthermore, a first bevel gear is fixedly connected to one end of the rotating tube, a second bevel gear is fixedly connected to one end of the rotating rod, and a third bevel gear is provided on the top of the mounting plate.

[0009] Furthermore, the transducer includes an air inlet pipe and a connecting pipe that are adapted to each other. One end of the air inlet pipe is fixedly connected to a heat exchange coil, and one side of the heat exchange coil is fixedly connected to a connecting pipe.

[0010] Furthermore, an exhaust pipe is fixedly connected to the other end of the heat exchange coil, and a lower connecting plate and an upper connecting plate are respectively installed on the outer wall of the heat exchange coil.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This high-efficiency waste heat power generation high-temperature energy conversion device for the cement industry, through the setting of a filtration mechanism and an energy conversion mechanism, allows waste gas to first enter the connecting funnel and connecting pipe during operation. Then, the solenoid valve opens and the waste gas flows into the connected filter pipe. After entering the filter pipe, the flow equalization plate evenly distributes the waste gas. Next, the waste gas passes through the mounting plate, and at the same time, the motor drives the third bevel gear to rotate, thereby driving the first and second bevel gears to rotate.

It is highly practical and suitable for widespread application.

[0012] Meanwhile, the energy conversion mechanism can increase the contact area and contact time between the exhaust gas and the working fluid, improve the heat exchange efficiency, and thus more effectively convert the waste heat of the exhaust gas into usable energy, thereby improving the efficiency of waste heat power generation.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In the cement production process, energy conversion equipment is required. The energy conversion equipment provided by this utility model is specifically designed for high-temperature waste gas energy conversion in cement production. During the energy conversion operation of this equipment, regular inspection and maintenance are necessary, especially for the filter plates in the filtration mechanism 3, which should be cleaned or replaced regularly to prevent clogging and affecting the filtration effect. Simultaneously, the working status of components such as the solenoid valve 5 and heat exchange coil 702 should be checked to ensure normal operation. During energy conversion, the temperature of the high-temperature waste gas must be strictly controlled. Excessively high temperatures may damage the equipment, while excessively low temperatures may affect the energy conversion effect. Therefore, the waste gas temperature should be adjusted according to the actual situation to ensure the equipment operates within a suitable temperature range. During the heat exchange process, a suitable medium should be selected for heat exchange. The type, flow rate, and temperature of the medium should be adjusted according to the actual situation to ensure optimal heat exchange performance.

[0017] like Figures 1-3As shown, this utility model provides a technical solution: a high-efficiency waste heat power generation high-temperature energy conversion device for cement industry, including a connecting ring 1, a plurality of equidistant fixing blocks 2 fixedly connected to the outer wall of the connecting ring 1, a filter mechanism 3 provided on one side of the connecting ring 1, the filter mechanism 3 including a filter tube 301, a plurality of equidistant connecting blocks 302 fixedly connected to the outer wall of the filter tube 301, the connecting blocks 302 and the fixing blocks 2 being connected to each other, a flow equalization plate 303 fixedly connected to one end of the filter tube 301, mounting blocks 304 fixedly connected to the inner walls of both sides of the filter tube 301, a mounting plate 305 fixedly connected to the top of the mounting block 304, a filter assembly provided on one side of the mounting plate 305, an energy conversion mechanism 7 provided on one side of the filter mechanism 3, a connecting pipe 4 fixedly connected to one end of the connecting ring 1, a solenoid valve 5 installed on the outer wall of the connecting pipe 4, and a connecting flange 6 fixedly connected to one end of the connecting pipe 4.

[0018] like Figure 2 As shown, the filter assembly includes a rotating tube 306, which is rotatably connected to a mounting plate 305. A first filter plate 307 is fixedly connected to the outer wall of the rotating tube 306, and a rotating rod 308 is rotatably connected to the inner wall of the rotating tube 306. A second filter plate 309 is fixedly connected to the outer wall of the rotating rod 308. A first bevel gear 310 is fixedly connected to one end of the rotating tube 306, and a second bevel gear 311 is fixedly connected to one end of the rotating rod 308. A third bevel gear 312 is provided on the top of the mounting plate 305. The teeth of the first bevel gear 310, the second bevel gear 311, and the third bevel gear 312 mesh with each other.

[0019] It should be noted that during use, the exhaust gas first enters the connecting funnel and connecting pipe 4, and then the solenoid valve 5 opens to flow into the connected filter pipe 301. After the exhaust gas enters the filter pipe 301, the flow equalization plate 303 makes the exhaust gas evenly distributed. Then the exhaust gas passes through the mounting plate 305. At the same time, the motor drives the third bevel gear 312 to rotate, thereby driving the first bevel gear and the second bevel gear 311 to rotate. The rotation of the first bevel gear and the second bevel gear 311 drives the rotating pipe 306, the rotating rod 308, and the first filter plate 307 and the second filter plate 309 to filter the exhaust gas and intercept dust and particulate impurities. When the filter mechanism 3 needs maintenance, replacement of filter components, or cleaning, there is no need to disassemble the entire device on a large scale, which greatly reduces maintenance costs and time.

[0020] like Figure 3 As shown, the transducer 7 includes an air inlet pipe 701, which is adapted to the connecting pipe 4. One end of the air inlet pipe 701 is fixedly connected to a heat exchange coil 702, and one side of the heat exchange coil 702 is fixedly connected to a connecting pipe 703. The other end of the heat exchange coil 702 is fixedly connected to an exhaust pipe 706. A lower connecting plate 704 and an upper connecting plate 705 are respectively installed on the outer wall of the heat exchange coil 702.

[0021] It is important to note that during operation, the filtered clean exhaust gas first flows into the heat exchange coil 702 through the inlet pipe 701. As it flows within the heat exchange coil 702, the high-temperature exhaust gas transfers a large amount of heat it carries to the working fluid, such as water or steam, within the coil, raising the temperature of the working fluid and achieving heat exchange. Under the action of the connecting pipe 703, the working fluid circulates within the heat exchange coil 702. After releasing heat, the exhaust gas is discharged through the exhaust pipe 706. The working fluid that has absorbed heat can be used in subsequent energy utilization processes such as power generation. The energy conversion mechanism 7 can increase the contact area and contact time between the exhaust gas and the working fluid, improving heat exchange efficiency and thus more effectively converting the waste heat of the exhaust gas into usable energy, thereby improving the efficiency of waste heat power generation.

[0022] During operation, the exhaust gas first enters the connecting funnel and connecting pipe 4. Then, the solenoid valve 5 opens, allowing the gas to flow into the connected filter pipe 301. After entering the filter pipe 301, the flow equalization plate 303 distributes the exhaust gas evenly. Next, the exhaust gas passes through the mounting plate 305. Simultaneously, the motor drives the third bevel gear 312 to rotate, which in turn drives the first bevel gear and the second bevel gear 311 to rotate. The rotation of the first bevel gear and the second bevel gear 311 drives the rotating pipe 306, the rotating rod 308, and the first filter plate 307 and the second filter plate 309 to filter the exhaust gas, intercepting dust and particulate impurities. The filtered clean exhaust gas first flows from the inlet... The gas flows into the heat exchange coil 702 through the gas pipe 701. As it flows within the heat exchange coil 702, the high-temperature exhaust gas transfers a large amount of heat it carries to the working fluid, such as water or steam, within the coil, raising the temperature of the working fluid and achieving heat exchange. Under the action of the connecting pipe 703, the working fluid circulates within the heat exchange coil 702. After releasing heat, the exhaust gas is discharged through the exhaust pipe 706. The working fluid that has absorbed heat can be used for subsequent energy utilization processes such as power generation. This device can effectively intercept dust, particles, and other impurities in the exhaust gas during cement production, reducing the risk of blockage of components such as the heat exchange coil 702 in the subsequent energy exchange mechanism 7.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
