Description

Technical Field

[0001] This utility model relates to the field of vertical boiler technology, and in particular to a vertical environmentally friendly and energy-saving boiler. Background Technology

[0002] A boiler is a device that uses the heat energy released by the combustion of fuel and other heat energy to heat a working fluid to certain parameters. It is used in industrial production, heating, and power generation. Through efficient energy conversion, boilers can provide the hot water required for production processes, meet the heat energy needs of different industries, improve production efficiency, and improve people's living environment.

[0003] As a member of the boiler family, the vertical environmentally friendly and energy-saving boiler has a greater advantage in terms of space occupation compared with traditional boilers due to its vertical structure design. It is suitable for places with limited space. At the same time, it deeply integrates the concepts of environmental protection and energy conservation, aiming to reduce pollutant emissions and improve energy utilization efficiency, which meets the requirements of the current era of green development and provides clean and efficient heat energy supply solutions for various industries.

[0004] Traditional boilers suffer from reduced overall stability under prolonged exposure to high temperatures, pressures, and vibrations. To address this issue, existing technologies employ high-strength steel to enhance the high-temperature and pressure resistance of the supporting structure, ensuring stable boiler operation under harsh conditions. However, the heat exchange tubes are often arranged closely to maximize space utilization and meet heat exchange requirements. When flue gas enters the relatively narrow and densely packed heat exchange tube area from a wide flue, it encounters significant flow resistance. The flue gas tends to choose the path with less resistance through the gaps between the heat exchange tubes, resulting in concentrated flue gas flow around some heat exchange tubes while others do not receive sufficient flue gas flushing, leading to low heat exchange efficiency.

The support columns 10 play the role of supporting the chimney cover 9 to ensure the stable installation of the chimney cover 9. The top of multiple support columns 10 are fixedly connected to the same chimney cover 9. The chimney cover 9 can prevent rainwater and debris from entering the chimney pipe 5. Specifically, the sealing ring 11 of the cover 603 cooperates with the sealing groove 12 of the feed port box 602 to effectively prevent fuel leakage and the entry of outside air, ensuring combustion efficiency and safety. The support column 10 on the chimney pipe 5 firmly supports the chimney cover 9, and the chimney cover 9 blocks rainwater and debris from falling into the chimney pipe 5, avoiding damage to internal components and extending the service life of the equipment.

[0022] Working Principle: When the boiler is running, fuel is fed into the furnace 601 through the feed inlet box 602 and the box cover 603. The burner 604 is ignited and injects combustion-supporting gas into the furnace 601, allowing the fuel to burn fully and release a large amount of heat energy. The high-temperature flue gas generated by combustion enters multiple flue pipes 201 connected to it from the outer wall of the furnace 601. At this time, the threaded guide and disperser shaft 205 and the threaded guide cone 206 in the flue pipe 201 rotate under the drive of the flue gas. The threaded guide and disperser shaft 205 guides the flue gas to be evenly dispersed in the horizontal direction, while the threaded guide cone 206 guides the flue gas to flow downward and be evenly distributed in the flue pipe 201. This effectively avoids the flue gas from concentrating and passing through a portion of the heat exchange tube gaps due to flow resistance, reducing the situation where heat is not fully utilized and is discharged with the flue gas. This improves energy efficiency. Meanwhile, the water pump 702 delivers water through the delivery pipe 701 into the spiral heat exchange tube assembly 703. The spiral heat exchange tube assembly 703 increases the contact area and time between the water and the flue gas, allowing the water to fully absorb the heat from the flue gas, further improving the heat exchange efficiency and making fuller use of the energy released by fuel combustion, thus achieving energy saving. The heated water is output through the output pipe 704, realizing the heat exchange process. During this period, the protection mechanism 8 monitors the internal pressure of the boiler in real time. When the pressure sensor 801 detects an abnormal increase in pressure, the pressure relief valve 803 opens and the pressure is released through the pressure relief pipe 802 to ensure boiler safety. The flue gas that has undergone heat exchange enters the chimney pipe 5, and the uniform dispersion mechanism 2 makes the flue gas evenly flush the spiral heat exchange tube assembly 703 to improve the heat exchange efficiency and achieve energy saving. Furthermore, when the flue gas discharged from the boiler enters the guide pipe 301 through the chimney pipe 5, due to the inclined design of the guide plate 303, the flue gas flows on the guide plate 303 and then enters the filter cylinder 302. The filter cylinder 302 filters and intercepts impurities in the flue gas. The purified flue gas enters the guide pipe 301 from the filter cylinder 302 and returns to the chimney pipe 5 through the outlet groove 305 for discharge. When it is necessary to clean the filter cylinder 302, first unscrew the nut sealing cover 306 to release the seal on the top of the guide pipe 301, then unscrew the nut 3074 and pull the threaded pin 3073 out of the positioning block 3072 and the mounting base 3071. At this time, the filter cylinder 302 can be pulled out axially from the guide pipe 301 for cleaning and replacement. The design of the mounting component 307 ensures that the filter cylinder 302 is installed firmly and is easy to disassemble and maintain, ensuring that the filtration mechanism 3 can work continuously and stably, effectively improving the filtration effect of the chimney flue gas and the convenience of device maintenance.
