Description

Technical Field

[0001] This utility model belongs to the field of energy and thermal energy technology, and in particular relates to a gas-fired condensing low-NOx steam boiler. Background Technology

[0002] Gas-fired condensing low-NOx steam boilers are high-efficiency and energy-saving steam boilers that use gas as fuel and combine condensing and low-NOx technologies. Their main feature is that they can reduce emissions of pollutants such as nitrogen oxides while improving energy efficiency.

[0003] Gas-fired condensing low-NOx steam boilers typically burn a mixture of air and gas. However, this mixture may contain dust, oil mist, impurities, and other substances that can clog the equipment and affect its normal operation. Therefore, we have proposed a gas-fired condensing low-NOx steam boiler. Utility Model Content

[0004] The purpose of this invention is to provide a gas-fired condensing low-NOx steam boiler. The rotating shaft drives the stirring rod to rotate, which mixes the gas and air evenly. The rotating shaft also drives the fan to rotate and blow the mixed gas into the steam boiler, thus solving the problem of filtering the mixed gas after the air and gas are mixed.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a gas-fired condensing low-NOx steam boiler, including a support frame, a steam boiler slidably connected to the top of the support frame, a filter mechanism provided on the outer surface of the support frame, and an installation mechanism provided on the top of the steam boiler.

[0007] The filtration mechanism includes a fixed frame, a mixing tank fixedly connected to the outer surface of the fixed frame, a fixed body fixedly connected to the side of the fixed frame away from the steam boiler, a motor fixedly connected to the inner wall of the fixed body, a rotating shaft fixedly connected to the output shaft of the motor via a coupling, a gas pipe fixedly connected to the inner wall of the mixing tank, a scraper fixedly connected to the outer surface of the rotating shaft, a fan fixedly connected to the outer surface of the rotating shaft, a stirring rod fixedly connected to the outer surface of the rotating shaft, an installation arc slidably connected to the inner wall of the mixing tank, a connecting ring fixedly connected to the outer surface of the installation arc, a filter plate fixedly connected to the inner wall of the connecting ring, and bolts threadedly connected to the inner wall of the installation arc. Through the rotatable rotating shaft, the mixture of air and gas can be filtered, removing particulate matter and impurities from the gas mixture. This helps maintain the stable operation of combustion equipment, heat exchangers, and other systems, preventing system malfunctions caused by blockages or contamination.

[0008] Furthermore, the bottom of the fixed frame is fixedly connected to the outer surface of the support frame, the outer surface of the rotating shaft is rotatably connected to the inner wall of the mixing tank, and the outer surface of the scraper is in contact with the outer surface of the mixing tank.

[0009] Furthermore, the fan is located inside the mixing tank, a total of several stirring rods are provided, the outer surface of the connecting ring is slidably connected to the inner wall of the mixing tank, a total of several bolts are provided, and the outer surface of the bolts is threadedly connected to the inner wall of the mixing tank.

[0010] Furthermore, the installation mechanism includes a steam pipe fixedly connected to the inner wall of the steam boiler, a connecting pipe slidably connected to the outer surface of the steam pipe, and a retaining ring slidably connected to the outer surface of the connecting pipe.

[0011] Furthermore, two clamping arcs are provided. A sliding rod is fixedly connected to the side of the clamping arc away from the connecting pipe. A connecting block is fixedly connected to the top of the steam boiler. Two connecting blocks are provided. Through the clamping arcs that can clamp the connecting pipe, the steam boiler can be easily and conveniently connected to other devices, enabling the boiler to utilize fuel more efficiently and to use the recovered heat in other processes, thereby improving the overall system's energy utilization rate and reducing energy waste.

[0012] Furthermore, the inner wall of the connecting block is slidably connected to the outer surface of the sliding rod, and a spring is fixedly connected to the side of the locking arc away from the connecting tube, with the inner side of the spring sleeved with the outer surface of the sliding rod.

[0014] Furthermore, a threaded rod is threadedly connected to the inner wall of the L-shaped block, and a contact plate is fixedly connected to one end of the threaded rod near the connecting pipe. The outer surface of the contact plate is in contact with the outer surface of the sliding rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a rotating shaft that drives a fan to rotate. The fan blows air into the mixing tank to mix with the gas. The rotating shaft also drives a stirring rod to rotate, ensuring thorough mixing of the gas and air. Finally, the mixed gas is filtered by a filter plate before entering the steam boiler. The rotating shaft effectively filters the air and gas mixture, removing particulate matter and impurities. This helps maintain the stable operation of combustion equipment, heat exchangers, and other systems, preventing malfunctions caused by blockages or contamination.

[0017] 2. This utility model incorporates a retaining arc. The connecting pipe pushes the retaining arc away from each other, causing the retaining arc to slide within the connecting block. Simultaneously, the retaining arc compresses the spring. When the connecting pipe is properly positioned, the threaded rod is rotated. By clamping the connecting pipe with the retaining arc, the steam boiler can be easily and conveniently connected to other devices. This allows the boiler to utilize fuel more efficiently and reuse the recovered heat in other processes, thereby improving the overall system's energy efficiency and reducing energy waste.

[0031] One specific application of this embodiment is:

[0032] When the equipment is needed, gas is injected into the mixing tank 202 through the gas pipe 205. The motor 204 is then started, causing the rotating shaft 206 to rotate. The rotating shaft 206 then drives the scraper 207 to scrape across the mixing tank 202, preventing blockage of the air inlet. Simultaneously, the rotating shaft 206 also drives the fan 208 to rotate, blowing air into the mixing tank 202 to mix with the gas. The rotating shaft 206 also drives the stirring rod 209 to rotate, further mixing the gas and air. After thorough mixing, the final mixed gas is filtered by filter plate 212 before entering the steam boiler 102. This achieves the effect of filtering the air and gas mixture after mixing, removing particulate matter and impurities from the mixed gas. This helps maintain the stable operation of combustion equipment, heat exchangers, and other systems, preventing system malfunctions caused by blockages or contamination. When the filter plate 212 needs to be replaced, simply unscrew the bolt 213 from the steam boiler 102 and the mounting arc 210, and then pull the mounting arc 210 upwards. At this time, the mounting arc 210 will drive the connection... Ring 211 moves, and then connecting ring 211 will drive filter plate 212 to move out of mixing tank 202. At this time, filter plate 212 can be replaced. Steam produced by steam boiler 102 will be discharged through steam pipe 301. When steam boiler 102 is connected to other equipment, connecting pipe 302 will push the retaining arc 303 away from each other. At this time, retaining arc 303 will drive sliding rod 304 to slide in connecting block 306. At the same time, retaining arc 303 will also compress spring 305. When the installation position of connecting pipe 302 is appropriate, then... Rotating the threaded rod 308 causes the contact plate 309 to move closer together, bringing it into contact with the sliding rod 304. This causes the sliding rod 304 to engage the retaining arc 303 tightly against the connecting pipe 302, fixing its position. This allows for easy and convenient connection of the steam boiler 102 to other devices, enabling the boiler to utilize fuel more efficiently and recycle the recovered heat for other applications, thereby improving the overall system's energy efficiency and reducing energy waste.
