Description

Technical Field

[0001] This utility model relates to the field of boiler exhaust gas treatment technology, specifically a boiler exhaust gas heat exchange and utilization device. Background Technology

[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature steam, or organic heat carriers with a certain amount of thermal energy. In the combustion equipment section, fuel combustion continuously releases heat. The high-temperature flue gas produced by combustion transfers heat to the boiler's heating surfaces through heat transfer, reducing its own temperature, and is finally discharged through the chimney.

[0003] The prior art discloses a heat exchange and utilization device for low-pressure boiler exhaust gas, application number CN202320646637.2, which includes a base, a boiler body, and a conversion mechanism disposed on the side of the boiler body. The boiler body is fixedly connected to the surface of the base, and the conversion mechanism includes a conversion component and an auxiliary component. This utility model uses a transmission pipe. Because the transmission pipe is threaded and tightly attached to the conduit, the exhaust gas with heat will transfer heat to the transmission pipe when it flows inside the conduit. At this time, the cold water inside the transmission pipe will be gradually heated by the hot gas and discharged into the water tank through the outlet. The heat of the exhaust gas is used to heat the cold water, thereby realizing the utilization of heat. Subsequently, the exhaust gas will be discharged from the end of the conduit into the exhaust gas treatment equipment, where it will be treated and discharged through the flue gas outlet. The filter plate can filter out particulate matter in the exhaust gas, reducing air pollution.

[0004] The surface of the aforementioned conduit is wrapped with a transmission tube, and a water inlet is fixedly connected to the left end of the transmission tube. However, the water inlet is not equipped with a support device, which can easily cause the water inlet to fall off, resulting in the transmission tube being unable to effectively transport water.

An exhaust gas treatment device 2 is threadedly connected to the right side surface of the boiler body 4. A pipe is installed at the upper end of the boiler body 4 and threadedly connected to the upper end of the exhaust gas treatment device 2. A transmission pipe 12 is wound around the surface of the pipe. The pipe can transport the exhaust gas generated by the boiler body 4 into the interior of the exhaust gas treatment device 2 to treat the boiler exhaust gas. At the same time, when the pipe transports the exhaust gas, the pipe can heat the water resources in the transmission pipe 12. A storage device 1 is installed at the right end of the boiler body 4, and the fixed base 3 is fixedly connected to the bottom surface of the boiler body 4.

[0028] The storage device 1 includes a water inlet device 11, a transmission pipe 12, a support assembly 13, and a water storage tank 14. The support assembly 13 is installed at the left end of the transmission pipe 12, and the transmission pipe 12 is fixedly connected to the top surface of the water inlet device 11. The water inlet device 11 is installed on the top surface of the fixed base 3, and the water storage tank 14 is installed on the top surface of the fixed base 3. The water inlet device 11 is located to the left of the exhaust gas treatment device 2, and the water storage tank 14 is located to the left of the exhaust gas treatment device 2. The water storage tank 14 is installed on the inner wall surface of the water inlet device 11. There are four water storage tanks 14, and the four water storage tanks 14 are arranged in a rectangular shape.

[0029] The support assembly 13 includes a metal frame 131, a limiting plate 132, a metal vertical rod 133, a helical spring 134, a metal ring 135, a connecting block 136, and a limiting frame 137. The limiting plate 132 is threaded to the bottom surface of the metal frame 131 and the lower end of the metal vertical rod 133. The metal frame 131 is movably connected to the lower end of the metal vertical rod 133. Pushing the metal vertical rod 133 downwards allows it to insert into the left end of the metal frame 131. Pushing the limiting plate 132 upwards allows it to be threadedly connected to the lower end of the metal vertical rod 133, thus securing the metal frame 131 and the metal vertical rod 133 together. The limiting frame 137 is threaded to the top surface of the metal frame 131, which is threaded to the upper end of the boiler body 4. The connecting block 136 is fixedly connected to the top of the helical spring 134. On the surface, the metal vertical rod 133 is located inside the helical spring 134. A connector is installed at the upper end of the metal vertical rod 133. The connector is inserted into the upper end of the limiting frame 137. The connecting block 136 is threadedly connected to the left end of the metal ring 135. The metal ring 135 is movably connected to the left end of the transmission pipe 12. The connecting block 136 is movably connected to the left end of the transmission pipe 12. The connecting block 136 and the metal ring 135 are threadedly connected. The metal ring 135 and the connecting block 136 can fix the position of the transmission pipe 12 to prevent the transmission pipe 12 from falling. The connecting block 136 is slidably connected to the upper end of the metal vertical rod 133. A limiting threaded rod is fixedly connected to the top surface of the metal frame 131. The limiting threaded rod is inserted into the lower end of the limiting frame 137. The hexagonal nut and the limiting threaded rod can thread-fix the metal frame 131 and the limiting frame 137, making it convenient to disassemble and replace the limiting frame 137.

[0030] When in use, push the metal frame 131 into the upper end of the boiler body 4 to initially determine the position of the metal frame 131. Then, install the pipe on the upper end of the exhaust gas treatment equipment 2, and fix the pipe and the right side surface of the metal frame 131 with threads to determine the position of the metal frame 131 and the pipe.

[0031] The exhaust gas treatment device 2 is threaded at the other end of the pipe, and then a transmission pipe 12 is wrapped around the surface of the pipe, which can determine the position of the transmission pipe 12.

[0032] A water inlet device 11 is installed at the output end of the transmission pipeline 12. The water inlet device 11 has a right-side water storage tank 14 installed inside, which can store heated water.

[0033] Push the metal vertical rod 133 downwards, and the metal vertical rod 133 is inserted into the front end of the metal frame 131. Then push the limiting plate 132 upwards, so that the lower end of the limiting plate 132 and the metal vertical rod 133 are movably connected. Then turn to the nut, and the nut can fix the metal frame 131, the limiting plate 132 and the metal vertical rod 133 with threads.

[0034] Push the helical spring 134 downward to make the lower end of the helical spring 134 and the metal vertical rod 133 movably connected. Then push the connecting block 136 downward and slide it on the surface of the metal vertical rod 133 so that the bottom surface of the connecting block 136 and the top surface of the helical spring 134 are connected. Then rotate the nut so that the nut rotates on the threaded end surface of the metal vertical rod 133 and is connected to the top surface of the connecting block 136. The position of the connecting block 136 can be determined.

[0035] Push the metal ring 135 upward so that it slides at the left end of the transmission pipe 12. Then push the metal ring 135 upward so that the metal ring 135 and the connecting block 136 are threadedly connected, which can fix the metal ring 135 and the connecting block 136 with threads.

[0036] Pushing the threaded rod allows it to be inserted into the connection between the connecting block 136 and the metal ring 135, thus fixing the connecting block 136 and the metal ring 135 with threads, thereby determining the position of the transmission pipe 12.

[0037] Pushing the connector downwards allows it to be threadedly connected to the upper end of the metal vertical rod 133, thus determining the position of the connector. Pushing the limiting frame 137 downwards causes the top surface of the limiting frame 137 and the metal frame 131 to be threadedly fixed, while the surface of the limiting frame 137 and the connector is movably connected, thereby determining the position of the metal vertical rod 133 and thus the position of the transmission pipe 12.
