Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas boiler technology, specifically to a whitening elimination device for a gas boiler. Background Technology
[0002] Gas-fired boilers include gas-fired hot water boilers, gas-fired hot water boilers, and gas-fired steam boilers. Among them, gas-fired hot water boilers are also called gas-fired heating boilers and gas-fired bathing boilers. As the name suggests, gas-fired boilers refer to boilers that use gas as fuel. Compared with oil-fired boilers and electric boilers, gas-fired boilers are the most economical, so most people choose gas-fired boilers as boiler equipment for steam, heating, and bathing.
[0003] Gas-fired boilers require de-whitening during operation, which involves eliminating harmful white flue gas. Conventional measures include flue gas cooling, electrostatic precipitators, wet desulfurization, and multi-stage filtration. When using flue gas cooling equipment to de-whiten flue gas, the flue gas flows through heat-conducting plates or sheets. The heat-conducting plates dissipate heat, thereby cooling the flue gas. After prolonged use, impurities from the flue gas accumulate on the surface of the heat-conducting plates, forming barriers on the surface. This reduces the heat transfer efficiency between the heat-conducting plates and the flue gas, resulting in poor de-whitening effects. Therefore, it is necessary to clean the surface of the heat-conducting plates.
[0004] In existing flue gas cooling and whitening devices, the cleaning process for the heat-conducting plate surface is quite troublesome, and the whitening device needs to be stopped during the cleaning process, which affects work efficiency.
[0005] Therefore, this utility model provides a whitening elimination device for a gas-fired boiler to solve the above-mentioned problems. Utility Model Content
[0006] In view of the above situation and to overcome the defects of the prior art, this utility model provides a whitening device for a gas boiler to solve the above problems.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] A device for eliminating white pollution in a gas-fired boiler includes a shell and heat-conducting pipes;
[0009] Housing: A spray assembly is installed inside the upper end of the housing, a smoke outlet is provided on the upper side of the housing, a smoke pipe passes through the lower end of the housing, and a wastewater carrying frame is placed inside the lower end of the housing, with the wastewater carrying frame located below the smoke pipe;
[0010] Heat pipe: The heat pipe rotates inside the outer shell. The heat pipe is arranged in a linear array inside the outer shell. The heat pipe is located between the smoke pipe and the spray assembly. A guide plate is fixed inside the lower end of the outer shell. The guide plate is located between the heat pipe and the smoke pipe. The guide plate has a linear array of guide holes. The guide holes are located directly below the middle of two adjacent smoke pipes. The width of the guide holes is equal to the rotation distance of the lower end of the heat pipe.
[0011] Through the above technical solution, the guide holes of the guide plate can guide the flue gas to the space between the two heat pipes. The outer surface of the spray assembly and the heat pipes can cool the flue gas and complete the whitening work. The heat pipes can rotate, and the flue gas floats upward, so the two sides of the heat pipes can alternately tilt downward, thereby allowing the two sides of the heat pipes to alternately contact the flue gas and cool it down. The upward-facing side of the heat pipes can receive water or cleaning liquid sprayed by the spray assembly, thereby cleaning the upward-facing side of the heat pipes. That is, the two sides of the heat pipes are cleaned alternately.
[0012] Preferably, the spray assembly includes an inlet pipe, a support frame, a support shell, spray nozzles, a spray pipe, a diverter box, a guide pipe, and a motor. The support frame is fixed in a circular array inside the shell, and a support shell is fixed between the support frames. A diverter box is rotatably mounted inside the upper end of the support shell. A motor is fixed inside the support shell, and the output end of the motor is fixed at the lower center of the diverter box. A spray pipe passes through a circular array on the side of the diverter box. Spray nozzles are arranged in a straight array on the upper side of the spray pipe. The spray nozzles are inclined relative to the vertical plane. A guide pipe passes through the upper center of the diverter box. An inlet pipe passes through the upper side of the shell, and the upper end of the guide pipe rotates inside the inlet pipe.
[0013] Through the above technical solution, water can be sprayed outward after passing through the water inlet pipe, water guide pipe, diversion box, spray pipe and spray nozzle to spray the flue gas. The diversion box can rotate and the spray nozzle is angled, which can make the sprayed water be thrown out at high speed and can also make the spray pipe disturb the flue gas, thereby ensuring that the water droplets fully contact the flue gas and improve the cooling effect on the flue gas.
[0014] Preferably, a second rotating shaft is fixed to the middle side of the heat pipe, the second rotating shaft rotates inside the outer shell, the heat pipe rotates inside the outer shell through the second rotating shaft, and a first rotating shaft is fixed to the end of the heat pipe, and the other ends of a row of first rotating shafts rotate on the side of the connecting plate.
[0015] The above technical solution allows a row of heat pipes to rotate simultaneously.
[0016] Preferably, the side of the outer casing has a cabinet door that rotates via hinges;
[0017] Using the above technical solution, the cabinet door can be opened to inspect or repair the internal parts of the outer shell.
[0018] Preferably, an external connecting pipe passes through the side of the outer shell away from the cabinet door, and an internal insert pipe passes through the side of the wastewater carrying frame away from the cabinet door, with the internal insert pipe movably inserted inside the external connecting pipe;
[0019] With the above technical solution, the wastewater carrying frame can hold wastewater, which can be discharged from the inner pipe and the outer connecting pipe. The cabinet door can be opened to pull out the wastewater carrying frame for cleaning.
[0020] The beneficial effects of this utility model are as follows:
[0021] In summary, this device utilizes the guide holes in the guide plate to direct flue gas between two heat pipes. The spray assembly and the outer surface of the heat pipes can cool the flue gas, completing the whitening process. The heat pipes are rotatable, and since the flue gas rises, both sides of the heat pipes can alternately face downwards, allowing them to contact the flue gas in turn and cool it down. The upward-facing side of the heat pipes can receive water or cleaning fluid sprayed from the spray assembly, thus cleaning that side. Cleaning is convenient, and the alternating cleaning and operation of both sides of the heat pipes eliminates the need for machine shutdown, resulting in high efficiency. Attached Figure Description

[0030] The following will refer to the attached reference. Figures 1 to 7 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.
[0031] As attached Figure 1 - Appendix Figure 7 As shown, a whitening elimination device for a gas-fired boiler includes an outer shell 2 and a heat-conducting pipe 5;
[0032] Outer shell 2: A spray assembly is installed inside the upper end of the outer shell 2. A smoke outlet is provided on the upper side of the outer shell 2. A smoke spray pipe 10 passes through the lower end of the outer shell 2 in a straight array. Smoke nozzles are arranged in a straight array on the upper half of the smoke spray pipe 10 to ensure that the high-temperature smoke rises evenly. A wastewater carrying frame 11 is placed inside the lower end of the outer shell 2. A cabinet door 1 is rotated on the side of the outer shell 2 via a hinge. An external connecting pipe 12 passes through the side of the outer shell 2 away from the cabinet door 1. An internal insertion pipe 19 passes through the side of the wastewater carrying frame 11 away from the cabinet door 1. The internal insertion pipe 19 is movably inserted into the external connecting pipe 12. The wastewater carrying frame 11 is located below the smoke spray pipe 10.
[0033] Heat pipe 5: A second rotating shaft 8 is fixed to the middle side of the heat pipe 5. The second rotating shaft 8 rotates inside the outer shell 2. The heat pipe 5 rotates inside the outer shell 2 through the second rotating shaft 8. The heat pipe 5 is arranged in a straight line inside the outer shell 2. A first rotating shaft 6 is fixed to the end of the heat pipe 5. The other end of a row of first rotating shafts 6 rotates to the side of the connecting plate 7. The heat pipe 5 is located between the smoke pipe 10 and the spray assembly. A guide plate 9 is fixed inside the lower end of the outer shell 2. The guide plate 9 is located between the heat pipe 5 and the smoke pipe 10. A guide hole 20 is arranged in a straight line inside the guide plate 9. The guide hole 20 is located directly below the middle of two adjacent smoke pipes 10. The width of the guide hole 20 is equal to the rotation distance of the lower end of the heat pipe 5. That is, after the smoke pipe 10 rotates in the forward or reverse direction, the guide hole 20 can still be located directly below the middle of two adjacent smoke pipes 10.
[0034] In this embodiment, the spray assembly includes an inlet pipe 4, a support frame 13, a support shell 14, spray nozzles 15, a spray pipe 16, a diversion box 17, a guide pipe 18, and a motor 21. The support frame 13 is fixed in a circular array inside the outer shell 2. The support shell 14 is fixed between the support frames 13. The diversion box 17 rotates inside the upper end of the support shell 14. The motor 21 is fixed inside the support shell 14. The output end of the motor 21 is fixed at the lower center of the diversion box 17. The spray pipe 16 passes through the circular array on the side of the diversion box 17. The spray nozzles 15 are arranged in a straight array on the upper side of the spray pipe 16. The spray nozzles 15 are inclined relative to the vertical plane. The guide pipe 18 passes through the upper center of the diversion box 17. The inlet pipe 4 passes through the upper side of the outer shell 2. The upper end of the guide pipe 18 rotates inside the inlet pipe 4.
[0035] A controller 3 is fixed to the side of the outer casing 2. The input end of the controller 3 is electrically connected to an external power source, and the output end of the controller 3 is electrically connected to the motor 21.
[0036] The working principle of this device is as follows:
[0037] High-temperature flue gas passes sequentially through the smoke pipe 10, the guide hole 20, the middle of the two heat pipes 5, the upper end of the outer shell 2, and the smoke outlet of the outer shell 2.
[0038] Water or cleaning fluid is sprayed out after passing through the inlet pipe 4, the guide pipe 18, the diversion box 17, the spray pipe 16 and the spray nozzle 15 in sequence. The controller 3 controls the motor 21 to be powered on and work. The motor 21 drives the diversion box 17 to rotate, which causes the water or cleaning fluid to be thrown out at high speed from the spray nozzle 15. The sprayed water or cleaning fluid is sprayed onto the side and inside of the heat pipe 5 to cool the heat pipe 5. The flue gas flows from bottom to top, so the downward-sloping surface of the heat pipe 5 contacts the flue gas. Impurities in the flue gas will adhere to the downward-sloping surface of the heat pipe 5. The wastewater flows into the wastewater carrying frame 11 and then flows out from the inner insertion pipe 19 and the outer connecting pipe 12.
[0039] After prolonged operation, rotate the heat pipe 5 so that the downward-sloping side of the heat pipe 5 is rotated to the upward-sloping side, and the upward-sloping side of the heat pipe 5 is rotated to the downward-sloping side. This allows the side that was originally covered with impurities to be rotated to the upward-sloping side, where it is cleaned by the cleaning liquid and water. Meanwhile, the side that was originally cleaned rotates to the downward-sloping side, where it begins to come into contact with the flue gas, thus cooling the flue gas.
