Description

Technical Field

[0001] The utility model belongs to the technical field of electric zinc furnace structure design, and in particular relates to an energy-saving electric zinc furnace structure. Background Art

[0002] As an important equipment for metal surface treatment, galvanizing furnace is widely used in many manufacturing industries such as construction, machinery, coal mining, chemical industry, electric power, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, etc. Through galvanizing treatment, the corrosion resistance of the metal surface can be effectively increased and its service life can be extended. However, the existing electric heating galvanizing furnace has several shortcomings in design and use.

[0003] The patent with application number 202321266870.4 discloses an energy-saving electric zinc furnace, including a furnace body, a smoke exhaust pipe, a heat exchange water tank and a sedimentation chamber. The furnace body is provided with a smoke hood. The smoke exhaust pipe includes a smoke inlet section and a smoke exhaust section. A heat exchange section is connected between the smoke inlet section and the smoke exhaust section. The heat exchange section is arranged in the heat exchange water tank. The smoke inlet section is connected to the smoke hood, and the smoke exhaust section is connected to the sedimentation chamber.

[0004] Although the above solution solves the problem in the prior art that the high-temperature flue gas generated by the electric zinc furnace causes the temperature of the pipeline to rise, which is prone to scalding accidents, and the high temperature of the flue gas is not conducive to the combination with water to settle, resulting in heat waste, it often directly discharges the water in the settling chamber after treating the flue gas, without achieving effective water recycling. This practice not only leads to a large amount of water resource consumption, but also increases the operating costs of the enterprise. Especially today when water resources are increasingly scarce, this unsustainable way of using water resources is obviously contrary to the requirements of environmental protection and sustainable development.

[0016] (2) The utility model improves the heat exchange efficiency and reduces the flue gas temperature by optimizing the smoke exhaust system.

DETAILED DESCRIPTION

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] See also Figures 1 to 4As shown, the embodiment of the utility model provides an energy-saving electro-zinc furnace structure, specifically including a bottom plate 1, the upper surface of the bottom plate 1 is fixedly connected with a furnace body 2 and a settling chamber 10, the outer surface of the settling chamber 10 is provided with a circulation mechanism 9, the upper surface of the furnace body 2 is fixedly connected with a first exhaust pipe 3, the end of the first exhaust pipe 3 away from the furnace body 2 is fixedly connected with a heat exchange pipe 4, the end of the heat exchange pipe 4 away from the first exhaust pipe 3 is fixedly connected with a second exhaust pipe 6, the outer surface of the first exhaust pipe 3 is fixedly connected with a heat exchange box 5, the second exhaust pipe 6 is fixedly connected to the inside of the heat exchange box 5, and the upper surface of the heat exchange box 5 is installed with a second chiller 14. The upper surface of the heat exchange box 5 is fixedly connected with a water supply pipe 11, the bottom surface of the heat exchange box 5 is fixedly connected with a first drain pipe 12, the outer surface of the first drain pipe 12 is installed with a first electric valve 13, and the inner bottom wall of the heat exchange box 5 is installed with a second temperature sensor 15. The right end of the second smoke exhaust pipe 6 is fixedly connected to the smoke exhaust fan tube 7, and the right side of the smoke exhaust fan tube 7 is fixedly connected to the third smoke exhaust pipe 8. The end of the third smoke exhaust pipe 8 away from the smoke exhaust fan tube 7 is fixedly connected to the smoke distribution plate 16, and a group of smoke distribution holes 17 are opened inside the smoke distribution plate 16. The third smoke exhaust pipe 8 is fixedly connected to the inside of the settling chamber 10. The outer surface of the settling chamber 10 is fixedly connected to the second drain pipe 18, and the outer surface of the second drain pipe 18 is installed with a second electric valve 19. The upper surface of the settling chamber 10 is installed with an air filter 20. The outer surfaces of the first smoke exhaust pipe 3, the second smoke exhaust pipe 6, and the third smoke exhaust pipe 8 are all wrapped with mineral wool felt, which can insulate the smoke exhaust pipe.

[0024] Specifically in this embodiment, during the galvanizing process, the high-temperature flue gas generated in the furnace body is discharged through the first smoke exhaust pipe 3. The high-temperature flue gas first enters the heat exchange pipe 4, exchanges heat with the cold water in the heat exchange box 5, reduces the temperature of the flue gas and preheats the cold water. The flue gas after heat exchange continues to enter the smoke exhaust fan tube 7 through the second smoke exhaust pipe 6, is driven by the smoke exhaust fan, and enters the smoke equalizing plate 16 through the third smoke exhaust pipe 8. The smoke equalizing holes 17 in the smoke equalizing plate ensure that the smoke is evenly distributed, slow down the smoke flow rate, and further reduce its temperature. Finally, the smoke enters the settling chamber 10, and the particulate matter in the smoke settles down in the settling chamber. By optimizing the smoke exhaust system, the heat exchange efficiency is improved and the smoke temperature is reduced. The high-temperature smoke first exchanges heat with the cold water in the heat exchange box 5 through the heat exchange tube 4 to reduce the smoke temperature. Then, the smoke enters the smoke equalizing plate 16, and the smoke equalizing holes 17 ensure that the smoke is evenly distributed, and the smoke flow rate is slowed down to further reduce its temperature. This design not only improves the heat exchange efficiency and effectively utilizes the heat in the smoke, but also reduces the smoke temperature and reduces the thermal pollution to the environment during the smoke exhaust process. At the same time, it also helps the sedimentation of particulate matter in the settling chamber 10, thereby improving the purification effect of the smoke.

[0025] See also Figures 1 to 4As shown, the circulation mechanism 9 specifically includes a first chiller 901, a filter element 905, and a first temperature sensor 906. The first chiller 901 is installed on the outer surface of the sedimentation chamber 10. The output end of the first chiller 901 is fixedly connected with a water spray pipe 902. The end of the water spray pipe 902 away from the first chiller 901 is fixedly connected with a nozzle 903. The nozzle 903 is fixedly connected to the inner wall of the sedimentation chamber 10. The input end of the first chiller 901 is fixedly connected with a water pumping pipe 904. The water pumping pipe 904 is fixedly connected to the bottom surface of the sedimentation chamber 10. The filter element 905 and the first temperature sensor 906 are both installed on the inner bottom wall of the sedimentation chamber 10.

[0026] In this embodiment, by setting up a circulation mechanism 9, the recycling of water resources is achieved. Specifically, the first chiller 901 draws cooling water that has undergone preliminary sedimentation from the bottom of the sedimentation chamber 10, and after filtering through the filter element 905, it is re-sprayed into the sedimentation chamber 10 by the water spray pipe 902 and the nozzle 903 to form a water curtain to further cool and purify the flue gas. This design not only reduces the consumption of water resources and reduces the operating costs of the enterprise, but also meets the requirements of environmental protection and sustainable development. It is of great significance to the current situation of increasingly tight water resources.

[0027] The specific working principle of the utility model is as follows: During the galvanizing process, the high-temperature flue gas generated in the furnace body is discharged through the first smoke exhaust pipe 3. The high-temperature flue gas first enters the heat exchange tube 4, exchanges heat with the cold water in the heat exchange box 5, reduces the temperature of the flue gas and preheats the cold water. The flue gas after heat exchange continues to enter the smoke exhaust fan tube 7 through the second smoke exhaust pipe 6, driven by the smoke exhaust fan, and enters the smoke equalizing plate 16 through the third smoke exhaust pipe 8. The smoke equalizing holes 17 in the smoke equalizing plate ensure that the smoke is evenly distributed, and slow down the flow rate of the smoke, further reducing its temperature. Finally, the smoke enters the settling chamber 10. In the settling chamber, the particulate matter in the smoke settles down, and the purified gas is discharged into the atmosphere through the smoke exhaust system. The circulation mechanism 9 is the key to energy saving. The first chiller 901 draws the cooling water that has undergone preliminary sedimentation from the bottom of the settling chamber 10 through the pumping pipe 904, and after being filtered by the filter element 905, it is re-circulated by the water spray pipe 902 and the nozzle 903. It is sprayed into the settling chamber to form a water curtain to further cool and purify the flue gas. The first chiller 901 is also responsible for maintaining the temperature of the circulating water to ensure the heat exchange efficiency. The second chiller 14 is used to further cool the water in the heat exchange box 5 to form a closed-loop cooling system. The heat in the circulating water can be recycled through the heat exchange system, such as for preheating production water or other process requiring heating. The heat exchange box 5 and the settling chamber 10 are respectively installed with a second temperature sensor 15 and a first temperature sensor 906 to monitor the water temperature in real time to ensure the heat exchange efficiency and the stability of the water cycle. By controlling the opening and closing of the first electric valve 13 and the second electric valve 19, drainage can be carried out. The mineral wool felt wrapped around the outer surfaces of the first smoke exhaust pipe 3, the second smoke exhaust pipe 6, and the third smoke exhaust pipe 8 effectively isolates high temperature and prevents scalding accidents. The air filter 20 is installed on the upper surface of the settling chamber to further purify the exhaust gas and reduce environmental pollution.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
