Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology, and in particular to an exhaust gas treatment structure for a reverberatory furnace. Background Technology

[0002] A reverberatory furnace, also known as a flame reverberatory furnace, is a metallurgical furnace that directly heats materials with a flame to smelt metals. It consists of three main parts: a combustion chamber, a smelting chamber, and an exhaust flue (chimney).

[0003] Currently, mainstream designs focus solely on soot adsorption, removing particulate pollutants from exhaust gases by incorporating filter cotton and electrostatic adsorption plates in the adsorption box. However, there is a significant technological gap in the utilization of waste heat from exhaust gases. Exhaust gases typically carry a large amount of waste heat, which is directly adsorbed and then discharged, resulting in a waste of energy. Therefore, to better utilize the exhaust gases from reverberatory furnaces, promote technological progress in the industry, and enhance core technological competitiveness, this application proposes a new implementation scheme that differs from existing exhaust gas treatment structures for reverberatory furnaces. Utility Model Content

[0004] The purpose of this invention is to solve the problem of waste heat energy in existing reverberatory furnaces by proposing a tail gas treatment structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tail gas treatment structure for a reverberatory furnace includes a housing. An air inlet pipe is fixedly connected to the top of the housing, and an air outlet pipe is fixedly connected to the bottom of one side of the housing. A filter mechanism is provided inside the housing. Multiple heat-conducting pipes are inserted between the two sides of the housing. Both ends of the heat-conducting pipes are threaded with sealing caps. A water storage tank is fixed to one side of the outer wall of the housing by bolts. One end of the heat-conducting pipe passes through the water storage tank, and a water inlet pipe is fixedly connected to the top of the water storage tank.

[0007] Furthermore, the filtration mechanism includes a filter screen and a glass fiber absorbent cotton layer. A first mounting frame and a second mounting frame are slidably inserted into one side of the housing, and the filter screen and the glass fiber absorbent cotton layer are respectively disposed in the first mounting frame and the second mounting frame.

[0008] Furthermore, an observation window is provided on one side of the water storage tank, and a digital display bimetallic thermometer is sealed and inserted into the top of the water storage tank.

[0009] Furthermore, the bottom of the water storage tank is fixedly connected to an outlet pipe, and valves are provided on both the inlet and outlet pipes.

[0010] Furthermore, a sliding sleeve is slidably fitted onto the heat-conducting pipe, a scraper is integrally formed inside the sliding sleeve, a connecting plate is fixedly connected to one outer wall of the sliding sleeve, and a connecting rod is fixedly connected to the other end of the connecting plate.

[0011] Furthermore, a sliding hole is provided on one side of the housing, and the connecting plate slides within the sliding hole.

[0012] Furthermore, a mounting box is fixed to one side of the outer wall of the housing by bolts. The mounting box covers the outside of the sliding hole, and one end of the connecting rod is slidably inserted into one end of the mounting box.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The heat in the exhaust gas is quickly transferred to the heat medium in the heat pipe through heat conduction. Then, the heat on the heat pipe is transferred to the water in the water tank, thereby heating the water in the water tank and realizing the utilization of the waste heat of the exhaust gas.

[0015] 2. The exhaust gas passes through a filter to remove larger particles of impurities, and then passes through a glass fiber absorbent layer to capture tiny particles and some gaseous harmful impurities such as sulfides, nitrogen oxides, and volatile organic compounds, thereby improving the exhaust gas treatment effect.

[0016] 3. By pulling the connecting rod, the connecting plate moves within the sliding hole, which in turn moves the sliding sleeve on the heat pipe. This causes the scraper to scrape the outer wall of the heat pipe, removing dirt and ensuring the heat conductivity of the heat pipe. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A tail gas treatment structure for a reverberatory furnace includes a housing 1, an air inlet pipe 2 welded to the top of the housing 1, an air outlet pipe 3 welded to the bottom of one side of the housing 1, and a filter mechanism provided inside the housing 1.

[0024] Multiple heat pipes 14 are inserted between the two sides of the housing 1. The heat pipes 14 are made of high thermal conductivity materials, such as copper or aluminum alloy. Both ends of the heat pipes 14 are threaded with sealing caps.

[0025] A water storage tank 8 is fixed to one side of the outer wall of the box 1 by bolts. One end of the heat conduction pipe 14 passes through the inside of the water storage tank 8 and then exits from one side of the water storage tank 8.

[0026] The heat pipe 14 inside the water storage tank 8 has a U-shaped structure that fits into the inner wall of the water storage tank 8. The heat in the exhaust gas is quickly transferred to the medium water in the heat pipe 14 through heat conduction. Then, the heat of the medium water in the heat pipe 14 is transferred to the water in the water storage tank 8. The water in the water storage tank 8 absorbs heat and its temperature rises.

[0027] A water inlet pipe 9 is welded to the top of the water storage tank 8, and a water outlet pipe 10 is welded to the bottom of the water storage tank 8. Both the water inlet pipe 9 and the water outlet pipe 10 are equipped with valves 11. When the valve 11 of the water outlet pipe 10 is opened, the water in the tank 1 flows out.

[0028] The filtration mechanism includes a filter screen 6 and a glass fiber adsorption cotton layer 7. The filter screen 6 is a metal woven mesh or a high-density nylon mesh with a pore size of about 0.1-0.5mm. The main function of the filter screen 6 is to intercept larger particulate impurities in the exhaust gas, such as dust, metal shavings, and unburned solid particles, to prevent these large particulate impurities from entering the subsequent glass fiber adsorption cotton layer 7, thus avoiding rapid clogging of the cotton layer and extending its service life. The glass fiber adsorption cotton layer 7 captures tiny particles with a particle size of 0.01-0.1mm and some gaseous harmful impurities, such as sulfides, nitrogen oxides, and volatile organic compounds, in the exhaust gas.

[0029] A first mounting bracket 4 and a second mounting bracket 5 are slidably inserted into one side of the housing 1. The filter screen 6 and the glass fiber absorbent cotton layer 7 are respectively set in the first mounting bracket 4 and the second mounting bracket 5. A handle is fixed to one side of the first mounting bracket 4 and the second mounting bracket 5 by bolts. By periodically pulling the handle, the first mounting bracket 4 and the second mounting bracket 5 can be pulled out of the housing 1, which facilitates the cleaning and replacement of the filter screen 6 and the glass fiber absorbent cotton layer 7. For example, the condition of the filter screen 6 and the glass fiber absorbent cotton layer 7 can be checked once a week, and they can be cleaned and replaced as needed.

[0030] An observation window 13 is provided on one side of the water storage tank 8, through which the operator can view the water level in real time. A digital display bimetallic thermometer 12 is sealed and inserted into the top of the water storage tank 8. The model of the digital display bimetallic thermometer 12 is WSSX-411, and the digital display bimetallic thermometer 12 displays the water temperature in real time.

[0031] A sliding sleeve 15 is slidably fitted onto the heat pipe 14. A scraper is integrally formed inside the sliding sleeve 15. A connecting plate 16 is welded to one outer wall of the sliding sleeve 15, and a connecting rod 17 is welded to the other end of the connecting plate 16. A sliding hole is provided on one side of the housing 1. The connecting plate 16 slides in the sliding hole. Pulling the connecting rod 17 moves the connecting plate 16 in the sliding hole, thereby moving the sliding sleeve 15 on the heat pipe 14. This causes the scraper to scrape the outer wall of the heat pipe 14, thereby removing the dirt on the heat pipe 14. The side wall of the housing 1 is periodically removed to perform a deeper cleaning of the heat pipe 14.

[0032] A mounting box 18 is fixed to one side of the outer wall of the housing 1 by bolts. The mounting box 18 covers the outside of the sliding hole. One end of the connecting rod 17 is slidably inserted into one end of the mounting box 18, which facilitates the protection of the sliding hole.

[0033] The working principle of this embodiment is as follows: In use, firstly, the external water supply pipe is connected to the water inlet pipe 9, the valve 11 of the water inlet pipe 9 is opened, and the water is injected into the water storage tank 8 through the pump body. The water level is monitored in real time through the observation window 13 to ensure that the U-shaped part of the heat conduction pipe 14 is completely submerged in water. Then, the exhaust gas enters the box 1 from the air inlet pipe 2. Next, the exhaust gas passes through the filter screen 6 to remove larger particles of impurities in the exhaust gas, and then passes through the glass fiber absorbent cotton layer 7 to capture tiny particles (particle size 0.01-0.1mm) in the exhaust gas.

[0034] Then, the exhaust gas comes into contact with multiple heat pipes 14, and the heat in the exhaust gas is quickly transferred to the medium water in the heat pipes 14 through heat conduction. Then, the heat of the medium water in the heat pipes 14 is transferred to the water in the water storage tank 8. The water in the water storage tank 8 absorbs heat and its temperature rises. At the same time, the digital display bimetallic thermometer 12 displays the water temperature in real time, which can be used as hot water for production or domestic use, thereby realizing the recovery and reuse of exhaust gas heat and reducing the temperature of the exhaust gas.

[0035] Then, the exhaust gas is discharged from the exhaust pipe 3 for further processing;

[0036] Finally, open valve 11 on water outlet pipe 10, and water flows out of tank 1;

[0037] During cleaning, pulling the connecting rod 17 causes the connecting plate 16 to move within the sliding hole, thereby causing the sliding sleeve 15 to move on the heat conduction pipe 14, which in turn causes the scraper to scrape the outer wall of the heat conduction pipe 14, thus removing the dirt from the heat conduction pipe 14. The scraped dirt falls to the bottom of the housing 1.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
