The working principle of the waste gas incinerator usually uses diesel, heavy oil or natural gas as fuel, and converts the harmful substances in the waste gas into harmless substances such as carbon dioxide and water through combustion. In addition, the waste gas incinerator can also achieve waste heat recovery by adding heat exchange equipment, so as to achieve the purpose of saving energy.
[0003] During the use of the existing waste gas combustion furnace, the flue gas after combustion will be discharged into the atmosphere through the chimney, and there will be residual harmful substances in the discharged flue gas. In order to avoid polluting the atmosphere, it is necessary to filter the discharged flue gas, so as to ensure that the discharged flue gas will not pollute the atmosphere.
[0004] The treatment of flue gas usually uses a filtering device to filter out the harmful substances in the flue gas. After long-term use, the filtering device will be blocked, thus reducing the filtering effect. Therefore, it is necessary to clean and disassemble the filtering device. However, the existing waste gas combustion furnace is not simple enough when cleaning and replacing the filtering device, increasing the working difficulty of the operator and affecting the use of the combustion furnace.
[0005] Therefore, a waste gas combustion furnace is specifically proposed. Content of the Utility Model

Specific embodiments
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0021] Embodiment 1: One end of the combustion furnace main body 18 is welded with the chimney main body 15. A plurality of support sliding rods 20 are welded inside the chimney main body 15. A filter frame 21 is slidably sleeved outside the support sliding rods 20. The upper and lower ends of the filter frame 21 are open. A plurality of limiting chute seats 23 are respectively welded at equal intervals on both sides inside the filter frame 21. A filter screen 22 is movably installed inside the limiting chute seats 23.

A plurality of rotary limiting plates 19 are movably installed on one side of the chimney main body 15. The plurality of rotary limiting plates 19 are respectively used in cooperation with the sealing plate 13.
[0022] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, after the waste gas enters the interior of the combustion furnace chamber 2 and undergoes combustion treatment, the flue gas generated by the combustion of the waste gas will enter the interior of the chimney main body 15. Since a filter frame 21 is movably installed inside the chimney main body 15 and the upper and lower ends of the filter frame 21 are open, therefore, the flue gas entering the interior of the chimney main body 15 will pass through the filter frame 21 and then be discharged into the atmosphere. Since a plurality of filter meshes 22 are movably installed inside the filter frame 21, the harmful substances contained in the discharged flue gas can be filtered in multiple layers through the plurality of filter meshes 22, so as to filter out pollutants with different particle sizes, reduce the pollution after the flue gas is discharged, and when disassembling, cleaning and replacing the filter frame 21, the plurality of rotary limit plates 19 movably installed on one side of the chimney main body 15 can be rotated, so as to cancel the limiting effect of the rotary limit plates 19 on the sealing plate 13. Subsequently, the entire filter frame 21 can be pulled out from the interior of the chimney main body 15 through the two pull rods 14 welded to one side of the sealing plate 13. Since one end of the filter frame 21 is slidably sleeved outside the support slide rod 20, therefore, after the filter frame 21 is pulled out from the interior of the chimney main body 15, it is ensured that the filter frame 21 will not fall. Since both ends of the filter mesh 22 are slidably installed inside the limit chute seat 23, therefore, when replacing the filter mesh 22, only need to pull out the filter mesh 22 from the interior of the filter frame 21, and then insert the two ends of the new filter mesh 22 into the limit chute seat 23 again. Subsequently, push the filter frame 21 back into the interior of the chimney main body 15, and rotate the plurality of rotary limit plates 19 so that the rotary limit plates 19 limit and fix the sealing plate 13. The operation of disassembling, installing and replacing the filter mesh 22 is very simple, reducing the operation difficulty of maintenance personnel, shortening the maintenance time, ensuring that the combustion furnace can be quickly put into use, and improving the use efficiency.
[0023] Embodiment 2: A positioning seat 17 is respectively welded on both sides of the bottom of the combustion furnace main body 18, and a base plate 1 is welded to the bottom of the two positioning seats 17. A combustion furnace chamber 2 is provided inside the combustion furnace main body 18, and the interior of the combustion furnace chamber 2 is communicated with the interior of the chimney main body 15. A fixing block 16 is welded to the bottom of the chimney main body 15, and the bottom end of the fixing block 16 is welded to the top of the base plate 1. One end of the interior of the combustion furnace chamber 2 is fixed with a burner 4, and a blower 6 is installed at one end of the combustion furnace main body 18. One end of the blower 6 is connected with an air delivery pipe 5, and the air delivery pipe 5 extends into the interior of the combustion furnace chamber 2. A heat preservation layer 3 is provided between the inner wall of the combustion furnace main body 18 and the outside of the combustion furnace chamber 2, and a waste gas delivery pipe 9 is welded to the interior of the combustion furnace chamber 2. One end of the waste gas delivery pipe 9 extends out of the interior of the combustion furnace chamber 2 and the combustion furnace main body 18, and one end of the waste gas delivery pipe 9 is hermetically connected with a valve 8, and one end of the valve 8 is hermetically connected with a waste gas pipe 7.
[0024] Specifically, as Figure 1 、 Figure 2 and Figure 3As shown in the figure, since two positioning seats 17 are welded to the bottom of the combustion furnace main body 18, and a base plate 1 is welded to the bottom of the positioning seat 17, the stability of the combustion furnace main body 18 can be ensured through the base plate 1 and the positioning seat 17. The waste gas to be treated can be injected into the interior of the combustion furnace chamber 2 through the waste gas pipe 7, the intake volume of the waste gas can be adjusted through the valve 8, the air can be transported into the interior of the combustion furnace chamber 2 through the air pipe 5 by the blower 6, the waste gas in the combustion furnace chamber 2 can be burned by the burner 4, and the air transported into the combustion furnace chamber 2 through the air pipe 5 can assist in combustion.
[0025] Working principle: During use, the waste gas to be treated can be injected into the interior of the combustion furnace chamber 2 through the waste gas pipe 7, the waste gas in the combustion furnace chamber 2 can be burned by the burner 4, the air can be transported into the interior of the combustion furnace chamber 2 through the air pipe 5 by the blower 6 to assist in combustion. The flue gas generated after the waste gas combustion will enter the interior of the chimney main body 15, and then pass through multiple filter meshes 22 inside the filter frame 21 to filter harmful substances in the flue gas. The flue gas after the filtration treatment will enter the interior of the plate heat exchanger 11. The gas enters the interior of the plate heat exchanger 11 through the air inlet 10, and the air is heated through the heat exchange of the flue gas. The heated air will be discharged through the air outlet 12, thereby recovering the heat of the discharged flue gas. Since this technology belongs to the mature existing technology, it is not specifically described in the text. When disassembling, cleaning, and replacing the filter frame 21, multiple rotating limit plates 19 movably installed on one side of the chimney main body 15 can be rotated, so as to cancel the limiting effect of the rotating limit plates 19 on the sealing plate 13. Subsequently, the entire filter frame 21 can be pulled out from the interior of the chimney main body 15 through two pull rods 14 welded to one side of the sealing plate 13. Since one end of the filter frame 21 is slidably sleeved outside the support slide rod 20, after the filter frame 21 is pulled out from the interior of the chimney main body 15, it is ensured that the filter frame 21 will not fall. Since both ends of the filter mesh 22 are slidably installed inside the limit chute seat 23, when replacing the filter mesh 22, only need to pull out the filter mesh 22 from the interior of the filter frame 21, and then reinsert both ends of the new filter mesh 22 into the limit chute seat 23. Subsequently, push the filter frame 21 back into the interior of the chimney main body 15, and rotate multiple rotating limit plates 19 to make the rotating limit plates 19 limit and fix the sealing plate 13. The operation of disassembling, installing, and replacing the filter mesh 22 is very simple, reducing the operation difficulty of maintenance personnel, shortening the maintenance time, ensuring that the combustion furnace can be quickly put into use, and improving the use efficiency.
