[0030] like Figures 1 to 6 As shown in the figure, this embodiment provides a flue gas cooling device to prevent clogging. The flue gas cooling device includes a device body 1 and an L-shaped tube 2 installed inside the device body 1. A support ring 21 is installed on the outer surface of the L-shaped tube 2. The support ring 21 is located inside the device body 1 and its bottom is fixedly connected to the inner side of the device body 1, which can provide support force for the L-shaped tube 2. One end of the L-shaped tube 2 extends to the outer side of the device body 1 and is fixedly connected to it. A filter element 3 is provided inside the device body 1 and on the outer side of the device body 1. An auxiliary element 4 is installed on the top of the device body 1.

[0031] The filter element 3 includes a fixed sleeve 31 fixed inside the L-shaped tube 2. A filter frame 32 is movably connected inside the fixed sleeve 31. A coarse filter hole 33 is opened on one side of the filter frame 32, and a fine filter hole 34 is opened on the other side of the filter frame 32. The coarse filter hole 33 and the fine filter hole 34 are arranged at equal intervals. A filter element plate 35 is movably connected inside the filter frame 32. The coarse filter hole 33 can filter out larger particulate matter, such as large pieces of coal and large slag, which can reduce the impact of these particulate matter when entering the subsequent filter element plate 35 and play a buffering role. The filter element plate 35 can filter particulate matter and other pollutants in the flue gas, including smaller particulate matter, such as dust and ash. The fine filter hole 34 can further filter out tiny particulate matter in the flue gas, as well as smaller particulate matter screened by the filter element plate 35 and the coarse filter hole 33. In order to ensure its normal filtration effect and extend its service life, the three-layer filtration structure can filter particulate matter and other pollutants in the flue gas, thereby preventing the problem of pipeline blockage.
[0032] T-shaped blocks 36 are fixedly connected to the top and bottom of the filter frame 32. A T-shaped groove 37 is provided on the inner side of the fixing sleeve 31. The T-shaped blocks 36 are located inside the T-shaped groove 37 and are movably connected to it, which can maintain the stability of the filter frame 32 when it is disassembled.
[0033] The top and bottom of the filter element plate 35 are fixedly connected with trapezoidal strips 38. The inner side of the filter frame 32 is provided with a trapezoidal groove 39. The trapezoidal strips 38 are located inside the trapezoidal groove 39 and are movably connected to it, which can maintain the stability of the filter element plate 35 when it is disassembled.
[0034] A connecting plate 351 is fixedly connected to one end of the filter element plate 35. The connecting plate 351 is located inside the filter frame 32 and is movably connected to it. A handle 353 is fixedly connected to one end of the connecting plate 351 and located outside the filter frame 32. Bolts 352 are movably sleeved on both sides of the connecting plate 351. One end of the bolt 352 passes through the connecting plate 351 and extends into the interior of the filter frame 32 and is threadedly connected to it. In this way, the filter element plate 35 and the filter frame 32 can be fixed. When disassembling, simply reverse the bolt 352. The handle 353 facilitates the disassembly of the filter element plate 35 or the filter frame 32.
[0035] The auxiliary component 4 includes a smoking chamber 41 fixed to the top of the main body 1 of the device. An air pump 42 is installed on the top of the smoking chamber 41. The bottom of the smoking chamber 41 is fixedly connected to the L-shaped tube 2, and the two are internally connected. The output end of the air pump 42 is connected to the smoking chamber 41, which can facilitate the entry of smoke into the interior of the L-shaped tube 2 and play a traction role for the smoke.
[0036] A smoke exhaust pipe 43 is fixedly connected to one side of the smoke chamber 41. A solenoid valve 44 is installed on the top of the smoke exhaust pipe 43. A suction fan 45 is installed inside the smoke chamber 41. The solenoid valve 44 can control whether the inside of the smoke exhaust pipe 43 is in a closed state. The suction fan 45 helps to exhaust the cooled smoke.
[0037] The cooling component 5 includes a water tank 501 located on one side of the main body 1. A serpentine tube 51 is installed on the outer surface of the L-shaped tube 2. A water pump 52 is fixedly connected to the top of the serpentine tube 51. One end of the water pump 52 passes through the main body 1 and extends into the interior of the water tank 501. A water pump 53 is installed inside the water pump 52. The water pump 53 is located on one side of the main body 1. The surface of the water pump 52 is fixedly connected to the main body 1, which can conveniently pump the cooling water inside the water tank 501 into the interior of the serpentine tube 51 to cool the flue gas inside the L-shaped tube 2. The serpentine tube 51 is located on the top of the support ring 21.
[0038] A drain pipe 54 is fixedly connected to the bottom of the serpentine tube 51. One end of the drain pipe 54 passes through the main body 1 of the device and extends into the interior of the water tank 501, which facilitates the drainage of cooling water inside the serpentine tube 51 into the interior of the water tank 501. Figure 2 As shown, the water tank 501 has a two-layer structure. The water pumping pipe 52 is located inside the upper layer of the water tank 501, and the drain pipe 54 discharges the cooling water into the lower layer of the water tank 501, which can avoid the waste of cooling water and at the same time can perform circulating heat exchange for the flue gas. The top of the water tank 501 is provided with an inlet for easy filling of cooling water, and an outlet for easy discharge of cooling water is installed on one side.
[0039] The cooling component 5 also includes a water storage ring 55 installed on the outside of the smoke chamber 41. One end of the water storage ring 55 is equipped with a water inlet pipe 56, and the other end of the water storage ring 55 is equipped with a water outlet pipe 57. The other end of the water outlet pipe 57 is located on one side of the water tank 501, and the two are connected. In this way, the flue gas can be cooled again to improve the flue gas cooling effect.
[0040] In use, flue gas is injected through one side of the L-shaped pipe 2, i.e., the outer end of the main body 1 of the device, and the suction pump 42 is started at the same time, so that it assists the entry of flue gas through the smoke chamber 41 and the L-shaped pipe 2. During this process, the flue gas will pass through the filter element 3. The coarse filter hole 33 can filter out larger particles, such as large pieces of coal and large slag, which can reduce the impact of these particles when they enter the subsequent filter plate 35 and play a buffering role. The filter element of the filter plate 35 can filter particulate matter and other pollutants in the flue gas, including smaller particles, such as dust and ash. The fine filter hole 34 can further filter out tiny particles in the flue gas, as well as smaller particles screened by the filter plate 35 and the coarse filter hole 33. In order to ensure its normal filtration effect and extend its service life, the three-layer filter structure can filter particulate matter and other pollutants in the flue gas, thereby preventing the problem of pipe blockage.
[0041] When replacing or cleaning the filter element 3, simply pull the handle 353 to make it slide out along the inside of the fixing sleeve 31 through the filter element plate 35. Then remove the bolt 352 to disassemble the filter element plate 35 and the filter frame 32, thereby facilitating the replacement or cleaning of the filter element 3.
[0042] At the same time, by starting the water pump 53, the cooling water inside the water tank 501 is pumped into the serpentine tube 51 through the water pumping pipe 52. As the cooling water continues to enter, it will flow slowly along the inside of the serpentine tube 51 and carry away the heat of the flue gas inside the L-shaped tube 2. The cooling water finally flows to the lower layer of the water tank 501 through the drain pipe 54, thus achieving the purpose of cooling the flue gas.
[0043] Next, cooling water can be injected into the water inlet pipe 56 to cool the smoke inside the smoke chamber 41, thus improving the cooling effect.
[0044] Finally, once the flue gas has cooled down, the exhaust pipe 43 can be connected to the inside of the smoke chamber 41 by activating the solenoid valve 44, and the flue gas can be discharged by activating the suction fan 45 to complete the operation.

Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
