DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 A kiln smoke exhaust pipe with filtering function comprises a pipe body 1, a top cover 2 is arranged on the top of the pipe body 1, and a filtering and heating device 3 is arranged inside the pipe body 1;

[0023] The filtering and heating device 3 includes a first filter plate 301, a connecting rod 302, a second filter plate 303, a heat absorbing pipe 304, a hot water tank 305, a cold water tank 306, a water pump 307, a support rod 308, a first spring 309 and a limit rod 310. The first filter plate 301 is movably connected inside the pipeline body 1, the connecting rod 302 is fixedly installed at the bottom of the first filter plate 301, the second filter plate 303 is slidably connected to the outer surface of the connecting rod 302, the heat absorbing pipe 304 is fixedly installed inside the pipeline body 1, the hot water tank 305 is fixedly installed on the right side of the pipeline body 1, the cold water tank 306 is fixedly installed on the left side of the pipeline body 1, the water pump 307 is fixedly installed on the top of the cold water tank 306, the support rod 308 is fixedly installed on the bottom of the top cover 2, the first spring 309 is fixedly installed inside the pipeline body 1, and the limit rod 310 is fixedly installed on the outer surface of the first spring 309.

[0024] Specifically, Figure 2 As shown, after the device has been used for a period of time, the handrail is pulled to move in the relative direction, thereby driving the limit rod 310 to move along the outer surface of the auxiliary rod and compressing the first spring 309, and then the top cover 2 and the support rod 308 are taken out from the slot of the pipeline body 1, and then the first filter plate 301 and the second filter plate 303 are taken out from the slide groove of the pipeline body 1 through the pull ring, and then the limit block is pressed to squeeze the second spring, so that the second filter plate 303 is taken out from the connecting rod 302, so as to clean the first filter plate 301 and the second filter plate 303, and repeat the above operation after cleaning to reinstall and continue to use.

[0025] Specifically, Figure 2 As shown, the heat absorption tube 304 is a stainless steel heat exchange tube. The stainless steel heat exchange tube is a heat exchange equipment component widely used in various industrial fields. Its main function is to transfer heat between the heat source and the cold source. The stainless steel heat exchange tube is mainly made of stainless steel materials such as 316L. These materials have good corrosion resistance and high temperature resistance, so as to absorb the waste heat of the flue gas in the pipe body 1 and transfer the heat to the internal liquid.

[0026] Specifically, Figure 2 As shown, the material of the first filter plate 301 is activated carbon material, which is widely used in flue gas filtration due to its strong adsorption capacity and can effectively remove harmful substances in the flue gas. The material of the second filter plate 303 is diacetate fiber bundle, which is often used to make filter media and can effectively capture particulate matter in the flue gas, thereby achieving a filtering effect.

[0027] When implementing, follow these steps:

[0028] 1) First press the limit block and the second spring, and then pass the connecting rod 302 through the second filter plate 303, so as to connect the first filter plate 301 and the second filter plate 303;

[0029] 2) Then put the connected first filter plate 301 and the second filter plate 303 into the chute in the pipeline body 1;

[0030] 3) Insert the top cover 2 into the slot of the pipe body 1 through the support rod 308 and fix it through the first spring 309 and the limit rod 310;

[0031] 4) Finally, the water pump 307 is turned on to filter the flue gas and recover and use the residual heat in the flue gas.

[0032] To sum up, when the kiln smoke exhaust pipe with filtering function is in use, the smoke inside the pipe body 1 will rise from the bottom to the top, turn on the water pump 307, pump out the cold water in the cold water tank 306 and send it to the heat absorption pipe 304, when the smoke passes through the heat absorption pipe 304, the residual heat in the smoke will be absorbed by the heat absorption pipe 304, and then transferred to the liquid inside the pipe, and the heated liquid will finally be sent to the hot water tank 305 for temporary storage, and when the smoke continues to rise to the second filter plate 303, the impurities and dust in the smoke will be initially filtered, and when it reaches the first filter plate 301, it will be filtered for the second time, and finally the filtered smoke will be discharged, so as to achieve the purpose of filtering the smoke and recycling the heat in the smoke.
