Technical Field

[0001] This utility model relates to the field of organic flue gas waste heat recovery technology, specifically to an organic flue gas waste heat recovery device for industrial kilns. Background Technology

[0002] Industrial kilns are equipment constructed of refractory materials for calcining materials or firing products. They are classified into ceramic kilns and cement kilns. An existing patent, CN210922233U, describes a waste heat recovery device for industrial kiln flue gas. It includes a first channel with one end open in the kiln's flue, sequentially connecting to a second, third, fourth, fifth, and sixth channel. A natural air channel is connected to the kiln via a heat pipe air preheater. A water pipe is installed in the second channel. Filter devices are installed in the third, fifth, sixth, seventh, and latent heat channels. A waste heat flow port is located at the top of the fourth channel, connected to a heat collection station via the latent heat channel. This invention provides a waste heat recovery device for industrial kiln flue gas. Through multi-layer filtration, it improves the removal of harmful substances in the flue gas, reducing the amount of harmful substances emitted into the air, thus benefiting environmental protection. Furthermore, this invention performs multiple recovery treatments on the waste heat of the flue gas, improving its utilization rate.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: although they can filter through the filtration structure, the lack of an effective structure for recovering grease from organic flue gas makes it easy for excessive grease to enter the recovery device and cause pipe blockage, thus limiting their effectiveness. Therefore, we propose an industrial kiln organic flue gas waste heat recovery device to solve the above-mentioned problems. Utility Model Content
