Description

Technical Field

[0001] The utility model relates to the technical field of tail gas pipelines, and more specifically to a device for preventing condensation in a drying kiln tail gas pipeline. Background Art

[0002] A drying kiln is a device used to dry materials, usually used in the material drying process in industrial production. The drying kiln heats the air or other media, sends the wet materials into the kiln, and evaporates or distills the water in the materials through hot air or radiation heating, thereby achieving the purpose of drying the materials;

[0003] The tail gas pipeline is a waste gas pipeline containing water vapor, flue gas and other gases discharged from the drying kiln. During the operation of the drying kiln, the hot tail gas generated by fuel combustion or other means will be discharged into the tail gas pipeline, and after treatment and discharge into the atmosphere. The device to prevent condensation in the tail gas pipeline of the drying kiln is a device installed on the tail gas pipeline. Through components such as thermal insulation, anti-condensation coating, and anti-condensation film, condensation is prevented from occurring in the tail gas pipeline during the cooling process, thereby avoiding moisture, dripping, corrosion and other problems, and ensuring the normal operation and production efficiency of the drying kiln.

[0004] Existing devices for preventing condensation in the tail gas pipe of a drying kiln usually only use a single heating method to heat the surface of the tail gas pipe to reduce the generation of condensation. However, in actual use, the tail gas generated by the drying kiln when drying the material still contains a large amount of moisture, which often adheres to the inner wall of the pipe, thereby forming a certain amount of moisture accumulation. The existing anti-condensation device lacks an effective drainage mechanism, which brings many inconveniences to actual use.

[0005] Moreover, in the process of drying materials, the exhaust gas not only contains moisture, but also often contains a certain amount of impurities. These impurities often stick to the inner wall of the pipe due to the mixing of water. This will increase the thermal resistance of the pipe, thereby increasing the energy consumption required for heating, which will cause great trouble to actual use.

[0006] In view of this, we propose a device to prevent condensation in the exhaust gas pipeline of the drying kiln. Utility Model Content

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the utility model has the following advantages: when in use, the tail pipe can be heated in all directions by multiple electric heating tubes, thereby significantly increasing the temperature of the tail pipe, which can effectively avoid condensation caused by excessive temperature difference between the tail gas and the tail pipe. Secondly, during use, the gear motor can be used to drive the rotating gear ring to rotate at a constant speed, so that the scraper rod on its inner wall can discharge the water accumulated in the tail pipe and drain the water into the collection bucket.
