Description

Technical Field

[0001] The utility model belongs to the technical field of waste heat recovery, and particularly relates to a device for recovering and utilizing waste heat from high-temperature industrial waste gas. Background Technique

[0002] The waste gas generated in the industrial production process, such as incineration waste gas and smelting waste gas, often contains a large amount of heat. If this heat can be effectively recovered and utilized, it can not only improve the energy utilization efficiency, reduce energy waste, but also reduce production costs and environmental pollution at the same time. However, the flue gas often contains solid impurities such as dust. When recovering waste heat, these impurities will cover the surface of the equipment, making it difficult for the heat in the waste gas to be transferred to the heat recovery medium.

[0003] After retrieval, there is a waste heat recovery device with the publication number of CN219368481U in the prior art. This device exchanges heat between the waste gas entering the heat exchange tube and the cold water in the box. The waste gas after heat exchange enters the inside of the second air pipe from the second connecting pipe and is transported away from the device along the second air pipe. At the same time, a stirring paddle in the box is controlled by a motor to stir the water in the box. After using for a period of time, the bottom cover is opened, and the rotating handle and the rotating rod are controlled to drive the scraper inside the heat exchange tube to rotate, so that the scraper scrapes the impurities in the inner cavity of the heat exchange tube. However, the rotating rod and the scraper in the device are exposed to high-temperature gas for a long time, which not only easily causes damage to the device, but also easily causes impurities to adhere to the rotating rod and the scraper, affecting the normal operation of the device.

[0004] After retrieval, there is a waste heat recovery device for treating organic waste gas with the publication number of CN219283354U in the prior art. The combustion chamber of this device conducts high-temperature treatment on the organic waste gas. Subsequently, the generated high-temperature clean gas will enter the dust filtration bin area through the exhaust square pipe for filtration and adsorption treatment. Then, the high-temperature gas enters the serpentine pipe installed inside the water tank. At the same time, water is connected to the water inlet pipe from the bottom up to fill the inner cavity of the water tank, and heat exchange is carried out with the high-temperature gas in the serpentine pipe. The tail pipe connected to the serpentine pipe can secondary pass the waste heat into the gas-gas plate heat exchanger to exchange heat with the organic waste gas entering from the intake square pipe. The dust filtration bin area in this device is also exposed to high-temperature gas for a long time, which not only easily damages the device, but also loses some heat in the flue gas. Summary of the Invention

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a device for recovering and utilizing waste heat from high-temperature industrial waste gas. The utility model cleans the heat exchange tube through a cleaning mechanism to prevent the heat exchange efficiency from decreasing due to dust covering the heat exchange tube.
