Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device for recycling waste heat of high-temperature waste gas. Background Art

[0002] In current industrial production activities, the emission of high-temperature exhaust gas has become a major challenge to energy consumption and environmental pollution. To address this issue, many companies and research institutions are committed to developing efficient exhaust gas waste heat recovery technology to reduce energy waste and promote sustainable environmental development. Traditional exhaust gas waste heat recovery devices mostly use water heating to recover waste heat in the exhaust gas. This process usually involves a heat exchange system, which transfers the heat carried by the exhaust gas to the circulating water body, thereby realizing the reuse of heat energy, such as generating hot water for production processes or domestic heating. However, this traditional method has significant technical limitations.

[0003] First, since the heat exchange efficiency is limited by the heat transfer rate, when the exhaust gas emission is large and needs to be processed quickly, the water in the existing heat exchange device is often difficult to efficiently absorb the heat in the exhaust gas in a short period of time, resulting in some waste heat not being effectively recovered. Secondly, the water flow inside the heat exchanger is unevenly distributed. The water flow close to the heat source area is heated more violently, while the water flow far away from the heat source is not heated enough. This uneven heating will reduce the overall heat exchange efficiency, thereby affecting the heat transfer and greatly reducing the waste heat recovery effect. No effective solution has been proposed to the problems in the relevant technology. Therefore, it is necessary to propose an exhaust gas treatment device for the reuse of high-temperature exhaust gas waste heat to solve the above-mentioned problems. Utility Model Content

[0004] In view of the problems in the related technology, the utility model proposes an exhaust gas treatment device for recycling the waste heat of high-temperature exhaust gas to overcome the above-mentioned technical problems existing in the existing related technology.

[0008] Furthermore, in order to monitor the temperature of water in the heat absorbing tube, a temperature sensor is fixedly installed on one side of the inner wall of the heat absorbing tube.

[0009] Furthermore, in order to allow the exhaust gas to enter the second intake pipe after passing through the driven bevel gear, a vent hole is provided inside the driven bevel gear.

[0010] Furthermore, in order to achieve stable support for the air intake pipe 2 in the heat absorption tube, the two ends of the air intake pipe 2 are fixedly connected to a support frame, one end of the support frame is fixedly connected to a positioning rod, and the two ends of the positioning rod are fixedly connected to the inner wall of the air intake pipe 1.

[0011] Furthermore, in order to facilitate closing and opening of the drain pipe, a closing cover is slidably installed at one end of the drain pipe.

[0012] Furthermore, in order to realize the control of various electrical components in the device, a multi-control switch is fixedly installed on the surface of one side of the air intake pipe.

Then, the sealing cover and the stirring rod are driven by the rotating motor to rotate in the heat absorption pipe to stir the water inside, thereby increasing the fluidity of the heat absorption water, accelerating the heat transfer speed of the heat absorption pipe, and improving the efficiency of waste heat recovery of the exhaust gas.
