Description

Technical Field

[0001] The utility model relates to the technical field of waste heat recovery, in particular to a waste heat recovery device. Background Art

[0002] Methacryloyloxypropylmethyldimethoxysilane will generate waste gas during its production and processing, and there will be a lot of heat in the waste gas.

[0003] For example, a high-temperature exhaust gas heat recovery device with patent number CN214666224U includes a main body, an air intake bin located on one side of the main body, a heat recovery mechanism located in the middle of the main body, and a treatment bin located in the main body on the side away from the air intake bin. The air intake bin includes an air inlet located in the middle of the side of the air intake bin away from the heat recovery mechanism. When in use, the high-temperature exhaust gas is transported to the inside of the air intake bin, and the high-temperature exhaust gas is transported to the inside of the treatment bin through the ventilation pipe. The ventilation pipe is set to an "S" shape structure to increase the contact surface between the ventilation pipe and tap water. The block inside the vent pipe slows down the circulation speed of the high-temperature exhaust gas, so as to achieve better heat recovery effect on the high-temperature exhaust gas. The temperature of the tap water inside the heat recovery mechanism is simply sensed by the temperature sensor. However, the position of the air inlet of the recovery device in the above document is fixed. When the waste heat generated during the production and processing of methacryloxypropylmethyldimethoxysilane is recovered, it is not convenient to adjust the angle of the air inlet pipe of the device according to the angle of the exhaust pipe. At the same time, when the exhaust gas is passed into the interior of the device, part of the exhaust gas may be discharged from the air inlet pipe, thereby reducing the waste heat recovery effect of the device.
