This invention relates to the field of waste heat utilization technology, and more particularly to an energy-saving chemical waste heat utilization device, comprising a chemical furnace, a tail gas processor, and a heat exchanger. An exhaust pipe is installed on the outer wall of the chemical furnace, and a buffer tank is connected to the outer wall of the exhaust pipe via a flange. The invention utilizes a cleaning mechanism where a motor-driven exhaust fan rotates, transporting tail gas to the tail gas processor. The motor drives a mounting bracket to rotate, which in turn drives a scraper to rotate, scraping off dust adhering to the inner wall of the exhaust pipe. The dust enters the buffer tank with the tail gas flow. Furthermore, after the heat from the tail gas is transferred to the second cylinder, the gas inside the cylinder expands and pushes the second piston to compress the second spring, thereby further tightening the scraper against the inner wall of the exhaust pipe, improving the scraping effect. This converts the heat from the tail gas into a pre-tightening force between the scraper and the exhaust pipe, ensuring the utilization rate of tail gas waste heat while improving the cleaning effect.
