Waste heat recycling device for oil refining and chemical engineering

The utility model discloses a waste heat recycling device for oil refining and chemical engineering, which relates to the technical field of oil refining and chemical engineering and comprises a recycling box, a water inlet pipe penetrates through one side of the bottom side surface of the recycling box, a smoke inlet pipe penetrates through the other side of the bottom side surface of the recycling box, and three uniformly distributed treatment boxes are arranged on the top surface of the recycling box. A drainage pipe is mounted on the top surface of the recycling box; under the action of the heat exchange mechanism, the contact surface area of hot air and heat exchange water is larger, the spiral design enables the flowing path of the hot air and the heat exchange water to be longer, the heat exchange efficiency is higher, the situation that heat in the hot air is wasted is avoided, the heat exchange efficiency of the device is improved, and the service life of the device is prolonged. And under the action
