DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] Embodiment 1:

[0025] See also Figure 1-3 , the utility model provides a technical solution: a flue structure, including: a sunken annular groove 1, an annular movable cover plate 8, and an exhaust gas heat exchange device;

[0026] An exhaust gas outlet 2 is provided on the lower surface of the annular groove 1, and an exhaust gas discharge pipe 3 is connected to the lower side of the exhaust gas outlet 2. The upper portion of the annular groove 1 is a flue port. The movable cover plate 8 is movably connected to the upper opening of the annular groove 1. The outer edge of the movable cover plate 8 is sealedly connected to the inner wall of the upper opening of the annular groove 1. An exhaust gas inlet pipe 14 is provided on the upper surface of the movable cover plate 8. The exhaust gas heat exchange device includes a plurality of branch pipes 4 and a heat exchange box 5 arranged on the exhaust gas discharge pipe 3. The branch pipes 4 penetrate the heat exchange box 5. A heat exchange fluid inlet pipe 6 and a heat exchange fluid outlet pipe 7 are respectively connected to the opposite side walls of the heat exchange box 5.

[0027] Analysis of the above content: When using, follow Figure 1 In this way, the exhaust gas inlet pipe 14 is connected to the exhaust gas outlet of the brick kiln 16, and the brick kiln 16 is connected and fixed to the movable cover plate 8. When the brick kiln 16 is working, the brick kiln 16 rotates around the arranged brick blanks, so that the brick blanks at the arrival of the brick kiln 16 are fired (the prior art is not described here). When the brick kiln 16 rotates, it drives the movable cover plate 8 to rotate, so that the exhaust gas generated by the brick kiln 16 is input into the annular groove 1 through the exhaust gas inlet pipe 14, and then discharged from the exhaust gas outlet 2 and the exhaust gas exhaust pipe 3. In this way, an exhaust gas exhaust structure with relative circular rotation motion is formed between the movable cover plate 8 and the annular groove 1, which can ensure the normal discharge of the exhaust gas.

[0028] The discharged exhaust gas is high-temperature exhaust gas, which is dispersed through multiple branch pipes 4. A low-temperature heat exchange liquid (such as cold water) flows through the heat exchange box 5. The branch pipe 4 can be made of copper, which has a good thermal conductivity. The high-temperature exhaust gas flowing through the branch pipe 4 heats the low-temperature heat exchange liquid. The heated low-temperature heat exchange liquid is heated to a high-temperature heat exchange liquid, and the high-temperature heat exchange liquid absorbs and utilizes the remaining temperature of the exhaust gas.
