DETAILED DESCRIPTION

[0020] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0021] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. The present utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-6 As shown, the utility model proposes an exhaust gas waste heat recovery ventilation device, including a heat exchanger 1, the heat exchanger 1 is a plate heat exchanger 1, which increases the heat exchange area between the exhaust gas and the fresh air, the upper end of the heat exchanger 1 is connected with an exhaust gas inlet pipe 2 and an air outlet pipe 3, and the lower end is connected with an air inlet pipe 4 and an exhaust gas outlet pipe 5; the exhaust gas inlet pipe 2, the air outlet pipe 3, the air inlet pipe 4 and the exhaust gas outlet pipe 5 are all embedded with a connecting plate 6, the connecting plate 6 is plugged with a clamping plate 7, and a filter 14 is arranged in the clamping plate 7, and a fan 13 is installed at one end of the exhaust gas inlet pipe 2 and the air inlet pipe 4 to send the exhaust gas and the fresh air into the heat exchanger 1 at the same time;
