Waste heat recovery device for briquette coal production

The waste heat recovery device for briquette coal production comprises a recovery box, a machining groove is formed in the recovery box, one side of the recovery box is fixedly connected with an air inlet pipe, and the top of the air inlet pipe is fixedly connected with a flue gas inlet. According to the principle that hot air ascends and cold air descends, the top smoke inlet is connected with an exhaust pipe for briquette coal production, smoke is fed into the recycling box through the air inlet pipe, smoke separation is conducted through the air distribution cylinder connected with the air inlet pipe, hot air is conveyed through the first conveying pipe and finally exhausted through the hot air outlet, and hot air collection is conducted; the working efficiency of the waste heat recovery device for briquette coal production is improved, and the problems that during briquette coal production, in the recovery process of an existing waste heat recovery device, due to design reasons, a large amount of heat is
