[0002] At present, the tail gas discharged from the boiler contains a lot of heat and has a high temperature. If the tail gas is directly discharged into the atmosphere, it will not only waste a lot of heat energy, but also pollute the atmosphere and cause the ambient temperature to rise. for recycling
The current tail gas waste heat recovery and utilization device has a complex structure, high manufacturing cost, and low recovery and utilization rate

Abstract
The invention discloses a boiler tail gas residual heat recycling device. The boiler tail gas residual heat recycling device comprises a boiler, a first draught fan, a second draught fan, a first pipeline, a second pipeline, a tail gas outlet pipe and a tail gas chimney, wherein a first sleeve sleeves the tail gas chimney; a second sleeve sleeves the tail gas outlet pipe; the tail gas outlet pipe is communicated with the tail gas chimney; the first sleeve is communicated with the second sleeve; the second sleeve is provided with an air outlet; the air outlet of the second sleeve is connected with the first draught fan; the first draught fan is connected with the second draught fan by the first pipeline; the second draught fan is connected with the boiler by the second pipeline; the boiler is communicated with the tail gas outlet pipe; the tail gas chimney connected with the tail gas outlet pipe is provided with a tail gas outlet. According to the boiler tail gas residual heat recycling device, tail gas in the tail gas outlet pipe and the tail gas chimney can be subjected to heat exchange with air so that the temperature of the air entering the boiler is raised, the temperature of fuel gas in the boiler is improved and the tail gas residual heat is recycled. The boiler tail gas residual heat recycling device has a simple structure and lower cost.
Description
technical field [0001] The invention relates to the technical field of waste heat recovery and utilization, in particular to a boiler tail gas waste heat recovery and utilization device. Background technique [0002] At present, the tail gas discharged from the boiler contains a lot of heat and has a high temperature. If the tail gas is directly discharged into the atmosphere, it will not only waste a lot of heat energy, but also pollute the atmosphere and cause the ambient temperature to rise. for recycling. The current tail gas waste heat recovery and utilization device has a complex structure, high manufacturing cost and low recovery utilization rate. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a boiler tail gas waste heat recovery and utilization device that can effectively recover tail gas waste heat, has a simple structure and low cost. [0004] In order to achieve th...
