Detailed Description
The invention is further described with reference to the following figures and examples.
The utility model provides an engine exhaust waste heat recovery heat exchanger, as shown in figure 1, including setting up outer tube 4 in the tail gas pipe 5 outside, set up spiral fin 6 between tail gas pipe 5 and the outer tube 4, set up air inlet joint 9 in one side of outer tube 4, the opposite side sets up the joint 3 of giving vent to anger, sets up pipe cap 2 at the both ends of outer tube 4. Flanges 1 are arranged at two ends of the tail gas pipe 5, the tail gas pipe 5 and the outer sleeve 4 are bent, or the tail gas pipe 5 and the outer sleeve 4 are linear.
The working principle is as follows:
the preheating and recycling heat exchanger for the tail gas of the engine is characterized in that when the engine works, the generated high-temperature tail gas (300-400 ℃) is connected with an inlet of a waste heat recycling heat exchanger for the tail gas of the engine through an exhaust port 10 of the tail gas of the engine, 11 high-temperature tail gas of the engine is discharged through a tail gas pipe 5, at the moment, a low-temperature medium to be heated enters an outer sleeve 4 through an air inlet connector 9, the medium is in full contact with the outer wall of the tail gas pipe 5 and a spiral fin 6 to exchange heat, the heated high-temperature medium is conveyed to a required occasion through an air outlet connector 3 to exchange heat energy, and the low-temperature tail gas of the engine is discharged.
As shown in the attached figure 2, the engine tail gas waste heat recovery heat exchanger is connected with an engine tail gas exhaust port through a flange 1 and a pipeline, the flange 1 at the other end of the engine tail gas preheating recovery heat exchanger is connected with a silencer 12, and the silencer exhaust port is directly communicated with the natural environment.
Although the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
