PL438074A1 - Method and device for cooling the exhaust gas of a combustion engine of a tractor of suspended monorail tractor - Google Patents

Abstract

In the method of cooling the exhaust gases of the internal combustion engine of the suspended monorail drive in the tractor in the shell-and-tube heat exchanger, the exhaust gas stream from the engine exhaust manifold (2) is divided through a sieve plate into a series of parallel exhaust gas streams directed to thin-walled tubes with spiral exhaust guides embedded in them (4e), causing the formation of all flue gas streams and introducing them into a helical - swirling motion that flows around the inner cylindrical active surface of thin-walled tubes, while the rotational movement of the helical flue gas guides (4e) is blocked. The exhaust gas cooling device of the internal combustion engine drive in the tractor of suspended monorails in the thin-walled tubes of the shell-and-tube exchanger (4) has at least one spiral exhaust gas guide (4e), and the rotational movement of the spiral exhaust gas guide (4e) is blocked. In turn, two mounting arms are attached to the outer surface of the shell-and-tube heat exchanger (4), and their ends are fixed to the internal structure of the suspended monorail tractor. In another variation, the exhaust gas cooling method (SP) of the exhaust gas stream from the exhaust gas collector (2) is divided through a screen plate into a series of parallel exhaust gas streams directed to thin-walled tubes, introducing the spiral exhaust gas guides (4e) embedded in them into rotation, and in the device in the thin-walled In the tubes of the shell-and-tube heat exchanger (4), at least one helical flue gas guide (4e) is rotated.
