The utility model discloses a hot air heat tracing discharging device in a severe cold region, which comprises a discharging device, wherein the discharging device comprises a shell, and the shell comprises a shell outer sleeve 1 and a shell inner sleeve 2. A heating cavity is formed between the shell outer sleeve 1 and the shell inner sleeve 2. The housing shell 1 is provided with a first air inlet for communicating the first hot air duct with the heating chamber. The shell is also provided with a first air outlet 9, and the first air outlet 9 is used for discharging hot air after heat exchange.
Hot air flows through the first hot air pipeline, and the hot air is formed by absorbing waste heat of the waste gas. The hot air has the characteristic of difficult condensation, so the hot air can directly pass through the heating cavity. Therefore, the hot air is directly contacted with the shell outer sleeve 1 and the shell inner sleeve 2 of the discharging device, so that the thermal resistance and the heat loss are reduced, and the heat exchange efficiency is improved. A first air outlet 9 is further arranged on the shell casing 1, and the first air outlet 9 is used for discharging hot air after heat exchange. In addition, compared with the prior art that the heat tracing pipe is arranged in the heating cavity, the heating mode of directly utilizing the heating cavity to heat greatly simplifies the structure, and simultaneously avoids the problems of difficult maintenance and high failure rate of the heat tracing pipe.

Furthermore, the utility model also arranges a guide plate 7 on the outer wall of the inner housing 2 of the housing and opposite to the first air inlet, referring to fig. 7, the guide plate 7 has two arc-shaped guide surfaces 10 symmetrically arranged, and the two arc-shaped guide surfaces 10 guide the hot air to the left and right sides. In this way, the hot air is divided into two streams which follow the two semicircular tracks of the heating chamber and then join and exit through the first air outlet 9.
It should be noted that, because the guide plate 7 is arranged right opposite to the first air inlet, hot air collides with the guide plate 7 after entering, so as to avoid the hot air from scouring the inner sleeve 2 of the shell, thereby prolonging the service life of the inner sleeve 2 of the shell.
The first air inlet is in communication with the first hot air duct via an air inlet duct 8. An air inlet pipe 8 is arranged at the first air inlet, and the air inlet pipe 8 is connected with a first hot air pipeline through a first flange 15. And a second flange connected with the air inlet pipe 8 is arranged on the shell casing 1. The air inlet pipe 8 is connected to the housing shell 1 via a second flange.
For the first air outlet 9, the utility model arranges the first air outlet 9 on the housing case 1, and the first air outlet 9 is used for communicating the heating cavity and the outside atmosphere. I.e. the hot air passing through the heat exchange with the heating chamber will be discharged directly to the outside atmosphere through the first air outlet 9. Therefore, the hot air after heat exchange is beneficial to heating the surrounding environment of the feeding device by waste heat, so that the feeding device is in a working environment with higher temperature to prevent the feeding device from freezing.
