Obviously, the described embodiments are only part of the embodiments of the present utility model, not all implementations. example. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

The purpose of this utility model is to provide a gas heating device to solve the above-mentioned problems existing in the prior art and to extend the service life of the heater.

In order to make the above-mentioned purposes, features and advantages of the present utility model more obvious and easy to understand, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.

The utility model provides a gas heating device. As shown in Figure 1, the gas heating device includes a shell 1, a heating component 2, a heat-conducting medium, two closed disks 3, a plurality of vent pipes 4, a controller and a temperature sensor. The shell 1 is a heat-resistant steel shell, the closing disk 3 is a heat-resistant steel disk, the vent pipe 4 is a heat-resistant steel vent pipe, the shell 1 is open at both ends, and the plurality of vent pipes 4 are open at both ends. They are respectively connected with two closed disks 3, and the two closed disks 3 are sealed and connected with the openings at both ends of the housing 1 to form a heating cavity. The two closed disks 3 can be opposite to the housing 1 around the axis of the housing 1. Rotate, a plurality of vent tubes 4 are arranged in a circular array around the axis of the housing 1, and the vent tubes 4 are arranged at an included angle with the axis of the housing 1. The included angle is specifically 3 to 30°, preferably 10 to 20°. More preferably, it is 20°; the heating component 2 is fixedly installed on the inner wall of the heating cavity through a fixing piece and is not in contact with the plurality of vent pipes 4. The heat-conducting medium is a liquid medium, which fills the heating cavity, and the temperature sensor is fixedly set up through a fixed connecting piece. In the heating chamber, the temperature sensor and the heating component 2 are electrically connected to the controller through wires.

It is worth noting that the specific structure of the rotary sealing connection between the disc and the opening of the housing 1 is an existing technology. Specifically, the rotary shaft seal in the patent with authorization announcement number CN101046254B or other structures that meet the requirements can be used.

Specifically, the heating component 2 is a plurality of heating elements arranged in a circular array around the axis of the housing 1; the heating elements are heating rods; and the heat transfer medium is heat transfer oil or other liquids.

During the specific implementation process, the opening at one end of the housing 1 is connected to the transportation pipeline of the gas to be heated, and the gas enters the ventilation tube 4. Since the ventilation tube 4 forms an angle with the axis of the housing 1, the gas can drive the closed disc 3 and The ventilation tube 4 rotates, so that the ventilation tube 4 can stir the heat-conducting medium and achieve rapid and even transfer of heat; and because the heating component 2 does not contact the ventilation tube 4, the heating medium is used for heat transfer, thereby avoiding the risk of heating. The component 2 is locally overheated, causing the vent pipe 4 to be burned and deformed, thereby extending the service life of the heater.
