[0025] Through the above technical solution, in the gas heating device provided by the present disclosure, a heating box 2 and a heat exchange box 3 are arranged in the moving box 1. The heating box 2 has a first inlet 511 for allowing a heat exchange medium to enter and a heater 22 for heating the heat exchange medium. The heat exchange box 3 has a second inlet 531 for allowing a replacement gas to enter. At the same time, the heat exchange box 3 also has a first outlet 521 and a second outlet 541 for the heat exchange medium and the replacement gas to exit. In this way, when the gas heating device provided by the present disclosure is in use, the staff can complete the heating of the heat exchange medium at any suitable location. First, control the communication pipe 4 to cut off the communication between the heating chamber 21 and the heat exchange chamber 31, then introduce the heat exchange medium into the heating chamber 21 through the first inlet 511, and heat it through the heater 22.

[0026] It should be noted here that under the condition of being able to store a certain amount of heat and being able to conduct heat exchange with the gas, the heat exchange medium provided by the present disclosure can be any suitable liquid substance, such as water, oil, special liquid, etc. The present disclosure does not make specific limitations on this.

[0027] In the gas heating device provided by the present disclosure, the heat exchange medium and the replacement gas can enter the heating chamber 21 and the heat exchange chamber 31 in any suitable manner. The present disclosure does not make specific limitations on this. As an exemplary embodiment, refer to Figure 1As shown in the figure, the heating box 2 may be provided with a first inlet pipe 51. One end of the first inlet pipe 51 communicates with the heating chamber 21, and the other end extends out of the moving box 1 and forms a first inlet 511. The heat exchange box 3 may be provided with a second inlet pipe 53, a second outlet pipe 54, and a first outlet pipe 52. One end of the second inlet pipe 53 communicates with the heat exchange chamber 31, and the other end extends out of the moving box 1 and forms a second inlet 531. One ends of the first outlet pipe 52 and the second outlet pipe 54 respectively communicate with the heat exchange chamber 31, and one ends of the first outlet pipe 52 and the second outlet pipe 54 extend out of the moving box 1 and respectively form a first outlet 521 and a second outlet 541. In this way, the staff can introduce the heat exchange medium and the replacement gas into the heating box 2 and the heat exchange box 3 from outside the moving box 1. Specifically, the heat exchange medium is introduced into the heating chamber 21 through the first inlet pipe 51, and after being heated by the heater 22, it enters the heat exchange chamber 31 through the connecting pipe 4. The replacement gas is introduced into the heat exchange chamber 31 through the second inlet pipe 53, and after fully exchanging heat with the heat exchange medium, it is discharged from the heat exchange box 3 through the second outlet pipe 54 and at the same time discharged outside the moving box 1. The heat exchange medium is discharged from the heat exchange box 3 through the first outlet pipe 52 and at the same time discharged from the moving box 1, realizing the heating of the replacement gas.

[0028] In the gas heating device provided by the present disclosure, the first inlet pipe 51 and the second inlet pipe 53 may be respectively arranged on the heating box 2 and the heat exchange box 3 in any suitable manner, and the present disclosure does not make specific restrictions on this.

In the present disclosure, the heat exchange medium is usually a liquid. After entering the heating box 2 through the first inlet pipe 51, it falls to the bottom of the heating box 2 under the action of its own gravity. In this way, the arrangement of the first inlet pipe 51 at the top of the heating box 2 can avoid the situation where the heat exchange medium flows out of the heating box 2 without setting a switching valve 522. The replacement gas is usually gaseous. After entering the heat exchange box 3 through the second inlet pipe 53, it rises to the top of the heat exchange box 3. In this way, the arrangement of the second inlet pipe 53 at the bottom of the heat exchange box 3 can enable the gas to fully contact the heat exchange medium flowing into the bottom of the heat exchange box 3 through the connecting pipe 4, realizing the full heating of the replacement gas.
