Gas heating device

Abstract

The invention discloses a gas heating device. The gas heating device comprises an insulation shell. A heating chamber is arranged inside the insulation shell. A gas inlet enabling the heating chamber and an external gas inlet pipe to communicate is formed in the bottom of the insulation shell. A gas outlet enabling the heating chamber and an external gas outlet pipe to communicate is formed in the top of the insulation shell. A partition plate is arranged in the middle of the heating chamber in the vertical direction. A plurality of heating pipes which sequentially penetrate through the side walls of the heating chamber and the partition plates in the horizontal direction are arranged on the lateral portion of the insulation shell, and the heating pipes are sequentially arranged in the vertical direction. Wiring terminals which are connected with an external power distribution cabinet are arranged at the outer ends of the heating pipes. According to the gas heating device, internal assemblies are arranged reasonably, working noise is low, and online replacement or maintenance of the heating pipes can be achieved.

Description

technical field [0001] The invention relates to the technical field of gas heating equipment, in particular to a gas heating device. Background technique [0002] At present, in the existing metal smelting or machining fields, electric heaters are a kind of gas heating equipment commonly used, and with the continuous improvement of people's product process requirements, the performance of gas heating devices is also increasingly concerned by people . [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a gas heating device in the prior art. [0004] Such as figure 1 As shown, the heating pipe 32 of the existing gas heating device is usually inserted into the equipment body 31 from the top of the body 31 in the vertical direction and penetrates the partition 33. The partition 33 is usually arranged horizontally and is limited by the structure and space at the same time. In the prior art, the partition 33 mostly adopts a thin plate, and the...

Problems solved by technology

[0004] like figure 1 As shown, the heating pipe 32 of the existing gas heating device is usually inserted into the equipment body 31 from the top of the body 31 in the vertical direction and penetrates the partition 33. The partition 33 is usually arranged horizontally and is limited by the structure and space at the same time. In the prior art, the partition 33 mostly adopts a thin plate, and the partition 33 adopts a half width and multi-layer arrangement, and the airflow resistance is large, and the partition 33 has high-frequency vibration under the impact of the large air flow, and the noise on site is obvious; in addition, due to the horizontal arrangement of the partition 33 has no effective support, resulting in large deformation of the partition 33 under the action of high-speed airflow and high temperature during the operation of the equipment. Therefore, after the electric heating tube 32 is pulled out during use, it cannot be inserted back into its original position, resulting in the replacement of the electric heating tube 32 every time Or maintenance requires downtime, unable to achieve online replacement or maintenance
