Description

Technical Field

[0001] The utility model relates to the technical field of steam conveying equipment, and more specifically, to a steam conveying device. Background Art

[0002] Boiler steam has a wide range of uses in industrial production. Boiler steam needs to be transported from the boiler to the destination through steam pipes. Steam transportation is the transportation of water vapor in gaseous form. During the transportation process, due to heat loss and other reasons, part of the steam will liquefy and condense into condensed water, blocking the steam transportation pipeline and hindering steam transportation.

[0003] A dehydration device for a steam transmission pipeline disclosed in a utility model patent with Chinese patent number ZL202121680615.5 is retrieved, comprising an outer shell assembly, a drainage core assembly, a steam guide pipe flange assembly, and a base. The outer shell assembly is composed of a steel cylinder and two butt-welding flanges, the two butt-welding flanges are respectively welded and connected to the two ends of the steel cylinder, the butt-welding flange at the lower end of the outer shell assembly is connected to the drainage core assembly, the base is connected to the lower bottom surface of the drainage core assembly, the butt-welding flange at the upper end of the outer shell assembly is connected to the steam guide pipe flange assembly, a steam inlet pipe is installed on the side wall of the steel cylinder of the outer shell assembly, the steam inlet pipe is connected to the inner cavity of the steel cylinder, a drain pipe is installed on the bottom surface of the drainage core assembly, the drain pipe extends from the side of the base, a steam guide pipe is installed on the upper end of the steam guide pipe flange assembly, the steam guide pipe is connected to the inner cavity of the steel cylinder of the outer shell assembly, the structure is simple, the volume is small, and the use is convenient, the condensed water of the steam condensation can be effectively discharged from the steam pipeline, and the drainage device can be sealed to prevent the loss of steam and ensure the normal transportation of steam.

[0004] Since the diameter of the steel cylinder is larger than the diameter of the steam delivery pipe, its heat dissipation area is relatively large. During the circulation of steam inside the steel cylinder, a large amount of heat will be lost, increasing the amount of condensed water generated, resulting in a decrease in the gas pressure inside the steel cylinder. In addition, during the installation process, most of the external steam delivery pipes are fixedly installed, and then there is a certain difference in the front and rear positions of the pipes connecting the steam guide pipe and the steam inlet pipe of the steam delivery device, resulting in the two external pipes that need to be connected not being in the same plane, resulting in the steam guide pipe and the steam inlet pipe not being able to correspond to the positions of the external pipes that need to be connected at the same time, and sometimes there is a difference in the height and lateral distance of the pipe connection ports connected to the steam guide pipe and the steam inlet pipe of the steam delivery device, resulting in the steam guide pipe and the steam inlet pipe being unable to be connected to the external pipes that need to be connected at the same time, thereby increasing the difficulty of its installation and reducing the practicality of its use.
