Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of steam pipeline structures, and in particular relates to a steam pipeline purge terminal structure. Background Art
[0002] The heating steam pipeline transports superheated steam. After the steam pipeline is installed and welded, it must undergo a water pressure test in accordance with the pipeline acceptance and operation specifications. After the water pressure test is completed, the entire pipeline must be steam-purged to ensure that there are no foreign objects in the steam pipeline. The existing conventional technology is to directly connect the external pipeline at the end of the buried steam pipeline to an open area, and install an end valve to ensure that the pressure is released after reaching the specified pressure. The release time meets the specified requirements. Generally, the pressure is released back and forth three or more times to ensure that the pipeline is clean.
[0003] The existing technology is more suitable for remote and open areas, and is not suitable for the purging of urban municipal steam pipelines. First, at the beginning of steam purging, a large amount of sewage and debris is discharged from the pipeline, which has an impact on the existing environment. Second, during the purging of the steam pipeline, a lot of noise is generated, which seriously affects the lives of surrounding residents. Third, in the later stage of steam purging, the pipeline is basically clean and mainly consists of a gas-water mixture or steam. A large amount of white atomized steam is suspected to be on fire, causing unnecessary trouble to the surrounding community and relevant management departments. Fourth, the safety risk of the structure is high and uncontrollable, mainly reflected in the risk of the operator of the end release valve. If encountering special sections such as urban main roads and overpasses, there will be a certain risk of visual obstruction to the safe driving of vehicles. Utility Model Content
[0004] In response to the above-mentioned technical problems, the utility model provides a steam pipe purge terminal structure to solve the environmental impact problems such as noise and visual obstruction at the existing steam pipe purge terminal. The steam pipe purge terminal structure can effectively reduce the impact of steam emissions on the surrounding environment.
[0005] The utility model discloses a steam pipe purge terminal structure, comprising a container, a steam pipe, a purge terminal control valve, a steam blow pipe muffler, a spray pipe and an air outlet pipe; the steam pipe extends from the outside of the container to the inside of the container, and the end of the steam pipe located inside the container is connected to the steam blow pipe muffler, the purge terminal control valve is arranged on the pipe section of the steam pipe located outside the container, one end of the air outlet pipe is located at the bottom of the inner cavity of the container, and the other end of the air outlet pipe extends out of the container, the spray pipe is located at the top of the inner cavity of the container, the spray pipe is provided with a plurality of spray ports, the bottom of the container is provided with a plurality of drain ports, and the drain ports are provided with a liquid seal structure.
[0006] Furthermore, the steam blowpipe silencer has a steam outlet, and the steam outlet is arranged obliquely upward.
[0007] Furthermore, a plurality of air inlets are provided on the pipe section of the air outlet pipe located inside the container.
[0008] Furthermore, the pipe section of the air outlet pipe located outside the container is provided with an exhaust port, and an atomizing sprayer is provided on the periphery of the exhaust port.
[0009] This steam pipe purge terminal structure installs a steam blowpipe silencer at the rear end of the purge terminal control valve of the steam pipe. The outside of the steam blowpipe silencer is semi-enclosed by a container, and a spray pipe is installed inside the container. This effectively reduces noise and quickly cools down the air, and the white smoke is greatly reduced. The device completely isolates the purge terminal control valve and the end of the steam pipe through the container, ensuring the safety of personnel operation. Secondly, the internal installation of a steam blowpipe silencer and the protection of a container can greatly reduce the impact of noise on the surrounding environment. At the same time, the exhaust pipe is located at the bottom of the container, which can ensure that the steam is discharged from the bottom. The internally installed spray pipe can effectively cool down the air, ensure that the overflow steam is quickly liquefied, reduce the visual impact, and will not cause damage or pollution to the surrounding structures of the urban building complex.
