Carbon steel pipeline plugging device for chemical cleaning

Technical Field

The utility model belongs to the technical field of industrial cleaning, and particularly relates to a carbon steel pipeline plugging device for chemical cleaning.

Background

In the industrial production field, like the electricity generation field etc, the medium in the pipeline is used for thermal transmission, and system operation is after certain cycle, can produce the dirt in the heat exchanger, in the pipeline and in the valve usually, and the dirt in the heat exchanger can lead to heat exchange efficiency to descend, and the dirt in the pipeline can lead to the pipeline internal diameter to reduce and then lead to the medium flow to reduce, and the dirt in the valve can lead to the valve to open smoothly usually or close, leads to the decline to medium pipeline on-off control ability or even inefficacy. Therefore, it is often necessary in the aforementioned field to periodically clean the heat exchanger equipment, the media lines and the valves. The chemical cleaning is a cleaning operation method of injecting chemical agents into a container for soaking and spraying cleaning. The metal container cleaning method has the advantages that the cleaning effect on various dirt can be achieved by selecting the proper cleaning agent and adopting the proper cleaning process, the overlooking effect of the cleaning operation on the metal container can be relieved by controlling the type selection of the cleaning agent and the parameters of the cleaning process, and the chemical cleaning is one of the main modes of the existing cleaning operation.
