Embodiment Construction
[0024] The present invention will be described in more detail below in conjunction with the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0025] Such as Figure 1-4 As shown, the special air pulse cleaning device of the present invention includes a left cylinder body 1 and a right cylinder body 2 arranged horizontally; The liquid injection hole 4 is located on the inner wall of the right cylinder on the left side of the liquid injection hole 4, and is fixed with three inclined guide plates 5 along the radial direction, and the angle between each guide plate 5 and the axis of the cylinder is 45±5°; Between the left cylinder 1 and the right cylinder 2, a left pressure plate 6, a middle plate 7, and a right pressure plate 8 of a hollow ring structure are sequentially arranged, and the flashing plate 9 is installed on the middle plate 7 through the pressure ring 10 (the flashing plate 9 and pressure ring 10 are fixed on the middle pla...

The invention discloses a cleaning method for large-diameter complex pipelines. A special air pulse cleaning device is adopted. When cleaning, first pressurize, and the high-pressure gas makes the atomized cleaning agent flow forward along the pipeline and also flow along the radial direction. As the spiral rotates, the moving cleaning agent droplets impact the inner wall of the pipeline. Under the synergistic effect of impact and dissolution, the dirt can be quickly and thoroughly dissolved, achieving the purpose of thoroughly cleaning the pipeline, and solving the problem of pipeline localization during conventional chemical cleaning. Especially the upper inner wall of the large-diameter pipeline) cannot touch the cleaning agent, and the technical problem that the pipeline cannot be thoroughly cleaned, even if there are elbows and tees on the pipeline, it can be effectively cleaned; due to the invention The cleaning method adopts a special air pulse cleaning device, which makes the whole cleaning system have the characteristics of safety, high efficiency and energy saving. It has obvious advantages in construction efficiency, construction effect and waste liquid treatment, etc., and has great market application prospects and promotion value. .
Description
technical field [0001] The invention relates to chemical cleaning pipeline technology, in particular to a method for cleaning large-diameter complex pipelines with elbows, tees and variable-diameter pipelines used in petrochemical and other systems. Background technique [0002] At present, the cleaning methods generally used for domestic petrochemical system pipelines and equipment are chemical cleaning, PIG physical cleaning and high-pressure steam purging. 1. Chemical cleaning is divided into two types: immersion cleaning and circular cleaning, and circular cleaning is generally the main method. During cyclic chemical cleaning, the centrifugal pump at the cleaning tank pressurizes the cleaning liquid, and the chemical cleaning liquid establishes a cycle in the pipeline system to achieve the purpose of cleaning the pipeline system. This cleaning method has a better cleaning effect on small-diameter pipes. The cleaning liquid is easy to fill the pipe, and the flow rate is ...
