A high-temperature-resistant, high-pressure, self-adaptive special pipeline cleaning equipment and its cleaning method

Abstract

The invention discloses a high-temperature-resistant, high-pressure, self-adaptive special pipeline cleaning equipment and its use method, which includes a pipeline cleaning device, a traction device, a universal connector and a centralized control management platform, wherein the traction device, The universal connector and the pipeline cleaning device are connected sequentially. The pipeline cleaning device includes a first fixed frame, a positive discharge electrode, a negative discharge electrode and a high-power pulse power supply. The positive discharge electrode, a negative discharge motor and a high-power The pulse power supply is fixedly arranged on the first fixed frame, the positive discharge electrode and the negative discharge electrode are set oppositely, and the high-power pulse power supply is connected to the power supply of the centralized control management platform through a special cable. The invention has no pollution in operation, good adaptability to pipelines and wide working range.

Description

technical field [0001] The invention relates to a high-temperature-resistant, high-pressure and self-adaptive special pipeline cleaning equipment. Background technique [0002] After long-term operation of underground pipelines, oil and gas pipelines, and liquid transportation pipelines, impurities in the transport medium tend to adhere to the inner wall of the pipeline, causing pipeline blockage and affecting the transmission capacity. There are harsh working conditions such as high temperature, high pressure and strong corrosion in oil and gas pipelines and chemical plant transportation pipelines. Strong acid and strong alkali are routinely used for corrosive cleaning of pipelines, but there are secondary pollution problems, especially when it comes to residential pipelines. huge. When manual cleaning is used, construction cannot be carried out for small-diameter pipes. When cleaning with wireless robots, due to the electromagnetic shielding effect of the pipeline itself...

Problems solved by technology

[0002] After long-term operation of underground pipelines, oil and gas pipelines, and liquid transportation pipelines, impurities in the transport medium tend to adhere to the inner wall of the pipeline, causing pipeline blockage and affecting the transmission capacity.

There are harsh working conditions such as high temperature, high pressure and strong corrosion in oil and gas pipelines and chemical plant transportation pipelines. Strong acid and strong alkali are routinely used for corrosive cleaning of pipelines, but there are secondary pollution problems, especially when it comes to residential pipelines. huge

When manual cleaning is used, construction cannot be carried out for small-diameter pipes

When cleaning with wireless robots, due to the electromagnetic shielding effect of the pipeline itself, it is often difficult to accurately control the position of the robot under complex pipeline layouts
