Description

Technical Field

[0001] The invention relates to the technical field of pipeline cleaning, and in particular to a pure physical cleaning technology for pipelines without stopping transmission. Background Art

[0002] Most of the existing pipeline cleaning technologies are chemical cleaning technology, PIG cleaning technology and high-pressure water jet cleaning. The disadvantages of chemical cleaning technology are large amount of waste liquid, high difficulty in disposal, complex process flow, harsh conversion conditions, difficult control, difficulty in cleaning insoluble pipe scale, and need to be heated for secondary replacement reaction. Long-distance and large-diameter pipelines cannot be cleaned, the amount of liquid medicine is huge, and online cleaning without stopping production cannot be achieved. The disadvantages of PIG cleaning technology are that when the pipeline is deformed or the scale in the pipe is irregular, it cannot be cleaned, the hard scale cleaning effect is not good, and secondary blockage is easy to form. It requires fire and earthwork, and online cleaning without stopping production cannot be achieved. The disadvantages of high-pressure water jet cleaning are that it requires fire, earthwork, disassembly and assembly, cannot clean over long distances, and is difficult to clean. Large diameter pipes require cleaning spray gun brackets and weight-bearing cleaning, which increases the pressure on the equipment, and online cleaning cannot be achieved without stopping production.

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and propose a pipeline continuous online pure physical cleaning technology. The technical solution adopted by the present invention is:

[0004] The pipeline is continuously transported online pure physical cleaning technology, including the following steps: air preparation, water supply preparation, cleaning work and recycling;

[0005] Air preparation: compress the air and store the compressed air for intermittent charging;

[0006] Water supply preparation: supply water to the cleaning pipe to fill the pipe with water;

[0007] Cleaning work: Compressed air is rushed into the pipeline, and the compressed air is exploded to form impact force, thereby performing cleaning work;

[0008] Recycling: The wastewater is recycled by tanker trucks, so that the clean debris is also recycled.

[0009] As an improvement, the air preparation includes an air supply port, a screw air compressor, a compressed air storage tank and a CNC high-frequency pulse controller.

[0010] As an improvement, the water supply work includes a water supply port and a water pump.

[0011] As an improvement, the cleaning work includes cleaning the process inlet, the official website to be cleaned and the cleaning process outlet.

[0019] Figure 1 It is the cleaning workflow diagram of the present invention. DETAILED DESCRIPTION

[0020] In order to make the content of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention, wherein the same components are represented by the same reference numerals.

[0021] The following steps: air preparation, water supply preparation, cleaning work and recycling;

[0022] Air preparation: compress the air and store the compressed air for intermittent charging;

[0023] Water supply preparation: supply water to the cleaning pipe to fill the pipe with water;

[0024] Cleaning work: Compressed air is rushed into the pipeline, and the compressed air is exploded to form impact force, thereby performing cleaning work;

[0025] Recycling: Recycling wastewater via tanker trucks, thereby also recycling clean debris;

[0026] Air preparation includes air supply port, screw air compressor, compressed air storage tank and CNC high-frequency pulse controller;

[0027] Water supply work includes water supply ports and water pumps;

[0028] The cleaning work includes cleaning the process inlet, the official website to be cleaned, and the cleaning process outlet;

[0029] Recycling includes sewage recycling tank trucks;

[0030] Without using any chemical agents, it has no corrosion to the pipe network, has no requirements for water quality, will not form new pollution sources, and is green, safe and environmentally friendly;

[0031] It is not blocked and has strong practicability. It can be applied to various complex, variable-diameter, deformed and other series-connected pipe networks, and can achieve non-stop production;

[0032] It is efficient, fast, time-saving and labor-saving, and can be carried out without excavation and disassembly of the pipe network structure;

[0033] The cleaning quality inspection is convenient. The cleaning effect can be inspected by observing the flow rate at the inlet and outlet of the pipe network and comparing the pressure of the pipe network before and after cleaning;

[0034] The cleaning effect is remarkable, and the cleaning rate reaches more than 95%. The recovery of the conveying effect of the pipe network is obvious, and the pipe diameter recovery rate reaches more than 90%.

[0035] During the use process, first do the preparatory work. Connect the air supply port to the screw air compressor and the water supply port to the water pump. The water pump transports water to the cleaning process inlet, so as to fill the inside of the pipeline to be cleaned with water and keep the water inside the pipeline in a full state. The screw air compressor compresses the air and transports the compressed air to the compressed air storage tank for storage. Then, the high-pressure gas is controlled to be filled into the cleaning process input through the numerical control high-frequency pulse controller. The filling of the compressed gas forms an intermittent injection through the numerical control high-frequency pulsation controller. After the high-pressure air enters the pipeline to be cleaned, it will quickly expand to form an air explosion effect. The impact force generated by the air explosion is used to clean the official website to be cleaned, so that the sundries on the wall of the official website to be cleaned are washed down, forming a cleaning effect, and the sundries will be washed away by the water flow, so that the sundries flow out from the cleaning process outlet, and the sewage recycling tank truck collects the sewage carrying the sundries.

[0036] The above is only a preferred embodiment of the present invention patent, and it is not used to limit the present invention patent. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention patent shall be included within the protection scope of the present invention patent.
