Abstract
The invention relates to a rotary vane cavitation jet type pipeline cleaner which comprises a central shaft and rotary vanes, wherein the rotary vanes are uniformly distributed on the outer surface of the central shaft, and the rotary vanes are spiral in structure. The washer is placed in the pipe and is pushed to move in the pipe by the pressurized water flow. When water flows through the gap between the blades and the pipe wall of the cleaner, the speed is increased, the pressure is reduced, cavitation can occur when the water flow is lower than the water vapor pressure, and acting force generated by cavitation acts on dirt, so that the purpose of cleaning the pipeline is achieved.
Description
Technical Field
The invention relates to the technical field of pipeline cleaning, in particular to a rotary vane cavitation jet type pipeline cleaner and a cleaning method thereof.
Background
In the process industry, pipes for transporting media are very common. In the use process, the factors such as impurities, ionic substances, corrosiveness and the like in the fluid tend to cause scaling, sediment, microorganism breeding and the like on the wall surface of the pipeline, so that the flow section of the pipeline is reduced or even blocked, and normal production is influenced. For example, in the petroleum industry, with continuous development and popularization, oil pipelines exhibit more and more fouling problems, and one of the important factors affecting the development of oil fields is the problem of pipeline fouling. Therefore, a cleaning technology which is convenient to develop and efficient is imperative. This problem is also present in other industries, and most pipes are located underground, and fouling can cause pipe blockage, which is not negligible in terms of cleaning and safety.
Conventionally, industrial pipeline cleaning mainly includes a physical method, a chemical method, and a mixing method. Chemical cleaning utilizes chemical agents to chemically react with the dirt, which dissolves in the chemical agents and then is discharged through a cleaning liquid. The chemical agents used are mainly acids, bases, organic solvents and surfactants depending on the type of soil. Physical cleaning methods do not involve chemical reactions, utilize physical forces, such as external energy, etc., to break up the dirt, which is then expelled with the cleaning liquid, whereas cavitation water jets, i.e., physical methods, as studied herein account for about 75% of all industrial cleaning.
In an objective aspect, the present cleaning methods have shortcomings. Chemical cleaning methods are limited because chemicals are corrosive, chemical residues are harmful to the pipeline, and the selection of chemical cleaning solutions is inconvenient. The physical cleaning method has the defects that the operation pressure is about 100-280MPa, the used equipment is expensive, the cleaning distance is short, the sectional cleaning is needed, and the like, and the cleaning is inconvenient.
The cavitation jet cleaning is a new cleaning method, mainly uses cavitation acting force, and the cavitation jet cleaning belongs to a physical method as can be known from the description, but overcomes the defects of the traditional physical method, and has a great application prospect. The cavitation cleaning method utilizes a rotary vane type cleaner to induce cavitation bubbles, and then the cavitation bubbles are continuously developed and collapsed to generate strong jet flow to act on the surface of dirt, so that the dirt is broken up, and the cleaning purpose is achieved. Has important research significance for the research of the high-efficiency cleaning method.

placing the cleaner into the pipeline, and pushing the cleaner to move by adopting pressurized water flow; taking out after moving for a certain distance, and cleaning the pipeline at the next section;
and (3) introducing water flow into the cleaned pipeline, and flushing broken dirt out of the pipeline.
Preferably, a gap exists between the maximum diameter of the rotary blade and the pipe wall of the pipe, and the gap is controlled within 5 mm.
Preferably, the pressure of the pressure water flow is controlled between 0.5MPa and 2 MPa.
Preferably, the movement distance of the cleaner is more than 1000m under the pushing action of water flow.
The beneficial effects of the invention are as follows:
