Structure for cleaning cavitation device by utilizing hyperventilation cavitating jet

Abstract

The invention provides a structure for cleaning a cavitation device by utilizing hyperventilation cavitating jet. The cavitation device comprises a cavitation device wall surface, wherein a cavitation device chamber is formed in the inner part of the cavitation device wall surface, the cavitation device chamber comprises a cavitation device inner part contraction section, a cavitation device inner part advection section and a cavitation device inner part diffusion section which are sequentially communicated, the end part of the cavitation device inner part diffusion section is positioned at one end of the cavitation device wall surface, a cavitation device spray nozzle inlet is formed in the other end of the cavitation device wall surface, the cavitation device spray nozzle inlet is connected with a pump, a ventilation inlet is formed in the cavitation device wall surface between the cavitation device spray nozzle inlet and the cavitation device inner part contraction section, and the ventilation inlet is communicated with the cavitation device spray nozzle inlet and the cavitation device inner part contraction section. According to the cavitation device provided by the invention, the number of gas nucleus in water can be effectively increased, the collapsing and perishing number of cavitation bubbles can be increased, high pressure which is obtained through collapsing and perishing of the cavitation bubbles is used for cleaning, the pumping pressure needed for cleaning can be effectively reduced, and the energy consumption can be reduced.

Description

technical field [0001] The invention relates to a cleaning device. Background technique [0002] The world's cleaning technology is developing rapidly, and new cleaning methods and cleaning technologies are constantly emerging. It is particularly worth noting that: from the statistics of cleaning technology patents in the world, chemical cleaning only accounts for 1 / 4, while most of them are physical cleaning methods. In addition, as countries around the world pay more and more attention to environmental protection. It also limits the development of chemical cleaning. For example: the United States no longer uses acidic cleaning agents. In the cleaning of heat exchange equipment in petrochemical companies in the United States, except for 10% that do not need to be cleaned, 80% of them use high-pressure water jet cleaning. The use of chemical cleaning only 5%. In recent years, many units in China are still using acid-based chemical cleaning. Chemical cleaning discharges ...

Problems solved by technology

The traditional cleaning method of oilfield tubing is to put the tubing into a large pool of acid and lye and boil it. This method does not clean thoroughly, and the scrap rate of the tubing is high. At the same time, it consumes a lot of energy and pollutes the environment.
