Unpowered online cleaning device

Abstract

The invention discloses an unpowered online cleaning device, and relates to the technical field of cleaning devices. The online cleaning device comprises a ball serving device and a ball collecting device, and the ball serving device is a laminar flow type jet device; the first input end of the ball serving device is used for being connected with a water inlet pipe, and a connecting port of a jetflow outlet end of the ball serving device is used for being directly connected with a connecting port of a water inlet end of a to-be-cleaned device, and the shape and the size of the connecting portat the outlet end are matched with that of the connecting port of the water inlet end; and the input end of the ball collecting device is connected with the water outlet end of the to-be-cleaned device, and the ball water output end of the ball collecting device is connected with the negative pressure second input end of the ball serving device. According to the online cleaning device, an existing rubber ball pump or cleaning water pump is omitted, the special ball serving device is installed at the water inlet end connecting port of the to-be-cleaned device, cleaning rubber balls are ejectedinto the to-be-cleaned device through a jet flow mode, the principle of jet flow and the pressure of a system are utilized so that on-line circulation cleaning can be realized without the aid of an additional power source, the energy-saving effect is obvious, meanwhile, the rubber balls are relatively uniformly input to the to-be-cleaned device, and then the cleaning efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cleaning devices, in particular to a non-powered online cleaning device. Background technique [0002] During the operation of the condenser, with the splash evaporation of the cooling tower, the concentration ratio increases, and the content of calcium and magnesium ions that are easy to scale in the cooling circulating water is getting higher and higher. When the cooling water flows through the heat exchange tubes of the condenser, hardness scale is formed. Oxygen dissolved in cooling water can also cause metal corrosion, and the corrosion product rust forms rust scale. The dust in the air enters the circulating water system along with the cooling tower and the slime produced by microbial metabolism forms dirt. In the cooling circulating water, the place with the slowest flow rate is the heat exchange tube of the condenser. These hardness scales, rust scales and dirt form composite scales in the heat ...

AI Technical Summary

Problems solved by technology

In the cooling circulating water, the place with the slowest flow rate is the heat exchange tube of the condenser. These hardness scales, rust scales and dirt form composite scales in the heat exchange tube of the condenser, which leads to the decline of the heat exchange effect of the condenser, and it will be blocked when the scaling is serious. tubes, making the heat transfer effect useless

[0003] For a long time, traditional cleaning methods such as mechanical methods (scraping, brushing), high-pressure water, chemical cleaning (pickling), etc. have caused many problems when cleaning equipment: need to stop cleaning; mechanical cleaning damages the protective film of the condenser water side pipe , can not completely remove scale and other deposits; chemical cleaning acid will cause corrosion to the equipment and form loopholes, and the residual acid will cause secondary corrosion or under-scaling corrosion on the material, which will eventually lead to the replacement of equipment. In addition, the cleaning waste is toxic and requires a lot of money wastewater treatment

[0010] 1. High energy consumption in operation: At present, the rubber ball type online cleaning device uses a rubber ball pump or a cleaning water pump to transport water, rubber balls or a mixture of rubber balls and water to the entrance of the cleaned device to clean the cleaned device

[0011] 2. Low cleaning efficiency: the rubber ball is in a turbulent state at the water inlet of the device to be cleaned, and the water inlet pipe of the device to be cleaned is smaller than the water inlet port of the object to be cleaned, so that the cleaning rubber ball can only scrub the middle of the device to be cleaned and the water inlet pipe. Part of the objects that are connected, but for the cleaning objects whose water inlet end is larger than the water inlet pipe, online cleaning cannot be realized, so the cleaning effect is poor
