Cleaning treatment device for independent walking pipeline

Abstract

The invention provides a cleaning treatment device for an independent walking pipeline. The cleaning treatment device is used for cleaning the inner wall of the pipeline and comprises a first fixing plate, a second fixing plate, a propelling part, a cleaning part and a power part; the propelling part is mounted on the first fixing plate and is provided with at least three propelling mechanisms which are distributed on the same circumference, and each propelling mechanism is composed of a guide unit, a drive unit and a transmission unit; a cleaning unit is a spiral cleaning part and is cylindrical, and a thread is arranged on the outer surface of the cleaning unit; the cleaning unit can axially move along the pipeline while rotating, and therefore friction and cutting of dirt on the inner wall of the pipeline can be achieved, and the effect of cleaning the inner wall of the pipeline is achieved; and the cleaning treatment device for the independent walking pipeline is used for carrying out pipeline cleaning work, the cleaning effect is better, and the cost of pipeline cleaning can be reduced.

Description

technical field [0001] The invention relates to a pipeline cleaning treatment device, in particular to a self-propelled pipeline cleaning treatment device. Background technique [0002] The condenser is an essential equipment in the Rankine thermal cycle of the power plant. This type of equipment realizes the power generation cycle by condensing the exhaust steam of the steam turbine into water by vacuumizing the exhaust. In the condenser, the efficiency of heat exchange is very important. The thermal resistance of the cooling water pipe of the condenser, that is, the cleanliness of the pipe wall, is an important factor affecting the heat exchange efficiency. If scaling or residual dirt occurs in the cooling water pipe, it will cause a decrease in heat exchange efficiency, and the efficiency of the turbogenerator set will also decrease. [0003] According to the survey, the water entering the condenser used in general power plants is sea water, which contains many impuritie...

AI Technical Summary

Problems solved by technology

Generally, there are more than 10,000 pipes in the condensers put into use in power plants, so the cleaning workload is very heavy, and the labor cost of cleaning is very high

At the same time, the cooling water pipe is long, the pipe diameter is between 10-20mm, and there are many bends. The traditional cleaning system (such as rubber ball cleaning, chemical cleaning) is not ideal for removing the dirt on the inner wall of the pipe.

In addition, in the process of using the traditional cleaning system, improper operation may cause damage to the pipe wall
