Condenser cooling water pipe cleaning robot

Abstract

The invention discloses a condenser cooling water pipe cleaning robot. The condenser cooling water pipe cleaning robot comprises a cleaning robot body, a robot transferring device and a mechanical arm; the robot transferring device is arranged on the mechanical arm and used for transferring the cleaning robot body between condenser cooling water pipes; the cleaning robot body comprises a shell, traveling wheels, an advancing motor, balance supporting wheels, a cleaning rotating knife, a cleaning rotating knife rotating shaft and a cleaning motor, wherein the shell is cylindrical, the balance supporting wheels are connected with the shell through a torsion spring; and the radial length of the cleaning rotating knife can be adjusted, and the cleaning rotating knife is in the shape of a torsion blade. According to the condenser cooling water pipe cleaning robot, the internal soft scale of the condenser cooling water pipes can be well removed, the online operation is facilitated, the cleaning efficiency of the device is greatly improved, the operation efficiency of a steam turbine set is greatly improved, all-directional cleaning can be carried out, safety and reliability are achieved,and heat transfer deterioration caused by dirt is avoided.

Description

technical field [0001] The invention relates to the field of condenser cleaning, in particular to a condenser cooling water pipe cleaning robot. Background technique [0002] Fouling is an important reason for the performance degradation of surface condensers in power stations, resulting in a decrease in the operating economy of the unit and an increase in pollution emissions. Condenser fouling is an important controllable loss of the unit. Through online or offline cleaning, the heat transfer performance can be restored, the exhaust pressure of the steam turbine can be reduced, the energy utilization rate of the unit can be improved, and the pollution emission per unit of power generation can be reduced. Therefore, the cleaning of power station condensers, especially on-line cleaning, is an important technology to be overcome urgently in thermal power plants. [0003] Scholars at home and abroad have conducted many studies on the cleaning of condensers. At present, the cle...

AI Technical Summary

Problems solved by technology

However, the high water pressure is not easy to control, and it is easy to deform

In addition, the maintenance cost of the equipment is high, the waste of water resources is quite large, and the cleaning effect for more serious fouling is not good

[0008] The rubber ball cleaning technology currently has many defects. Domestic power stations need regular inspections, and manual judgment is used to determine whether it is necessary to replace the rubber balls. The replacement of rubber balls is cumbersome and labor-intensive.

In addition, the design of unit equipment is unreasonable, the selection of gel balls is wrong and other reasons cause the recovery rate of rubber balls to be low, so the operating cost increases and the cleaning quality decreases

Especially when the thickness of hard slag accumulates in the pipe and the inner diameter is small, using rubber balls to clean it will block the pipe, which will lead to poor heat transfer.
