Abstract

The invention provides a high pressure array-typed automatic cleaning device, comprising a supporting frame, a driving unit, a fan-covered cleaning pipe bundle and a nozzle. The technical key point is that the supporting frame is fixedly provided with a guideway which is provided with a bracket-typed cleaning platform with a travelling wheel; the cleaning platform is provided with a horizontal driving unit which can move along the guideway; the horizontal driving unit sequentially comprises a motor, a reducer, a synchronous gear-shaped belt, a synchronous gear-shaped belt pulley, an output shaft and a travelling wheel; the lower side of the cleaning platform is provided with a cleaning bracket; the lower side of the cleaning bracket is connected with at least a fan-covered cleaning pipe bundle where the nozzles are uniformly distributed by a hoisting frame. The high pressure array-typed automatic cleaning device adopts two rows of pipe bundles, firstly cleans the upper half plane with the upper pipe bundle, then cleans the lower half plane with the lower pipe bundle, namely by a half pipe bundle horizontal flat pushing type. Compared with other cleaning types, the high pressure array-typed automatic cleaning device saves the cleaning time of the reciprocating stroke along the vertical direction and greatly improves the cleaning efficiency.

Description

technical field [0001] The invention relates to the technical field of cleaning of electric power, environmental protection, energy, coal mines and other equipment, in particular to a high-pressure beam array automatic cleaning device for an A-shaped air cooler in a direct air cooling system (ACC) of a power plant. Background technique [0002] At present, the high-pressure water automatic cleaning of the A-shaped air cooler in the direct air cooling system (ACC) of the power plant adopts the square array scanning method at home and abroad. [0003] The characteristics of the square array scanning cleaning are: the cleaning bracket and nozzles are set on the A-type tower, the cleaning system realizes automatic operation in the horizontal direction (parallel to the steam distribution pipe), and 2 to 3 groups of nozzles are set in the vertical direction to realize the cleaning of the cooling fins. Vertical flushing of the tube. Each group of nozzles can run automatically in t...
