Problems solved by technology

The cleaning solution usually uses 5% hydrochloric acid solution, and a certain amount of corrosion inhibitor is added. During the preparation of the cleaning solution and the subsequent pickling process, the experimenters all have problems such as acid splash, hydrochloric acid volatilization, and danger to health. The waste liquid must also be collected and proc

Abstract

The invention discloses an automatic cleaning device and method for a scale layer on the inner wall of a heat exchange tube of thermal equipment. According to the device, a chemical preparation assembly is used for preparing chemicals, a controller is used for controlling a first flow regulating valve and a second flow regulating valve to be opened and closed, the functions of automatically feeding a cleaning agent, automatically controlling the cleaning time and automatically collecting acid pickling waste liquid are achieved, the situation that experimenters make close contact with acid liquor in the cleaning process is avoided, the harm of acid liquor splashing and the like to the human body is prevented, the occupational health safety level is improved, operation is flexible and convenient, and the cleaning efficiency and safety are improved.

Description

Technical field[0001]The invention belongs to the field of chemical analysis of the inner wall of metal materials, and particularly relates to an automatic cleaning device and method for the inner wall of a heat exchange tube of a thermal equipment.Background technique[0002]During regular maintenance of thermal power generating units and steam power equipment, chemical inspections are required to grasp the corrosion, scaling or salt accumulation of thermal equipment, and to evaluate whether the water treatment methods adopted by the units during operation are reasonable and whether the monitoring is effective. Propose improvement measures to ensure the safe and economic operation of the unit. One of the important tasks is to inspect the pipe cutting on the heating surface of the thermal equipment at all levels. Pipe cutting inspection includes scale measurement, recording and analysis of internal surface corrosion and scaling conditions, etc. For water wall pipes, economizer pipes, ...
