Online precision chemical descaling device and method of industrial tube nest type water cooler

Abstract

The invention discloses an online precision chemical descaling device and method thereof of an industrial tube nest type water cooler. A descaling agent distribution device and a servo control device are arranged outside a water chamber of the water cooler, an underwater positioning device and a descaling agent injection device are mounted in the water chamber of the water cooler, the underwater positioning device is connected with the servo control device through a waterproof cable, the descaling agent distribution device is connected with the descaling agent injection device through a guide tube, the servo control device transmits commands to the underwater positioning device, descaling agent injection nozzles on a driving support and orifices of cooler heat exchange tubes are docked, and the descaling agent distribution device supplies descaling agent to the descaling agent into the descaling agent injection nozzles. After set washing and soaking time is up, the descaling agent injection nozzles are separated from docking with the orifices of the cooler heat exchange tubes under drive of the servo control device and automatically move to inlets of the next group of cooler heat exchange tubes. On the premise of zero emission, reliability of operating of the equipment is improved, cleaning cost of the cooler is greatly reduced, and cleaning effect is greatly improved.

Description

technical field [0001] The invention belongs to the field of chemical cleaning of industrial heat exchangers, and is a new technology for energy saving and emission reduction of heat exchangers. Specifically, it uses underwater positioning robot technology to realize online cleaning of scale and stains on heat exchange tubes in tube water coolers. A technical method of chemical precision cleaning. Background technique [0002] The shell and tube water cooler is one of the main auxiliary equipment widely used in industrial sectors such as power, chemical, petroleum, and atomic energy. It is responsible for the important cooling tasks of various power, electrical, mechanical and chemical reaction equipment. Its working performance is good Damage has an important impact on the safety and economic operation of enterprises. In the process of heat transfer, scale and stains are easily formed on the inner wall of the water side of the heat exchange tube in the tube-and-tube water ...

AI Technical Summary

Problems solved by technology

[0006] The main problem of this cleaning method is: the added chemical cleaning agent is diluted by a large amount of circulating water in the circulating water pool, and it is far from reaching the cleaning concentration when it reaches the heat exchange tube of the condenser, and a large amount of chemical cleaning agent is wasted.
