Problems solved by technology

However, the effect of chemical cleaning is often very unsatisfactory, and the scale removal rate is less than 50%, and it may also corrode the boiler and accelerate the destruction of the boiler
At the same time, chemical cleaning agents need a lot of water for descaling, and the use of chemical cleaning agents will cause serious pollution to the environment

specific Embodiment 1

[0020] Specific embodiment 1: see attached figure 2 , which is a schematic diagram of the present invention specifically applied to boiler scale removal. The electric control box (2) controls the stretcher (11) to move along the guide rod (9) to reduce the opening degree of the umbrella-shaped rotary spraying device (1), so that it enters the boiler with a small posture; the umbrella-shaped rotary spraying device After the device (1) enters the boiler, the stretcher (11) moves along the guide rod (9) again so that the umbrella-shaped rotary spraying device (1) is opened to prepare for cleaning. The water pump (7) pressurizes the water in the water storage tank (8) and outputs it, and the output high-pressure water jet is introduced into the guide rod (9) through the water jet interface (5), and then drained to the diverter ( 13), and then reach the annular nozzle device (19) through the guide pipe (14), the guide chamber (18), the annular telescopic tube (16), etc., and then...

Abstract

The invention discloses a water-jetting limescale removing method and device. The water-jetting limescale removing device comprises an umbrella-shaped rotary spraying device, an electric control box, a motor, a rotating device, a water-jetting connector unit, a guide rod expansion and contraction device, a water pump, a water storage tank and a guide rod, wherein the umbrella-shaped rotary spraying device comprises a tensioner, an articulation ring, a flow divider, flow guide tubes, pull rods, annular telescopic tubes, cavitation nozzles, flow guide cavities and annular nozzles; the electric cabinet controls the tensioner to regulate the opening degree of the umbrella-shaped rotary spraying device, so that the umbrella-shaped rotary spraying device can enter an object to be cleaned at a small attitude; the electric control box controls the tensioner again to enable the umbrella-shaped rotary spraying device to expand to be cleaned; and the umbrella-shaped rotary spraying device enables the water-jetting limescale removing device to complete the all-round and no-dead-corner limescale removing operation with the help of the rotation of the rotating device and the expansion and contraction of the guide rod. The water-jetting limescale removing method and device have the advantages as follows: the limescale removing efficiency is high, no pollution is caused, and the adaptability is strong.

Description

technical field [0001] The invention relates to the technical field of scale removal, in particular to a water jet-based scale removal method and device. Background technique [0002] Scale is originally the product of precipitation of heavy metals, calcium salts, dust, germs, and insect egg corpses mixed in water. Its main components are calcium carbonate and magnesium hydroxide. The generation of scale will cause serious adverse effects on people's production and life, especially in boilers, the generation of scale will often affect its safe operation, and what's more, it will cause irreparable losses to people's lives and property safety. Boiler is a special equipment widely used in industrial and agricultural production and people's life. It is one of the important equipment for producing steam or hot water, and its energy transfer medium is water. The quality of boiler water has a great influence on its safe operation and energy consumption. When the water quality of ...
