Description

Technical Field

[0001] The utility model relates to the technical field of cleaning and scale inhibition, in particular to boiler cleaning and scale inhibition equipment. Background Art

[0002] Existing boiler cleaning and scale inhibition equipment removes dirt by adding scale inhibitors to react with the dirt for decomposition. However, the operation is relatively complicated and takes a long time during its use. For example, a Chinese patent discloses a "wall-mounted boiler cleaning device" with an application number of "CN201920216644.2". This device includes a reaction chamber, a reaction chamber is provided inside the reaction chamber, and first stainless steel pipes connected to the reaction chamber are fixedly installed at both ends of the reaction chamber, and the other ends of the two first stainless steel pipes are respectively installed with a first stainless steel bellows and a second stainless steel bellows. A second stainless steel pipe connected to the reaction chamber is fixedly installed at the upper end of the reaction chamber, and a plastic high-pressure hose is installed at the other end of the second stainless steel pipe. This device has a simple structure, good cleaning effect, no other power is required, energy-saving and environmentally friendly, and waste liquid can be reused. After cleaning, the heat exchange performance of the main heat exchanger is improved, the pipelines in the furnace body are unobstructed, the friction resistance of scale to the stator and rotor of the circulating pump is reduced, and the service life of the overall equipment is delayed. However, during its use, the scale inhibitor takes a long time to completely react with the scale, and the dirt is relatively thick and easy to react incompletely, which reduces the cleaning efficiency and wastes cleaning time. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art and provides a boiler cleaning and anti-scaling device. By injecting water and anti-scaling agent into the water injection pipe, the water and anti-scaling agent are sprayed onto the inner wall of the boiler through the nozzle, so as to prevent the electrochemical reaction and corrosion generated when the metal contacts with water. By generating a protective film, the corrosion rate of the metal in water is reduced, and the loss and maintenance cost of the equipment are reduced.
