Description

A kind of circulating scale cleaning equipment

Technical field

The utility model relates to scale cleaning technique field more particularly to a kind of circulating scale cleaning equipments.

Background technique

After the equipment longtime running such as cooler, heat exchanger, radiator, the cooling inside pipe wall of equipment can generate scale, it will The sectional area of water pipe is reduced, the resistance for increasing water circulation can block pipeline, serious shadow with the gradually thickening of scale crust The cooling effect and heat exchange efficiency for ringing equipment can also cause local corrosion etc. and influence making for equipment when fouling face is uneven Use the service life.Therefore, scale is very harmful to the safe operation of equipment.

The method of scale includes two kinds in traditional removing equipment: artificial scale removal, chemical cleaning scale removal.Artificial scale removal is main Using machine tools such as wire brushes, the mechanical failure to equipment pipe is relatively easily caused, and be difficult to thorough cleaning, time-consuming length, effect Difference.Chemical cleaning technique is mainly to be passed through using cleaning solution made of the inorganic acid or organic acid having compared with strong corrosive Water pump is connect with equipment to be cleaned by pipeline, and the water inlet pipe of water pump is placed in the water tank for filling cleaning solution, equipment to be cleaned Water outlet is placed in water tank, forms scavenger circuit.

The principal element for influencing scale removal effect in cleaning process includes: the use temperature of chemical, chemical Use proportion, and using chemical cleaning way.(1) scale removal effect is the most when 40-50 is spent for chemical Significantly, but the equipment itself of existing chemical cleaning scale is without heat source, or uses included heat source in cleaning process to temperature The control inaccuracy of degree, the scale removal effect that can be substantially reduced in cleaning process.(2) existing chemical cleaning equipment often by The data provided on the nameplate of equipment to be cleaned determine the water consumption in cleaning process, and then determine cleaning agent usage amount, The cleaning agent matched accordingly with optimal cleaning effect is matched, but the actual use amount of water can be wrong in actual operation Difference, will cause be added cleaning agent amount it is excessive, cause the waste of cleaning agent or cleaning agent amount deficiency to cause cleaning effect not It is ideal.(3) existing chemical cleaning equipment often removes dirt using circulation flushing mode always.But intermittent first punching Wash the cleaning way impregnated again, i.e. pump operation for a period of time, then flushing liquor circulation flushing again stops working water pump, Through immersion after a period of time, the cleaning effect of scale can be further promoted, but the operating of water pump is controlled by power supply , practical operation requires to be manually operated to the operation of electricity power-off, and cumbersome repeated workload is huge.

Furthermore existing scale cleaning equipment, which uses, configures the chemical cleaning solution accordingly matched in external container in advance, then will Configured chemical cleaning solution is added in the liquor box of cleaning equipment, increases operating procedure, increases workload.And it is following In ring cleaning process, entire wash cycles can be will affect with the scale and impurity peeled off in the chemical cleaning solution of recycling The recycling effect of chemical cleaning solution in the process can also cause certain blocking to unit fixed on water pump suction and outlet conduit.
