Description
Technical field
The present invention relates to a kind of Dry ice cleaning efficient detection method.
Background technology
The transformer outdoor application of being everlasting, environment for use can produce larger impact to transformer, after using a period of time, bushing shell for transformer can be subject to contamination in various degree, along with the dirt of accumulation is more and more, may cause bushing shell for transformer generation flashover, because capacity and the scale of now power system are all larger, power failure can bring larger economic loss, therefore after bushing shell for transformer is polluted, can not have a power failure at any time and clean, generally all under the transformer belt electricity condition water clean, when water cleans, the safe operation of electrical equipment brought impact around the spray that splashes can be given, accident easily appears, therefore, some begins to adopt dry ice to clean now, its principle is to flow by compressed-air actuated, dry ice particles is accelerated to the surperficial dirt that transonic speed bump is cleaned, surface dirt suddenly cooling causes surperficial embrittlement, the extremely low dry ice particles of these temperature enters into the pollutant that the crack occurs simultaneously, when the dirt on surface is clashed into, dry ice particles rapidly distillation is gas, and the energy that the air release of distillation is a large amount of is under the effect of this energy, the dirt that will break separates from body surface, Dry ice cleaning can be carried out under electriferous state, has eliminated the loss that transformer has a power failure and causes, and can not cause electric shock accidents simultaneously when cleaning, guaranteed the safety of cleaning, but when using dry ice that the band piezoelectric transformer is cleaned, because the improper meeting of method of operating causes slatterning a large amount of dry ice, can reduce simultaneously the effect of cleaning.
Summary of the invention
The object of the present invention is to provide and a kind ofly can detect the Dry ice cleaning efficient detection method of Dry ice cleaning device under difference cleaning state.
In order to realize purpose of the present invention, the technical scheme of taking is:
A kind of Dry ice cleaning efficient detection method may further comprise the steps:
The dirt kind of a, record object surface to be cleaned and the amount of various types of dirt;
B, unlatching Dry ice cleaning device;
Angle between c, the dry ice flow that changes the Dry ice cleaning device and/or adjusting Dry ice cleaning device supply gas pressure and/or adjusting Dry ice cleaning device top nozzle and the object surface to be cleaned and/or the distance between adjusting Dry ice cleaning device top nozzle and the object to be cleaned, make the nozzle on the Dry ice cleaning device aim at dirt on the object surface to be cleaned according to the requirement after adjusting, elapsed time T records the dirt kind of object surface to be cleaned and the amount of various types of dirt again;
D, the dirt kind of the object surface to be cleaned of a, c step record and the amount of various types of dirt are carried out analytical calculation, draw the cleaning efficiency after the c step changes parameters.
The front and back of the amount by recording object surface dirt kind to be cleaned and various types of dirt change, can draw corresponding cleaning efficiency after each the adjusting, thereby obtain the cleaning method of cleaning efficiency the best, avoided simultaneously the more dry ice of waste, saved resource.
The below further specifies technical scheme:
Among embodiment, described dry ice flow adjustment range is 1.0kg/min～3.0kg/min therein.The too small meeting of dry ice flow causes dirt to can not get effective removing, the excessive cleaning performance of dry ice flow improves the limited waste that can cause simultaneously a large amount of dry ice, the dry ice flow adjustment range is controlled at 1.0kg/min～3.0kg/min can make the dirt on the object surface to be cleaned be cleaned preferably, has avoided simultaneously the more dry ice of waste.
Among embodiment, described dry ice flow adjustment range is 2.0kg/min～2.5kg/min therein.2.0kg/min～2.5kg/min dry ice flow is best results when cleaning.
Among embodiment, described supply gas pressure adjustable range is 0.4Mpa～0.7Mpa therein.Flow velocity when the too little meeting of supply gas pressure causes dry ice to spray from nozzle is lower, thereby do not reach good cleaning performance, supply gas pressure is excessive, higher to the Dry ice cleaning matching requirements, increased cost, the cleaning performance that improves simultaneously is limited, and has caused a large amount of dry ice wastes, the supply gas pressure adjustable range is controlled at 0.4Mpa～0.7Mpa can make the dirt on the object surface to be cleaned be cleaned preferably, has avoided simultaneously the more dry ice of waste.
Among embodiment, described supply gas pressure adjustable range is 0.5Mpa～0.6Mpa therein.When supply gas pressure is adjusted to 0.5Mpa～0.6Mpa when cleaning best results.
Among embodiment, the angle of regulation range between described nozzle and the object surface to be cleaned is 5 °～60 ° therein.Angle between nozzle and the object surface to be cleaned can exert an influence to cleaning performance equally, be the design of acute angle, can make the dry ice particles of at a high speed ejection treat shearing force of cleaning objects surface dirt generation, thereby dirt is peeled off from object surface to be cleaned, improve cleaning performance.
Among embodiment, the angle of regulation range between described nozzle and the object surface to be cleaned is 15 °～25 ° therein.15 °～25 ° angle can make cleaning performance reach optimum state, and in this angular range, dry ice particles can be carried out effective collision with dirt, and dry ice sublimation releases energy after the collision, thereby Fouling Cleaning is fallen.
Among embodiment, the distance adjustment scope of described nozzle distance object to be cleaned is 10～30 centimetres therein.Can be subject to the resistance of air the process that dry ice particles is moved from nozzle to dirt, when the distance of nozzle distance object to be cleaned is larger, kinetic energy when dry ice particles and dirt collision is less, cause cleaning performance to reduce, flashover easily appearred in the bushing shell for transformer annex when distance was too near, increased the danger when cleaning.
Among embodiment, the distance adjustment scope of described nozzle distance object to be cleaned is 18～24 centimetres therein.This flashover can not occur simultaneously apart from dirt is got effective washing.
Advantage of the present invention is:
The front and back of the amount by recording object surface dirt kind to be cleaned and various types of dirt change, can draw corresponding cleaning efficiency after each the adjusting, thereby obtain the cleaning method of cleaning efficiency the best, avoided simultaneously the more dry ice of waste, saved resource.
