Description

Full voltage type on-line auto-cleaning condenser system and preparation method and cleaning method

Technical field

The present invention relates to a kind of system of cleaning the heat exchanging pipe inwall, relate in particular to a kind of full voltage type on-line auto-cleaning condenser system and preparation method and cleaning method.

Background technology

After the long-time use of heat-exchange device, the inwall of heat exchanging pipe can deposit one deck dirt matter layer, have a strong impact on the heat transfer efficiency of heat exchanging pipe, the scale problems puzzlement equipment control of heat-exchange device and the emphasis difficult problem of maintenance, particularly require under the situation of heat-exchange device long-term operation, it is more outstanding that problem seems.

The inwall of condenser heat-exchange tube after running a period of time can pass effect because of underlying cause influences its heat:

1, heat-exchange tube encrustation

Have salts substances such as a large amount of calcium carbonate, magnesium carbonate in the water body, cause the inside pipe wall fouling, cause the heat exchanger effectiveness of heat-exchange tube obviously to reduce, the temperature of water body and pH value also directly influence the speed of fouling;

2, the corrosion of heat-exchange tube inwall

The heat-exchange tube inwall can be assembled, adhere to organic thin films such as many organic substances, bacterium, phycomycete, causes the obvious reduction of effectiveness of heat exchanger;

3, the corrosion of heat-exchange tube inwall

Cooling water body and air carry out heat exchange in cooling tower, latent heat in water (1atent heat) is taken away by air, also have many air to dissolve in the water body, be dissolved in the oxygen in the water body, the oxidation reaction that directly produces chemistry in the condenser with the heat-exchange tube inwall that flows into along with water body causes corroding the heat-exchange tube inwall.

Usually the cleaning method of heat-exchange device has three kinds of methods: chemical method, water flood and purpose-built washing equipment.These three kinds of methods could be implemented after all needing to shut down, and use time-consuming effort again, but cleaning are thorough inadequately again.Stop work to clean, can not solve in the equipment running process because the caused heat transfer efficiency of fouling descends, equipment capacity reduces, energy consumption rises and underdeposit corrosion, have a strong impact on the service cycle of equipment, and recondition expense is too high.Throw in water quality stabilizer and antisludging agent in the recirculated water, because circulation is big and the leakage of water system, all kinds of impurity are more, the effect of medicament delivery is generally undesirable, make with medicament clean condenser pipe, can cause the nonvolatil damage of tube wall, shorten the service life of equipment.

Though add the dirt accumulation speed that the medicine method can be slowed down the heat-exchange tube inner wall surface, can cause the corrosion of heat-exchange tube inwall, the inside pipe wall smoothness is reduced, be as good as with the increase of sealing factor, in addition, environment suffers the problem secret worry of chemical contamination also serious day by day, suffers dirt sick.
