Description
Technical field
The present invention relates to cleaning device field, particularly, relate to a kind of chiller cleaning unit.
Background technology
Condenser is in running, and along with the splashing of cooling tower is evaporated, cycles of concentration rises, and easily becomes the calcium ions and magnesium ions content of dirt more and more higher in cooling circulating water.When cooling water flow is when the heat exchanger tube of condenser, form hardness dirt.The oxygen be dissolved in cooling water also can cause metal erosion, and corrosion product iron rust forms rust deposite.The glutinous mud that dust in air enters into circulation and microbial metabolism generation along with cooling tower forms dirt.In cooling circulating water, the slowest place of flow velocity is exactly the heat exchanger tube of condenser, and these hardness dirt, rust deposite and dirts form compound scale in condenser heat-exchange pipes, cause condenser heat transfer effect to decline, when fouling is serious, meeting cramming, makes heat transfer effect ineffective.
There is a lot of problem when cleaning equipment in cleaning way traditional for a long time such as mechanical means (scrape, brush), water under high pressure, Chemical cleaning (pickling) etc.: needs stop cleaning; Mechanical cleaning, to the destruction of Water in Condenser side ducts diaphragm, thoroughly can not remove the deposits such as incrustation scale; Chemical cleaning acid solution causes corrosion to form leak to equipment, and residual acid produces anticaustic or underdeposit corrosion to material, finally causes more exchange device, and in addition, cleaning waste liquid is poisonous, needs substantial contribution to carry out wastewater treatment.
Chiller cleaning unit is injected into by the rotating wash bowl of some in the water side heat exchanger tube of condenser, by doing mechanical wiping to condenser heat-exchange pipes inside pipe wall, so ceaselessly condensation copper pipe inwall is cleaned, make the dirt in water, incrustation scale, bacterium algae have no chance copper pipe inwall attachment, cleaning rate 100%.Pollution-free, radiationless, corrosion-free, improve the service life of main frame and water system metalwork.And without the need to shutting down, do not affect the continuous operation of condenser.
Its working mechanism selects suitable sponge glueballs, the hygrometric state diameter of ball than by scavenge pipe internal diameter more bigger (about 1-2mm), and hygrometric state proportion and aqueous phase near.Glueballs, under the current slightly higher than circulating water intake pressure drive, enters condenser.Because of the elastomer that glueballs is micropore softness more than, under the effect of recirculated water inlet and outlet pressure difference, be extruded by cooling tube, once wiping is smeared to cooling tube internal diameter, inside pipe wall dirt is taken out of with current, glueballs enters ball collecting device with recirculated water through outlet pipe, under the obstruction of ball screen plate, glueballs is separated, extracted out by Rubber ball pump and come back to condenser, so move in circles to condenser realization cleaning automatically continuously.
Current chiller cleaning unit is divided into following two classes:
1, Rubber ball pump continuous wash type: adopt the Rubber ball pump of large runner as cleaning power source, ball supercharging together with the water in system of the ball collecting device expert machine of leaving condenser water end is delivered to the water inlet end of condenser, rotating wash bowl enters in the heat exchanger tube of Water in Condenser side and cleans together with cooling water.Circulate and so forth.Glueballs delivery pump is the power-equipment making glueballs carry out constantly circulation in rubber ball cleaning system.This pump is a special accessible centrifugal pump, and its two panels impeller forms tubular conduit.It has the advantages that not block ball.There is the feature of wide runner, the slow-speed of revolution, little, the applicable long-time continuous operation of volume simultaneously.But Rubber ball pump will have enough lifts and flow, pump inlet tube connector is tight, normally runs to keep rubber ball cleaning system.Installed power and operate power high, and glueballs with also in the pump housing, frictional impact can be produced with impeller and cause glueballs to damage.Thus run power consumption and glueballs loss high.
2, centrifugal water pump single is interrupted cleaning-type: during cleaning, will store up ball device and centrifugal pump water inlet end valve closing, by the water of centrifugal pump supercharging, the cleaning glueballs be stored in ball device is headed into the water inlet end of condenser.Ball collecting device is entered into after rubber ball cleaning.After completing once cleaning, then start second water pump and be drawn into Chu Qiuqi through the glueballs be stored in ball collecting device.Switching electrically operated valve and water pump complete cleaning and receive ball and so forth.This type of cleaning device needs the frequent water pump and the motor-driven valve that switch and open and close correspondence, and service life is short, and cannot complete continuous wash.
As can be seen here, above-mentioned existing chiller cleaning unit, in structure, method and use, obviously still has inconvenience and defect, and is urgently further improved.How to found and a kind ofly extend rotating wash bowl service life, continuous wash can be realized and automatically receive the chiller cleaning unit of ball, become the target that current industry pole need be improved.
