Technical field
A kind of heat exchange pipe heat exchanger is the utility model is related to, more particularly to a kind of heat exchange pipe heat exchanger eddy flow good antiscale property
Device.
Background technology
At present, the heat exchange pipe heat exchanger used in the industries such as electric power, chemical industry, metallurgy, with condenser, oil cooler,
Heat exchangers for district heating is most widely used, and due to being influenceed by rivers sea and quality of groundwater and water temperature, heat transfer tube wall is easily produced
Raw fouling, and gradually thicken over time, heat exchange has been obstructed, has influenceed to exchange heat（Cooling）Effect, drop heat exchanger efficiency
It is low.Traditional solution method is cleaning during shutdown, and it is included to soft dirty artificial cleaning and the Chemical cleaning to hard scale；The fifties
After invented the cleaning device such as rubber ball cleaning and rotation long filament hairbrush cleaning, to improve the thermal efficiency of steam turbine, but effect is equal
It is not fully up to expectations.
By taking plant condenser as an example, scale removal, good antiscale property processing are carried out using a variety of methods in production, such as periodically parking is clear
Wash, ball cleaning apparatus, rotation long filament hairbrush, bipolar electrode reverse osmosis unit etc..Regular cleaning during shutdown, general 1 year twice, clearly
The time is washed as three or five days or so, so not only causes parking to lose, also to pay expense, the particularly hard scales such as artificial, material
Pickling, infringement is produced even if the proper heat pipe that can also exchange is handled, influences heat exchanger tube service life, such as dealing with improperly directly causes to coagulate
Vapour device heat exchanger tube is scrapped；For ball cleaning apparatus using at most, ball cleaning apparatus is the equipment that periodically need to often put into operation, and needs specialty
Personnel put into operation, and glueballs loss is also larger, although heat exchanger tube fouling can be prevented, it is cleaned with current in operation,
It is more close to the condenser center section heat exchanger tube cleaning frequency, and the heat exchanger tube in condenser surrounding also wants periodic cleaning, does not
Good glueballs also allows hard scale to block in copper pipe；The cleaning of long filament hairbrush is rotated, is that long filament brush unit is arranged in heat exchanger, by
Poor in the material fatigue resistance that it is used, easily broken, hairbrush and the easily raw dirt of long filament, the effectively cleaning phase is shorter, influences scaling effect.
Although having the device for the good antiscale property effect that heat exchange pipe heat exchanger is realized by helical band in the prior art,
