Description
Technical field
This utility model is related to heat exchanger, particularly a kind of plate type heat exchanger descaling equipment.
Background technology
Plate type heat exchanger is a kind of high-efficiency heat exchanger popularized rapidly over nearly 10 years, compared to traditional shell-and-tube heat exchanger,
Plate type heat exchanger mainly has heat transfer coefficient height, logarithmic mean temperature difference (LMTD) is big, floor space is little, lightweight, price is low, terminal temperature difference
The advantages of little, achievable medium heat exchange and malleable heat exchange area or path combination, in industries such as electric power, heat supply, chemical industry
It is widely used.All there is scale formation in plate type heat exchanger at present, cause heat transmission equipment easily to block after fouling, corrosion resistant
Corrosion is poor.Following factor can cause fouling of heat exchangers：1st, recirculated water, secondary network source of recycled water is generally surface water or underground
Water：Earth's surface hardness of water is generally 6mgN/L--8mgN/L, and underground hardness of water is generally 14mgN/L--20mgN/L.In water
Calcium and magnesium heavy carbonate is decomposed into lime deposit and soft unbodied magnesium hydroxide after heated.These precipitate, wherein one
Part adhesive, on the larger heat exchanger heating surface of heat intensity, forms hard or soft incrustation scale, and another part then suspends
Recirculated water circulates.If water circulation is bad, when flow velocity is relatively low, these float are just deposited on heat exchanger surface, shape
Become secondary incrustation scale.2nd, impurity enters pipeline, inevitably has impurity to enter pipeline in work progress, including welding rod remnants pipe nipple
With debris such as welding slag, sand, soil, during operation, impurity enters heat exchanger with recirculated water and results in blockage.3rd, inner-walls of duct gets rusty, and forms ferrum
Rust mud results in blockage, and water oxygen dissolubility is higher, and in pipeline, oxygen is in point-like, layer corrosion to corrosion of metal.When pipeline runs
When, rust enters heat exchanger with recirculated water, is combined with the incrustation scale on heat exchanger plate surface, forms the incrustation scale piece of chocolate, makes
Heat exchanger flow area diminishes.
So that heat transfer efficiency declines after plate type heat exchanger generates incrustation scale, recirculated water circulation area diminishes, and circulating resistance increases
Greatly, equipment dirty often increases 1mm, and the coefficient of heat transfer declines 9--9.6%, and energy consumption will increase by more than 10%, from thus lead to be entirely
The operation energy consumption of system increases considerably, and heat exchange cost increases.The not only waste of cause the user heat energy, affects economic benefit, also
Bring a lot of difficulties to running, safeguarding, overhaul.Shorten service life of equipment, fouling will produce serious underdeposit corrosion, particularly
Chloride ion produces Pinhole-shaped corrosion to plate, causes the burn into seepage of equipment, so that heat transmission equipment service life is shortened, or even leads
Heat exchanger is caused to scrap in advance.Because plate is very thin, during cleaning hard scale, plate is yielding, and seal washer easily damages；
For ensureing back packing quality it is necessary to change, maintenance is costly.Maintenance difficulty is big costly, and current descaling method is to change board-like
Hot device disintegrates, pickling or manual cleaning piecewise, and scale removal difficulty is big, will change the plate of sealing strip and leakage during assembling, and assembling is easily
The probability of leakage is big, and maintenance is costly.Also there is the method using ultrasound wave descaling at present, but ultrasonic activation is only capable of incrustation scale shakes
Pine, shake and split, the incrustation scale volume after splitting of shaking is still larger, and the waterway channel in plate type heat exchanger is very narrow, and in plate type heat exchanger
Current are more slow, and the larger incrustation scale of such volume cannot be taken out of heat exchanger by current, easily block plate type heat exchanger.
