Description
Technical field
The invention belongs to water-treatment technology field, and in particular to a kind of water body antiscaling and descaling device and its application.
Background technology
In boiler, cooling tower, heat exchanger and nearly all application for utilizing water to be heated or cooled, fouling
(with calcium carbonate and other mineral forms) are all subject matters.In industrial processes, because water is cheap
And be readily available, water is often used as the carrier of heat transfer.The heat produced in production process passes through a heat
Switch (heat exchanger, condenser etc.) is transferred in cooling water, is then evaporated in cooling tower by water
And distribute heat in nature.The original water in poised state, changes condition in heat-exchanger surface,
Crystallization deposition is easy to, becomes incrustation scale, become industrial harm.
First, incrustation scale is heat-insulated, can reduce heat exchange coefficient, can so increase extra energy ezpenditure；Its
Secondary, incrustation scale meeting blocking heat-exchanger, refrigerator, pump, pipeline and valve, so as to increase pressure, the minimizing of water
The flow of water, cause leakage, even cause thoroughly irremediable damage；In addition, incrustation scale is carried to microorganism
For protection, the hotbed of breeding is provided to microorganism, causes biological pollution and underdeposit corrosion.
The prevention of incrustation scale and removing become the technical problem that must be faced and solve.Process currently for incrustation scale
It is all generally the processing mode combined using antiscale and scale removal, mainly chemical method and two class of physical method.Often
The chemical treatments that sees are mainly and add chemicals in water body, are realized to incrustation scale using chemical reaction mode
Elimination or prevent in pre- waterproof body calcium and magnesium particle to generate corresponding incrustation scale material.But, chemical method one is
Impact of extra these chemical substances that adds to water body or environment, two is that its price is high, causes industrial cost
Notable rising；Three is that elimination effect is also limited, remains a need for further cleaning in many cases.
Physical method generally includes mechanical cleaning mode or by the way of water body filtration.Mechanical cleaning is generally needed
Carry out after shutting down, reduce production efficiency, and cleaning performance have to be strengthened；Prevented by way of filtering
Most of calcium and magnesium particle can be effectively filtered in dirty scale removal, but, as filter core needs periodic replacement so that
Actual cost is greatly promoted, and is filtered or delayed water velocity, causes time formation efficiency to reduce.
At present, occur in that carries out the technical scheme of antiscaling, descaling using ultrasonic wave or magnetic means, i.e., using ultrasound
The mode of ripple is processed to incrustation scale, is removed incrustation scale or is delayed the generation of incrustation scale, or utilizes magnetic fields by water
Calcium ions and magnesium ions in body are magnetized, so as to prevent fouling.Above-mentioned technological means can preferably be realized antiscale and remove
Dirt, but the ultrasonic unit due to needing additional special and magnetizing assembly so that equipment overall structure is multiple
Miscellaneous, it is not suitable for commercial Application is needed, and cost can be increased, in addition ultrasonic wave or magnetization can be to water body or rings
Border can produce certain impact so which is using being restricted.
A kind of descaling and antiscaling device is disclosed in Chinese patent literature CN201320794373.1, and the device is outside
Spiral alloy sheet is installed inside shell, crust of the device two ends are connected with inlet channel by joint, and the spiral is closed
Gold plaque adopts the fluid origin plate shape of high potential metal alloy, then cuts into sheet, then turns round along long axis centerline
Three-sixth turn curl.When current are through spiral alloy sheet, each molecule in water is in the mistake of helical flow
Contact with spiral alloy sheet in journey, when contact, high rest potential spiral alloy sheet is connect with the calcium ion in water
Touch and potential difference is produced, the potential difference acts on calcium ion so as to generation calcium carbonate smoothly can not be combined with carbonate
Precipitation fouling, realizes the purpose of good antiscale property and scale removal.The device can in the case of impact production is avoided as far as possible,
Using alloy and the effect of calcium ion in water body, so as to prevent the generation of incrustation scale, imitate with preferable antiscaling, descaling
Really.But, the device yet suffers from following problem：1) impact of the spiral alloy chip architecture to current,
I.e. the alloy sheet reverses shaping by tabular, and which has certain impact as water stream channel to water body flow speed,
Efficiency is caused to reduce；2) flow passage structure of alloy sheet cannot ensure that each molecule in water can be connect with alloy sheet
Touch, so as to antiscale and scale removal effect can be caused to be affected；3) fail in the device to alloy sheet composition and its
Component is defined, and Conventional alloys are general with hydrone action effect, and therefore the device is to the actual scale removal of water body
Antiscaling effect is also to be hoisted.
