Description
Technical field
The invention belongs to technical field of heat exchangers, are related to a kind of lamella heat exchanger more particularly to a kind of non-scaling plate shell
Formula heat exchanger.
Background technology
Dirt refers to gradually formed on the heat exchange surface being in contact with unholiness fluid one layer of solid matter.Dirt is universal
It is present in many fields of process industry, the fouling of heating surface and heat-transfer area is just normal as equipment is perplexed in heat exchange process
One of main problem of operation.Dirt causes the thermal efficiency to decline, and adds heat transmission resistance, and energy consumption increases, and pipeline is blocked when serious
Even cause the serious consequences such as the bursting of boilers.Dirt annoyings people always over the past thousands of years, either in the past or present, is hair
Country or developed country, all deeply hurt, still thoroughly solve the problems, such as this without effective ways so far in exhibition.Augmentation of heat transfer with
Prevent dirt from having effectively formed two general orientation of heat transfer research, and the presence of dirt causes various augmentation of heat transfer means to receive
Limitation, dirt is early, and oneself is confirmed as letter main bugbear to be solved in terms of heat transfer.
For many years people to dirt kind, fouling reason all has conducted a thorough research, it is desirable to enjoy water resource to we with
Come it is a variety of eliminate the worry of dirt, be also proposed diversified preventing fouling while facilitate, it is big can be substantially divided into two
Class：Chemical method and Physical.However technology (such as ion exchange, online dosing, the electric field for the descaling and antiscaling industrially applied at present
The technologies such as technology, magnetic field technique, frequency conversion resonance) having focused in the physical property for changing heat-exchange working medium descaling and antiscaling, be exactly
Change the state of heat transferring medium by approach physically or chemically, for example lower the hardness of water, reduce into dirty probability, increase dissolving
Degree changes the methods of dirty matter composition, and heat-exchange working medium is allowed not form on heat exchange wall dirt in heat transfer process or delay to form dirt
Dirt.Heat exchange wall surface at this time is in passive state, that is, waits dirt and pay and generate to glue.These methods there is without the dirty phase it is short,
The problems such as energy waste, serious operating cost height and environmental pollution.But also there are descaling and antiscaling effect by water quality, temperature,
The factors such as pressure, flow velocity, caliber influence the problems such as big, and heat transferring medium has anti-under phase changing environment especially on vapor heat exchanger
Dirty scale removal is just more difficult, these previous descaling and antiscaling methods are faced with more challenges at many aspects.
Physical scale removal, antiscale：Past common general has electromagnetism, permanent magnetism, Qiang Ci, high frequency, electrostatic, the frequency conversion resonance etc. more
The descaler of kind form, is commonly called as electronic water or electronic descaling.Up to the present people have gone through the research of electronic descaling
Half a century, electronic descaling iterate, and opinions vary for scale removal effect, and often this place is effective, and the other side may not imitate
Fruit, effect is good when just loading onto, and with a period of time, effect is with regard to unobvious, although namely why chemical cleaning is deposited for this
Such or such the problem of, but the key point that must also largely use at present.
Although there is the antiscaling, descaling measure of various chemical methodes and physical method, in industrial process stream, due to dirt
The harm that dirt generates also constantly is occurring, and causes huge energy waste and many production accidents.This is because people
Thinking enters one for many years by the cured one mode of researchers, is exactly the shape want always by changing heat-exchange working medium
State reaches antiscale purpose, since this cured thoughtcast also can not just break through the field of current preventing fouling.Because
Formation influence factor (degree of supersaturation of heat-exchange working medium, flow velocity, body temperature, pH value, crystallization, sedimentation, polymerization, the micro- life of dirt
Object growth, burn into particle, chemical reaction, solidification and mixed dirt etc.) very much, it is a very complicated physics, chemical mistake
Journey is a multi phase state, the dynamic heat transfer and mass transport process of unusual physical property, and with fluid structurecoupling phenomenon, it is in momentum, energy
It is carried out during amount and the simultaneous Multiphase Flow of mass transfer, also relates to chemical kinetics, glue in many cases
Body chemistry, statistical mechanics and the problems such as to Surface Science hydrodynamics and thermal conduction study, also comprising salt dissolving in water and material
Corrosion and microorganism breeding, changed along with interface temperature, depositing temperature, the fluid between different mechanisms dirt flow through
The speed of hot surface and fluid behaviour etc., and for Different field heat exchanger, also influenced by more a variety of factors, such as fluid
Physical parameter, wall temperature, wall surface material, surface roughness, fluid flow rate, turbulence intensity, the shear stress of fluid and solid wall surface
Deng, above-mentioned each parameter will also at any time, the variation of place and service condition and change.
In order to solve the problems, such as fouling, mitigate influence caused by dirt, engineers and technicians and scientists are " after preceding servant
After " the research dirt origin cause of formation and form rule, it is desirable to be able to effective pre- antifouling generate simultaneously controls its growth, for industry
Design provides reliable basis, to suit the remedy to the case, shoot the arrow at the target take anti-scaling measures, but regrettably so far still without one
A result of study is universally accepted.
All the time, in order to mitigate the influence brought to industrial production of dirt, people in the design of heat exchanger still
The conservative approach of Redundancy Design to be continued to use, many times takes the mode of " the using and the reserved ", this not only causes the huge waste of material,
And do not mitigate scaling degree in many cases.
According to the whole world to the achievement in research of dirt from the point of view of, the research of dirt is still within foundation phase at present, such as right
The physical data of dirt is also insufficient, such as the settled density of dirt, thermal conductivity, nutrient diffusion coefficient.In this case, by changing
The mode for becoming heat-exchange working medium state is nearly impossible to reach antiscaling, descaling purpose.
Heat exchanger is reasonable utilization and key equipment that is energy saving, tapping a new source of energy, is collection energy-saving and environmental protection, high-tech
In the important industrial production of one, it is present in all occasions of industrial processes and living needs, example for content, high added value
As heat transmission equipment accounts for 45% or so in petrochemical system.But the problem of fouling of heat exchangers, perplexs the section in industrial process always
The progress that can be lowered consumption.
Dirt causes the thermal efficiency to decline, and energy consumption increases, and pipeline is blocked when serious and even causes the serious consequences such as the bursting of boilers.
According to《Industrial energy》Magazine provide authoritative statistics, dirty matter every year the deposition thickness in heat transmission equipment at least 4mm with
On, and heat transmission equipment incrustation often increases 1mm, the coefficient of heat transfer declines 9~9.6%, and energy consumption will increase by more than 10%.
The harm and adverse consequences that fouling of heat exchangers is brought include：Investment cost increases；Energy expenditure increases；Maintenance clean
Expense increases；Product yield, quality reduce；Disposal of pollutants increases；Cause metal superheat strength reduction；Service life of equipment contracts
It is short；Water Xun Huan is destroyed, is caused the accident；Heat transmission equipment maintenance amount increases；Limit development of new techniques.
Developed country's rough estimate in 2007, increased expense accounts for the 0.25% of GDP then due to dirt.China is energy
Source consumes big country, and the production technology and manufacture level of heat transmission equipment fall behind relatively, and the economic loss caused by dirt is far above hair
Up to country.Therefore develop and production anti-tartar heat exchanger has great reality meaning in terms of dirt harm and energy conservation and environmental protection is mitigated
Justice.
