Description
Technical field
The present invention relates to filter, particularly a kind of spiral plate type non-scaling heat exchanger.
Background technology
Heat exchanger is Appropriate application and the key equipment saving the energy, tap a new source of energy, and is the important industrial production integrating energy-saving and environmental protection, high-tech content, high added value. Heat exchanger of a great variety, with regard to heat exchange efficiency height, what commonly use on market is plate type heat exchanger, wherein processing is simple, heat exchanger efficiency certain High Temperature High Pressure high, resistance to relative to having other heat exchanger for spiral heat exchanger, is widely used in fields such as thermal power generation, petrochemical industry, pharmacy.
Fouling is a kind of very general phenomenon, it is present in nature, daily life and various industrial processes, particularly in various heat transfer process, once fouling, the performance of spiral-plate heat exchanger high efficient heat exchanging just completely loses, in dismounting frequently or cleaning, and not only major injury heat exchanger, and affect the properly functioning of production, increase environmental pollution and drain on manpower and material resources simultaneously.
The industrial revolution is over more than 200 year, dirt kind, fouling reason have all been carried out sufficient research by people, wish enjoy water resource to we bring all convenient while, eliminate the worry of dirt, also diversified preventing fouling it is proposed, the cardinal principle of these technology is: by method chemically or physically, and one is the quantity stopped or reduce and become dirt material in heat-exchange working medium, thus avoiding fouling or delaying fouling; Two is the molecules align form changing heat-exchange working medium, to reach antiscale or to delay the purpose of fouling. Owing to the formation influence factor of dirt is extremely complex, facts have proved, these preventing foulings can only play certain time delaying dirt to produce, because heat exchange wall now is in passive state, wait dirt glue pay and generate, these conventional Anti-fouling Technologies are a kind of passive antiscaling methods, and this method cannot stop the generation of dirt at all.
Dirt is the non-conductor of heat, and its heat conductivity is 0.1741.163W/ (m DEG C), is only the 1/50��1/30 of steel, even if schmutzband thickness is little, also results in heat transfer coefficient and reduces. According to the authoritative statistical data that " industrial energy " magazine provides, the dirt matter deposit thickness in heat transmission equipment and pipeline every year is at least at more than 4mm, and heat transmission equipment dirty often increases 1mm, and the coefficient of heat transfer declines 9��9.6%, and energy consumption will increase by more than 10%.
At present, Shanghai Xingquan Electric Power Technology Co., Ltd have developed a kind of energy wave Anti-fouling Technology, it is applied in fields such as petrochemical industry, electric power, Coal Chemical Industries, and achieve good tartar preventing iron tartar effect, it is possible to chemical pickling method maybe can not cannot be cleared up the heat exchanger dirt of removing and clean out. this energy wave descalling technique operation principle is to be coupled to by high-frequency energy ripple on each metal heat-exchange face, the particle (or atom) making heat exchange surface produces the elliptic motion of high frequency short arc, the result of this motion is to make heat exchange surface produce huge shearing force, has efficient removal effect to adhering to superincumbent various dirts. the effect of this energy wave antiscaling, descaling has broad spectrum activity, and it will not be subject to the impact of all factors such as heat-exchange working medium state, can ensure good tartar preventing iron tartar effect, but there is certain relation with the structure of heat transmission equipment, although this energy wave descalling technique ensure that various metallic recuperator non-scaling or effective On Line Foul Removing Technology, but the cost that the metallic recuperator of different structure applies this descalling technique is different, the heat exchanger such as having is when applying this descalling technique, the loss of energy wave is relatively larger, whole energy wave effectively can not be coupled on heat exchange surface, but have most energy loss, this situation is accomplished by the quantity installing energy wave generating apparatus more and can be only achieved purpose, which adds the cost of antiscaling, descaling, research and field practice by experiment, the present invention proposes a kind of spiral plate type non-scaling heat exchanger, and it remains the advantage of spiral-plate heat exchanger, has carried out the improvement of processing technique simultaneously, to guarantee effective utilization of energy wave, thus the purpose of non-scaling when realizing low cost.
The production technology of current spiral-plate heat exchanger and construction features are not suitable for installing energy wave antiscaling and descaling device, reason is that spiral-plate heat exchanger refers to and is made up of two parallel metal roll bendings, with the mode uniform welding support column of electro-fusion welding on metal plate, weld again after two side edgefolds of metallic plate, the few size of thickness difference of weld bond thickness and metallic plate. the thick end of currently used metallic plate, is typically no less than 5mm, distance between heat exchanger plates is not less than 15mm, certain heat exchange efficiency is caused to decline, the result of this processing technique is: complex process, working (machining) efficiency is low, many with steel, volume is big, heat transfer effect is undesirable, more crucially the weld bond of the both sides of metallic plate is to connect each metal heat-exchange face " bridge ", but the thickness of its thickness and heat-transfer surface is basically identical, if energy wave is transmitted by it, its bringing onto load energy is excessively poor, the effect of the antiscaling, descaling of energy wave can not be given full play to.
