Description
Technical field
The utility model relates to the waterproof scale device of solar water heater, belongs to technical field of solar water heaters.
Background technology
Human utilization to solar energy is historical the same long with the whole mankind's history.Solar energy can be converted into heat energy, electric energy, chemical energy etc.It is exactly solar water heater that solar energy is converted into a most successful example of heat utilization.Solar water heater has all obtained widely popularization and application because of the characteristic of its excellent heating water in China and the whole world.In general, solar water heater comprises the major parts such as support, water tank, thermal-collecting tube.Long-time extensive use along with solar water heater, people have found a subject matter naturally, be exactly that solar water heater inner (comprising thermal-collecting tube, water tank, ventilating water pipe etc.) produces incrustation scale easily after long-time the use, and it is inner or swim in the hot water to be deposited on water heater.The incrustation scale that is deposited on water heater inside can affect the conduction of mutually the flowing of water in the heat pipe, temperature, and reduce thermal-collecting tube moisture storage capacity, affect the lighting efficiency of thermal-collecting tube, cause water-heater efficiency service life of step-down even reduction water heater gradually.So water heater inside needs the professional that it is carried out periodic cleaning, but this for the user brings many troubles, also increased simultaneously water heater manufacturer's cost.In order to solve the problem of incrustation scale, people once designed many different technical schemes.But what these schemes were really adopted by the water heater manufacturer is very few, and core reasons are summed up and mainly comprise the following aspects: because descale has carried out large change to the design of water heater itself, producer has no attraction for water heater; Cause too complexity is not suitable for real situation, not only complex process but also with high costs; Because of the scale removal effect very faint; Because there are potential hazard in water heater or user, put into the chemical liquid of water heater such as being used for scale removal, can cause potential hazard to human body skin.And often also only in some special or high-end products, use for those effective scale removal schemes, and the scale removal effect also feels embarrassed to mention obviously, thus be difficult to popularize.So when at present domestic large manufacturer was in the face of water heater internal water scale problems, great majority were taked artificial methods of cleaning to the doorstep, although the method is clumsy, but the still relatively high a kind of scheme of cost performance.
In fact, the inner incrusted problem of water heater is not to solve.We are very clearly in fact for the formation of incrustation scale, can analyze first the origin cause of formation of incrustation scale here.Because what use in most water heaters is running water or well water.Take running water as example, when containing more calcium (Ca), magnesium (Mg) salt in the running water, in the process to tap water heating, Ca(HCO
3)
2, Mg(HCO
3)
2Decomposes is CaCO Deng understanding gradually
3, MgCO
3Etc. precipitation, after temperature surpassed 70 ℃, this decomposable process can obviously increase, and these precipitations that produce in static water are deposited on the water heater inwall easily, Here it is incrustation scale.Because the original design thought of water heater is to wish that the As soon as possible Promising Policy user is to the demand of hot water in winter, continuously in the inadequate situation at the sunshine such as overcast and rainy.And then cause new problem: in sunshine sufficient situation, too much heat accumulation is arranged necessarily, make heat collector, water tank etc. be in for a long time the condition of high temperature.This provides sufficient condition for the generation that incrustation scale produces.
We can be clear that the key element of facilitating incrustation scale to form is respectively from the origin cause of formation of incrustation scale: contain a large amount of Ca in (1) water
2+, Mg
2+, HCO
3 -Plasma; (2) high temperature; (3) water is static.For most water heaters, be difficult to the ion concentration in direct control (1) water.But but can control (2) high temperature and static these two factors of (3) water.Particularly high temperature is the most crucial factor that forms incrustation scale when key element (1) possesses, under the hot conditions water static be the promoting factor of assisting.
People also have realized that high temperature to the impact of incrustation scale in fact, so also there is technical scheme to attempt to solve.Chinese patent CN 202195618 U disclose a kind of mechanical electric power apparatus that comprises series of temperature controlling and heat radiation and have controlled water temperature in the water heater to prevent fouling.But thereby this technical scheme is owing to adopt the mechanical electric force control device to cause cost to rise in a large number too much, even also changed significantly solar water heater's internal structure, is difficult to be accepted by manufacturer.In addition, Chinese patent CN201314712Y and the Chinese patent CN 202254443 U flexible abat vent or the cloth that disclose respectively a kind of plane of illumination at solar water heater and increase the TEMP electric control is controlled water temperature.This technical scheme must be considered other factors such as high wind, rainwater corrosion simultaneously, and also adopts too much machine control unit, and also has the additional power demand, and these all cause cost to rise in a large number, also are not suitable with solar water heater manufacturer's demand.
Secondly, for the static problem that also can promote fouling of water, people also once proposed some technical schemes.Chinese patent CN 201083448 Y and Chinese patent CN 201407827Y disclose respectively a kind of thermal-collecting tube that passes through to change solar water heater for connecting cylindrical tube and water inlet in the mode of lower end pipe, and the flowability that has strengthened water in the thermal-collecting tube reaches the purpose of scale removal.But this scheme has all been carried out larger change to existing thermal-collecting tube and water heater integral body, has increased cost and has changed production technology, is not also accepted by the water heater manufacturer.
In addition, it is found that water is magnetized the generation that can effectively prevent incrustation scale, Chinese patent CN2718464Y discloses the method that a kind of device that increases by one section magnetized drinking water at the oral siphon place comes antiscale, but this scheme only allows water obtain magnetization when injecting water tank, and the performance of magnetized drinking water can not keep (generally 6 as a child will disappear in magnetization-with reference to 47 pages of " ability and intelligence " 28 phases in 2009: the physicochemical properties of magnetized drinking water and Mechanisms) for a long time, so antiscaling effect weakens greatly.Chinese patent CN 2911536Y discloses and a kind of magnetizing assembly has been arranged at scheme between thermal-collecting tube and the attemperater, this scheme can allow water formed hot and cold water circulation in the process of rapidly heating pass through magnetization, but when being heated to higher temperature (70-100 degree), water reduces the magnetizer meeting because internal water circulates to slow down, when spending near 100, water temperature inside substantially do not have even internal water circulation and can't be to magnetic water, but high-temperature water produces easily incrustation scale and loses magnetizability at this moment exactly, so cause whole antiscaling effect also not obvious.
So, preventing the generation of incrustation scale, core is to control the temperature of hot water in the water heater and allows the water in the water heater be in the generation that flow regime just can prevent incrustation scale well, allows mobile water constantly further strengthen the ability of scale removal through the energy of magnetization.
