CORROSION-FREE ELECTRONIC DESCALING TECHNOLOGY

WO/1997/014654

A method for minimizing localized corrosion of fluid containers that occurs as a consequence of most non-chemical procedures for removing scale deposits is described. It counteracts the unavoidable side-effect of the lowering of the local pH in the vicinity of the bubbles of CO2 that are generated during an electromagnetically-induced controlled precipitation procedure (17). The method is a simple and facile procedure for curbing the localized corrosion occurring as a result of most nonchemical procedures for removing scales. The method is desirably performed by an induction coil (20) wrapped around a fluid container such as a pipe encrusted with scale through which hard water is flowing (18). A pulsing electrical current (22A) is successively applied, a transitory induced electric current is generated in the solution, and scale encrusted on the fluid container dissolves in the solution. When the pulsing is stopped, the induced electric current in the solution ceases and so the scale stops dissolving, allowing a protective layer of scale to form over potential points of corrosion. Optionally permanent magnets may be used in the process, alone or with an induction coil.

The hardness of water is caused by the existence of high amounts of calcium and magnesium ions dissolved in water. When water, which enjoys a strong dissolving property, passes over stone substrates such as limestone, CaCO3, or dolomite, CaMg (CO3)2, these minerals gradually enter the water and raise the water hardness. Moreover, increasing the temperature in water with high hardness causes the formation of sediment. This is among the most critical dilemmas and concerns, particularly in the equipment associated with heating facilities in homes. Sediment formation in equipment and piping systems leads to a reduction of their efficiency, damages, and ultimately enhancement in the expenses of repair and replacement. One of the problems present in the buildings is the absorption of calcium and magnesium ions by thermal facilities, particularly in the place of fluid temperature increase, which has been overcome by using a brushless pump with a magnetic spiral axis and separating the selective filter chamber without reducing the performance efficiency. The above-mentioned invention is related to the magnetic descaling device of the fluid of thermal facilities, which carries out descaling using a brushless pump with a direct magnetic core. Furthermore, it enjoys the capability of selective conduction on the filter.

Although the hardness of water does not cause serious harm to human health, the apparent problems created by water with high hardness and also the problems it generates for people and households in connection with water and energy consumption is a matter that has always attracted the attention of consumers and experts in this area to prevent descaling of high hardness water. The water hardness causes sediment formation in the water piping system and the devices available in the house through which the water passes, and thus, leads to reducing the efficiency of the water supply system. Moreover, as sanitary detergents hardly foam in contact with water with high hardness and have less cleaning ability, consuming these detergents during bathing or washing clothes and dishes in homes with high water hardness also enhances and will burden considerable expenses for the household over time.

The hardness of water is caused by the existence of high amounts of calcium and magnesium ions dissolved in water. When water, which has a strong dissolving property, passes over stone substrates such as limestone, CaCO3, or dolomite, CaMg (CO3)2, these minerals gradually enter the water and raise the water hardness. Hence, the hardness of well water is typically higher than that of surface water. The sediment resulting from the hardness of water is indeed insoluble calcium and magnesium compounds such as calcium carbonate (CaCO3) and magnesium silicate (MgO3Si). The solubility of these compounds in water lowers with increasing temperature and they are deposited on the surfaces. Among the problems present in the buildings is the absorption of calcium and magnesium ions by thermal facilities, particularly in the place of fluid temperature increase, which has been overcome by using a brushless pump with a magnetic spiral axis and separating the selective filter chamber without reducing the performance efficiency.

Solution of problem

To overcome this problem, the magnetic and electromagnetic types fabricated in the existing samples, despite enjoying multiple advantages, also have weaknesses, one of which is less impact because of space. Utilizing the magnetic spiral shaft (6) and the magnetic conductor feeder (8), the previous problems were diminished in this invention. To minimize the size of the pump (1) and enhance its efficiency while increasing its safety of the pump (1), it is built of inner (3) and outer (2) parts. In the inner part (3), the pump transmission pipe (4), the end ball (5), the magnetic spiral (6), the start ball (7), the magnetic feeder (8), and the internal spike (9) are positioned. Then, the magnetic actuator (10) is recessed on the transfer tube (4) in a sliding manner and fixed in its place by the external spike (11). The pump transmission pipe (4) is composed of the following sections. The beginning thread (12) and the end thread (16) are in the reverse direction of each other, allowing the simultaneous opening or closing by the rotation of the pipe (4). Taking into account the requirement for high force for opening or closing the sealed pipes in the connections on the pump pipe (4), a hexagonal outer section is designed until the location of the wrench (15) is available. Besides, the geometrical shape of the location (13) of the coils in the same direction prevents reverse rotation when applying force to the spiral shaft (6). At the end of the placement of the outer section (2) on the pump pipe (4), there is an annular groove (14) for the outer stud. Moreover, the movement limiter (17) at the end of the pipe with the least amount of resistance to the fluid passage is designed, and it is slightly larger than the 6-ear cross section on the external surface of the pipe until limiting the outer section (2) is also established (2). By scrutinizing in the cut generated from the pipe, more details in the grooves created are observed. The groove (19) is exploited for the placement of the feeder plus the magnetic shape (8) to avoid its unwanted rotation. In the section approaching the beginning of the pump pipe (4), a groove parallel to the edge of the pipe is generated, which is the closing place of the internal spike (20). The placement of the external spike (17) is also deformed in the external surface (18) to be proper for closing and holding. The magnetic spiral that consists of a metal axis (21) and the surface of the magnetic metal spiral (22) spread over it is covered by a thin layer of Teflon plastic so as not to absorb magnesium and calcium ions. Two ends of the shaft exist in the recess (depression) of the hemisphere, which is the placement of anti-wear balls. The magnetic feeder (8) is constructed of plus (+) shaped blades (23) of strength connection base (25) and the retaining hole (24), which is extended along the feeder. Besides aligning the suspended magnetic particles before entering the coil inside the boiler, this feeder has the duty of keeping the parts in place. This part is easily replaceable and rechargeable. To hold the magnetic feeder (8), the internal spike (9) is directed from the side of the conical projection (28) to the feeder side (8) inside the pipe, and the lateral protrusions (27) are locked in place after reaching their places (20) inside the pipe with a little rotation. Connecting the cone (28) to the body of the spike is carried out by four blades (26), which are located in the direction of the feeder blades (8) so that they have the minimum resistance against the water fluid. The outer section (2) is made of a shell and lid and electromagnets. The plastic shell consists of an outer cylindrical shell (29) and a plastic bottom (31) and a hexagonal inner surface (30), on which magnetic magnets are mounted on the inner surface and its distance from the outer surface (29). These magnets are responsible for generating the magnetic field needed for the spiral shaft rotation. The magnets contain an electric coil (33) which is placed around the iron core (32). There are a total of six coils that have a common end in the electrical connection and are parallel to each other two by two at four electrical input ends. These inputs are connected to positive-type bipolar transistors (37), which are three in number and are placed on the metal cover for heat transfer to the fluid. The cover (38) is slightly thicker in the inner part (36), which sinks into the shell body. The electronic circuit (35), which is typically made of aluminum, and the transistors (37) positioned on it extend to the hexagonal protrusion in the inner part of the cover (34). The hexagonal protrusion (34) touches the pump pipe body. The connection of the electronic circuit (35) to the control equipment takes place via the connector (39).

The external spike (11) has two surfaces on one side. It contains an upper surface (40), in which the surface depressions (41) are created. To build this spike, some slightly flexible materials, like ABS plastic, are utilized. After being placed in the groove (17), this spike puts the depressions (41) in front of the protrusions (18) with a little rotation and prevents the rotation and exit of the outer chamber.

The filter device (42) is designed so that the disassembling and cleaning of the filter or its replacement is conducted in the simplest possible way. The device is constituted of a filter shell (45), a metal filter (46), a spring to keep pressure and distance (47), a water diverter (48), and a cover (50). The filter is composed of three parts: the outer non-porous layer (54), the inner mesh layer (55), and the handle and spring conductor (53). The pore size of the filter is smaller than the suspended particles and it should be cleaned or replaced with any amount of work relying on the hardness of the water. The cover (50) has threads (49), which are closed and opened in the inner threads (51). Merely by having an Allen key, the cover (50) can be easily opened. When the spring (47) comes out, the conductor part of the spring (53) will be available, and the filter can be taken out. There is a connected washer (52) at the end of the spring, which creates ease of rotation.

The electronic circuit of the controller embraces the processor (56), the connection connector (57), and the input voltage regulator (58), where the amount of fluid passing and the errors are visible by displaying the information on the screen (60). The display of the presence of input voltage is seen by LED (59) and the health and performance of the outputs towards the engine in LEDs (62). Taking into consideration the weakness of the outputs, an operational amplifier (61) was exploited to stimulate the transistors. With regard to a higher pressure during the filter operation (42), a solenoid valve (63) is placed in the path of the transmission pipe (64) for reducing the pressure and wasted energy, where this valve will block the direct path when it requires to be separated by the filter (42), and the water will be directed in the filter path.

Advantage effects of invention

Using magnetic and electromagnetic properties of electric coils and fixed and moving magnetic cores leads to the higher orientation of magnesium and calcium ions and is accompanied by a substantial enhancement of efficiency. Utilizing Teflon coating in different parts of sediment absorption is minimized, and the possibility to control the flow rate of fluid by the frequency of the brushless pump motor is easily provided. Removal of the gearbox and direct application of force to the rotating spiral axis has brought increased efficiency and reduced breakdowns. Besides, the design related to the section filter and pump is so that each part can be completely accessed, disassembled, reassembled, and serviced only by having a non-specialist wrench, which is so favorable for repairmen. Furthermore, descaling will be carried out with the entry of new fluid using an electric valve for selective conduction on the filter or the free path without a dramatic reduction in efficiency, and then it will be directed in the free path, which omits the requirement for increasing the pressure in the operating state.
