FIELD OF INVENTION The present invention relates generally to heating systems, and more specifically, to a multi-purpose self-sustained revolving evaporator apparatus (MSRE), for performing a wide range of operations including purification of water, purification of liquids/ or heavy water, salt extraction, separation of solids in liquids, condensing of liquids, heating systems, steam generating, and generating of electricity, etc.

BACKGROUND

Steam generators are, for example, employed for air humidification and generally comprise an evaporation tank, which is partially filled with water. The water is heated and evaporated by means of heating bodies, such as electrodes or electrical resistances and burning of fusel fuels, for example, in which process mineral salts are precipitated which have to be removed from time to time from the evaporation tank by blow down. For this purpose, in order to top up with water and, in some cases, also to monitor the water level by means of a float in a float tank outside the evaporation tank, the latter has at least one water passage opening, which is frequently arranged in the bottom of the evaporation tank. Particularly when water with a very high lime content is employed, a major problem is the formation of lime scale and the rapid closing up of the usually relatively small water passage opening or openings, which often makes cleaning necessary after only a short period. If larger water passage openings are employed, the blow down quantity can scarcely be controlled with respect to time and the danger exists that the water in the evaporation tank will start to oscillate shortly after the blow down.

In order to keep the time intervals between the cleaning operations as large as possible, attempts have been made to provide the water passage openings with devices which prevent rapid blockage. Known arrangements are, for example, the use of screens with a plurality of suitably arranged openings and the pumping of air through the openings from below in order, by this means, to keep water paths free. Also known are openings, which are cleaned by moving parts. The solutions proposed, however, do not permit the maintenance cycles to be increased in a satisfactory manner for all types of water. In view of the problem, with certain types of water, that the water passage openings rapidly form lime scale in the previously known steam generators, the invention is based on the following object. A steam generator is to be created with an evaporation tank with at least one water passage opening which does not form limescale or, at least, forms limescale more slowly than the water passage openings of the previous steam generators.

It is well-known to use humidifying systems which employ steam generators. The boiling of the supply water to generate steam is advantageous because bacteria present in the supply water are killed and minerals present in the supply water tend to remain in the evaporation tank. Thus, the steam fed into the heating, ventilating and air conditioning system is clean and sterile. The supply water in such devices is the usual local supply water which invariably contains insoluble mineral salts, such as calcium carbonate. Thus, over time, deposits of dirt, dust, lime and other minerals accumulate on various interior surfaces of the steam generator, including the heat exchange surfaces and walls of the evaporation tank. This reduces the efficiency of energy transfer from the heat source to the water. Frequent removal of accumulated, adhering, mineral deposits is required. The task of removing accumulated mineral deposits is at least bothersome and it may be quite difficult. Hence there exists a need for an automated self sustained system that is capable of per forming a wide number of tasks such as, but not limited to, steam generating, purification of water and liquids, salt extraction, condensing of liquids, separation of solids in liquids, and generating of electricity etc.

The present multi-purpose self-sustained heat generating revolving evaporator apparatus ( 100) can be attached with conveyor belts or other material transferring means to transfer salt or other solid materials from the evaporating chamber or the high pressure chamber ( 132) in MRE apparatus ( 100) to the outside of the high pressure chamber ( 132).

The different embodiment of the present multi-purpose self-sustained heat generating revolving evaporator apparatus ( 100) discloses different design variations of the apparatus ( 100) by incorporating design elements such as wing type MRE. Some other embodiment of the present multi-purpose self-sustained heat generating revolving evaporator apparatus ( 100) discloses the use of a method known as thin film evaporation, that even enhances the separation of solid substances or salts and the evaporation process to generate pure steam using the present multi-purpose self- sustained heat generating revolving evaporator apparatus ( 100). Further the present multi-purpose self-sustained heat generating revolving evaporator apparatus ( 100) is compact, requires only small surface area to install and operate, easily transportable, can be easily scaled up to increase the capacity depending on the requirement. Further the revolving evaporator ( 172) associated with the present multi-purpose self- sustained heat generating revolving evaporator apparatus ( 100) can be modified such as by expanding the evaporating surface area and changing the rotation speed and direction to modify the output from the present multi-purpose self-sustained heat generating revolving evaporator apparatus ( 100). These modifications can be easily performed depending on the application of the present multi-purpose self-sustained heat generating revolving evaporator apparatus ( 100). Further some embodiment of the present multi-purpose self-sustained heat generating revolving evaporator apparatus ( 100) has a built in heat storage inside the evaporator ( 100) that is capable of storing a desired amount of heat depending on the installed capacity of the heat storage means. In a yet another embodiment, the present multi-purpose self-sustained heat generating revolving evaporator apparatus ( 100) can be installed with more than one heat storage inside the evaporator body (102) that is capable of storing a desired amount of heat depending on the installed capacity of the heat storage means. The installed heat storage inside the evaporator body ( 102) can be of same type of different type depending upon the application, cost and other installation and maintenance requirements. The heat storage means and the heat generating arrangements inside the present multi-purpose self-sustained heat generating revolving evaporator apparatus ( 100) preserves a constant temperature inside the evaporator ( 100).

The different embodiment of the present multi-purpose self-sustained heat generating revolving evaporator apparatus ( 100) discloses different design variations of the apparatus ( 100) by incorporating design elements such as the provisions for providing high-speed hot air using the evaporator apparatus ( 100). The present multi-purpose self-sustained heat generating revolving evaporator apparatus ( 100) is self sustainable, one it is started, without any external power or assistance and is highly efficient for power generation without causing pollution, scarce resource utilization, etc. Moreover the method of generating electricity using the present multi-purpose self-sustained heat generating revolving evaporator apparatus ( 100) is cheaper, cleaner, sustainable, adaptable, scalable, and requires minimum investment, maintenance. The capacity of the present multi-purpose self-sustained heat generating revolving evaporator apparatus ( 100) can be changed by scaling up or down the evaporator apparatus ( 100). The size and shape of the evaporator apparatus ( 100) can be changed by without changing the operating method of the present evaporator apparatus ( 100).
