FIELD OF INVENTION

Embodiments of a present disclosure relate to performing surface treatment of entities using corona discharge, and more particularly to a system and method of applying the corona discharge for the surface treatment of an entity.

BACKGROUND

Corona discharge is an electrical discharge caused by the ionization of a fluid such as air surrounding a conductor carrying a high voltage. Similarly, plasma discharge is generated in a vacuum or in presence of a gas such as, but not limited to, Helium, Argon, Hydrogen, Nitrogen, or the like. Plasma is the most active state of matter. The corona discharge or the plasma discharge are used in many industrial applications for surface treatment of various materials such as wool, fiber, textile, spices, paper, polyester, pulses, grains, and the like. The surface treatment could be etching, deposition, sterilization, fumigation, functionalization, surface modification, surface cleaning, surface heating, and the like of the corresponding materials. There is a plurality of approaches including a system that uses the corona discharge or the plasma discharge for the surface treatment of the materials.

However, such approaches are associated with multiple disadvantages such as the presence of air gap between the electrodes and the dielectric material used in the system eventually reduces the life of the electrodes, thereby making such approaches less reliable. Also, as the corona discharge is uncontrolled, there is a possibility of causing harm or destruction to the materials which are undergoing the surface treatment, thereby making the system risky. Hence, there is a need for an improved system and method of applying corona discharge for surface treatment of an entity which addresses the aforementioned issues.

The shaft (40) is electrically coupled to at least one electric generator (50). The at least one electric generator (50) is configured to generate the corona discharge between the at least one pair of electrodes (30) at a predefined frequency of a predefined frequency range.

The input processing module (160) may be configured to identify the entity based on the one or more parameters received by the input module (140). Basically, in an embodiment, the entity may be associated with one or more standard parameters based on which the entity can be identified. The corresponding one or more standard parameters may be stored in a database (170) of the system (10). In one embodiment, the database (170) may include a local database or a cloud database. Thus, upon receiving the one or more parameters by the input module (140), the input processing module (160) compares the corresponding one or more parameters with the one or more standard parameters in order to identify the corresponding entity.

The input processing module (160) may also be configured to measure one or more properties associated with the corona discharge via one or more measuring devices (180), upon identifying the entity. In one embodiment, the one or more properties of the corona discharge may include at least one of a temperature, a pressure, a current, a voltage, and the like of the corona discharge. In an embodiment, the one or more measuring devices (180) may be placed electrically coupled to the corona discharge chamber (20) such that the one or more measuring devices (180) are able to measure the one or more properties associated with the corona discharge generated within the corona discharge chamber (20), and not causing any harm or damage to the corresponding one or more measuring devices (180). In one exemplary embodiment, the one or more measuring devices (180) may include at least one of a temperature sensor, a pressure sensor, a current measuring device, a voltage measuring device, and the like.

The input processing module (160) may also be configured to extract historic data associated with the corresponding entity based on the identification of the entity upon measuring the one or more properties associated with the corona discharge.

In one embodiment, the entity may be associated with the historic data such as, but not limited to, a threshold temperature, a threshold pressure, a threshold voltage, a threshold current, and the like which the entity can withstand. Thus, when the one or more properties of the corona discharge measured by the input processing module (160) are not in accordance with the historic data associated with the corresponding entity, then there is a possibility of causing a destruction or harm to the entity when the corresponding entity is exposed to the corona discharge the corresponding one or more properties. Thus, in such a case, the one or more properties on the corona discharge may have to be changed in order to establish an ideal environment within the corona discharge chamber (20) for the surface treatment of the entity without causing any harm to the corresponding entity. Further, the one or more properties of the corona discharge may be changed by changing a frequency at which the electric generator (50) is generating the corona discharge between the at least one pair of electrodes (30). Thus, the processing subsystem (130) may also include a controlling module (190) operatively coupled to the input processing module (160). The controlling module (190) may be configured to generate a control signal to be transmitted to the electric generator (50) to control the predefined frequency of the predefined frequency range, based on the one or more properties measured and the historic data extracted by the input processing module (160). In one embodiment, the electric generator (50) in general may include at least one of a power supply unit, a voltage regulator, a voltage converter, a plurality of resistors, a rectifier, a filter, and the like.

Basically, in an embodiment, the controlling module (190) may compare the one or more properties of the corona discharge with the historic data associated with the entity.

Thus, in one embodiment, the frequency controller (200) may change the predefined frequency within the predefined frequency range such that the entity may be able to withstand the one or more properties of the corona discharge upon changing the predefined frequency of the predefined frequency range. In such embodiment, the frequency controller (200) may change the predefined frequency within the predefined frequency range when the one or more properties of the corona discharge are not in accordance with the historic data associated with the entity. In another embodiment, the frequency controller (200) may maintain the predefined frequency of the predefined frequency range same when the one or more properties of the corona discharge are in accordance with the historic data associated with the entity.
