Description

Large scale high density plasma genera-ting device

The present invention utilizes high-density plasma discharge to provide various gases such as NOx, SOx, CO, unburned hydrocarbon (HC), soot, dust, general industrial gas, and various wastewater and wastewater contained in the incinerator exhaust gas. The present invention relates to a high-capacity high density plasma generating apparatus capable of effectively purifying and removing the gas. Specifically, the body is composed of an outer cylinder in which a plurality of anode rods are installed, a cathode tube in which a plurality of cathode tubes are installed, and an insulating material surrounding the outer cylinder. ㆍ The lower body connects the funnel-shaped upper body with the lower body with an insulating material, and the upper body has an air filter and an intake port, and the lower body has a high-density high-density plasma generated by the intake pump (or intake fan) or venturi tube structure. Naturally vented exhaust vents were formed to allow applications in many industries.

In general, plasma may be generated by flowing a voltage of several thousand to tens of thousands of volts and a current of several mA to several A between a cathode and an anode punched in a planar conductor plate. The plasma thus generated is composed of ion radical electrons and is called a fourth state of matter following a gas, a solid and a liquid. At this time, when a corona discharge occurs between the positive electrode and the negative electrode, an anion is mainly generated (generated), and when a spark discharge occurs, ozone (O ₃ ) is mainly generated.

Such plasma can be used for the purification of exhaust gas from diesel vehicle exhaust gas purification apparatus (Patent No. 10-0188234), air purifier, incinerator, and high concentration industrial wastewater, livestock wastewater, and landfill leachate. Can be used.

On the other hand, Patent No. 10-0188234 registered by the present applicant (inventor) on January 11, 1999 "The exhaust gas purification device of a diesel vehicle using plasma discharge" has a conductive end face inside the tubular negative electrode. Discharge electrode is formed by combining the cut rod-shaped positive electrode, which leads to dissipation and dissipation of discharge charges. Therefore, the discharge electrode has a short lifetime and low discharge efficiency. There was also a problem falling.

In addition, the water treatment apparatus used for the purification of high concentration industrial wastewater, livestock wastewater, landfill leachate, etc. also had low efficiency and short lifespan.

In addition, when the plasma generator is configured in a multi-layered structure, plasma generated from an upper layer plate collides with a lower layer plate, and radicals are destroyed, and plasma loses activity. Thus, plasma generation efficiency is greatly reduced.

Therefore, in the present invention, the large-capacity, high-density plasma generated by the discharge is naturally discharged without colliding, thereby greatly improving the efficiency to purify these polluted gases and wastewater, and at the same time, the dioxins and the fines contained in the incinerator exhaust gas. An object of the present invention is to provide a high-capacity, high-density plasma generator capable of purifying and treating combustion volatile organic compounds (VOC) and pollutants in wastewater and wastewater.

In addition, an object of the present invention is to provide a high-capacity high-density plasma by discharging the high-density plasma generated by numerous discharge cells composed of a cathode tube and an anode rod at close intervals.

In addition, a high-density high-density plasma generator is configured to be slim (applicable) to be applied to various industrial fields.

In addition, in the case of a slim type plasma generating apparatus, one or more high density plasma generating apparatuses are connected in series, in parallel, or in series and in parallel to provide a high volume of high density plasma.

In addition, when the present invention is used in a place where a high temperature occurs, it is recommended to use a ceramic-based insulating material having excellent heat resistance, and when used in a place where a low temperature or room temperature is generated, the heat resistance is somewhat lower, such as synthetic resins, Teflon, silicon, and bakelite. Use insulation material.

In order to achieve the above object, the conductive positive electrode plate and the conductive negative electrode plate to which the discharge power is supplied are faced to the inner space of the insulated case in which the inlet and the exhaust port are formed. The anode plate is fixed to the cathode plate at a position corresponding to the cathode tube 1: 1, and then a high density plasma is generated by the cathode cell and the cathode tube which are discharge cells by combining the cathode tube and the anode rod having the discharge space. Plasma is joined through an exhaust path formed between the cathode tube and the casing to be enlarged, and then discharged to the exhaust port. Between the anode plate and the cathode plate, a channel is formed to be connected to the intake port, so Radiation is prevented from hitting or colliding through the cathode tube, exhaust passage and exhaust vent The destruction of the knife or the deactivation of the plasma is prevented to generate a high-density plasma.

In addition, in the present invention, the positive electrode plate to which the positive electrode rod is fixed and the negative electrode plate to which the negative electrode tube is fixed may be variously configured in a flat plate shape, a cylindrical shape, a square shape, or a rectangular shape, and air is introduced into the discharge space by installing a detachable / attachable air filter at the inlet port. Ensure that the plasma is clean and that good quality plasma is obtained.

In the present invention, the discharge cells installed in a 1: 1 correspondence on the positive electrode plate and the negative electrode plate are installed at numerous intervals at close intervals, and dioxins, unburned volatile organic compounds (VOC) contained in exhaust gas incinerators, and various contaminants in dust and wastewater. To effectively oxidatively decompose using a large-capacity high density plasma discharge flame.

In the present invention, the positive electrode plate to which the positive electrode rod is fixed and the negative electrode plate to which the negative electrode tube is fixed may be formed in a flat plate shape, a cylindrical shape, a square shape, or a rectangular shape.

In addition, in the case of the slim type, the positive plate and the negative plate are configured in a flat plate instead of the inner and outer cylinders, but are installed so as to face each other in parallel, and the positive electrode and the negative electrode tube are installed at a ratio of 1: 1 to obtain a high density of plasma.

Plasma discharge electrode of the present invention is formed of a pointed needle with a metal or metal alloy excellent in acid resistance, wear resistance and electrical conductivity to greatly increase the plasma generation efficiency.

The plasma purification apparatus of the present invention generates a high voltage of 3,000V to 25,000V with a high voltage generator (HV), and then supplies them to a plurality of discharge electrodes to generate a large amount of high-density plasma by corona discharge. It is applied to the exhaust gas or waste water purification device so that polluted gas and waste water can be purified.

At a high voltage of 3,000 V to 25,000 V, the blue-powered plasma is generated and the exhaust gas purification efficiency is further increased. The generated plasma is discharged with a long length and great force by the tubular cathode tube and the rod-shaped anode rod structure, so a high-density plasma is generated. Therefore, the purification efficiency of exhaust gas, soot, or waste water is very excellent. When installed, there is an advantage that can increase the purification efficiency to the maximum from the initial start.

In addition, in the present invention, by installing two or more large-capacity high-density plasma generators in series, in parallel, or in series / parallel mixing type, it is possible to maximize the purification efficiency of the exhaust gas or wastewater.

Plasma discharge electrodes are installed in plural densities with high density to minimize the discharge resistance of the exhaust gas discharged to the maximum, so that there is no increase in engine load and stroke due to discharge pressure.In the case of wastewater treatment equipment, high density anions are supplied in large quantities. To maximize the purification efficiency.
