Description

Odor and toxic gas removal device of high voltage electrolysis using liquid ratio

The present invention relates to a device for removing odor and toxic gas of a high voltage electrolysis method using a liquid ratio. In detail, the present invention enables the liquid fertilizer (liquid fertilizer) to be used as a medium for electric discharge and to directly remove odors and toxic gases by applying a high voltage directly to the water, and secondary pollution by removing odors and toxic gases. High voltage electrolysis using liquid fertilizer to improve the completeness of liquid fertilizer because of low maintenance cost by eliminating by-products and eliminating the use of chemicals, and by improving the completeness of liquid fertilizer by naturally adding by-products of decomposed odor and toxic gas to liquid fertilizer It relates to a device for removing odor and toxic gas of the system.

Manure and livestock waste, food waste, and various odors and toxic gases generated in various industrial sites (hereafter referred to as odor generating sources) are the main causes of environmental pollution, causing discomfort and aversion, and even fatal health effects.

Representative malodorous and toxic gases include ammonia (NH³), hydrogen sulfide (H²S), methyl sulfide ((CH³) S), methyl mercaptan (CH³SH), dioxin, formaldehyde, carbon monoxide (CO), volatile organic VOC Volatile Organic Compounds. These odors or toxic gases (hereinafter, odors) may react with each other to act as complex odors or complex toxic gases.

For this reason, a more comprehensive and omni-directional solution is required rather than a separate method for dealing with each odor alone. As a technique for removing such odors, a cleaning method, an adsorption method, a redox method, a microbial treatment method and the like are used, but a satisfactory method in terms of economic efficiency and efficiency has not been developed yet, and a new technology is required.

For reference, liquid fertilizers are well known to mean liquid fertilizers used for soil, hydroponic cultivation, and foliar spray applications. Such liquid fertilizers are provided free of charge to nearby farms or resolved by the creation of lawns. Also, the problem of disposal of liquid fertilizers is an urgent issue due to groundwater contamination, residual odor problems, and residual animal antibiotics in liquid fertilizers.

Recently, a method using plasma is being researched and developed as one of techniques for treating odors in odor generating plants. However, since the initial facility cost is excessive, the problems of economic efficiency and efficiency are not solved. In particular, this method shows a limitation in the treatment of high concentration / high amount of odor due to the small treatment capacity and long reaction time.

The most commonly used odor removal method can be said to be a cleaning method using chemicals. In the chemical cleaning method, each type of malodor is analyzed by analyzing malodors, and a corresponding chemical compound is mixed with water to prepare a chemical liquid, and the chemical liquid is sprayed onto the malodor in a shower method to react the reaction. In this way, the olfactory problem of odor is solved, but a lot of drugs are required, and the cost problem and additional waste water treatment problem are seriously raised.

On the other hand, sewage / wastewater, including leachate produced by various manure and food waste, is discharged through various stages of purification, or by adding microorganisms and fermenting them into liquid fertilizers. During this process, high concentrations / masses of odors are generated. When the cleaning method using chemicals is used to remove the odors, there is a problem of serious secondary pollution, in which a considerable cost is generated and a waste water containing a large amount of chemical compound is generated. .

In addition, although there is an underwater electrolysis method for removing odors, the underwater electrolysis method has high levels of total nitrogen (TN) and total phosphorus (TP) as the electrolysis by-products generated during odor removal are dissolved in water. Does not fit, so a secondary water purification process is required.

Among the technologies developed so far, prior arts such as Korean Patent Application Nos. 10-2009-45210, 10-2007-87377, 10-2011-01311428, 10-2005-0097389, etc. As such, if these technologies are effective, the cost is excessive and the economics are low. On the contrary, if the cost is low and the economics are excellent, the problem of decomposing odor is insufficient.

The present invention has been invented to solve the above problems.

Therefore, the present invention, by applying a high voltage directly to the liquid fertilizer (liquid fertilizer) as the medium of the electrical discharge, it is possible to economically and efficiently remove the odor and toxic gas of the liquid fertilizer, secondary by removal of odor and toxic gas Low maintenance costs due to elimination of contaminant by-products and elimination of chemicals, and odor and toxicity of liquid fertilizers to improve the completeness of liquid fertilizers by naturally adding byproducts of decomposed odors and toxic gases to liquid fertilizers The object is to provide a gas removal device.
