KR-20260067633-A - Exhaust gas dust removal device using cyclone and vortex tube

Abstract

The present invention is a device for more efficiently removing exhaust gas dust using a cyclone and a vortex tube, and aims to effectively remove exhaust gas dust by utilizing fine water particles generated by the condensation effect when high-temperature humid exhaust gas and low-temperature air generated in the vortex tube are mixed together.

1.

Description

Exhaust gas dust removal device using cyclone and vortex tube Exhaust gas dust removal device using cyclone and vortex tube The present invention relates to a system for reducing pollutants and dust in exhaust gases generated in ships and industrial processes, and more specifically, to a device that utilizes a cyclone and a vortex tube to simplify the structure, thereby saving manufacturing costs, reduce maintenance costs with minimal power consumption, and efficiently protect the environment. Fine dust, resulting from pollutants and dust in exhaust gases, has a small diameter and can penetrate deep into the human body through the respiratory system, which can cause various health problems such as respiratory diseases, cardiovascular diseases, and allergies; therefore, reducing fine dust concentration is an essential task for health protection. Pollutants and dust emitted from ships or industrial processes are major causes of air pollution, and these pollutants include nitrogen oxides (NOx), sulfur oxides (SOx), and volatile organic compounds (VOCs), which react in the atmosphere to form secondary pollutants and become a factor in increasing the concentration of fine dust. Environmental regulations in various countries are gradually becoming stricter, and industries must meet legal emission standards. In particular, as permissible air pollutant emission standards continue to be tightened to reduce high concentrations of fine dust and pollutants, the development of technologies to respond to these regulations is essential. Technologies for removing pollutants from exhaust gases are important in terms of economic feasibility, efficiency, and sustainability; while conventional chemical treatment methods are costly and carry the risk of additional pollution from chemical residues, pollutant removal through physical and mechanical methods is relatively environmentally friendly. Physical treatment methods utilizing cyclones and vortex tubes collect and remove pollutants using rotational force, centrifugal force, and gravity, without the use of chemical absorbents. This approach offers the advantage of continuous and low-cost operation, making it a viable option for reducing pollutants from a long-term perspective. FIG. 1 is an angled view showing the shape of a vortex tube (2) combined with a cyclone (1), and the vortex tube (2) is combined with the upper side of the cylinder of the cyclone (1). The cyclone (1) is composed of an inlet section (1a) into which contaminated exhaust gas is introduced, a collection section (1b) into which contaminants are collected, and an outlet section (1c) into which purified gas is discharged to the outside. The inlet section (1a) is configured so that exhaust gas is introduced in a tangential direction to the upper cylindrical structure of the cyclone (1), thereby allowing the exhaust gas to swirl inside the cyclone (1). The bultex tube (2) is composed of an inlet (2a) through which compressed air is supplied, a low-temperature outlet (2b) through which low-temperature air is discharged, and a high-temperature outlet (2c) through which high-temperature air is discharged. The low-temperature outlet (2b) is connected to the upper part of the cylinder of the cyclone (1) and is attached so as to maintain a certain angle so that the fluid can rotate sufficiently inside the cyclone (1) when connected. Next, embodiments of the present invention will be described with reference to the drawings. In this process, the thickness of lines or the size of components depicted in the drawings may be exaggerated for clarity and convenience of explanation. Furthermore, the terms described below are defined considering their functions in the present invention, and these may vary depending on the intention or convention of the user or operator. Therefore, the definitions of these terms should be based on the content throughout this specification. High-temperature humid exhaust gas containing dust introduced into the inlet (1a) of the cyclone (1) meets and swirls with low-temperature air discharged through the low-temperature outlet (2b) of the vortex tube (2) inside the upper cylinder of the cyclone (1) and mixes with each other. The high-temperature humid exhaust gas meets the low-temperature air and condenses to create fine water particles in the form of fog (mist). The generated water particles become heavier as they adsorb to each other through collision with the dust of the exhaust gas. The dust adsorbed to the water particles descends due to gravity and accumulates, which is then collected in the accumulation section (1b). The purified gas is discharged to the outside through the outlet (1c) of the cyclone.
