Description

Device for removing fine dust and preventing white smoke {APPARATUS FOR REMOVING FINE DUST AND PREVENTING WHITE PLUME PHENOMENON}

The present invention relates to a device for removing fine dust and preventing white smoke, and more particularly, it is installed in a chimney of a process for emitting white smoke and harmful gases such as boilers, melting furnaces and incinerators to reduce or prevent white smoke, and to reduce fine dust and harmful gases It relates to a device for removing fine dust and preventing white smoke that can remove pollutants including.

This invention is the result of a research carried out as a technology development project for fine dust reduction practical use supported by the Small and Medium Business Technology Information Agency (task number: S2929866, research project name: wet electric dust collector for fine dust removal).

As a gas is saturated, the amount of water vapor it can hold changes with temperature. The higher the temperature, the greater the amount of water vapor it can hold. Therefore, if the temperature of the gas or air is lowered, condensation occurs in which a part of the water vapor is liquefied.

When air pollutants contained in high-temperature combustion gas are treated with a wet electrostatic precipitator or wet cleaning device in the process of emitting white smoke and harmful gases from boilers, melting furnaces and incinerators, etc. The temperature of the gas is about 60~80℃, and since the washing water evaporates at this time, the moisture content in the gas almost reaches saturation at the exhaust gas temperature.

In this state, when exhaust gas is discharged to the chimney, a difference in the amount of saturated water vapor occurs as much as the temperature difference with the atmosphere, and the supersaturated water is liquefied. Due to this dew condensation, the moisture in the gas becomes particles into fine water droplets, resulting in a white smoke phenomenon.

When white smoke occurs, it causes visual pollution problems and visual disturbances in the landscape, and fine particulate pollutants such as moisture, sulfate, and unburned residue are often discharged together.

In other words, there is no legal regulation on the white smoke phenomenon, but the reasons for trying to eliminate the white smoke phenomenon in general are as follows.

1) Prevents corrosion of the inside of the chimney by reacting moisture and oxides in the exhaust gas,

2) In the case of the heating type, the exhaust gas temperature is raised to improve the ventilation power of the exhaust gas, thereby facilitating the air diffusion of the exhaust gas,

3) Secure visibility when aircraft take off and land near the aerodrome;

4) to prevent damage to the aesthetics of cities and tourist destinations;

5) In the case of white lead discharged from the scrubber, acidic substances that have not been completely vaporized and water vapor in droplet form, which is a by-product of neutralization reaction, does not diffuse and falls down the chimney to prevent it from contacting nearby vehicles, buildings, and human bodies to affect the drug. is to do

Currently, methods attempted to prevent white smoke include a method of heating exhaust gas, a method of mixing external air and exhaust gas, and a method of installing a condenser outside. However, among these methods, the method of heating exhaust gas is not economical in terms of fuel cost and facility maintenance cost, and the method of mixing external air and exhaust gas requires a large amount of air. have.

In addition, as disclosed in Korean Utility Model Registration No. 20-0210607, the method of installing the condenser outside also has a problem in that the installation is complicated and requires a lot of installation space, so that it takes a lot of cost.

In addition, the conventional white smoke reduction apparatus has a limitation limited only to the function of reducing the white smoke even though it is a relatively expensive facility.
