Description

RECOVERY EQUIPMENT OF OIL MIST

The present invention relates to a vapor recovery apparatus, and more particularly, to a vapor recovery apparatus for separating and recovering organic solvent from a vapor flowing through a cooling chamber by cooling a liquid refrigerant filled in an inner chamber of the apparatus with a cooler, To thereby maximize the liquefaction operation.

As the industrial structure (industrial structure) has become more sophisticated, the emission sources of air pollutants have been diversified and the amount of organic solvents has been increased, so that volatile organic compounds (VOCs) ) Is rapidly increasing.

This increasing oil mist (oil mist) contains toxic pollutants such as benzene, toluene, xylene, and ethylene, which can cause damage to nerves, respiratory, digestive organs and other organs. It also has a negative impact on the atmospheric environment, leading to global warming.

For this reason, the issue of volatile petroleum products used in various workplaces and the problem of the treatment of vapors generated from organic solvents has been designated as a national control target. As a result, amendments and promulgations (2005.11.01) and enforcement (2006.11.02) The use of petroleum-based preservatives made it mandatory to install a recovery device to suppress the emission of vapor. The Air Quality Preservation Act (Law No. 11998) further strengthened regulations on the release of vapor into the atmosphere.

The source of the vapor is largely divided into natural and anthropogenic sources. Natural sources are mainly in the diet. Anthropogenic sources are 46.2% in the paint industry, 34.9% in the automobile industry, about 10% in gas stations and storage facilities, And 10% in other facilities. In particular, when the volatile petroleum products are stored in petrol stations and storage facilities distributed throughout the country, the annual energy loss due to saturation (saturation) of high-concentration vapor in the oil storage tank is 187 Tcal, 26,124 tons were reported.

On the other hand, the source of the oil vapor at the gas station is divided into two stages: the evaporation through the pores of the underground oil storage tank, the unloading of petroleum products such as gasoline and diesel oil from the oil tanker to the underground oil storage tank, . In the case of injecting fuel into an underground oil storage tank, the effect of oil injection on the oil storage tank is influenced by the injection method from the oil tanker to the underground oil storage tank. The reason for fueling the automobile is that the fuel temperature difference between the inside and outside of the fuel tank and the shape and structure of the fuel tank are important factors for discharging the vapor and affect the atmospheric temperature, the amount of loss, and the wind speed.

Accordingly, measures are taken to minimize the amount of VOCs generated through the research and development of treatment technology and treatment equipment (vapor recovery device) that can prevent air pollution caused by vapor from gas stations and storage facilities and solve energy loss problems. This is in urgent need.

On the basis of this technical idea, Korea Patent No. 10-0615072 discloses an organic solvent capable of maximizing the area of contact with the surface of the condenser with steam or air containing an organic solvent, thereby improving the recovery rate of the organic solvent A recovery system has been disclosed.

The organic solvent recovery and dispensing system according to the related art allows selection of a vapor or air supply through the condenser or direct discharge to the atmosphere by the distribution chamber of the shutter system depending on whether or not the organic solvent is contained, The dispersion plate for dispersing the steam or air flow on the front side is installed together with the filter to maximize the area of contact with the surface of the condenser and the steam containing the organic solvent, thereby extending the service life of the filter installed together with the condenser The recovery rate of the organic solvent can be greatly improved.

However, since the rapid cooling operation must be performed to achieve the above-mentioned points, it is required to use a compressor having a large capacity, which is complicated in structure, and thus it takes a lot of manufacturing cost and consumes too much power. come.
