Description

{FILTER FOR HIGH-PRESSURE GAS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-pressure gas filtration apparatus, and more particularly to a filtration apparatus for filtering foreign matters contained in a high-pressure gas.

Generally, water, oil and foreign matter can be included in the high-pressure gas production process.

Moreover, due to corrosion of the bomb (LPG CNG tank) storing the high-pressure gas and various factors, the high-pressure gas inside the bomb is mixed with moisture, oil and foreign matter.

Such contaminated high-pressure gas does not function properly in its application and further contributes to shortening the life of the apparatus using high-pressure gas.

Therefore, a filtration device is provided in the supply line of the high-pressure gas, and the foreign substance contained in the high-pressure gas is filtered through the filtration device.

That is, the high-pressure gas is supplied to the high-pressure gas device in a purified state through the filtration device to fully demonstrate the efficiency of the function and guarantee the service life of the high-pressure gas device.

An example of such a high-pressure gas filtering apparatus is disclosed in Patent Document 1 (hereinafter, referred to as "prior art"), and the configuration thereof will be schematically described below with reference to FIG.

1, a conventional high pressure gas filtration apparatus 1 includes a connection cap 10 having a gas inlet 11 formed therein, a gas outlet 21 connected to the connection cap 10, A filtering filter 30 installed inside the filter housing 20 for filtering foreign matter of high pressure gas and a filter 30 installed between the filter housing 20 and the connection cap 10 A housing sealing ring 40 and a filter seal ring 50 provided between the filter filter 30 and the filter housing 20.

The filter 30 has a gas outlet hole 31 communicating with the gas outlet 21 of the filter housing 20.

However, the conventional high pressure gas filtration apparatus has not disclosed means for discharging the moisture and oil fractions that are filtered during the filtration process to the outside of the filter housing.

Accordingly, the filter housing has to be disassembled and assembled every time in order to discharge moisture and oil, which have accumulated in the filter housing, to the outside, which is troublesome and inconvenient.

In addition, due to the nature of the work, it is difficult to discharge oil and water to the outside unless it is an expert, and in order to do this, it is time consuming to go to the repair shop periodically and the maintenance article is called and paid for.

Further, if the user does not care to replace the filter filter due to carelessness, the filtration efficiency is reduced due to foreign matter, moisture, and oil contained in the filter housing, the degree of contamination of the filter is increased and the filtration efficiency is reduced. Damage will occur.

In addition, damage to the filter housing, such as corrosion, is generated in proportion to the time during which the foreign matter, moisture, and oil remain in the filter housing.

Accordingly, there is a demand for development of a high-pressure gas filtration apparatus which overcomes the above-mentioned problems.
