Description

Water separator for compressed air {The water separator}

The present invention relates to a water separator for compressed air for separating the water and other liquid components contained in the compressed air by causing the high-speed centrifugal force to generate a high-speed moving compressed air.

In the present invention, air and moisture are separated by a high-speed centrifugal force generated while the high-speed moving force of the compressed air passes through a plurality of vortex induction plates without the filter element itself in removing the water of the compressed air. The compressed water is bulked together during the rotational movement of the particles, is transported to the bottom by gravity to be received by the drain unit, the compressed air for automatically discharged through the drain valve as described above It relates to a water separator.

Conventional compressed air moisture separators are commonly referred to as mist separators or demisters, and use fine porous filter elements to remove moisture contained in compressed air, and compressed air filters When passing through the element, water droplets are trapped by the micro-holes of the filter element and cannot pass through. Although the water separator for the filter element type compressed air has a water removal effect, there are many problems in the water removal performance and maintenance in principle of using the filter element.

That is, the filter element inevitably causes clogging due to propagation of dust or bacteria in principle composed of a microporous structure such as a nonwoven fabric, a plastic sintered body, and a metal sintered body. Therefore, after the filter element is exchanged, it functions normally for a certain period of time, but clogging of the pores proceeds as the time of use increases, and as the blockage progresses, the cross-sectional area through which air can pass decreases, making compressed air difficult to pass. . That is, the pressure loss increases. This results in waste of energy and the outlet pressure drops below the required pressure. Therefore, the pressure difference between the front and rear ends of the filter element should be replaced.

That is, the filter element must be replaced regularly as a consumable, and it is difficult to pinpoint the degree of clogging, that is, the more accurate replacement time, which has various problems. In addition, finer pore filter elements are used as high cleanliness is required. The trouble caused by clogging is more severe as the filter elements are finer.

Or, in order to know the exact replacement time, pressure gauges are installed at the front and rear ends of the filter element to grasp the pressure difference, resulting in an increase in equipment cost and additional maintenance.

In order to solve the problems of the conventional conventional compressed air separator, the Korean Utility Model Application No. 2003-23530 (hereinafter referred to as “Prior Art 1”) discloses and uses a “compressed air separator”. The configuration is as follows.

The water separator for compressed air of the prior art 1 is formed by dividing the inner space of the cylindrical housing at equal angles on the outer circumferential part, and having a large inclination nozzle with a large inclination angle with respect to the vertical axis. It is divided into two upper and lower pressure chambers consisting of the lower pressure chamber of the space.

In addition, the compressed air containing moisture is first introduced into the upper pressure chamber, and then the plurality of inclined nozzles formed on the shield plate are inclined and discharged in the tangential direction of the lower pressure chamber having a relatively low pressure so that the rotation center is constant and horizontal. Generates high speed vortex rotation close to

In addition, the water contained in the compressed air is rotated to the outside by the centrifugal force by vortex rotation, so it is separated by friction with the inner wall.

Configured to drain the group.

The moisture separator for compressed air of the related art 1 stays in the upper pressure chamber of the upper body for a while and moves to the lower pressure chamber through the inclined nozzle formed on the outer circumferential surface of the shielding plate.

At this time, the compressed air of the upper pressure chamber is moved through the inclined inclined nozzle to generate a centrifugal force that is bounced outward and hit the inner surface of the outer cylinder.

As such, the compressed air is rotated by the centrifugal force and hits the inner surface of the outer cylinder to separate moisture contained in the compressed air.

The compressed air separated from the water is discharged to the outlet through a pipe fixed to the lower pressure chamber.

However, the above-described prior art 1 has a problem in that the water of the drain unit is scattered to the second pressure chamber by internal pressure difference and vibration when the water filled in the drain unit moves the compressed air, and the scattered water is discharged to the compressed air. There was a problem in that the compressed air efficiency is lowered to be discharged in a state containing.

In addition, in order to solve the problems of the conventional conventional compressed air separator, the Korean Patent Application No. 2006-0105773 (hereinafter referred to as "Prior Art 2") is disclosed and used "dehumidifier for compressed air" The configuration is as follows.

A through hole is formed at one side of the pipe to allow compressed air to pass through, and a second through hole is formed at the center of the pipe in the same way as the first plate, and a second plate is formed to have an inclined groove adjacent to the outer circumferential surface thereof. An insertion groove is formed on one surface of the first and second partitions so as to be fitted into the pipe, and a plurality of inclined grooves are formed on the outer circumferential surface of the first and second partitions.

The conventional technology 2 as described above solves the problem that the water of the sump is scattered to the second pressure chamber by the internal pressure difference and the vibration when the water filled in the sump moves the compressed air by additionally configuring the second plate, and the scattered water is discharged. Solve the problem that the compressed air is discharged in a state containing the compressed air is lowered.

However, according to the prior art 2 as described above, the water of the centrifugal force generated by the centrifugal force is separated from the lower pressure and stored in the water collecting tank, so that the water does not move to the water collecting tank while the air is discharged through the pipe. It is true that there is a problem in that it is discharged with air through a pipe instead of exhausting clean air.

Therefore, the present invention has been made to solve the above problems, by installing a plurality of vortex induction plate to increase the centrifugal force by generating a strong vortex in the air to separate the moisture of the air more completely, as well as other liquid components also separated The purpose is to provide a moisture separator for compressed air that discharges only clean air.

In addition, the problem that the moisture stored in the drain unit is scattered to the pressure chamber by the internal pressure difference and vibration when moving the compressed air is also solved, it is discharged in the state contained in the compressed air that the scattered water is discharged, the compressed air efficiency is not reduced. The purpose is to provide a moisture separator for compressed air that can be prevented.
