Description

[0001] The present invention relates to a compressed air storage tank having a gas-liquid separator,

The present invention relates to an air compressor, and more particularly to a compressed air storage tank for storing compressed air. And a gas-liquid separator for lowering the temperature of the compressed air and efficiently separating the mixed moisture, oil, dust, etc. from the compressed air.

Compressed air storage tanks in a typical air compressor system consist of a drainage device for maintaining a constant pressure of compressed air and for removing condensed water. In addition, the air compressor system is equipped with pneumatic cleaning devices such as aftercooler, air tank, filter, air dryer to lower the temperature and remove moisture, oil, dust, etc. to obtain clean compressed air. As the use time of the pneumatic cleaners becomes longer, the performance of the pneumatic cleaners is not constant and the economical loss occurs because the filters must be replaced periodically with the pressure loss.

It is an object of the present invention to overcome the above-described problems of the prior art and to simplify the air compressor system so that compressed air .

A compressed air storage tank having a gas-liquid separator according to an embodiment of the present invention includes a cylindrical body portion having a circular cross-section in the horizontal direction, a cylindrical body portion having a circular cross-section in the downward tangential direction And a compressed air outlet pipe through which the compressed air flows vertically from the upper portion of the body portion, and a compression air outlet pipe through which the compressed air flows, And a liquid outlet pipe through which the separated liquid can be drained at the lower part, and a cooling fin which can drop heat to the outer surface of the body part.

The air compressor system is equipped with pneumatic cleaning devices such as aftercooler, air tank, filter and air dryer to obtain clean compressed air. Oil. Remove dust, etc. By installing one of the pneumatic cleaning devices of the present invention in the present invention, it is possible to eliminate the pressure loss and reduce the economic loss such as periodic filter replacement.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and how to accomplish them, will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. It should be understood, however, that the present invention is not limited to the embodiments disclosed herein but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Embodiments described herein will be described with reference to plan views and cross-sectional views, which are ideal schematics of the present invention. Thus, the shape of the illustrations may be modified by manufacturing techniques and / or tolerances. Accordingly, the embodiments of the present invention are not limited to the specific shapes shown but also include changes in the shapes that are produced according to the manufacturing process.

Unless defined otherwise, all terms (including technical and scientific terms) used herein may be used in a sense that is commonly understood by one of ordinary skill in the art to which this invention belongs. Also, commonly used predefined terms are not ideally or excessively interpreted unless explicitly defined otherwise.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings

FIG. 1 is a perspective view of a compressed air storage tank according to a preferred embodiment of the present invention, FIG. 2 is an air intake geometry flow into a compressed air storage tank, and FIG. 3 is an air flow chart in a compressed air storage tank.

1, 2 and 3, a compressed air storage tank according to a preferred embodiment of the present invention may include a body portion 2, an inlet portion 1, a cooling portion 4 .

The body portion 2 has a general shape of a pressure vessel, and is made of a material having a strength meeting the relevant regulations of the pressure vessel. In this embodiment, the body is formed in the shape of a circular cross section. The body portion 2 also has a hole with an input pipe diameter size? C for tangential engagement with the inlet portion 1, which will be described later. In addition, the body part 2 has a round hemispherical shape at its upper part, and has an outlet 3 for use of compressed air at its upper center part. The body portion 2 also has a cooling portion 4 capable of cooling the heat generated by air compression. In addition, a discharge port (6) having a drain valve (5) is attached to the bottom of the body part (2) so as to discharge separated liquid and solids, ).

The inlet portion 1 is configured to be tangentially connected to the body portion 2 so as to generate a spiral centrifugal force in the flow of air in the body portion 2. [ The inlet (1) is composed of a diameter tube whose diameter changes from? B to? C and is tapered at each angle A to the body part (2) side. The pipe diameter? C is configured to be equal to or smaller than the pipe diameter? E of the compressed air outlet 3 to increase the centrifugal force of the air when it flows into the tank. This is based on the Bernoulli theorem, in which the velocity increases as the fluid flows through the narrow passages and the velocity decreases as it flows through the wide passages. When the air flows into the body portion 2 from the inflow portion 1, the air flows downward at a downward angle D ° so that a centrifugal force is generated in a spiral manner to minimize the collision of the compressed air inside the body portion 2, So that the effect of centrifugal separation can be increased. The downward angle D is away from the centerline of the inlet 1 by F distance in the upward direction as shown in FIG. 2, and the distance of F is sufficient to fall by? C at the incident diameter? C / 2.

The cooling section 4 has cooling fins formed on the outer surface of the body section 2 on a 360 degree crankshaft so that heat generated by air compression is dropped to promote condensation of moisture in the compressed air in the tank .

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
