As shown in FIG. 2, the separating compressor according to the preferred embodiment of the present invention includes a first compartment 100 and a first compartment provided with a hydraulic pressure generator 110 that generates power so that the fluid can be compressed. It is spaced apart from (100), the second compartment 200 is provided with a diaphragm compressor 210 for compressing the fluid is formed to communicate with each of the first compartment 100 and the second compartment 200, the hydraulic pressure is generated It includes a hydraulic pipe 300 for transmitting the power generated through the device 110 to the diaphragm compressor 210, the first compartment 100 and the second compartment 200 is separated and spaced apart, the diaphragm Even if the fluid inside the compressor 210 leaks, it prevents the leaked fluid from flowing into the second compartment 200.

First, the first compartment 100 is provided. The first compartment 100 is provided with an empty space therein, and an empty space inside the first compartment 100 is provided with the hydraulic pressure generating device 110. In addition, the first compartment 100 is spaced apart from the second compartment 200, so that even if the fluid inside the diaphragm compressor 210 leaks, the leaked fluid does not flow to the second compartment 200. Explosion-proof design can be omitted. That is, by reducing the thickness of the wall of the first compartment 100, etc., it is possible to reduce the cost of installing the separate compressor system of the present invention.

Next, the second compartment 200 is provided. An empty space is formed in the second compartment 200, and the diaphragm compressor 210 is provided in the empty space inside the second compartment 200. Unlike the first compartment 100, the second compartment 200 is designed to be explosion-proof in case the fluid inside the diaphragm compressor 210 leaks. As a result, in the installation of the separable compressor system of the present invention, the second compartment 200 is designed to be explosion-proof, and the first compartment 100 is designed to reduce the installation cost by omitting the explosion-proof design.

Next, the diaphragm compressor 210 is provided. The diaphragm compressor 210 serves to compress the fluid. In more detail, the diaphragm compressor 210 is provided in plural, and the space inside each diaphragm compressor 210 has different volumes.

In addition, the diaphragm compressor 210 is connected through a pipe 201 in order from the diaphragm compressor 210 having the relatively largest volume to the diaphragm compressor 210 having the smallest volume, so that the fluid is each diaphragm. The fluid is gradually compressed by flowing the compressor 210 in order.

For example, the diaphragm compressor 210 has a first compressor 211 having a relatively largest volume and a second compressor 212 and a second compressor (2) having a smaller volume than the first compressor 211 ( It includes a third compressor (213) having a smaller volume than 212). That is, the first compressor 211 primarily compresses the original fluid injected in a state in which the fluid does not flow through the pipe 201. Thereafter, the primary compressed fluid flows through the pipe 201 to the second compressor 212. In addition, the second compressor 212 compresses the first compressed fluid injected in a state that prevents fluid from flowing to the pipe 201. Thereafter, the secondary compressed fluid flows through the pipe 201 to the third compressor 213. In addition, the third compressor 213 thirdly compresses the second compressed fluid injected in a state that prevents fluid from flowing to the pipe 201. Thereafter, the third compressed fluid flows through the pipe 201 to a fluid storage space (not shown). When the fluid is compressed in a stepwise manner in this way, it is possible to prevent the fluid having a reduced volume from flowing into a large space, thereby increasing the volume, thereby increasing the compression efficiency of the fluid.

In addition, the first compressor 211 is provided in the interior space of the third compartment 214 explosion-proof, the second compressor 212 is provided in the interior space of the explosion-proof designed fourth compartment 215, the first 3 compressor 213 may be provided in the interior space of the fifth compartment 216 explosion-proof design. In more detail, the first compressor 211 is provided inside the third compartment 214. Therefore, in case the fluid inside the first compressor 211 leaks and an explosion occurs, the first compressor in the third compartment 214 formed in a size similar to the volume of the first compressor 211 By installing 211, it is possible to reduce the thickness of the inner wall of the second compartment 200, which is relatively bulky. Likewise, the second compressor 212 is provided inside the fourth compartment 215. Therefore, in case the fluid inside the second compressor 212 leaks and an explosion occurs, the second compressor in the fourth compartment 215 formed in a size similar to the volume of the second compressor 212 By installing 212, it is possible to reduce the thickness of the inner wall of the second compartment 200, which is relatively bulky. Finally, the third compressor 213 is provided inside the fifth compartment 216. Therefore, in case the fluid inside the third compressor 213 leaks and an explosion occurs, the third compressor in the fifth compartment 216 formed in a size similar to the volume of the third compressor 213 By installing (213), it is possible to reduce the thickness of the inner wall of the second compartment 200, which is relatively bulky.

In addition, the fifth compartment 216 is formed to have a thicker inner wall than the fourth compartment 215, and the fourth compartment 215 has a thicker inner wall than the third compartment 214. Can be formed. That is, the thickness of the inner walls of the third compartment 214, the fourth compartment 215, and the fifth compartment 216 is different according to the degree of compression of the fluid. Because of this, even if an explosion accident occurs in any one of the first compressor 211, the second compressor 212, and the third compressor 213, so as not to cause damage to the rest of the portion except for the explosion. Is to do.

In addition, the fifth compartment 216 is formed to have a larger space therein than the fourth compartment 215, and the fourth compartment 215 is more inside than the third compartment 214 It can be formed to have a large space. This also changes the space inside the third compartment 214, the fourth compartment 215, and the fifth compartment 216 according to the degree of compression of the fluid. Because of this, even if an explosion accident occurs in any one of the first compressor 211, the second compressor 212, and the third compressor 213, so as not to cause damage to the rest of the portion except for the explosion. Is to do.

As a result, by providing the third compartment 214, the fourth compartment 215 and the fifth compartment 216, the thickness of the inner wall of the second compartment 200 can be reduced, so that the separated compressor system of the present invention The installation cost of can be dramatically reduced.

Next, the hydraulic generator 110 is provided. The hydraulic generator 110 includes a plurality of pistons 120 having different diameters and a driving unit 130 for reciprocating the pistons, and the pistons 120 are sequentially the diaphragm compressors according to the size of the diameter ( 210) are respectively connected by the hydraulic pipe 300 to correspond to the size of the volume.
