- the pneumatic equipment is defined as a device that converts mechanical energy into gas energy by a compressor, a blower, etc., and controls the compressor body with a control valve or the like and supplies it to the actuator to output the output as mechanical energy suitable for the load demand. can do.
- the compressed air is made by compressing the air of the atmosphere, the air is mixed with a lot of pollutants, including moisture, dust, etc., and the contaminants are also compressed in the process of compression with a compressor to increase the pollution.
- compressed air purifiers are commonly referred to as "air filters” in the general type, and “mist separators” or “demisters” in the case of water removal only, to remove moisture contained in the compressed air.
- air filters in the general type
- mis separators or “demisters” in the case of water removal only, to remove moisture contained in the compressed air.
- a principle is used in which compressed water is collected by passing through the filter element so that moisture is not caught in the fine hole of the filter element.
- the conventional filter element is composed of a microporous structure such as a nonwoven fabric, a plastic sintered body, and a metal sintered body, a "blocking" phenomenon inevitably occurs due to the growth of dust or bacteria as the use time elapses. Therefore, the new filter element will function normally for a certain period of time after the replacement of the new filter element, but the blockage of the fine pores will proceed as the use time elapses, and as the blockage progresses, the cross-sectional area through which air can pass decreases, allowing compressed air to pass through. Becomes difficult. Therefore, the pressure loss increases. This results in waste of energy and the outlet pressure drops below the required pressure. Therefore, the filter element should be replaced when the pressure difference between the front and rear ends of the filter element becomes larger than a certain amount.
- the filter element must be replaced regularly as a consumable, and when the filter housing is opaque, there is a problem in that it is difficult to grasp the degree of blockage because the filter element is not visible inside, thus missing a replacement time.
- finer pore filter elements should be used as the compressed air of high cleanliness. The problem caused by clogging is more remarkable as the pore of the filter element becomes finer.
- pressure gauges are installed at the front and rear ends of the dehumidifier for compressed air, or differential pressure gauges are used to identify the pressure difference, which increases the installation cost, increases the installation space, and consequently maintenance. Additionally involved.
- centrifugal compressed gas purifiers are constructed such that an exhaust cylinder installed inside the housing, a spiral groove formed on the circumferential surface of the exhaust cylinder, and contaminants are collected on the inner wall of the housing, and the clean compressed gas flows to the center of the housing. It is a centrifugal type compressed gas purification apparatus characterized by the above-mentioned.
- Compressor flow converted into rotational state by entering the intake pipe and being blocked by the baffle plate is rotated in the circumferential direction around the vent in the primary vortex chamber formed inside the housing. Perform.
- the compressor body passing through the primary vortex chamber maintains the spiral flow along the double row spiral groove formed on the circumferential surface of the exhaust cylinder in the secondary vortex chamber formed between the inner surface of the housing and the exhaust cylinder.
- Gas-liquid separation On the other hand, the liquid centrifuged from the compressor body is collected and separated from the inner wall of the housing through the circumferential space formed between the inner wall of the housing and the outer circumferential surface of the double row spiral groove.
- the gas purified by centrifugation is sent to the pneumatic equipment through the vent and the outlet nipple connected to the exhaust pipe and the external gas pipe.
- the liquid or condensed water separated in the secondary vortex chamber and the tertiary vortex chamber are collected in the sump inside the drain box located at the bottom of the housing and discharged to the outside through the trap through the final drain.

Therefore, the user does not need to operate to discharge impurities separately.
- the discharge pin 670 is lowered, and as shown in Figure 7c, the discharge pin 670 hits the protrusion of the lower surface of the lower collecting chamber 615, the lowering stops. At this time, the upper portion of the upper pin 671 is in close contact with the O-packing c (656) to block the communication between the upper space 690 and the central space (692). Thus, the high pressure compressed air introduced through the hole 653 no longer exits the air passage 680.
- the upper space 690 is a high pressure state
- the central space 692 is an atmospheric pressure flows into the atmospheric air through the air flow path 680
- the lower space 691 is a high pressure state.
- the first impurity and the second impurity is discharged through the discharge port 611, the lower collecting chamber 615 because the pressure drop occurs, the pressure difference between the collecting container 630 and the lower collecting chamber 615 instantaneously. Occurs.
- the second impurity of the collecting container 630 pushes the U-packing a (643) and moves to the lower collecting chamber (615).
- the U-packing a 643 is communicated in the direction of the lower collecting chamber 615 from the collecting container 630 when the open portion is disposed downward and the pressure blocking unit 641 is lowered. That is, it communicates in one direction.
- the U-packing a plays an important role in the rise of the pressure blocking unit 641, and at the same time allows the second impurity collected in the collecting container 630 to move toward the lower collecting chamber (615).
- the first chamber 420 in which the high pressure is formed and the second chamber 460 in which the low pressure is formed are in communication with the drain cover 610 and the collecting container 630, additional power is required for the discharge of impurities.
