Description

Pipeline structure for separating compressed air from moisture, oil and impurities

This creation is about compressed air, especially about the pipeline structure that supplies compressed air.

Compressed air is a very important power source for the manufacturing industry. In addition to being used to drive pneumatic tools and machines, it can also be used for dust removal, drying, bottle blowing and pressure setting, etc., and has a very wide range of applications.

Traditionally, compressed air can be produced by pressurizing air with an air pump. However, unfiltered air will contain moisture, oil, and impurities. During the compression process, it cannot remove moisture, oil, and impurities. Therefore, the compressed air generated by simple compression can only be used for driving simple pneumatic tools.

Therefore, as Taiwan’s patent No. I550245 “Compressed Air Oil-Free Purification System”, in order to remove the oil in the air, it uses low-temperature deceleration to increase the viscosity of the oil, make the water molecules larger, and make the water droplets easy to collide with the oil mist. (impact), and then form the condensation speed to accelerate to reach the oil droplets, which are filtered and assembled by the nano glass fiber, and return to large oil droplets, which are actively taken out by the electronic automatic sewage drainer, so as to achieve the output of clean oil-free air.

It is also like Taiwan Patent No. I547305 "Hollow Fiber Adsorption Compressed Air Drying System", which mainly forms a drying system by two hollow fiber adsorption cylinders, one of which is compressed air drying at room temperature and the other is hollow The fiber adsorption cylinder utilizes the surrounding heating device to perform desorption regeneration under high temperature environment, and its cycle switching can continuously produce dry compressed air with low dew point value.

The various compressed air treatment methods mentioned above all use external devices to remove moisture, oil and impurities by filtration, adsorption, etc., which is likely to cause large pressure loss. The filter materials and adsorption used The material has a flow resistance to the gas. As the use time increases, the degree of blockage gradually increases, and the pressure drop also gradually increases. Therefore, the power of the air pump needs to be increased, and there will be problems with device failure and consumable replacement, and its maintenance cost is high. , It is difficult to meet the demand for cost reduction.

The main purpose of this creation is to expose a pipeline structure with low installation cost and almost no maintenance, which can separate compressed air from moisture, oil and impurities.

Based on the above purpose, this work is a pipeline structure that separates compressed air from moisture, oil, and impurities, and is installed on a loop pipeline. It includes an intake pipe, a lower shunt pipe, an upper shunt pipe, and an outlet pipe , Wherein the intake pipe is serially connected to the loop pipeline, and the intake pipe is provided with a first tap, a second tap, a third tap and a fourth tap that are vertically connected and continuously arranged , Wherein the first tap and the fourth tap respectively have a tap outlet arranged downward, and the second tap and the third tap respectively have a tap outlet arranged upward.

The tap outlets of the first tap and the fourth tap are connected to both ends of the lower shunt, and the tap outlets of the second tap and the third tap are connected to both ends of the upper shunt And, the upper shunt tube is provided with a gas outlet tap connected vertically, the gas outlet tap has a tap outlet arranged upward, and the tap outlet of the gas tap is connected to the gas outlet pipe.

According to this, when the compressed air enters the intake pipe from the loop line, it will pass through the first tap or the fourth tap according to the direction of entry. When entering the first tap or the fourth tap When connecting, due to the structural factors of the pipeline and the effect of gravity, the liquid moisture, oil and solid impurities in the pipe will easily settle and condense and fall into the lower shunt; in addition, the liquid moisture itself will also Absorbs oil and impurities, while falling into the lower shunt, it also takes away oil and impurities together, so that the cleaner air can continue to move into the second tap or the third tap, When the compressed air enters the second tap or the third tap, because the liquid moisture, oil and solid impurities have a larger mass than the compressed air, it is not easy to turn upward due to the influence of inertial force and centrifugal force When entering the upper shunt tube, that is, the compressed air passing through the upper shunt tube will be relatively pure; when the compressed air of the upper shunt tube passes through the outlet tap, the same liquid water, oil, and solid impurities are not easy to turn upward and enter The air outlet pipe, that is, the compressed air entering the air outlet pipe is relatively pure.

In summary, the present invention can separate most of the water, oil, and impurities in the compressed air through three separations, and allow the purer compressed air to enter the outlet pipe, which uses a pipeline structure The design achieves the effect of separation, exerts the effects of gravity, inertial force and centrifugal force, and separates liquid water, oil and solid impurities from the gaseous compressed air flow, and finally obtains the compressed air with higher purity and low installation cost. And almost no maintenance, can meet the needs of reducing costs.

The detailed content and technical description of this creation are now further explained with examples, but it should be understood that these examples are for illustrative purposes only and should not be construed as limitations on the implementation of the creation.

Please refer to "Figure 1" and "Figure 2", the pipeline structure of this creation is to separate compressed air from moisture, oil, and impurities on a loop pipeline 10, which includes an intake pipe 20, a The shunt tube 30, an upper shunt tube 40, and an air outlet pipe 50, wherein the air inlet pipe 20 is serially connected to the loop pipe 10, the loop pipe 10 is connected to an air pump 11, and the air pump 11 is A compressed air 60 is generated and input into the loop line 10, and the diameter of the intake pipe 20 may be larger than that of the loop line 10, so when the compressed air 60 enters from the loop line 10 In the intake pipe 20, due to the increase in the cross-sectional area of the pipeline, the flow velocity in the pipe is reduced, the velocity momentum and the inertial force are weakened, which helps the moisture, oil, and impurities to settle in the pipeline more easily; The path 10 and the intake pipe 20 can be locked by a reducer 12. The intake pipe 20 is provided with a first tap 21, a second tap 22, a third tap 23 and a fourth tap 24 which are vertically connected and continuously arranged, wherein the first tap 21 and the The fourth tap 24 has a tap outlet 211, 241 arranged downward, respectively, the second tap 22 and the third tap 23 have a tap outlet 221, 231 arranged upward respectively, and the first The tap outlets 211, 241 of the one tap 21 and the fourth tap 24 are connected to both ends of the lower shunt tube 30, and the tap outlets 221, 231 of the second tap 22 and the third tap 23 To connect the two ends of the upper shunt tube 40, the upper shunt tube 40 is provided with an outlet tap 41 connected vertically, and the outlet tap 41 has a tap outlet 411 provided upward, and the outlet tap 41 The tap outlet 411 is connected to the air outlet pipe 50. In terms of actual structure, the first tap 21 and the fourth tap 24, the second tap 22 and the third tap 23 may be arranged in line symmetry with respect to the position of the outlet tap 41.

As also shown in FIG. 1, the lower shunt tube 30 may be provided with a drain tap 31 connected vertically, the drain tap 31 having a tap outlet 311 disposed downward, and the tap outlet of the drain tap 31 311 is connected to a drain pipe 32, the drain pipe 32 is provided with a drain valve 33, and the drain pipe An automatic drain 34 is provided below 32, so that moisture, oil and impurities can be automatically discharged by the automatic drain 34.

In addition, in order to supply the compressed air 60 of the present invention, a plurality of air outlet heads 51 can be provided on the air outlet pipe 50, the plurality of air outlet heads 51 can supply the compressed air 60, and an air outlet drain can be provided at the end of the air outlet pipe 50 The valve 52 and the air outlet and drain valve 52 can remove a small amount of sewage accumulated at the end of the air outlet pipe 50. In order to further purify the compressed air 60, the air outlet pipe 50 may have an upward extension 501 extending upward and connected to the air outlet tap 41. The upward extension 501 provides a path extending upward. The compressed air 60 During gas outlet, moisture, oil, and impurities are further suppressed from entering the gas outlet pipe 50. In order to facilitate operation and maintenance, the gas outlet pipe 50 may be provided with an outlet valve 53 between the plurality of outlet heads 51 and the outlet tap 41. The air outlet valve 53 can close the air outlet pipe 50, so that the compressed air 60 cannot pass through, and a barometer 54 can also be provided on the air outlet head 51, so that the user can immediately grasp the output pressure of the compressed air 60 to meet Need for use.

Please refer again to "Figure 3", which is a schematic diagram of the operating principle of the present invention. First, when the compressed air 60 enters the intake pipe 20 from the loop line 10, since the diameter of the intake pipe 20 is greater than The diameter of the loop line 10 reduces the flow velocity of the compressed air 60, which helps the sedimentation of moisture, oil and impurities in the tube; the reason is that when the air velocity is high, the airflow and moisture, oil, The larger shear stress between the impurity interfaces is not conducive to settling, but promotes mixing; therefore, by increasing the diameter of the pipe, the flow velocity in the pipe is slowed down, which in turn promotes the settlement of moisture, oil, and impurities in the airflow. And the compressed air 60 will change the direction of the compressed air 60 into the intake pipe 20 according to the pressure distribution of the loop line 10, so that the compressed air 60 passes through the first tap 21 from right to left, or Through the fourth tap 24 from left to right, as shown in "Figure 3" for drawing the compressed air 60 from right to left The situation of the first tap 21 is explained. In addition, the state of the compressed air 60 passing through the fourth tap 24 from left to right is completely symmetrical, and the description will not be repeated.

When the compressed air 60 enters the first tap 21, the flow path is divided into two, and the compressed air 60 will be split into two air flows 61 and 62. Due to the structural factors of the pipeline flow path and the effect of gravity, it has a relatively Heavy liquid water, oil and solid impurities will easily fall into the lower shunt tube 30 with the airflow 61, so the airflow 62 is the purer compressed air 60, which continues to enter the second tap 22, and Complete the first separation.

When the compressed air 60 enters the second tap 22, it will also split into two streams 63 and 64. Because the liquid water, oil and solid impurities have a larger mass than the compressed air 60, they are subject to inertia The influence of force and centrifugal force will continue to advance with the airflow 63, and it is not easy to enter the upper shunt tube 40 with the airflow 64 turning upward, that is, the compressed air 60 passing through the upper shunt tube 40 will be more pure, and complete the second Times of separation.

When the compressed air 60 of the upper shunt tube 40 passes through the outlet tap 41, it will also split into two streams 65 and 66, and the same liquid moisture, oil and solid impurities will continue to advance with the stream 65, and It is not easy to enter the air outlet pipe 50 with the airflow 66 turning upward, that is, the compressed air 60 entering the air outlet pipe 50 is relatively pure, and the third separation is completed.

Please also refer to "Figure 1" again. When the compressed air 60 enters the air outlet pipe 50, the plurality of air outlet heads 51 are not provided at the end of the air outlet pipe 50, thus allowing the remaining trace of moisture and oil The impurities accumulate at the end of the air outlet pipe 50 to avoid output from the plurality of air outlet heads 51, so the compressed air 60 provided can be more pure.

As described above, the present invention includes at least the following advantages.
