Description

Integrated air dryer system {one body type air dryer system}

The present invention relates to an integrated air dryer system, and more particularly, to an integrated air dryer system in which an adsorptive air dryer means and a plurality of dry air filters are integrally installed with compressed air supply means.

In general, air dryer systems are used in many industrial fields where compressed air is used, such as semiconductor manufacturing, electronics, medical, pharmaceutical, food, and chemical reaction industries. In addition, such an air dryer system is composed of an air compressor, an air dryer, an air filter, and the like, which sucks air in the atmosphere and compresses the air to a predetermined pressure, and provides the compressed air to various pneumatic devices through a predetermined line.

Here, reference numerals 75 and 76 denote air inlets and air outlets, respectively, and 77 denote drain valves for discharging the melt. In addition, the air dryer 73 is filled with aluminum gel.

On the other hand, looking at the operation of the conventional air dryer system as described above, first, the compressor 70 produces compressed air and supplies it to the air dryer 73 side through the air inlet (75). At this time, the compressed air made by the compressor 70 rises considerably, and when the initial inlet temperature of the compressed air is 38 ° C. or more, a problem of dissolving the solvent occurs.

Therefore, in order to solve the above problems, the cooler 71 is mounted at the front of the air dryer 73 to lower the temperature of the compressed air and then supply it to the air dryer 73 side. Then, the error dryer 73 dehumidifies the compressed air through the aluminum gel filled therein, and then outputs it to the filter 74. Therefore, the filter 74 removes the foreign matter in the compressed air and is then supplied to a desired place, for example, a clean room of a semiconductor factory or a precision paint factory.

However, the conventional air dryer system as described above takes a method in which the aluminum gel filled in the air dryer 73 is poured into the container and then discharged through the lower outlet when the service life is over, which waste aluminum gel is harmful to the human body. As it is an industrial waste, it seriously threatened the safety of the worker who handles it due to the dust. In addition, since the air dryer unit and the cooler including the compressor and the filter are separate parts, the piping is very complicated and the installation cost is high. Of course, there is a problem that the control convenience of the system is considerably deteriorated since it has to be greatly increased and controlled through a separate control module for each device.

Therefore, the present invention was invented to solve the above-mentioned problems, and since the air dryer means are all integrally installed, there is no need to install a separate control module for each equipment to control the system through one control module. The purpose is to provide an integrated air dryer system.

Another object of the present invention is to install a plurality of containers in which the entire body is composed of a perforated net in the adsorption air dryer, waste aluminum gel changer is easy to replace the waste aluminum gel by removing only the container with the perforated net formed aluminum gel harmful to the human body The present invention provides an integrated air dryer system that safely maximizes the stability of industrial waste treatment.

In addition, since all the air dryer means are integrally installed, the system can be controlled through a single control module without installing a separate control module for each equipment, thereby greatly improving the convenience of system control. Have

On the other hand, according to the present invention as described above, by installing a plurality of containers in which the entire body is made of a perforated net in the adsorption-type air dryer, the waste aluminum gel changer to remove only the container in which the perforated net is formed to easily replace with another container to the human body Safe handling of harmful aluminum gel also has the effect of maximizing the stability of industrial waste treatment.

The cooler means 3 includes an aftercooler 7 for cooling the temperature of the compressed air to, for example, 80 ° C. or higher to a temperature lower than a set temperature, for example, 40 ° C. or lower, and the after cooler 3. And a first filter element 8 for removing only 40 mu or more of moisture and dust contained in the compressed air output from 7).

In addition, the filter means (5) from the second filter element (9) for removing only 5μ or more foreign matter contained in the compressed air output from the refrigeration dryer (4), and from the second filter element (9) And a third filter element 10 for removing only 1 μ or more of foreign substances contained in the compressed air output, and a carbon filter 11 for removing oil contained in the compressed air output from the third filter element 3. It is configured by.

In addition, a fifth filter element 12 is connected to one end of the adsorption dryer 6 to remove, for example, 5 μm or more of foreign matter mixed in the air discharged from the adsorption dryer 6.

On the other hand, the adsorption-type dryer (6), as shown in Figure 4 is a plurality, that is, a plurality of two to accommodate the storage container (14A, 14B) consisting of the perforated net 13 in the whole that can contain the aluminum gel in close contact The first dryer member 15A and the second dryer member 15B are constructed.

Here, in the upper pipe between the first dryer member 15A and the second dryer member 15B, the first dryer member 15A according to the control signal of the control module 21 is provided with compressed air flowing from the filter means 5. Or a shuttle valve 16 for selectively supplying to the second dryer member 15B, and the first dryer member is provided in the lower pipe between the first dryer member 15A and the second dryer member 15B. A control valve 17 for discharging about 90% of the compressed air according to the control signal of the control module 21 from the 15A or the second dryer member 15B, and the first dryer member 15A and the second dryer. In the lower pipe between the members 15B, only about 10% of the air discharged from the first dryer member 15A or the second dryer member 15B according to the control signal of the control module 21 is not applied. By moving to the dry member 15A or the second dryer member 15B The solenoid valve 18 which dehumidifies the internal air in the said member is provided.

 Here, the storage container (14A, 14B) is provided with a cover member 19 that can open and close the top. In addition, discharge ports 22 through which the compressed air can be discharged are respectively provided at the lower sides of the first dryer member 15A and the second dryer member 15B.

In addition, in the description of the present invention, it is said that it is integrally formed on the system pedestal 20, the cooler means 3, the refrigeration dryer 4, the filter means 5, the adsorption dryer 6 and carbon This means that the filter 12 and the like are installed together in one system.

Next, the operation and effect of the device of the present invention having the above configuration will be described.

Operation of the present invention, the perforated network 13 is filled with aluminum gel in the storage containers (14A, 14B) formed in the entire body, and then covered with a cover member 19 and then the first dryer member (15A) of the adsorption dryer (6) ) And the second dryer member 15B to be in close contact with each other.

Then, the compressed air produced by the compressor 1 is supplied to the after cooler 7 of the cooler means 3 from the storage tank 2 in which the compressed air is stored. Then, the aftercooler 7 of the cooler means 3 cools the temperature of the supplied compressed air to, for example, 80 ° C or more to a predetermined temperature or less, for example, 40 ° C or less, and then supplies it to the first filter element 8. Let's do it. The first filter element 8 removes only 40 μ or more of moisture and dust contained in the compressed air output from the aftercooler 7 and outputs the same to the freeze dryer 4.

On the other hand, after the cooler process as described above, the refrigeration dryer 4 is cooled to, for example, 4 ° C. or less while removing moisture of the compressed air discharged from the first filter element 8 of the cooler means 3, and then the filter means. It outputs to the 2nd filter element 9 of (5).

Then, the second filter element (9) of the filter means (5) removes foreign substances contained in the compressed air output from the refrigeration dryer (4), for example, by removing only 5μ or more and outputs to the third filter element (10) Let's do it. The third filter element 10 removes, for example, 1 μm or more of foreign matter contained in the compressed air output from the second filter element 9, and then outputs the same to the carbon filter 11. Then, the carbon filter 11 removes the oil contained in the compressed air output from the third filter element (3) and then outputs it to the adsorption dryer (6).

At this time, the shuttle valve 16 installed on the upper pipe of the adsorption-type dryer (6) is the first dryer member (15A) or the compressed air flowing from the filter means (5) in accordance with the selection control signal of the control module (21) or It is selectively supplied to the second dryer member 15B.

For example, when compressed air is supplied from the control module 21 to the first dryer member 15A through the shuttle valve 16, the first dryer member 15A is an aluminum gel contained in a storage container 14A housed therein. By removing the moisture contained in the compressed air by the control module 2 outputs the compressed air to the fifth filter element 12 through the control valve 17 to remove the moisture.

At this time, the control valve 17 discharges only about 90% of the compressed air discharged from the first dryer member 15A. In addition, the solenoid valve 18 also moves only about 10% of the air discharged from the first dryer member 15A to another second dryer member 15B which is not currently actuated, thereby allowing the internal air in the member 15B to flow. After dehumidifying, it is discharged to the outside through the outlet 22.

Here, the drying process has been described on the assumption that compressed air is introduced into the first dryer member 15A, but only when the compressed air is introduced into the second dryer member 15B by the shuttle valve 16. The reverse is the same as the above procedure.

Meanwhile, the fifth filter element 12 removes, for example, 5 μm or more of foreign substances mixed in the air discharged from the adsorption dryer 6, and then, for example, a clean room or a precision coating plant of a semiconductor factory. It is transferred to and used for dust removal.

Here, the aluminum gel mounted on the storage containers (14A, 14B) of the first dryer member 15A and the second dryer member 15B after the compressed air is treated in one system as described above through the above process. When it is necessary to dispose of the worker, first open the cover of the first dryer member (15A) and the second dryer member (15B), and then take out the storage containers (14A, 14B). After the above process, instead of the taken out storage containers 14A and 14B, other new storage containers 14A and 14B are placed in the first dryer member 15A and the second dryer member 15B, and the aluminum gel, which is the industrial waste, is placed. Replace the entire storage containers 14A and 14B without having to remove them from the storage containers 14A and 14B.

Therefore, the worker can easily dispose of the aluminum gel, which is industrial waste, without being in particular contact with the industrial waste, so that dust of the aluminum gel, which is industrial waste, is not blown or scattered around, as in the conventional apparatus.

As described in the above description, the present invention is provided by installing the adsorptive air dryer means and the plurality of dry air filters integrally with the compressed air supply means, thereby simplifying the piping process and reducing the installation space. Also, since the entire container is provided with a perforated network, the entire container can be easily processed, and thus it is advantageous to apply it to an industry that requires a large amount of compressed air.
