[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] A liquid dewatering device, such as Figure 1 As shown, the liquid dewatering device consists of three filter components: filter cylinder 1, filter cylinder 2, and filter cylinder 3. The three filter cylinders are installed side by side on the fixed frame 4, and the adjacent filter cylinders are interconnected. An indicator 5 is fixedly provided on the top of filter cylinder 2.

[0028] like Figures 2-4 As shown, a filter screen 11 is fixedly installed in the middle of the end cap of filter cylinder 1 for filtering moisture in the gas. A primary gas delivery channel 6 is connected to the filter screen 11. The gas to be treated enters the filter cylinder 1 from the hole 10 on one side of the end cap of filter cylinder 1. The gas enters from the outside and bottom of the filter screen 11 and passes through the filter screen 11, and then is delivered to the primary gas delivery channel 6.

[0029] An installation pipe 22 connected to the primary gas supply channel 6 is fixedly installed inside the filter cylinder 2. An extension pipe 21 is connected to the end of the installation pipe 22. A filter section 24 is fixedly installed on the outside of the extension pipe 21. The filter section 24 is filled inside the filter cylinder 2. A support member 23 is fixedly installed at the bottom of the extension pipe 21. The support member 23 has a hollow structure. The filter section 24 is attached to the support member 23. Gas is supplied from the primary gas supply channel 6 into the installation pipe 22 and then enters the filter section 24. It is transported along the filter section 24 to the bottom of the support member 23. At this time, the gas passes through the filter section 24 from bottom to top, and the gas is filtered to achieve oil mist separation.

[0030] A secondary gas supply channel 7 is provided inside the end cap of filter cartridge 2 and outside the mounting pipe 22. The gas after oil mist separation is supplied into the secondary gas supply channel 7.

[0031] A cotton filter element 31 is fixedly installed in the middle of the end cap of filter cartridge 3. The cotton filter element 31 is connected to the secondary air supply channel 7. A frame 32 is provided on the outside of the cotton filter element 31. A drying part 33 is fixedly installed on the outside of the frame 32. The drying part 33 includes a pearl cotton layer, a cotton cloth layer and an outer white net arranged from the inside to the outside.

[0032] A desiccant is filled between the frame 32 and the cotton filter element 31. The desiccant can be made of silica gel. When the gas enters the cotton filter element 31, it then disperses outward from the cotton filter element 31. After passing through the desiccant and the drying section 33, the gas is dried and then discharged from the outlet 34 on one side of the end cap of the filter element 31.

[0033] A pressure hole 25 is provided on the top of the end cap of filter cylinder 2. The pressure hole 25 is connected to the inside of filter cylinder 2 to monitor the internal pressure changes. An air groove 50 is provided in the indicator 5. The air groove 50 is connected to the pressure hole 25. An indicator block 51 is slidably provided in the air groove 50. A spring 52 is fixed on the top of the indicator block 51. One end of the spring 52 is connected to the top of the indicator 5. The indicator 5 is made of transparent material. When the gas pressure in the pressure hole 25 increases, it will push the indicator block 51 to move upward, and the spring 52 will be compressed. Then, by observing the height position of the indicator block 51, the pressure change inside filter cylinder 2 can be judged. If the indicator block 51 is abnormally pushed up, it proves that there is a blockage inside the inner filter cylinder 2, resulting in an increase in air pressure.

[0034] The working principle is as follows:

[0035] Connect the gas supply line to the channel 10 so that the gas to be treated is supplied into the channel 10. Then the gas to be treated is continuously supplied from the channel 10 into the filter cartridge 1. After passing through the filter screen 11, it enters the primary gas supply channel 6. The gas with the moisture removed is then fed into the installation pipe 22 and then into the filter section 24. It is then transported along the filter section 24 to the bottom of the support member 23. At this time, the gas passes through the filter section 24 from bottom to top, and the gas is filtered to achieve oil mist separation.

[0036] Finally, the gas enters the cotton filter element 31 from the secondary gas transmission channel 7, diffuses outward from the cotton filter element 31, and gradually passes through the desiccant, pearl cotton layer, cotton cloth layer and outer white mesh to perform the final drying treatment on the gas, so that when the gas is discharged, the internal moisture content is reduced to meet the requirements of the gas.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
