Abstract
Description
Technical Field
[0001] This application relates to the field of air separation process technology, and in particular to an air separation circulating water system. Background Technology
[0002] In the air separation process, the compressor generates a large amount of heat during operation. To ensure continuous production, this heat needs to be dissipated. The main equipment for heat dissipation is the intercooler. The effectiveness of the intercooler determines whether the process can operate continuously and whether energy consumption is economical. The cooling source for the intercooler is circulating water; therefore, the quality of the circulating water is one of the key indicators affecting the intercooler's performance.
[0003] Currently, the mainstream method for filtering impurities in circulating water is to install a metal filter screen at the inlet of the water pump. However, the impurities filtered out by this method are inconvenient to discharge. To address this, the inventors have proposed an air separation circulating water system. Utility Model Content
[0004] This application provides an air separation circulating water system that facilitates the discharge of filtered impurities.
[0005] The technical solution of this application is as follows:
[0006] This application provides an air separation circulating water system, including multiple layers of conical filter screens spaced apart along the axial direction of the cylinder, a slag discharge pipe at the axis of the filter screens, an regulating pipe screwed onto the axis of the cylinder, and a slag discharge port on the side wall of the regulating pipe that is closed by the slag discharge pipe.
[0007] By adopting the technical solution of this application, the slag discharge port is moved to the top of the slag discharge pipe by rotating the regulating pipe. At this time, the impurities on the filter screen will flow into the regulating pipe from the slag discharge port and finally be discharged from the lower port of the regulating pipe to the outside of the cylinder, which facilitates the discharge of the filtered impurities.
[0008] In some implementations, a water inlet is provided at the top of the cylinder.
[0009] In some implementations, the water inlet is eccentrically positioned relative to the axis of the cylinder.

[0012] In some implementations, the connecting ring is screwed onto the inner wall of the cylinder.
[0013] In some implementations, multiple filter screens are distributed at equal intervals along the axial direction of the cylinder.
[0014] In some implementations, the inner diameter of the slag discharge pipe is equal to the outer diameter of the regulating pipe.
[0015] In some implementations, the slag discharge ports are evenly distributed along the circumference of the regulating pipe.
[0016] In some implementations, the axial length of the slag discharge port is less than the axial length of the slag discharge pipe. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.
[0026] In related technologies, the compressor in the air separation process generates a large amount of heat during operation. To ensure continuous production, this heat needs to be dissipated. The main equipment for heat dissipation is the intercooler. The effectiveness of the intercooler determines whether the process can operate continuously and whether energy consumption is economical. The cooling source for the intercooler is circulating water; therefore, the quality of the circulating water is one of the key indicators affecting the intercooler's operating performance.
[0027] Currently, the mainstream method for filtering impurities in circulating water is to install a metal filter screen at the inlet of the water pump. However, the impurities filtered out by this method are not easy to discharge.
[0028] This embodiment provides an air separation circulating water system that facilitates the discharge of filtered impurities.
[0029] Please see Figures 1-3 In this embodiment, an air separation circulating water system includes multiple layers of conical filter screens 20 spaced apart along the axial direction of the cylinder 10. A slag discharge pipe 21 is provided at the axis of the filter screen 20, and an regulating pipe 30 is screwed onto the axis of the cylinder 10. The side wall of the regulating pipe 30 is provided with a slag discharge port 31 that is closed by the slag discharge pipe 21.
[0030] Using the technical solution of this embodiment, by rotating the regulating pipe 30, the slag discharge port 31 is moved above the slag discharge pipe 21. At this time, the impurities on the filter screen 20 will flow into the regulating pipe 30 from the slag discharge port 31 and finally be discharged from the lower port of the regulating pipe 30 to the outside of the cylinder 10, so as to facilitate the discharge of the filtered impurities.
[0031] In this embodiment, the cylinder 10 is constructed as a cylinder. A water inlet 11 is provided at the top of the cylinder 10, and a drain outlet 12 is provided on the side wall of the cylinder 10 near the bottom. At the same time, four support legs 13 for maintaining stability are provided at the top of the cylinder 10. The axis of the water inlet 11 is eccentrically arranged with respect to the axis of the cylinder 10, that is, the axis of the water inlet 11 is parallel to the axis of the cylinder 10, and the axis of the water inlet 11 is arranged outside the axis of the cylinder 10. The axis of the drain outlet 12 is perpendicular to the axis of the cylinder 10.
[0032] In this embodiment, the filter screen 20 is constructed as a cone shape that is wider at the top and narrower at the bottom. The filter screen 20 is coaxially arranged with the cylinder 10. A connecting ring 22 is fixed to the outer edge of the filter screen 20 and screwed onto the inner wall of the cylinder 10, so that the filter screen 20 can be detachably installed inside the cylinder 10. The slag discharge pipe 21 is fixed to the axis of the filter screen 20 and passes through the filter screen 20, so that impurities on the filter screen 20 can slide into the slag discharge pipe 21 along the slope formed by the filter screen.
[0033] It should be noted that in this embodiment, the three-layer filter screen 20 is distributed at equal intervals along the axial direction of the cylinder 10, and the mesh size of the three-layer filter screen 20 decreases from top to bottom along the axial direction, which can achieve multiple filtration effects on water.
[0034] In this embodiment, the regulating pipe 30 is screwed into the axis of the cylinder 10. The regulating pipe 30 passes through the inside of the slag discharge pipe 21, and the outer diameter of the regulating pipe 30 is equal to the inner diameter of the slag discharge pipe 21. A slag discharge port 31 is provided on the regulating pipe 30. The slag discharge ports 31 are evenly distributed along the circumference of the regulating pipe 30. At the same time, multiple sets of slag discharge ports 31 are evenly distributed along the axial direction of the regulating pipe 30. Each set of slag discharge ports 31 is arranged correspondingly to the slag discharge pipe 21. The axial length of the slag discharge port 31 is less than the axial length of the slag discharge pipe 21, so that the slag discharge pipe 21 can completely close the slag discharge port 31.
[0035] It should be noted that when filtering water, the slag discharge port 31 moves into the slag discharge pipe 21 and the slag discharge port 31 is in a closed state, and impurities will be collected on the surface of the filter screen 20.
[0036] When in use, when it is necessary to remove impurities from the filter screen 20, rotate the regulating tube 30 upward a certain distance so that the slag discharge port 31 moves above the slag discharge pipe 21. At this time, the space above the filter screen 20 is connected to the regulating tube 30 through the slag discharge port 31. Then, clean water is introduced into the cylinder 10. Under the impact of the clean water, the impurities flow into the regulating tube 30 through the slag discharge port 31 and are finally discharged from the lower end of the regulating tube 30.
[0037] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
