Description

Technical Field

[0001] This invention relates to the field of filtration technology, and in particular to an in-tube filtration device for a tubular indirect evaporative cooler. Background Technology

[0002] Indirect evaporative cooling technology pre-cools air at constant humidity, reducing the wet-bulb temperature of the processed air. Combined with direct evaporative cooling technology using a spray chamber, it can increase the temperature drop of air in the air-conditioned room, improve working conditions in the workshop, and reduce the mechanical refrigeration load, making it suitable for air conditioning systems in textile factories. Indirect evaporative coolers come in plate-fin, horizontal tube, and dew-point types, among which the horizontal tube type is widely used due to its wide flow channel, low cost, stable cooling effect, and long lifespan. However, the horizontal tube heat exchange tubes are relatively long, which can lead to easy clogging and difficulty in cleaning, as well as a large footprint in textile air conditioning systems with high dust concentrations. Therefore, the vertical tube type indirect evaporative cooler has emerged as a solution.

[0003] Filtration is a general term for a large class of unit operations, which are processes that purify fluids using specialized devices. There are many types of filtration, and the systems used are very diverse, including solid-liquid, solid-gas, large particles, and small particles. Filtration is the process by which liquid (or gas) in a suspension (or a gas containing solid particles and generating heat) is passed through a medium under the action of a driving force or other external force, while solid particles and other substances are retained by the filter medium, thereby separating the solids and other substances from the liquid (or gas).

[0004] During the installation and maintenance of tubular indirect evaporative coolers, improper operation can cause welding slag, small debris, and other impurities to seep into the system piping. Therefore, an in-pipe filter is needed to remove these impurities to prevent them from adversely affecting downstream throttling elements.

[0005] Existing in-tube filtration devices have certain drawbacks. In use, existing in-tube filtration devices usually only install a filter screen at one end of the tubular cooler. This can easily cause the fluid medium to backflow and adversely affect the throttling elements in the adjacent tubes. In addition, in-tube filtration devices can usually only perform single filtration, which reduces the filtration efficiency of the device. Therefore, we propose an in-tube filtration device for tubular indirect evaporative coolers. Summary of the Invention

[0030] Example 1

[0031] Reference Figure 1-6 As shown, an in-tube filtration device for a tubular indirect evaporative cooler includes a filtration mechanism and a fixing mechanism, which are symmetrically installed in the tubular indirect evaporative cooler. The fixing mechanism allows for detachable installation of the filtration mechanism. The filtration mechanism includes a first filtration assembly and a second filtration assembly detachably installed on the first filtration assembly. The first filtration assembly includes two sets of first filter plates 1 and a second filter plate 2 that is attached to the first filter plate 1. The second filtration assembly includes several sets of filter elements 3 installed on the side of the second filter plate 2 away from the first filter plate 1, and the several sets of filter elements 3 are installed sequentially at equal intervals on the second filter plate 2.

[0032] The size of several sets of filter elements 3 decreases from the outside to the inside.

[0033] Impurities may be present at both ends of the tubular indirect evaporative cooler during disassembly and installation; therefore, a filtration mechanism is used to filter them.

[0034] The tubular indirect evaporative cooler includes several sets of heat exchange tubes 15, which are arranged in parallel. The heat exchange tubes 15 are configured as vertical tubes. Each heat exchange tube 15 includes a tube body 4 and two sets of tube heads 5 symmetrically installed at both ends of the tube body 4. The tube body 4 and the tube heads 5 are detachable.

[0035] The first filter plate 1 and the second filter plate 2 are both installed at both ends of the tube body 4, and the two sets of first filter plates 1 and the two sets of second filter plates 2 are symmetrically installed on the tube body 4.

[0036] Both the first filter plate 1 and the second filter plate 2 are circular. Both the first filter plate 1 and the second filter plate 2 have through holes, and filter screens 6 can be detachably installed in the through holes. The size of the through holes on the first filter plate 1 is larger than the size of the through holes on the second filter plate 2.

[0037] Several sets of filter elements 3 are all set inside the tube head 5, and the filter element 3 is a cylindrical structure with an opening at one end.

[0038] The diameter of several sets of filter elements 3 decreases from the outside to the inside, and the several sets of filter elements 3 are arranged to wrap around each other in sequence. The size of the innermost filter element 3 is larger than the size of the second filter plate 2.

[0039] Adjust the filtration mechanism so that the first filter plate, the second filter plate and the filter elements are all installed inside the tube body 4. When the fluid medium in the tubular indirect evaporator passes through several sets of filter elements 3 in sequence, the several sets of filter elements 3 perform preliminary filtration of impurities in the fluid medium. Then, when the fluid medium passes through the filter screens 6 on the first filter plate 1 and the second filter plate 2 in sequence, the impurities in the fluid medium are filtered again.

[0040] When the fluid medium is recirculated, it is filtered by the combination of the filter element 3, the second filter plate 2 and the first filter plate 1.

[0041] In this invention, the filter mechanism, with the first filter plate 1 and the second filter plate 2 working together, can filter impurities inside the tube 4. Furthermore, the several sets of filter elements 3 can perform multiple filtrations of impurities, improving the filtration efficiency of the device. The first filter plate 1, the second filter plate 2, and the filter elements 3, symmetrically installed on the tube 4, can improve the filtration effect of the tubular indirect evaporative cooler, avoid adverse effects on the throttling elements inside adjacent tubes, facilitate user use, and improve the applicability of the filtration device.

[0049] Adjust the fixing mechanism, rotate the first filter plate 1, and install it in the first fixing groove by thread. Rotate the second filter plate 2, and install it in the first fixing groove by thread, so that one side of the second filter plate 2 and one side of the first filter plate 1 are in contact. Install both the first filter plate 1 and the second filter plate 2 onto the first fixing seat 7.

[0050] Rotate the filter element 3 to drive the fixing block 9 to rotate, install the fixing block 9 into the second fixing groove, and fix the filter element 3 and the second fixing seat 8 together. Install several sets of filter elements 3 onto the second filter plate 2 in sequence.

[0051] In this invention, the first filter plate 1 and the second filter plate 2 are detachably connected to the first fixed seat 7 through the fixed mechanism, and the fixed block 9 and the second fixed seat 8 are detachably connected. This allows for the detachable installation of several sets of filter elements 3, making it convenient for staff to disassemble and maintain them, and for people to use them, thus increasing the applicability of the entire filtration device.
