Description

Technical Field

[0001] The utility model relates to the technical field of cooling water filtration, in particular to a filter suitable for a cooling water system of a data center. Background Art

[0002] Driven by technologies and businesses such as artificial intelligence, big data, machine learning, high-definition video, AR, and VR, the demand for data center construction will accelerate, and the popularity of energy conservation and carbon reduction throughout the life cycle of data centers will continue to increase.

[0003] At present, the cooling method of the computer room air conditioning in the data center is mainly water-cooled. The cooling tower of the water-cooled air-conditioning system is exposed to the air for a long time, and the cooling water therein will contain a large amount of particulate matter, catkins and various microorganisms. These substances will adhere to the inner surface of the equipment pipe, causing the heat transfer capacity of the equipment to deteriorate and the circulation pressure inside the equipment to increase, thereby reducing the heat exchange efficiency of the equipment and increasing the energy consumption of the equipment. In severe cases, it will cause critical consequences such as blockage, perforation, leakage, etc., making it impossible for the data center to operate safely, stably and continuously.

[0004] Water purifiers are now commonly used to remove particulate matter and catkins from cooling water. After the cooling water enters the water purifier, it is first precipitated to separate the particulate matter from the cooling water, and then filtered to separate the catkins from the cooling water.

[0005] Existing water purifiers usually use natural sedimentation to precipitate cooling water. However, natural sedimentation is slow in separating particulate matter from cooling water. Therefore, the purification efficiency of existing water purifiers for cooling water is low. Summary of the invention

[0006] The utility model provides a filter suitable for a cooling water system of a data center to overcome the above technical problems.

[0007] In order to achieve the above purpose, the technical solution of the utility model is:

[0008] A filter for a cooling water system in a data center comprises a filter tank body, an inlet pipe, an outlet pipe and a drain pipe, wherein the inlet pipe, the outlet pipe and the drain pipe are all connected to the filter tank body, the drain pipe is connected to the bottom of the filter tank body, and a turbulence device connected to the output end of the inlet pipe is arranged in the filter tank body; the turbulence device comprises a first flow guide member and a second flow guide member; the first flow guide member is a cylindrical structure with an axis perpendicular to a horizontal plane and open at both the upper and lower ends, and the second flow guide member is a cylindrical structure with an axis perpendicular to a horizontal plane and open at the upper end and closed at the lower end, The upper end of the first flow guide member is connected to the output end of the water inlet pipe, and the lower end of the first flow guide member is connected to the upper end of the second flow guide member; the outer wall of the first flow guide member is vertically arranged, and a plurality of first water outlet holes are evenly distributed and opened on the outer wall of the first flow guide member, and the axis of the first water outlet hole is perpendicular to the outer wall of the first flow guide member; the outer wall of the second flow guide member is inclined upward, and a plurality of second water outlet holes are evenly distributed and opened on the outer wall of the second flow guide member, and the axis of the second water outlet hole is perpendicular to the outer wall of the second flow guide member.

[0009] Furthermore, a first partition is installed above the turbulence device in the filter tank body, and a plurality of water distributors are evenly distributed and installed on the first partition. The input end of the water distributor is connected to the bottom of the first partition in the filter tank body, and the output end of the water distributor is connected to the top of the first partition in the filter tank body.

[0010] Furthermore, a second partition is installed above the first partition in the filter tank body, and one or more filter screen installation holes are opened on the second partition. The filter screen installation holes connect the top and bottom of the second partition in the filter tank body, and a filter screen is installed in the filter screen installation hole.

[0011] Furthermore, the input end of the water outlet pipe is connected to the top of the second partition plate in the filter tank body.

[0012] Furthermore, an exhaust port is provided on the top of the filter tank.

[0013] Furthermore, a pressure sensor is provided in the filter tank.

[0014] Furthermore, a maintenance passage is provided on the side wall of the filter tank.

[0015] Furthermore, a plurality of hoisting components are evenly distributed and installed on the top of the filter tank.

[0016] Furthermore, the bottom of the filter tank is evenly distributed and equipped with a plurality of legs.

[0017] Beneficial effects:

[0018] In the utility model, cooling water enters the turbulent flow device through the water inlet pipe, and then enters the filter tank body through the first water outlet hole on the first flow guide component and the second water outlet hole on the second flow guide component. Since the outer wall of the first flow guide component is vertically arranged and the axis of the first water outlet hole is perpendicular to the outer wall of the first flow guide component, the water flow direction of the cooling water output by the first water outlet hole is parallel to the horizontal plane. Since the outer wall of the second flow guide component is inclined upward and the axis of the second water outlet hole is perpendicular to the outer wall of the second flow guide component, the water flow direction of the cooling water output by the second water outlet hole is inclined upward. Since the second flow guide component is located below the first flow guide component, the cooling water output by the second flow guide component will impact the cooling water output by the first flow guide component, forming a turbulent flow area in the filter tank body. The turbulent flow will accelerate the sedimentation speed of particulate matter in the cooling water, so that the particulate matter is separated from the cooling water more quickly. Therefore, the utility model has a higher purification efficiency for cooling water. BRIEF DESCRIPTION OF THE DRAWINGS
