Description

Technical Field

[0001] This utility model relates to the field of circulating water systems, and specifically to a side-filter structure for a circulating water system. Background Technology

[0002] Cooling towers are key equipment in circulating water treatment systems. According to existing technology, about 5% of the water flow in the cooling tower return water header is treated by a bypass filter and then flows directly into the cooling tower collection pool. This part of the water flow does not undergo cooling treatment by the cooling tower, which will cause a certain temperature rise in the cooling tower outlet water, and there is room for improvement. Utility Model Content

[0003] In view of the problems existing in the background art, the purpose of this utility model is to provide a side-filter structure for a circulating water system, which effectively solves the problems existing in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A bypass filtration structure for a circulating water system includes a cooling tower, a cooling tower return water header, a bypass filter, a bypass filter inlet pipe, and a bypass filter outlet pipe. The inlet of the bypass filter is connected to the cooling tower return water header via the bypass filter inlet pipe, and the bypass filter outlet pipe is connected to the cooling tower's water collection tank. A branch pipe is also connected to the bypass filter outlet pipe. Valves are respectively installed on the branch pipe and the bypass filter outlet pipe. The outlet of the branch pipe extends into the cooling tower and is located above the water collection tank.

[0006] Furthermore, the outlet of the branch pipe is located above the packing layer inside the cooling tower.

[0007] Furthermore, the outlet of the branch pipe is located below the packing layer inside the cooling tower.

[0008] Furthermore, a spray pipe or spray head is provided at the outlet of the branch pipe.

[0009] This utility model has the following beneficial technical effects:

[0010] The bypass filter of this invention has a branch pipe connected to its outlet pipe, which can spray part or all of the bypass filter water into the cooling tower for cooling as needed. Compared with the bypass filter water being directly discharged into the collection tank, this can effectively reduce the impact of the bypass filter water into the temperature of the cooling tower water after it flows into the collection tank. Moreover, the cooling process of this part of the water flow does not require the cooling tower's pump to do work, which reduces the circulating water volume and also reduces the energy consumption of the cooling tower's pump, thus contributing to the achievement of energy conservation and emission reduction goals.

[0013] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0014] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," and "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] Example 1

[0016] like Figure 1 As shown in the figure, the side-filter structure of the circulating water system described in this embodiment includes a cooling tower 1, a cooling tower return water main pipe 2, a side filter 3, a side filter inlet pipe 4, and a side filter outlet pipe 5. The cooling tower return water main pipe 2 is connected to the spray pipe layer 7 inside the cooling tower 1 through a water supply pipe 6. A cooling tower matching water pump is installed on the water supply pipe 6. The inlet of the side filter 3 is connected to the cooling tower return water main pipe 2 through the side filter inlet pipe 4. The side filter outlet pipe 5 is connected to the water collection tank 8 of the cooling tower 1. A branch pipe 9 is also connected to the side filter outlet pipe 5. Valves are respectively installed on the branch pipe 9 and the side filter outlet pipe 5, so that the flow rate of the branch pipe 9 and the flow rate of water directly discharged into the water collection tank 8 inside the cooling tower 1 can be selected as needed.

[0017] The outlet of branch pipe 9 extends into the cooling tower 1 and is located above the water collection pool 8. Specifically, the outlet of branch pipe 9 is located above the packing layer 10 inside the cooling tower 1.

[0018] The water from branch pipe 9 flows through the packing layer 10 and falls into the water collection pool 8 of cooling tower 1. The water from branch pipe 9 is fully cooled. Compared with the direct discharge of the water from the side filter 3 into the water collection pool 8, this can effectively reduce the impact of the water from the side filter 3 into the water collection pool 8 on the temperature of the water from the cooling tower 1. Moreover, the cooling process of this part of the water flow does not require the cooling tower's matching water pump to do work, which reduces the circulating water volume and also reduces the energy consumption of the cooling tower's matching water pump, thus contributing to the achievement of energy conservation and emission reduction goals.

[0019] The outlet of the preferred branch pipe 9 is equipped with a spray pipe or spray head, which can better disperse the water from the branch pipe 9 and ensure the cooling effect.

[0020] Example 2

[0021] like Figure 2 As shown, the difference between this embodiment and embodiment one is that the outlet of branch pipe 9 is located below the packing layer 10 inside the cooling tower 1. Compared with the water outlet of branch pipe 9 completely passing through the packing layer 10, the cooling effect is reduced but still has a certain cooling effect. The advantage is that it is simple to set up and has the function of drawing air inward, which can increase the air cooling of the packing layer 10 and facilitate the completion of the overall heat load of the cooling tower 1. The other parts of this embodiment are the same as those of embodiment one, and will not be described again here.

[0022] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
