Description

Technical Field

[0001] The utility model belongs to the technical field of cooling tower water recovery, in particular to a packing layer falling water recovery device for a cooling tower. Background Art

[0002] Cooling towers are commonly used industrial equipment to reduce the temperature of circulating water, and the packing layer is a key component for air-water heat exchange in cooling towers. In cooling towers, circulating water exchanges heat with air when passing through the packing layer. When the water temperature drops, it will drip downwards. In order to avoid waste, a recovery mechanism is often added to collect and reuse the falling water.

[0003] At present, it is found in the actual recycling operation of the existing packing layer falling water that when the falling water passes through the packing layer for heat exchange, it will carry some impurities, microorganisms or chemicals, causing water pollution. The existing treatment method is to centrally treat the water after it is pumped out. However, during the process of water extraction, impurities will remain inside the pipe, forming dirt that affects the subsequent use effect, and it is also easy to corrode the pipeline and cause damage;

[0004] In order to solve the above problems, the present application proposes a packing layer water recovery device for a cooling tower. Utility Model Content

[0007] The utility model discloses a packing layer falling water recovery device for a cooling tower, comprising: an outer ring frame connected to the packing layer of the cooling tower; a water collecting pan with an inverted cone structure guides the falling water to a middle area after receiving the falling water, an inner row pipe is provided at the lower end of the water collecting pan, and a conical filter frame is installed inside the water collecting pan to separate impurities in the falling water at the first time to prevent the impurities from entering the return water pipeline and causing corrosion; a guide platform is also provided on the inner side of the inner row pipe to guide and gather the impurities, and a storage tank is provided on the outer side of the inner row pipe for storing the separated impurities.

[0008] Furthermore, a guide plate is provided on the inner side of the water collecting tray to guide the falling water to the surface of the conical filter frame, and a drain filter frame is provided at the lower end of the conical filter frame, which cooperates with the guide platform and the inner wall of the inner drainage pipe to form an annular space for temporarily storing impurities.

[0009] Furthermore, a partition plate and a bottom plate are provided in upper and lower layers inside the lower end of the outer ring frame, and the bottom plate is a conical structure for settling impurities in a central area for centralized treatment.

[0010] Furthermore, a drainage pipe is provided above the partition to discharge impurities inside the storage tank, and a water pump is also provided above the partition to discharge precipitated water.

[0013] Furthermore, the drainage filter rack is used to automatically form a drainage effect when the impurities carry too much water.

[0014] The utility model has the following beneficial effects:

[0015] The utility model can collect the falling water directly through the water collecting tray and concentrate it inside the inner drainage pipe by adding an outer ring frame below the packing layer. At this time, the impurities are filtered through the conical filter frame, and the impurities are separated from the water at the first time to avoid the impurities remaining on the inner wall of the pipe to form dirt and corrosion when discharged. Compared with the existing treatment method, the service life of the equipment can be greatly improved, which is conducive to the efficient and stable use of falling water collection operations;

[0016] The utility model can collect the stored impurities downwards through the guide platform and discharge them into the storage tank through the transfer pipe for storage. After this arrangement, the stored impurities can be discharged at any time without frequent cleaning and no need to worry about impurities clogging the pipeline. The difficulty of falling water recovery work is reduced, the cleaning process is omitted, and the use effect of the equipment is improved.

[0027] See also Figure 1-4 As shown, the utility model is a packing layer water recovery device for a cooling tower, comprising: an outer ring frame 1 connected to the packing layer of the cooling tower; a water collecting pan 2 with an inverted cone structure guides the water to the middle area after receiving the water, and an inner pipe 4 is provided at the lower end of the water collecting pan 2, and a conical filter frame 7 is installed inside the water collecting pan 2 to separate impurities in the water immediately to prevent the impurities from entering the return water pipeline and causing corrosion;

[0028] A guide platform 12 is also provided on the inner side of the inner row pipe 4 to guide the impurities to gather, and a storage tank 13 is provided on the outer side of the inner row pipe 4 to store the separated impurities;

[0029] The present embodiment provides a water recovery mechanism for the packing layer in the cooling tower which can conveniently separate impurities. The conical filter frame 7 is used to filter the water immediately after the water is collected, so that the impurities can be separated and stored in the storage tank 13 after being guided by the guide platform 12. This can effectively prevent the impurities from remaining in the return water pipeline to form dirt and corrode the pipeline.

[0030] Among them, a guide plate 3 is provided on the inner side of the water collecting tray 2 to guide the falling water to the surface of the conical filter frame 7 to prevent the falling water from dripping everywhere and affecting the filtering effect. A drain filter frame 11 is provided at the lower end of the conical filter frame 7, which cooperates with the guide platform 12 and the inner wall of the inner drainage pipe 4 to form an annular space for temporarily storing impurities.

[0031] Among them, the lower end of the outer ring frame 1 is layered with a partition 5 and a bottom plate 6. The bottom plate 6 is a conical structure, which is used to precipitate impurities in the central area for centralized treatment, so that the filtered water forms a secondary separation (impurity precipitation) effect.

[0032] A discharge pipe 8 is provided above the partition 5 to discharge impurities in the storage tank 13 , and a pumping pipe 9 is provided above the partition 5 to discharge precipitated water.

[0033] Among them, a limit valve 10 is provided at one end of the impurity discharge pipe 8 to control the regular discharge operation of impurities and prevent impurities from remaining in the pipeline.

[0034] The upper end of the storage tank 13 is provided with a transfer tube 14 connected to the inner row pipe 4 and connected to the lowest point of the guide platform 12, so that impurities can slide down along the inclined structure and be automatically collected.

[0035] The drain filter frame 11 is used to automatically form a drain effect when too much impurities are attached to the water.

[0036] It can be understood that the utility model can collect the falling water and separate the impurities therein in the first place to prevent the impurities from entering the return water pipeline to form dirt and corrode the pipeline, and centrally store the separated impurities to facilitate subsequent centralized cleaning and use.

[0037] A specific application of the operation process of this embodiment is as follows: when in use, first use the water collecting tray 2 to receive the falling water, and guide it inward and concentrate it, and then guide it to the central area inside the inner drainage pipe 4, and the impurities contained therein are filtered by the conical filter frame 7 at the first time, so that the impurities are separated and stored above the guide platform 12. At this time, the water continues to flow down to flush the impurities on the surface of the conical filter frame 7 to make it slide outward. After flowing down, the water is stored between the partition 5 and the bottom plate 6 to form secondary precipitation, and finally the water is directly pumped out through the pumping pipe 9; at the same time, the impurities located inside the guide platform 12 are guided downward by its tilting mechanism, and flow into the storage tank 13 through the transfer pipe 14 for storage. At this time, the water containing impurities will overflow through the drain filter frame 11, and the impurities will be discharged regularly after being stored to a certain amount. After this arrangement, impurities can be effectively prevented from remaining in the drainage pipeline for a long time, so as to prevent the formation of dirt and corrosion of the pipeline, thereby improving the use effect of the equipment.
