Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary structures for cooling tower sewage discharge, and in particular to an auxiliary sewage discharge structure for cooling towers. Background Technology

[0002] Cooling tower blowdown is a crucial part of industrial circulating water systems. It aims to maintain stable circulating water quality by regularly discharging water containing high concentrations of impurities, preventing scaling, corrosion, and biological contamination of equipment, thereby ensuring efficient operation of the cooling tower and extending equipment life.

[0003] The lack of a filtration auxiliary structure below the condensate layer in existing cooling towers makes it easy for the cooled water to form scale, which is difficult to clean and maintain later, increasing the difficulty of sewage discharge. Therefore, it is particularly important to design an auxiliary sewage discharge structure for cooling towers to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing cooling towers do not have a filter auxiliary structure below the condensate layer, which makes the cooled water prone to forming dirt, difficult to clean and maintain, and increases the difficulty of sewage discharge. Therefore, this invention proposes an auxiliary sewage discharge structure for cooling towers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cooling tower auxiliary sewage discharge structure, comprising a tower body, an opening at the top of the tower body, a support on the opening, a motor mounted on the support, a rotatable fan blade mounted at the output end of the motor, a spray pipe mounted below the fan blade, nozzles evenly distributed at the bottom of the spray pipe, high-temperature water being transported through an auxiliary pipe to the spray pipe, a condensation layer being installed below the spray pipe, an air inlet on the left side wall of the tower body, and a connecting pipe being installed on the right side wall of the tower body, the connecting pipe being used to transport low-temperature water.

[0006] Preferably, the air inlet is located below the condensation layer, a detachable frame is installed below the condensation layer, a stainless steel filter screen is installed in the frame, and positioning plates are symmetrically distributed on the inner wall of the tower body, with the frame abutting against the positioning plates.

[0007] Preferably, the left end of the frame is connected to the tower body by bolts and threads, and the right side of the frame is provided with an opening on the tower body. A rotatable cover plate is installed at the opening by a hinge structure. The lower end of the cover plate is the hinge rotation point, and the upper end of the cover plate is installed on the tower body by fasteners. The opening is located above the connecting pipe.

[0008] Preferably, a discharge port is installed at the bottom of the tower body, and a shut-off valve is installed on the discharge port.

[0009] Preferably, an inspection port is provided on the right side of the discharge port on the tower body, and a baffle is installed on the inspection port by fasteners, and a handle is installed on the baffle.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the condensed water is filtered through a frame and stainless steel filter screen structure. Specifically, an auxiliary pipe supplies high-temperature water to the spray pipe, which is then sprayed out through nozzles and acts on the condensation layer. This condensation layer is permeable, allowing the water to pass smoothly and reach the frame. At this point, the stainless steel filter screen in the frame plays a crucial role, effectively filtering out dirt from the water and reducing the amount of dirt entering subsequent systems, thus lowering the risk of blockage. The filtered water is then transported to the discharge port, ensuring water cleanliness and smooth drainage. An inspection port structure is also installed on the right side of the discharge port for easy maintenance. Compared to conventional drainage structures, the technical solution adopted in this utility model can filter the condensed water from the tower, reducing dirt formation and alleviating the burden of drainage. The overall structure is compact, the spatial layout is reasonable, and it is easy to install and maintain. It solves the problem in existing cooling towers where the lack of a filter auxiliary structure below the condensation layer leads to dirt formation in the cooled water, making subsequent cleaning and maintenance difficult and increasing the difficulty of drainage.

[0011] 2. In this utility model, the sewage discharge process can be easily controlled through the designed discharge port and shut-off valve. When sewage discharge is required, the shut-off valve is opened, and dirt and water can be discharged from the discharge port. After sewage discharge is completed, the shut-off valve is closed to ensure the airtightness of the cooling tower and prevent external impurities from entering. Attached Figure Description

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0015] This utility model provides an auxiliary sewage discharge structure for a cooling tower, including a tower body 1. The top of the tower body 1 has an opening 504, and a support 101 is mounted on the opening 504. A motor 102 is mounted on the support 101, and a rotatable fan blade 103 is mounted at the output end of the motor 102. A spray pipe 2 is mounted below the fan blade 103, and nozzles 201 are evenly distributed at the bottom of the spray pipe 2. High-temperature water is transported through the spray pipe 2 via an auxiliary pipe 202. A condensation layer 3 is installed below the spray pipe 2. An air inlet 4 is provided on the left side wall of the tower body 1, and a connecting pipe 401 is installed on the right side wall of the tower body 1. The connecting pipe 401 transports low-temperature water. The air inlet 4 is located below the condensation layer 3, and a detachable frame 5 is installed below the condensation layer 3. The frame 5 houses... The cooling tower includes a stainless steel filter screen 501. Positioning plates 502 are symmetrically distributed on the inner wall of the tower body 1. The frame 5 abuts against the positioning plates 502. The left end of the frame 5 is threadedly connected to the tower body 1 via bolts 503. An opening 504 is provided on the right side of the frame 5 on the tower body 1. A rotatable cover plate 505 is installed at the opening 504 via a hinge structure. The lower end of the cover plate 505 is a hinge rotation point 506, and the upper end of the cover plate 505 is installed on the tower body 1 via fasteners. The opening 504 is located above the connecting pipe 401. The stainless steel filter screen 501 filters the cooled water, effectively preventing the formation of dirt. The frame 5 is detachable, facilitating cleaning and maintenance of the stainless steel filter screen 501 and reducing the difficulty of sewage discharge. Furthermore, the rotatable fan blades 103 increase airflow within the cooling tower, improving cooling efficiency. The shut-off valve 508 installed on the discharge port 507 can easily control the sewage discharge process, ensuring the accuracy and safety of sewage discharge. The inspection port 6 facilitates the inspection and maintenance of the cooling tower's interior, improving equipment reliability and extending its service life.

[0016] In actual use, the auxiliary sewage discharge structure of the cooling tower includes a frame 5 below the condensation layer 3. A stainless steel filter screen 501 is fixedly connected within the frame 5. High-temperature water is supplied from the auxiliary pipe 202 to the spray pipe 2 and finally sprayed out through multiple nozzles 201, directly acting on the condensation layer 3. The condensation layer 3 is a permeable layer. The water treated by the condensation layer 3 reaches the frame 5, where the stainless steel filter screen 501 filters the condensed water before it is discharged to the outlet 507. This filtering process removes some of the dirt from the water, reducing the risk of blockage. The frame 5 is located within the tower body 1. For the fixing work, a set of positioning plates 502 structures are prefabricated in the tower body 1. After the frame 5 is installed, the workers manually screw in bolts 503 to limit the frame 5 in the tower body 1. An opening 504 structure is set on the right side of the tower body 1, and a cover plate 505 structure is installed at the opening 504 to facilitate the workers' installation of the frame 5 structure. Driven by the motor 102, the fan blades 103 form airflow inside the tower body 1, and combine with the air inlet 4 to form convection, which is conducive to the heat exchange work. The condensed water is filtered through the frame 5 and the stainless steel filter screen 501 structure. Specifically, the auxiliary pipe 202 delivers high-temperature water to the spray pipe 2. The high-temperature water is sprayed out through the nozzle 201 and acts on the condensation layer 3. The condensation layer 3 is a water-permeable layer, allowing the water to pass smoothly and reach the frame 5. At this time, the stainless steel filter screen 501 in the frame 5 plays a key role. It can effectively filter out dirt in the water, reduce the amount of dirt entering the subsequent system, and thus reduce the risk of blockage. The filtered water is then transported to the discharge port 507, ensuring water quality and smooth sewage discharge. An inspection port 6 is also installed on the right side of the discharge port 507, which facilitates maintenance work by staff. Compared with conventional sewage discharge structures, the technical solution adopted by this utility model can filter the water after condensation in the tower body 1, reduce the formation of dirt and reduce the sewage discharge burden. The overall structure is compact, the spatial layout is reasonable, and it is easy to install and maintain.

[0017] Example 1 like Figure 1 As shown, a discharge port 507 is installed at the bottom of the tower body 1, and a shut-off valve 508 is installed on the discharge port 507. An inspection port 6 is located on the right side of the discharge port 507 on the tower body 1. A baffle 601 is installed on the inspection port 6 via fasteners, and a handle 602 is installed on the baffle 601. The overall effect of Embodiment 1 is that, during use, the drainage process can be easily controlled through the provided discharge port 507 and shut-off valve 508. When drainage is required, the shut-off valve 508 is opened, allowing dirt and water to be discharged from the discharge port 507. After drainage is completed, the shut-off valve 508 is closed to ensure the airtightness of the cooling tower and prevent external impurities from entering.

[0018] Working principle: A frame structure is set below the condensation layer, and a stainless steel filter screen is fixedly connected in the frame. Auxiliary pipes deliver high-temperature water to the spray pipes, which is then sprayed out through multiple sets of nozzles, directly acting on the condensation layer. The condensation layer is a permeable layer. The water treated by the condensation layer reaches the frame, where the stainless steel filter screen filters the condensed water before it is sent to the discharge port. This filters out some of the dirt in the water, reducing the risk of blockage. The frame is fixed in the tower body by a set of prefabricated positioning plates. After the frame is installed, the bolts are manually tightened to limit the frame in the tower body. An opening structure is set on the right side of the tower body, and a cover plate structure is installed at the opening to facilitate the installation of the frame structure. Driven by a motor, the fan blades create airflow inside the tower body, which, combined with the air inlet, forms convection, which is conducive to heat exchange.
