Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower nozzles, in particular to a cooling tower nozzle with uniform water outlet. Background Technique

[0002] A cooling tower is a device that exchanges heat through heat transfer. Using water as a circulating coolant, it absorbs heat from a system and discharges it into the atmosphere. Heat and cold exchange generate steam, and the evaporation of the steam takes away heat to achieve evaporation heat dissipation, convective heat transfer, and radiative heat transfer. Principles such as these are used to dissipate the waste heat generated in industry or refrigeration and air conditioning, and then reduce the water temperature of the evaporation heat dissipation device to ensure the normal operation of the equipment system.

[0003] As one of the important components of the cooling tower, the existing nozzles have problems such as easy displacement when the water pressure is large, easy leakage of the seal, and uneven water outlet, which will affect the spraying effect and reduce the working efficiency of the cooling tower. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cooling tower nozzle with uniform water outlet to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A cooling tower nozzle with uniform water outlet includes a nozzle connecting pipe. One end of the nozzle connecting pipe is connected with a buffer pipe, and a nozzle body is arranged at the end of the buffer pipe far away from the nozzle connecting pipe.

[0007] The diameter of the buffer pipe gradually increases from the middle to both ends. The diameter of the nozzle connecting pipe is smaller than the maximum diameter of the buffer pipe and larger than the minimum diameter of the buffer pipe. The nozzle body includes an intermediate nozzle body located in the middle of the buffer pipe and an outer nozzle body located outside the intermediate nozzle body.

[0008] By setting a buffer pipe with a variable diameter, when the circulating water flows through the narrow middle position, it can reduce the water pressure and increase the water speed to ensure the stability of the water speed and water pressure.

[0009] As a further scheme of the utility model: the buffer pipe includes a first buffer pipe and a second buffer pipe. The first buffer pipe and the second buffer pipe are fixedly connected, and the connection part of the first buffer pipe and the second buffer pipe is the minimum diameter part of the buffer pipe.

[0010] By setting the first buffer pipe and the second buffer pipe, and then fixedly connecting the buffer pipes by welding, the overall processing difficulty and processing cost are reduced.

[0011] As a further scheme of the utility model: one end of the first buffer pipe far away from the second buffer pipe is connected with the nozzle connecting pipe.

[0012] The first buffer pipe is communicated with the nozzle connecting pipe and is used to introduce the liquid in the nozzle connecting pipe into the buffer pipe and then spray it through the nozzle.

[0013] As a further solution of the present utility model: the nozzle connecting pipe is provided with an external connecting thread, and one end of the first buffer pipe far from the second buffer pipe is provided with an internal connecting thread. The nozzle connecting pipe and the first buffer pipe are fixedly connected by threads.

[0014] The nozzle connecting pipe is fixedly connected to the first buffer pipe by threads, which reduces the connection difficulty.

[0015] As a further solution of the present utility model: an annular gasket is sleeved on the first buffer pipe. One end of the annular gasket abuts against the end of the nozzle connecting pipe, and the other end of the annular gasket is pressed by a connecting nut. The connecting nut is threadedly connected to the first buffer pipe. The annular gasket is sleeved at the connection between the first buffer pipe and the nozzle connecting pipe.

[0016] An annular gasket is sleeved at the connection between the first buffer pipe and the nozzle connecting pipe, and the annular gasket is pressed at the connection by a connecting nut, which can effectively improve the sealing effect and avoid the occurrence of displacement problems when the water pressure of the nozzle is relatively large.

[0017] As a further solution of the present utility model: the first buffer pipe is of an inverted frustum structure, and the second buffer pipe is of a regular frustum structure.

[0018] The buffer pipe with a frustum structure is simple to process and has a low cost.

[0019] As a further solution of the present utility model: the middle nozzle body and the buffer pipe are coaxially arranged, and there are four outer nozzle bodies. The four outer nozzle bodies are all arranged outside the middle nozzle body.

[0020] By arranging the middle nozzle and the outer nozzles, the spraying of the nozzles can be made uniform.

[0021] As a further solution of the present utility model: the connection between the outer nozzle body and the second buffer pipe is located at half of the aperture of the water outlet end of the second buffer pipe, and the outer nozzle body is arranged to incline outward.

[0022] By arranging the outer nozzles at half of the aperture and arranging the nozzles obliquely, the water inlet pressure of the nozzles can be made uniform, the difference in water inlet pressure between the nozzles is small, and the spraying of each nozzle is relatively uniform.

[0023] As a further solution of the present utility model: a plurality of spray holes are evenly arranged on the nozzle body. By providing a plurality of spray holes, the uniformity and stability of the water outlet of the nozzle can be better ensured.

[0024] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0025] 1. The nozzle of this application is provided with a frustum-shaped buffer groove, which has a structure that is large at both ends and small in the middle. When the circulating water flows through the narrow middle position, it can reduce the pressure and increase the speed of the water flow to ensure the stability of the water speed and water pressure.

[0026] 2. Uniform circular grid-shaped nozzles are arranged on the nozzle body of this application, which can better ensure the uniformity and stability of the water output of the nozzle.

[0027] 3. The connecting pipe of the nozzle of this application is in the form of an external thread and is threadedly connected with the external circulating water pipe, and a ring gasket and a nut are connected at the rear end for fixation, effectively improving the sealing performance of the connection and avoiding the occurrence of displacement problems when the water pressure of the nozzle is relatively large.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Please refer to Figures 1-3 , in the embodiment of the present utility model, a cooling tower nozzle with uniform water output includes a nozzle connecting pipe 1. One end of the nozzle connecting pipe 1 is connected with a buffer pipe, and a nozzle body 5 is arranged at the end of the buffer pipe away from the nozzle connecting pipe 1.

[0034] The diameter of the buffer pipe gradually increases from the middle to both ends. The diameter of the nozzle connecting pipe 1 is smaller than the maximum diameter of the buffer pipe and larger than the minimum diameter of the buffer pipe. The nozzle body 5 includes an intermediate nozzle body located in the middle of the buffer pipe and an outer nozzle body located outside the intermediate nozzle body. By setting a buffer pipe with a variable diameter, when the circulating water flows through the narrow middle position, it can reduce the pressure and increase the speed of the water flow to ensure the stability of the water speed and water pressure.

[0035] In this embodiment, the buffer pipe includes a first buffer pipe 3 and a second buffer pipe 4. The first buffer pipe 3 is fixedly connected to the second buffer pipe 4. The first buffer pipe 3 has an inverted frustum structure, and the second buffer pipe 4 has a regular frustum structure. That is, the connection part between the first buffer pipe 3 and the second buffer pipe 4 is the smallest diameter part of the buffer pipe. By setting the first buffer pipe 3 and the second buffer pipe 4 and then fixedly connecting the buffer pipes through welding, the difficulty and cost of overall processing are reduced.

[0036] One end of the first buffer pipe 3 far from the second buffer pipe 4 is connected to the nozzle connecting pipe 1. The first buffer pipe 3 is communicated with the nozzle connecting pipe 1 and is used to introduce the liquid in the nozzle connecting pipe into the buffer pipe and then spray it through the nozzle. The nozzle connecting pipe 1 is provided with an external connecting thread, and one end of the first buffer pipe 3 far from the second buffer pipe 4 is provided with an internal connecting thread. The nozzle connecting pipe 1 is fixedly connected to the first buffer pipe 3 through a thread. The nozzle connecting pipe 1 is fixedly connected to the first buffer pipe 3 through a thread, which reduces the connection difficulty. An annular gasket 2 is sleeved on the first buffer pipe 3. One end of the annular gasket 2 abuts against the end of the nozzle connecting pipe 1, and the other end of the annular gasket 2 is pressed by a connecting nut 6. The connecting nut 6 is threadedly connected to the first buffer pipe 3. The annular gasket 2 is sleeved at the connection part between the first buffer pipe 3 and the nozzle connecting pipe 1. An annular gasket 2 is sleeved at the connection part between the first buffer pipe 3 and the nozzle connecting pipe 1, and the annular gasket 2 is pressed at the connection part by the connecting nut 6, which can effectively improve the sealing effect and avoid the occurrence of displacement problems when the water pressure of the nozzle is relatively large.

[0037] The middle nozzle body and the buffer pipe are coaxially arranged. There are four peripheral nozzle bodies, and the four peripheral nozzle bodies are all arranged outside the middle nozzle body. The connection part between the peripheral nozzle body and the second buffer pipe 4 is located at half of the aperture of the water outlet end of the second buffer pipe 4. The peripheral nozzle body is arranged obliquely outward. By arranging the middle nozzle and the peripheral nozzles, the spraying of the nozzles can be made uniform, and the inclined arrangement of the nozzles can make the water inlet pressure of the nozzles uniform, with a small difference in water inlet pressure between the nozzles, and the spraying of each nozzle is relatively uniform. In addition, a plurality of spray openings 51 are uniformly arranged on the nozzle body 5. By setting a plurality of spray openings, the uniformity and stability of the water outlet of the nozzle can be better ensured.

[0038] When the utility model is in use, the nozzle connecting pipe 1 is connected to the water supply pipeline, and the cooling water is introduced from the water supply pipeline into the buffer pipe. Since the buffer pipe has a variable diameter structure and is narrow in the middle and wide at both ends, when the cooling water enters the buffer pipe from the nozzle connecting pipe 1, it will pass through the change of the aperture. When the cooling water flows through the narrow middle position, it can reduce the pressure and increase the speed of the water flow to ensure the stability of the water speed and water pressure. Then the cooling water enters the nozzle body through the buffer pipe and is sprayed out through the spray openings on the nozzle, and then is cooled in the cooling tower.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
