Abstract
Description
Technical Field
[0001] This utility model relates to the field of evaporative condenser technology, and in particular to a uniformly distributed spray manifold. Background Technology
[0002] Evaporative condensers are core heat exchange equipment in industrial refrigeration and air conditioning systems. Their working principle involves uniformly spraying cooling water onto the surface of the heat exchange coils through a spray manifold, utilizing the heat absorption of water evaporation to achieve refrigerant condensation within the coils. Furthermore, in chemical and food processing industries, spray manifolds are also necessary to ensure precise and uniform distribution of the medium to guarantee reaction efficiency or processing quality. Existing spray manifold technologies present the following key problems in these scenarios:
[0003] Inconsistent nozzle height leads to uneven heat exchange in evaporative condensers: Evaporative condensers typically have long spray manifolds, and existing nozzles often use simple insertion or threaded connections without precise positioning structures. This results in nozzles at different locations extending 3-5mm into the manifold. When cooling water flows within the manifold, nozzles closer to the inlet contact the water flow first, resulting in a larger flow rate, while nozzles farther from the inlet produce water later and with a smaller flow rate. This causes uneven cooling water coverage on the heat exchange coil surface, with some areas having excess water and others insufficient water, ultimately leading to a decrease in the overall condensing efficiency of the condenser.
[0004] The turbulent flow of the medium disrupts the uniformity of distribution: Existing manifolds do not have optimized pipe diameters based on medium flow rates, making it easy for cooling water or other media to form turbulence within the pipes, generating eddies and velocity fluctuations, further exacerbating the differences in medium distribution within the manifold. For example, in chemical reaction cooling scenarios, turbulence can lead to insufficient cooling medium supply in some reactor areas, resulting in excessively high local temperatures and affecting the quality of reaction products.
[0005] Poor sealing and adaptability, limiting applicable scenarios: Evaporative condensers are mostly used outdoors or in humid environments. The existing nozzles and manifolds have large connection gaps, which can easily lead to cooling water leakage. Furthermore, the plug seals are unreliable and are prone to corrosion failure after long-term use. At the same time, the existing manifolds are not designed with adaptable structures for different scenarios, resulting in poor versatility and requiring additional customization, which increases the cost of use.
[0006] The aforementioned problems mean that existing spray manifolds cannot meet the high-efficiency heat exchange requirements of evaporative condensers, nor can they be adapted to other scenarios that require uniform distribution. There is an urgent need for a spray manifold with optimized structure, strong adaptability, and uniform distribution. Utility Model Content
[0007] To overcome existing problems, this application provides a uniformly distributed spray manifold, which solves problems such as inconsistent nozzle height, uneven medium flow, and poor sealing in the prior art, and achieves uniform distribution of cooling water or other media along the entire length of the manifold, thereby improving heat exchange efficiency and system reliability.
[0008] The technical solution adopted by the embodiments of this application to solve its technical problem is:
[0009] A uniformly distributed sprinkler manifold includes a manifold body and a plurality of sprinklers installed at the lower part of the manifold body. One end of the manifold body is provided with a water inlet and the other end is provided with a plug. Connection holes are provided at the intersections of the manifold body and the plurality of sprinklers. The sprinklers are provided with extension tubes at the installation locations of the connection holes. Two locking blocks are symmetrically provided at the ends of the extension tubes. The connection holes and the symmetrically arranged locking blocks are provided with locking grooves at corresponding positions. The locking blocks and locking grooves cooperate to limit the installation of the sprinklers.
[0010] Preferably, a sealing ring is provided between the extension tube and the connection hole to prevent media leakage.
[0011] Preferably, a sealing gasket is provided between the nozzle and the manifold body to enhance the sealing performance at the connection.
[0012] Preferably, the inner diameter of the manifold body is optimized according to the medium flow rate, so that the medium flows in a laminar state inside the pipe.
[0013] Preferably, the engaging structure of the card block and the card slot includes a limiting block for limiting the position of the nozzle when the nozzle is connected to the manifold body.
[0014] Preferably, the nozzle has an internal atomizing structure for atomizing and uniformly spraying cooling water.
[0015] Preferably, the plug and the manifold body are connected in a sealed manner to prevent media leakage.
[0016] Preferably, both the manifold body and the nozzle are made of corrosion-resistant materials, making them suitable for humid or corrosive environments.
[0017] The advantages of the embodiments of this application are:
[0018] By combining the extension tubes of uniform height with the synchronously rising liquid level, the design ensures that the outflow starting point and initial conditions of all nozzles are consistent in principle. This allows the cooling water to evenly cover the entire heat exchange surface of the evaporative condenser, avoiding local dry spots or overcooling and significantly improving condensation efficiency.
[0019] The dual-sealing structure, consisting of a sealing ring and a sealing gasket, effectively solves the leakage problem at traditional connections. This not only prevents water waste and environmental pollution, but more importantly, it eliminates scaling and corrosion on the outside of the manifold and erosion of other equipment components caused by leakage, significantly extending the service life of the entire system. Its excellent sealing performance also allows it to adapt to harsh working conditions such as high humidity and high corrosiveness, broadening its application scenarios.
[0020] The plug-in limiting structure of the locking blocks, slots, and limit blocks allows for easy nozzle installation without the need for precision tools or complex adjustments. Simply inserting and rotating the nozzle at a certain angle achieves quick positioning and locking, greatly simplifying installation and subsequent maintenance. This modular and standardized design also enhances the product's versatility and interchangeability, allowing users to flexibly configure the number and spacing of nozzles according to different needs, reducing the time and cost of non-standard customization.

By combining the design of an extension pipe of uniform height with a synchronously rising liquid surface, it ensures in principle that the outflow starting point and initial conditions of all nozzles are consistent.

[0033] The technical solution in this application is to solve the above problems, and the overall approach is as follows:
[0034] Example
[0035] This embodiment provides a specific structure for a uniformly distributed spray manifold, such as... Figure 1-6 As shown, it includes a manifold body 1 and several nozzles 2 installed at the lower part of the manifold body 1. One end of the manifold body 1 is provided with a water inlet 3 and the other end is provided with a plug 4. The plug 4 and the manifold body 1 are sealed together to prevent the medium from leaking out. Connection holes 5 are provided at the intersection of the manifold body 1 and the several nozzles 2.
[0036] Furthermore, the main body 1 of the manifold is in the shape of a long pipe, with an inlet 3 at one end for connecting to an external water supply pipeline, and a plug 4 installed at the other end by means of threaded connection or interference fit. The plug 4 and the end joint surface of the main body 1 of the manifold are provided with a sealing structure to form a reliable sealing connection and effectively prevent the medium from leaking out from the end.
[0037] The nozzle 2 is provided with an extension tube 8 at the installation location of the connection hole 5. Two locking blocks 7 are symmetrically provided at the end of the extension tube 8. The connection hole 5 and the locking blocks 7 are respectively provided with a slot 11. The locking blocks 7 and the slot 11 cooperate to realize the limiting installation of the nozzle 2. The cooperation structure of the locking blocks 7 and the slot 11 includes a limiting block 10, which is used to limit the nozzle 2 when it is connected to the manifold body 1.
[0038] Furthermore, on the pipe wall of the manifold body 1, a connecting hole 5 is provided at a position corresponding to the preset installation position of each nozzle 2. The top of the nozzle 2 is provided with an integrally formed extension tube 8, which is used to insert into the connecting hole 5 of the manifold body 1. In order to achieve quick installation and reliable positioning of the nozzle 2, two radially outward protruding locking blocks 7 are symmetrically provided on the outer wall of the end of the extension tube 8. Correspondingly, on the inner circumference of the connecting hole 5, two slots 11 are provided to accommodate the locking blocks 7 at positions corresponding to the symmetrical locking blocks 7. During installation, the extension tube 8 of the nozzle 2 is aligned with the connecting hole 5, and the two locking blocks 7 are aligned with the entrance of the slot 11. After insertion, a certain angle is rotated to allow the locking blocks 7 to slide into the locking position of the slot 11, thereby achieving circumferential and axial positioning of the nozzle 2 on the manifold body 1.
[0039] A sealing ring 9 is provided between the extension tube 8 and the connection hole 5 to prevent media leakage, and a sealing gasket 6 is provided between the nozzle 2 and the main body of the manifold 1 to enhance the sealing performance of the connection.
[0040] Furthermore, a sealing ring 9 is fitted between the outer wall of the extension pipe 8 and the inner wall of the connecting hole 5. This sealing ring 9 is compressed between the two, forming a first reliable static seal, primarily preventing leakage of the medium within the manifold body 1 from the connection gap. In addition, an annular sealing gasket 6 is pressed between the top shoulder of the nozzle 2 and the outer wall of the manifold body 1. When the nozzle 2 is installed in place via the locking block 7 and the locking groove 11, the top shoulder of the nozzle 2 presses against the sealing gasket 6, forming a second seal, further enhancing the sealing performance at the connection and preventing leakage.
[0041] The inner diameter of the main body of the manifold 1 is optimized according to the medium flow rate, so that the medium flows in a laminar state inside the pipe.
[0042] The nozzle 2 has an internal atomizing structure for atomizing the cooling water and spraying it out evenly.
[0043] Furthermore, when cooling water enters the nozzle 2 from the main body 1 of the manifold, it is broken into fine droplets by the atomizing structure and then evenly sprayed onto the target area to achieve efficient and uniform cooling or humidification.
[0044] Both the main body of the manifold 1 and the nozzle 2 are made of corrosion-resistant materials, making them suitable for humid or corrosive environments to ensure the long service life and reliability of the device.
[0045] The specific work process is as follows:
[0046] Cooling water or other liquid media are injected from the inlet 3 at one end of the manifold body 1. Since the plug 4 at the other end of the manifold body 1 forms a closed environment, the media cannot be discharged from the end and can only accumulate in the pipe. The media moves forward smoothly in the pipe in an almost laminar flow state, avoiding uneven pressure distribution caused by eddies and flow velocity fluctuations.
[0047] As the medium is continuously injected, the liquid level inside the pipe rises synchronously and steadily along the length of the manifold body 1, starting from the inlet 3. The extension tubes 8 of all nozzles 2 extend vertically into the manifold body 1 at the same height. This height is ensured by the precise fit between the locking block 7 and the locking groove 11, guaranteeing that the inlet height of all nozzles 2 is consistent. When the liquid level has not reached the inlet of the extension tube 8, all nozzles 2 are in standby mode, and no medium flows out.
[0048] When the liquid level inside the pipe exceeds the inlet height of the extension pipe 8, all nozzles 2 begin to operate simultaneously under the same static pressure head. Cooling water enters each nozzle 2 simultaneously and uniformly. Since the static pressure conditions at the inlet are exactly the same, the initial flow rate of each nozzle 2 is guaranteed to be consistent. Subsequently, the medium flows through the atomization structure inside the nozzle 2, is broken into fine droplets, and is sprayed out to form a uniform mist field that completely covers the heat exchange coil or other treated surfaces below, thereby achieving efficient and uniform heat exchange or reaction.
[0049] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
