Description

Technical Field

[0001] This utility model relates to the field of spiral coil condenser technology, specifically an energy-saving spiral coil condenser device. Background Technology

[0002] In energy-intensive fields such as chemical engineering, energy, and refrigeration, condensers are key equipment for heat exchange, and their performance directly affects system energy efficiency and operating costs.

[0003] Traditional spiral coil condensers have shortcomings in airflow guidance. When gas enters the condenser tube, a central jet effect easily occurs, with a large amount of gas concentrating in the center of the tube, making it difficult to fully contact the tube wall. This results in the difficulty in breaking down the gas film thermal resistance on the tube wall, limiting the overall heat transfer coefficient and increasing the energy consumption of equipment such as compressors and circulating pumps. At the same time, uneven airflow scouring of the tube wall can easily cause localized damage due to high-speed airflow impact and scaling corrosion, shortening the service life of the equipment. Therefore, there is an urgent need for an energy-saving spiral coil condenser device to solve the above problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 - Figure 3 The present invention provides an energy-saving spiral coil condenser device, including a fixing frame 1, wherein a spiral condenser tube 2 is fixedly connected inside the fixing frame 1, and further comprising:

[0021] A flow guiding component, disposed on the inner wall of the spiral condenser 2, is used to guide the gas entering the spiral condenser 2.

[0022] A diffusion assembly is disposed on the inner wall of the spiral condenser tube 2 and is used to diffuse the gas entering the spiral condenser tube 2.

[0023] The flow guiding components facilitate the flow of gas entering the spiral condenser 2, thereby preventing the central jet effect from occurring when the airflow enters the spiral condenser 2 and disrupting the thermal resistance of the gas film on the tube wall. The diffusion components facilitate the further diffusing and guiding of the airflow entering the spiral condenser 2, thereby improving the uniformity of the airflow after entering the spiral condenser 2, increasing the heat transfer coefficient, and reducing overall energy consumption.

[0024] Furthermore, the flow guiding assembly includes a fixed pipe 301, which is disposed on the inner wall of the spiral condenser 2. A connecting frame 302 is fixedly connected to the inner wall of the fixed pipe 301, and a flow guiding head 303 is fixedly connected to the side wall of the connecting frame 302. The flow guiding head 303 is inverted conical in shape. A clearance groove 304 is formed on the inner wall of the spiral condenser 2, and the fixed pipe 301 is disposed on the inner wall of the clearance groove 304. The inner diameter of the fixed pipe 301 matches the inner diameter of the spiral condenser 2. Through the configured flow guiding assembly, the airflow is directed to enter the interior of the spiral condenser 2. The airflow impacts the surface of the guide head 303, which is an inverted cone shape. This allows the airflow impacting the surface of the guide head 303 to diffuse in all directions, thus facilitating the guidance of the gas entering the spiral condenser 2. This prevents the airflow from exhibiting a central jet effect when entering the spiral condenser 2, which would damage the thermal resistance of the gas film on the tube wall. The recessed groove 304 facilitates the embedding of the fixed tube 301 into the recessed groove 304, achieving concentricity between the fixed tube 301 and the spiral condenser 2, thereby avoiding any impact on the airflow.

[0025] Furthermore, the diffusion assembly includes a diffusion plate 401, which is fixedly connected to the inner wall of the fixed tube 301. One end of the diffusion plate 401 is provided with multiple guide holes 402. Through the provided diffusion assembly, the airflow after passing through the surface of the guide head 303 impacts one end of the diffusion plate 401 and passes through the multiple guide holes 402 provided at one end of the diffusion plate 401. The guiding angle of the multiple guide holes 402 is inclined and diffused from the center to the surrounding area. When the airflow passes through the multiple guide holes 402, it is guided and diffused, thereby improving the uniformity of the airflow after entering the spiral condenser tube 2, increasing the heat transfer coefficient, and reducing the overall energy consumption.

[0026] Furthermore, the inner wall of the spiral condenser tube 2 is provided with an adsorption component, which includes a magnetic ring 501. The magnetic ring 501 is disposed on the inner wall of the spiral condenser tube 2, and an installation groove 502 is opened on the inner wall of the spiral condenser tube 2. The magnetic ring 501 is fixedly connected to the inner wall of the installation groove 502. Through the adsorption component, it is easy to quickly connect the fixed tube 301 and the spiral condenser tube 2, thereby improving the efficiency of installing and fixing the flow guiding component and the diffusion component to the spiral condenser tube 2, and improving the convenience of the overall renovation of the old spiral coil condenser.

[0027] It should be noted that: one end of the spiral condenser tube 2 is provided with an embedding groove 503, and the side wall of the fixing tube 301 abuts against the inner wall of the embedding groove 503. The fixing tube 301 is made of ferritic stainless steel. Through the embedded groove 503, when the fixing tube 301 is installed, it is embedded in the inner wall of the embedding groove 503, so that one end of the fixing tube 301 and one end of the spiral condenser tube 2 are kept at the same level, thereby avoiding the impact on the connection between the fixing bracket 1 and the external pipe. At the same time, the embedded groove 503 can also limit the fixing tube 301, improving the stability of the fixing between the fixing tube 301 and the spiral condenser tube 2. Secondly, the mounting groove 502 made of ferritic stainless steel is prone to forming a dense chromium oxide protective film on its surface during use due to the presence of chromium, thereby improving the overall corrosion resistance of the magnetic ring 501 and increasing its service life while meeting the requirements of stable adsorption.

[0028] Working principle: During use, the flow guiding component causes the airflow to impact the surface of the flow guiding head 303 when it enters the spiral condenser tube 2. The flow guiding head 303 is inverted conical, which causes the airflow impacting the surface of the flow guiding head 303 to diffuse in all directions. This facilitates the guidance of the gas entering the spiral condenser tube 2 and avoids the central jet effect when the airflow enters the spiral condenser tube 2, which would damage the gas film thermal resistance of the tube wall. The recessed groove 304 makes it easy to embed the fixed tube 301 into the recessed groove 304 to achieve concentricity between the fixed tube 301 and the spiral condenser tube 2, thereby avoiding any impact on the airflow.

[0029] Meanwhile, the flow guiding component ensures that the airflow impacts the surface of the flow guiding head 303 when it enters the spiral condenser tube 2. The flow guiding head 303 is inverted conical, which allows the airflow impacting the surface of the flow guiding head 303 to diffuse in all directions. This facilitates the guidance of the gas entering the spiral condenser tube 2 and prevents the airflow from having a central jet effect when entering the spiral condenser tube 2, which would damage the thermal resistance of the tube wall gas film. The recessed groove 304 makes it easy to embed the fixed tube 301 into the recessed groove 304 to achieve concentricity between the fixed tube 301 and the spiral condenser tube 2, thereby avoiding any impact on the airflow.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
