Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cooling tower equipment, in particular to a novel high-efficiency cooling filler. Background Art
[0002] There are circulating water fields in oil refining and chemical enterprises. The circulating water is mainly cooled by cooling towers. The main cooling process of the cooling tower occurs in the filler area. The circulating hot water flows from top to bottom in the form of a film on the filler, and the air flows from bottom to top. The circulating hot water is cooled by countercurrent contact. Most of the existing cooling fillers still use the most primitive film flow method, but the filler surface is smooth and the water flow rate is too fast. There is not enough cooling time for the circulating hot water, so the best cooling effect is not achieved. At present, some new fillers that can extend the residence time of circulating water are available, but most of them are PVC, which are integrated by contact and bonding with each other. In order to achieve good fixation, there are many bonding points. Although this prolongs the residence time of circulating water on the filler, the bonding part hinders the flow of circulating water, causing the part to be easily scaled or blocked, which is becoming more and more serious. The water film slowly turns into water flow, which still cannot achieve a good cooling effect. Moreover, the service life of PVC fillers is mostly 5-7 years. After long-term use, it is very easy to be damaged. The damaged filler falls into the circulating water and is easily brought into the heat exchanger to cause blockage. This phenomenon is most serious when the old is replaced with the new. Therefore, it is necessary to develop a new type of filler with good cooling effect, long service life and not easy to break. Utility Model Content
[0003] The purpose of the utility model is to overcome the shortcomings of the prior art, improve the cooling effect of circulating water cooling filler, extend the service life of the filler, and prevent damage to the filler during the inspection and maintenance process. The utility model provides a new type of high-efficiency cooling filler.
[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a new type of high-efficiency cooling filler, including a frame and a fin tube box, the fin tube box is divided into two groups, an upper group and an lower group, the fin tube box is connected to fins, the fins cover the entire fin tube box, the frame is fixed on the outer periphery of the fins, and the front and rear ends of the fin tube box are respectively provided with a connecting inlet and a connecting outlet.
[0005] Furthermore, the fin is a broken line structure.
[0006] Furthermore, the fins are provided with concave-convex patterns.
[0007] Furthermore, the concave-convex patterns are in a right-angled trapezoidal structure.
[0008] Furthermore, the frame is made of fiberglass.
[0009] Furthermore, the medium in the fin tube box is a refrigerant.
[0010] Beneficial effects of the utility model:
[0011] (1) The medium in the fin tube box is a refrigerant with a very low boiling point (such as Freon, R134a), which is connected to the compressor to provide refrigeration. The low temperature is transmitted to the fins, and the fins are in contact with the circulating hot water over a large area, which greatly improves the cooling effect of the circulating hot water and improves the product yield. In addition, the fins are provided with concave and convex patterns, which are in a right-angled trapezoidal structure. The circulating hot water flows from top to bottom on the fin packing through the concave and convex patterns in a film manner, which prolongs the residence time of water on the packing. The fins do not contact each other, which is not easy to cause blockage. It is firm and reliable and can be used safely for a long period of time.
[0012] (2) The FRP frame strengthens the stability of the fins and protects the filler from being bumped or damaged during installation, inspection and maintenance. Even if it is replaced, the old filler will not fall into the circulating water.
[0013] (3) The fin tube box is divided into two groups, one for use and one for backup. If there is a leak in the fin tube box, it needs to be dealt with in time. The leaking fin tube box can be short-circuited in a short time and then repaired or replaced during maintenance.
[0014] (4) The cooling filler of the utility model is suitable for all circulating water cooling towers, has a wide range of applications, a long service life, is safe and reliable, has strong overall firmness, and can be removed and replaced without worries. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Example:
[0020] like Figures 1 to 3 As shown, a new type of high-efficiency cooling filler includes a frame 1 and a fin tube box 2. The fin tube box 2 is divided into two groups, an upper group and an lower group. The fin tube box 2 is connected with fins 5, and the fins 5 cover the entire fin tube box 2. The frame 1 is fixed on the outer periphery of the fins 5. The front and rear ends of the fin tube box 2 are respectively provided with a connecting inlet 3 and a connecting outlet 4.
[0021] Preferably, in this embodiment, the fin 5 has a zigzag structure.
[0022] Preferably, in this embodiment, the fin 5 is provided with concave and convex patterns.
[0023] Preferably, in this embodiment, the concave and convex patterns have a right trapezoidal structure.
[0024] Preferably, in this embodiment, the frame 1 is made of fiberglass.
[0025] Preferably, in this embodiment, the medium in the finned tube header 2 is a refrigerant.
[0026] During use, multiple temperature-reducing fillers of the present utility model are interconnected with each other by short circuits through the connection inlet 3 and the connection outlet 4 on the finned tube header 2. After testing for airtightness and no leakage, start the compressor for refrigeration. The finned tube header 2 conducts low temperature to the fin 5, and a large amount of circulating hot water contacts the fin 5 after falling onto the fin 5 to reduce the temperature. The power of the compressor can be adjusted at any time according to production requirements to reduce the circulating hot water to the temperature that meets the device requirements.
[0027] There are two sets of upper and lower finned tube headers 2. According to requirements, one can be used as a standby. In summer when the temperature is high, it depends on the situation whether all are put into use. Normally, if one set leaks or fails, it can be directly switched to the other set for use, and then the leaking finned tube header 2 can be bypassed through a short circuit. It can be replaced or repaired during maintenance without affecting the normal use of the filler.
[0028] The above-described embodiments are only preferred solutions of the present utility model, and do not impose any form of limitation on the present utility model. There are other variations and modifications without exceeding the technical solutions recorded in the claims.
[0029] In the description of the present utility model, it should be understood that the terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
