Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a mist-eliminating cooling tower. Background Art

[0002] A cooling tower is a device used to dissipate heat. Its main function is to exchange heat between the cooling water carrying waste heat and the air inside the tower, so that the waste heat is transferred to the air and dissipated into the atmosphere. Cooling towers are usually used to reduce the temperature of circulating cooling water to ensure the normal operation of various industrial equipment and systems. One of the main features of the mist-eliminating cooling tower is that it can effectively reduce or eliminate the white mist phenomenon generated during the cooling process.

[0003] When the demisting cooling tower is in use, the baffle demister inside the tower body is used for demisting work. The airflow is constantly turning between the baffles, and the mist or dust particles will be separated due to inertia during the turning process. In actual applications, the gas flow rate will change. Since the bending area of ​​the baffle on the existing demister is fixed, when the gas flow rate increases, the contact area between the airflow and the baffle is small, resulting in poor demisting effect. When the gas flow rate decreases, the contact area between the airflow and the baffle is large, resulting in an increase in the demisting time. Both of these situations will lead to a decrease in the demisting efficiency of the demister on the demisting cooling tower. Utility Model Content

[0004] The utility model aims to propose a demisting cooling tower to solve the problem that the demisting device in the existing cooling tower cannot adjust the baffle plate according to the change of the air flow rate, thereby causing low demisting efficiency.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technology: a demisting cooling tower, comprising a tower body, a spray assembly is arranged on the tower body, an air inlet is opened near the bottom of the tower body, an induced draft fan is arranged on the top of the tower body, a mounting frame is arranged near the top of the tower body, and a first demisting assembly and a second demisting assembly are detachably mounted on the mounting frame through a mounting port;

[0006] The number of the installation openings is several and they are evenly spaced on the installation frame along the height direction of the tower body, and the first demisting assembly and the second demisting assembly are staggeredly distributed through the installation openings.

[0007] As a further description of the above technical solution: the first mist elimination component includes a first fixed frame, and a plurality of first baffles evenly distributed along the cross-section direction of the tower body are arranged in the first fixed frame.

[0008] As a further description of the above technical solution: the second mist elimination assembly includes a second fixed frame, in which a plurality of second baffles evenly distributed along the cross-section direction of the tower body are arranged;

[0009] The bending directions of the first baffle plate and the second baffle plate are opposite.

[0010] As a further description of the above technical solution: a positioning assembly is provided on both the first fixed frame and the second fixed frame;

[0011] The positioning assembly includes a fixing plate, a plug rod passes through the fixing plate, a limiting plate is arranged on the plug rod, a spring is sleeved on the plug rod at a position between the limiting plate and the fixing plate, and a positioning hole matching with the plug rod is opened on the side wall of the installation opening.

[0012] As a further description of the above technical solution: the first baffle plate and the second baffle plate are both made of stainless steel, and the first baffle plate and the second baffle plate are both in a trapezoidal structure with an open bottom.

[0013] As a further description of the above technical solution: the spray assembly includes a pump body arranged outside the tower body, and the water outlet of the pump body is connected to the spray head arranged inside the tower body through a water supply pipe.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0015] By adjusting the number of the first defogger assembly and the second defogger assembly, the bending area of ​​the baffle on the demister can be changed, so that when the gas flow rate increases, the bending area can be appropriately increased, thereby increasing the contact area between the airflow and the baffle, and when the air flow rate is small, the bending area can be reduced, so that the contact area between the airflow and the baffle becomes smaller, thereby improving the defogger efficiency.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-Figure 7 The present embodiment provides a demisting cooling tower, comprising a tower body 1, a spray assembly 2 is arranged on the tower body 1, an air inlet 3 is opened near the bottom of the tower body 1, an induced draft fan 4 is arranged at the top of the tower body 1, and a mounting frame 5 is arranged near the top of the tower body 1, and a first demisting assembly 6 and a second demisting assembly 7 are detachably mounted on the mounting frame 5 through a mounting port 51;

[0027] There are a plurality of installation openings 51 which are evenly spaced on the installation frame 5 along the height direction of the tower body 1 , and the first demisting components 6 and the second demisting components 7 are staggeredly distributed through the installation openings 51 .

[0028] In the utility model, a corresponding number of first and second demisting assemblies 6 and 7 are selected according to the flow rate of the airflow to be cooled, and then the first and second demisting assemblies 6 and 7 are plugged into the mounting frame 5 through the mounting port 51 to form a demisting device, and then the demisting device is installed inside the tower body 1. When the gas enters the tower body 1 through the air inlet 3 on one side of the tower body 1, the airflow entering the tower body 1 will flow upward due to the induced draft fan 4 on the top of the tower body 1 drawing air outwards, and the spray assembly 2 sprays the coolant and contacts the airflow, and cooperates with the cooling pipe inside the tower body 1 to cool the airflow. The cooled airflow contains mist or dust particles, which will turn in the demisting device and be separated due to inertia, thereby achieving the demisting effect.

[0029] Specifically, refer to Figure 2 and Figure 3 The first demisting assembly 6 includes a first fixed frame 61, and a plurality of first baffles 62 are arranged in the first fixed frame 61 and are evenly distributed along the cross-sectional direction of the tower body 1. The bending portion formed by the first baffle 62 contacts the airflow, and the airflow turns at the bending portion of the first baffle 62. The mist or dust particles are separated due to inertia during the turning process, thereby achieving the demisting effect.

[0030] Specifically, refer to Figure 2-Figure 4 The second demisting assembly 7 includes a second fixed frame 71, in which a plurality of second baffles 72 evenly distributed along the cross-sectional direction of the tower body 1 are arranged. The bending parts formed by the second baffles 72 are used to contact the airflow, and the airflow is turned at the bending parts of the second baffles 72. The mist or dust particles will be separated due to inertia during the turning process, thereby achieving the demisting effect.

[0031] The bending directions of the first baffle 62 and the second baffle 72 are opposite, so that the bending area of ​​the defogger can be increased. When the airflow rate is large, the first baffle 62 and the second baffle 72 cooperate to increase the contact area between the airflow and the baffle, thereby improving the defog efficiency.

[0032] Specifically, refer to Figure 2 , Figure 5 and Figure 7 , the first fixed frame 61 and the second fixed frame 71 are both provided with positioning components 8;

[0033] The positioning assembly 8 includes a fixing plate 81, a plug rod 82 passes through the fixing plate 81, a limiting plate 83 is arranged on the plug rod 82, a spring 84 is sleeved on the plug rod 82 at a position between the limiting plate 83 and the fixing plate 81, and a positioning hole 52 matching with the plug rod 82 is opened on the side wall of the mounting opening 51. When the first mist dispelling assembly 6 and the second mist dispelling assembly 7 are installed, the first fixed frame 61 or the second fixed frame 71 is inserted into the mounting opening 51, and the two plug rods 82 are pulled toward the middle and close together. After the rear end of the first fixed frame 61 or the second fixed frame 71 abuts against the rear end of the mounting frame 5, the plug rod 82 is released, and the plug rod 82 is reset under the action of the spring 84 and inserted into the positioning hole 52 of the mounting frame 5, thereby achieving the fixing of the first mist dispelling assembly 6 and the second mist dispelling assembly 7 on the mounting frame 5.

[0034] It should be noted that the first baffle 62 and the second baffle 72 are both made of stainless steel, and both are in a trapezoidal structure with an open bottom. The baffles made of stainless steel have excellent corrosion resistance and high temperature resistance, and the first baffle 62 and the second baffle 72 with a trapezoidal structure with an open bottom have a bent portion, so that the airflow can be diverted and demisting can be achieved during the diversion process.

[0035] The spray assembly 2 includes a pump body arranged outside the tower body 1, and the water outlet of the pump body is connected to the spray head arranged inside the tower body 1 through a water supply pipe. The pump body delivers the coolant to the spray head through the water supply pipe, and sprays it out through the spray head, so as to achieve large-area contact between the coolant and the airflow.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
