[0030] Please refer to Figure 1 The utility model embodiment provides a cooling tower gas liquid separation equipment, including first air outlet pipe 1, second air outlet pipe 2 and gas liquid separation filter 3, wherein first air outlet pipe 1 and second air outlet pipe 2 are preferably straight cylinder, for example straight cylinder or square cylinder or straight cylinder with the bottom edge being regular polygon, and the cylinder shape of first air outlet pipe 1 and second air outlet pipe 2 needs to be the same, that is, both are cylinder or both are square cylinder, and the embodiment preferably first air outlet pipe 1 and second air outlet pipe 2 are both cylinder.

[0032] The gas flow discharged from the cooling tower enters the annular air duct 23 from the bottom of first air outlet pipe 1 and the top of first air outlet pipe 1, and the side wall of second air outlet pipe 2 corresponding to the air duct 23 area is provided with mounting port, and the gas liquid separation filter 3 is fixedly arranged in the mounting port, and the gas liquid separation filter 3 is provided with a plurality of gas liquid separation filters 3 along the circumferential side of second air outlet pipe 2. After the gas flow passes through the gas liquid separation filter 3, it is discharged to the outside, and the gas flow realizes gas liquid separation when passing through the gas liquid separation filter 3, and only needs to collect the water accumulated in the gas liquid separation filter 3, so as to realize the recovery of the volatile water of the cooling tower. When the cooling tower is not pressurized, the pressure relief port 22 is in a closed state, and when the gas pressure in the second air outlet pipe increases, the pressure relief port 22 can be opened to avoid the pressure of the cooling tower.

[0033] Please refer toFigure 2 The cooling tower gas-liquid separation device comprises a plurality of filter standard modules, each filter standard module comprises a water recovery pipe 4 and at least two gas-liquid separation filters 3 stacked in the height direction, and the water outlets of all the gas-liquid separation filters 3 in each filter standard module are connected to the water recovery pipe 4. The filter standard modules are arranged in multiple layers in the height direction of the second air outlet cylinder 2, and each layer is arranged with a plurality of filter standard modules in the circumferential direction of the second air outlet cylinder 2; the gas-liquid separation filters 3 are arranged in multiple layers in the height direction of the second air outlet cylinder 2, and each layer of gas-liquid separation filters 3 is uniformly distributed in the circumferential direction of the second air outlet cylinder 2.

[0034] Preferably, one filter standard module comprises three gas-liquid separation filters 3 stacked in the height direction; the water recovery pipe 4 in each filter standard module comprises a main pipe 41 and a plurality of branch pipes 42, the number of branch pipes 42 corresponds to the number of gas-liquid separation filters 3 in each filter standard module, each branch pipe 42 is arranged horizontally at the bottom of a gas-liquid separation filter 3 and is connected to the water outlet at the bottom of the gas-liquid separation filter 3, and the main pipe 41 vertically connects all the branch pipes 42 from top to bottom, and the main pipes 41 of all the filter standard modules are connected to an external water storage tank.

[0035] Please refer to Figure 1 and Figure 3 In this embodiment, the second air outlet cylinder 2 is composed of an external skin and an internal framework, and the part of the framework corresponding to the air duct 23 region is arranged as a mounting cage 21, the outer wall of the mounting cage 21 is not provided with a skin, the mounting cage 21 is in the form of a ring-shaped cage, and the mounting cage 21 has a plurality of mounting openings 211, each mounting opening 211 is used to mount and fix a gas-liquid separation filter 3, the windward side of the gas-liquid separation filter 3 faces the inside of the second air outlet cylinder 2, and the leeward side of the gas-liquid separation filter 3 faces the outside of the second air outlet cylinder 2.

[0036] In this embodiment, the filter standard modules are arranged in two layers in the height direction of the second air outlet cylinder 2, and each filter standard module comprises three gas-liquid separation filters 3 distributed in the height direction; correspondingly, the second air outlet cylinder 2 has two mounting cages 21 arranged one above the other, and each mounting cage 21 has three mounting openings 211 in the height direction.

[0037] Please refer to Figure 1Since the airflow in the air duct 23 will be resisted by the gas-liquid separation filter 3 when passing through the gas-liquid separation filter 3, if the air permeability efficiency of the gas-liquid separation filter 3 decreases (for example, the air permeability flow decreases due to the dirt of the filter screen), the air pressure in the second air outlet cylinder 2 will increase during the process of the cooling tower continuously discharging air into the second air outlet cylinder 2. The continuous increase of the air pressure to a certain value will cause the cooling tower to be blocked. To solve this problem, the cooling tower gas-liquid separation device of the embodiment is provided with an air pressure monitoring module and a closable pressure relief port 22 arranged at the top end of the second air outlet cylinder 2. The air pressure monitoring module includes an air pressure sensor arranged in the second air outlet cylinder 2 and located above the gas-liquid separation filter 3, a controller and an alarm device. The air pressure sensor and the alarm device are both electrically connected to the controller through a cable. The controller is pre-written with an air pressure alarm value. The air pressure sensor communicates with the controller through an electrical signal. The controller receives the electrical signal from the air pressure sensor and converts it into an air pressure value. Once the value reaches the air pressure alarm value, the controller controls the alarm device to alarm. The staff opens the pressure relief port 22 for pressure relief after receiving the alarm. A valve controlled by the controller can also be arranged on the pressure relief port 22. Once the air pressure reaches the air pressure alarm value, the controller controls the alarm device to alarm and automatically opens the valve for pressure relief.

[0038] Further, the diameter of the pressure relief port 22 is adjustable, or the opening degree of the valve arranged on the pressure relief port 22 is adjustable, so that the pressure relief speed can be controlled. While pressure relief, the airflow can also pass through the gas-liquid separation filter 3 at a normal flow rate, avoiding the decrease of the gas-liquid separation efficiency of the gas-liquid separation filter 3 caused by the opening of the pressure relief port 22 being too large and most of the airflow flowing out of the pressure relief port 22.

[0039] Further, a circular truncated cone-shaped pointed top 24 is arranged at the position higher than the first air outlet cylinder 1 of the second air outlet cylinder 2. The pressure relief port 22 is located at the top end of the pointed top 24 and directly above the top end of the first air outlet cylinder 1. The design of the circular truncated cone-shaped pointed top 24 reduces the top end of the second air outlet cylinder 2, so as to facilitate the arrangement of a smaller-diameter pressure relief port 22 and the formation of a turning position on the inner wall of the second air outlet cylinder 2 to guide the airflow and reduce the loss of flow rate when the airflow changes from upward flow to downward flow.

[0040] In summary, the cooling tower gas-liquid separation device of the embodiment has the following advantages:

[0041] The airflow discharged from the cooling tower enters from the bottom of the first air outlet cylinder 1 and is discharged from the top to the annular air duct 23. The airflow passes through the gas-liquid separation filter 3 on the cylinder wall of the second air outlet cylinder 2 and is discharged to the outside. The airflow realizes gas-liquid separation when passing through the gas-liquid separation filter 3. Only the water accumulated in the gas-liquid separation filter 3 needs to be collected to realize the recovery of the volatile water of the cooling tower.

[0042] A plurality of gas-liquid separation filters 3 are arranged along the height direction of the second air outlet cylinder 2, and a plurality of gas-liquid separation filters 3 are arranged along the circumferential direction of the second air outlet cylinder 2, so that the gas flow can pass through the gas-liquid separation filters 3 at each position of the circumferential direction of the second air outlet cylinder 2, and high-efficiency filtration is achieved.

[0043] By arranging a plurality of filter standard modules, the installation or replacement and maintenance of the gas-liquid separation filter 3 is facilitated in a module unit, and the arrangement of the water recovery pipe 4 is also facilitated in a module unit.

[0044] By arranging the pressure relief port 22, when the cooling tower is not pressurized, the pressure relief port 22 is in a closed state, and when the air pressure in the second air outlet cylinder 2 is increased, the pressurization of the cooling tower can be avoided by opening the pressure relief port 22.

[0045] By arranging the air pressure monitoring module, the pressurization of the second air outlet cylinder 2 can be prevented, and the normal exhaust of the cooling tower is avoided, so that the heat dissipation and cooling performance of the cooling tower is not affected.

[0046] The above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
