Description

Technical Field

[0001] The utility model belongs to the technical field related to cooling tower accessory devices, and in particular relates to an overpressure alarm device for a cooling tower water tank. Background Art

[0002] A cooling tower is a heat dissipation device that uses the principle of water evaporation to dissipate waste heat generated in industry or refrigeration and air conditioning to ensure the operation of the system. It can lower the temperature of cooling water. It is a device that uses the contact between water and air to dissipate waste heat generated in industry or refrigeration and air conditioning through evaporation.

[0003] Most cooling towers are mainly composed of three parts: water removal system, water distribution system and filling system. The water distribution system is the core of the cooling tower. There are various forms of water distribution systems, such as branch-shaped water distribution, ring-shaped water distribution and water tank-type water distribution. The technologies of these water distribution methods are very mature and reliable. The water tank overpressure alarm device of the utility model is mainly used in water tank-type water distribution cooling towers. Most of the existing water tank-type water distribution systems have exhaust holes or exhaust pipes that can play the role of exhaust and pressure relief. However, the cooling tower building itself is very high. When the water pressure in the water tank is too high and the water flow overflows the exhaust pipe, the personnel on the ground cannot notice it in time. When the water pressure continues to be too high for a long time, the personnel do not take corresponding measures in time, and the stability of the entire water distribution system will be destroyed. In severe cases, the components of the water distribution system may be damaged by the water flow. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a cooling tower water tank overpressure alarm device, which adds a downpipe and a water pressure monitoring device on the basis of the original water tank, and the downpipe is connected at the H value of the exhaust pipe, and the H value represents the overpressure value of the water pressure. When the water pressure in the water tank exceeds this value, water will flow into the downpipe through the exhaust pipe, and the water pressure monitoring device can detect the water pressure in the downpipe, and convert the detected water pressure value into other forms of signal alarms to remind the operator, so that the operator can make corresponding countermeasures in time through the alarm information, and timely avoid the economic losses caused by the damage of the internal components of the cooling tower due to the continued increase of water pressure. The utility model water tank overpressure alarm device is economical and practical, and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A cooling tower water tank overpressure alarm device, the cooling tower is mainly composed of a fan, a motor, a wind tube, a water removal system, a water distribution system and a heat exchange system. The cooling tower water tank overpressure alarm device is a part of the water distribution system, including a water distribution tank, an exhaust pipe, a downpipe, a water pressure monitoring device and a pre-buried pipe. The water distribution tank is a transfer hub between the water distribution system and an external water source. The water distribution tank transports the hot water source flowing in from the outside to the inside of the cooling tower. The exhaust pipe is a device connected to the water distribution tank through a pre-buried pipe. The downpipe is connected to the exhaust pipe at the H value. The bottom of the downpipe is connected to a water pressure monitoring device. When the water pressure exceeds the H value, water will flow into the downpipe, and the water pressure monitoring device will detect the water pressure signal.

[0007] Preferably, the water distribution tank serves as a hub connecting the cooling tower and an external water source, which can reduce water pressure and store sufficient water to ensure the normal working process inside the cooling tower.

[0008] Preferably, the exhaust pipe can discharge the excess air pressure in the water distribution tank to ensure the stability of the water pressure inside the water distribution tank.

[0009] Preferably, the down pipe is connected at the height of the exhaust pipe at the H value, and when the water pressure exceeds the H value, the water will flow into the down pipe.

[0010] Preferably, the water pressure monitoring device can monitor in real time the change in water pressure when water flows into the downpipe after the water pressure in the water distribution tank exceeds the pressure. When the water pressure increases, the detected information can be converted into other signals to remind the operator, which can be recorded by the operator and take corresponding measures.

[0011] Compared with the prior art, the utility model provides a cooling tower water tank overpressure alarm device, which has the following beneficial effects:

[0012] 1. The cooling tower water tank overpressure alarm device is equipped with an exhaust pipe on the basis of the original water tank. The exhaust pipe can discharge the excess air pressure in the water tank into the air to ensure the stability of the water distribution system;

[0013] 2. The cooling tower water tank overpressure device is connected to a downpipe at the H value on the exhaust pipe. The H value represents the maximum value of the water pressure overpressure. When the water pressure exceeds the H value, water will flow from the exhaust pipe into the downpipe;

[0014] 3. The cooling tower water tank overpressure alarm device has a water pressure monitoring device installed on the downpipe. When water flows into the downpipe, the water pressure monitoring device converts the monitored water pressure into other forms of signal alarms to remind the operator so that he can quickly take corresponding measures.

[0015] This technical solution can monitor the stability of the water pressure in the cooling tower water tank in real time. The water tank overpressure alarm device consists of a water distribution tank, an exhaust pipe, a downpipe, a water pressure monitoring device and a pre-buried pipe. The water distribution tank is the core of the trough cooling tower water distribution system. Its main function is to distribute the hot water source transported by the external water inlet main pipe to the cooling tower. At this time, the stability of the water pressure inside the water tank becomes particularly important. The stability of the water pressure in the water distribution tank will directly affect the working efficiency of the entire tower. When the water pressure is too high, the internal components of the cooling tower may be washed by the water flow. The overpressure alarm device can monitor the water pressure in the water tank in real time. When the water pressure is too high, the operator can make timely adjustments to ensure the normal operation of the cooling tower. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] 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 in 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.

[0021] See also Figure 1-2 , the utility model provides a technical solution:

[0022] A cooling tower water tank overpressure alarm device, the cooling tower is mainly composed of a fan 1, a motor 2, a wind tube 3, a water removal system 4, a water distribution system 5 and a heat exchange system 6. The cooling tower water tank overpressure alarm device is a part of the water distribution system 5, including a water distribution tank 5e, an exhaust pipe 5b, a downpipe 5c, a water pressure monitoring device 5d and a pre-buried pipe 5a. The water distribution tank 5e is a transfer hub between the water distribution system 5 and an external water source. The function of the water distribution tank 5e is to transport the hot water source flowing in from the outside to the inside of the cooling tower. Because the water pressure flowing in is relatively large, the water distribution tank 5e can also play a certain role in reducing pressure. The exhaust pipe 5b is a device connected to the water distribution tank 5e through the pre-buried pipe 5a to ensure that the water pressure in the water distribution tank 5e will not be too high, and the excess pressure can be discharged into the air through the exhaust pipe 5b. The down pipe 5c is connected to the exhaust pipe 5b at the H value. When the water pressure exceeds the H value, water will flow into the down pipe 5c. At this time, the water pressure monitoring device 5d will play a role. When the water pressure exceeds the alarm value H value, the water pressure monitoring device 5d will detect the water pressure signal and convert the received information into other signals to alarm and remind the operator.

[0023] The water distribution tank 5e serves as a hub connecting the cooling tower and the external water source, which can reduce the water pressure and store sufficient water to ensure the normal working process inside the cooling tower.

[0024] The exhaust pipe 5b can discharge the excess air pressure in the water distribution tank 5e to ensure the stability of the water pressure inside the water distribution tank 5e.

[0025] The down pipe 5c is connected to the exhaust pipe 5b at the height of the H value. When the water pressure exceeds the H value, the water will flow into the down pipe 5c.

[0026] The water pressure monitoring device 5d can monitor in real time the changes in water pressure when water flows into the downpipe 5c after the water pressure in the water distribution tank 5e exceeds the pressure. When the water pressure increases, the detected information can be converted into other signals to remind the operator, which can be recorded by the operator and take corresponding measures.

[0027] Working principle and use process of the utility model: the utility model includes a water distribution tank 5e, an exhaust pipe 5b, a downpipe 5c and a water pressure detection device 5d. The utility model is suitable for a water tank type cooling tower, including a water tank overpressure alarm device. When the water pressure in the water distribution tank 5e is normal, the water tank overpressure alarm device will not send out an alarm signal; on the contrary, when the water pressure entering the cooling tower is too high, the water pressure in the water distribution tank 5e will be unstable, and the excess water pressure will overflow upward through the exhaust pipe 5b. When the water flow exceeds the H value, that is, the position where the downpipe 5c is connected to the exhaust pipe 5b, the water flow will be guided to the downpipe 5c, and flow to the water pressure monitoring device 5d through the guidance of the downpipe 5c. When the water pressure monitoring device 5d detects the water pressure, the water pressure is converted into other signals, and the alarm signal is used to remind the operator that the water pressure in the water tank is too high. The operator can quickly take corresponding measures through the alarm signal of the water pressure alarm device 5d, so as to avoid the excessive water pressure from damaging the internal components of the cooling tower.

[0028] The utility model comprises a water tank overpressure alarm device, which adds an exhaust pipe 5b, a downpipe 5c and a water pressure monitoring device 5d on the basis of a water distribution tank 5e. The exhaust pipe 5b is installed on the pre-buried pipe 5a reserved on the water distribution tank 5e by a certain fixing method. The numerical value marked on the exhaust pipe 5b in the attached figure is the H value, which is the maximum limit of the water pressure, that is, the maximum water pressure that the internal components of the cooling tower can withstand. The downpipe 5c is connected to the exhaust pipe 5b at the H value. When the water pressure exceeds the H value, the water flow will be introduced into the downpipe 5c. Under the guidance of the downpipe 5c, the water flow will be guided to the water pressure monitoring device 5d. The water pressure monitoring device 5d can convert the monitored water pressure into other signal alarms to remind the operator. The operator can quickly take corresponding measures to reduce the water pressure in the tower to avoid causing greater losses. The device can fill the gap in the current market in the water tank water distribution cooling tower in terms of water pressure overpressure alarm reminder.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
