Description

Technical Field

[0001] This utility model relates to the technical field of humidification system supporting equipment, specifically a circulating cooling water device for a centralized humidification system. Background Technology

[0002] In existing centralized humidification systems, cooling water supply mostly adopts a single-use mode, which leads to problems such as water waste and insufficient water temperature control accuracy. In traditional devices, cooling water lacks a recycling mechanism, and the cooling power is fixed, making it impossible to adjust the cooling range according to actual needs. At the same time, water level replenishment relies on manual or single sensor control, which can easily lead to overflow or insufficient water supply, affecting the stable operation of the humidification system.

[0005] Preferably, the water level sensor is divided into an upper limit water level sensor and a lower limit water level sensor. The upper limit water level sensor senses the highest water level in the water storage tank, and the lower limit water level sensor senses the low water level in the water storage tank. The water level sensor is electrically connected to the central controller.

[0006] Preferably, a water pressure control valve is provided on the pipe between the return water pipe and the three-way valve.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0013] Please refer to 1. One embodiment of this utility model is provided: a circulating cooling water device for a centralized humidification system, including a water storage tank 1, an inlet main pipe 2 above the water storage tank 1, an electric control valve 3 on the inlet main pipe 2, the electric control valve 3 having a built-in water level sensor 4, a central controller 5 on one side of the electric control valve 3, a submersible pump 6 inside the water storage tank 1, the output end of the submersible pump 6 connected to an inlet pipe 7, a return water pipe 8 on the water storage tank 1, the return water pipe 8 connected to a three-way valve 9, one side of the three-way valve 9 and the inlet pipe 7 are both connected to a chiller 11, the three-way valve 9 is connected to a centralized humidification control cabinet 10 through a pipe, the water level sensor 4 senses the water level in the water storage tank 1 and replenishes the water in the water storage tank 1 in a timely manner, the submersible pump 6 delivers cooling water to the chiller 11, and then the cooling water returns to the water storage tank 1 through the return water pipe 8, realizing recycling.

[0014] The water level sensor 4 is divided into an upper limit water level sensor and a lower limit water level sensor. The upper limit water level sensor senses the highest water level in the water storage tank 1, and the lower limit water level sensor senses the low water level in the water storage tank 1. The water level sensor 4 is electrically connected to the central controller 5. When the upper limit water level sensor senses the water level, the electric control valve 3 closes to stop water intake; when the lower limit water level sensor senses the water level, the electric control valve 3 opens to start water intake and replenish the water storage tank 1 in a timely manner.

[0015] A water pressure control valve is installed on the pipe between the return water pipe 8 and the three-way valve 9. The circulating water enters the water storage tank 1 after the pressure is regulated, so as to realize the recycling of the circulating water.

[0016] The chiller 11 is equipped with a cooling unit, which is selected according to the power. The cooling unit is used to cool and reduce the temperature of the circulating water. The start and stop of the cooling unit is controlled by the water temperature: cooling starts when the sensed water temperature is ≥10℃ and stops when the water temperature is ≤5℃. The cooling unit can be selected according to actual needs, that is, the power is adjustable (such as 2500 watts, 5 kilowatts, etc.). By changing the power, the cooling range can be adjusted (such as cooling to 5-10℃, 0-5℃, etc.).

[0017] The centralized humidification control cabinet 10 uses an electromagnetic control system to control the three-way valve 9. The connection between the centralized humidification control cabinet 10 and the three-way valve 9 is the first path, and the connection between the water pressure control valve and the chiller 11 is the second path. When the centralized humidification control cabinet 10 sends an opening signal (e.g., when the humidity is below 40%), the first path is opened to supply water. At the same time, the second path returns to the water storage tank 1 after the pressure is regulated by the water pressure control valve, completing the circulation.

[0018] Working principle: During use, when the initial water level in the water storage tank 1 is lower than the lower limit, the lower limit water level sensor sends a signal to the central controller 5, the electric control valve 3 opens, and the main water inlet pipe 2 replenishes water to the water storage tank 1; when the water level reaches the upper limit, the upper limit sensor triggers a signal, the electric control valve 3 closes, and water replenishment stops. After the submersible pump 6 starts, it continuously pumps water from the water storage tank 1 and sends it to the cooling unit through the two-way valve; if the water temperature is ≥10℃, the cooling unit starts (using 2500 watts of power) and stops when the water temperature drops to 5℃. The cooled water enters the three-way valve through the outlet pipe: when the centralized humidification control cabinet sends an opening signal (e.g., humidity is below 40%), the first channel is opened for water supply; at the same time, the second channel returns to the water storage tank after the pressure is regulated by the water pressure control valve, completing the circulation.
