Problems solved by technology

[0004] In actual use, the value of waste heat delivered to the cooling tower varies with the actual working conditions, but the fan power of the general cooling tower is fixed; when the value of waste heat to be cooled is lower than that of the cooling tower When the power is high, it will cause a lot of waste of water resources and electricity, and cause the water quality of cooling circulating water to deteriorate due to the increase in the concentration factor. There are improvements in the existing technology

Embodiment 1

[0040] combine figure 1 and figure 2 As shown, a circulating water management device based on a cooling tower is installed based on a cooling tower 1. The cooling tower 1 includes a frame 11 and a cooling tower main body 2 installed and fixed on the frame 11. The cooling tower main body 2 is usually set It is a square structure, and a frequency conversion fan 3 is installed on the top of the main body 2 of the cooling tower. The cooling tower main body 2 is equipped with a descaling device 6 for adsorbing and removing scale. The descaling device 6 is used to adsorb and remove microorganisms, algae and scale in the cooling tower main body 2, so as to ensure the refrigeration or process equipment connected to the cooling tower 1. of normal operation. The main body 2 of the cooling tower is connected with the water inlet pipe 21 and the water outlet pipe 22. The water inlet pipe 21 and the water outlet pipe 22 are respectively connected with the external circulation pipeline 7...

Embodiment 2

[0048] combine Figure 5 and Figure 6 As shown, a cooling tower-based circulation system differs from Embodiment 1 in that a complete cooling circulation system is constructed based on multiple cooling towers 1 . A plurality of cooling towers 1 are commonly connected to the circulation pipeline 7, and the circulation pipeline 7 includes a water inlet main pipe 71 and a water return main pipe 72 that circulate and communicate with the user and the cooling tower 1, and the water outlet pipes 22 of each cooling tower 1 are connected to the water inlet The main pipe 71, and the water inlet pipe 21 of each cooling tower 1 is connected to the return water main pipe 72 to realize the pipeline circulation of circulating water, that is, the waste heat generated by the user is distributed to each cooling tower 1 by the circulating water through the return water main pipe 72 The heat exchange is completed inside, and the cooled circulating water is then distributed to each user via the...

Embodiment 3

[0050] combine Figure 7 As shown, a cooling tower-based management method differs from Embodiment 1 in that it provides a method of adjusting the actual working power of the cooling tower 1 frequency conversion fan 3 based on the amount of heat transfer of circulating water that actually flows into the cooling tower 1 . The specific adjustment steps are as follows: firstly, the water inlet temperature value T1 of the water inlet pipe 21 and the water outlet temperature value T2 of the water outlet pipe 22 are detected by the water inlet temperature detection device 4 and the water outlet temperature detection device 5 at the water inlet pipe 21 and the water outlet pipe 22. , and then calculate the actual temperature difference ΔT between the inlet water temperature value T1 and the outlet water temperature value T2, and compare the actual temperature difference ΔT with the theoretical temperature difference ΔT, and finally control the scale collector 61 and the motor of the v...

Abstract

The invention discloses a circulating water management device, a circulating system and a management method based on a cooling tower, and relates to the technical field of external hanging type cooling circulating water equipment. A water inlet temperature detection device and a water outlet temperature detection device are arranged at a water inlet pipe and a water outlet pipe of the cooling tower correspondingly, a cooling tower body is provided with a temperature and humidity detector so as to detect and obtain the actual heat exchange demand quantity, data analysis and comparison are carried out on the actual heat exchange demand quantity and the cooling tower heat exchange supply quantity, then the actual working power of a variable frequency fan of the cooling tower is properly adjusted within a reasonable range according to the comparison result, so that the actual working power of the variable frequency fan is matched with the heat exchange value of the cooling circulating water flowing into the cooling tower, then the purpose of reducing the water consumption and the electric energy loss of the cooling tower and the cooling circulating system is achieved, and then the normal operation of a refrigeration or process device is guaranteed.

Description

technical field [0001] The invention relates to the technical field of external cooling circulating water equipment, in particular to circulating water management equipment, a circulating system and a management method based on a cooling tower. Background technique [0002] The cooling tower realizes heat exchange with the external environment through circulating cooling water, so as to achieve the purpose of discharging waste heat and circulating cooling. The cooling water in the cooling tower is in direct contact with the external ambient air, and the cooling medium is cooled by latent heat (water evaporation) and sensible heat (heat exchange). [0003] The existing authorized notification number is the Chinese patent of CN207730044U, which discloses a single-phase 220V cooling tower, including a cooling tower body, a fan is fixedly arranged on the top of the cooling tower body, and a cooling device is arranged on the middle section of the cooling tower body, and the heat ...
