[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from equipment that needs to be cooled and discharge it into the atmosphere to ensure the normal operation of the equipment. Its principle is to use the contact between water and air to generate steam, and to take away heat through the volatilization of steam to lower the water temperature and achieve the purpose of cooling.

[0003] However, during the use of the cooling tower, the air entering the cooling tower carries impurities such as dust, which causes suspended matter such as scale and algae to form in the cooling tower. These suspended matter enters the pipe with the circulation of cooling water, reducing the thermal conductivity of the cooling water, resulting in the equipment that needs to be cooled cannot be completely cooled, and severe equipment damage may be caused.

[0004] To solve the above technical problems, the technical solution of the Chinese utility model patent announcement with patent application number CN201922293896.8 is a cooling tower, comprising a cooling tower body, an immersion type ultraviolet sterilization lamp, a filter box and a water pump, wherein a spray pipe, a filler and a water pool are sequentially arranged from top to bottom inside the cooling tower body, a plurality of sockets connected to the inside of the water pool are opened on one side of the water pool, and the immersion type ultraviolet sterilization lamp is inserted into the inside of the water pool through the sockets; the filter box and the water pump are fixed on the top of the cooling tower body, a water outlet is opened at the bottom of the filter box, and a pebble filter layer, a quartz sand filter layer and a sponge filter layer are sequentially arranged inside the filter box from top to bottom; the water inlet end of the water pump is connected to the water outlet of the filter box through a water inlet pipe, the water outlet end of the water pump is connected to a water supply pipe, and the other end of the water supply pipe passes through the top of the cooling tower body and is connected to the spray pipe.

[0005] However, the above-mentioned prior art has the following technical problems: in the above-mentioned cooling tower, impurities in the cooling water are filtered through the pebble filter layer, quartz sand filter layer and sponge filter layer in the filter box.

[0027] When backwashing the filter, it can be achieved through the following two implementations:

[0028] Implementation Method 1

[0029] In this embodiment, it is considered to detect the pressure difference before and after filtration of each filter to perform targeted backwashing. Specifically, in this embodiment, a first electronic pressure gauge is installed on the pipeline between the upper end of each filter 33 and the corresponding first outlet, and a second electronic pressure gauge is installed on the pipeline between the lower end of each filter 33 and the corresponding second inlet, so as to judge whether the filter 33 needs to be backwashed by the pressure difference between the first electronic pressure gauge and the second electronic pressure gauge.

[0030] In this embodiment, the cooling tower 10 with turbidity reduction function for the condenser is also provided with a control terminal, which is electrically connected to each electric three-way valve, each first electronic pressure gauge and each second electronic pressure gauge, and each first electronic pressure gauge and each second electronic pressure gauge are used to upload the collected pressure data to the control terminal; the control terminal determines whether the current filter needs to be backwashed according to the data uploaded by the first electronic pressure gauge and the second electronic pressure gauge corresponding to each filter; the control terminal is also used to control the switching of the electric three-way valve corresponding to the filter when the current filter needs to be backwashed, so as to backwash the filter. In this way, the control terminal obtains each pressure difference according to the pressure data received between each first electronic pressure gauge and the second electronic pressure gauge. When the pressure difference between the first electronic pressure gauge and the second electronic pressure gauge corresponding to one of the filters 33 reaches a predetermined pressure difference, the electric three-way valve corresponding to the filter 33 is controlled to close the first water outlet and open the second water outlet, and the filter 33 is backwashed. After a predetermined time, the electric three-way valve is controlled to close the second water outlet and open the first water outlet, and the backwashing operation of the filter 33 is ended, so that the filter 33 continues to perform the filtering operation.

[0031] Implementation Method 2

[0032] In this embodiment, it is considered to detect the pressure difference of the total pipeline of each filter and perform backwashing of all filters accordingly. Specifically, in this embodiment, in the second embodiment, a third electronic pressure gauge is installed on the pipeline between the first inlet and the water outlet of the cooling tower body 20, and a fourth electronic pressure gauge is installed on the pipeline between the second inlet and the water inlet of the condenser, so as to determine whether there is a filter 33 that needs to be backwashed by the pressure difference between the third electronic pressure gauge and the fourth electronic pressure gauge.

[0033] In this embodiment, the cooling tower 10 with turbidity reduction function for the condenser is also provided with a control terminal, which is electrically connected to each electric three-way valve, the third electronic pressure gauge and the fourth electronic pressure gauge. The third electronic pressure gauge and the fourth electronic pressure gauge are used to upload the collected pressure data to the control terminal; the control terminal is used to determine whether the filter needs to be backwashed according to the data uploaded by the third electronic pressure gauge and the fourth electronic pressure gauge, and control the switching of the electric three-way valves corresponding to each filter in sequence when the filter needs to be backwashed, so as to perform backwashing operations on each filter in sequence. In this way, the control terminal calculates the pressure difference according to the water pressure data detected by the third electronic pressure gauge and the fourth electronic pressure gauge received. When the pressure difference between the third electronic pressure gauge and the fourth pressure gauge reaches a predetermined pressure difference, each electric three-way valve is controlled in sequence to close the first water outlet and open the second water outlet, and each filter 33 is backwashed in sequence. After the backwashing operation is completed, each electric three-way valve is controlled in sequence to close the second water outlet and open the first water outlet, and the backwashing operation of each filter 33 is terminated, so that each filter 33 continues to perform filtering operation.

[0034] Furthermore, each filter 33 is provided with a quartz sand filter layer, and the quartz sand particle size in the quartz sand filter layer gradually increases from top to bottom to avoid continuous precipitation of tiny impurities in the gaps between the lower particles. It can also increase the contact area between the top surface of the quartz sand filter layer and the cooling water, thereby improving the treated water flow rate and filtration efficiency; and because the impurities are accumulated on the top surface of the quartz sand filter layer, the impurities can be quickly rinsed away when the filter 33 is backwashed.

[0035] The utility model uses the backwash component 34 to simultaneously perform backwash operations on each filter 33 in the filter component 30 while filtering the cooling water in the cooling tower, so as to remove impurities accumulated on the quartz sand filter layer, thereby eliminating the need to shut down the cooling tower and the condenser when cleaning the filter 33, thereby improving work efficiency.

[0036] The cooling tower 10 with turbidity reduction function for the condenser provided by the utility model can be used not only for cooling the condenser but also for other equipment requiring cooling by the cooling tower.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
