Description

Technical Field

[0001] This utility model relates to a water treatment system, specifically a pre-filtration device for a water treatment system. Background Technology

[0002] The ACS6000 water treatment system is an 11MW medium-voltage variable frequency drive that uses a water-cooled cooling system. Due to the requirements for insulation and anti-scaling of cooling pipes, the cooling water needs to be purified. The ACS6000 water treatment system also needs to be replenished with water periodically. The replenished purified water needs to be further purified using a deionizer. During this time, the ACS6000 water treatment system cannot be used and needs to be shut down for 2-3 hours, which reduces the working efficiency of the water treatment system. Because the deionizer is frequently used with purified cooling water and purified water, the service life of the deionizer is reduced to only 1 year. Utility Model Content

[0003] The technical problem to be solved by this utility model is how to reduce downtime and extend the service life of deionizers.

[0004] This utility model solves the above-mentioned technical problems through the following technical means:

[0005] This utility model provides a pre-filtration device for a water treatment system, including a first container and a second container capable of holding water. The first container is connected to a deionization tank via a water pipe, and a first valve and a water pump are installed in the water pipe. The second container is connected to the deionization tank via a water pipe, and a second valve is installed in the water pipe. The deionization tank is then connected to the second container via a water pipe.

[0006] Beneficial effects: This utility model can purify pure water in advance through a pre-filter device in the water treatment system, eliminating the need for further purification by the ACS6000 water treatment system, thus improving the working efficiency of the ACS6000 water treatment system and further extending the service life of the deion tank.

[0007] Preferably, the first container is provided with a first liquid level sensor and a first conductivity transmitter.

[0008] Beneficial effects: This utility model uses a first liquid level sensor and a first conductivity transmitter to detect the water level and conductivity value in a first container.

[0009] Preferably, the second container is equipped with a second liquid level sensor and a second conductivity transmitter.

[0010] Beneficial effects: This utility model uses a second liquid level sensor and a second conductivity transmitter to detect the water level and conductivity values ​​in a second container.

[0011] Preferably, both the first valve and the second valve are solenoid valves.

[0012] Preferably, the water pump is an electric diaphragm pump.

[0013] Preferably, a programmable controller is also provided to control the opening and closing of the first valve, the second valve, and the water pump.

[0014] Preferably, the programmable controller is configured with water level and conductivity values. The first liquid level sensor, the first conductivity transmitter, the second liquid level sensor, and the second conductivity transmitter are all connected to the programmable controller. The detected water level and conductivity values ​​are compared with the water level and conductivity values ​​configured by the programmable controller to control the opening and closing of the first valve, the second valve, and the water pump.

[0015] Preferably, the water level is 500 mm or 400 mm; the electrical conductivity is 0.5 μS / m or 0.3 μS / m.

[0016] Preferably, the programmable controller is equipped with an audible and visual alarm.

[0017] Preferably, the audible and visual alarm is an alarm indicator light and a driving buzzer.

[0018] Beneficial effect: When the conductivity value of the water in the second container is greater than 0.3 μS / m, the alarm indicator light and the driving buzzer will remind the operator to pay attention. Only when the conductivity value of the water in the second container is not greater than 0.3 μS / m can it be used in the water cooling system of the ACS6000 water treatment system.

[0019] This invention sets up a first container and a second container. The conductivity values ​​of the water in the first container and the second container are detected by a first conductivity transmitter and a second conductivity transmitter, respectively. By comparing the conductivity values ​​in the first container and the second container, it is possible to indirectly determine whether the purification function of the deion tank is effective. If it is ineffective, the deion tank can be replaced in time, thereby improving the working efficiency of the pre-filtration device of the water treatment system. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] according to Figure 1-2 As shown, this embodiment provides a pre-filtration device for a water treatment system, including a first container 10 and a second container 20 capable of holding water. The first container 10 is connected to a deionization tank 30 via a water pipe 50, and a first valve 51 and a water pump 40 are installed in the water pipe 50. The second container 20 is connected to the deionization tank 30 via a water pipe 50, and a second valve 52 is installed in the water pipe 50. The deionization tank 30 is then connected to the second container 20 via a water pipe 50.

[0025] like Figure 1 As shown, the first container 10 and the second container 20 share a section of water pipe 50. A water pump 40 is installed in the shared water pipe 50. The water pump 40 is an electric diaphragm pump. The electric diaphragm pump can pump the water in the first container 10 to the deion tank 30 for purification. The electric diaphragm pump can also pump the water in the second container 20 to the deion tank 30 for purification. Finally, the purified water flows into the second container 20 through the water pipe 50.

[0026] The first container 10 is equipped with a first level sensor 11 and a first conductivity transmitter 12. Similarly, the second container 20 is equipped with a second level sensor 21 and a second conductivity transmitter 22. The first level sensor 11 and the second level sensor 21 are used to detect the volume of water in the first container 10 or the second container 20 and whether it has reached the required water level value. The first conductivity transmitter 12 and the second conductivity transmitter 22 are used to detect the conductivity value of the water in the first container 10 or the second container 20.

[0027] The pre-filtration device of the water treatment system is also equipped with a programmable controller (PCC). The PCC controls the first valve 51, the second valve 52, and the water pump 40 via a PLC. The first liquid level sensor 11, the first conductivity transmitter 12, the second liquid level sensor 21, and the second conductivity transmitter 22 are all connected to the PCC. The PCC sets the water level and conductivity values ​​for the first container 10, with a water level of 500 mm and a conductivity value of 0.5 μS / m. When the water level in the first container 10 reaches 500 mm and the conductivity value is greater than 0.5 μS / m, the PCC opens the first valve 51 via the PLC and starts the water pump 40, allowing the water in the first container 10 to flow into the deion tank 30 for purification. The purified water then flows into the second container 20 through the water pipe 50. Similarly, the PCC sets the water level and conductivity values ​​for the second container 20. The water level in the second container 20 is 400mm, and the conductivity is 0.3μS / m. When the water level in the second container 20 is greater than 400mm, the programmable controller shuts off the water pump 40 via the PLC. Then, the second conductivity transmitter 22 detects the conductivity of the water in the second container 20. If it is greater than 0.3μS / m, the programmable controller opens the large valve 52 via the PLC and starts the water pump 40, allowing the water in the second container 20 to be passed into the deion tank 30 for further purification. The purified water then flows into the second container 20 through the water pipe 50, and the second conductivity transmitter 22 detects the conductivity of the water in the second container 20 again. The purification cycle continues until the conductivity of the water in the second container 20 is less than or equal to 0.3μS / m, at which point the purification cycle ends. The water purification process of the pre-filtration device in the entire water treatment system is completed, and the water can be directly used in the water cooling system of the ACS6000 water treatment system.

[0028] The programmable controller is equipped with an audible and visual alarm, which consists of an alarm indicator light and a driving buzzer. It is used to remind operators that when the conductivity of the water in the second container is greater than 0.3 μS / m, the audible and visual alarm will be triggered, the alarm indicator light will flash, and the driving buzzer will emit an alarm sound to alert operators. The conductivity of the water in the second container must not be greater than 0.3 μS / m in order to be used in the water cooling system of the ACS6000 water treatment system.

[0029] The working principle of the pre-filter device in the water treatment system of this embodiment is as follows:

[0030] like Figure 2 As shown, firstly, the pre-filter and programmable controller of the water treatment system are turned on, and purified water is added to the first container 10. The first liquid level sensor 11 detects whether the water level in the first container 10 has reached 500 mm. If it has not reached 500 mm, purified water is added. If it has reached 500 mm, the first conductivity transmitter 12 detects the conductivity of the purified water in the first container 10. If it is greater than 0.5 μS / m, the programmable controller opens the first valve 51 and starts the electric diaphragm pump through the PLC to pump the purified water in the first container 10 to the deion tank 30 for purification. The purified water flows into the second container 20 through the water pipe 50. When the second liquid level sensor 21 detects that the water level in the second container 20 is greater than 400 mm, the programmable controller closes the first valve 51 and the electric diaphragm pump through the PLC.

[0031] Secondly, the conductivity value of the purified water in the second container 20 is detected by the second conductivity transmitter 22. If the conductivity value is greater than 0.3 μS / m, the programmable controller's audible and visual alarm will be triggered, the alarm indicator light will flash, and the buzzer will sound an alarm to alert the operator. At the same time, the programmable controller opens the second valve 52 and starts the electric diaphragm pump through the PLC to pump the purified water in the second container 20 to the deion tank 30 for further purification. The purified water flows into the second container 20 through the water pipe 50, and then the conductivity value of the purified water in the second container 20 is detected by the second conductivity transmitter 22 again. This process continues until the conductivity value of the purified water in the second container 20 is less than or equal to 0.3 μS / m. At this point, the purified water in the second container 20 meets the water requirements of the ACS6000 water treatment system's water cooling system, and the water purification work of the pre-filtration device of the entire water treatment system is completed.

[0032] This embodiment uses a pre-filter device in the water treatment system to purify the pure water in advance. The purified water can be directly used in the ACS6000 water treatment system, so the ACS6000 water treatment system does not need to further purify the pure water, which improves the working efficiency of the ACS6000 water treatment system and thus further extends the service life of the deion tank.

[0033] In this embodiment, a first container 10 and a second container 20 are set up. The conductivity values ​​of the water in the first container 10 and the second container 20 are detected by the first conductivity transmitter 11 and the second conductivity transmitter 22, respectively. By comparing the conductivity values ​​in the first container 10 and the second container 20, it is possible to indirectly determine whether the purification function of the deion tank 30 is effective. If it is ineffective, the deion tank 30 can be replaced in time to improve the working efficiency of the pre-filtration device of the water treatment system.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
