DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0019] Example 1: As shown in the attached document Figure 1 As shown, the device for improving water quality in the chilled water system includes a filter 1. The inlet of the filter 1 is fixedly connected to a chilled water inlet pipeline 2, and the outlet of the filter 1 is fixedly connected to a chilled water outlet pipeline 3. A first backwash pipeline 4 is fixedly connected between the chilled water inlet pipeline 2 and the chilled water outlet pipeline 3. A second backwash pipeline 5 is fixedly connected to the chilled water inlet pipeline 2 between the first backwash pipeline 4 and the filter 1.

[0020] In this invention, chilled water from the chilled water inlet pipeline 2 is sent to filter 1 for filtration. The filtered chilled water is then sent to subsequent heat exchange equipment such as water coolers via chilled water outlet pipeline 3. This solves the problem of turbidity and excessive iron content in water caused by rust in existing heat exchange equipment such as water coolers. At the same time, a first backwash pipeline 4 and a second backwash pipeline 5 are added. When filter 1 is clogged and requires maintenance, chilled water is sent out through chilled water inlet pipeline 2, first backwash pipeline 4, chilled water outlet pipeline 3, chilled water inlet pipeline 2 and second backwash pipeline 5. This can quickly and effectively clean the impurities clogging filter 1, ensure the normal operation of each heat exchange device, and reduce the frequency of water replacement and operating costs.

[0021] The above-mentioned water quality improvement device for the chilled water system can be further optimized and / or improved according to actual needs:

[0022] Example 2: Its difference from Example 1 is as follows: (See attached) Figure 2 As shown, the filter 1 includes a multi-stage filter cartridge and a support platform 6. The support platform 6 is provided on the lower inner side of the filter 1. The multi-stage filter cartridge is fixed inside the filter 1 by the support platform 6. The multi-stage filter cartridge includes a cylinder 7. At least two support perforated plates 8 are provided inside the cylinder 7 from top to bottom. The support perforated plates 8 divide the inside of the cylinder 7 into a first-stage filter layer 9, a second-stage filter layer 10 and a third-stage filter layer 11 from top to bottom. A sewage discharge pipe 12 is fixedly connected to the lower part of the filter 1.

[0023] As needed, the filtration precision of the primary filter layer 9, the secondary filter layer 10, and the tertiary filter layer 11 increases sequentially, making the filtration effect of each layer better and better. During use, by setting up multi-stage filter cartridges, multi-stage filtration of chilled water can be achieved, effectively removing impurities from the chilled water, ensuring the normal operation of the water cooler equipment, and reducing the frequency of water replacement and operating costs.

[0024] Example 3: Its difference from Examples 1 to 2 is as follows: (See attached) Figure 2As shown, the first filter layer 9 and the third filter layer 11 are both quartz sand, and the second filter layer 10 is activated carbon.

[0025] In use, the three-stage filtration is adopted. After the chilled water enters the filter 1, the impurities with large particles are filtered by the upper first filter layer 9 (quartz sand filter layer), the impurities with small particles are filtered by the middle second filter layer 10 (activated carbon filter layer), and the filtered chilled water is sent to the water cooler and other heat exchange equipment after being filtered again by the lower third filter layer 11 (quartz sand filter layer).

[0026] Example 4 differs from Examples 1 to 3 in that, as shown in the accompanying Figure 1 , 2 The filter 1 further comprises a magnetic adsorption device 13, and the magnetic adsorption device 13 is a permanent magnet arranged on the outer side of the lower part of the filter 1.

[0027] In use, the rust and iron slag in the chilled water are adsorbed by the adsorption force of the magnetic adsorption device, so that the rust and iron slag do not enter the heat exchange equipment and cause internal blockage of the heat exchange equipment. When it is necessary to flush the multi-stage filter cartridge, the permanent magnet arranged on the outer side of the lower part of the filter tank can be removed, so that the rust and iron slag are discharged from the blowdown pipeline 12.

[0028] Example 5 differs from Examples 1 to 4 in that, as shown in the accompanying Figure 1 The filter 1 and the second backwashing pipeline 5 are fixedly connected to the standby chilled water inlet pipeline 15 between the inlet of the standby filter 14, and the filter 1 and the first backwashing pipeline 4 are fixedly connected to the standby chilled water outlet pipeline 16 between the outlet of the standby filter 14.

[0029] In use, the filter 1 and the standby filter 14 are used alternately, without affecting normal production.

[0030] Example 6 differs from Examples 1 to 5 in that, as shown in the accompanying Figure 1 A pressure gauge 17 is arranged on the chilled water inlet pipeline 2 between the first backwashing pipeline 4 and the second backwashing pipeline 5, and a pressure gauge 17 is arranged on the chilled water outlet pipeline 3 between the standby chilled water outlet pipeline 16 and the first backwashing pipeline 4.

[0031] In use, the blockage of the filter 1 is determined by the pressure of the pressure gauges 17, and backwashing is performed in time.

[0032] According to needs, conventional valves 18 commonly known in the art can be arranged on the pipelines of the chilled water system for improving water quality.

[0033] The above technical features constitute the embodiments of the present application, which have strong adaptability and implementation effect, and can increase or decrease unnecessary technical features according to actual needs to meet the needs of different situations.

[0034] The use process of the embodiment of the present application is as follows: normal operation process: the chilled water sent by the chilled water inlet pipeline 2 is sent to the filter 1 for filtration, and the filtered chilled water is sent to the subsequent water cooler and other heat exchange equipment through the chilled water outlet pipeline 3; backwashing process: the chilled water is sent out through the chilled water inlet pipeline 2, the first backwashing pipeline 4, the chilled water outlet pipeline 3, the chilled water inlet pipeline 2 and the second backwashing pipeline 5.
