[0054] The first ion exchanger 401 and the second ion exchanger 402 are both provided with a pressure gauge for detecting the internal air pressure, and the first ion exchanger 401 and the second ion exchanger 402 are both provided with an exhaust valve.

[0055] Furthermore, the first ion exchanger 401 and the second ion exchanger 402 are both provided with a water inlet, a water outlet, a resin inlet and a resin outlet;

[0056] The resin inlet and the resin outlet are located at the sides of the first ion exchanger 401 and the second ion exchanger 402, and the resin inlet is higher than the resin outlet;

[0057] The water inlet is connected to the water pipeline 101 , the water outlet is connected to the water outlet pipeline 104 , the resin inlet is connected to the resin filling pipeline 102 , and the resin outlet is connected to the resin discharge pipeline 103 .

[0058] Preferably, when the first ion exchanger 401 is working, the system detects that the conductivity of the internal cooling water system is too high, and then closes the first ball valve 101a and the seventh ball valve 101g, and opens the second ball valve 101b and the eighth ball valve 101h. At this time, the internal cooling water flows through the second ion exchanger 402, and the system conductivity is reduced to a normal value.

[0059] Open the exhaust valve, open the fifth ball valve 101e, start the power module 200 to continuously suck the air in the resin discharge pipeline 103 and the first ion exchanger 401, and the resin in the first ion exchanger 401 is discharged along the resin discharge pipeline 103 under the action of airflow and air pressure. After the resin enters the discharge head 301, it follows the inclined baffle 301a into any resin tank to complete the emptying of the old resin.

[0060] Close the exhaust valve, open the third ball valve 101c, open the power module 200, reduce the air pressure in the first ion exchanger 401, and the new resin in any resin tank filled with new resin flows into the first ion exchanger 401 along the resin filling pipeline 102 under the action of air pressure, completing the new resin filling.

[0061] Preferably, when the first ion exchanger 401 is working, the system detects that the conductivity of the internal cooling water system is high, and then closes the first ball valve 101a and the seventh ball valve 101g, and opens the second ball valve 101b and the eighth ball valve 101h. At this time, the internal cooling water flows through the second ion exchanger 402, and the system conductivity is reduced to a normal value.

[0062] Open the exhaust valve, open the fifth ball valve 101e, start the power module 200 to continuously suck the air in the resin discharge pipeline 103 and the first ion exchanger 401, and the resin in the first ion exchanger 401 is discharged along the resin discharge pipeline 103 under the action of airflow and air pressure. After entering the discharge head 301, the resin enters the screening machine 302 along the inclined baffle 301a.

[0063] The screening machine 302 is started, and the discharged mixed resin is separated into anion resin and cation resin with different particle sizes under the action of the screening machine 302, and falls into the first resin tank and the second resin tank respectively. The anion resin and cation resin in the first resin tank and the second resin tank are regenerated respectively using a regeneration agent, and the regenerated resins are mixed and put into the third resin tank.

[0064] Close the exhaust valve, open the third ball valve 101c, open the power module 200, reduce the air pressure in the first ion exchanger 401, and the new resin in any resin tank filled with new resin flows into the first ion exchanger 401 along the resin filling pipeline 102 under the action of air pressure, completing the regenerated resin filling.

[0065] Furthermore, the resin tank module 500 includes a first resin tank, a second resin tank and a third resin tank.

[0066] The first resin tank and the second resin tank are respectively located below the first sieving machine outlet 302a and the second sieving machine outlet 302b, and are used to store the screened anionic resin and cationic resin respectively;

[0067] The third resin tank is connected to the ion exchanger module 400 via the resin filling pipeline 102 and is used to store new resin to be filled or regenerated mixed resin.

[0068] Furthermore, the first ion exchanger 401 and the second ion exchanger 402 in the ion exchanger module 400 are arranged in parallel, and are respectively connected to the inlet pipe 101 and the outlet pipe 104 through independent first ball valves 101a, second ball valves 101b, seventh ball valves 101g and eighth ball valves 101h.

[0069] It should be noted that the resin loading pipeline 102 connects the third resin tank in the resin tank module 500 to the resin inlet of the ion exchanger module 400 and is controlled by the third ball valve 101c and the fourth ball valve 101d so that new resin or regenerated resin can be automatically loaded into the ion exchanger;

[0070] This allows one ion exchanger to maintain continuous operation while the other ion exchanger is replacing the resin.

[0071] The resin discharge pipeline 103 connects the ion exchanger module 400 with the screening module 300 and the power module 200 in series to form a closed loop, so that the old resin can be discharged from the ion exchanger module 400 through the screening module 300 under the action of the airflow generated by the power module 200.

[0072] When in use, the complete use process of the valve cooling system resin automatic replacement separation system is as follows:

[0073] In the initial state, when the system starts to operate, it is assumed that the first ion exchanger 401 is in use and the second ion exchanger 402 is in standby state. At this time, the first ball valve 101a and the seventh ball valve 101g are opened, and the second ball valve 101b and the eighth ball valve 101h are closed. Cooling water enters the first ion exchanger 401 through the water supply pipe 101, and flows out from the water outlet pipe 104 after ion exchange.

[0074] Resin replacement preparation: When the system detects that the resin in the first ion exchanger 401 needs to be replaced, the second ball valve 101b and the eighth ball valve 101h are first opened to start the second ion exchanger 402. Then the first ball valve 101a and the seventh ball valve 101g are closed to stop the first ion exchanger 401 from working.

[0075] The old resin is discharged, the fifth ball valve 101e is opened, and the pump or fan in the power module 200 is started. The power module 200 is connected to the first ion exchanger 401 through the resin discharge pipeline 103, and airflow and negative pressure are generated to extract the old resin from the first ion exchanger 401.

[0076] The resin is separated, and the old resin enters the discharge head 301 of the screening module 300 through the resin discharge pipeline 103. In the discharge head 301, the resin flows along the inclined baffle 301a to the bottom opening and enters the screening machine 302 below.

[0077] Resin storage, the screener 302 separates the mixed resin into anion resin and cation resin. The separated anion resin falls into the first resin tank from the first screener outlet 302a, and the cation resin falls into the second resin tank from the second screener outlet 302b.

[0078] When new resin is loaded, the fifth ball valve 101e is closed and the third ball valve 101c is opened. The new resin or the regenerated mixed resin in the third resin tank enters the resin inlet of the first ion exchanger 401 through the resin loading pipeline 102. The power module 200 can assist the resin loading process by generating negative pressure.

[0079] After the system is restored and new resin is loaded, the third ball valve 101c and the power module 200 are closed. The first ball valve 101a and the seventh ball valve 101g are opened to put the first ion exchanger 401 back into use.

[0080] Cyclic operation, when the resin of the second ion exchanger 402 needs to be replaced, the steps from the initial state to the system recovery are repeated, except that the operation object becomes the second ion exchanger 402, and the corresponding ball valve operation also needs to be adjusted accordingly.

[0081] Resin regeneration: the anion and cation resins stored in the first resin tank and the second resin tank can be regenerated separately. The regenerated resins can be mixed and put into the third resin tank for the next resin replacement.

[0082] Continuous operation, through the above process, the system can realize automatic replacement, separation and regeneration of resin without stopping. The first ion exchanger 401 and the second ion exchanger 402 work alternately to ensure continuous operation of the system and stable water quality.

[0083] In summary, the connecting pipeline 100 connects the modules into an organic whole, the power module 200 provides the necessary power source, the screening module 300 realizes the separation of resin, the ion exchanger module 400 ensures the water quality, and the resin tank module 500 provides resin storage and supply for the entire cycle. This design realizes the automatic replacement of the valve cooling system resin and the automatic separation of the mixed resin, effectively reduces the workload of resin replacement, reduces the resin regeneration steps, and improves the utilization rate of the resin.

[0084] In summary, the present invention realizes the automatic replacement of deionized resin in the valve cooling system by designing an automatic replacement system for the resin in the valve cooling system, thereby improving the replacement efficiency and increasing the safety of the operation. The separation of anionic and cationic resins in the mixed bed resin can be realized, which greatly simplifies the steps required for the subsequent resin regeneration and increases the utilization rate of the resin. The resin can be replaced without stopping the machine, which improves the stability of the operation of the valve cooling system. The power module forms an airflow and pressure difference by sucking the air in the system to realize the automatic replacement of the resin. The old mixed resin can be separated into two single-component resins, anionic resin and cationic resin, through the action of the screening module, and then the subsequent regeneration steps are carried out. The automatic replacement of the valve cooling system resin and the automatic separation of the mixed resin are realized, which can effectively reduce the workload of resin replacement, effectively reduce the steps of resin regeneration, and improve the utilization rate of the resin.
