Description

Technical Field

[0001] This utility model relates to the field of mixed bed resin regeneration technology, and in particular to an automatic mixed bed resin regeneration system. Background Technology

[0002] Condensate polishing is a key piece of equipment for ensuring high-quality steam and water, and its proper operation is one of the main factors ensuring the safe operation of the unit. The power plant's high-speed mixed bed reactor lacks a pre-filter; the high-speed mixed bed acts as both a filter and an ion exchanger. All polishing resins require periodic regeneration after a period of operation. Currently, the technology involves manual observation through a sight hole in the resin tank to determine the resin bed flow rate, resin mixing condition, and resin failure status. This leads to inaccurate assessment of resin failure, low resin utilization, inaccurate control of the acid and alkali amounts used for regeneration, and substandard effluent from the resin bed. Regeneration typically requires manual inspection of the resin in the mixed bed resin tank to check for resin failure before manual regeneration can begin, resulting in low regeneration efficiency and uncontrollable regeneration time.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] Reference Figure 1-4 An automatic regeneration system for mixed bed resin includes a first high-speed resin mixed bed 1, a second high-speed resin mixed bed 2, an iron removal filter tank 8, and a regeneration circulation pump 301.

[0025] The bottom of the iron removal filter tank 8 is provided with an inlet pipe and an outlet pipe. The inlet pipe is connected to a first supply pipe 81, and the outlet pipe is connected to a first outlet pipe. A second supply pipe 82 is connected in parallel to the first supply pipe 81 and the first outlet pipe. The first outlet pipe and the second supply pipe 82 are connected to form a third supply pipe 83.

[0026] The first high-speed resin mixing bed 1 and the second high-speed resin mixing bed 2 are provided with a first liquid inlet 101 and a second liquid inlet 102 at their top ends, and a first liquid outlet 103 and a second liquid outlet 104 at their bottom ends. The output end of the third liquid supply pipe 83 is divided into two branches and connected to the first liquid inlet 101 at the top of the first high-speed resin mixing bed 1 and the second high-speed resin mixing bed 2, respectively. The first liquid outlet 103 at the bottom of the first high-speed resin mixing bed 1 and the second high-speed resin mixing bed 2 are each connected to the inlet end of a resin trap 3 through a pipe. The outlet ends of the two resin traps 3 are connected through pipes and... The circulation pipe 30 is connected to the circulation pipe 30 and the circulation pipe 30 is connected to the third liquid supply pipe 83. The circulation pipe 30 is equipped with a regeneration circulation pump 301. The second liquid inlet 102 at the top of the first high-speed resin mixed bed 1 and the second high-speed resin mixed bed 2 are both connected to the liquid outlet main pipe 41 of the regeneration resin device through pipes. The second liquid outlet 104 at the bottom of the first high-speed resin mixed bed 1 and the second high-speed resin mixed bed 2 are both connected to the liquid inlet main pipe 51 of the regeneration resin device through pipes. The liquid outlet main pipe 41 of the regeneration resin device and the liquid inlet main pipe 51 of the regeneration resin device are both connected to the flushing pipe of the regeneration flushing pump 6.

[0027] Both the first high-speed resin mixing bed 1 and the second high-speed resin mixing bed 2 are equipped with monitoring devices. The monitoring devices include a visual sensor 11, a miniature sensor 12, and a wireless signal transceiver processing module 13. The first high-speed resin mixing bed 1 and the second high-speed resin mixing bed 2 have a visual sensor 11 on their observation windows, a wireless signal transceiver processing module 13 on their side walls, and a miniature sensor 12 on their bottom walls. The visual sensor 11 and the miniature sensor 12 are connected to the wireless signal transceiver processing module 13 via connecting cables. The wireless signal transceiver processing module 13 includes a wireless module and a signal processing module. The data collected by the visual sensor 11 and the miniature sensor 12 is processed by the signal processing module and then transmitted to the monitoring center server via the wireless module.

[0028] The two branch pipes that are divided at the output end of the third liquid supply pipe 83 are equipped with pressure gauges, pressure transmitters and flow transmitters at the first liquid inlet 101 of the first high-speed resin mixing bed 1 and the second high-speed resin mixing bed 2. Both branch pipes are equipped with manual butterfly valves and pneumatic butterfly valves.

[0029] The first liquid supply pipe 81 is equipped with a pressure gauge and a pressure transmitter, and the first liquid outlet pipe is equipped with a pressure gauge.

[0030] Raw water needs to pass through the iron removal process before entering the high-speed resin mixed bed. The bottom of the iron removal filter tank 8 is connected to the first liquid supply pipe 81 and the first liquid outlet pipe to allow the liquid to flow into the iron removal filter tank 8 for iron removal before flowing out. If the iron removal filter tank 8 is to be cleaned or repaired, the valves of the first liquid supply pipe 81 and the first liquid outlet pipe are closed, and the valve of the second liquid supply pipe 82 is opened to provide water for a short period without iron removal. After the cleaning or repair is completed, the system is switched back to the operation of the iron removal filter tank 8.

[0031] After iron removal, the liquid flows into the first high-speed resin mixed bed 1 and the second high-speed resin mixed bed 2 for fine treatment, and then is discharged. If the amount of resin is not up to standard, it flows out to the resin capture device 3 for filtration, and then enters the third liquid supply pipe 83 through the regeneration circulation pump 301 for further treatment.

[0032] The resin regeneration liquid is supplied to the first high-speed resin mixing bed 1 and the second high-speed resin mixing bed 2 through the liquid outlet manifold 41 of the regenerated resin device, and then circulated and discharged from the second liquid outlet 104 to the liquid inlet manifold 51 of the regenerated resin device, thus forming the resin regeneration process.

[0033] When the first high-speed resin mixed bed 1 and the second high-speed resin mixed bed 2 are operating, they can work synchronously. Alternatively, during maintenance, one can be shut down while the other continues uninterrupted to ensure the normal operation of the condensate polishing process. During this process, it is generally unattended, relying solely on worker inspections and observation through viewing windows and other sensors. However, abnormalities or resin failures may not be detected promptly. In such cases, the visual sensor 11 installed on the viewing window can collect real-time data on the liquid state within the high-speed mixed bed and transmit the images wirelessly to the monitoring center's display screen. The monitoring room can simultaneously monitor multiple high-speed mixed beds, transforming manual monitoring through viewing windows into a visual and intelligent monitoring system. Furthermore, a miniature sensor 12 can monitor the bottom of the high-speed mixed bed for resin failure. If either of these abnormalities is detected (after analysis by the monitoring center), personnel will be dispatched for timely handling.

[0034] Differential pressure transmitters are provided between the first inlet port 101 and the first outlet port 103 of the first high-speed resin mixed bed 1 and the second high-speed resin mixed bed 2, and a differential pressure transmitter is also provided between the first supply pipe 81 and the first outlet pipe. This facilitates timely observation of the internal pressure and inlet flow rate of the high-speed mixed bed.

[0035] The second liquid supply pipe 82 is equipped with a manual and electric valve combination 80, which includes an electric butterfly valve 801, a first manual butterfly valve 802, and a second manual butterfly valve 803. The second liquid supply pipe 82 has one electric butterfly valve 801 and one first manual butterfly valve 802 on each side of the electric butterfly valve 801. A second manual butterfly valve 803 is connected in parallel to the outer sides of the two first manual butterfly valves 802 on the second liquid supply pipe 82. Manual or electric liquid supply is achieved as needed. During manual supply, both the electric butterfly valve 801 and the first manual butterfly valve 802 are closed; during electric supply, both first manual butterfly valves 802 are open and the second manual butterfly valve 803 is closed.

[0036] A return branch pipe branches off from the outlet pipes of the two resin traps 3. These two return branch pipes are connected to the condensate main pipe 71, which is connected to the third supply pipe 83. The condensate main pipe 71 is also equipped with a manual and electric valve combination 70, which has the same structure as the manual and electric valve combination 80. If the liquid discharged from the first outlet port 103 fails to condense after passing through the resin trap 3, it is either channeled into the third supply pipe 83 using the manual and electric valve combination 70 (allowing for manual or electric control) or directly discharged into the cooling water condenser 7.

[0037] A differential pressure transmitter is installed between the inlet and outlet of the two resin traps 3. The pressure difference during the iron removal process is observed.

[0038] The housing of the wireless signal transceiver processing module 13 is equipped with an alarm sound to turn off the alarm horn. The signal processing module is equipped with a GPS positioning module, and each GPS positioning module corresponding to the signal processing module on the high-speed mixing machine has an electronic serial number. Upon arrival at the site for maintenance, the alarm can be manually turned off to prevent the sound from triggering repairs. If the worker cannot locate the faulty equipment, the location of the faulty equipment can be located via a mobile device (by entering the faulty GPS positioning module number into the device).

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
