Description

Technical Field

[0001] The utility model belongs to the technical field of resin regeneration, and in particular relates to a resin regeneration leakage monitoring device. Background Art

[0002] Condensate is an important component of boiler feed water, and condensate polishing has become an extremely important link in water vapor treatment in large power plants. Condensate polishing is to remove mechanical impurities and colloidal silica generated during the startup, operation and shutdown of the water vapor system, and to remove dissolved salts brought in from feed water, condensate and condenser leakage, so as to ensure the quality of feed water. During the operation of the polishing mixed bed, the consumption of resin exchange capacity will cause the resin to reach the end of failure, and it is necessary to carry out full and efficient regeneration to restore the resin ion exchange performance, so as to ensure the resin regeneration degree and ensure the water quality of the polishing mixed bed outlet. Therefore, one of the key points of the operation of the water vapor system of large generator sets is whether the regeneration system can operate normally and efficiently. During the backwashing and drainage process of the regeneration process, due to equipment reasons or deviations in the control process of the flushing water volume, the regenerated resin will be discharged from the tank to the resin catcher. If the operator fails to promptly discover the abnormal situation of resin leakage during the regeneration process, a large amount of resin will leak, causing economic losses. At present, there is no reliable judgment of the amount of resin leakage during the regeneration process. Once the resin leaks, it is impossible to monitor the abnormal condition of resin leakage in time. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a resin regeneration leakage monitoring device, in which a pair of pressure detection components are arranged on the wastewater flow path separated by resin filter components to perform pressure difference detection, so as to timely detect the resin leakage during the regeneration process, and the monitoring is accurate and reliable.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides a resin regeneration leakage monitoring device, comprising a resin catcher and a resin monitoring device; the resin catcher has a built-in resin filtering component, and its water inlet and water outlet are connected to the resin regeneration tower and the wastewater pool through a water inlet pipe and a water outlet pipe respectively, and the water inlet pipe, the resin filtering component, and the water outlet pipe are connected in sequence to form a wastewater flow passage; the resin monitoring device comprises a pair of pressure detection components installed on the wastewater flow passage, and the pair of pressure detection components are arranged with the resin filtering component spaced apart.

[0005] Furthermore, the resin trap has a backwash port at the bottom of the displacement side.

[0006] Furthermore, the resin filtering component comprises a filter cartridge, in which a scraper blade group is rotatably connected to the inner bottom of the filter cartridge, and the scraper blade group scrapes up the resin accumulated and attached to the inner bottom of the filter cartridge in a rotating state.

[0007] Furthermore, it comprises a rotation driving part for driving the scraping blade group to rotate, and the rotation driving part is connected to a rotating shaft of the scraping blade group connected to the filter cylinder.

[0008] Furthermore, the resin regeneration tower includes a resin separation tower, a condensate polishing treatment anion tower and a condensate polishing treatment yang tower, and the water inlet of the resin catcher is connected to the drainage outlets of the resin separation tower, the condensate polishing treatment anion tower and the condensate polishing treatment yang tower respectively through the water inlet pipeline and the pneumatic valve switching.

[0009] Furthermore, the pair of pressure detection components are respectively arranged at the water inlet and the water outlet of the resin trap, and the resin regeneration leakage is monitored by detecting the pressure difference between the water inlet and the water outlet.

[0010] Beneficial effects: The utility model utilizes the principle that there is a pressure difference between the input end and the output end in the case of blockage, and arranges a pair of pressure detection components on the wastewater flow path separated by resin filter components to perform pressure difference detection. The greater the degree of blockage during the filtration process of the resin filter component, the greater the pressure difference between the water inlet and the water outlet will be, indicating that the resin leakage is greater. The resin leakage during the regeneration process can be discovered in time, the monitoring is accurate and reliable, and an early warning can be issued in time to inform the operating personnel. According to the monitored amount of leaked resin, the regeneration process can be intervened in time, and the regeneration can be suspended when necessary to ensure that the regeneration process is safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Attached Figure 1 It is a schematic diagram of the overall structure of the utility model. DETAILED DESCRIPTION

[0012] The utility model is further described below in conjunction with the accompanying drawings.

[0013] As attached Figure 1As shown, a resin regeneration leakage monitoring device comprises a resin catcher 1 and a resin monitoring device 2; the resin catcher 1 has a built-in resin filter component 7, and its water inlet and water outlet are connected to the resin regeneration tower 4 and the wastewater pool 6 through the water inlet pipeline 3 and the water outlet pipeline 5 respectively, and the water inlet pipeline 3, the resin filter component 7, and the water outlet pipeline 5 are connected in sequence to form a wastewater flow passage; the resin monitoring device 2 comprises a pair of pressure detection components 8 installed on the wastewater flow passage, and the pair of pressure detection components 8 are arranged at intervals of the resin filter component 7. More specifically, the pair of pressure detection components 8 are respectively arranged at the water inlet and water outlet of the resin catcher 1, and the resin regeneration leakage monitoring is realized by detecting the pressure difference between the water inlet and the water outlet. The utility model utilizes the principle that there is a pressure difference between the input end and the output end in the case of blockage, and arranges a pair of pressure detection components 8 on the wastewater flow path to perform pressure difference detection at intervals of the resin filter component 7. The greater the degree of blockage during the filtration process of the resin filter component 7, the greater the pressure difference between the water inlet and the water outlet will be, indicating that the resin leakage is greater. The resin leakage during the regeneration process can be discovered in time, the monitoring is accurate and reliable, and an early warning can be issued in time to inform the operating personnel. According to the monitored amount of leaked resin, the regeneration process can be intervened in time, and the regeneration can be suspended when necessary to ensure that the regeneration process is safe and reliable.

[0014] Preferably, the pressure detection component 8 is a pressure sensor connected to a control system (PLC / DCS).

[0015] When regeneration is paused to clean the leaked resin, in order to facilitate and quickly clean it, in the utility model, the resin catcher 1 has a backwash port 9 at the bottom of the displacement side. Water is introduced through the backwash port 9 to more conveniently and quickly remove the resin accumulated and blocked on the resin filter component 7.

[0016] During the flushing process, since the resin adheres to the resin filter component 7, backwashing alone is not enough to remove it thoroughly, and a small amount of resin residue still remains. The residual resin blocks the resin filter component 7, which will affect the pressure detection and reduce the accuracy. Therefore, in the utility model, the resin filter component 7 includes a filter cartridge 10, and a scraper blade group 11 is rotatably connected to the inner bottom of the filter cartridge 10. The scraper blade group 11 scrapes up the resin accumulated and attached to the inner bottom of the filter cartridge 10 in a rotating state, and cooperates with backwashing to facilitate the removal of all the resin accumulated and blocked on the resin filter component 7. On the one hand, the thoroughness of resin removal is improved, and on the other hand, the accuracy of resin regeneration leakage detection is guaranteed.

[0017] More specifically, the utility model includes a rotary drive unit 12 for driving the scraping blade group 11 to rotate. The rotary drive unit 12 is connected to a rotating shaft 14 of the scraping blade group 11 connected to the filter cartridge 10 , and the rotary drive unit 12 uses a motor.

[0018] The resin regeneration tower 4 includes a resin separation tower 4a, a condensate polishing anion tower 4b and a condensate polishing yang tower 4c. The water inlet of the resin catcher 1 is connected to the drainage outlets of the resin separation tower 4a, the condensate polishing anion tower 4b and the condensate polishing yang tower 4c respectively through the water inlet pipeline 3 and the pneumatic valve 13.

[0019] The general process of monitoring implemented by the utility model is as follows: during the regeneration process of the resin in the resin separation tower 4a or the condensate polishing anion tower 4b or the condensate polishing yang tower 4c, the regeneration process requires the resin to be scrubbed, flushed, rinsed and other processes. When there is a deviation in the equipment reasons or the control process of the flushing water volume during the regeneration process, the regenerated resin will be discharged from the regeneration tank to the resin catcher 1 through the pipeline. The resin filter component 7 is provided in the resin catcher 1 to intercept the escaped resin. A pair of pressure detection components 8 of the resin monitoring device 2 performs pressure detection in real time and transmits the detection data to the control system (PLC\DCS). The control system analyzes the data, determines the pressure difference, promptly issues an early warning to inform the operating personnel, and determines the amount of leaked resin according to the monitored pressure difference, promptly intervenes in the regeneration process, and suspends the regeneration when necessary to ensure the safety and reliability of the regeneration process.

[0020] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
