I. Principle of system measurement and control        

1, YL-90F Online automatic monitoring of effluent hardness

The equipment operates unattended. Faults automatically alarm and upload. Any operation status and control can be displayed and completed in the control room through the system,This system is equipped with reserved ports for connection with the heat network automatic control system, allowing information such as the system's operating status, inlet and outlet water quality, and water tank liquid level to be uploaded to the heat network central control room.

"Realize"24The water hardness of the softened water equipment is automatically monitored online every hour15The hardness of the effluent water is tested once every minute (the test time can be adjusted), the failure points of the resin work are identified, and the resin regeneration program is started immediately, neither ahead of nor behind schedule. This ensures that the working exchange capacity of the resin is maximized while keeping the hardness index at the outlet of the water softening equipment within the calibrated range. Compared with the same model of water softener, it can save energy annually20%-30%Operating costs can be reduced, thereby truly achieving the goal of preventing boiler scaling, maintaining boiler efficiency, and energy conservation and emission reduction.

The hardness monitoring system applies the principle of colorimetric analysis to automatically sample the effluent from the softened water system once at the set time. Each time a certain amount of hardness reaction reagent is automatically injected into the quantitatively sampled water, different hardness sampled water will present different wavelengths. Relying on the principle of photoelectric conversion, the hardness detection is completed. The principle is simple, the technology is reliable and the sensitivity is high.

After using this equipment, since it measures hardness by time, regeneration is only carried out when the water quality is substandard. Therefore, the equipment can be extended20%-30%The water output and the consumption of regenerated salt can be reduced by approximately5120Kilogram7680Kilogram The consumption of reclaimed water can be reduced300Tons of450Tons.

2,YL-90FPrinciple of hardness monitoring

The hardness monitoring system applies the principle of colorimetric analysis to automatically sample the effluent from the softened water system once at the set time. Each time a certain amount of hardness reaction reagent is automatically injected into the quantitatively sampled water, different hardness sampled water will present different wavelengths. Relying on the principle of photoelectric conversion, the hardness detection is completed. The principle is simple, the technology is reliable and the sensitivity is high.

The monitoring system automatically samples and also uses titration, consuming a trace amount of the solution each time. Search for the critical value of water hardness during regeneration. Other data are irrelevant to the control of regeneration instructions. The hardness index of the regeneration instruction soft water is0.03mmol/L.

The benchmark value for system comparison is0.03mmol/L. Greater than0.03mmol/LThis indicates that the water quality is substandard, less than0.03mmol/LThis is qualified water quality.

Fully automatic water softening equipment is usually unattended. Therefore, to test whether the water softening equipment is effective and whether the water quality meets the national standards and the anti-scaling requirements, an automatic continuous analysis and detection of the hardness of the water output from the water softening equipment is adopted. Based on the hardness of the water output from the water softening equipment, the regeneration program is controlled and initiated.

Ii. Equipment Features

Control system configuration

2.1 The entire process adopts the United States.ARMThe company is controlled by a microcomputer core chip and features a touch screen operation interface (  4.3" 7The inch can be optionally equipped with German Siemens It can display the operating status, including the working status of each valve during system operation, the direction of water flow, the hardness value of the inlet water, the hardness value of the outlet water, and the hardness value of the secondary return water, which are displayed in real time and accurately.

2.2 The regeneration status display shows the working status of each valve at each step of the system regeneration, the direction of water flow, and all on-site operations can be synchronously operated in the main control, achieving seamless connection with the Fulaike water softener, which is reliable.

2.3 The water hardness index shows that the hardness index of the effluent water quality is displayed in real time during the system operation. When the effluent water quality does not meet the standard, regeneration is automatically started. After regeneration is completed, a re-inspection is conducted for confirmation.

2.4 Hardness detection, water quality hardness index display, automatic dosing, automatic flushing, automatic filling, automatic mixing, automatic detection. When the system is in operation, the hardness index of the effluent water quality is displayed in real time, and a dosing shortage alarm is triggered and uploaded. One supply of medicine is sufficient3-6With a usage cycle of one month, all historical data within a heating quarter can be queried and exported.

2.5 The alarm display shows fault alarms in real time, such as detector faults, regeneration operation faults, secondary backwashing faults, etc. It has the function of detecting water leakage in the computer room. When water leakage is detected in the computer room, the power supply will be automatically cut off and the data will be uploaded to the main control,At the same time, start the sewage pump in the computer room to work and reduce equipment loss.

2.6 It has an extension function and can be achieved by upgrading the probe module without adding the main equipmentPH,Real-time monitoring and upload of conductance, residual chlorine, etc.

2.7 The device's operating system supports the function of upgrading the operating system with a USB flash drive.

2.8 Alarm display: It can show fault alarms in real time, such as detector faults, regeneration operation faults, secondary backwashing faults, etc., and historical alarm records can be queried and exported.
