A deep treatment route interconnected with multiple deep treatment processes is established, and according to the determined several treatment requirements, the deep treatment processes corresponding to the several treatment requirements are dynamically adjusted in sequence to form an optimized treatment route, so as to dynamically adjust the deep treatment route according to the oil quality of the phosphate ester fire-resistant oil to adapt to the treatment requirements of phosphate ester fire-resistant oils with different oil qualities, thereby reducing process redundancy.

[0020] Further, a method of identifying several degradation indicators from the initial performance parameters and evaluating the degradation indicators to determine corresponding processing requirements includes: Obtaining multiple groups of known performance parameters of phosphate ester fire-resistant oils of different oil qualities, screening out multiple basic performance indicators from all the known performance parameters, and determining standard thresholds of the multiple basic performance indicators; The initial performance parameters obtained by monitoring are compared with the standard thresholds of multiple basic performance indicators, and according to the comparison results, several basic performance indicators that are different from the standard thresholds are determined as deterioration indicators of the phosphate ester fire-resistant oil to be treated; According to the determined degradation indicators, processing requirements corresponding to the degradation indicators are evaluated.
[0021] Through the implementation of the above-mentioned phosphate fire-resistant oil online monitoring deep purification method, it is preferred to obtain the initial performance parameters of the phosphate fire-resistant oil to be treated in real time through online monitoring through integrated sensors and monitoring equipment. Multiple basic performance indicators in the initial performance parameters include but are not limited to moisture, particle contamination, volume resistivity, viscosity, etc., to provide real-time data support for the dynamic adjustment mechanism and ensure dynamic optimization of the treatment process.
[0022] As mentioned above, the standard thresholds of multiple basic performance indicators are selected based on the new oil quality standards listed in DL / T 571 "Guidelines for Operation and Maintenance of Phosphate Ester Fire-Resistant Oil for Power Plants", as shown in the performance standard indicator table in Table 1: Table 1 Performance Standard Index Table

The dynamic adjustment mechanism automatically optimizes the deep treatment route, treatment time, treatment temperature, etc. based on the data analysis results to ensure the pertinence and efficiency of the treatment process.
[0027] Furthermore, the method of dynamically adjusting the deep processing processes corresponding to a plurality of processing requirements and sequentially conducting them to form an optimized processing route includes: According to the determined processing requirements, the processing requirements are matched with the multiple deep processing processes in the deep processing route one by one; According to the matching result, several matched deep processing processes are dynamically adjusted to be turned on in sequence, and unmatched deep processing processes in the deep processing route are turned off to obtain an optimized processing route.
[0028] Furthermore, according to the matching result, the method of dynamically adjusting the matched multiple deep processing processes to be turned on in sequence includes: When any degradation index among the acid value and resistivity index, the moisture index and the particle contamination index is identified from the initial performance parameters, the degradation index is evaluated and a corresponding treatment requirement among the regeneration treatment, dehydration treatment and filtration treatment is determined, and an optimized treatment route consisting of the corresponding deep treatment process among the regeneration treatment process, the dehydration treatment process and the filtration treatment process is dynamically adjusted; When multiple degradation indicators such as acid value and resistivity, moisture and particle contamination are identified from the initial performance parameters, the degradation indicators are evaluated and the corresponding multiple processing requirements in regeneration, dehydration and filtration are determined, and an optimized processing route is dynamically adjusted, which is composed of multiple corresponding deep processing processes in the regeneration process, dehydration process and filtration process being turned on in sequence.
[0029] Furthermore, the invention also includes a method for deep purification of the phosphate fire-resistant oil to be treated by sequentially undergoing a regeneration process, a dehydration process and a filtration process: A regenerator equipped with an adsorbent is pre-set, and the phosphate ester fire-resistant oil to be treated is introduced into the regenerator at a preset pressure, and regenerated within a preset time; A vacuum tank with a vacuum environment is pre-set, the regenerated phosphate fire-resistant oil is heated to a preset temperature and introduced into the vacuum tank, and the phosphate fire-resistant oil is dehydrated within a preset time by flash steam vaporization; A mechanical two-stage filter connected in series is preset, the dehydrated phosphate fire-resistant oil is introduced into the two-stage filter at a preset pressure, and filtered within a preset time to obtain finished oil; The processing performance parameters of the finished oil are obtained through online monitoring. If the processing performance parameters do not meet the preset standards after comparison and analysis, the finished oil will be repeatedly cycled for deep processing.
[0030] Furthermore, the method of heating the regenerated phosphate fire-resistant oil to a preset temperature and introducing the regenerated phosphate fire-resistant oil into the vacuum tank, and dehydrating the phosphate fire-resistant oil by flash steam vaporization within a preset time includes: Perform vacuum treatment on the vacuum tank, and obtain the vacuum degree in the vacuum tank through online monitoring until the vacuum tank reaches a preset negative pressure value; The regenerated phosphate fire-resistant oil is heated to a preset temperature and introduced into a vacuum tank, and the phosphate fire-resistant oil introduced into the vacuum tank is atomized at the same time; The temperature data in the vacuum tank is obtained through online monitoring, and the internal temperature of the vacuum tank is raised to the preset temperature required for flash steam vaporization. The water in the phosphate fire-resistant oil is separated by flash steam vaporization, and the vaporized and separated water is led out by condensation and liquefaction.
[0031] Through the implementation of the above-mentioned phosphate fire-resistant oil online monitoring deep purification method, the deep purification treatment mainly includes three functions: regeneration treatment, dehydration treatment and filtration treatment. The regeneration treatment mainly targets the acid value and volume resistivity indicators. It uses molecular polar adsorbents and an oil pump to pressurize the phosphate fire-resistant oil. The phosphate fire-resistant oil is pressurized through a regenerator equipped with an adsorbent and fully reacts with the adsorbent in the process to complete the regeneration treatment of the phosphate fire-resistant oil, thereby reducing the acid value of the phosphate fire-resistant oil and improving the basic performance indicators such as the resistivity of the phosphate fire-resistant oil. The dehydration treatment mainly targets the moisture indicator. It uses physical vacuum flash evaporation to construct a vacuum environment and use the flash evaporation principle to remove the moisture in the phosphate fire-resistant oil. The vaporized moisture is collected in a condenser and condensed and liquefied before being removed to complete the dehydration treatment of the phosphate fire-resistant oil. Atomization treatment is used to fully vaporize the moisture in the phosphate fire-resistant oil, accelerate the vaporization speed, and ensure the degree of dehydration. The filtration treatment mainly targets the particle contamination indicator. A two-stage series mechanical impurity removal is used to connect different high-precision filters in series, so that the phosphate fire-resistant oil passes through the two-stage filter under the pressure of the oil pump. The filtration accuracy of the first-stage filter is 3 , the replacement range can be 3-10 ; The filtration accuracy of the secondary filter is 1 , the replacement range can be 1-3 The two-stage high-precision filter is connected in series to ensure that particulate impurities in the phosphate ester fire-resistant oil are fully removed. The above three processing functions can be operated separately or in conjunction, depending on the processing performance parameters of the phosphate ester fire-resistant oil obtained through online monitoring.
[0032] Furthermore, it also includes a method for pre-treating phosphate fire-resistant oil before deep purification: A backwash filter is preset, phosphate ester fire-resistant oil is introduced into the backwash filter at a preset pressure, and filtering pretreatment is performed within a preset time; A pipeline heater is preset, and in response to online monitoring that the phosphate ester fire-resistant oil filtering pretreatment reaches a preset time, the phosphate ester fire-resistant oil is introduced into the pipeline heater at a preset pressure for heating pretreatment; In response to online monitoring that the phosphate fire-resistant oil has reached a preset temperature after heating pretreatment, the phosphate fire-resistant oil is introduced into the optimized treatment route at a preset pressure for deep treatment.
[0033] Through the implementation of the above-mentioned phosphate fire-resistant oil online monitoring deep purification method, the backwash filter is used to initially and efficiently filter the large particle impurities in the phosphate fire-resistant oil, and the particle impurities accumulated in the backwash filter can be regularly removed to ensure the filtration efficiency. And the pipeline heater is used, preferably with high flow rate heating, so that the phosphate fire-resistant oil reaches the preset temperature when flowing in the pipeline, improves the treatment effect, ensures the stable heating of the phosphate fire-resistant oil, and avoids the local temperature rise of the phosphate fire-resistant oil. In addition, the heating temperature can be accurately controlled by temperature sensors and control systems to avoid overheating or underheating.
[0034] Furthermore, it also includes a method for recycling and treating phosphate ester fire-resistant oil during deep purification: A recovery tank containing a filter is preset, and the recovery tank is vacuum treated, and the vacuum degree in the recovery tank is obtained through online monitoring until the recovery tank reaches a preset negative pressure value; According to the oil circuit of the consumable device to be replaced, the phosphate fire-resistant oil in the oil circuit is introduced into the recovery tank under negative pressure and filtered; After the consumables are replaced, the filtered phosphate fire-resistant oil in the recovery tank is injected back into the oil line where the oil is drawn out at a preset pressure.
[0035] Through the implementation of the above-mentioned phosphate fire-resistant oil online monitoring deep purification method, the oil circuit of the consumable device to be replaced is used for recovery and filtration. When it is necessary to replace consumables such as the regenerator and the filter, the recovery tank is evacuated by a vacuum pump to form a negative pressure environment, and the oil circuit of the consumable device to be replaced is connected through online monitoring control, so that the phosphate fire-resistant oil flows back to the recovery tank under negative pressure. After the consumables are replaced, the phosphate fire-resistant oil in the recovery tank is 1 After the high-precision filter removes particulate impurities, the oil is pumped to the main oil circuit for further processing to achieve resource conservation and green and environmentally friendly production.
