Technical Field

[0002] Phosphate ester fire-resistant oil is a fire-resistant hydraulic oil. With the rapid development of electric power, some large-scale thermal power plants, nuclear power plants, and large-capacity high-parameter steam turbine generator sets are also increasing. In order to meet the high-parameter requirements of the speed control systems of these units and avoid fire accidents caused by high-pressure oil leakage in the system, their speed control systems have generally adopted phosphate ester fire-resistant oil as hydraulic medium.

[0003] The main component of phosphate fire-resistant oil is triaryl phosphate. As the working medium of the hydraulic speed control system, the stability and reliability of the performance of phosphate fire-resistant oil is directly related to the operating efficiency and life of the speed control system. With the growing demand for fire-resistant oil in industries such as electricity and aviation, how to ensure that the quality of phosphate fire-resistant oil reaches the best state has become an urgent problem to be solved in the industry. Therefore, after the preparation of phosphate fire-resistant oil, it is often necessary to improve the quality of phosphate fire-resistant oil to improve the performance indicators of phosphate fire-resistant oil. However, the existing oil treatment device has a relatively single function, mostly for the blending of oil and additives, and cannot perform more functional deep treatment, so it is not suitable for the quality improvement of phosphate fire-resistant oil.

In combination with the first processing route and the second processing route set, the performance index data of the crude oil in the crude oil storage unit 1 is first obtained through online monitoring, and the degradation index of the crude oil is determined therefrom, so as to select the first processing route or the second processing route according to the processing requirements of the crude oil. That is, if it is monitored that there are phenols and other easily deteriorated components in the crude oil storage unit 1, the phosphate fire-resistant oil in the crude oil storage unit 1 is controlled to be introduced into the micro-oxidation unit 2 for treatment; if it is monitored that there are no phenols and other easily deteriorated components in the crude oil storage unit 1, the phosphate fire-resistant oil in the crude oil storage unit 1 is controlled to be introduced into the blending unit 3 for treatment.

The crude oil storage tank 11 is also connected to the micro-oxidation unit 2 and the blending unit 3 respectively through the first oil pump 12, and the crude oil temperature transmitter 13 and the crude oil level transmitter 14 are both arranged on the crude oil storage tank 11. The monitoring unit 5 includes a first detector 51 arranged on the crude oil storage tank 11, and the crude oil temperature transmitter 13, the crude oil level transmitter 14 and the first detector 51 are all electrically connected to the control cabinet 6, and are used to monitor the performance index data of the phosphate ester fire-resistant oil in the crude oil storage tank 11 online.

[0037] Through the implementation of the above-mentioned phosphate ester fire-resistant oil treatment system, the first oil pump 12 is used to inject the phosphate ester fire-resistant oil to be treated into the crude oil storage tank 11, and the control cabinet 6 receives the data of the crude oil temperature transmitter 13, the crude oil level transmitter 14 and the first detector 51, and the analysis and processing unit processes it, so as to use the crude oil temperature transmitter 13 and the crude oil level transmitter 14 to monitor the temperature and liquid level in the crude oil storage tank 11 in real time, and can accurately control and manage the temperature and injection amount of the phosphate ester fire-resistant oil in the crude oil storage tank 11, and ensure the stability of the storage environment of the phosphate ester fire-resistant oil in the crude oil storage tank 11. In addition, the performance index data of the phosphate ester fire-resistant oil in the crude oil storage tank 11 can be monitored online in real time by using the first detector 51, which enables the operator to accurately monitor the quality and performance of the crude oil. According to the real-time monitoring data, the control parameters of the crude oil storage tank 11 can also be optimized and adjusted, for example, the temperature adaptability is adjusted according to the temperature of the crude oil storage tank 11 to achieve the best storage effect. At the same time, the crude oil storage tank 11 is connected to the micro-oxidation unit 2 and the blending unit 3 respectively, so that the crude oil can be transported and processed between different units according to the real-time monitored quality and performance of the crude oil, that is, the first processing route or the second processing route is selected to optimize the process route to the greatest extent, improve the processing efficiency of phosphate fire-resistant oil, and ensure the processing effect and product quality.

[0038] Further, the micro-oxidation unit 2 includes an oxidation kettle 21, an oxygen storage tank 22, a second oil pump 23, an oxidation temperature transmitter 24, an oxidation level transmitter 25, and an oxidation pressure transmitter 26. The oxidation kettle 21 is connected to the crude oil storage unit 1 and the oxygen storage tank 22 respectively, and a catalytic component is provided in the oxidation kettle 21, which is used to introduce the phosphate fire-resistant oil in the oxidation kettle 21 through the catalytic component and oxygen for micro-oxidation reaction. The oxidation kettle 21 is connected to the blending unit 3 through the second oil pump 23, and the oxidation temperature transmitter 24, the oxidation level transmitter 25, and the oxidation pressure transmitter 26 are all arranged on the oxidation kettle 21. The monitoring unit 5 also includes a second detector 52 arranged on the oxidation kettle 21.

[0039] Through the implementation of the above-mentioned phosphate fire-resistant oil treatment system, the catalytic component arranged in the oxidation kettle 21 is used to promote the micro-oxidation reaction of the phosphate fire-resistant oil and oxygen, so as to efficiently remove the easily deteriorated components such as phenols in the phosphate fire-resistant oil, and improve the micro-oxidation treatment efficiency of the phosphate fire-resistant oil. The control cabinet 6 receives and processes the data of the oxidation temperature transmitter 24, the oxidation liquid level transmitter 25, the oxidation pressure transmitter 26 and the second detector 52, so that the oxidation temperature transmitter 24, the oxidation liquid level transmitter 25 and the oxidation pressure transmitter 26 can monitor and control the reaction conditions such as the temperature, liquid level and pressure in the oxidation kettle 21 in real time, and ensure that the micro-oxidation treatment is carried out under appropriate conditions. The operator can monitor the quality and performance of the phosphate fire-resistant oil in the micro-oxidation treatment process in real time, so as to ensure the efficiency of the micro-oxidation treatment and the quality of the phosphate fire-resistant oil after treatment. The control parameters of the micro-oxidation treatment can also be optimized and adjusted according to the real-time monitoring data, for example, the oxygen input amount is adjusted according to the oxygen concentration in the oxidation kettle to achieve the best reaction effect.

[0040] Furthermore, the catalytic assembly includes a catalyst packing layer 211 and an atomizing nozzle 212 arranged in the oxidation kettle 21. The catalyst packing layer 211 divides the internal space of the oxidation kettle 21 into an atomizing chamber and an oil chamber from top to bottom. The crude oil storage unit 1 is connected to the oil chamber, and an oxygen control valve is provided on the pipeline connecting the oxygen storage tank 22 and the oxidation kettle 21.

Among them, a plurality of reaction pores are formed on the catalyst packing layer 211.

[0041] Through the implementation of the above-mentioned phosphate fire-resistant oil treatment system, the catalyst packing layer 211 is preferably filled with copper material as a catalyst, and the multiple reaction pores formed on the catalyst packing layer 211 can increase the contact area between the phosphate fire-resistant oil and oxygen, so as to promote the micro-oxidation treatment and improve the efficiency of the micro-oxidation treatment. At the same time, the phosphate fire-resistant oil is atomized by the atomizing nozzle 212, so that it is more fully mixed with oxygen, thereby improving the uniformity and conversion rate of the micro-oxidation treatment. In addition, by controlling the oxygen control valve, the oxygen flow entering the oxidation kettle 21 can be accurately adjusted, so as to better control the conditions of the micro-oxidation treatment, so that after the phosphate fire-resistant oil is subjected to the micro-oxidation treatment, only the phenols and other easily deteriorated components in the phosphate fire-resistant oil are removed, and the phosphate fire-resistant oil is prevented from being over-oxidized, so as to ensure that the performance of the phosphate fire-resistant oil is improved, thereby extending the service life of the phosphate fire-resistant oil.

[0042] Furthermore, the blending unit 3 includes a blending kettle 31, an additive proportioning component, a first stirring component, a blending temperature transmitter 32 and a blending liquid level transmitter 33. The blending kettle 31 is connected to the crude oil storage unit 1, the micro-oxidation unit 2 and the additive proportioning component respectively. The first stirring component is arranged in the blending kettle 31, and is used to introduce the phosphate anti-oil in the blending kettle 31 to undergo a blending reaction through the first stirring component and the additive. The blending temperature transmitter 32 and the blending liquid level transmitter 33 are both arranged on the blending kettle 31. The monitoring unit 5 also includes a third detector 53 arranged on the blending kettle 31, and the blending temperature transmitter 32, the blending liquid level transmitter 33 and the third detector 53 are all electrically connected to the control cabinet 6, and are used to monitor the performance index data of the phosphate anti-oil in the blending kettle 31 online.

[0043] Through the implementation of the above-mentioned phosphate fire-resistant oil treatment system, the additive ratio component is used to accurately control the addition ratio of various additives, ensuring that the blended phosphate fire-resistant oil has stable performance. The first stirring component fully mixes the phosphate fire-resistant oil with the additive to improve the blending uniformity, thereby improving the performance of the fire-resistant oil.

The stirring directions of two adjacent stirring blades 39 are opposite.

[0047] Through the implementation of the above-mentioned phosphate fire-resistant oil treatment system, multiple stirring blades 39 are arranged on the stirring rod 38, and the stirring directions of two adjacent stirring blades 39 are opposite. When the variable frequency motor 37 drives the stirring rod 38 to rotate, the multiple stirring blades 39 can rotate with it and generate convection stirring to form a stronger stirring effect, so that the materials are mixed more evenly, and the additives or other materials are effectively prevented from settling at the bottom of the container. Among them, the variable frequency motor 37 can adjust the stirring speed as needed, adapt to different blending processes and material characteristics, improve the stirring efficiency, shorten the blending time, and reduce the bubbles generated during the stirring process to avoid the negative effects caused by bubbles, such as reducing the influence of bubbles on the blending performance of phosphate fire-resistant oil.

[0048] Further, the finished oil storage unit 7 includes a finished oil storage tank 71, a nitrogen storage tank 72, a fourth oil pump 73, a finished oil temperature transmitter 74, a tank pressure transmitter 75, and a finished oil level transmitter 76.

[0049] Through the implementation of the above-mentioned phosphate fire-resistant oil treatment system, the finished oil obtained after the blending treatment of the phosphate fire-resistant oil is introduced into the finished oil storage tank 71, and nitrogen is filled into the finished oil storage tank 71 using the nitrogen storage tank 72. Since nitrogen is an inert gas, the air in the finished oil storage tank 71 can be removed by filling nitrogen, and the gas content in the phosphate fire-resistant oil in the finished oil storage tank 71 can be reduced, which can effectively prevent the phosphate fire-resistant oil from contacting with oxygen in the air, thereby avoiding oxidation and deterioration of the phosphate fire-resistant oil and extending its service life. And based on the drying performance of nitrogen, moisture and impurities can be prevented from entering the finished oil storage tank 71, further protecting the quality of the phosphate fire-resistant oil. The control cabinet 6 receives and processes the data of the finished oil temperature transmitter 74, the tank pressure transmitter 75, the finished oil level transmitter 76 and the fourth detector 54, so that the finished oil temperature transmitter 74, the tank pressure transmitter 75 and the finished oil level transmitter 76 can monitor the temperature, level and pressure in the finished oil storage tank 71 in real time, which is convenient for accurate control and ensures the stability of the nitrogen filling process. The operator can monitor the quality and performance of the phosphate ester fire-resistant oil in the finished oil storage tank 71 in real time, and can optimize and adjust the control parameters of the finished oil storage tank 71 according to the real-time monitoring data, such as controlling the pressure of nitrogen filling to reduce the unstable pressure in the finished oil storage tank 71, thereby ensuring the storage effect of the phosphate ester fire-resistant oil in the finished oil storage tank 71 to meet the use requirements of the phosphate ester fire-resistant oil.

[0050] Further, the deep purification unit 4 includes a regeneration dehydrator 41 and a finished oil dehydrator 42.

[0051] Through the implementation of the above-mentioned phosphate fire-resistant oil treatment system, the phosphate fire-resistant oil can be regenerated and dehydrated by using the regeneration dehydrator 41. When the phosphate fire-resistant oil after micro-oxidation treatment enters the blending kettle, the additive proportioning component and the first stirring component and other components are not running, so that the phosphate fire-resistant oil in the blending kettle first enters the regeneration dehydrator 41 through the processing loop 8 for regeneration and dehydration. If it is determined through online monitoring that the performance index data of the phosphate fire-resistant oil meets the threshold value of the preset index, the phosphate fire-resistant oil after regeneration and dehydration is directly introduced into the finished oil storage tank 71 for storage. And when it is needed, the phosphate fire-resistant oil in the finished oil storage tank 71 is deeply dehydrated by the finished oil dehydrator 42 and then transported to the equipment that needs to be used.
