Description

Technical Field

[0001] The invention belongs to the technical field of phosphate fire-resistant oil for electric power, and in particular relates to a method for rapidly evaluating the stability performance of fire-resistant oil. Background Art

[0002] Phosphate ester fire-resistant oil is used in the turbine speed control system of power plants. It has lubricating and flame retardant effects. Its quality determines the safety and reliability of the speed control system, and also affects the service life of the oil itself. The better the stability of phosphate ester fire-resistant oil, the slower the oil deterioration rate during use, and the higher the safety and reliability of equipment operation. If the deterioration rate is fast, the acid value increases rapidly and the resistivity decreases gradually, which will cause corrosion to the equipment and seriously threaten the safe and stable operation of the equipment. Therefore, it is very important to evaluate the performance of phosphate ester fire-resistant oil.

[0003] At present, the evaluation of the performance of phosphate ester fire-resistant oil is mainly based on the technical index system in DL / T571 "Guidelines for Operation and Maintenance of Phosphate Ester Fire-Resistant Oil for Power Plants" widely used in the power industry. This standard specifies a number of key parameters including acid value, resistivity and moisture content, providing a clear basis for evaluation for power generation companies. When all indicators of phosphate ester fire-resistant oil meet the standard requirements, it is considered a qualified product and can be safely put into use; otherwise, remedial measures such as oil regeneration and replacement of new oil should be taken according to the specific situation to restore or improve the performance of the oil.

[0004] However, although this method has been widely adopted in practice and has played an important guiding role, its limitations cannot be ignored. The testing process of some key indicators such as hydrolysis stability and oxidation stability is complicated and time-consuming, which not only increases the testing cost, but also may delay the timely treatment of oil products due to the long testing cycle, posing a potential threat to the safe operation of the power generation system.

[0005] In view of the above shortcomings, the power industry is also constantly exploring more efficient and accurate methods for evaluating the performance of phosphate fire-resistant oils. The closed cup aging test method for power oil is one of them. It accelerates the aging process of oil products under specific conditions to simulate the deterioration in long-term operation, thereby evaluating its stability. However, this method also faces the problem of long test cycles (such as 164 hours), which limits its flexibility and efficiency in practical applications. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that the stability of phosphate ester fire-resistant oil cannot be quickly evaluated in the above-mentioned prior art, and to provide a method for quickly and accurately evaluating the flame retardant performance of phosphate ester, which has the characteristics of short detection cycle and high accuracy.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] S2: Mix a metal catalyst, water and triaryl phosphate and add them into a microwave reactor for microwave catalysis and continuously introduce oxygen. After the microwave catalytic reaction is completed, the oil sample is taken out after cooling, and the metal catalyst is filtered out to obtain a treated oil sample. The acid value and resistivity of the oil sample are tested to evaluate its stability.

[0011] Preferably, the metal salt is one or more of copper sulfate, manganese sulfate and cobalt sulfate.

[0016] Preferably, the flow rate of the oxygen introduced is 100 to 500 mL / min.

[0017] Preferably, the purity of the oxygen is not less than 99.9%.

[0018] Preferably, the power of the microwave reactor is 100-1000W.

[0019] Preferably, the microwave catalysis time is 30 to 60 minutes.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The metal salt of the present invention is loaded on a carrier to form a metal catalyst with a porous structure, and the metal catalyst can promote the generation of free radicals. At the same time, the present invention adopts microwave catalysis, and under the action of oxygen, the system can generate a large number of free radicals in a short time, accelerating the hydrolysis and oxidation process of unstable triaryl phosphate in phosphate fire-resistant oil, so as to achieve the purpose of quickly evaluating its performance in a short time. DETAILED DESCRIPTION

[0024] It should also be understood that the terms used in the present specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0025] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0026] The present invention proposes a method for rapidly evaluating the performance of phosphate fire-resistant oil by using microwave catalysis. The main component of phosphate fire-resistant oil is triaryl phosphate, and its degradation usually includes two processes of hydrolysis and oxidation. Hydrolysis refers to the cleavage of ester bonds in triaryl phosphate to generate monobasic or dibasic acids and free phenols, resulting in an increase in the acid value of the oil sample; oxidation refers to the free radical chain reaction of hydrocarbon substituent groups in triaryl phosphate, resulting in the degradation of phosphate. The present invention adopts microwave catalysis, and under the action of oxygen, the system can generate a large number of free radicals in a short time, accelerate the hydrolysis and oxidation process of unstable triaryl phosphate in phosphate fire-resistant oil, so as to achieve the purpose of rapidly evaluating its performance in a short time.

[0027] The present invention provides a method for quickly evaluating the performance of phosphate fire-resistant oil based on microwave catalysis, which specifically comprises the following steps:

[0028] S1: dissolving a metal salt in water, mixing and stirring to fully dissolve; then adding a carrier, mixing fully, and then evaporating and drying to remove water to obtain a metal catalyst with a porous structure;

[0029] S2: Mix a metal catalyst, water and a triaryl phosphate and add them into a reaction vessel, place the reaction vessel in a microwave reactor, turn on the microwave reactor and the stirring device, continuously introduce oxygen, and after microwave catalysis for a period of time at a certain power, close the reactor, take out the oil sample after cooling, filter out the metal catalyst, obtain the treated oil sample, detect the acid value and resistivity of the oil sample, and evaluate its stability.

[0030] The metal salt is one or more of copper sulfate, manganese sulfate and cobalt sulfate. The metal salts such as copper sulfate, manganese sulfate and cobalt sulfate are selected. These metal ions have good catalytic activity and cooperate with microwaves to promote the oxidation reaction of phosphate fire-resistant oil, thereby simulating the degradation process in actual operation; the carrier is one or more of diatomaceous earth, kaolin and molecular sieve. Using diatomaceous earth, kaolin and molecular sieve as carriers not only increases the specific surface area of ​​the catalyst, improves the dispersibility and stability of the catalyst, but also enhances the contact efficiency between the catalyst and the reactant, and accelerates the reaction rate; the mass ratio of the metal salt to the carrier is (1-10): (1-20).

[0031] The mass of the metal catalyst in S2 is 2% to 5% of the mass of the triaryl phosphate; the mass of the water in S2 is 1% to 3% of the mass of the triaryl phosphate.

[0032] The flow rate of the oxygen introduced is 100-500 mL / min; the purity of the oxygen is not less than 99.9%; the continuous introduction of high-purity (not less than 99.9%) oxygen simulates the working environment of phosphate fire-resistant oil under high temperature, high pressure and oxygen presence, accelerates the oxidative degradation process, and makes the evaluation closer to the actual working conditions.

[0033] The power of the microwave reactor is 100-1000W; the microwave catalysis time is 30-60min.

[0034] The microwave reactor is a variable frequency microwave reactor. The present invention adopts a variable frequency microwave reactor, which can achieve the high temperature and high pressure conditions required for the reaction in a relatively short time, while avoiding the temperature gradient problem in the traditional heating method, and ensuring the uniformity and controllability of the reaction; the water is deionized water.

[0035] The present invention utilizes the high efficiency of microwave catalysis, greatly shortens the evaluation cycle, and improves work efficiency.

[0064] First, the water content of the phosphate fire-resistant oil is adjusted to 800 mg / L±50 mg / L. Then, 200.0 g of the phosphate fire-resistant oil is placed in a conical flask, the cleaned spiral copper wire is placed in the conical flask, and a ground stopper is put on the conical flask. Then, the conical flask is placed in an oven at 115°C±1°C, and aged in the oven for 164 hours. After the aging is completed, the conical flask containing the sample is taken out, and after cooling to room temperature, the acid value and resistivity of the oil sample are detected.

[0067]

[0068] As shown in Table 1, the changes in the acid value and resistivity of oil sample A in the closed cup aging test method are smaller than those of oil sample B, indicating that the stability of sample A is better than that of sample B. The acid value and resistivity change trends of oil samples A and B in Examples 1 to 12 of the present invention are consistent with those of the closed cup aging method, that is, the acid value increases and the resistivity decreases, and the acid value and resistivity changes of oil sample A are both smaller than those of sample B, which also indicates that the stability of sample A is better than that of sample B. That is, the results obtained by the microwave catalysis method of the present invention are consistent with those obtained by the prior art method, and the detection cycle is shortened from 164h to 40min, which greatly reduces the time required for the test.
