The upper part and the middle part of an inner cavity of a vacuum tank (13) are respectively provided with a deluge device (12) and a heater (11) which is opposite to the deluge device (12); the bottom of the inner cavity of the vacuum tank is provided with a high oil level switch (34), a low oil level switch (35) and an oil floating valve (33) respectively; an oil inlet (3) is formed in one end of an oil inlet pipeline (36) and the other end of the oil inlet pipeline is connected with the heater (11); the part of the oil inlet pipeline (36) which is positioned between the oil inlet (3) and the vacuum tank (13) is sequentially provided with an electromagnetic valve I (2) and a coarse strainer (1); an oil outlet (4) is formed in one end of an oil outlet pipeline (46) and the other end of the oil outlet pipeline is connected with the vacuum tank (13); an inlet of an oil pump (37) is communicated with the vacuum tank (13); an outlet of the oil pump (37) is connected with an inlet of a secondary filter (38) through a check valve I (42); an outlet of the secondary filter (38) is sequentially connected with a check valve II (30) and a sampling valve (31); the top of the vacuum tank (13) is connected with a condenser (19) through a vacuum pipe (18); and the condenser (19) is connected with a vacuum pump (26) and a water collection box (22) through a conveying pipe I (47) and a conveying pipe II (48) respectively.

Description

Technical field [0001] The invention relates to a combined multifunctional phosphoric acid grease resistant fuel oil purification equipment. Background technique [0002] With the development of large-capacity, high-parameter steam turbine units, the rated pressure of the working medium of the unit's regulating system increases. The requirements for working media are getting higher and higher. To ensure the safe and economic operation of the unit. In the steam turbine adjustment system, phosphate ester fire-resistant fuel is commonly used. Phosphate ester fire-resistant fuel is susceptible to contamination by moisture, temperature, particulate impurities and system materials during long-term operation and maintenance, which affects the performance of the fire-resistant fuel. The safety of the system and the unit is a hidden danger. Unqualified fire-resistant fuel will trip the generator unit and cause the unit to stop. At present, my country's anti-fuel purification equipment ...

AI Technical Summary

Problems solved by technology

Phosphate-resistant fuel is generally used in steam turbine adjustment systems. Phosphate-resistant fuel is easily polluted by moisture, temperature, particulate impurities and system materials during long-term operation and maintenance, which will affect the performance of the fuel and give The safety of the system and the unit has buried hidden dangers. Unqualified anti-fuel will cause the generator set to trip and the unit to stop.

At present, my country's anti-fuel oil purification equipment mainly relies on imports, and the imported equipment has a single function. For example, if the moisture in the oil exceeds the standard, a coalescence separator must be installed to dehydrate it; type oil filter

The oil standard is a comprehensive index, and the operation of single-function equipment cannot meet the requirements of equipment oil
