Embodiment 2

[0035] In actual production, the working process of the air source oil purification device during heating operation is as follows:

[0036] a) Heating oil temperature to filter impurities

[0037] The oil system valves (1, 10, 9 are open), the other valves are closed, and the oil suction pump is turned on, the oil to be heated in the system passes through the inlet valve (1) → inlet protection filter (2) → oil suction pump (3) → Inlet heat exchanger (4) shell side → impurity filtration system isolation door (10) → fine filter (11) → outlet heat exchanger (8) → outlet door (9) forms an oil circuit circulation. In addition, the compressor (12) runs, and the refrigerant is compressed by the compressor to form a heating cycle. Compressor (12)→isolating door before oil heating (13)→inlet heat exchanger (4) tube side→isolating door after oil heating (14)→throttle device (15)

[0038] → front isolation door of the evaporator (20) → air-cooled evaporator (18) → liquid storage tank (...

Embodiment 3

[0046] In actual production, the working process of the air source oil purification device during cooling operation is as follows:

[0047] Impurities need to be filtered but the system oil temperature is too high and beyond the tolerance range of the filter element

[0048] The oil system valves (1, 10, 9 are open), the other valves are closed, and the oil suction pump is turned on, the oil to be heated in the system passes through the inlet valve (1) → inlet protection filter (2) → oil suction pump (3) → Inlet heat exchanger (4) shell side → impurity filtration system isolation door (10) → fine filter (11) → outlet heat exchanger (8) → outlet door (9) forms an oil circuit circulation. In addition, the compressor (12) runs, and the refrigerant is compressed by the compressor to form a heating cycle. Compressor (12)→isolation door in front of condenser (19)→air-cooled condenser (17)→throttling device (15)→isolation door in front of oil inlet cooling (24)→inlet heat exchanger ...

Abstract

The invention provides an air source oil purification device. The device comprises an oil circulation system and a heating and cooling system, wherein a refrigerant is cooled by a compressor for raising the system oil temperature, or a throttled low-temperature refrigerant is used for lowering the system oil temperature, an air-cooled evaporator and a condenser are used for absorbing or releasingheat into the air to complete heat transfer, and heat transfer of the inlet or outlet oil temperature can also be used. The best oil filtering effect can be achieved without increasing the overall heat of the system.

Description

technical field [0001] The invention relates to the field of oil filtration, in particular to an air source oil purification device. [0002] technical background [0003] Air source oil purification devices are widely used in the fields of liquid purification and environmental protection. [0004] The traditional centrifugal oil filter does not have high dehydration and particle precision, and is generally used when there is a large amount of water and impurities. Suitable for primary or coarse filtration, where a large amount of water is present in the oil. The oil temperature is very critical to the separation effect of water and particles, so the temperature is required to be controlled within a narrow range. The electric heater is one of the necessary components. The 10 tons of equipment per hour is equipped with an electric heater of 60-90KW. Two groups are put in as needed. The existence of the heater is a great safety hazard. The increase in oil temperature will a...
