Abstract

The present invention discloses an oil-gas separation cylinder, an oil-gas separation device and an oil chromatography. The oil-gas separation cylinder comprises an oil-gas separation cylinder body of which axe extends in direction of up and down, a separating block which separates the oil-gas separation cylinder body into an upper cavity and a lower cavity, an oil-gas separation cylinder piston movably installed in the lower cavity, an oil inlet passage and an oil outlet passage, and an oil-gas separation cylinder vent arranged at upper end of the upper cavity, wherein both of the oil inlet passage and the oil outlet passage are communicated with the upper cavity, wherein the separating block is provided with a guiding hole and a spaying hole used to communicate the upper cavity to the lower cavity, or the separating block is provided with a spaying hole guiding oil used to communicate the upper cavity to the lower cavity. By motion of an oil-gas separation cylinder piston, oil is spayed so as to rapidly realize equilibrium of oil and gas. Deaerating space is dynamically expanded so as to strengthen deaerating effect. The present invention adopts vacuum spraying method, but eliminates a mixer motor which continuously stirs the oil. Thus, structure of the oil-gas separation device is simplified.

First claim

What is claimed is:

1. An oil-gas separation cylinder comprising:
an oil-gas separation cylinder body of which axe extends in a vertical direction;
a separating block which separates the oil-gas separation cylinder body into an upper cavity and a lower cavity;
an oil-gas separation cylinder piston movably installed in the lower cavity;
an oil inlet passage and an oil outlet passage, both of which are communicated with the upper cavity; and
an oil-gas separation cylinder vent arranged at upper end of the upper cavity;
wherein the separating block is provided with a guiding hole and a spaying hole used to communicate the upper cavity to the lower cavity, or the separating block is provided with a spaying hole guiding oil used to communicate the upper cavity to the lower cavity.

2. The oil-gas separation cylinder of claim 1 , wherein the oil-gas separation cylinder body further comprises: an upper cylinder body and a lower cylinder body, both of which are fixed on the separating block; both of the oil inlet passage and the oil outlet passage are arranged at the separating block.

3. The oil-gas separation cylinder of claim 1 , comprising:
an oil returning tube installed onto the separating block extending upward to the upper cavity;
an oil returning tube inlet arranged at upper end of the oil returning tube communicating with interior of the oil returning tube; and
an oil returning passage arranged at the separating block communicating with the oil returning tube to deliver oil in the oil returning tube out through the upper cavity.

4. The oil-gas separation cylinder of claim 3 , wherein the oil returning passage is communicated with the oil outlet passage to deliver the oil in the oil returning tube out through the upper cavity.

5. An oil-gas separation device comprising:
an oil-gas separation cylinder, and
a plenum cylinder;
wherein the oil-gas separation cylinder further comprising:
an oil-gas separation cylinder body of which axe extends in direction of up and down;
a separating block which separates the oil-gas separation cylinder body into an upper cavity and a lower cavity;
an oil-gas separation cylinder piston movably installed in the lower cavity; an oil inlet passage and an oil outlet passage, both of which are communicated with the upper cavity; and
an oil-gas separation cylinder vent arranged at upper end of the upper cavity;
wherein the separating block is provided with a guiding hole and a spaying hole used to communicate the upper cavity to the lower cavity, or the separating block is provided with a spaying hole guiding oil used to communicate the upper cavity to the lower cavity;
wherein the plenum cylinder further comprising:
a plenum cylinder body;
a plenum cylinder piston arranged in the plenum cylinder body;
a plenum cavity enclosed by the plenum cylinder piston and the upper section of the plenum cylinder body for gathering gas;
a plenum cylinder inlet and a plenum cylinder outlet, both of which are arranged at the plenum cylinder body and communicated with the plenum cavity;
wherein the plenum cylinder inlet is communicated with the oil-gas separation cylinder vent.

6. The oil-gas separation device of claim 5 , wherein the oil-gas separation cylinder body with separation structure comprises an upper cylinder body and a lower cylinder body, both of which are fixed on the separating block; both of the oil inlet passage and the oil outlet passage are arranged at the separating block.

7. The oil-gas separation device of claim 5 , further comprising:
an oil returning tube installed onto the separating block extending upward to the upper cavity;
an oil returning tube inlet arranged at upper end of the oil returning tube communicating with interior of the oil returning tube;
an oil returning passage arranged at the separating block communicating with the oil returning tube to deliver oil in the oil returning tube out through the upper cavity.

8. The oil-gas separation device of claim 7 , wherein the oil returning passage is communicated with the oil outlet passage to deliver the oil in the oil returning tube out through the upper cavity.
