Detailed Description

The invention is described in further detail below with reference to the figures and the embodiments.

As shown in fig. 1 to 3, the oil-gas separation exhaust cap comprises a riser tube 111 connected with an air outlet of the equipment, a separator 112 for oil-gas separation is arranged on the top of the riser tube 111, and an exhaust pipe 114 is arranged on the top of the separator 112.

Preferably, a plurality of layers of filtering and separating wire meshes 113 are arranged in the separator 112.

Preferably, the bottom of the housing of the separator 112 is provided with a plurality of sieve holes, and the top is an open structure. As shown in fig. 2 and 3, the casing of the separator 112 may have a cylindrical structure, a plurality of sieve holes are formed in the bottom thereof, and the top thereof is open, so that the multi-layered filtering and separating wire 113 can be easily loaded or unloaded.

Preferably, the top of the separator 112 is provided with a butt clamp upper flange 221, the bottom of the separator is provided with a butt clamp lower flange 222, a connecting screw 223 penetrates between the butt clamp upper flange 221 and the butt clamp lower flange 222, and the end of the connecting screw 223 is provided with a connecting nut 224 in threaded fit with the connecting screw. The detachable structure can facilitate the installation and detachment process of the separator 112, and facilitate the maintenance and cleaning process thereof.

More preferably, the clamp upper flange 221 is an annular structure, and an inner ring thereof is installed and matched with the bottom of the exhaust pipe 114.

More preferably, the pair of lower clamping flanges 222 is an annular structure, and an inner ring thereof is installed and matched with the top of the riser 111.

Preferably, the exhaust pipe 114 is of an elbow-shaped structure. As shown in fig. 1, the structure has the functions of dust prevention, rain prevention and the like.

More preferably, an upper seal 225 is provided between the pair of upper clamping flanges 221 and the top of the separator 112.

More preferably, a lower seal 226 is provided between the pair of lower clamping flanges 222 and the bottom of the separator 112.

The working principle of the embodiment is as follows:

in the lubricated equipment of high temperature oil, the position that needs the exhaust is at the exhaust gas in-process, and gaseous emission can accompany oil and follow the discharge, and when the exhaust gas that accompanies oil passes through riser 111, because it keeps away from high temperature position, possesses certain cooling process, and little molecule oil in the exhaust gas can condense into macromolecular oil each other because of the temperature decline, and the exhaust gas flows into separator 112 in, and the space increase when the exhaust gas gets into the separator at riser 111, has the depressurization process, and oil molecule further condenses. At this time, the molecular weight of condensed oil in the exhaust gas is larger than that of gas, a high-density multi-layer filtering separation screen 113 is installed in the separator 112, oil can be attached to the screen when the oil gas passes through the multi-layer filtering separation screen 113, the oil molecules are attached to the screen and aggregated into large oil drops, the oil drops fall into the lifting pipe 111 along the separator 112 under the action of gravity and flow back to the equipment, the oil content attached to the gas is greatly reduced compared with the previous oil content after the exhaust gas passes through the multi-layer filtering separation screen 113, and finally the exhaust gas is exhausted to the atmosphere through an exhaust pipe 114 of an oil-gas separation exhaust cap.
