Description

Compressed air oil-water separator Technical Field The invention relates to the technical field of inverter manufacturing, in particular to a compressed air oil-water separator. Background The compressed air oil-water separator is a gas-liquid separator for compressed air, which is not used for separating oil and water, but is used for separating condensed water, oil and other impurities in the compressed air, so that the compressed air is primarily purified. The separated oil and water are discharged from the sewage outlet together. The use pressure is not limited generally, and the use temperature should be at normal temperature. The QF gas-liquid separator has the working principle that when compressed air enters the oil-water separator, the flow direction and the speed change rapidly, and then oil drops and water drops with the density higher than that of the compressed air are separated by virtue of centrifugal action. Common impact type and annular rotary oil-water separators. After the compressed air enters the separator shell from the inlet, the air flow is impacted by the baffle plate and turned back downwards, and then rises upwards again to generate annular rotation. Therefore, water drops and oil drops are separated out from air under the action of centrifugal force and inertial force and are settled at the bottom of the shell, and the water drops of the oil drops can be discharged by periodically opening a bottom valve. The air after preliminary purification is sent to an air storage tank from an outlet; When the existing compressed air oil-water separator adopts an annular rotary structure, the impact is blocked by the baffle plate to turn back downwards, then the impact is turned back upwards, and annular rotation is generated, so that water drops and oil drops are separated out from air under the action of centrifugal force and inertial force and are settled at the bottom of the shell, and the water drops and the oil drops naturally flow out only by reducing the air pressure in the tank during collection and discharge, so that the cleaning is periodic, the production plan is easy to make, and the influence on the working efficiency is reduced; However, in the practical application process, even though the periodic discharge is performed, stains are generated on the inner wall of the tank body due to the change of temperature, so that the compressed air is secondary-polluted, the later cleaning working time is prolonged, the periodic discharge is only suitable for air with specified humidity, when the air humidity exceeds a threshold value, the liquid in the tank can be easily and rapidly increased when the air humidity is overlong, the air pressure in the tank is further rapidly changed, the centrifugal space of the compressed air is reduced, and the oil-water separation efficiency of the compressed air oil-water separator and the service life of the tank body are further reduced.
