Description

Positive-pressure high-efficiency gas-liquid separator

Technical Field

The utility model relates to a vapour and liquid separator, in particular to a positive pressure high-efficiency vapour and liquid separator for producing in industrial production.

Background

The separation principle of the gas-liquid separator in the existing industrial production has two types: the mixture is separated by utilizing the difference of the component mass (weight). The density of the gas is different from that of the liquid, and the mass of the gas is smaller than that of the liquid in the same volume. The mixture is separated by using the size difference of the dispersion particles. The liquid has a different molecular aggregation state from that of the gas, the gas molecules are far away, while the liquid molecules are much closer, so that the gas particles are smaller than the liquid particles. The separation requirement is relatively low, and gravity settling separation is selected. The separation requires that, in general, either ordinary baffled separation or ordinary centrifugal separation is selected. And the requirement is higher, centrifugal separation and filler separation are selected. The requirement is high, and the silk screen separation is selected. The requirement is high, and the microporous filtration separation is selected. Gravity settling: because the density of the gas is different from that of the liquid, when the liquid flows together with the gas, the liquid is subjected to the action of gravity to generate a downward speed, the gas still flows towards the original direction, namely the liquid and the gas have the tendency of separating in a gravity field, and the downward liquid is attached to the wall surface and is gathered together to be discharged through a discharge pipe. Baffling and separating: when the liquid and the gas flow together due to different densities, if the gas and the liquid meet barriers, the gas can be deflected away, and due to inertia of the liquid, the forward liquid is attached to the barrier wall surface, is gathered together downwards due to the action of gravity, and is discharged through a discharge pipe. Centrifugal separation: because the density of the gas is different from that of the liquid, when the liquid and the gas are mixed and flow together, the centrifugal force applied to the liquid is larger than that of the gas, so that the liquid has the tendency of centrifugal separation, and the liquid is adhered to the separation wall surface, is gathered together downwards due to the action of gravity and is discharged through a discharge pipe. Screen mesh separation: because the gas and the liquid have different particle sizes, when the liquid and the gas are mixed and flow together, the gas passes through, and the liquid is intercepted and remained on the wire mesh and flows to the bottom of the separator to be discharged under the action of gravity.
