The gravity type gas-liquid separator is the most common gas-liquid separator, and the principle of the gravity type gas-liquid separator is that liquid is settled and flows out from a water outlet at the lower part by utilizing the difference between the settling speed of the liquid and the rising speed of the gas, and the gas is discharged from an air outlet at the upper part, so that the gas-liquid separation is realized. The separation method is simple and quick, but the gas-liquid separation effect is not very ideal, and the separated gas still contains a large amount of moisture. There is therefore a need for improvements to existing gas-liquid separators. Generally, the air inlet pipe of the gas-liquid separator is of a straight-through type, namely, the section of the air inlet pipe extending into the gas-liquid separator is a straight-through connecting pipe, the position of an air outlet of the air inlet pipe is lower than that of an air inlet of the air outlet connecting pipe, but the entering gas-liquid mixture directly impacts bottom liquid, and the gas-liquid separation effect is influenced. For improving the separation effect, the utility model discloses a toper distribution baffle formula vapour and liquid separator has been designed at the gas-liquid mixture entrance point, the L shape baffle that the gas-liquid mixture striking toper distributes, gaseous upwards through the silk screen defroster by upper end gas outlet discharge, liquid gets into the collecting tank downwards, by lower extreme liquid outlet discharge. The utility model discloses can separate multiple gas-liquid two-phase fluid to have separation effect good, efficient advantage.

SUMMERY OF THE UTILITY MODEL
