Detailed Description

The utility model discloses, as shown in fig. 1, 2, a vapour and liquid separator with vacuum pump protect function, including air inlet 1, gas outlet 2, leakage fluid dram 3, liquid guiding gutter 4, a section of thick bamboo interior discharge tube 5, filter screen 6, catheter 7, barrel 8, washing shower nozzle 9, concrete structure as follows: the air inlet 1 is arranged on the side wall of the barrel, a liquid guide pipe 7 arranged below a liquid guide groove 4 in the barrel is connected with the bottom of the liquid guide groove 4, the section of the liquid guide groove 4 is L-shaped, the liquid guide pipe 7 is arranged along the inner wall of the barrel 8, an air outlet 2 is arranged above the center of the barrel, an air collecting pipe 5 in the barrel and arranged below the air outlet 2 is also arranged at the center of the barrel 8, the bottom of the air collecting pipe 5 in the barrel is a filter screen 6, a cleaning spray head 9 is further arranged inside the air collecting pipe 5 in the barrel, a liquid discharge port 3 is further arranged at the center of the bottom of the barrel, and the liquid discharge port is just below the air collecting pipe 5 in the barrel.

The bottom of the gas collecting pipe 5 in the cylinder is arranged above the bottom of the liquid guide pipe 7.

The air inlet 1 is arranged at a position tangent to the outline circle of the cylinder 8.

The utility model discloses a theory of operation is: after gas and liquid enter the cylinder body 8 tangentially, the liquid is collected into the liquid diversion trench 4, the liquid is guided to the lower part of the gas-liquid separator by the liquid guide pipe 7, the gas leaves the diversion trench 4 and flows downwards to the gas collecting pipe 5 in the cylinder, the inlet of the gas collecting pipe 5 in the cylinder is higher than the bottom of the liquid guide pipe 7, the gas basically does not contact with the liquid flowing out of the liquid guide pipe 7, and the liquid can be ensured to flow out from the liquid discharge port 3 smoothly. Although most of the liquid flows out of the liquid guide pipe 7, a small amount of liquid drops enter the gas collecting pipe 5 in the cylinder along with the gas, at the moment, the filter screen 6 can block the liquid drops entering the gas collecting pipe in the cylinder, the gas mist discharged from the gas outlet 2 is ensured to be carried at a minimum, and the liquid blocked by the filter screen 6 can flow out of the liquid discharge port 3. After the gas-liquid separator operates for a period of time, the filter screen 6 can be cleaned by hot water sprayed by the cleaning spray head 9. The equipment is simple in internal structure, filtrate scabs cannot cause large influence on the equipment, each part is easy to replace, the manufacturing cost is low, and the maintenance is easy.
