3When Pa) working long hours continuously under the situation, air-flow is gone out exhaust outlet with 18～24 meter per second speed, high velocity air makes the pump oil in the fuel tank splash, pressure in the fuel tank is higher relatively again simultaneously, high velocity air carries the oil droplet that splashes and is sprayed by exhaust outlet, become oily line formula ejection when serious, pollute environment and consume pump wet goods consequence fast, big-and-middle-sized pump and high speed unit contruction pump are particularly serious.
In order to solve the above-mentioned oil spout problem of oil seal type rotating machinery vavuum pump, usually the technical measures of taking at present have following several: 1, increase volume of fuel tank as far as possible, to reduce the relative pressure in the fuel tank, slow down the air velocity of exhaust, but increased the volume and the weight of pump when increasing volume of fuel tank, and fundamentally do not solved the oil spout problem; 2, devices such as additional oil guard, oil cleaner screen, the high velocity air that carries oil droplet is by these devices the time, though said apparatus can block or the filtration fraction oil droplet, high velocity air also can be taken away the part oil droplet on these devices simultaneously, and gas-flow resistance is big; 3, increase gs-oil separator, in the conventional gs-oil separator filter screen or adsorption stuffing are arranged all, complex structure safeguard inconvenience, and gas-flow resistance is big.
Summary of the invention
Technical problem to be solved by this invention is to overcome the defective that above-mentioned prior art exists, provide a kind of reasonable in design, easy to maintenance, gas-flow resistance is little, the cyclone separating gas oil separator of good separating effect.
For this reason, the present invention adopts following technical scheme: cyclone separating gas oil separator, comprise housing and the conduit that is connected housing top, one top cover is arranged at the top that it is characterized in that described housing, this top cover connection one is positioned at the central blast pipe of housing center, the bottom of housing has an oil outlet that is positioned at central blast pipe below, and the inwall on the gas outlet of conduit and housing top is tangent.The present invention directly is connected with the exhaust outlet of oil seal type rotating machinery vavuum pump, after high velocity air is gone out exhaust outlet, directly contacts with the oily nothing of the pump in the fuel tank, avoids high velocity air directly to contact pump oil and makes the pump oil in the fuel tank splash.The high velocity air (oil droplet that brings from lubricated, the oil sealing of pump etc.) that contains oil droplet enters cyclone separating gas oil separator along conduit with tangential direction, most of gas is done top-down rotatablely moving around axis between housing and central blast pipe, fraction moves upward, and turns back in most of gas behind the chance top cover.Because the proportion of oil is much larger than the proportion of gas, under the effect of high speed centrifugation power, the oil droplet in the air-flow is thrown toward inner walls, flows out from oil outlet at last, flows in the fuel tank that is installed in the cyclone separating gas oil separator bottom; The center of clean gas turns housing in the swirling eddy is subjected to stopping of bottom fuel tank pasta and returns, and forms the eddy flow of one rising, discharges through the gas outlet of central blast pipe.
Described cyclone separating gas oil separator, the air inlet of central blast pipe is lower than the gas outlet of conduit, has prolonged the path of gas in separator, and it is longer to make most of gas do the top-down time that rotatablely moves around axis, and oil gas separation is better.
Described cyclone separating gas oil separator, conduit are 90 degree bend pipes, have more than two; The number of conduit is an even number, and symmetry is installed on the housing, and is reliable and stable when making gs-oil separator work.
Described cyclone separating gas oil separator, central blast pipe are straight tube or conical tube, and preferred up-small and down-big conical tube can make the mist of oil of discharging in the gas be attracted on the inwall of central blast pipe.
Described cyclone separating gas oil separator, housing is truncated cone, and is up big and down small, and housing also can adopt cylindrical certainly.Columniform relatively housing, the housing that is truncated cone is more excellent in the effect of gs-oil separator.
The present invention has following beneficial effect: reasonable in design, and gas-flow resistance is little, handles large-mindedly, easy to maintenance, can separate the above oil droplet of 0.05mm; The path length of gas in separator, good separating effect, air-flow has not after treatment had macroscopic oil droplet, has only light mist of oil.
