Description
Technical field
The utility model relates to Investigation of Petroleum Vapor Recovery Technology field.
Background technology
At petroleum chemical industry, the loss not only contaminated environment of oil product, be unfavorable for health, and it is inflammable and explosive, easy breaking out of fire, if this part volatile oil gas collection is got up, not only increase economic efficiency, and protection of the environment, oil gas is namely mixed with the air of volatile oil, its usual recovery method is dissolved in solvent by absorption tower by oil gas, the material that can hold with oil phase usually chosen by solvent and density ratio oil is large, like this can by solvent and the upper and lower multi_layer extraction of oil through sedimentation after dissolving oil gas, but because oil gas is gas shape, oil gas not easily thoroughly dissolves totally by the solvent in absorption tower, absorption efficiency is low, and space for sedimentation below absorption tower is little, the multi_layer extraction of solvent and oil is unfavorable for after solvent and oil dissolve mixing, inferior separating effect.
So need now a kind of device to solve the problem, can be good at carrying out solution absorption to oil gas, and sedimentation separation space is large.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of petroleum vapor recovery absorption plant, and oil gas absorbing can dissolve by this device effectively, and absorption efficiency is high.
The technical scheme taked for the utility model that solves the problem is: a kind of petroleum vapor recovery absorption plant, this device comprise absorption tower and with the knockout drum be communicated with bottom absorption tower, air inlet is provided with bottom described absorption tower, top is provided with gas outlet, in the inside on absorption tower along absorption tower short transverse repeating successively be provided with multiple oil gas absorbing unit be interconnected, described oil gas absorbing unit comprises about the symmetrical inferior pyramidal chamber of horizontal plane and inverted upper conical chamber, be interconnected by less end opening between described inferior pyramidal chamber and upper conical chamber, the inwall in inferior pyramidal chamber is provided with multiple jets of solvent, described jets of solvent is communicated with the solvent inlet on the outer wall of absorption tower.
Preferably, be interconnected by hole of confluxing between the less end opening in described inferior pyramidal chamber and the less end opening in upper conical chamber.
Preferably, between the inwall and the outer wall on absorption tower in upper conical chamber, be provided with annular chamber, described annular chamber is communicated with the solvent inlet on the outer wall of absorption tower, is communicated with between described annular chamber with the jets of solvent on inferior pyramidal cavity wall by infusion channel.
Preferably, described knockout drum is horizontal tank.
The beneficial effect adopting technique scheme to produce is: be provided with multiple oil gas absorbing unit in the absorption tower of this device, can repeatedly absorb oil gas from top to bottom, and oil gas absorbing unit is made up of upper conical chamber and inferior pyramidal chamber, inferior pyramidal chamber is provided with jets of solvent, jets of solvent is connected with annular chamber by infusion channel, in annular chamber, solvent is injected by solvent inlet, jets of solvent can be made to spray solvent, oil gas is dissolved, inferior pyramidal chamber is in the taper of shrinking gradually from top to bottom, oil gas is amassed wealth by heavy taxation gradually, be conducive to the spray of solvent to oil gas, the solvent dissolved after oil gas is trickled down in the upper conical chamber of lower floor's oil gas absorbing unit, thus solvent is amassed wealth by heavy taxation and flow to inferior pyramidal chamber by hole of confluxing, can proceed to absorb together with the oil gas of novel solvent to lower floor of inferior pyramidal chamber ejection and dissolve, so repeatedly operate, greatly can improve the solution absorption effect of solvent, so the absorption efficiency of this absorption tower to oil gas is high, solvent obtains abundant recycling, and the design of pyramidal structure is more conducive to collecting of oil gas and absorbs, the knockout drum of bottom is horizontal tank, volume and sectional area are all larger, be conducive to a large amount of solvents with oil is carried out to sedimentation and is separated.
