Abstract
The utility model relates to a jet-type oil gas recycling system. The jet-type oil gas recycling system comprises a hydraulic injector, an adsorption tank and an exhaust funnel, and further comprises a separation tank. Volatile gas in an oil tank or a hole tank directly enters into the adsorption tank which is in an adsorption state, or enters into the adsorption tank which is in the adsorption state after passing through the separation tank. Cleaned gas after being adsorbed is discharged by the exhaust funnel. At the same time, a certain vacuum degree is achieved in the absorption tank through the hydraulic injector, wherein the absorption tank is in a regeneration state. Oil gas which is absorbed by absorbing mediums was desorbed by vacuum. The desorbed high-thick oil gas is absorbed into the hydraulic ejector, and enters into the oil tank or the hole tank after being mixed with oils in an oil-injection pipeline. Thus gas oil recycling of an entire oil-injection process is finished. The jet-type oil gas recycling system uses energy of an oil-injection system, and has the advantages of simple equipment, easy operation, low energy consumption and small maintenance quantity.

Preferably, this system also comprises separating tank, and the oil gas inlet of separating tank is connected with the gas-phase space of hole jar or oil tank, and the gaseous phase outlet after the separation is connected to the oil gas inlet of absorption canister.The liquid phase outlet of separating tank is connected to hole jar or oil tank, so that liquid phase is from flowing to hole jar or oil tank.The quantity of absorption canister is two or more, and when system works, wherein at least one absorption canister is in running order, and other absorption canisters are in reproduced state.Adsorbing medium in the absorption canister is active carbon or silica gel.The pipeline that is connected between hydraulic ejector, separating tank, absorption canister and the aiutage is provided with by-pass valve control, and being connected the vacuum desorption pipe of absorption canister and the valve on the pipeline between the hydraulic ejector is check valve.Hydraulic ejector is venturi-type eductors, aiutage and atmosphere.
The utility model utilizes the hydraulic ejector on the oiling pipeline to produce certain degree of vacuum, realizes the vacuum desorption to absorbent charcoal adsorption tank.Total system does not have mechanical equipment and consumer, and energy source has made full use of the energy of injection system itself in the residual head of oiling pipeline.Have the following advantages:
Except that control system, no energy consumption equipment, energy consumption level is low;
Except that control instrument, there is not explosion-proof problem in the unregulated power device;
Compare with the conventional gas and oil regenerative apparatus, saved absorption tower, vacuum pump, rich solution oil pump etc., total system is simplified greatly, and occupation of land less, system is simple, running gear is few, maintenance workload is few.
Description of drawings
Fig. 1 is the system schematic of the utility model.
Main label declaration among the figure:
1 hydraulic ejector, 2 separating tanks, 3 absorption canisters, 4 aiutages.
The specific embodiment
Below in conjunction with accompanying drawing, further specify the specific embodiment of the utility model.
Shown in accompanying drawing 1, system of the present invention comprises: hydraulic ejector 1, separating tank 2, absorption canister 3 and aiutage 4.The adsorbing medium that active carbon or silica gel etc. are suitable for adsorbing oil gas is housed in the absorption canister 3.
Hydraulic ejector 1 is installed on the oiling pipeline of hole jar or oil tank; The vacuum desorption pipe of absorption canister 3 be connected on hydraulic ejector 1 by ejecting port; The oil gas inlet of absorption canister 3 communicates with hole jar or oil tank gas-phase space, and the gas discharge outlet of absorption canister 3 is connected to aiutage 4.This system also comprises separating tank 2, and the oil gas inlet of separating tank 2 is connected with the gas-phase space of hole jar or oil tank, and the gaseous phase outlet of separating tank 2 is connected to the oil gas inlet of absorption canister 3.The liquid phase outlet of separating tank 2 is arrived hole jar or oil tank through plumbing connection.The quantity of absorption canister 3 is two or more, and when system works, wherein at least one absorption canister 3 is in running order, and other absorption canisters 3 are in reproduced state.Adsorbing medium in the absorption canister is active carbon or silica gel.The pipeline that is connected between hydraulic ejector 1, separating tank 2, absorption canister 3 and the aiutage 4 is provided with by-pass valve control, and being connected the vacuum desorption pipe of absorption canister 3 and the valve on the pipeline between the hydraulic ejector 1 is check valve.Hydraulic ejector 1 is a venturi-type eductors, aiutage 4 and atmosphere.
