Non-detonating after oil gas compression, to be easier to condense, recyclable device be second level cascade refrigeration, cost of investment and operating cost compared with
It is low, the design in carbon adsorption circuit so that petroleum vapor recovery efficiency more preferably.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model condensation adsorption formula device for recovering oil and gas.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, with
Lower embodiment combination attached drawing 1 is specifically addressed condensation adsorption formula device for recovering oil and gas provided by the utility model.
It refering to fig. 1, is the structural schematic diagram of condensation adsorption formula device for recovering oil and gas.It and is the knot of clear display the present embodiment
Structure feature is omitted in figure and shows part-structure, and arrow direction shown in figure indicates the flow direction of oil gas and coolant.
As shown in fig. 1, condensation adsorption formula device for recovering oil and gas provided by the utility model includes being sequentially connected logical delay
Rush tank 1, roots blower 2, fire arrester 3, level-one evaporative condenser 4, dual evaporation condenser 5, gas-liquid separator 6 and oil storage tank
7, wherein level-one evaporative condenser 4 is connected as the evaporator of level-one refrigeration system by stage compressor 41, first-stage condenser
42, level-one throttle valve 43 form level-one refrigerating circuit, between level-one evaporative condenser 4 and dual evaporation condenser 5 connection by
The second level refrigerating circuit that split-compressor 51, secondary condenser 52, two-step throttle valve 53 form；In 4 liang of level-one evaporative condenser
The oil inlet and oil outlet at end are sequentially connected by two triple valves and are returned by the carbon adsorption that vacuum blower 81, adsorption tanks 8 form
Road is equipped with active carbon in adsorption tanks 8, and oil gas is via oil outlet, the first triple valve 91, vacuum blower 81, adsorption tanks 8,
Two triple valves 92 pass back into level-one evaporative condenser 4.
Based on the above-mentioned technical proposal, the oil gas gathered first pass through surge tank 1, roots blower 2, fire arrester 3 boost it is laggard
Enter the level-one evaporative condenser 4 of first order refrigeration system, preliminary most of oil gas after cooling enters second level refrigeration system
Secondary evaporimeter enters oil storage tank 7 through gs-oil separator after oil gas condensation, and entire refrigeration system is folding type cooling system,
First order refrigerant is ethylene, and second level refrigerant is methane, and ethylene enters first-stage condenser after level-one refrigeration compressor
42, after level-one throttle valve 43, subsequently into the cooling oil gas of level-one evaporative condenser 4 and methane；Methane is passing through two-stage compression
Enter secondary condenser 52 after machine 51, the level-one evaporative condenser 4 for entering back into first order refrigeration system is further cooling, then
