Description
Relate to the field:
The utility model relates to the oilcan dehydration technology, specifically, is a kind of oilcan dehydration automatic control device.
Background technology
At present, general oil product is stored in the oil tank, contain a certain amount of water in the oil product, through an end after the time, water will be separated from oil product gradually, because the density of water is greater than oil, oil slowly rises, and water is sedimentation gradually, thereby forms apparent in view oil-water interface in oil tank, existing oilcan dehydration adopts the ponding in the manual method eliminating oil tank, in drainage procedure, unavoidably can cause the part oil product to run off like this, not only cause energy loss to a certain extent, also can cause environmental pollution, artificial anh work capacity is also bigger simultaneously.
Technology contents
The purpose of this utility model is to provide a kind of second dehydration that can realize oil tank, and implements automatic guidance, reduces oil product and runs off, energy savings, a kind of oilcan dehydration automatic control device of minimizing environmental pollution.
The utility model is achieved in that and comprises storage tank 1 coolant inlet pipe 2, flood valve 3, detection instrument 4, cable 5, display instrument 6, power supply 7, drain hose 8, control cock 9, source of the gas 10, hand valve 11,12, dehydration canister 13, reflux valve 14, counter flow pipe 15, be connected to coolant inlet pipe 2 on the storage tank 1 respectively, counter flow pipe 15, pass through coolant inlet pipe 2 on one side between storage tank 1 and the dehydration canister 13, flood valve 3 is communicated with, another side is by counter flow pipe 15, reflux valve 14 is communicated with, power supply 7 makes detection instrument 4 by cable 5, display instrument 6 connects successively, be communicated with by hand valve 12 between dehydration canister 13 and the control cock 9, control cock 9 is communicated with by hand valve 11 with source of the gas 10, and the sidepiece of control cock 9 has drain hose 8.
The utility model also adopts following technical scheme:
Be connected with detection instrument 4 by cable 5 on the dehydration canister 13, detection instrument 4 can enter the bottom of dehydration canister 13.
The bottom of storage tank 1 is connected with the top of dehydration canister 13 by coolant inlet pipe 2 and flood valve 3.
The top of dehydration canister 13 then is connected with oil product storage tank 11 bottoms by counter flow pipe 15 and reflux valve 14.
Advantage of the present utility model is: can realize remote auto control, reduce labor intensity of operating personnel, improve the automatization level of tank field, because the oil product that human element caused runs off, save the energy in the minimizing dehydration, reduce environmental pollution simultaneously.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Concrete enforcement
As shown in the figure, the bottom of oil product storage tank 1 is connected with the top of dehydration canister 13 by coolant inlet pipe 2 and flood valve 3, the top of dehydration canister 13 then is connected with oil product storage tank 11 bottoms by counter flow pipe 15 and reflux valve 14, oil water interface detector 4 canister 13 bottoms of deeply dewatering, measure the oil-water interface level value in the dehydration canister 13, and signal is passed to display instrument 6 by cable 5, display instrument 6 is according to measured level value, send corresponding signal to control cock 9,13 drainings of control dehydration canister, power supply 7 is display instrument 6 power supplies, source of the gas 10 is control cock 9 air feed by hand valve 11, above-mentioned each pipeline and dehydration canister 13 are equipped with mixes hot line and insulation, and heat tracing when being used for winter low temperature can guarantee total system normally operation throughout the year.
In the course of the work, at first power supply 7 and source of the gas 10 are opened, then flood valve 3 and reflux valve 14 are opened, the water (or oil water mixture) in the oil product storage tank 1 flows into dehydration canister 13 by coolant inlet pipe 2, carries out secondary separation in dehydration canister 13.Along with the water yield that flows in the dehydration canister 13 increases, oil-water interface rise, when rising on the display instrument 6 predefined liquid levels, oil-water interface prescribe a time limit, display instrument 6 sends signal to control cock 9, control cock 9 is opened, and the water of dehydration canister 13 bottoms is discharged by drain hose 8 through hand valve 12 and control cock 9.The oil product on dehydration canister 13 tops then flows back to oil product storage tank 1 through counter flow pipe 15.The aperture of control hand valve 12 makes the water inlet simultaneously in the process of slowly draining of dehydration canister 13, make the liquid level of oil-water interface remain a steady state value, and control cock 9 is in opening all the time, has realized, the three-dimensional continuity of draining.Three-dimensional water has been arranged in oil product storage tank 1, and flowing into whole in the dehydration canister 13 is oil product, and oil-water interface drop to the liquid level lower limit of setting, and control cock 9 is closed, and stops draining.Wherein display instrument 6 and power supply 7 are installed on operator's compartment, and above-mentioned all the other each parts all are installed on by the on-the-spot oil product storage tank in tank field, thereby realize Long-distance Control.
