The control part is mainly characterized in that a buffering air bag (1) is connected to the side of a natural gas inlet pipeline, a contact sliding block (6) and a liquid level bag (5) are installed at the top of the buffering air bag (1), the contact sliding block (6) is installed on a guide rail (4), 4 explosion-proof limit switches (3) are installed in the guide rail (4), and the explosion-proof limit switches (3) are respectively connected with relevant parts of an air exhaust part. The oil tank volatile gas recovery device can automatically give an alarm, supplement gas, stop and empty, and can adjust the air extraction speed according to the change of gas flow.
Description
The utility model relates to natural fuels and reclaims the field.
The Volatile Gas in Oil Tank regenerative apparatus mainly partly was made up of the partial sum backflow tonifying Qi of bleeding in the past, the part of bleeding comprises: oil water separator, natural gas compressor, intake and exhaust shutoff valve group, metrical instrument and discharging valve group, backflow tonifying Qi part is made up of reflux valve and reflux pipeline, the reflux pipeline inlet end with efflux pipeline and join, the reflux valve outlet is joined with oil water separator, opens the reflux valve tonifying Qi when tolerance diminishes.A big jar Volatile Gas is a kind of unstable source of the gas, its fluctuation of pressure is irregular variation, be in slight positive pressure state, the backflow air compensating system only plays the tonifying Qi effect when tolerance reduces, in use, when tolerance raises, can not bleeding regulating speed, can't learn the speed of evacuation whether with the Volatile Gas amount phase equilibrium, especially come oil mass too high when the place ahead, liquid level sharply rise and big jar of urgent draining situation under or reflux valve be in malfunctioning state, can not avoid occurring taking out the danger of flat big jar and drum jar.
The purpose of this utility model be to design a kind of can auto alarm in pumping process, tonifying Qi, shutdown and emptying, and can be according to the Volatile Gas in Oil Tank regenerative apparatus of the variation bleeding regulating speed of tolerance.
The utility model is made of the partial sum control part of bleeding, the part of bleeding comprises: with the oil water separator that comes the tracheae line to connect, the natural gas compressor that admission port connects by pipeline and oil separator outlet, the metrical instrument that communicates with natural gas compressor outlet and discharging valve group respectively, on the pipeline between metrical instrument and the natural gas compressor, reflux pipeline is housed, reflux pipeline joins through self-supporting control cock and by pass line and oil water separator, control part is the center with the buffer air bag, the contact slide block of horizontal positioned is housed at the buffer air bag top, fixing liquid level bag on the slide block of contact, the liquid level bag is respectively by the film head of pressure guiding pipe and self-supporting control cock and the pressure transmission device of instrument cabinet, automatically the emptying electro connecting pressure gauge joins, sliding being installed in soon in contact is equipped with in the guide rail of putting quick-fried limit switch, guide rail becomes vertical direction with buffer air bag with the contact slide block, explosion-proof limit switch and control housing join, control housing links to each other with natural gas compressor, emptying electro connecting pressure gauge and control housing join, control housing links to each other with the emptying butterfly valve, pressure transformer is linked to each other with frequency converter by signal wire (SW), frequency converter links to each other with natural gas compressor with control housing, and the natural gas compressor of the buffer air bag of control part and the part of bleeding also connects and communicates with oil water separator.
The utility model is owing to used buffer air bag, buffer air bag volatile quantity when fluctuation in jar, height with volatilization tolerance, drive contact slide block and the liquid level bag on it move up and down, and with the height of movement position, the pressure signal of liquid level bag output increases or reduces, and the contact slide block is also with the difference of position and the high position on the guide rail, most significant bit simultaneously; Low level, the explosion-proof limit switch of lowest order contact; put quick-fried limit switch signal is delivered to control housing; control housing is carried out corresponding the demonstration and action; realize warning, emptying or shutdown; the signal that the liquid level bag flows to instrument cabinet divides two the tunnel, the one tunnel to flow to pressure transformer, converts electric signal to by pressure transformer and is defeated by frequency converter and control housing; to adjust the speed of evacuation, volatilization tolerance and swept volume are balanced each other.Flow to the signal of emptying electro connecting pressure gauge and self-supporting control cock, when buffer air bag moves to the control most significant bit, the electric contact pressure list index overlaps with desired location, and contact output signal in contact is opened emptying by control housing commander emptying electromagnetic valve, resets after the disengagement most significant bit; When air bag moves to lowest order, the pressure signal of liquid level bag output acts on pressure on the self-supporting control cock film head less than setting value, return-flow system is opened tonifying Qi, go up to guarantee jar internal pressure, prevent to take out the generation of flat phenomenon, emptying simultaneously and backflow air compensating system have manual nature concurrently, under the situation that autonomous cruise speed system breaks down, still can guarantee big jar safety.
Embodiment of the present utility model provides in conjunction with the accompanying drawings.
Accompanying drawing is a Volatile Gas in Oil Tank regenerative apparatus section-drawing.
