Description

The oilcan dehydration device

Technical field

The utility model provides the oilcan dehydration device that petrochemical industry is used for deviating from from the oil product jar moisture.

Background technology

The oil product that contains moisture in the oil product jar advances jar after static water-oil separating, and the water that wherein contains can sink to pot bottom gradually, jar interior water of deviating from of not timing.Before the utility model proposes, the oil storage tank bottom is connected with discharging valve, after oil product stays for some time in tank body, at the bottom of depositing in water is gone into jar, by manually opening discharging valve, by oil-containing whether in the eye-observation discharge water, because the profit boundary has the emulsification transition zone, human eye is difficult to judgement, so, in the water discharge process in the tank body, easily oil product is discharged, oil leak accident but also contaminated environment not only occur.The Artificial Control labour intensity that discharges water is big, and working condition is poor, and elapsed time is many, especially is difficult to control the process of discharging water and takes the phenomenon of oil product out of and take place.

Summary of the invention

In order to overcome the shortcoming of existing oil dehydrating equipment, the utility model proposes the oilcan dehydration device.This dehydrator solves the technical problem of deviating from moisture from oil product by the body value of weighing is judged.

The scheme that the utility model technical solution problem is adopted is: be provided with the dehydrator chamber in the dehydration body, inside spin is arranged with heat-exchange tube in the dehydrator chamber, its two ends go out pipe with steam inlet tube and steam respectively and are connected, the dehydrator bottom is provided with sewage draining exit, top is provided with the oil phase tube connector, downside at dehydrator is connected with water inlet pipe, on upside or oil phase tube connector, be connected with outlet pipe, bottom at the opposite side of dehydrator is connected with adjutage, discharging valve is installed on it, tangential angle is connected with the profit inlet pipe at the middle part of dehydrator, the middle part is provided with the weighing filler ring on dehydrator, LOAD CELLS is connected with the filler ring contact, is connected with the Weight acquisition controller by lead between discharging valve and LOAD CELLS.

Effect of the present utility model is that draining cuts oil, detects in the oil tank whether the water of transfiniting is arranged, if there is the water of transfiniting to discharge automatically, the no visible oil bloom that dewater are closed discharging valve automatically after water has been arranged, and does not have oil and discharges.Characteristics are: (1) utilizes to weigh to judge in the jar whether the water of transfiniting is arranged accurately, and working stability is reliable.(2) dehydrator has profit secondary separation effect, is rotated separating oil and water in dehydrator, and oil is overflowed back in the jar by the top, and water is discharged.(3) can guarantee safety dehydration by control of Weight acquisition controller and demonstration dehydration, avoid the dehydration accident.Suiting to deviate from petroleum refining process moisture uses.

The specific embodiment

According to shown in Figure 1, in dehydration body 1, be provided with device chamber 2, inside spin is arranged with heat-exchange tube 15 in the dehydrator chamber, its two ends go out pipe 7 with steam inlet tube 6 and steam respectively and are connected, the dehydrator bottom is provided with sewage draining exit 3, top is provided with oil phase tube connector 11, downside at dehydrator is connected with water inlet pipe 4, on upside or oil phase tube connector, be connected with outlet pipe 5, bottom at the opposite side of dehydrator is connected with adjutage 9, discharging valve 10 is installed on it, tangential angle is connected with profit inlet pipe 8 at the middle part of dehydrator, the middle part is provided with weighing filler ring 12 on dehydrator, and LOAD CELLS 13 is connected with the filler ring contact, is connected with Weight acquisition controller 16 by lead between discharging valve and LOAD CELLS.

Go out on pipe, water inlet pipe and the outlet pipe to be separately installed with stop valve at steam inlet tube, steam.

With connect by flexible hose respectively on the pipeline that body is connected.

The dehydrator filler ring is connected with the LOAD CELLS contact.

The utility model course of work:

Install:

Water inlet pipe is connected with water receptacle respectively with outlet pipe, in the disposable use of timing signal.

The oil phase tube connector is connected by metal hose with oil tank.

Steam inlet tube and steam go out pipe and are connected with the external steam pipeline respectively by flexible hose, to medium companion heat in the dehydrator.

The profit inlet pipe is connected by flexible hose with petroleum tank.

Adjutage is communicated with cesspool.

The Weight acquisition controller receives the gravimetric value signal of Weight acquisition controller, drives the switching of discharging valve according to the numerical value of predetermined weight value by pressure switch, and discharging valve adopts magnetic valve.

Use:

1, dress water is weighed, and by water inlet pipe water filling in the dehydrator chamber, when water level reaches from position that outlet pipe flows out, stops water filling, unties the waterflood-transmission line that is connected with the device chamber, weighs up the weight of the water of packing in body and the device chamber by weighing, as the reference standard value.

2, oil tank passes through quiescent setting, form water layer below, the water layer part flow in the dehydrator chamber with tangential direction by the profit inlet pipe, and flow out by adjutage, standard value and the value of weighing comparison this moment according to prior demarcation, the value of weighing drives discharging valve and opens more than or equal to standard value, emits the isolated water of bottom outside dehydrator.Stop to discharge water during setting value when the weight of body reaches predefined, drive discharging valve and close.Because oil is different with the proportion of water, oil product swims in the upper strata, and depositing in water drops to lower floor.The oil on upper strata flow in the oil tank by oil phase tube connector self-pressing type, realizes the profit secondary separation, reaches the purpose of oilcan dehydration.

Sewage draining exit is used for the dirt that the displacer chamber is accumulated.

When dehydrator normally uses, disconnect water inlet pipe and the outlet pipe of demarcating usefulness.

Because profit inlet pipe and device chamber are tangential direction and enter into the dehydrator chamber, are subjected to the mobilization of its fluid, and oil and water in the dehydrator chamber are rotated, and produce centripetence, help the secondary separation of oil and water.

Heat-exchange tube carries out heat exchange with medium in the device chamber, improve the temperature of oil product and water, prevents the oil product retrogradation or solidifies, and helps separating of oil product and water, and water is deviate from by the bottom, and oil turns back to oil tank by the oil phase tube connector.

The utility model dehydrator can carry out intellectual monitoring and automatically control, thereby realizes unattendedly, and draining cuts oil automatically, eliminates oil and the contaminated environment accident of running.Reduce hand labor intensity, reach the specification requirement of oil tank automatic dehydration.
