Description
Technical field:
The utility model belongs to oil storage tank machinery cleaning field, oil field, particularly a kind of positive negative suction system that is used to clean oil storage tank.
Background technology:
At present, the viscosity of crude of Daqing oil field output is generally higher, and being cleaned oil tank also is unwashed for many years oil storage tank, sewage settling tank mostly, and jar end Residual oil viscosity is very big, and oily relative density is big, and is mobile poor.Therefore clear jar of equipment suction of an existing mechanical handover ability is explained inadequately for the very big oil of viscosity, causes tank-cleaning operation to be subjected to very big influence.In the mechanical cleaning construction of oil storage tank, the way of recycling of oil has two kinds in cleaning the storage at present: the one, and the mode of employing vavuum pump, filter, Trinity jar and the supporting recovery of centrifugal pump; The 2nd, adopt oil-gas mixed delivery pumps such as displacement pump or screw pump, utilize the negative pressure that himself forms that the oil in cleaning the storage is reclaimed.More than two kinds of ways of recycling for oil better, Oil Recovery rate that viscosity is lower is higher, but surpasses 300mm for viscosity
2The recovery of the sticking oil of/s, super sticking oil then can not effectively be carried out, and can't pump out or transships phenomenon through regular meeting.
Summary of the invention:
In order to solve the problem that exists in the background technology, the utility model provides a kind of positive negative suction system that is used to clean the storage, this device can the bigger liquid of transport viscosity, and the phenomenon that motor overheating transships can not appear, solves the bigger oil of mechanical clear jar of process medium viscosity and transferred difficult problem.
The technical scheme that the utility model adopted is: this positive negative suction system that is used to clean the storage comprises the volume jar, described volume jar is two, two corresponding ends of volume jar seal respectively and are communicated with feed line, admission line and vacuum lines, valve C I and valve C II are installed on the feed line, feed line between valve C I and the valve C II is connected with the oil tank that is cleaned, valve B I and valve B II are installed on the admission line, the pressure jar that prestores is installed on the admission line of valve B I and valve BII, the pressure sealing that prestores jar is communicated with pressure fan, valve A I and valve A II are installed on the vacuum lines, vacuum-pumping tube linear sealing between valve A I and the valve A II is communicated with vavuum pump, the other end sealing of two volume jars is communicated with delivery pipeline, sealing is communicated with flowline on the delivery pipeline, valve D I and ball-and-seat G I are installed on the delivery pipeline of flowline one side, valve DII and ball-and-seat G II are installed on the delivery pipeline of flowline opposite side.
This novel beneficial effect that has is: this novel employing vacuum system mode that combines with the gases at high pressure force feed, oil in the negative pressure of utilizing vavuum pump to produce will clean the storage pumps out to the volume jar, the gases at high pressure that utilize air compressor to produce are transferred away the oil in the volume jar, whole process does not have oil pump to participate in, be applicable to that various viscositys clean the storage, avoided because of the high problem of can't transferring that produces of oil viscosity, overload problem, accessory damage problem, system power problems of too, the recovery ability can reach 40m
3/ h.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-volume jar, 2-vavuum pump, 3-pressure fan, the 4-pressure jar that prestores, 5-valve A I, 6-valve A II, 7-valve B I, 8-valve B II, 9-valve C I, 10-valve CII, 11-valve D I, 12-valve D II, 13-ball-and-seat G I, 14-ball-and-seat G II, 15-valve.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
This novel 2 volume jars 1, vavuum pump 2 and valve C I 9, valve C II 10, valve A I 5 and valve A II 6 are connected together by pipeline is as shown in Figure 1 formed vacuum system.This vacuum system is to be beforehand with what a base, all equipment installations are all put on this base, import barrier valve C I 9, valve C II 10 are installed on the feed line, and the feed line between valve C I 9 and the valve C II 10 is connected with the oil tank that is cleaned; Valve A I 5, valve AII 6 these 2 by-pass valve controls are installed on the vacuum lines, and valve A I 5, valve A II 6 link to each other with vavuum pump 2 by vacuum lines, produce negative pressure by the gas in the vavuum pump 2 suction volume jars 1.Valve D I 11, valve D II 12 these 2 control of export valves are installed on the delivery pipeline of liquid outlet in the volume jar 1, ball-and-seat G I 13, ball-and-seat G II 14 are installed respectively between valve D I 11, valve D II 12 and the volume jar 1, make the liquid of volume jar 1 can only lean on this delivery pipeline to flow out, extraneous liquid can not flow to the volume jar 1 from this delivery pipeline; In addition, need mounted valve B I 7, valve B II 8 at each volume jar 1 tank deck, during on-the-spot assembling, valve B I 7, valve B II 8 need to connect pressure and prestore jars 4.
Pressure fan 3 and pressure prestored jars 4 to be connected together by pipeline and to form gases at high pressure force feed system, as shown in Figure 1.The gas that pressure fan 3 produces enters pressure by pipeline and prestores in jars 4.During on-the-spot assembling, pressure prestored jars 4 links to each other the continuity of assurance air feed with the valve B I 7 that gets ready in advance, valve B II 8 usefulness admission lines.
As previously mentioned, positive negative suction system mainly is to play a role by 2 volume jars 1 and vavuum pump 2, utilize negative pressure that the oil in the jar is pumped out, again with gases at high pressure with the oil pressure of volume jar 1 to receiving tank, in order to improve handover efficient, the volume tank volume can not be too small, this device volume jar inner volume is 2 cubic metres, diameter is 1500mm, adopt double-layer sleeve structure, thickness of interlayer is 50mm, walks steam in the interlayer, can not solidify to guarantee that oil product enters in the volume jar 1, have certain heat effect simultaneously.Unobstructed in order to guarantee that oil product enters volume jar 1 pipeline, this device is provided with 2 pipelines that feed the volume jar.This device adopts water ring vacuum pump 2, and power is that the by-pass valve control that this device of 15KW. adopts is pneumatic ball valve.Emptying valve 15 is installed on the volume jar 1.
During actual the use: the suction mode adopts 2 pairs of volume jars 1 of vavuum pump to aspirate, and volume jar 1 is formed negative pressure, utilizes the oil of volume jar 1 negative pressure in will cleaning the storage to aspirate out to volume jar 1; The handover mode adopts air compressor that gas pressure is prestored to inject gases at high pressure in jars 4, by the control valve group prestore jar 4 inner high voltage gases of pressure are injected in the volume jar 1, pressure prestores, and the pressure of gases is transferred to the oil in the volume jar 1 in the receiving vessel in jars 4.Idiographic flow is as follows:
Now all valves are in closed condition, open valve A I 5 and valve C I 9, vavuum pump 2 effects, gas in the volume jar 1 in left side is found time, crude oil enters in the volume jar 1 in left side through valve C I 9, when arriving the highest liquid level, valve C I 9 and valve A I 5 close, pressure fan 3 effects, valve B I 7, ball-and-seat G I 13 and valve D I 11 open, the crude oil of the volume jar 1 in left side flows out through ball-and-seat G I 13, valve D I 11, and liquid level arrives minimum point in jar, and ball-and-seat G I 13 and valve D I 11 close; Valve A II 6 and valve C II 10 open simultaneously, vavuum pump 2 effects, gas in the volume jar 1 on right side is found time, crude oil enters in the volume jar 1 on right side through valve C II 10, when arriving the highest liquid level, valve C II 10 and valve A II 6 close, pressure fan 3 effects, valve B II 8, ball-and-seat G II 14 and valve D II 12 open, and the crude oil in the volume jar 1 on right side flows out through ball-and-seat G II 14 and valve D II12.So repeatedly, finish whole flow process.
Whole process automaticallyes switch, goes out to establish the hand-guided switch at control panel, but manual adjustments port opening time length.
