Rack comprises installs stand, instrument cabinet, panel, for installation pipeline, components and parts, cable and display instrument.Rack adopts stainless steel moveable structure, and outside surface is provided with electrostatic spray layer.
Working process of the present utility model and principle as follows.
As shown in Figure 1, remove by ball valve GV-1 after the impurity that may exist through gas filter F-2 after source nitrogen (purity >=99.5%) and equipment connection, then through being adjusted to suitable pressure (0.4MPa) by air inlet reducing valve PSV-1.Then accurately control gas flow by mass-flow gas meter FT/FV, enter line mixer H by fixed flow rate.Magnetic valve BV-1 is the normally closed solenoid valve controlled by mass-flow gas meter, only have under meter to open magnetic valve BV-1 simultaneously just to open, corrosion damage under meter in gas meter is entered to prevent the gas-oil mixture in follow-up pipeline from pouring in down a chimney, ball valve GV-2 is to the special valve of oil tank inflated with nitrogen, manually opened when needing.
First the oil entering filtering accuracy 5 μm after fuel source and equipment fuel filler connect filters filter F-1 and removes the particulate matter that may contain, to be pressurizeed by pump P-1 after ball valve GV-3 and through liquid mass flow meter FI coutroi velocity, magnetic valve BV-2 is the normally closed solenoid valve controlled by liquid mass flow meter, only have liquid mass flow meter to open magnetic valve BV-2 simultaneously just to open, flow backwards to prevent the fuel oil in follow-up pipeline.
Fuel spray after making pressurization containing high pressure spray nozzle in venturi mixer PZ is that grade small droplets enters in mixing tank, and then with the nitrogen mixing entered in mixing tank, atomization can increase gas-to-liquid contact face area, makes mixing more abundant.
Fuel and nitrogen are fully mixed with nitrogen by static pipeline mixer H after venturi mixer, dissolved water in fuel oil and dissolved oxygen are reallocated between fuel oil and nitrogen, finally reach balance, to mixing tank end, most dissolved oxygen and dissolved water enter into nitrogen.
As shown in Figure 1, static pipeline mixer makes fluid reach mixing.Left-handed when static pipeline mixer makes fluid, time and dextrorotation, constantly change flow direction, not only core flow pushed to periphery, and peripheral fluid is pushed to center, thus cause good radial mixed effect.Meanwhile, the turning effort of fluid self also can occur on the interface of adjacent component junction, and this perfect radial circular flow mixing effect makes material acquisition mix, and makes the phase interface of oil-gas two phase component upgrade continuously and fully contact.
Gas-oil mixture is separated by cyclonic separator XF, and the cylindrical tube of cyclonic separator and single conic tube form an eddy flow chamber, and fuel oil is discharged from separator lower end, and enter buffering oil tank V, gas is discharged from the venting port on separator top.The basic functional principle of cyclonic separator utilizes the density difference between gas-liquid to carry out centrifugation.When fuel oil nitrogen mixture enters eddy flow chamber from tangential inlet, in chamber, high speed rotating produces centrifuge field, under centrifugal action, because fuel density is obviously greater than gas so meeting centrifugal settling, move to around, thus along the downward turn of wall, finally discharge as underflow; The nitrogen Ze Hui center that density is little is assembled, and along axis upwards turn, discharges enter oil gas secondary separation tank from overflow port.
Carry a small amount of fuel oil foam nitrogen secretly after the discharge of cyclonic separator XF upper end overflow port, enter oil gas secondary separating system, oil gas secondary separation tank by metal tin and wherein the specific filler piling up mode form, after oil gas secondary separation, fuel oil is directly collected to buffering oil tank V from end opening, and nitrogen is then discharged from the venting port being separated tank body top by spark arrester.As shown in Figure 2, the basic functional principle of oil gas secondary separation tank utilize gas-liquid different densities cause inertia difference realize baffle separation.After the nitrogen carrying fuel oil foam secretly enters secondary oil gas separating tank, because gas is different from the density of fuel oil, when liquid flows together with gas and vapor permeation, stop if run into filler, gas is understood baffling and upwards collects in upper end outlet discharge; And liquid is due to inertia, continue there is a speed forward, liquid is forward attached to and stops on filling surface because the effect of gravity pools together downwards, is discharged by delivery pipe.In oil gas secondary separation tank, piling up of filler is designed to there is certain gap in the middle of tank skin and filler, filler is relatively common baffle separationly to be had much bigger stop and collects wall area, and repeatedly baffling repeatedly, fuel oil is easy to wall, after wall, fuel oil would not touch filler again toward current downflow, just can effectively prevent high-speed gas from being dispelled by the fuel oil secondary collected, therefore its separating effect is obvious.
Delivery system comprises circulation fuel oil treatment and finished product carries two kinds of mode of movements, and circulation fuel oil treatment is, the fuel oil in buffering oil tank V is delivered to circular treatment in mixing system through liquid meter, magnetic valve BV-3 by pump P-2 again; This mode is the filling preconditioned pattern of equipment, for equipment washing; Finished product conveying is, the finished fuel in buffering oil tank V is delivered into finished product fuel tank by pump P-2 after liquid meter, magnetic valve BV-4 are finally by the oil filtration filter F-3 filtration of filtering accuracy 5 μm.
The conveying of fuel oil finished product uses for giving when equipment normally runs during follow-up fuel tank continuous oil supply, and the fuel oil treatment that circulates uses in a case where: device systems needs for some time make gas and liquid flow rate reach preset value and stablize when just starting, use equipment is filled preconditioned pattern one key and is started, controlled circulation magnetic valve BV-3 opens, oil-feed magnetic valve BV-2 and go out solenoid BV-4 and close, and makes the fuel oil in buffering oil tank come back to circular treatment in mixing system until system stability.
The height of liquid level of buffering oil tank V is taken into account transmitter to realize by liquid level, for continuous detecting and record liquid level, transmitting module is coordinated to use, geometric ratio simulation real-time level height, when cushioning oil tank level and reaching certain liquid level, conveying signal control programmable logic controller makes transfer pump carry start and stop; Programmable logic controller can control the rotating speed of transfer pump with the liquid level of liquidometer reaction simultaneously, liquid level higher then transfer pump transfer rate is faster, when there is no fuel oil after fuel liquid level reduces or in storage tank, transfer pump automatically slows down transfer rate or quits work, and so just can effectively prevent transfer pump from dallying.
As shown in Figure 3, biofuel dehydration deoxidation equipment adopts 2 variable-frequency motors, realizes raw material fuel filler and injects and export export with finished fuel, thus reaches and quantitatively export control to finished fuel definite value.
Utility model works mode is divided into manually and control automatically.Automatic control has three kinds of operating mode, i.e. (1) quantitative filling pattern; (2) preconditioned pattern is filled; (3) emptying pattern.By liquidometer, pressure transmitter and liquid meter detection system real-time working condition, through programmable controller PLC calculation process, reach the optimum control of system.
The above know-why being specific embodiment of the utility model and using, any based on the equivalent transformation on technical solutions of the utility model basis, all belong within protection domain of the present utility model.
