Description
Technical field
The utility model belongs to fuel oil dehydration equipment technical field, and in particular to a kind of for oil testing laboratory
The small-sized dehydration device of aqueous fuel oil.
Background technology
Many fuel oil all contain a certain amount of moisture in oil product testing laboratory, if the too high gesture of moisture
The detection of its physics and chemical index must be influenceed.Such as：1. when fuel oil moisture is more than 0.2mass%, it is being detected
During kinematic viscosity (100 DEG C), make the fuel oil in viscosity tube discontinuous due to moisture evaporation, so as to cause detection not carry out；
2. during the vacuum distillation range of detection aqueous fuel oil, if moisture is higher than 0.5mass%, due to the presence of moisture
Sample can be made acutely to seethe with excitement, so as to cause pressure transient or even the accuracy of initial boiling point can be influenceed.Therefore, to aqueous fuel
Oil carries out that before the detection of some projects dewater treatment must be carried out.
Fuel oil dewater treatment has a variety of methods, for oil product testing laboratory using most methods be by
Anhydrous CaCl2Particle is distributed in fuel oil, is constantly stirred, and makes water adsorption in fuel oil to CaCl2Particle surface,
So as to reach dehydrating effect.Had the disadvantage that using this dewatering：On the one hand, due to anhydrous CaCl2The density of particle
More than fuel oil, the bottom of dewatering container can be deposited in, it is impossible to contacted well with fuel oil, it is necessary to continual stirring ability
Reach preferable dehydrating effect, take time and effort.On the other hand, anhydrous CaCl2More fuel oil can be remained between particle, for sending
The situation of sample size deficiency occurs in the less sample of sample amount.Carried out further, sample is poured out into dewatering container after dehydration
During detection, anhydrous CaCl2Particle is easily mixed into detection sample, also influences whether to detect the accuracy of data.Also,
Because some fuel oil easily solidify, i.e., pour point is too high, if not using temperature control system, fuel oil can go out during dehydration
Situation about now solidifying, therefore, it must be dehydrated for the higher fuel oil of pour point in the state of certain temperature is kept.
There is part instrument producer the country, as what Heze new century instrument company produced a kind of ' medium-sized ' is directed to aqueous fuel
The dehydration device of oil.Disposably dehydration needs more than 2 liters of fuel oil to the device, and its dewatering Principle is to make fuel using heat temperature raising
Water and light component volatilization in oil, then make light component backflow realize dehydrating effect.Will certainly in this dehydration
The loss of part light component in fuel oil is caused, is changed the composition of sample, influences whether the accuracy of testing result.
The A of patent of invention CN 103396830 disclose a kind of heavy dirty oil dehydration device and method, and area's sump oil enters after drawing
Y-type filter, 80~130 DEG C are warming up into vapor heat exchanger (1) after booster pump is pressurized after filtering, then introduce eddy flow and take off
Hydrophone (2) is separated into low aqueous sump oil phase and low oil-polluted water phase, wherein low water sump oil mutually enters coalescence dehydrator (4) further
Dehydration, obtain low wet oil and ejector；Low oil-polluted water phase, which then enters in degreaser cyclone (3), simultaneously is divided into High water cut dirt
Oil phase and sewage phase, sewage are mutually discharged, and High water cut sump oil, which then circulates, does dewater treatment.The invention realizes the company of heavy dirty oil dehydration
It is continuous to carry out, and carry out deep dehydration and depth de-oiling simultaneously and thorough part dehydration cycle can be separated, apparatus and method energy
Consume that low, easy to operate, dehydration rate is high, to various water content, the heavy dirty oil strong adaptability of containing filth amount, be adapted to the weight larger to quantity
Sump oil carries out long-term disposal.But the apparatus structure is complicated, a small amount of aqueous fuel oil in oil testing laboratory is not appropriate for
Dehydration detection.At present, in oil testing laboratory aqueous fuel oil small-sized dehydration device research there is not yet reporting for work.
