Description
Technical field
The present invention relates to oily water separation technique field, be specially a kind of dewater unit and use the oil conditioner of this device and continuous predrainage method.This device a kind of to be metalled run out the too high oil product pretreatment of fault, the water content such as (snow), steam leakage of raining and the special equipment that designs for equipment specially.
Background technology
Lubricating oil, hydraulic pressure wet goods oil product, in the process used, inevitably by the various impurity produced in surrounding environment and in system work process, as pollutions such as dust, moisture, abrasive dust and greasy filth, cause oil product deterioration, environmental pollution, the wasting of resources.In order to change this state, the dewatered clean of oil product is very important.
In oil purification process, may due to equipment metal run out fault, rain the factor such as (snow), steam leakage, cause water content in pending oil product too high, even occur based on water, only containing a small amount of oil condition, oil purification is made to be difficult to carry out smoothly.Prior art, mainly for the technology of carrying out containing a small amount of water in oil product processing, removes the moisture in oil product as methods such as utilization heating, filter core, centrifugal force.If the too high oil product of water content does not carry out any process directly pass into oil conditioner, increase huge burden by dehydration equipment, a large amount of water, at oil conditioner Inner eycle, occupies the dischargeable capacity of dehydration equipment, reduce the utilization rate of dehydration equipment, increase difficulty and the cost of oil dehydrating.
For the problem that moisture of oil pending in oil purification process is too high, current major measure is settling methods, namely relies on gravity to make it disperse according to water-oil phase density difference, thus reaches the object of water-oil separating.There is following outstanding drawback in this way:
1. need to shut down process, production can not be carried out continuously
In actual production process, once occur that equipment such as to be metalled run out at the fault, modal method shuts down process; pending oil product is introduced in displacement can sedimentation a period of time, the proportion difference according to profit carries out layering, after water-oil separating; opening discharging valve by observing oil water surface, discharging end water.This processing method has had a strong impact on the normal operation normally using and produce of oil conditioner.And if do not shut down, make pending oil product directly enter displacement can, Momentum Transfer and buoyancy can make oil-water interfaces fluctuate in a big way, even cannot determine oil-water interfaces, cause the moisture of oil after process too high, do not reach pretreated effect; Also can contain a large amount of oil product in the end water of discharging, cause unnecessary loss to user, cause environmental pollution simultaneously.
2. need enough settling areas and sedimentation time
Obviously, the efficiency of settling methods is very low, need the standing sufficiently long time on the one hand, profit just can be made automatically to be separated, on the other hand particle diameter is less than to the emulsification state drop of 100 μm, simple settling methods does not act on, and particularly oil-water mixture is very easy to form stable oil-in-water or Water-In-Oil structure, emulsion occurs, and this situation will make the more difficult separation of oil-water mixture.Produce actual heat and expect a kind of continuous seepage and water-oil separating efficiently and dewatered clean equipment.
