Description
Technical field
The utility model relates to a kind of system and device of oil and grease dewaxing technology.
Background technology
Oil and grease dewaxing is the conventional process in the oils production process, and the main effect of dewaxing is higher fatty acid and the high fatty alcohol of removing in the oil, and is wherein maximum with high fatty alcohol content.The factor that influences dewaxing technique mainly contains several aspects: a. grease temperature and rate of cooling, and b. grease crystallization time, c. grease stirring velocity, the d. grease is carried and separate mode, the greasy quality of e..
Usually in the grease dewaxing technique, the filtering mode of grease is to adopt the motor high speed rotating of oil pump, grease is transported in the flame filter press, forms filtering under pressure, carry out the effect of solid-liquid separation, but in the grease course of conveying, unfavorable factor has 2 points: the first, and when regulating the pressure backflow, the grease temperature is raise, exceed the crystalline temperature, cause oil can't separate with wax coexistence liquid state.The second, in the high speed rotating process of pump, the xln of wax is formed tiny particle by broken ring, in filtration procedure, is easy to see through filter cloth or filter paper, makes the dewaxing failure.The wax phenomenon appears leaking.Be mixed together out with oil.The quality of oil is reduced, cause crystallization again to be filtered.
Summary of the invention
The purpose of this utility model is in order to promote that wax xln not exclusively broken ring in course of conveying falls in the grease, filter in the dewaxing process thereby reach that the wax xln filters out fully, separates fully with grease.Want wax is separated from grease fully, must guarantee that xln destruction ratio reduces.
In the system and device of the utility model oil and grease dewaxing technology, refrigeration system links to each other with salt water tank, and the chilled brine pipeline is connected to the winterization jar, and the bottom oil outlet of winterization jar is connected to flame filter press, the corrected oil tube for entering can is connected to storage tank, and the storage tank bottom connects lead line; Slops tube for entering can line is connected to the material loading pipeline; Oilless air compressor is connected to the winterization jar by pressure line.Winterization jar bottom oil outlet is connected in the pipeline of flame filter press stand-by pump is set.
System mainly is the pressure that forms by oilless air compressor in process of production, forms pressure difference in entire equipment, impels grease to come out by Plate Filtration.Xln destruction ratio in course of conveying is far smaller than the ratio of utilizing oil pump to carry.Utilizing the xln destruction ratio of the conveying of pneumatics is about 30%, and the destruction ratio of the conveying of usefulness oil pump is more than 90%.
Concrete processing step of the present utility model is as follows:
The first step: pressed oil material loading
At first, reserve the material loading amount, will be with the dewaxing grease to inject surge tank earlier, observe the liquid level of surge tank, how prevented in the surge tank on the oil, cause oil from surge tank, to overflow; After material loading is finished, close feeding pump and material loading valve;
Second step: add flocculating aids
Surge tank begins to stir, and adds flocculating aids in surge tank, and back oil-feed in the winterization jar stirs;
The 3rd step: refrigeration crystallization
In the winterization jar, open the fuel charging valve door switch of winterization jar during oil-feed, open feeding pump, begin oil-feed, observe the fluid position in the surge tank during oil-feed, prevent oil pump idle running, burn-down of electric motor by the material loading pipeline; After oil-feed finishes, close the switch and the oil-feed valve of feeding pump, the oil in the winterization jar begins to refrigerate crystallization; Crystallization is more than 12 hours, and refrigerating temperature is 5-10 ℃ and dewaxes;
The 4th step: filter dewaxing
Open the delivery valve of this winterization jar, jar interior other each valve and a manhole are closed tight; Open oilless air compressor and in jar, feed pressurized air, jar interior pressure is slowly risen by pressure line; On the fuel-displaced pipeline stand-by pump is set, uses when going wrong in order to air compressor machine; Oil after the crystallization flows out from delivery valve, enters flame filter press, observes fuel-displaced situation of flame filter press oil duct and pressure condition, just initiation pressure is not too big, impels filter cloth or filter paper to form filter membrane, and pressure too conference makes filter effect bad, cause wax to overflow, reduced greasy quality; Along with cere progressive additive and the fuel-displaced reduction of oil duct, pressure is along with increase, but can not surpass 0.25Mpa, and concrete pressure bears degree of pressure according to flame filter press and decides size; After oil in the hold-up vessel filters and finishes, continue to filter the oil in the next storage tank, good record filters based on the material loading of record in proper order, and the situation very fast to filtration velocity will have the special messenger to keep an eye on;
The 5th step: drain the oil
Corrected oil after the filtration enters in the processed oil storage tank, and underproof oil returns in the winterization jar again; After treating to deposit about 1/2 in the processed oil storage tank, begin to drain the oil, the oil after advancing in the bucket necessarily posts label, annotates a name still number, the name of an article, and lot number, date, and teams and groups, in bucket, feed nitrogen simultaneously, prevent that peroxide value from raising; When putting outside oil product is placed on, must be neat; Shallow for color depth, content, the different oil product of acid number must SD Chu, and other puts, and performs record simultaneously.
The beneficial effects of the utility model are: system is provided with oilless air compressor, pressure by oilless air compressor formation, form pressure difference in entire equipment, impel grease to come out by Plate Filtration, xln destruction ratio in course of conveying is far smaller than the ratio of utilizing oil pump to carry.
