Description
Technical field
The invention belongs to oil product technical field of memory, specifically, relate to a kind of oil storage equipment filtration drying respiratory system.
Background technology
In the long term storage of oil plant, have and many harmful material of oil product is entered in oil tank by Big and Small Breath, common are moisture, dust and fiber, microorganism and fungi etc.: wherein entering in a large number of moisture can cause microbial contamination, its growth metabolism makes oil quality degradation, for jet fuel, the pollution of microorganism can be stopped up aircraft fuel system, causes aircraft accident, and situation is more severe.
1, moisture: when oil tank is during in vacuum suction state, at this time tank system all can be opened to external world, no matter time length, there is aqueous vapor in capital along with air, enter into oil tank and pipeline, mainly contain the moisture of following several forms: a, fog and rainwater, when raining or hazing, fog or rainwater can naturally be brought in holding vessel along with Tank's Breathing System is air-breathing; B, condensed water, day and night temperature changes the moisture that condensation goes out on the inwall of oil tank mouth or oil tank air intake duct and can enter in oil tank; The steam containing in c, air, air itself has certain humidity, and air humidity, by how many decisions that contain steam in air, therefore, in the time that oil tank is air-breathing, has a small amount of steam to be brought in the lump oil tank.
And research shows that moisture is that necessary condition, the existence meeting of moisture simultaneously that oil product suspension forms causes antioxidant in burn into extracting oil product to oil tank, pipeline, accelerate oil oxidation, greatly shortened, simultaneously for raised growth and the breeding of microorganism provide condition in the oil product storage time limit.
2, dust and fiber: in air, be covered with dust and fiber, particularly in the time that wind-force is larger, more serious. Under severe environment form, fog is also flooded with a lot of areas. And dust and fiber have a strong impact on oil quality, be that microorganism and suspension generate key factor.
3, airborne microorganism and fungi: airborne microorganism and fungi are ubiquitous, when the special larger moisture of humidity is more, can exist in a large number, when microorganism and fungi enter after oil product, can destroy oil quality. And major microorganisms in oil product is all exactly to have in the soil of periphery and air, illustrates that the microorganism in oil product comes from surrounding enviroment.
Comprehensive above factor, in the time carrying out oil product storage, owing to storing a year limit for length, easily be subject to the pollution of moisture, dust, fiber, fungi and microorganism etc., produce the problems such as suspension, corrosion tank, seriously perplexing deposit and the safety of oil plant, therefore need especially a kind of device or system, prevent that moisture, fiber, dust, microorganism and fungi etc. from entering into oil plant memory device, to keep storing oil quality, the burn into that reduces the vitals such as oil tank, pipeline prevents the formation of microbial contamination and suspension.
Summary of the invention
For solving above technical problem, the object of the present invention is to provide a kind of oil storage equipment filtration drying respiratory system, moisture, the fiber dust that can effectively prevent air enter oil storage equipment, can prevent that the microorganism being attached on moisture and fiber dust from entering oil storage equipment, improved the storage life of oil product simultaneously.
