Aviation kerosene storage tank capable of preventing microorganism breeding

Abstract

The invention discloses an aviation fuel storage tank capable of preventing microbial growth, comprising a tank body, an automatic water cutter is provided at the bottom of the tank body, a nitrogen pipe is provided at the top of the tank body, and a Self-operated pressure regulating valve. The invention utilizes the function of replacing gas with nitrogen to completely replace the humid air in the tank in time, effectively preventing the growth of microorganisms, and simultaneously monitoring the conditions of the medium around the bottom of the tank in an all-round way, effectively avoiding water, external dust, fiber and other sundries The impact on the quality of aviation fuel, and low cost, high efficiency, good safety performance, to ensure the high quality of coal, it is worthy of widespread promotion.

Description

technical field [0001] The invention relates to a storage tank, in particular to an aviation fuel storage tank capable of preventing the growth of microorganisms. Background technique [0002] Aviation kerosene, the full name of aviation kerosene, also known as aviation fuel and jet fuel, is a transparent liquid blended from straight-run distillate, hydrocracking and hydrofining components and necessary additives. Aviation kerosene is mainly used as fuel for aviation turbine engines, so there are many and strict quality indicators. Aviation fuel needs to go through multiple links such as production, reconciliation storage, and delivery. The process is long and the quality must be guaranteed. Once the production link is done well, the storage link is particularly important later. Once the storage is not done properly and the protection is not good, it may lead to problems in product quality. [0003] At present, most aviation fuel storage tanks are image 3 As shown, in the...

AI Technical Summary

Problems solved by technology

Once the production link is completed, the storage link is particularly important. Once the storage is improper and the protection is not good, it may cause problems in product quality.

[0003] At present, most aviation fuel storage tanks are image 3 As shown, in the storage tank with inner floating roof, the tank wall is provided with a ventilation hole connected to the atmosphere, and the bottom of the tank is provided with an automatic water cutter near the pumping outlet. The aviation fuel storage tank with this structure has the following defects: First, the storage tank There is no drying device in the tank. When the temperature warms up, especially when the coastal areas "return to the south" in March and April, humid air enters the inner wall of the tank and forms water droplets to flow to the floating plate, which is mixed into the jet fuel, resulting in the growth of microorganisms and reducing the aviation efficiency. Second, although there is an automatic water cutter at the bottom of the tank near the water outlet, which can cut off the water near the water outlet, there is still water around the bottom of the tank, and the storage tank is large in size, so the water can be cut automatically There is only one device, which cannot monitor the tank bottom medium in real time and deal with it in time, which will affect the quality of jet fuel

However, cutting water and prolonging the settlement time can only treat the symptoms but not the root cause. Although cleaning the tank can completely solve the problem, it takes a long time and the cost is high (it takes about 20 days to completely clean a jet fuel tank, and the cost is about 200,000 yuan)
