Problems solved by technology

Repeated heating of the oil in the oil tank will produce a large number of fine decomposition products during the heating process, which will have a certain impact on the color quality of the oil and increase the cost of post-processing
[0009] During the use of the built-in oil tank heater, since the tube bundle is inserted into the oil storage tank as a whole, and the medium in the tube is steam, due to metal corrosion, medium scouring and other reasons, it may cause local cracks, pores and other leakage phenomena in the heat exchange tube. , after the rupture, the steam moisture will enter the oil in the storage tank, because the leakage point is inside the equipment, and there are no other effective monitoring methods, it is difficult to detect it in time by manual inspection
Although the probability of leakage is extremely small, once it is leaked, it will bring huge losses to users
Since the lubricating oil has extremely strict requirements on moisture, when the heater in the storage tank leaks, the moisture in the lubricating oil in the storage tank exceeds the standard. Because the cost of treating the lubricating oil moisture is high, it is generally not necessary to treat the moisture exceeding the standard. The lubricating oil is processed, and the lubricating oil is directly returned to the factory, which not only causes a waste of energy, but also pollutes the environment

Abstract

The invention discloses an internal oil tank heating oil product quality control system and a quality control method. The control system comprises a storage tank, a heater arranged in the storage tank, a steam inlet pipeline, a steam outlet pipeline, an oil inlet pipeline and an oil outlet pipeline, wherein the steam inlet pipeline and the steam outlet pipeline are communicated with the heater, and the oil inlet pipeline and the oil outlet pipeline are communicated with the storage tank. The steam inlet pipeline is provided with a steam switching valve, and the oil inlet pipeline of the storage tank is provided with an oil switching valve. The oil outlet pipeline is provided with a water detector. The steam switching valve, the water detector and the oil switching valve are all connected with the control system. When the heater leaks, water, detected by the water detector on the oil outlet pipeline detects, in lubricant oil exceeds the set value, the control system controls the oil switching valve and the steam switching valve on the oil inlet pipe to be closed, and the lubricating oil and the steam stop being supplied at the same time. The internal oil tank heating oil product quality control system is specially suitable for an internal steam heater, automatic monitoring of steam leakage in the lubricating oil heating process can be achieved, and larger losses caused by steam leakage can be effectively avoided.

Description
