Problems solved by technology
There are following disadvantages in this dehydration method: on the one hand, due to the anhydrous CaCl 2 The density of the particles is greater than that of fuel oil, and they will settle at the bottom of the dehydration container, and cannot be in good contact with the fuel oil. It must be stirred continuously to achieve a good dehydration effect, which is time-consuming and labor-intensive.
However, the device has a complex structure and is not suitable for the dehydration detection of a small amount of water-containing fuel oil in petroleum testing laboratories
At present, research on small dehydration devices for fuel oil containing water in petroleum testing laboratories has not been reported

Embodiment Construction
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0024] The applicant's laboratory was classified as a national key laboratory for petrochemical product testing by the General Administration of Quality Supervision, Inspection and Quarantine in 2003. It mainly undertakes the import and export of petroleum products at various ports in Shandong Province and the testing business entrusted by the society. The applicant has been engaged in petroleum product testing for more than 9 years, and has a relatively comprehensive understanding of the performance, indicators and how to dehydrate fuel oil containing water.
[0025] Such as figure 1 As shown, a small water-containing fuel oil dehydration device used in a petroleum testing laboratory includes a pressure system, a drying cylinder 1 surrounded by a stainless steel outer wall, a...

The invention discloses a small dehydrating device of water-containing fuel oil for a petroleum detection lab. The device comprises a pressure system, a temperature control system, a drying barrel defined by a stainless steel outer wall and a filter system mounted in the drying barrel; a cone-shaped funnel is arranged at the bottom of the drying barrel, an oil filling hole and a ventilating hole are formed in a top plate of the drying barrel, and a pluggable seal rubber stopper is arranged on the oil filling hole; the pressure system comprises an air compressor which is inserted into the ventilating hole through a ventilating pipe to pressurize the drying barrel, a pressure gauge and a pressure regulating valve are arranged on the ventilating pipe; the filter system is composed of a stainless steel filter screen and an anhydrous calcium chloride filter layer; and the temperature control system comprises an insulating layer wrapping the outer wall of the drying barrel, and the insulating layer is filled with heat-isolating quartz cotton. The dehydrating device disclosed by the invention is simple in structure, small in occupied area and suitable for use in a petroleum lab.
Description
technical field [0001] The invention belongs to the technical field of fuel oil dehydration equipment, and in particular relates to a small water-containing fuel oil dehydration device used in petroleum testing laboratories. Background technique [0002] Many fuel oils contain a certain amount of water in petroleum product testing laboratories. If the water content is too high, it will inevitably affect the detection of its physical and chemical indicators. For example: ①When the moisture content of fuel oil is greater than 0.2mass%, when testing its kinematic viscosity (100°C), the fuel oil in the viscosity tube is discontinuous due to the volatilization of water, which makes the detection impossible; ②When testing the fuel oil containing water During the decompression distillation process, if the moisture content is higher than 0.5mass%, the presence of moisture will cause the sample to boil violently, resulting in unstable pressure and even affecting the accuracy of the i...
