Description

Technical Field

[0001] The utility model belongs to the technical field of crude oil dehydration, in particular to a dehydration alarm device for a crude oil dehydration tank. Background Art

[0002] Crude oil extracted from wells generally contains a certain amount of water. Excessive water content in crude oil will cause waste in storage and transportation, increase equipment, and consume more energy. Most of the water in crude oil contains salts, which will accelerate the corrosion of equipment, containers, and pipelines. During the oil refining process, when water and crude oil are heated together, the water will rapidly vaporize and expand, and the pressure will rise, affecting the normal operation of the refinery and product quality, and even causing an explosion. Therefore, before exporting crude oil, it is necessary to dehydrate it so that the water content does not exceed 0.5%.

[0003] Crude oil dehydration refers to the process of removing water in the crude oil in a free state or in an emulsion state by physical or chemical methods to make the water content reach the specified standard. There are several methods, such as sedimentation dehydration, thermochemical sedimentation dehydration, and electrochemical combined dehydration.

[0004] In response to this problem, dehydration alarm devices based on photoelectric technology have been developed in the prior art (publication numbers CN210123400U and CN210122558U). These two technologies respectively set a laser transmitter and a laser receiver on both sides of the crude oil output pipeline. When the crude oil passes through the pipeline position where the alarm device is located, it can efficiently and sensitively detect and alarm. Although the detection principle is relatively mature, these two technologies both adopt a fixed installation structure, which is not convenient for the inspection personnel to carry out flexible installation and disassembly on site with the handheld device, nor is it convenient to adjust the position of the device outside the pipeline. In this case, how to develop a portable crude oil dehydration tank dehydration alarm device that is more convenient to hold and install and disassemble on site is a technical problem to be solved in this field.
