Intelligent pipeline type automatic dewaterer for oil tank and pressure tank

Abstract

The invention discloses a smart pipeline type automatic dehydrator of the oil tank and pressure pot, comprising an entrance flange, an outlet flange, a honeycomb duct, a major detecting controller, a minor detecting controller, a major filter, a minor filter, a vapor pipe, a temperature controller, an adjusting valve and a drain-trap. The entrance flange of the honeycomb duct is connected with the spot oil tank, and the outlet flange is connected with the adjusting valve; the sensors of the major and minor detecting controllers are respectively connected with the honeycomb duct, and the major and minor filters are respectively covered on the sensors of the major and minor detecting controllers, the signal outputs of the major and minor detecting controllers are connected with the adjusting valve. Because the dehydrator is connected with the oil tank by the mounting flange, when the size is not suitable, the problem can be solved by adding a converting joint, and the mounting is very convenient. Meanwhile the honeycomb duct adopts a streamline structure, and completely without circulation dead angle. While dehydration, the solid impurity settled in the bottom medium of the dehydrator can be discharged with water without budget in the dehydrator, and the invention has a self rinsing function, and does not need periodical rinsing. The invention is suitable for the automatic dehydration field of oil tank, liquefied gas tank and pressure storage tank of chemical product.

Description

Technical field: [0001] The invention relates to an automatic dehydration device for oil tanks, liquefied gas tanks, and pressure storage tanks for chemical products. In particular, it relates to a new type of intelligent pipeline type automatic dehydrator for oil tanks and pressure tanks. technical background: [0002] Water is the main companion in the oil and gas production process and oil refining production process. Therefore, dehydration and water cutting operations are important tasks in the storage and transportation process. After the crude oil or refined oil is demulsified by physical or chemical methods, the oil and water are automatically layered in the tank due to the difference in density. In order to remove the accumulated water at the bottom of the tank, manual manual dehydration is usually used. During the dehydration process, the operator is required to watch the sewage tank. Because the visual characteristics of refined oil and water are not obvious, it is diff...

AI Technical Summary

Problems solved by technology

Because heavy oil, crude oil and other oil products have similar densities to water, it is difficult to establish a stable oil-water interface during the flow, so the dehydration speed of this type of dehydrator is very small

Crude oil, heavy oil and other oil products pollute the sensor more seriously, so this type of dehydrator can only be used for dehydration of refined oil
