Abstract

The invention relates to an oily water oil content real-time monitoring method and a monitoring device thereof. The change of the oil content of the oily water can cause the change of the viscous resistance correspondingly, and the change of the viscous resistance of the oily water is monitored to calculate the oil content of the oily water. The oily water enters the monitoring device, the blade of the device rotates at high speed, and while the oily water is stirred to be uniform, the change condition of the viscous resistance of the oily water is monitored; the change of the viscous resistance of the oily water can cause the change of the rotating speed of the blade under a condition of constant input power, the change of the rotating speed of the blade is recorded in a pulse form after being amplified by a step-up box, and the change of the pulse number is contrastively analyzed, so that the oil content of the oily water can be calculated. Small change of the viscous resistance of the oily water can be recorded by a pulse counter, so that the monitoring method has sensitive response and high precision, can be used for different oil products and is suitable for a condition of wide fluctuation of the oil content.

Description

technical field

[0001] This patent relates to a method for real-time monitoring of oil content in sewage oil and water and its monitoring device. This method can be applied to various fields that need to monitor oil content, including water cutting in oil tanks, water cutting in electric desalination, and monitoring of oil content in oil well output fluids. , Monitoring of sewage oily water discharge, etc. technical background

[0002] At present, there are many methods for monitoring the oil content in sewage oil and water, such as vibration method, infrared and other ray monitoring methods, ultrasonic method, motor-driven gyro method, motor-driven gossamer torque method and so on. The above-mentioned various methods have their advantages and disadvantages and a certain scope of application, and it is difficult to adapt to changes in light and heavy oil products and large fluctuations in oil content. Therefore, these oil content monitoring methods are subject to certain lim...

Embodiment example

[0026] A method for monitoring the oil content of dirty oil and water by using the relationship between the oil content of dirty oil and water and viscous resistance. The relationship table of resistance, and then compare the detected viscous resistance with the measured relationship table, so as to obtain the oil content of sewage oil and water in real time. The oil-water oil content monitoring device includes: water inlet 11, solenoid valve 12, system protection shell 13 , a monitoring device 14 , a communication module 15 , a water pump 16 , a one-way valve 17 , and a water outlet 18 . The design of this patent is a method of calculating the oil content of the sewage oil and water by monitoring the change of the viscous resistance caused by the change of the oil content of the sewage oil and water. The sewage oil and water enter the monitoring device 14 through the water inlet 11 for monitoring Container 27, the device drives the speed-up box 24 to work through the driving ...
