Wireless-sensing photoelectric-type automatic separation device for oil-water discharge

Abstract

The invention relates to a wireless-sensing photoelectric-type automatic separation device for oil-water discharge. The wireless-sensing photoelectric-type automatic separation device comprises a separation valve used for oil-water discharge, at least one group of photoelectric sensors, a signal processing and operating module and a valve opening-closing controller, wherein the separation valve is installed at the outlet of an oil storage tank or at the outlets of other oil-water discharge devices; the photoelectric sensors are installed at the inlet end of the separation valve; the photoelectric sensor comprises an infrared light source and a photoelectric detection apparatus for receiving the infrared ray emitted by the infrared light source; the photoelectric detection apparatus transmits an output signal to the signal processing and operating module; the signal processing and operating module processes and operates the signal and then sends a control command to the valve; the valve can be automatically opened and closed according to a set threshold; and a wireless module realizes monitoring on the oil storage amount according to the opening time and the closing time of the valve. The automatic separation device has the advantages of being simple in structure, high in accuracy, and low in cost.

Description

technical field [0001] The invention relates to an automatic oil-water discharge separation device for a storage tank, which belongs to a wireless sensor photoelectric oil-water discharge separation device. Background technique [0002] In some industries, especially petrochemical enterprises, it is often necessary to use some methods to effectively drain oil or remove water from oil products. This device is called an oil-water separator. After the oil containing water enters the oil-water separator, due to the different densities of oil and water, after settling, the water falls to the lower part, while the oil is in the upper part, forming an oil-water interface. The production process requires timely and accurate determination of whether the oil-water interface has reached the high level limited by the process. When this high level is reached, the valve should be opened to drain water in time. When the oil-water interface reaches the low level limited by the process, the ...

Problems solved by technology

In fact, the above assumptions are idealized. There is not only an oil-water transition zone in the oil tank, but sometimes the oil-water transition zone is very long. Although the above method determines the oil-water interface, the percentage of oil and water in the oil-water transition zone cannot be determined, so it is impossible to accurately calculate the real amount of oil and water in the tank
