Intelligent ship sewage discharge monitoring device

Abstract

The invention discloses an intelligent ship sewage discharge monitoring device. The device comprises a computer control unit, a value control box, a signal acquisition control box, an oil concentration measurement unit and a sewage discharge pipe, wherein the oil concentration measurement unit comprises an oil concentration measurement device, a sampling pump and a sampling head; the sewage discharge pipe comprises a sewage absorption pipe, a branch pipe I and a branch pipe II, and a drain valve and a return valve are arranged in the branch pipe I and the branch pipe II respectively; a sampling pump control box is electrically connected with the sampling pump; the drain valve and the return valve are electrically connected with the valve control box; the sampling pump control box and the valve control box are electrically connected with the signal acquisition control box; the signal acquisition control box is electrically connected with the computer control unit; the oil concentration measurement device adopts an oil concentration sensor adopting a double-wavelength correlative extinction measurement method. The device is further improved and characterized by further comprising a flow meter and a washing unit. The intelligent ship sewage discharge monitoring device can monitor the concentration and the discharge capacity of sewage of various oil products discharged by a ship, and is high in measurement precision and good in stability.

Description

technical field [0001] The invention relates to the field of sewage discharge monitoring, in particular to a monitoring device for overboard discharge of oily sewage from ships. Background technique [0002] Ships need to discharge sewage, and most of the discharged sewage contains oil. In order to control and reduce the pollution of ships to the ocean, sewage discharge monitoring devices are generally installed on ships. An oil concentration measuring device is installed in the existing ship sewage discharge monitoring device to measure the oil concentration of the sewage in the sewage pipe. The defects of the existing ship sewage discharge monitoring device are: first, the monitoring scope is small, and only a single oil type sewage concentration can be monitored; second, the oil concentration measurement results are interfered by other pollutants, and the measurement accuracy is low and the stability is poor. Contents of the invention [0003] Aiming at the deficiencie...
