System for automatically monitoring and controlling mechanical agitating fuel oil and water mixing device

Abstract

The invention relates to a system for automatically monitoring and controlling a mechanical agitating fuel oil and water mixing device, comprising the steps of: adding clean water and fuel oil into a water mixing device respectively through a water metering pump and a fuel oil metering pump at the same time, and mechanically agitating the clean water and the fuel oil to generate water mixed fuel oil, putting the water mixed fuel oil into a water mixed fuel oil tank, delivering the water mixed fuel oil to boiler through a water mixed fuel oil delivery pump and burning the water mixed fuel oil in a boiler, wherein by utilizing a PLC (Programmable Logic Controller), combustion characteristic of the water mixed fuel oil can be optimized according to the characteristic of the fuel oil used on spot and the spot environment through changing the mixing ratio of the water and the fuel oil in the water mixed fuel oil and regulating the frequency of agitator motor frequency converter of a water mixing device; the supply quantity of the water mixed fuel oil delivered to the boiler can be regulated according to steam quality of the boiler; the water inlet quantity can be regulated according to a water flowmeter and the oil inlet quantity can be regulated according to a fuel oil flowmeter; and the generation quantity of the water mixed fuel oil can be regulated according to liquid level of the water mixed fuel oil tank. By utilizing the system, a real-time automatic control on the fuel oil and water mixing technical process can be realized and the mechanical agitating fuel oil and water mixing device can operate safely and reliably and can reach the standard in operation.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to an automatic monitoring and control system of a mechanical stirring fuel water mixing device. Background technique [0002] Fuel water mixing technology is an energy-saving technology, which is widely used because of its high efficiency and energy saving, reducing pollution, and reducing the content of sulfur, nitrogen oxides and soot in flue gas. [0003] The technical principle of the mechanical stirring fuel water mixing device is: without adding emulsifier, quantitative water mixing and special mechanical stirring are used to form water mixed fuel oil, and a "micro-explosion" effect occurs during the spray combustion process in the burner, so as to save fuel and reduce fuel consumption. Arrangement and synergy effect. [0004] The core unit of the mechanical stirring fuel water mixing device is the emulsifier, which is the core component of mechanical stirring. Through the a...
