Abstract
The invention provides a thickness detection device and method based on a semi-cylindrical shell capacitor. The thickness detection device comprises the semi-cylindrical shell capacitor, a base, a sensor and a controller, wherein the semi-cylindrical shell capacitor comprises an outer polar plate and an inner polar plate; the outer polar plate and the inner polar plate both comprise an upper compensation polar plate, a middle working polar plate and a lower compensation polar plate in sequence from top to bottom; the base comprises an outer ring and an inner ring that are nested, the upper part of the inner ring is connected to the lower compensation polar plate of the inner polar plate, the inner ring is connected to a driving device, and the upper part of the outer ring is connected to the lower compensation polar plate of the outer polar plate; and the controller is connected to the upper compensation polar plate, the middle working polar plate, the lower compensation polar plate, the sensor and the driving device, respectively. The invention can adapt to the variable environment of an industrial chimney, can accurately, quickly and effectively detect the thickness of dust deposition by adopting a double-compensation processing method of the upper and lower polar plates, and is suitable for the detection of the thickness of particles and liquid.
