Embodiment Construction

[0030] The following embodiments are merely examples. Although a specification may refer to "one" embodiment in multiple places, this does not necessarily mean that the same embodiment is referred to each time, or that a feature is only applicable to a single embodiment. Individual features of different embodiments may also be combined to provide other embodiments. Furthermore, the words "comprising" and "comprising" should be understood not to limit the described embodiments to only those features mentioned, but these embodiments may also contain features / structures not specifically mentioned.

[0031] It should be noted that while the several figures illustrate various embodiments, they are simplified diagrams illustrating only some structural and / or functional entities. The operative connections shown in these figures may be logical or physical connections. It will be apparent to those skilled in the art that the described devices may include other functions and structure...

Abstract

An apparatus for measuring suspension comprises an image capturing device (100) for capturing at least one measurement image (200) of the suspension (102), the at least one measurement image presenting at least one solid particle (202); an information processing unit (112) which receives the at least one measurement image (200) and determines a state of attachment of the solid particles (202) of the suspension (102) to each other on the basis of pattern recognition applied to the at least one measurement image (200). The information processing unit (112) determines, on the basis of the state of the attachment of the solid particles (202) of the suspension (102), suspension data associated with at least one of the following: at least one process control chemical, at least one fiber property, at least one fines property, a relation between solid particles of different sizes, formation, and water content.

Description

technical field [0001] The invention relates to a device and a method for measuring suspension and controlling suspension process. Background technique [0002] Quantification of paper machine wet-end chemicals is usually based on conventional wet-end chemistry measurements by charge analyzers, conductivity meters, pH meters, etc. Additionally, the dosage of process control chemicals may depend on measurements made of paper properties and paper machine runnability. The assumed effects of these process control chemicals on the process are based on laboratory studies and theory which, in practice, do not correlate well with the effects in actual industrial production processes. This is why the controller of the paper machine does not actually have information on the state of the process, so the controller cannot determine whether the process is at, near or far from optimum. Lab tests to check system performance are also rarely performed. [0003] Water removal is another cr...
