Measuring method and measuring device for measuring charge quantity of charged particles in collection tank of electrostatic separator

Abstract

The invention discloses a measuring method for measuring the charge quantity of charged particles in a collection tank of an electrostatic separator and a related device. According to the method, first, charged particles are connected into a special charged particle collection assembly, then, the sensing voltage U of each collection unit is measured, and finally, the charge quantity of the charged particles (Q=C*U) is calculated based on the sensing voltage U of each collection unit and the capacitance C of each collection unit. The device comprises a charged particle collection assembly and a data acquisition analyzer. The charged particle collection assembly is composed of collection units. Each collection unit is composed of an inner conductive channel and an outer conductive channel. The axial sides of the outer conductive channels of adjacent collection units are connected by an adhesive tape and insulated from each other, and a triangular splitter is pasted on the adhesive tape. The collection units are connected with the data acquisition analyzer through wires. The measuring method and the device of the invention are economical and practical, simple to operate, easy to implement, and accurate in measurement. The problem that the charge quantity of charged particles falling into the collection tank of an electrostatic separator cannot be measured is solved.

Description

technical field [0001] The invention relates to a research device and method related to an electrostatic separator, in particular to a method and a measuring device for measuring the amount of charge of charged particles in a collection tank of an electrostatic separator. Background technique [0002] With the rapid development of the electronic information industry, the disposal of more and more electronic waste has become a new topic facing the sustainable development of economy, society and environment and the recycling of renewable resources. Since the grade of metals in electronic products is equivalent to dozens or even hundreds of times that of ordinary minerals, the technical requirements for decomposition and recovery are high, and these electronic products cannot be disposed of by traditional methods (such as landfill and incineration), so electrostatic separation method It has been applied in the field of electronic waste recycling. High-voltage electrostatic sep...
