Abstract

The invention provides a device and method for measuring parameters of non-spherical particles under the gas-solid flow condition. Accelerated speed, rotational acceleration, spatial attitude, impact stress and the rate of heat flow are measured through a micro attitude sensor, a temperature sensor and a stress sensor, and are sent to the outside through an NFC near-field communication method, the micro attitude sensor, the temperature sensor and the stress sensor are arranged in an intelligent tracing particle, and the needed kinetic and heat transfer parameters are obtained after the accelerated speed, the rotational acceleration, the spatial attitude, the impact stress and the rate of heat flow are processed. According to the scheme, the kinetic and heat transfer parameters of the non-spherical particles can be measured accurately and safely in real time under the condition of not interfering with a flow field.

Description

technical field [0001] The invention relates to a device and method for measuring parameters of non-spherical particles under the condition of dense gas-solid flow, and belongs to the technical field of multiphase flow measurement. Background technique [0002] In the field of modern energy and environmental protection, it is often necessary to process biomass or waste particles in dense gas-solid flow equipment such as fluidized beds by means of combustion and pyrolysis. These particles are often large in size and irregular in shape. Their gas-solid flow process in fluidized beds and other equipment is extremely complicated, and the law of movement is difficult to grasp. Equipment lacks reliable theoretical guidance and numerical simulation in terms of design amplification and operation optimization, and can only rely on experience, and its safe operation and processing efficiency are difficult to guarantee. Therefore, the academic and theoretical circles urgently need adv...
