Non-contact particle size analyzer and application method thereof

Abstract

The invention discloses a non-contact particle size analyzer and an application method thereof, the non-contact particle size analyzer comprises a purging device, a signal acquisition device, a data analysis processing unit and an electrical connection unit, the signal acquisition device comprises a sensor and a radiator, the purging device is connected to the sensor, and the data analysis processing unit is connected to the radiator. The sensor is connected with the data analysis processing unit, the data analysis processing unit is connected with the electrical connection unit, and the electrical connection unit is connected with the power cable and the signal output cable. Based on a particulate matter electrostatic induction measurement core technology of a fluid / statistical model and digital signal processing, the system has an ultra-wide dynamic range and ultra-strong anti-interference capability; under the condition that the measurement requirement is met, any part of the sensor does not need to extend into the valve, and online installation and online maintenance can be realized; the non-contact measurement is realized, the sensitivity and the safety are ultrahigh, and the process is not influenced under the condition that the measurement accuracy is ensured; the adaptability is high.

Description

technical field [0001] The invention relates to a particle size analyzer, in particular to a non-contact particle size analyzer and an application method thereof. Background technique [0002] The sensor of the non-contact particle size analyzer is a non-contact sensing device. It only needs to install the sensor on the online flange of the measured pipeline without inserting the flue. The depth is no more than the position of the valve plate of the gate valve, but not limited to this size), and an analytical instrument that can monitor the particle concentration and particle size in the pipeline. It is mainly used in chemical industry, iron and steel industry, coal industry, petrochemical industry, which is not easy to maintain or requires particle size measurement. For example, when the particle size analyzer fails, the equipment cannot be maintained under working conditions that cannot be shut down, or the relatively harsh working conditions such as high pressure, high t...

AI Technical Summary

Problems solved by technology

[0007] At present, the existing technology for measuring particle concentration and particle size is the laser penetrating principle measurement method. The defects of the instrument of this principle are: 1. Since the light needs to be aimed, the flue in the use occasion should not have a large vibration, otherwise the light will 2. When light encounters particles in the direction of propagation, it will be scattered in all directions. In a specific direction, the intensity of light is related to the concentration of particles. The mechanism is complex and greatly affected by the measurement conditions; 3. Meter measurement It is relatively affected by water vapor, because the equipment is installed on the flange surface outside the valve at the root of the pipeline. If the lens of the instrument is affected by condensed water vapor, serious jumps will occur, and most of them will affect the measurement results; 4. Pollutants Attaching to the lens will block the light and affect the measurement, so regular maintenance is required, and the maintenance workload is relatively large; 5. The lens is polluted by particles for a long time, and the light source and photosensitive element drift seriously
