Description
Technical Field
The invention relates to the fields of powder particle separation, fine dust particle detection, industrial dust removal and the like, in particular to a fine particle automatic detection and intelligent identification device and method for industrial dust removal.
Background
Along with the continuous deepening of understanding of dust pollution and harm, the treatment standard of dust pollution and treatment in various countries is also improved. Therefore, there is a new demand for a dust pollution detection technique. The current dust pollution detection is mainly divided into two aspects, one is directed to the concentration detection of dust particles, and the other is directed to the particle size detection of the dust particles. The particle size detection method mainly comprises detection technologies such as a screening method, an ultrasonic method, a microscope method, a sedimentation method, an electric induction method, a dynamic image method and the like. The measurement technology gradually develops towards networking, automation and wireless control. The control, the investigation and the feedback can be realized at any time and any place. Greatly improving the analysis speed and the detection efficiency.
The screening method is that a vibrating machine is used to screen dust particles through molecular sieves with different pore sizes, the dust particles are screened and selected in multiple stages, then the dust particles on each stage of molecular sieve are respectively weighed, and the average particle size of each stage of the dust particles is calculated through a mass formula. The application range of the dust particle detection by adopting the screening method only aims at the dust particles with the particle size of more than 40 mu m, the operation is complex, the result obtaining time is long, and the method cannot be applied to places requiring timeliness and timeliness.
The microscopic method is to take a sample through a glass slide, take a sample in the direction perpendicular to the dust-carrying airflow direction, and observe the particle distribution conditions of different particle sizes under a high power microscope. But the measurement of the size of the particle size is less responsive.
The ultrasonic method is that dust particles with different particle sizes have different reflection angles, absorption frequencies and attenuation frequencies for sound waves, the dust particles collide and reflect with the dust particles through sound wave interference, the reflected sound waves enter a detection connector, and the particle sizes of the dust particles are indirectly measured through measuring sound wave parameters such as wave troughs, wave crests, sound wave spatial distribution, attenuation rates and the like. The equipment used by the ultrasonic method is usually expensive, and the measurement precision is higher when the dust concentration is lower, but the ultrasonic method is not suitable for the working environment with higher dust concentration.
Sedimentation method is a method for indirectly measuring the particle size of particles by using the sedimentation time of the particles with different particle sizes in an infiltration liquid. The dust particles are settled in the infiltration liquid to form turbid liquid or suspension, and the relation of the particle size of the dust particles is indirectly obtained by measuring the transmittance, the density and other physical parameters of the dust particles under different settling times. The method has higher requirements for the immersion liquid in order to achieve settling of smaller particles. Meanwhile, the operation is complicated, the detection precision is low, and the influence of the environment is large.
The electric induction method is characterized in that in the flowing process of dust-carrying gas, particles are charged due to collision among the particles, collision between the particles and a wall surface, friction, induction charge and the like, and the charge quantity of dust particles with different particle sizes is different. And an induction metal probe is inserted into the detection channel, self-body charges in the dust-carrying airflow cause induction charges of the metal probe, and an electric wave change diagram is obtained through an amplifying circuit with sensitivity, high precision and high amplification factor and through methods such as filtering. The instantaneous average particle size in the pipeline can be calculated through the change of electric waves. The method can only achieve average particle size, and cannot obtain specific particle size distribution. And the anti-interference capability is poor, and the requirement on the precision of the induction circuit is higher. And therefore is only suitable for simpler particle size measurement.
