Various adsorption characteristics of pipe type electrostatic precipitator

When the pipe electrostatic precipitator is started, the internal motor rotates to form a wind, which sucks in the dust from the outside. At the same time, in order to hold more dust, the parts inside have a certain adsorption function. Under normal circumstances, low temperature operation is conducive to physical adsorption, and the appropriate increase of temperature is conducive to chemisorption. However, heating or cooling should be based on the adsorption process in the adsorption process. If the burr becomes positive, the temperature rise is beneficial to the adsorption operation. For gas adsorption, pressure increase is conducive to adsorption, and pressure reduction is conducive to desorption.


The smaller the particle size of the adsorbent or the more developed the micropore, the larger the specific surface area and the larger the adsorption capacity. If the same kind of activated carbon is used as adsorbent, the greater the relative molecular weight and unsaturation, the higher the boiling point, the easier the adsorption. For liquid phase adsorption, the molecular polarity, relative molecular mass and solubility of the adsorbate affect the adsorption capacity. The larger the molecular weight, the stronger the polarity of the molecule, the smaller the solubility, the easier it is to be adsorbed. The higher the adsorbate concentration, the less adsorption capacity.


In order to keep the adsorption close to equilibrium, it is necessary to ensure that the adsorbate and the adsorbent have a certain contact time and make full use of the adsorbent's adsorption capacity. It is necessary to determine the best contact time through economic trade-off, so that the pipe electrostatic precipitator can obtain the best dust removal effect.
