Introduction to the Basic Performance of Wet Dust Collector
Wet dust collector is a typeCapture dust through the contact of liquid (usually water) with dusty airflow, utilizing inertial collision, interception, diffusion, and other effectsThe purification equipment has the functions of dust removal, cooling, and absorption of some harmful gases, and is widely used in dust producing industries such as mining, metallurgy, chemical engineering, and mechanical processing.
After entering the dust collector, the dusty gas comes into full contact with atomized droplets, liquid films, or bubbles. Dust particles will adhere to the liquid medium, forming dusty droplets or mud. Subsequently, gas-liquid separation is achieved through gravity settling, centrifugal separation, and other methods. The purified gas is discharged, and the dusty mud is collected and processed.
advantage
High dust removal efficiency: YesHydrophilic dustFine dust (such as dust with a particle size less than 10 μ m) has a good capture effect, and some types (such as Venturi wet dust collectors) can achieve a removal efficiency of over 95% for fine dust.
Combining multiple functionsIn addition to dust removal, it can also reduce gas temperature and absorb some harmful components in the gas (such as SO ₂, HCl, etc.), suitable for high temperature and dust removal scenarios containing harmful gases.
The device structure is relatively simpleLow cost and initial investment, easy maintenance and operation, and less likely to generate secondary dust.
Good safetyDue to the use of liquid as the medium, it can effectively prevent dust explosions and is suitable for handling flammable and explosive dust (such as aluminum powder and coal powder).
shortcoming
Generate dusty wastewater/mudSupporting sewage treatment or mud drying equipment is required, otherwise it may cause secondary pollution and increase the cost of subsequent treatment.
Poor treatment effect on hydrophobic dustIf wetting agents are not added, the capture efficiency of hydrophobic dust such as paraffin, graphite, and carbon black will significantly decrease.
There is a risk of corrosion and antifreezeThe inner wall of the equipment is prone to corrosion due to long-term contact with water; In low-temperature environments, liquids may freeze, affecting equipment operation.
Not suitable for dust that is sensitive to moistureUnable to handle dust that is prone to clumping and deterioration when in contact with water (such as cement clinker dust).
