Various filter works and the advantages and disadvantages: gravity settling chamber: by gravity to separate dust particles from the air stream Hangzhou ventilation pipe processing, after the dust stream entering gravity settling chamber, the flow rate of the rapid decline in Hangzhou processing ventilation pipe, the layer state or close to laminar flow motion under workshop ventilation pipe, which the hopper dust slowly settling under gravity. Applicable diameter> 50μm. Adsorption: let ventilation and some solid materials in contact with, the use of the solid material to remove gas adsorption process of certain hazardous substances. Uniform air: According to requirements of industrial and civil buildings, ventilation and air conditioning duct system may need to be the same amount of air, along the side wall of the duct opening or short tube rows evenly sent. This approach is called a uniform air blast. Hangzhou ventilation pipe processing (FIG), angle iron ventilation pipes, ventilation ducts Lin'an supplied by Hangzhou Xingda ventilation equipment.
