Welding smoke and dust collector dust removal principle

Welding smoke and dust collector dust removal principle of welding dust collector is a horizontal type dust removal equipment. Its features are: high dust removal efficiency, small resistance loss, less water consumption and easy operation, maintenance, etc. , but there are unstable, difficult to control dust removal efficiency suitable water level and so on. Welding smoke and dust collector with transverse cylindrical shell and the inner core, cross-sectional obovoid or inverted pear-shaped. Spiral deflector between shell and the inner core. Dust gas by end along the tangent direction into the dust catcher, and outer 売, between the inner core spiral flow along the spiral flow deflector do to go forward, finally from the other end. Whenever dust flow through a coil suitable surface, as the water flow direction to the outer wall 売, allow the coil to form water membrane. When the dust air flow through the coil, filter each coil will form a continuous water film. Welding dust removal principle of dust collector, dust airflow spiraling into dust catcher, borrow the effect of centrifugal force makes the displacement to the shell of dust particle removal by water film. Airflow every time they hit the water also has the effect that cleaning dust, and fine dust in air many times god struck the water and the water spray, spray suction trap, condensation, accelerate to filter shell displacement, also removed by water film, thus has higher dust removal efficiency. After the dust sampling on the membrane filter dust particles showed that very little dust particle diameter in more than 5 m, mostly 3 m below. As for the water film shape, according to the experiment observation, rising water film side element, such as boiling gruel, and falling water film side is relatively smooth. When a certain speed of dust airflow when leaving suitable each circle of the water with a lot of water spray, spray, according to the different weight of it successively by centrifugal force to 売 outside wall of the water film. Cross-sectional should comply with the principle of dust control requirements, that is, under the lower resistance loss, make each coil to form a complete water film; Cause more after the flow of the water spray, spray, quickly, water mixture, the more intense, more uniform; Additional air flow in the spiral passage, produce larger centrifugal force, in order to obtain higher dust removal efficiency.
