Welding of concentrated purifier classification concentrated purifier meet with circular and rectangular cross section shape points two kinds.
Answer the throat structure points have no adjusting device of the sizing throat venturi tube, a laryngeal equipped with adjusting device of adjustable venturi tube.
Adjustable venturi tube, to strictly guarantee the purification efficiency, changing with the gas flow regulating throat diameter are needed to keep the throat airflow rate, need to keep changing with the gas flow regulating throat diameter pipes, gas velocity is constant.
Throat diameter regulating mode, circular venturi general use type adjustment;
Rectangular venturi tube can be used to plate, the slider type and grain type adjustment.
Water atomization method points have not spray atomization and two kinds of ways.
Joint water supply way points in spray within the radial, axial and radial outside spray, spray and four types of overflow water supply.
All kinds of water supply way is to facilitate the atomization of water and make the droplets is full whole throat section for the principle.
According to the using time more than single stage venturi tube and GuanWen's sake, etc.
According to the venturi tube and dehydration device supporting device and can be divided into several types.
Welding and concentrate purifier device welding purifier water spray, spray and overflow outside using three forms.
The overflow water is often used with spray or outside spray, has also used individually.
Spray venturi nozzle circular jet venturi tube using needle type nozzle radiating uniform layout.
Nozzle Angle is commonly 15 & deg;
~ 25度;
, there is also value to zero, namely the nozzle on the shrinkage tube near the throat side vertical arrangement and the center line of the venturi tube.
The value, the greater the water atomization, the better, but also the greater the resistance.
For throat venturi tube, water should be paid attention to by the high-speed airflow impact can still injection to the throat center, constitute a closed water curtain.
When necessary, the nozzle can be divided into two layers of staggered arrangement.
In spray venturi nozzle jet venturi tube inside the bowl shape of nozzle, the nozzle of the jet Angle, about 60 & deg;
。
