Welding concentrated purifier ordinary air curtain gas collection

Welding and concentrate purifier regular air curtain gas buy welding purifier has two layers inside and outside the gas-collecting hood, blower through gas collecting inside and outside two layer of interlining is placed, the air from the vent, forming a umbrella air curtain, shielding the suction area again under the suction effect of exhaust fan, through the gas-collecting hood center inspiratory mouth will harmful air come in. Welding gas purifier rotating air curtain set buy welding centralization purifier it is in the four corners to install air column, in the Angle of the side within the same direction of rotation to the continuous air curtain, air curtain formed space. Top in the center of the air curtain outlet is equipped with the dust control principle and the ordinary air curtain without turning the gas-collecting hood is different, it besides using air curtain shielding effect, more major is also used throughout the tornado &; Effect. Is in the center of the rotating flow due to breathe in and produce negative pressure, the pressure core is rotating airflow by centrifugal force role; At the same time, the air flow in the heart of the spinning process under the effect of centrifugal force. Within the scope of the centripetal force and centrifugal force balance, rotating airflow vortex formation, eddy current closed outlet in core surrounded by negative pressure, and toward the east. Because of using the principles of tornadoes, full flow core has a bigger rise. Outlet to capture distance of pests. Gas episodic gas-collecting hood has the following main advantages: a. Can use the remote capture dust gas; b。 With a closed space of air curtain, air flow with dust is separated with the outside world, can use lesser exhaust air decontamination air; c。 Has ability to resist horizontal airflow, smaller transverse flow interference.
