The skeleton Venturi tube produced by Hebei Huada Environmental Protection Dust Removal Company is the abbreviation of Venturi tube, which is a type of dust removal accessory. The principle of Venturi effect is that when wind blows over a barrier, the air pressure near the port on the leeward side of the barrier is relatively low, resulting in adsorption and air flow. The principle of a Venturi tube is actually very simple. It changes the airflow from coarse to fine to accelerate the gas flow rate, creating a "vacuum" zone behind the exit of the Venturi tube.

The main function of the Venturi tube is to induce secondary airflow. When cleaning the filter bag, secondary air that is 5-8 times larger than the compressed air injected is induced to enter the filter bag when the high-speed airflow passes through the Venturi tube, causing the filter bag to rapidly expand instantly. Due to the reverse effect of the airflow, the dust accumulated on the filter bag falls off.

It can use airflow to transport powder materials. When cleaning the filter bag, secondary air that is 5-8 times larger than the compressed air injected is induced to enter the filter bag when the high-speed airflow passes through the Venturi tube, causing the filter bag to rapidly expand instantly. Due to the reverse effect of the airflow, the dust accumulated on the filter bag falls off. The Venturi tube greatly improves the intensity and effectiveness of pulse blowing, reduces the amount of compressed air used, and saves energy.
