Venturi is the abbreviation of Venturi tube. The principle of Venturi effect is that when the wind blows through the barrier, the air pressure near the port above the leeward surface of the barrier is relatively low, resulting in adsorption and air flow.
Product classification of Venturi:
1. Divided into single-stage Venturi tube and multi-stage Venturi tube according to the use situation.
2. According to the shape of the section, there are two types: circular and rectangular.
3. According to the supporting device of Venturi tube and dewatering device, Venturi tube dust collector can be divided into several types.
4. According to water atomization methods, there are two types of pre-atomization and non-pre-atomization.
The principle of the Venturi tube is actually very simple. It is to reduce the airflow from coarse to thin to speed up the gas flow rate, so that the gas forms a "vacuum" zone on the back side of the venturi tube. It can realize the conveying of powder by air flow. The Venturi tube mainly uses its ejection and suction effect, and it is widely used, such as in dust collectors, powder conveyers, coolers, flow meters, dryers, etc.
