We have analyzed different modifications of Venturi tubes for gas scrubbing. Preference was given to the modular principle of apparatus construction. We suggested the structure of Venturi modular contact element (VMCE).Interaction between gas and liquid in the VMCE is veryeffective.Thestructure of the VMCE is simple. It consists of a steel confuser with a neck and a plastic diffuser. Two types of VMCE operation are possible: nozzle or film irrigation. It was established, that if the gas velocity in the neck is less than 70 m/s, the pressure loss of VMCE with nozzle irrigation is significantly higher. Thus, ∆p is very sensitive to the irrigation method. It was shown that the VMCE with the film irrigation is more preferable. We studied different modifications of VMCE with the film irrigation. The best structure is VMCE with tangential slots on the confuser. The VMCE gas output vary from 50 to 130 m3/h. The experimental formulas for VMCEwith the film irrigation were received.
