Venturi mixing device with position-adjustable injector holes in throat part

Abstract

The invention discloses a Venturi mixing device with position-adjustable injector holes in a throat part. The Venturi mixing device comprises a Venturi tube front section, a Venturi tube rear section,studs, nuts, single-head bolts, flange nuts, an injector hole cushion block, an adjusting cushion block group, a front section injector hole group, a front section bolt through hole group, a front section flange, front section injector holes, front section bolt through holes, a rear section injector hole group, a rear section bolt through hole group, a rear section flange, rear section injector holes, rear section bolt through holes and adjusting cushion blocks; the adjusting cushion block group and the injector hole cushion block are embedded into a cylindrical cavity spliced by the Venturitube front section and the Venturi tube rear section, and after the sections are fixed by the bolts and the nuts, the whole mixing device is formed; the mixing effect of the device can be changed by changing the insertion sequence of the injector hole cushion block in the adjusting cushion block group. The Venturi mixing device is applicable to multiple working conditions, manpower and time cost are saved, complete internal flow field of the device is protected, and elements in the tube are relatively convenient to clean.

Description

technical field [0001] The invention relates to the field of Venturi technology, in particular to a Venturi mixing device with an adjustable throat injection hole. Background technique [0002] Venturi involves many fields, including military, energy, agriculture, materials, chemical industry and many other fields. It can generate local low-pressure areas and has high utilization value. The Venturi mixer uses the mainstream fluid to flow to the throat through the tapered section of the Venturi tube. Throat ejection holes are ejected into the Venturi tube to achieve mixing of the two fluids. [0003] The throat of the Venturi mixing device is provided with injection holes, and the relative position of the injection holes in the throat of the Venturi tube is one of the important factors affecting the device. The actual working process of the Venturi mixing device often involves a variety of mixing ratio conditions, but the current conventional Venturi mixing device cannot ch...

AI Technical Summary

Problems solved by technology

The actual working process of the Venturi mixing device often involves a variety of mixing ratio conditions, but at present, the conventional Venturi mixing device cannot change the relative position of the injection hole in the Venturi tube, so in order to meet the requirements of different mixing ratios, it must Processing multiple mixing devices, high manpower and time costs
