multi-channel injector

Abstract

The invention relates to a multi-channel jet device and belongs to the technical field of jet pumps utilizing pumped fluid inertia for pumping fluid. The multi-channel jet device comprises a jet box provided with an outlet, a left clamping plate and a right clamping plate which are attached to each other are arranged in the jet box, a jet liquid inlet pipe penetrating through the left clamping plate and perpendicular to the same is arranged at the center of the left clamping plate, an inlet end of the jet liquid inlet pipe is communicated with the outside of the jet box, a plurality of jet nozzles communicated with the jet liquid inlet pipe are made between the left clamping plate and the right clamping plate and are distributed around the jet liquid inlet pipe circumferentially and uniformly, the orifice diameter of each jet nozzle ranges from 8mm to 20mm, an outlet end of each jet nozzle is opposite to the outlet of the jet box, and gas inlet pipes communicated with each jet nozzle are arranged at the edge of the right clamping plate. The multi-channel jet device has the advantages of high bearing pressure and good cleaning performance.

Description

technical field [0001] The invention relates to a negative pressure suction device, which belongs to the technical field of jet pumps for pumping fluid by utilizing the inertia of the pumped fluid. Background technique [0002] Jet vacuum pump is a device that generates, improves and maintains vacuum in a closed space by mechanical, physical, chemical or physical and chemical methods. It is generally composed of three parts: submersible pump, ejector, and pump box. It is widely used in decompression evaporation, crystallization, distillation, drying, decolorization, deodorization, vacuum transportation, etc. in petroleum, chemical, food, pharmaceutical, light industry, environmental protection and other industries.
