Description

Multi-suction reinforced mixing Venturi reactor
Technical Field
The invention relates to a multi-suction reinforced mixing Venturi reactor which strengthens the chemical reaction speed and improves the utilization rate of chemical medicines.
Background
The rate at which chemical reactions occur with a variety of fluids is affected by a variety of factors such as the intensity of mass transfer, the contact area, the form of the reaction, etc. When the gas-liquid reaction is involved, a bubbling reactor, a washing tower or a spraying tower type reactor is often used, and the reactor has the problems of poor gas-liquid reaction effect and low chemical agent utilization rate. The invention is designed and modified into a multi-suction channel based on the traditional Venturi ejector, so that various reaction fluids are mixed in high-speed, negative-pressure and strong-disturbance environments, thereby strengthening mass transfer, increasing contact area and improving reaction rate. Meanwhile, the ejector can trigger cavitation effect under certain working condition to generate hydroxyl free radical, micro-jet and other phenomena, thereby further promoting the occurrence of chemical reaction.
The current gas-liquid two-phase reaction is mainly limited by the contact area, and the size of the reactor needs to be designed to be large in order to improve the contact area. The hydrodynamic cavitation reactor formed by the venturi tube with multiple suction inlets can realize a large liquid-gas ratio on a small-sized reactor, greatly promote gas-liquid mixing, improve the utilization rate of reaction medicines and improve the chemical reaction rate.
Disclosure of Invention
According to the technical problem, a multi-suction enhanced mixing venturi reactor is provided. The invention adopts the following technical means:
a multi-suction enhanced mixing Venturi reactor comprises a Venturi tube convergent section, a Venturi tube throat section and a Venturi tube diffusion section which are connected in sequence;
Two or more suction pipelines are uniformly arranged on the negative pressure section of the throat part of the venturi tube along the axis of the multi-suction enhanced mixing venturi reactor, namely, the two or more suction pipelines are respectively positioned at different positions of the negative pressure section of the throat part of the venturi tube.
Liquid enters through the free end of the converging section of the venturi tube, and a negative pressure section is formed at the throat part of the venturi tube, so that the fluid is sucked in a sectional mode.
The multi-suction enhanced mixing venturi reactor is a mixing suction venturi jet device designed by utilizing a jet negative pressure cavitation principle, can increase the types and modes of sucked fluids, drives the fluids to suck two or more fluids simultaneously and uniformly mix the two or more fluids, and allows different fluids to enter from different suction pipelines, so that the contact area is increased, the mass transfer is enhanced, and the reaction speed and the medicine utilization rate are increased.
The axis of the suction pipeline is perpendicular to the axis of the multi-suction enhanced mixing Venturi reactor;
the orthographic projection of the suction pipeline in a plane perpendicular to the axis of the multi-suction enhanced mixing Venturi reactor is uniformly distributed by taking the axis of the multi-suction enhanced mixing Venturi reactor as an axis.
The suction pipeline is communicated with the venturi throat through an annular cavity protruding outwards from the outer wall of the venturi throat, and an inner ring of the annular cavity is communicated with the venturi throat.
The fluid enters the annular cavity to form annular mixed liquid, so that the utilization rate of medicines is improved, and the dosage is reduced.
One part of the suction pipeline is used for absorbing the reaction fluid, and the other part of the suction pipeline is used for absorbing the fluid to be treated.
Compared with the prior art, the invention has the following beneficial effects:
The invention strengthens the mixing mode of the reaction fluid, strengthens the mixing and mass transfer disturbance of the fluid in the venturi tube, reduces the dosage and improves the chemical reaction rate by arranging two or more suction pipelines at the negative pressure section of the throat part of the venturi tube.
