Calculation of gas-liquid ejectors
Thread Content
I want to build a gas jet absorber. The flow rate of the existing liquid circulation pump is 1 m3/h; I need to determine the relevant parameters for this jet absorber, such as the nozzle diameter, the diameter of the mixing chamber, and the diameter of the diffusion chamber. Used to absorb gases for cyclic reactions.
This is too general; the parameters are not detailed enough. 1. Liquid ejector: High pressure difference, low pumping volume. 2. Venturi scrubber: low pressure difference, moderate pumping capacity. 3. Liquid jet exhaust fan: low pressure difference, high air extraction capacity. It depends on your operational requirements.
It is a cyclic reaction; both the inlet and outlet are at atmospheric pressure, with little backpressure. The pressure difference is small, so a large amount of gas is drawn in. After mixing with the reaction liquid, the unreacted components overflow out of the liquid, where they are then absorbed and subjected to further reaction.
Do you have any blueprints? Could you provide one for reference?
Similar to exhaust gas absorption devices: a liquid is used to absorb gas; it is necessary for the liquid material to be atomized into droplets of a certain diameter, so as to ensure a sufficient contact area with the gaseous material while also enabling effective mass transfer. That is, 1: ensuring a sufficient contact area to achieve absorption or reaction. 2. Ensure a certain speed so that the gas can be drawn into the equipment, mixed for reaction, and then discharged smoothly. I have previously built the smallest testing unit: DN50x1200mm, with a liquid flow rate of 2 m3/h and an exhaust volume of 100 m3/h.
It involves the direct addition reaction of gas with liquid radicals, with the aim of improving the utilization rate of hydrogen chloride gas through a cyclic reaction, thereby consuming the gas!
Oh, this belongs to the loop reaction injector, a wireless self-circulating system.

With such a small amount of work, using experience values to determine an approximate ratio is sufficient for practical use. For precision, refer to the design calculation methods for injectors; the basic fluid dynamics equation is the Whitehead equation, and the main design parameters can also be derived from this equation.
