METHOD AND APPARATUS FOR IMPREGNATING A LIQUID WITH A GAS AND MORE SPECIFICALLY, FOR IMPREGNATING IRRIGATION WATER WITH CO.SUB.2 FOR HORTICULTURAL BUSINESSES, HOBBY GARDENERS OR THE LIKE

摘要

Abstract of the InventionMethods and apparatuses for the fine impregnation of aliquid with a gas are provided. An injector system serves thispurpose - with the aid of said injector system a liquid streamis advanced through cross-sections of flow which successivelyincrease in a step-like manner and thus flow rate of the liquidstream abruptly decreases step-by-step. Where the flow rateabruptly changes the liquid is brought into direct contactwith the gas. The gas is absorbed by the liquid in the formof bubbles the finest possible and is blended over the entirecross-section of flow. Fine impregnation of the liquid is stillfurthered by the reconversion of the liquid while flowingthrough the apparatus. All parts required can be provided inan apparatus block. A simple, normal water supply system thatcan be turned off by means of a faucet can be connected tothe apparatus block so that the water acts on a diaphragmthrough the respective water pressure when the water flows into,said diaphragm controls the shut-off valve of a commoncompressed gas container connected to the apparatus block -such as a C02 - compressed gas cylinder -. Dosed amounts offertilizer can be automatically added to the water fineimpregnated with C02, if desired, with the aid of variouspressures present at various points in the apparatus block.Entire control of the apparatus can be exclusively turned onand off by merely turning the faucet in the water supply systemon and off.
