Title:
GAS AND LIQUID SUPPLY DEVICE
Document Type and Number:
Japanese Patent JP3647731
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a gas and liquid supply device which can increase the solubility of air in water to supply a gas and liquid fluid having a high concentration of dissolved oxygen and can produce fine air bubbles to supply a gas and liquid fluid having an air lift effect by feeding the gas and liquid fluid by a pump, concentrating air to a center by a screw to uniformly supply it to an aperture plate, expanding it rapidly by an expanding pipe to divide it into parts, setting a time for dissolving air in the expanding pipe and a feed pipe, and controlling pressure with a throttle valve to change the solubility of air by the pressure.
SOLUTION: This gas and liquid supply device comprises a suction pipe 1, a discharge pipe 2, an expanding pipe 3, a feed pipe 4, an air intake pipe 5, an intake air control valve 6, a pump 7, an aperture plate 8, a screw 9, a throttle valve 10, and the like, and if necessary, an agitation member is installed in the expanding pipe 3 or the like.
