The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The summary that gas mixed liquor generating apparatus is described that sees figures.1.and.2 constitutes.Gas mixed liquor generating apparatus is substantially by liquid storage chamber 2, gas supply device (comprises atmosphere storage device 10, electromagnetic switch valve 9, check valve 8), looping construct (liquid line 13, electromagnetic switch valve 15), Liqiud-gas mixing device 7, gas mixed liquor storage device (electromagnetic switch valve 12, gas mixed liquor storage device 13) constitutes.
In liquid storage chamber 2, can be by the former water of electromagnetic switch valve 1 injection as processed liquid.Liquid storage chamber 2 is used for storing the gas mixed liquor of former water and circulation.The former water of liquid storage chamber 2 under water pump 4 effect, flow through liquid line 3, check valve 5 and liquid line 6, wherein liquid line 6 and Liqiud-gas mixing device 7 sealed attachment.Gas supply device is for being used for the device of generation and ozone supply, and the ozone that is generated by gas supply device supplies to Liqiud-gas mixing device 7 by check valve 8 and the electromagnetic switch valve of being located in the gas supply pipe 9.Water fully mixes in Liqiud-gas mixing device 7 inside with ozone, flow out via follow-up pipeline then, be connected with gas concentration of ordinary dissolution checkout gear 11 at pipeline, if the ozone concentration of ordinary dissolution reaches requirement, then open electromagnetic switch valve 12, the gas mixed liquor enters gas mixed liquor storage device 13; If the ozone concentration of ordinary dissolution does not reach requirement, then electromagnetic switch valve 12 is closed, and electromagnetic switch 15 is opened, and the gas mixed liquor reenters in the liquid storage chamber 2 by looping construct, mixes with ozone again, till the ozone concentration of ordinary dissolution reaches requirement.
Describe Liqiud-gas mixing device 7 in detail below with reference to Fig. 2, Fig. 3 and Fig. 4.Liqiud-gas mixing device 7 is by first mixing chamber 16, gas adapter 17, the second mixing chambers 18, and liquid adapter 19, gas atomization module 26, gas-liquid atomizing module 20, rotating vane 21 and helical member 22 are formed.First mixing chamber 16 is connected with the extraneous gas seal for pipe joints by gas adapter 17, wherein is placed with gas atomization module 26, circlip 25, steel ball 24, spring 23 in the gas adapter.Circlip 25, steel ball 24 and spring 23 are formed simple and easy check valve, prevent that liquid from entering gas piping from first mixing chamber 16.
Gas at first enters gas atomization module 26 by gas adapter 17, and focused airflow is dispersed into the tiny air-flow in a lot of roads.Liquid enters into first mixing chamber 16 under the effect of water pump 4, because Venturi effect, form jet at first mixing chamber, 16 front end bellmouths, cause parital vacuum, thereby (the gas atomization module can be by being made of the multi-layer gas screen pack to suck the refinement gas that disperses through gas atomization module 26, but be not the impurity in the filtering gas, but utilize the pore on the filter screen to disperse and refinement gas, the position of flowing through earlier with gas is the front portion, the gas filtration net is from the front portion to the rear portion, and width of mesh is descending; To close, liquid mixes with the gas of refinement is easier density by rare, improves Gas Solubility.Exist considerable than air pocket, very unstable in the first gas-liquid mixture that forms.
With reference to Fig. 3 and Fig. 5, first mixing chamber 16 and second mixing chamber, 18 sealed attachment, between isolate by division board 27, division board 27 has pod apertures 28.Rotating shaft 29 passes second mixing chamber 18, is tightly connected with it, and rotating shaft 29 front ends are equipped with self-priming rotating vane 21, on rotating shaft 29 main shafts helical member 22 is installed.It is characterized in that rotating shaft 29 rotates under external force drives and since the effect of self-priming rotating vane 21 hybrid with first in the first gas-liquid mixture that merges suck second mixing chamber 18, middlely enter second mixing chamber 18 by the pod apertures 28 on the division board 27.28 pairs of mixtures of pod apertures carry out the first time and decompose, mixture is split into multichannel, and form many places parital vacuum and the bigger bubble that breaks in advance, and reduce the flow through fluid resistance of gas-liquid atomizing module 20 of gas-liquid mixture, avoid gas-liquid atomizing module 20 that gross distortion or destructions are taken place.20 pairs of gas mixed liquors of gas-liquid atomizing module carry out the second time and decompose, with the further refinement of gas-liquid mixture of decomposing for the first time, when the gas that is dissolved in the water passes through gas-liquid atomizing module 20, bubble break the force of explosion that produces will around bubble and current disperse, the bubble chain reaction of breaking forms refining effect preferably to gas and liquid.Under the effect of rotating vane 21, form the self-priming effect, under the effect of helical member 22, form spiral channel, form good turbulent pressurized effect by self-priming rotating vane 21 and helical member 22, the gas after the refinement and liquid are carried out secondary fully mix.
Pod apertures 28 on the division board 27 according to the flow direction of shunting back gas-liquid mixture, needs that parital vacuum point designs and to the active force of gas-liquid atomizing module 20, can design the pod apertures of varying number and shape.
The utility model can be used for Medical Devices, in ozone flushing therapy apparatus, also can be applicable in the home disinfecting equipment.The utility model can make ozone mix efficiently with water, makes the ozone solubility in the water can satisfy the requirement of sterilizing, and uses safety, efficient height.
