Description

Microvesicle generators
Technical field
The utility model relates to the water treatment field as industries such as sewage disposal, water aquaculture, agricultural irrigation, beauty treatments, is specifically related to a kind of microvesicle generators.
Background technology
In the past, micro-bubble is mainly for separating of the solids aspect in water.And some research departments research in nearest more than 10 years is found, micro-bubble also has prior performance.General bubble breaks can rise to rapidly the water surface in water after at once, and self-annihilate (dissolving) in the way of diameter micro-bubble climbed in water that to be 50 μ m following, when micro-bubble during in self-annihilate moment produce the energy of several thousand degree, produce simultaneously free radical, and stay minimum nano bubble below 1 μ m in water.Therefore the free radical that occurs can be used in the fields such as water treatment because have the performance of good chemical decomposition material.And nano bubble can be used in the fields such as medical treatment, food, biology.For nano bubble resides in water for a long time, need in containing a certain amount of electrolytical water, microvesicle occur, microvesicle is freely swum or apply simple physical stimulation, minimum bubble is steady in a long-term to be retained in order to make.
At present, the method for generation microvesicle has following several; A. micropore generation microvesicle: the lower clogging that easily produces of long-term operation needs to increase maintenance; B. air pocket generation microvesicle: the efficient that microvesicle occurs is not high, uses restricted; C. fluid rotary generation microvesicle: simple in structure, one of microvesicle method for generation of present Japanese application; D. microvesicle occurs in unsteady flow speed: simple in structure, microvesicle easily occurs; E. dissolved under pressure type generation microvesicle: formed by dissolved under pressure tank, high-pressure pump, water outlet nozzle etc.Existing unsteady flow speed microvesicle generators complex structure, manufacturing cost is high, and fault rate is higher and operation maintenance is inconvenient, has greatly improved user's use cost.
The utility model content
The purpose of utility model: for addressing the above problem, the utility model provides a kind of simple in structure, easy to operate microvesicle generators.
Technical scheme: for achieving the above object, the utility model adopts following technical scheme:
A kind of microvesicle generators, comprise fluid inlet section, intake section, air chamber, gas-liquid mixed section, pore section and fluid issuing section, described microvesicle generators center from left to right is sequentially with the fluid inlet section that is connected, gas-liquid mixed section and fluid issuing section successively, be provided with intake section outside described fluid inlet section, intake section communicates with the air chamber that is arranged on along the outer casing inner wall surrounding, and air chamber is connected with fluid inlet section by pore section.
Described fluid inlet section is cone, and the diameter of front end is greater than the diameter of rear end.
Described gas-liquid mixed section is cylinder.
Described fluid issuing section is cone, and the diameter of front end is less than the diameter of rear end.
Described pore section is centripetal along being evenly distributed on the air chamber bottom week, and hole diameter is 0.5-1mm.
Described intake section is centered close to the front end of fluid inlet section or the optional position between rear end or front and back end.
Beneficial effect: the utility model can be applicable to water treatment field, and as industries such as sewage disposal, water aquaculture, agricultural irrigation, medical treatment, food, biology, beauty treatments, application is wide.The utility model adopts the Venturi effect structure, and (as comparing more simple with fluid rotary generation microbubble structure) simple in structure, and can make as required the structure that differs in size, cost is low, is easy to make.When being used in sewage disposal device as the utility model, replace traditional aerating system as oxygen supply equipment, can greatly reduce plant capacity, improve efficiency of oxygen supply; Can either be to small solids absorption floating be separated, can also decomposition water in chemical substance, increased chemical substance function solids absorption floating, decomposition water from original single oxygen supply function; Operation maintenance convenience, failure rate is low, safe and reliable.The utility model can be contained on various pipelines, can utilize in daily life the pressure of running water to make gas-liquid mixed water, and microvesicle occurs.Itself need not the power such as electric power device, can arbitrarily arrange, and is easy to use, very environmental protection.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 be in Fig. 1 A-A to view.
The specific embodiment
A kind of microvesicle generators as shown in Figure 1, comprise fluid inlet section 1, intake section 2, air chamber 3, gas-liquid mixed section 4, pore section 5 and fluid issuing section 6, the microvesicle generators center from left to right is sequentially with the fluid inlet section 1 that is connected, gas-liquid mixed section 4 and fluid issuing section 6 successively, the outer intake section 2 that is provided with of fluid inlet section 1, intake section 2 communicates with the air chamber 3 that is arranged on along shell 7 inwall surroundings, and air chamber 3 is connected with fluid inlet section 1 by pore section 5.
Fluid inlet section 1 is cone, the diameter of front end is greater than the diameter of rear end, gas-liquid mixed section 4 is cylinder, fluid issuing section 6 is cone, the diameter of front end is less than the diameter of rear end, pore section 5 is centripetal, and hole diameter is 0.5-1mm along being evenly distributed on air chamber 3 bottoms week, and intake section 2 is centered close to the front end of fluid inlet section 1 or the optional position between rear end or front and back end.
This device enters fluid inlet section 1 when the certain fluid of flow certain pressure (2.0~4.0kg/cm2 atmospheric pressure) is lower, begin to accelerate, during to gas-liquid mixed section 4, fluid reaches peak flow rate (PFR), and this moment, pressure diminished, and mineralization pressure is poor between fluid inlet section 1 and gas-liquid mixed section 4.This pressure differential becomes suction, gas is continuously pulverized by fluid by intake section 2, air chamber 3, pore section 5 and is sucked into fluid under the effect of this suction, become gas liquid mixture and flow out gas-liquid mixed section 4, then spray to atmosphere (comprising water body) through fluid issuing section 6.And will contain a large amount of microvesicles and nanometer bubble in this gas liquid mixture.
Operation principle: according to Venturi effect and Bernoulli's theorem, the sectional area that changes stream improves flow velocity, reduces pressure, and microvesicle occurs.At certain pressure (2.0~4.0kg/cm 2Atmospheric pressure) under, when the certain fluid of flow enters fluid inlet section 1, begin to accelerate, during to gas-liquid mixed section 4, fluid reaches peak flow rate (PFR), and this moment, pressure diminished, and mineralization pressure is poor between fluid inlet section 1 and gas-liquid mixed section 4.This pressure differential becomes suction, gas is continuously pulverized by fluid by intake section 2, air chamber 3, pore section 5 and is sucked into fluid under the effect of this suction, become gas liquid mixture and flow out peak flow rate (PFR) section, again through fluid issuing section 6 to atmosphere (comprising water body) ejection, and will contain microvesicle and the nanometer bubble of considerable amount in this gas liquid mixture.
