19th century mineral float glass process to be widely used be that people expect by identical principle, sewage being purified, in the thirties in 20th century, the report that has occurred flotation waste water treatment, along with going deep into of research, the fifties in last century, use By Bubble-floating Method to carry out extensive drink water purifying and all generally use in a lot of countries.Be applicable to the microvesicle diameter of water treatment generally at 10～80 microns, in flotation waste water treatment, use at present air soluble method is separated out more widely microvesicle diameter between 10～120 microns,, but its equipment requirements is completely airtight, makes processing unit comparatively complicated.The shortcomings such as the foaming of electrolysis and ultrasonic wave can produce the less and uniform microvesicle of diameter, but that electrolytic process and supersonic method exist power consumption is more, and cost is higher, so seldom used in flotation waste water treatment.Microporous foam method is a kind of comparatively economic foaming mode, microporous foam method is used micro-pore diameter for being generally several microns to tens microns, but the microvesicle producing due to adjacent micropore probably merges mutually, diameter generally can surpass tens times, aperture and arrive hundreds of times, does not many times reach desirable microvesicle diameter.
In aquaculture, in frequentation water, pass into microvesicle to increase the oxygen level in water, after a certain amount of air passes in water and the ability of the larger water dissolution of the contact area oxygen of water stronger, make contact area larger, require microvesicle diameter less.The microvesicle diameter passing in water in aquaculture is at present all larger, and the dissolved efficiency of oxygen is low especially, therefore need to reduce to pass into the diameter of air micro-bubbles, to improve the dissolved efficiency of oxygen.
Common micropore produces in the method for gas microvesicle, although single micropore can produce less microvesicle, but numerous micropores produces microvesicle simultaneously, because the distance between micropore is less, the process that reaches ripe volume at microvesicle will merge mutually, and the larger microvesicle of final formation can not meet desired microvesicle size.
Common micropore produces in the method for gas microvesicle, the minimum microvesicle diameter that the micropore of certain size produces is certain, gas is by producing friction with micropore wall in micropore process, consumed energy, expect that the microvesicle that size is less will select the micropore that size is less, therefore increased the consumption of energy.
Utility model content
The purpose of this utility model is to provide a kind of microvesicle generators, solves that existing microvesicle generators energy consumption is high, microvesicle easily assembles and cause the excessive problem of microvesicle diameter.
The technical scheme that the utility model is carried is: a kind of microvesicle generators, comprises base, vibrator, web member, chamber groove, poromerics, pressed gas inlet tube, sinking support; Described vibrator is fixed on base, and poromerics is fixed on chamber groove and forms chamber, and vibrator is connected by web member with chamber groove, and chamber groove is fixed on base by sinking support, and pressed gas inlet tube is fixed on chamber groove and is communicated with chamber.
Further, described pressed gas inlet tube is provided with air flow controller and tensimeter.
Further, the micro-pore diameter of described poromerics is 0.1 μ m～100 μ m
Further, described base consists of base plate and riser, and whole L-shaped, described vibrator is fixed on riser, and sinking support is fixed on base plate.
Further, described sinking support is spring.
The utility model is used the frequency vibrator adjustable with amplitude being fixed on base to be connected the chamber groove that poromerics is housed, chamber groove is fixed on base by sinking support, by pressed gas inlet tube to the gas that passes into certain pressure in chamber, on poromerics surface, produce microvesicle, be excited at the same time device work and drive chamber groove to vibrate back and forth in equilibrium theory of tide, now liquid produces the aperture that departs from poromerics before shearing action makes microvesicle reach ripe volume and in liquid, forms microvesicle on poromerics surface.Because need to not continuing to provide from outside liquid, it does not form shear flow, therefore along with the increase of microvesicle quantity, gas holdup in liquid rises gradually, until meet the requirements of gas content, and because of can adjusting vibration exciter frequency and amplitude, micropore orifice diameter and gas to chamber pressure control microvesicle diameter, thereby the diameter that can obtain is at the microvesicle of 0.05～5mm.
Compared with the existing technology, the utility model has the following advantages:
1, common micropore produces in the method for gas microvesicle, although single micropore can produce less microvesicle, but numerous micropores produces microvesicle simultaneously, because the distance between micropore is less, the process that reaches ripe volume at microvesicle will merge mutually, and the larger microvesicle of final formation can not meet desired microvesicle size.In the utility model, increased vibrator, microvesicle is not also grown up to contacting and just enter in water with adjacent microvesicle, greatly reduces the probability that microvesicle merges, and can access the comparatively desirable microvesicle of size.
2, common micropore produces in the method for gas microvesicle, the minimum microvesicle diameter that the micropore of certain size produces is certain, gas is by producing friction with micropore wall in micropore process, consumed energy, expect that the microvesicle that size is less will select the micropore that size is less, therefore increased the consumption of energy.In the utility model, increase after vibrator, can under larger micropore size, produce less microvesicle, reduced the frictional dissipation of gas and micropore, under some operating mode, although increased the power consumption of vibrator, overall power consumption reduces.
3, common micropore produces in the method for gas microvesicle, and micropore size can not infinitely reduce, and in the utility model, uses vibrator can obtain not reaching microvesicle diameter in the situation that only using poromerics.
4, compare with electrolytic process, supersonic method and air soluble method, although they can produce the less and uniform microvesicle of diameter, electrolytic process and supersonic method power consumption are more, and cost is higher; Air soluble method is because air dissolves degree is compared with little and easily occur the phenomenon of air voids deficiency.And the cost of the microvesicle that the utility model produces is low, air voids can increase poromerics outer surface area and time expand is controlled.
5, compare with other microvesicle production methods, the microvesicle diameter range that this utility model can obtain by adjustment velocity of shear (amplitude of vibrator and frequency), micro-pore diameter, chamber internal gas pressure is wider, is suitable for various different operating modes.
