Description

A kind of device for liquid froth breaking
Technical field
The invention belongs to chemical machinery technical field, relate to a kind of physical defoaming device, especially a kind of device for liquid froth breaking.
Background technology
In the process of preparing nano-calcium carbonate, in order to obtain good dispersiveness, conventionally need to add surfactant to be coated processing.But common surfactant is again typical foaming agent, can in slurries, generate a large amount of foams, follow-up technological operation has been caused to serious impact.Exactly these slurries are carried out to defoaming treatment and address this problem unique approach.
Thermodynamic argument is thought: the foam that neat liquid produces can only of short duration existence of short time, and is dissolved with the liquid of impurity, but has to strengthen the tendency of bubbling, and makes foam become lasting and stablize.Foam be gas as discontinuous phase (spherical) dispersion in liquid, and gas occupied most of volume, between bubble, only isolated by very thin liquid film.In the time that two bubbles that vary in size contact, because the pressure of vesicle inside is large, through the contact action of certain hour, gas moves to bulla by liquid film, is finally merged into a larger bubble.Once and foam forms, due to low with respect to liquid system of density, rise to gradually liquid level under the effect of buoyancy.In the time that the formation speed of bubble is greater than the speed that bubble breaks, will pile up, finally form foam, and passing in time and increasing, thereby harm formed.
In froth breaking process, generally mainly contain two kinds of froth breaking modes, one is chemical froth breaking, adds defoamer froth breaking, one is physical defoaming, uses mechanical defoaming device, or two kinds of froth breaking modes are also used.Adding defoamer is a kind of now widely used method, and it is in material, to add a certain amount of applicable defoamer, has changed material table surface tension, reduces or has suppressed foaming, thereby reaching froth breaking object.Defoamer is expensive, uses defoamer not only to expend fund, and can affect performance or the polluted product of product, and this method cost-effective rate is low.Use mechanical defoaming device can get rid of the pollution to product, can utilize continuously, particularly some simple and easy froth breakers, consume energy low, can reach the effect of low-cost high-efficiency.
At present, fermentation, pulping and paper-making, hydraulic oil, sewage disposal and some food as the industry such as soya-bean milk, honey in, mostly can use froth breaker.Old-fashioned froth breaker is generally furnished with agitator, motor etc., and compression chamber that uses froth breaking oar or High Rotation Speed etc. smashes foam more, generally all needs the very high-power good defoaming effect that just can play.And in actual production process, its defoaming effectiveness is lower, so be eliminated gradually.The froth breaker simple, energy consumption is low, effective is only the optimal selection that enterprise enhances productivity.Chinese utility model patent ZL 200620095219.5, CN 202054838U disclose respectively " a kind of flying saucer type centrifugal defoamer " and " a kind of defoaming device " applies to fermentation industry, and its operating load is little, defoaming effectiveness is high.How effectively Chinese invention patent CN 102442708A provides a kind of froth breaker of wastewater treatment, no matter character and state and the stacked situation froth breaking of bubble.Chinese invention patent CN 102410285A has introduced one can prevent that high-volume hydraulic oil from producing bubble while getting back to fuel tank, reduces the super-high flow return-oil defoamer of oil contamination.These froth breakers are easier than old-fashioned froth breaker froth breaking mode, and defoaming effectiveness is high.But these froth breaker structures are comparatively complicated, manufacturing process's difficulty, invests higher.
So far, by consulting data of literatures, we not yet find a froth breaker that can effectively be applied to nano-calcium carbonate industry.In order to address this problem, the invention provides a kind of defoaming device for calcium carbonate industry.
Summary of the invention
Object of the present invention: comparatively complicated at present existing defoaming equipment structure, manufacturing process's difficulty, invests higher shortcoming, and a kind of simple device for liquid froth breaking is provided.
Technical scheme of the present invention is:
Utilizing foam is the solution-air non-individual body that liquid film that one deck is very thin surrounds gas, foam on liquid level is conventionally by the organic principle in liquid, be that surfactant maintains its stability, and if any liquid that contains surfactant does not contact with air, the principle that just can not bubble.And utilize the energy of introducing at gas-liquid contact face as far as possible little, effectively suppress the principle of the generation of foam.Method of the present invention adopts in fluid transport process, reduces the contact of liquid-to-air as far as possible, reduces as much as possible the impact energy of introducing when liquid flows into gas-liquid contact face simultaneously, suppresses to greatest extent the generation of foam.
In order to realize the above-mentioned defoaming effect of mentioning, the technical solution used in the present invention is:
For a device for liquid froth breaking, comprise liquid storage tower, defoaming tower, feed pipe and discharge nozzle are set, it is characterized in that: defoaming tower is located in liquid storage tower, on the same axle center of liquid storage tower and defoaming tower, feed pipe is set; Described discharge nozzle is located at the bottom of liquid storage tower or the side of hypomere, and effective control valve is set, and discharge nozzle and/or overflow pipe arrange respectively valve and be connected with outer liquid pool.
Above-described defoaming tower surrounding on the wall of middle hypomere evenly arranges spillway hole, and the aperture of spillway hole is Φ 1-4mm, and more than spillway hole arranges three rows, the gross area of spillway hole is greater than the sectional area of feed pipe.
Arranging than the highest row's of defoaming tower the high 5-20cm of spillway hole of the tip position of above-described feed pipe in defoaming tower, feed pipe arranges flowmeter and valve A in feed liquor one end, and is connected with circulating pump.
Arranging than the high 2-10cm of liquid storage liquid level of the tip position of above-described overflow pipe in liquid storage tower.
This device is applicable to viscosity greatly and the little liquid froth breaking of viscosity.
Beneficial effect of the present invention is:
1, it is Φ 1-4mm spillway hole that defoaming tower surrounding on the wall of middle hypomere that this device arranges evenly arranges aperture, and liquid storage tower, defoaming tower, feed pipe are arranged on same axle center, forms the liquid fluid system of sealing, and liquid foam can effectively disappear.
2, this apparatus structure is simple, processing ease, and small investment, liquid defoaming effect is good, is applicable to viscosity greatly and the little liquid froth breaking of viscosity, has good economic benefit.
