Description
Technical field
The invention belongs to the chemical machinery technical field, relate to a kind of physical defoaming device, especially a kind of device for the liquid froth breaking.
Background technology
In the process of preparation nano-calcium carbonate, dispersed preferably in order to obtain, usually need to add surfactant and coat processing.But common surfactant is again typical foaming agent, can generate a large amount of foams in slurries, follow-up technological operation has been caused seriously influence.Exactly these slurries are carried out 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 the dispersion of discontinuous phase (spherical) in liquid, and gas occupied most of volume, only isolated by very thin liquid film between the bubble.When two bubbles that vary in size contacted, because the pressure of vesicle inside is large, through the contact action of certain hour, gas moved to bulla by liquid film, is merged at last a larger bubble.And foam is in case form, because low with respect to liquid system of density rises to liquid level gradually under the effect of buoyancy.When speed that the formation speed of bubble is broken greater than bubble, will pile up, finally form foam, and passing in time and increasing, thereby harm formed.
In the froth breaking process, generally mainly contain two kinds of froth breaking modes, one is chemical froth breaking, namely adds the defoamer froth breaking, and one is physical defoaming, namely uses mechanical defoaming device, and perhaps two kinds of froth breaking modes are also used.Adding defoamer is now widely used a kind of method, and it is to add a certain amount of suitable defoamer in material, has changed the material table surface tension, reduces or has suppressed foaming, thereby reach the froth breaking purpose.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 pollution to product, can utilize continuously, some simple and easy froth breakers particularly, it is low to consume energy, and can reach the effect of low-cost high-efficiency.
At present, in fermentation, pulping and paper-making, hydraulic oil, sewage disposal and some food such as the industries such as soya-bean milk, honey, mostly can use froth breaker.Old-fashioned froth breaker generally is furnished with agitator, motor etc., and compression chamber that uses froth breaking oar or High Rotation Speed etc. smashes foam more, generally all needs very high-powerly just can play preferably defoaming effect.And in the actual production process, its defoaming effectiveness is lower, so be eliminated gradually.The froth breaker simple, that 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 the character of bubble and state and stacked situation froth breaking.Chinese invention patent CN 102410285A has introduced a kind of can preventing and has produced bubble when high-volume hydraulic oil from 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, and manufacturing process's difficulty is invested higher.
So far, by consulting data of literatures, we find that not yet a energy effective application is in the froth breaker of nano-calcium carbonate industry.In order to address this problem, the invention provides a kind of defoaming device for the calcium carbonate industry.
Summary of the invention
Purpose of the present invention: comparatively complicated at present existing defoaming equipment structure, manufacturing process's difficulty is invested higher shortcoming, and a kind of simple device for the liquid froth breaking is provided.
Technical scheme of the present invention is:
Utilizing foam is the solution-air non-individual body that the very thin liquid film of one deck surrounds gas, foam on the liquid level is usually by the organic principle in the liquid, be that surfactant is kept its stability, and if any liquid that contains surfactant not with contact with air, the principle that just can not bubble.And utilize the energy of introducing at the 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 the fluid transport process, reduces the contact of liquid-to-air as far as possible, and the impact energy of introducing when reduce liquid flows into the gas-liquid contact face simultaneously suppresses the generation of foam to greatest extent.
In order to realize the above-mentioned defoaming effect of mentioning, the technical solution used in the present invention is:
A kind of device for the liquid froth breaking comprises liquid storage tower, defoaming tower, feed pipe and discharge nozzle are set, and it is characterized in that: defoaming tower is located in the 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 evenly arranges spillway hole all around on the wall of middle hypomere, the aperture of spillway hole is Φ 1-4mm, and spillway hole arranges more than three rows, and the gross area of spillway hole is greater than the sectional area of feed pipe.
The tip position of above-described feed pipe in defoaming tower arrange than defoaming tower the highest one row the high 5-20cm of spillway hole, feed pipe arranges flowmeter and valve A at 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 the liquid storage tower.
This device is applicable to the large and little liquid froth breaking of viscosity of viscosity.
Beneficial effect of the present invention is:
1, the aperture evenly to be set around on the wall of middle hypomere be Φ 1-4mm spillway hole to the defoaming tower that arranges of this device, and liquid storage tower, defoaming tower, feed pipe are arranged on the same axle center, form the liquid fluid system of sealing, and liquid foam can effectively disappear.
2, this apparatus structure is simple, processing ease, and small investment, the liquid defoaming effect is good, is applicable to the large and little liquid froth breaking of viscosity of viscosity, has preferably economic benefit.
