Description
Technical field
The present invention relates to a kind of defoaming separators.It is primarily adapted for use in disappearing for the foam generated in fermentation process
It removes, further relates to the needs such as solution concentration, the production of the pulp processing in paper-making process, lotion and weakened using defoaming separator, pressed down
System thoroughly eliminates the field that foam is just able to satisfy the needs of actual production.
Background technique
In fermentation process, fermentation production process largely be all it is aerobic, needed in its fermentation process
Filtrated air is constantly passed through into fermentor, along with mechanical stirring, air can be divided into many tiny bubbles, from dissolved oxygen
From the perspective of, the effect of the thinner dissolved oxygen of bubble is better, because the diameter of bubble is smaller, the specific surface area of gas-liquid contact is got over
Greatly, but these bubbles, which rise to, can be readily formed foam on fermentation liquid liquid level.And microorganism is when carrying out fermentation activity,
Often metabolism produces many gases, these metabolism gases condense to form bubble, rises to fermentation liquid level and forms barm.
However, the generation of a large amount of foams, which can produce technique, causes huge harm, such as reduces production capacity, influences product
Quality influences production and normally carries out etc., this just needs to be defoamed by various methods.There are commonly 2 kinds of defoaming modes:
Mechanical defoaming, chemistry defoaming.Defoaming agent is added as its name suggests to eliminate foam in chemistry defoaming, however is equal in this way in fermentation liquid
In joined impurity easily interfere microorganism growth and breeding or influence metabolite accumulation.Nowadays people mostly use greatly machinery
Defoaming, existing mechanical defoaming device are the installation defoaming rakes on agitating shaft, and defoaming rake is rotated together with agitating shaft, using disappearing
Bubble rake smashes foam.But defoaming rake can only smash a small amount of foam, defoaming effectiveness is very low.
Patent CN107176641A, a kind of spiral-flow type defoaming device, this spiral-flow type defoaming device include that an impeller guide disappears
Foam, the external setting tangential direction water conservancy diversion of impeller guide defoaming enter impeller guide and defoam intracorporal inflow entrance, which leads
Stream defoaming is provided with a foam in vivo and collects body, which collects and be equipped with power-actuated hairbrush froth breaker on body, defoaming effect
Fruit is more apparent.However, this equipment belongs to dynamic equipment, manufacture operating cost is higher, and the hairbrush froth breaker one side energy rotated
It enough smashes foam and realizes defoaming, its rotation can make solution generate new foam but then, will affect defoaming effectiveness.This sets
It is standby also to introduce extraneous gas, increase the risk of pollution.
Patent CN106754295A, a kind of fermentation stirring defoaming device, the invention are related to a kind of liquid fermentation stirring defoaming
Defoaming device and stirring blade, the invention benefit are fixed on device, including stepper motor, fermentor shell and motor shaft motor shaft
With pressure and with fermentation liquid Forced Mixing, foam is eliminated, defoaming effect is preferable, without side-effects, avoids pollution and produces
Raw possibility.However, the defoaming effectiveness of stirring defoaming device itself is relatively low, and smash also easy while bubble in fermentation liquid
Fermentation liquid is generated to new bubble, it is difficult to be used for industrial production.
Summary of the invention
The main object of the present invention is to provide a kind of new and effective defoaming separator, can effectively overcome above-mentioned traditional machine
The low problem of tool defoaming device defoaming effectiveness, it is not only economic and environment-friendly but also defoaming effectiveness height can be reused.
The technical solution adopted by the present invention is that: a kind of defoaming separator, it is characterised in that its process flow are as follows: storage tank
(1) foam in is drawn by suction bubbler (2), is steeped pipe (3) by inhaling and is entered defoaming separator (4) defoaming, separation, and liquid is from defoaming
The discharge of separator underflow opening returns to storage tank by separator tail pipe (6), and gas is discharged from defoaming separator overflow port.Inhale bubbler
(2) horizontally disposed to defoam separator (4) in height and position on the lower side in foam in storage tank and be located above storage tank, separator tail pipe
(6) liquid layer being inserted into storage tank.
Inhaling bubbler (2) is that the circular ring shape that round tube curves inhales bubble pipe, is uniformly provided with circular hole, aperture 4-6 on tube wall
Bubble mean diameter again.Defoaming separator (4) is cyclone separator, is made of one or more tornadotron (7).Rotation
When air hose (7) has multiple, it can be packed into a big cylinder.
The method of this defoaming separator is: aspirating the gas in defoaming separator by blower (5), makes entirely defoaming point
Negative pressure is generated from device.Due to the effect of pressure difference, foam is drawn by suction bubbler (2), steeps pipe (3) into defoaming separator by inhaling
(4).It is equipped with multiple tornadotrons (7) in defoaming separator, high speed rotation is after foam enters tornadotron to be able to achieve multistage
Gas-liquid separation.The liquid of final heavy phase returns to storage tank, light phase by separator tail pipe (6) from defoaming separator underflow opening discharge
Gas from defoaming separator overflow port discharge.
The invention has the beneficial effects that:
(1) present apparatus carries out foam using defoaming separator mechanically decoupled, will not generate pollution to fermentation liquid.
(2) present apparatus structure design advantages of simple, low manufacture cost, maintenance easy for installation can be realized automation control.
The operation that whole device is driven by blower brings foam into defoaming separator and carries out multi-stage separation, and separative efficiency obtains significantly
It improves on ground.
(3) present apparatus defoaming effect is obvious, and gas is discharged by separator overflow port after foam fraction factor, and fermentation liquid is logical
It crosses tail pipe and returns to storage tank, can be realized persistent loop defoaming.
(4) present apparatus is applicable not only to the defoaming of fermentation liquid, but also suitable for other necks such as sewage treatment, food production
Domain.

Specific embodiment
Following instance is not limited to the application range of the invention patent for illustrating the invention patent.
As shown in Figure 1, making entirely to defoam separator generation negative pressure by the gas in blower (5) suction defoaming separator.
Due to the effect of pressure difference, foam is drawn by suction bubbler (2), steeps pipe (3) into defoaming separator (4) by inhaling.Defoaming separation
It is equipped in device multiple tornadotrons (7), high speed rotation is after foam enters tornadotron to be able to achieve multistage gas-liquid separation.Finally
The liquid of heavy phase returns to storage tank from defoaming separator underflow opening discharge, by separator tail pipe (6), and the gas of light phase divides from defoaming
It is discharged from device overflow port.
As shown in Fig. 2, defoaming separator (4) by tornadotron (7), into bubble mouth (8), bottom heavy out (9), top light phase
Export (10), outer barrel (11) and column plate (12) composition.Foam is by entering defoaming separator into bubble mouth (8), then from tornadotron
(7) tangential inlet enters rotation and realizes gas-liquid separation.Light phase gas after separation is discharged from the top exit of defoaming separator,
Heavy phase fermentation liquid reenters fermentor through the discharge of bottom heavy out.
As shown in figure 3, tornadotron (7) is by underflow opening (7-1), conically shaped (7-2), cylinder (7-3) and overflow port (7-4) group
At.
