Abstract
The utility model relates to a centrifugal spray drying system which comprises a spray drying tower, a cyclone separator and a draft fan, wherein the cyclone separator consists of a barrel body and an exhaust pipe extending into the barrel body, a gas inlet which is connected with the lower part of the spray drying tower is arranged at the top part of the barrel body, the exhaust pipe is connected with the draft fan, the air outlet of the draft fan is connected into a washing tank, water distributors are uniformly distributed at the upper part of a tank body thereof and can spray water fog to air containing a potassium sorbate powder so as to enable the potassium sorbate powder to be dissolved in water, the water dissolved with potassium sorbate can form a water pump of a circulating loop by being connected with the water distributors, enter the water distributors again, repeatedly and continuously adsorb the potassium sorbate powder in the air and can be used for producing the potassium sorbate next time, thereby enhancing the utilization ratio of resources.
Description
Technical field
The utility model relates to a kind of centrifugal spray dryer drying system, comprise spray drying tower, cyclone separator and air-introduced machine, described cyclone separator is made of cylindrical shell and the blast pipe that stretches in the cylindrical shell, and the cylindrical shell top has the air inlet that is connected with the spray drying tower bottom, and blast pipe is connected with air-introduced machine.
Background technology
Potassium sorbate needs will contain in the liquid feeding centrifugal spray dryer drying system of potassium sorbate in process of production, is dried to the potassium sorbate granule of powdery.The centrifugal spray dryer drying system is made up of spray drying tower, cyclone separator and air-introduced machine usually, with hot-air with contain in the tower still that potassium sorbate solution imports spray drying tower, contain potassium sorbate solution and at high temperature flash to the discharging opening that the potassium sorbate powder falls into tower still bottom, steam then separates along with hot-air enters cyclone separator from the tower still once more with the part potassium sorbate powder, and steam is discharged by the air-introduced machine that is connected with cyclone separator.And because cyclone separator carries out existing when the potassium sorbate powder separates with steam and separates halfway problem, the part potassium sorbate powder can be discharged from air-introduced machine along with steam, not only causes the waste of raw material, has also polluted working environment.
The utility model content
The technical problems to be solved in the utility model provides a kind of centrifugal spray dryer drying system, can thoroughly reclaim and be dried to pulverous potassium sorbate, avoids the waste of resource and the pollution of environment.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of centrifugal spray dryer drying system, comprise spray drying tower, cyclone separator and air-introduced machine, described cyclone separator is made of cylindrical shell and the blast pipe that stretches in the cylindrical shell, the cylindrical shell top has the air inlet that is connected with the spray drying tower bottom, blast pipe is connected with air-introduced machine, its innovative point is: the exhaust outlet of described air-introduced machine inserts washing tank, the top of described washing tank has air outlet, top is evenly distributed with water-locator, the bottom connects and composes a closed circuit by water pump and water-locator, and also is fixed with curved baffle below air outlet.
Advantage of the present utility model is: the air that contains the potassium sorbate powder enters in the washing tank under the effect of air-introduced machine, water-locator carries out spray water to it, make that the potassium sorbate powder is soluble in water, the water that is dissolved with potassium sorbate can enter water-locator once more by water pump and spray, absorb airborne potassium sorbate powder so continuously, the water that is dissolved with the potassium sorbate powder can be used for the industrial water of next potassium sorbate, has improved the utilization rate of resource.Curved baffle can prevent to contain the air of potassium sorbate powder and directly discharge through the air outlet on washing tank top.
Description of drawings
Accompanying drawing is the structural representation of centrifugal spray dryer drying system of the present utility model.
The specific embodiment
As shown in drawings, the utility model relates to a kind of centrifugal spray dryer drying system, comprises spray drying tower 1, cyclone separator 2, air-introduced machine 3, air inlet 5, blast pipe 6, washing tank 4, water-locator 7, air outlet 8, curved baffle 9, water pump 10.
The solution and the hot-air that contain potassium sorbate feed in the tower still of spray drying tower 1, and under the effect of potassium sorbate solution at hot-air of atomizing, the moisture in the solution is evaporated, and it is Powdered to make potassium sorbate be dried to.Most of potassium sorbate powder falls in the aggregate bin of spray drying tower 1 bottom, and another part potassium sorbate powder enters in the cyclone separator 2 that is connected with spray drying tower 1 bottom with air and steam.These cyclone separator 2 main bodys are the cylindrical shell of top column type lower cone shape, the top of this cylindrical shell is connected with air inlet 5 and blast pipe 6, blast pipe 6 stretches in the cylindrical shell from the top center of cylindrical shell, the air that contains potassium sorbate powder and steam enters from air inlet 5, air-flow enters mobile downwards along cylindrical shell twist, most of potassium sorbate powder is thrown toward inwall under centrifugal action, and under the gravity effect, falls to the bottom aggregate bin along inwall.The air of rotation shrinks to center flow under the effect of cylindrical shell 2 lower cone type inner chambers, upwards forms the secondary vortices blast pipe 6 of flowing through and flows out from the cylindrical shell top.Air-introduced machine 3 will still contain in the washing tank 4 of air suction one side of part potassium sorbate powder, the upper inside wall of this washing tank 4 is evenly distributed with water-locator 7, described water-locator 7 spray water in jar, make that airborne potassium sorbate powder is soluble in water, air is then discharged from the air outlet 8 at washing tank 4 tops, the below of air outlet 8 is fixed with a curved baffle 9, can delay the speed that air is discharged, and makes that airborne potassium sorbate powder can be soluble in water fully.The bottom of washing tank 4 is connected with water-locator 7 by water pump 10, the water that falls into washing tank 4 bottoms flows out from water-locator 7 once more through water pump 10, circulation so repeatedly, constantly absorb airborne potassium sorbate powder, it is soluble in water, the water that is dissolved with the potassium sorbate powder can be used as the industrial water of following batch of potassium sorbate, has improved the utilization rate of resource.
