Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art under the premise of not making the creative labor it is obtained it is all its
His embodiment, shall fall within the protection scope of the present invention.
The object of the present invention is to provide a kind of cooling towers for cooling down the material in de- polypropylene after VOC, above-mentioned existing to solve
The problem of with the presence of technology, enables the material in de- polypropylene after VOC to be fully cooled.
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
A kind of cooling tower for cooling down the material in de- polypropylene after VOC, including shell are present embodiments provided as shown in Figure 1:
Body 4, shell 4 include upper housing interconnected and lower case, upper housing be it is rectangular, lower case is square cone, the shape of lower case
Shape is discharged after collecting convenient for material from material outlet 6.Upper housing upper end is provided with material inlet 5, and lower case lower end is provided with object
Material outlet 6, material outlet 6 is provided with rotary valve, and the flow of material is controlled in material discharge.Setting several layers are cold in upper housing
But pipe 2, every layer of cooling tube 2 are several, and several cooling tubes 2 are horizontal and are arranged in parallel.Shell 4 is stretched out at 2 both ends of cooling tube, cold
But one end of pipe 2 is cooling medium entrance 1, and the other end of cooling tube 2 is cooling medium outlet 3, the cooling being passed through in cooling tube 2
Medium is preferably cooling water.Cooling tube 2 is preferably rhumbatron, and rhumbatron, which can be avoided, material dead angle occurs inside shell 4, make object
Material can be fully cooled.The adjacent rhumbatron of the two neighboring rhumbatron of same layer and adjacent layer interlocks cloth in equilateral triangle
It sets, such arrangement ensure that material is uniformly distributed between diamond shape, and the amount of the material between each rhumbatron is identical, cooling equal
Even, rhumbatron comes into full contact with material, good cooling results.In the present embodiment, cooling medium entrance 1 and cooling medium export 3
Arrangement mode can be located at the cooling medium entrance of the same side or adjacent cooling tube 2 for several cooling medium entrances 1
