Embodiment 1

[0046] First, according to actual working conditions, the radius of the first bottom plate 21 and the second bottom plate 22 is determined to be 365 mm, and the thickness C of the air guiding device 11 is selected to be 130 mm. The radius of the deflector 13 is half of the radius of the first bottom plate 21 , that is, 182.5mm. The number of deflectors 13 is selected as eight.

[0047] Then, according to actual working conditions, the thickness B of the volute 12 is initially determined to be 200mm, B:C=1:1.54, which is within the range of 1:1-1:5. Select the air inlet velocity U as 8m / s, and the gas volume flow rate V as 0.566m 3 / s, thus the width A of the air inlet 14 is calculated to be 350mm. B:A=1:1.75, within the range of 1:1-1:2.

[0048] Finally, an approximate Archimedes spiral is made according to the four-line involute spiral drawing method to obtain the shape of the circumferential side wall of the volute 12 .

[0049] It is found in actual use that the hot ai...

Abstract

The invention relates to a hot wind distributor which is used for converting horizontal inlet wind to vertical outlet wind. The hot wind distributor comprises a volute casing and a wind guiding device which is installed inside an inner chamber of the volute casing; the volute casing which is provided with a wind inlet limits the hollow inner chamber; the wind guiding device comprises a circular-ring-shaped first base plate and a circular-ring-shaped second base plate which are oppositely arranged in a parallel mode; a first taper sleeve and a second taper sleeve are arranged in central holes of the first base plate and the second base plate; a wind outlet is formed between the first cone sleeve and the second cone sleeve; a plurality of arc-shaped guide plates are arranged between the first base plate and the second base plate. The hot wind distributor has the advantages of being small in tail portion wind loss and enabling the hot wind to be uniformly and straightly distributed.

Description

technical field [0001] The present invention relates to tower type drying equipment, and more particularly relates to a hot air distributor in the tower type drying equipment. Background technique [0002] The hot air distributor is a key component for the uniform distribution of hot air on the spray drying tower. At present, the hot air distributor mainly has two structures of the volute horizontal perforated plate type and the volute fin type. Figure 1a and 1b Schematically shows the hot air distributor of these two structures, where Figure 1a It is a volute horizontal porous plate hot air distributor, Figure 1b It is a volute fin type hot air distributor. The arrows in the diagram show the direction of wind flow. [0003] In use, for the hot air distributor with volute horizontal perforated plate structure, the hot air first flows into the volute, and then enters the tower through the horizontal perforated plate. The hot air distributor with this structure will for...
