Abstract

The utility model relates to a large flow camber filling which is used to fix in the distillation column in chemical industry to increase the handling capacity of the vapor and liquid. The corrugated section of the filling is processed to the shape of half-round camber, the end face has a straight passage and the corrugation arranges in the shape of 'S'. The utility model has compact and reasonable structure; the triangle of the original corrugated filling is cut off to form a half-round camber, the liquid-retaining dead corner at the closed angle is changed into ordinary liquid membrane passage, which changes the direction of the passage and reduces the stagnant zone; F factors are improved and the flooding point is increased, which reduces the impedance of gas; the flow of the liquid and the contact surface of the vapor and liquid are increased, which improves the separation efficiency, thus increasing the handling capacity of the vapor and liquid of the distillation column of the same diameter.

Description

Big flow circular arc filler

Technical field:

The utility model relates to a kind of big flow circular arc filler, is used to be installed in the chemical industry destilling tower, increases the vapour-liquid treating capacity.

Background technology:

Before the utility model is made, in prior art, because the ripple inclination angle of filler is 30-45 °, become 30-45 ° inclination angle with the end face of filler, the direction of the every when mounted dish filler of filler is to turn to be mutually 90 ° of positions, the contact position of such two dish fillers has formed 60-90 ° of angle between the oblique ripple up and down, has on the corner become the delay band of liquid, has formed stagnant liquid dead angle.The experiment proved that the liquid flooding starting point of liquid just begins at the contact-making surface of two dish fillers.The filler fluid flow of this kind structure is little, and the gas-liquid contact-making surface is little, and air resistance is big, is difficult to improve separative efficiency.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned weak point, thereby the cross sectional shape that a kind of ripple is provided is a semicircular arc, the stagnant liquid dead angle of sharp corner is become the liquid film passage, thereby reach the minimizing air resistance, increase liquid flux, and can increase the contact surface of gas-liquid, reach the big flow circular arc filler that improves separative efficiency.

Main solution of the present utility model is achieved in that

It mainly adopts the ripple cross section of filler 1 to make semicircular arc, and its end face is made as craspedodrome passage 2, and corrugation rows is classified S shape 3 as.

Compared with the prior art the utility model has the following advantages:

The utility model compact conformation, reasonable; The angle that removes triangle on the basis of original ripple packing is a circular arc, and the stagnant liquid dead angle of wedge angle edges and corners is become common liquid film passage, has changed its channel direction, has deducted to be detained band; Improve the F factor, improved flooding point, reached the minimizing air resistance; Increased the flux of liquid, increased the contact surface of gas-liquid, reached and improved separative efficiency, thereby made destilling tower in same tower diameter, increase the vapour-liquid treating capacity.

Description of drawings:

Fig. 1 is the utility model packing box structural representation;

Fig. 2 is the utility model filler circular arc A-A profile;

The specific embodiment:

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

The ripple of the utility model filler 1 adopts semicircle to connect on the contrary, the cross sectional shape that is to say ripple is a semicircular arc, the close biend ripple inclination angle of filler, progressively turn to end face and become 90 °, its end face is made as craspedodrome passage 2, corrugation rows is classified S shape 3 as, with flow direction be parallel direction (equidirectional up and down) with tower body.Like this, each ripple all is circular the connection between two blocks of fillers, the conduit wall of two dishes has become straight channel pipe shape in no shadow up and down, (how many degree tube packing does not turn over, all be the same), under this spline structure, two dish filler contact end faces are delay bands that the largest passages place has made it to cancel generation liquid in the ripple, thereby have increased the flow of liquid.It has surpassed the flux of oblique ripple passage fully, becomes the passage place by original delay band, and this access ramp has just been brought into play effect widely, thereby than the liquid flux that has improved 10-25% on the original basis, makes it to reach the purpose of big flux.

Claims

1, a kind of big flow circular arc filler comprises filler (1), it is characterized in that adopting the ripple cross section of filler (1) to make semicircular arc, and its end face is made as craspedodrome passage (2), and corrugation rows is classified S shape (3) as.
