Abstract
A kind of tower tray for liquid nitrogen wash process it comprise plate column and perforate, plate column is sieve-plate tower (1), sieve-plate tower (1) has rectangle tongue nibs (2), the perforate direction of rectangle tongue nibs (2) is towards downflow weir (3), and the blowing angle of rectangle tongue nibs (2) from downflow weir (3) to the other end successively from small to large.It is good that the utility model has mass transfer effect, and veneer pressure drop is little, and structure is simple, installs and be easy to advantage.
Description
Technical field
The utility model relates to a kind of tower tray for liquid nitrogen wash process.
Background technology
Nowadays identical for the sieve tray opening angle of liquid nitrogen washing device and opening mode is the same, when making that near tower tray downspout, liquid layer is thicker in mass transport process, mass transfer is uneven, and in existing liquid nitrogen wash process there is top tower tray pressure drop comparatively greatly in scrubbing with liquid nitrogen tower, the shortcoming that mass-transfer efficiency is low.
Summary of the invention
The object that this practicality is sent out novel is the shortcoming for prior art, and provide a kind of structure simple, tower tray pressure drop is little, the tower tray for liquid nitrogen wash process that mass transfer effect is good.
The object that this practicality is sent out novel is realized by following technological means:
The utility model by perforate towards downflow weir, and the feature that opening is less, realize Liquid Flow direction mutually vertical, improve mass transfer effect as far as possible, by the method that opening angle promotes gradually, the tower tray realized from downflow weir exit liquid layer is thicker also has good mass transfer effect.
A kind of tower tray for liquid nitrogen wash process, it comprises plate column and perforate, it is characterized in that plate column is sieve-plate tower, and sieve-plate tower has rectangle tongue nibs, the perforate direction of rectangle tongue nibs towards downflow weir, the blowing angle of rectangle tongue nibs from downflow weir to the other end successively from small to large.
The blowing angle of rectangle tongue nibs as above increases by 0.5 ° step by step successively from small to large successively from downflow weir to the other end
The utility model compared with prior art has following obvious advantage: mass transfer effect is good, and veneer pressure drop is little, and structure is simple, installs easily.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 of the present utility modelly installs and uses figure.
As shown in the figure, 1 is sieve-plate tower, and 2 is rectangle tongue nibs, and 3 is downflow weirs, and 4 is rectifying column housings.
Detailed description of the invention
Illustrate that the present invention is described in further detail with detailed description of the invention below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of tower tray for liquid nitrogen wash process, it comprises plate column and perforate, it is characterized in that plate column is sieve-plate tower 1, sieve-plate tower 1 has rectangle tongue nibs 2, the perforate direction of rectangle tongue nibs 2 is towards downflow weir 3, the blowing angle of rectangle tongue nibs 2 increases by 0.5 ° from downflow weir 3 successively from small to large successively step by step to the other end, as shown in Figure 2, tower tray is in running, rectifying column housing 4 side to fall liquid layer thicker, rectangle tongue nibs 2 opening is 21 °, the opening magnified provides more ascending vapor to realize mass transfer, near downflow weir 3, liquid layer is thinner, rectangle tongue nibs 2 opening is 19 °, ascending vapor amount is less relative to the former, thus realize whole tower tray mass transfer and be evenly distributed.And due to tray structure simple, handling ease, is applicable to low temperature liquid nitrogen and washes use in technique in nitrogen wash column.
Claims (2)
1. the tower tray for liquid nitrogen wash process, it comprises plate column and perforate, it is characterized in that plate column is sieve-plate tower (1), sieve-plate tower (1) has rectangle tongue nibs (2), the perforate direction of rectangle tongue nibs (2) is towards downflow weir (3), and the blowing angle of rectangle tongue nibs (2) from downflow weir (3) to the other end successively from small to large.
2. a kind of tower tray for liquid nitrogen wash process as claimed in claim 1, is characterized in that the blowing angle of described rectangle tongue nibs (2) increases by 0.5 ° from downflow weir (3) from small to large successively step by step to the other end.
