Abstract

The utility model discloses an anti-blocking device of a sieve plate for a flash tower for crude biodiesel, wherein an overflow distribution pipe (3-1) is installed on a sieve plate (3) in a flash tower body (1); the distribution pipe is provided with uniformly distributed small holes; the diameters of the lower layer of the sieve plates are bigger than that of the adjacent upper layer of the sieve plates; the upper edge of each sieve plate is tooth-shaped (3-2). The anti-blocking device of sieve plate for flash tower for crude biodiesel disclosed in the utility model can increase uniformity of liquid of the lower layer sieve plate when redistributed, overcome liquid distributivity from being influenced by blockage of the overflow distribution pipe, and increase heat conduction area, shorten vaporization time and raise flashing evaporation effect.

Description

Coarse biodiesel flashing tower sieve plate preventing clogging up device
One, technical field
The utility model relates to the coarse biodiesel flashing tower sieve plate preventing clogging up device in organic the Chemicals production unit, particularly biodiesel production facility.
Two, background technology
Owing to contain small amount of methanol, glycerine, fatty acid soaps, short chain fatty acid methyl esters and other impurity in the coarse biodiesel; Must go out above-mentioned impurity through fractionation by distillation; Wherein low-boiling-point substance such as methyl alcohol generally separates through flashing tower, to reach standard compliant biofuel goods.Coarse biodiesel flashing tower sieve plate preventing clogging up device is the flashing tower important component part, and whether this apparatus structure rationally directly influences the flash distillation effect of flashing tower, thereby has influence on the normal operation of Distallation systm, and then influences biofuel quality and production energy consumption.The coarse biodiesel flashing tower sieve plate (column plate) of prior art has at the sieve plate layer and is provided with upflow tube and does not establish two kinds of structures of upflow tube, and their blocking devices of generally not setting up defences are not enough below this flashing tower sieve plate exists:
A, for the sieve plate of not establishing the upflow tube device because coarse biodiesel contains other impurity such as fatty acid soaps, sieve plate uses easy blocking after for some time in the flashing tower, makes the liquid can not be with droplet-like toward current downflow, heat interchanging area is little, the flash distillation effect is relatively poor.
B, for the sieve plate that the upflow tube device is arranged, if the upper strata sieve plate stops up,, have still that to be by convection into lower floor's sieve plate distribution of liquid property poor though liquid can flow to lower floor's sieve plate through upflow tube, lower floor's sieve plate liquid is through inhomogeneous.
Three, summary of the invention
The purpose of the utility model provide a kind of when improving the redistribution of lower floor sieve plate liquid homogeneity, overcome because of overflow distribution pipe congestion affects Liquid Distribution property, increase heat transfer area, shorten vaporization time, improve the coarse biodiesel flashing tower sieve plate preventing clogging up device of flash distillation effect.
For realizing above purpose; The utility model coarse biodiesel flashing tower sieve plate preventing clogging up device is that the overflow distribution pipe is installed on the sieve plate in the flash distillation tower body; Distribution pipe is provided with equally distributed aperture, and adjacent sieve plate diameter lower floor is greater than the upper strata, and the upper limb of each sieve plate is profile of tooth.
Said structure coarse biodiesel flashing tower sieve plate preventing clogging up device has following characteristics and effect:
The one, adopted the overflow distribution pipe of being with the uniform distribution aperture in this device, improve lower floor's sieve plate liquid redistribution homogeneity, increased heat transfer area, shortened vaporization time, improve the flash distillation effect; The 2nd, influence Liquid Distribution property in order to prevent the overflow distribution pipe from stopping up; The profile of tooth breach is made at every layer of sieve plate edge; And lower floor's sieve plate is bigger slightly than adjacent upper sieve board diameter, and when the overflow distribution pipe stopped up, the liquid of upper strata sieve plate also can be from the profile of tooth breach; Flow to lower floor's sieve plate with droplet-like, reach the purpose that improves the flash distillation effect equally.
Four, description of drawings
Accompanying drawing 1 is the utility model coarse biodiesel flashing tower sieve plate preventing clogging up device structural representation.
Five, embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Shown in the accompanying drawing; The utility model coarse biodiesel flashing tower sieve plate preventing clogging up device is that overflow distribution pipe 3-1 is installed on the sieve plate 3 in flash distillation tower body 1; Distribution pipe is provided with the aperture that is evenly distributed, and adjacent sieve plate diameter lower floor is greater than the upper strata, and the upper limb of each sieve plate is profile of tooth 3-2.
During operation; Open with low-boiling-point substance and export the vacuum system that 1-1 is connected, after flashing tower reaches the certain vacuum degree, coarse biodiesel is imported or sprayed in the flashing tower on the sieve plate 3 through feed-pipe 2 continuously with pump; Liquid flows from top to down; Low-boiling-point substance step-downs such as methyl alcohol vaporizations is resolved the back and is extracted out from low-boiling-point substance outlet 1-1, reaches and the isolating purpose of biofuel, and the material that removes behind the low-boiling-point substance such as methyl alcohol is discharged from biofuel outlet 1-2.Owing to contain other impurity such as fatty acid soaps in the coarse biodiesel, after work for some time, the sieve plate aperture possibly stopped up by part, and liquid level rises to riser in the sieve plate, after the redistribution of overflow distribution pipe, is the drop form to flow to lower floor's sieve plate; If the upflow tube exit portion is stopped up, liquid flows to diameter than on the big slightly lower floor's sieve plate of this layer sieve plate from sieve plate upper limb profile of tooth breach with the drop form, thereby guarantees the homogeneity and the validity of sieve plate Liquid Distribution, improves the flash distillation effect.
