Abstract
The utility model relates to a rectification device for the methylal reaction. The rectification device comprises a rectification tower, wherein two feeding ports are formed in the rectification tower and comprise a methanol feeing port formed in the upper part and a methyl alcohol feeding port formed in the lower part; the methanol feeding port extends into the rectification tower to form a liquid distributing pipe; and a plurality of spray nozzles communicated with the liquid distributing pipe are arranged at the lower part of the liquid distributing pipe. According to the rectification device for the methylal reaction, the liquid distributing pipe and the spray nozzles are arranged, so that a methanol liquid can be uniformly distributed in the rectification tower, further, the spray nozzles have a dispersing function, and accordingly, methyl alcohol and methanal can be sufficiently contacted.
Description
Technical field
The utility model relates to a kind of chemical industry equipment, relates to specifically a kind of dimethoxym ethane reaction and rectification device.
Background technology
The rectifier unit of preparing at present dimethoxym ethane, its raw material mostly is from tower reactor is disposable and adds, although this feed way simple and fast; But exist between raw material, cannot fully effectively contact, and time of contact is short, the concentration of target product is low.
The patent that notification number is CN200955036Y for this reason provides a kind of new technical scheme, specific as follows: two charging apertures are set on rectifying column, top is high boiling material inlet (formaldehyde charging aperture), and bottom is lower boiling material inlet (methanol feeding mouth); This kind of its advantage of feed way be, when two kinds of raw materials add in rectifying column, the methyl alcohol vaporization of being heated moves upward, and formaldehyde is still liquid and moves downward, therefore two kinds of material counter current contacting have promoted fully carrying out of reaction.
But still there is defect in above-mentioned patent, although both energy counter current contacting, but the characteristic due to gas, methyl alcohol after vaporization can move to each corner of rectifying column soon, formaldehyde as liquid distributes more in a side of charging aperture, because the bore of rectifying column is generally larger, cause in rectifying column less away from its content of formaldehyde of portion of formaldehyde charging aperture, so the methyl alcohol of this portion its can not be fully and formaldehyde haptoreaction; Therefore can cause each contact inequality in rectifying column, a part of methyl alcohol can not effectively participate in reaction, causes the invalid loss of methyl alcohol, has improved the production cost of enterprise.
Utility model content
The utility model is for above-mentioned defect, and it is a kind of simple in structure that object is to provide, and can make formaldehyde liquid uniform in rectifying column, thus the dimethoxym ethane reaction and rectification device that methyl alcohol is effectively fully contacted with formaldehyde.
The technical solution adopted in the utility model is for this reason: the utility model includes rectifying column, on described rectifying column, be provided with two charging apertures, be respectively the formaldehyde charging aperture that is arranged on top and the methanol feeding mouth that is arranged on bottom, described formaldehyde charging aperture extends a separating tube in rectifying column, and separating tube bottom is equipped with spray nozzle some and that separating tube is communicated with.
Described formaldehyde charging aperture is two, is symmetricly set on rectifying column both sides, and a side of each formaldehyde charging aperture arranges respectively the separating tube corresponding with it and spray nozzle.
Described formaldehyde charging aperture, methanol feeding mouth are all arranged on below the rectifying section of rectifying column.
The utility model has the advantages that: 1) the utility model arranges separating tube and spray nozzle, make like this formalin physical efficiency be distributed in rectifying column, and spray nozzle itself also has peptizaiton, make like this methyl alcohol can fully contact with formaldehyde;
2) consider that rectifying column bore is larger, formaldehyde charging aperture of the present utility model can be arranged to two, and formaldehyde can, respectively from two throat-fed, further have been guaranteed formaldehyde being uniformly distributed in rectifying column like this.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is that rectifying column, 2 is that formaldehyde charging aperture, 3 is that methanol feeding mouth, 4 is that separating tube, 5 is spray nozzle.
The specific embodiment
The utility model includes rectifying column 1, on described rectifying column 1, be provided with two charging apertures, be respectively the formaldehyde charging aperture 2 that is arranged on top and the methanol feeding mouth 3 that is arranged on bottom, described formaldehyde charging aperture 2 extends a separating tube 4 in rectifying column 1, and separating tube 4 bottoms are equipped with spray nozzle 5 some and that separating tube 4 is communicated with.
Described formaldehyde charging aperture 2 is two, is symmetricly set on rectifying column 1 both sides, and a side of each formaldehyde charging aperture 2 arranges respectively the separating tube corresponding with it 4 and spray nozzle 5.
Described formaldehyde charging aperture 2, methanol feeding mouth 3 are all arranged on below the rectifying section of rectifying column 1.
It should be noted that, formaldehyde charging aperture 2 of the present utility model can be set to more than three or three, and this is determined by concrete production actual conditions.
Other structures of the utility model rectifying column, such as the setting of heater is, the setting of agitating device can be with reference to the explanation of CN200955036Y, at this, is not just described.
