Description
Technical field
The utility model relates to methanol recovery device, is specifically related to a kind of methyl alcohol reboiler.
Technical field
At present, produce dimethyl ether generally adopt methanol gas phase dehydration method technique prepare, this be also current industrial making dimethyl ether the most maturation a kind of technique.In the process of producing dimethyl ether, by once, the gas-phase dehydration of twice, be difficult to methyl alcohol fully and completely to resolve into dimethyl ether and water, still have a large amount of methyl alcohol in residual waste liquid, if directly discard, not only just cause very large wastage of material, also contaminated environment.
Utility model content
For above-mentioned deficiency of the prior art, it is little and can to the methyl alcohol methyl alcohol reboiler that extract in residual solution when producing dimethyl ether that the utility model provides a kind of volume.
In order to reach foregoing invention object, the technical solution adopted in the utility model is:
There is provided a kind of methyl alcohol reboiler, it comprises tank body and the heat exchange structure in tank body that spirals twist; The heat exchange pipeline that heat exchange structure is at least increased progressively gradually by four diameters forms; Diameter heat exchange pipeline is from small to large arranged to edge side by the central side of tank body respectively; Every root heat exchange pipeline two ends are all threaded connection mode and are fixedly connected with heat exchanger tube escape pipe with the heat exchanger tube air inlet pipe be arranged on tank body; Every root heat exchange pipeline is all enclosed with a diameter outward and is greater than heat exchange pipeline diameter, flow to the arc of tank base for residual solution, and every root arc is fixedly connected with the waste liquid feed tube being arranged on tank body top directly over it by screw thread.
The beneficial effects of the utility model are: residual solution when producing dimethyl ether enters arc by four waste liquid feed tubes at tank body top, while flow to tank base along arc, limit and heat exchange pipeline carry out heat exchange; Because the boiling point (64.7) of methyl alcohol is lower, methyl alcohol is separated from methanol steam mouth carrying out the process of circulation just can vaporize fast; The methyl alcohol separated can be added in the raw material producing dimethyl ether again, reduces the waste of raw material greatly, reduces unnecessary energy waste.

Detailed description of the invention
Below detailed description of the invention of the present utility model is described; so that those skilled in the art understand the utility model; but should be clear; the utility model is not limited to the scope of detailed description of the invention; to those skilled in the art; as long as various change to limit and in the spirit and scope of the present utility model determined, these changes are apparent, and all innovation and creation utilizing the utility model to conceive are all at the row of protection in appended claim.
The sectional view of methyl alcohol reboiler is shown with reference to figure 1 and Fig. 2, Fig. 1; Fig. 2 shows the top view of methyl alcohol reboiler; As depicted in figs. 1 and 2, this methyl alcohol reboiler heat exchange structure of comprising tank body 13 and spiraling twist in tank body 13.
Inside its spirality, also there is a large amount of spaces because heat exchange pipeline 11 spirals after spirality, in order to reduce the volume of reboiler, the less heat exchange pipeline of spirality 11 can be installed in the spiral heat exchange tube road 11 that diameter is larger.So the heat exchange pipeline 11 that the heat exchange structure of this programme is at least increased progressively gradually by four diameters forms.
During production, in order to reduce the degree-of-difficulty factor that heat exchange pipeline 11 is installed, the heat exchange pipeline 11 that preferred heat exchange structure is increased progressively gradually by four diameters forms.
Diameter heat exchange pipeline 11 is from small to large arranged to edge side by the central side of tank body 13 respectively, and the heat exchange pipeline 11 that namely diameter is little is positioned at inside the spirality of diameter large heat exchange pipeline 11 formation all the time.
For the ease of the installation of heat exchange pipeline 11, heat exchange pipeline 11 is arranged with heat exchanger tube air inlet pipe 15 and heat exchanger tube escape pipe 16 split, when assembling, every root heat exchange pipeline 11 two ends are all threaded connection mode and are fixedly connected with heat exchanger tube escape pipe 16 with the heat exchanger tube air inlet pipe 15 be arranged on tank body 13.
Every root heat exchange pipeline 11 is outer to be all enclosed with a diameter and to be greater than heat exchange pipeline 11 diameter, to flow to arc 12 bottom tank body 13 for residual solution, after arranging like this, after residual solution when producing dimethyl ether enters arc 12 by four waste liquid feed tubes 17 at tank body 13 top, can limit along arc 12 to tank body 13 flows, limit and heat exchange pipeline 11 carry out heat exchange.
Methyl alcohol is separated from methanol steam mouth 18 carrying out the process of circulation just can vaporize fast; The methyl alcohol separated can be added in the raw material producing dimethyl ether again, reduces the waste of raw material greatly, reduces unnecessary energy waste.
For the ease of the installation of arc 12, every root arc 12 is also that split is arranged with each waste liquid feed tube 17, and during assembling, every root arc 12 is fixedly connected with the waste liquid feed tube 17 being arranged on tank body 13 top by screw thread.
Be arranged on the outside of heat exchange pipeline 11 for the ease of arc 12 rapidly, the A/F of arc 12 is arranged to the diameter being more than or equal to heat exchange pipeline 11; During production, preferred arc 12 A/F is greater than the diameter of heat exchange pipeline 11.
Because the heat exchange pipeline 11 that diameter is little is positioned at inside the spirality of diameter large heat exchange pipeline 11 formation all the time, when installing heat exchange pipeline 11, first the less heat exchange pipeline of diameter 11 is installed, when being installed to the heat exchange pipeline 11 of largest diameter, it is narrow and small that space in tank body 13 has become very, for the ease of the installation of the heat exchange pipeline 11 of largest diameter, the distance between the heat exchange pipeline 11 and tank body 13 wall of tank body 13 edge side is at least more than or equal to 10cm.
When there is multiple spiral in heat exchange pipeline 11 in tank body 13, its total quality is just larger, support force only by heat exchanger tube air inlet pipe 15 and heat exchanger tube escape pipe 16 place is difficult to the stability ensureing heat exchange pipeline 11, so be fixed on tank wall by some connecting rods away from heat exchanger tube air inlet pipe 15 side at every root heat exchange pipeline 11.In like manner the stability of arc 12 is also like this, so every root arc 12 is also fixed on tank wall by some connecting rods.
Reboiler in use for some time; on tank wall, in heat exchange pipeline 11 and arc 12 inside all can remain a large amount of dirts; in order to avoid dirt affects the normal heat exchange of residual solution and heat exchange pipeline inner vapor, tank wall is installed with some ultrasonic generators 14 for cleaning tank body 13, heat exchange pipeline 11 and arc 12.
