Description

Technical Field

[0001] This utility model relates to the field of ethanol distillation technology, and more specifically, to a device for separating higher alcohols from water. Background Technology

[0002] Higher alcohol and water separation equipment has always been an important separation device in the chemical industry. High separation efficiency can effectively reduce energy consumption and improve product yield, playing a very important role in the entire process. With the continuous advancement of technology, the requirements for the precision of alcohol-water separation in chemical production are becoming increasingly stringent, as are the requirements for energy consumption. In addition, for ethanol production, alcohol-water separation technology affects the ethanol recovery rate and the water content of the separated higher alcohols.

[0003] Current oil-water separation equipment primarily relies on the density differences between different liquids, utilizing the principle of gravity sedimentation or other physical and chemical methods to achieve the stratification and separation of oil and water. The equipment typically incorporates separation elements such as diffusion cones, filters, and multi-stage filtration systems to remove impurities and moisture. Oil-water separation equipment generally includes key components such as horizontal separation tanks, inlet pipes, outlet pipes, and multi-stage coalescing systems. It is mostly used in petrochemical oil-water separation where the density difference between oil and water is greater than that between alcohol and water. If similar equipment is used for alcohol-water separation, the separation efficiency is poor. To achieve higher separation requirements, longer residence times and larger equipment volumes are needed.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this utility model, and therefore may include information that does not constitute prior art known to those skilled in the art.

Through the structural design of the coalescence mechanism, microchannel mechanism, and fusel oil mixture distribution pipe 4 inside the horizontal cylinder 1, the fusel oil mixture is evenly distributed in the distribution zone 5. As the height of the fusel oil mixture in the distribution zone 5 increases, it flows downstream through the coalescer 21. The higher alcohol phase collides and adheres within the coalescer 21, accelerating the efficient coalescence, rapid ascent, aggregation, and separation of fine oil droplets (higher alcohol phase) within the coalescer 21, thereby improving the separation efficiency of higher alcohols and water. After the alcohol-water separation is promoted by the coalescer 21, the mixture rises into the microchannel separator 31. Through the microchannel separator 31, the mixing... The disturbance of droplets during the liquid flow process is conducive to droplet coalescence. After further alcohol-water separation, the aqueous phase gradually settles into the aqueous phase zone 6 and is discharged outside the horizontal cylinder 1 through the aqueous phase outlet 61. The fusel oil fraction of the higher alcohol continues to rise and enters the oil phase zone 7 from the top of the microchannel separator 31. It is discharged outside the horizontal cylinder 1 through the oil phase outlet 71. The internal space area of ​​the horizontal cylinder 1 can be greatly utilized. The coalescer 21 and the microchannel separator 31 promote the continuous renewal of the interface between the light and heavy phases and continuous coalescence, thereby separating according to the density difference. The separation efficiency is high and it can be used for atmospheric pressure separation as well as pressurized separation.

[0042] As a preferred embodiment of this utility model, a fusel oil dilution and mixing mechanism is connected to the inlet end of the fusel oil mixture distribution pipe 4;

[0043] The fusel oil dilution and mixing mechanism includes a pipe mixer 81 connected to the fusel oil mixture distribution pipe 4, a fusel oil delivery pipe 82 located at the inlet end of the pipe mixer 81, and a water supply pipe 83 located at the top of the inlet end of the pipe mixer 81.

[0044] As a preferred embodiment of this utility model, the fusel oil mixture distribution pipe 4 and the pipeline mixer 81 are connected by a connecting pipe 84.

[0045] Specifically, in order to meet the process conditions of separating higher alcohols from ethanol and water, a fusel oil dilution and mixing mechanism is connected to the inlet end of the fusel oil mixture distribution pipe 4. The fusel oil fraction is sent from the fusel oil delivery pipe 82 into the pipeline mixer 81, and the demineralized water is sent from the water supply pipe 83 into the pipeline mixer 81. The mixture is mixed in the pipeline mixer 81 to reduce the ethanol concentration to 10% to 13% and then sent into the fusel oil mixture distribution pipe 4 through the connecting pipe 84.

[0046] As a preferred embodiment of the present invention, the fusel oil mixture distribution pipe 4 includes a main pipe 42 and at least two branch pipes 43 connected at one end to the outlet of the main pipe 42; wherein, the inlet end of the main pipe 42 is the inlet end of the fusel oil mixture distribution pipe 4; the other end of each branch pipe 43 is sealed; and each branch pipe 43 is provided with distribution holes 41 evenly distributed on its body.

[0047] Specifically, by setting multiple branch pipes 43, each branch pipe 43 is provided with several liquid distribution holes 41 evenly distributed on its body, the liquid distribution can be more uniform. The liquid distribution holes 41 are preferably located at the bottom of the branch pipe 43, which can better distribute the liquid evenly and is more conducive to the separation between the two liquids.

[0048] As a preferred embodiment of this utility model, the coalescer 21 is composed of several layers of coalescing packing.

[0049] Specifically, the coalescing packing layer is preferably, but not limited to, the coalescing TP plate packing layer, 304 oil-water coalescing packing layer, etc., and this utility model does not make any special limitation in this regard.

[0050] As a preferred embodiment of the present invention, the microchannel separator 31 is composed of a first semi-circular corrugated plate 311 and a second semi-circular corrugated plate 312 that is mirror image of the first semi-circular corrugated plate 311 stacked together.

[0051] Specifically, such as Figures 5 to 8 As shown, the microchannel separator 31 is composed of several first semi-circular corrugated plates 311 and second semi-circular corrugated plates 312 that are mirror images of the first semi-circular corrugated plates 311. A tubular chain formed by stacking the first semi-circular corrugated plates 311 and their mirror images 312 is then stacked at a certain angle to form the microchannel separator 31. The stacked microchannel separator 31 forms multiple circular channels inside. When the liquid flows from bottom to top, each channel is independent of the others, reducing disturbance in the liquid flow and allowing for thorough separation of the two phases.

[0052] Microchannels formed by spot-welding a certain number of concave and convex inclined plates with ribs at fixed intervals can increase the coalescence area, improve throughput and separation efficiency, and enhance the interaction between the plates and droplets, thereby reducing the disturbance to droplets during liquid flow and promoting droplet coalescence. Due to the continuous flow of the upper film on the inclined plates, the interface surface between the film and the diffusion system is constantly renewed, reducing the opportunity for surface-active substances to aggregate. Therefore, the influence of surface-active substances on droplet coalescence is reduced.

[0055] As a preferred embodiment of this utility model, a vortex breaker 72 is provided at the oil phase outlet 71.

[0056] Specifically, by setting the vortex breaker 72, the outflowing oil phase can be made more stable.

[0057] As a preferred embodiment of this utility model, a first interface gauge port 63 is provided on the horizontal cylinder 1 located in the aqueous phase zone 6; a first interface gauge is provided in the first interface gauge port 63; and / or, a thermometer port 51 is provided on the horizontal cylinder 1 located in the liquid distribution zone 5; a thermometer is provided in the thermometer port 51; a second interface gauge port 73 is provided on the horizontal cylinder 1 located in the oil phase zone 7; a second interface gauge is provided in the second interface gauge port 73.

The interface gauge port is used to house an interface gauge to measure the interface position between oil and water in a liquid; a density meter can also be added to enhance operation and control.

[0060] As can be seen from the above specific embodiments, the advanced alcohol and water separation device provided by this utility model, through the structural design of the coalescence mechanism, microchannel mechanism, and fusel alcohol mixture distribution pipe inside the horizontal cylindrical body, allows the fusel alcohol mixture to be evenly distributed in the distribution area through the fusel alcohol mixture distribution pipe. As the height of the fusel alcohol mixture in the distribution area increases, the fusel alcohol mixture flows downstream through the coalescer. The advanced alcohol phase collides and adheres in the coalescer, accelerating the efficient coalescence, rapid ascent, aggregation, and separation of fine oil droplets (advanced alcohol phase) in the coalescer, thereby improving the efficiency of advanced alcohol and water separation. After the alcohol-water separation is promoted by the coalescer, the mixture rises into the microchannel for separation. The device, through a microchannel separator, reduces the disturbance to droplets during the liquid flow of the mixture, which is conducive to droplet coalescence. After further alcohol-water separation, the aqueous phase gradually settles into the aqueous phase zone and is discharged outside the horizontal cylinder through the aqueous phase outlet. The fusel oil fraction of higher alcohols continues to rise and enters the oil phase zone from the top of the microchannel separator, and is discharged outside the horizontal cylinder through the oil phase outlet. It can make great use of the internal space area of ​​the horizontal cylinder, and the coalescer and microchannel separator promote the continuous renewal of the interface between light and heavy phases and continuous coalescence, thereby separating according to density difference. The separation efficiency is high and it can be used for atmospheric pressure separation as well as pressurized separation.
