Aluda’s SM head

[Aluda]

Question for the connoisseurs. I don't speak English, so sorry for the construction of the sentence. What should I call the device for controlling the selection by surface area. I propose to call it as SM. In the proposed design of the refrigerator. Condensation flows down the walls. The proposed device, the selection regulator, allows you to redistribute the volume according to the position of the control damper, in proportion to the movement of its position. And I found a similar design, someone tried to develop the idea of ​​​​a selection regulator with the ability to redistribute the selection by changing the position of the refrigerator.

Interested in this design. Having many advantages over LM, VM, CM. I tried to depict as a development of the surface of a tubular refrigerator. Provided that the condensate, flowing down the walls of a sufficiently large diameter of the condenser beam. Moves vertically under the influence of gravity. The surface of the condenser has no condensation concentrators. Or roughness.,surface must not have condensation priority.

I drew a little, it turned out to make a damper from cutting a silicone hose or tube. At the same time, the mechanical drive of the damper remained unresolved.

As a result, I worked a little and got such a selection and return regulator.

[Aluda]

This is my finished working capacitor.

A similar design can be made with two electro valves, or one distributive, three way.

Question to the old people, why is this solution not on the Internet? I have not tried it in my work yet, since I only have a boiler and a condenser, I do not have a distillation column.

I believe you are describing a liquid management system.

The last picture looks like a offset liquid management with a valve in the reflux return:

called a "Nixon-Stone" by some people.

Your other images look like a concentric liquid management with the valves internal to the column

[Aluda]

If you remove the container before the overflow of the return to the column begins, if you remove the container before the solenoid valve. This volume of container will always be, it matters. Until this volume is filled, the overflow of the gate will not begin. I think that at certain low heating powers there will be a bad influence on the dosing of the operating mode of the column. You are wrong Elbono, this is not Nixon Stone. This is different. I regulate the area ratio of steam condensation. The ratio of the surface of the gate to the column and the area of ​​selection. I drew Nixon Stone with two valves or one changeover (three holes).
If you reduce the heating power, the volume of condensate may be less than the volume of the accumulator before the return overflow. In this mode, regardless of the duration of the on state of the solenoid valve. All condensate will go to the selection.

Looks like reversed LM

[Aluda]

Proportional, analog selection controller.

That's a nice build. I'm suspicious of its performance but the workmanship looks exceptional.

[Aluda]

[Aluda]

Performance will be in question. I have just such a steam boiler from a beer keg of 30 liters.

I'm thinking of switching to steam extraction in the center of the lid.

Instead of "performance" perhaps I should have said "throughput." With such a small diameter output tube on your heat exchanger/condenser, I suspect your output will sputter without an atmospheric vent to allow smooth, consistent drainage.

[Wildcats]

It that your boiler?

[Aluda]

My kettle heater is 2kVt. I have a long pipe 40 mm for a distillation column. The refrigerator has been tested and can handle 2kW of heat. For cleaning in the rectification mode, I think to try. I'm interested in the idea of regulating the selection, how much you turn the damper%, so much you will select. I wonder why the idea with a movable damper, a damper with a capacitor area divider is not on the Internet. As an advantage, there is no change in the total area of the refrigerator, depending on the selection. There is no influence of parasitic volume in front of the solenoid valve. Some advantages, if not the complexity of the mechanical design. Please excuse my English, I was born
to Kavkaz, Chechnya, the city of Grozny. Now I live in Kaliningrad.
The narrowest point for the passage of steam in the selection device with a diameter of 22 mm. The area of constriction in the selection device is 3.8 square centimeters. The length of the constriction is less than 20 mm.

Maybe it is .
Have you seen this topic YHB . He did some very clever stuff here.

I love it when stuff like this gets linked. I had not seen this before. Thanks.

In this design, in the extreme positions of the damper, the condenser area is half as much, if the damper in the middle has a maximum condenser area. If I close the condenser with a damper, where there is no connection with atmospheric air, the pressure there will depend on temperature. It will either suck in air, insulating the surface of the refrigerator, or there will be a very low pressure, it will suck in steam. In its design, initially there is no proportionality of selection, proportionality of the movement of the damper.
From a theoretical position in the design of the LM, if a solenoid valve is used without the approach of the tube and the volume of liquid above the valve. There is nothing better. But structurally, between the valve and the place of overflow into the column, there is always a parasitic volume of the pipeline. In what modes it will not give proportionality. Proportionality of switching-on time, volume. At the beginning with a small selection. The pipeline is always full.

I’m really finding it hard to understand your design . Google translate is not helping as any reference to Condensers sometimes appears as a Capacitor or a Refrigerator.

I thought you had a variable vapour proportioning valve . Now you talk about a solenoid valve .

Can you draw a diagram of your still ? It might help us understand what you are doing .

Right.... I was at a complete loss... Thought maybe I just wasn't smart enough to get it.... Glad I'm not the only one. Makes me feel better

Makes three of us...........this thread started out as a thread to help newbies understand the difference between certain types of stills.
It has now turned into a thread to confuse hell out of them.

[Aluda]

I'm trying to draw in isometric. The condensate dew flows down. And I regulate the surface area from which the condensate goes to the selection. The rest of the condensate is returned to the distillation column. Regardless of the performance, the amount of steam, regardless of the temperature of the cooling water, the ratio of the volume of return and selection does not change. The ratio is set by the position of the movable damper. I'm done? I got it right. My volume of the refrigerator does not change, from the relationship of selection and return. This is a different design. Selection area regulator.
Let's call him SM.

[Sporacle]

Am I missing something? all I can see is a Boka with the base of the condensor acting as the slant plates and the selector acting as the needle valve.
Having said that I do confuse easily

[Yummyrum]

Think you got it right Sporacle.

It’s actually a clever idea .It does rely heavily on a very uniform and evenly distributed fall of reflux rain .That is the bit that I wonder most about as from my observation's , reflux generally tends to form and fall off certain points and in narrow streams . Or in the case of my plated still , off the tubes in the deflag . Having said that , I get 7 streams , 6 off the outer pipes and one off the centre . Ignoring the centre one , that would still only provide 1:5 ,2:4 , 3:3 , 4:2 , 5:1 , and of coarse, 0 and 100% RR .
Adding more reflux tubes or dribble points would increase the number of RR possibilities .

So this is where Aludas reflux fall pattern is confusing me . Get that right and its a great idea . I still think it is a Liquid management still as that is what is being proportioned . However, I agree with Aluda that reflux ratio is independent of power and therefore vapour production .

I think it deserves more experimenting . Not the easiest still head design to make , but certainly full of possibilities and potential .

[Yummyrum]

So this is where Aludas reflux fall pattern is confusing me . Get that right and its a great idea . I still thing it is a Liquid management still as that is what is being proportioned .

Apologies , I just re-read . It assumes condensation falls down wall of condenser . It should work great … iff’n that occurs .

It also allow you to adjust the volume of collection cup (LM). How it will translate to product collection rate I do not understand, maybe if you have a large take-off port? But changes in the volume of the cup may change the product.

The build is different enough from the normal "types of stills" that it's posted in.
This needs a separate place so it doesn't get lost and we can ask Aluda questions about it.

Exactly Shady .
Thats why I split it off the LM/VM/CM topic and made it a seperate topic . I’ve stuck it in Research and theory section , but maybe it should be in a build section . Any suggestions welcome .

[Aluda]

The weak point of my design, the small diameter, is the small value of the height and width of the capacitor surface. We all watched how a drop of rain flows down the glass, how condensate flows down the glass in winter. The path along which a drop of condensate flows is not always to the bottom. It depends on the strength of wetting of the cooling surface of the condenser. Depends on the size, weight of the liquid droplet adhering to the surface of the capacitor. Depends on the presence of essential oil on the surface of the capacitor, the roughness of the surface, the electric field as in a thunderstorm in the rain. Thank you for your support, thank you for your attention.
Any suggestions welcome .

Perhaps you could move the discussion of your design to a separate thread since this thread started as a discussion of LM, VM, and CM.
It's also a bit confusing when the subject of this thread is changed from the original to "Aluda's SM head". If you have your own thread then it's less likely the subject will get changed and anyone interested in the discussion or searching will be more likely to see it.

Think I’ve fixed the point of confusion Boilermaker. When we split topics , the “Re: Subject” gets moved as well . So we then have to edit every post and change it otherwise each new post just copies the Re: subject from the previous one .

[BoilerMaker]

I hadn't noticed I was replying to the thread already split off. I think it's more useful this way, thanks.

[drmiller100]

It won't work.

Someone please post the magic graph.

You have liquid running down the walls and steam running up the center. To distill is to condense and re vaporize over and over.

Otherwise you have a pot still.

I tried various versions of this.

I did make a 1000 watt pot still that used half inch diameter copper pipe at about a 20 degree angle to horizontal with reflux at the top. 45 inches of the almost horizontal column would happily make azeo from. 8 percent. The gimmick was the copper would transfer the heat energy of vapor going up to the liquid stream going down.
