Hi All, I have a new info to share today and I decided to go with a sml story fr the people who might nt be aware of our journey with this system...
A little Background
It has been more than a year and a half that I have been using this method for my planted setups. Initially it looked great when we were moving over from sugar yeast method and in the excitement we ignored the fact that the stock design can be very troublesome on occasions. Further down the time line, I was thinking to update the reactor design to get rid of the 'Reaction Delay' issue due to which the pressure used to rise up abruptly.
The design was ready and the only remaining part was to implement and test if the new design addresses the issue in the expected manner. But, as usual i kept on procrastinating and one fine day due to the abrupt pressure hike one of my 5 reactors blasted at 100+psi at a distance of 6-7inches from my face and wounded my cheek such a way that the scar will remain prominent on my face for the rest of my life. And I am yet to get married...
It took me arnd three weeks to get healed...and then I finally went on to update the design. Below I am sharing both the designs, the one that blasted and the modified one. Before that, let me share my experience with the new updated design.
I am using the new design for more than 6 mnths now and havnt yet noticed any abrupt pressure hikes...I have five of these systems running at my place and i helped some other friend to make these too...so total systems running with this update shld be arnd 15 or more and no complaints so far about abrupt pressure hikes....
Now the designs-
Design Update Description-
A T join and two check valves has been added in the soda bottle.
T join- separates the input(citric acid) and output(CO2) flow routes. both these routes are made to work one way by the check valves. this is required to attain a stable and uniform reactor.
In the older version, the T join nd the chk valves were not present and the citric acid used to drip on the soda. with time when the liquid level used to rise up, it delayed the reaction time as the fluid medium was working as a separator between the soda and the citric acid dropping at the surface of the liquid. because of the delay in the reaction, more citric acid used to get poured in before the reaction started and once the reaction started, the pressure used to go v high due to extra amount of citric acid poured in.
To overcome the reaction delay, it is required that the citric acid reacts to the soda as soon as it comes out of the pipe. Hence, the pipe was to be elongated till the bottles's floor to stay in touch with the soda. but the issue here is when citric acid reacts to the soda, co2 will b generated and pressure in the soda bottle will become more than the pressure in the citric bottle and due to this, soda will be pushed through the pipe to the citric acid bottle and then the soda will react in the citric bottle creating co2 and hence rise in pressure which will again push the citric acid to the soda chamber and again react there forming co2, thn pressure rise, thn soda flows to citric bottle and so on....it will become a chain reaction.
So, a check valve was put in the pipe to avoid the back flow of soda to the citric acid bottle. but then we need the pressure to be in equilibrium across the two bottles or else the reactor's pressure will keep dropping. So some of the co2 needs to be flowed back to the citric acid chamber, hence a T join was added. Aftr this, using only T join will make the system bak to the older model as the critic acid will then again drop through the open end(least resistance path) of the T join. So a chk valve was added so that the route will only open when co2 push opens the check valve.
So, for both the existing and the people who want to make this reactor, please please please pay attention while putting the check valves. the check valves need to open in the direction of the arrows provided in the pic.
And last of all, please forgive me if the above things sound confusing, as I really suck when it comes to teaching.
So feel free to point out the portions wherever sounds confusing. I will try my best to simplify it.
Thank you ALL for bearing with me...
