Abstract

An improved electrolytic cell, its method and system configured for simple and rapid troubleshooting, removal and replacement of the cell or a component of the cell during service and maintenance procedures is disclosed. The electrolytic cell ( 12 ) is includes a host manifold ( 27 ) housing a degassing chamber ( 125 ) and various flow paths for routing liquid and gases into and out of a guest device ( 33 ) and the host manifold ( 27 ). The host manifold ( 27 ) is connected to input sources and output collections. The guest device ( 33 ) generally houses an anode chamber ( 104 ), a cathode chamber ( 112 ), and a brine chamber or reservoir ( 108 ) that serves as a source of anions and cations for the anode and cathode chambers. The guest device ( 33 ) is separable from the host manifold ( 27 ) to repair, maintain and/or replace the cell.

First claim

What is claimed is:

1. An electrolytic cell configured for simple and rapid cell troubleshooting, removal and replacement during service and maintenance procedures comprising:
a distribution manifold having a host interface and a flow path originating at an inlet and terminating at an outlet;
a cathode section having a flow path adapted for carrying cations and a guest interface with an exchange connection configured for removably seating at the host interface;
an anode section having a flow path adapted for carrying anions and a guest interface with an exchange connection configured for removably seating at the host interface; and
an electrode associated with respective anode and cathode sections;
a degassing chamber within the distribution manifold and in fluid communication with the flow path of the cathode section at the host interface and the flow path of the anode section at the host interface;
said cathode and anode sections positioned adjacent one another with inlets and outlets disposed on substantially the same side of the distribution manifold with one of the anode or cathode sections at least partially within the other;
wherein the cathode, anode and electrolyte sections are removably staged at the host interface by one or more connectors, said connectors comprising actuable securing members that can removably attach the sections to the host interface to allow for access to the sections for simple and rapid cell troubleshooting, removal and replacement during service and maintenance procedures thereof.

2. The electrolytic cell of claim 1 further comprising an electrolyte section having a flow path adapted for carrying an electrolyte and a guest interface with an exchange connection configured for removably seating at the host interface.

3. The electrolytic cell of claim 2 further comprising an exchange membrane removably received between cathode and anode flow paths and the electrolyte flow path.

4. The electrolytic cell of claim 1 wherein the flow path originating at the inlet in the distribution manifold is in plumbed connection to an electrolyte source.

5. The electrolytic cell of claim 1 wherein the degassing chamber has an inlet and an outlet, the inlet being positioned above the outlet so as to gravity feed a catholyte from the cathode section to the anode section.

6. The electrolytic cell of claim 2 wherein the flow path originating at the inlet in the distribution manifold is in plumbed connection to a water source.

7. The electrolytic cell of claim 1 wherein the actuable securing members comprise:
a. toggle clamps;
b. latches;
c. pins;
d. bands;
e. straps; or
f. bolts.

8. The electrolytic cell of claim 1 wherein the cathode and anode exchange connections comprise an inlet and outlet to the respective cathode and anode flow paths.

9. The electrolytic cell of claim 1 wherein the cathode and anode exchange connections comprise an electrical connection to the respective cathode and anode electrodes.

10. The electrolytic cell of claim 1 wherein the cathode and anode exchange connections comprise alignment points to align the respective cathode and anode guest interfaces with the host interface.

11. A system configured for simple and rapid troubleshooting, removal and replacement of an electrolytic cell during service and maintenance procedures comprising:
a. a distribution manifold having a host interface and a flow path originating at an inlet and terminating at an outlet at the host interface; and
b. a guest device removably connected at a face of the host interface comprising:
i. a guest interface with an exchange connection configured for removably seating at the host interface of the distribution manifold;
ii. an electrolytic cell having a cathode section with a flow path adapted for carrying cations and an anode section having a flow path adapted for carrying anions in fluid communication with the guest; and
iii. the electrolytic cell in fluid communication with the exchange connection at the guest interface
iv. said cathode and anode sections positioned adjacent one another with inlets and outlets disposed on substantially the same side of the distribution manifold with one of the anode or cathode sections at least partially within the other;

c. a degassing chamber within the distribution manifold and in fluid communication with the flow path of the cathode section at the host interface and the flow path of the anode section at the host interface; and

wherein the guest device is removably staged at the host interface by one or more connectors, said connectors comprising actuable securing members that can removably attach the guest device to the host interface to allow for access to the sections for simple and rapid cell troubleshooting, removal and replacement during service and maintenance procedures thereof.
