The utility model discloses can both take away the heat that the electrolysis process produced through the raw water, can carry out effective electrolysis with the chlorion in the raw water again, increase the effective chlorine concentration of electrolysis effluent.
Description
Technical Field
The utility model relates to the technical field of electrolytic devices, in particular to a double-layer diaphragm-free electrolytic device.
Background
The slightly acidic electrolyzed water is prepared by adding proper amount of dilute hydrochloric acid with low concentration and/or sodium chloride aqueous solution into a diaphragm-free electrolytic cell, and generating chlorine and H at the anode by electrolysis+，H+Dissolving in water to make waterThe chlorine gas reacts with water to generate hydrochloric acid and hypochlorous acid (HClO) with acidic pH value of 5.0-6.5.
During the electrolytic reaction, part of the electric energy is converted into heat energy, so that the temperature of the liquid in the electrolytic bath is increased. The study shows that the temperature in the diaphragm-free electrolytic cell can reach 75 ℃ at most. The electrode is in a high-acidity and high-temperature environment for a long time, so that the falling of the surface coating of the electrode is accelerated, and the service life of the electrode is shortened.
Therefore, the utility model adopts the design of the double-layer electrolytic tank, which not only takes away the heat generated in the electrolytic process through the raw water, but also electrolyzes the chloride ions in the raw water, thereby increasing the effective chlorine concentration of the electrolyzed water.
SUMMERY OF THE UTILITY MODEL
In view of the deficiency of the background art, the utility model provides a can both take away the heat that the electrolysis process produced through the raw water, can carry out effective electrolysis, increase the double-deck no diaphragm type electrolytic device of the effective chlorine concentration who electrolyzes the effluent with the chloride ion in the raw water again.
For solving the technical problem, the utility model provides a following technical scheme:
double-deck no diaphragm formula electrolytic device, including the shell body, be equipped with water inlet and delivery port on the shell body, be equipped with interior casing in the shell body, be connected with on the interior casing and stretch out the outside feed liquor pipe of shell body and the check valve that is used for exporting the gas-liquid, the internally mounted of interior casing has the electrode slice that a plurality of ranges set up, interior casing with interval in proper order has net negative pole and net positive pole between the shell body.
The liquid inlet pipe is connected to the bottom of the inner shell.
The check valve is installed on the top of the inner housing.
And the electrode plates are horizontally arranged on the inner shell and are uniformly arranged at intervals.
The electrode plate is made of a titanium-based platinized iridium electrode.
The grid anode and the grid cathode are made of titanium-based platinized electrodes.
Compared with the prior art, the utility model beneficial effect who has is: the heat generated in the electrolysis process can be taken away by raw water, and the chloride ions in the raw water can be effectively electrolyzed to increase the effective chlorine concentration of electrolyzed water.

The utility model discloses there is following figure:
fig. 1 is a schematic cross-sectional view of the present invention.
Detailed Description
As shown in the figure, the double-layer diaphragm-free type electrolytic device provided by the embodiment comprises an outer shell 1, the outer shell 1 is provided with a water inlet 11 and a water outlet 12, the outer shell 1 is internally provided with an inner shell 2, the inner shell 2 is connected with a liquid inlet pipe 21 extending out of the outer shell 1 and a one-way valve 3 for outputting gas and liquid, a plurality of electrode plates 4 arranged in a row are arranged in the inner shell 2, a grid cathode 5 and a grid anode 6 are sequentially arranged between the inner shell 2 and the outer shell 1 at intervals, in the present embodiment, the outer casing 1 and the inner casing 1 are both hollow cylindrical in shape, the network cathode 5 and the network anode 6 are both arranged in a ring shape, and a gap is reserved between the network cathode 5 and the network anode 6 and the top surface of the outer shell, and a gap is also reserved between the top surface of the inner shell 2 and the top surface of the outer shell 1.
In this embodiment, the liquid inlet pipe 21 is connected to the bottom of the inner case 2.
In the present embodiment, the check valve 3 is installed on the top of the inner case 2.
In this embodiment, a plurality of electrode plates 4 are horizontally installed on the inner housing 2 and are uniformly spaced.
In this embodiment, the electrode sheet 4 is made of a titanium-based platinum-iridium-plated electrode.
In this embodiment, the material of the network cathode 5 and the network anode 6 is titanium-based platinized electrode.
The working principle of the embodiment is as follows:
firstly, raw water is introduced into the outer shell 1 through the water inlet 11, an electrolyte solution is introduced into the inner shell through the liquid inlet pipe 21, then the grid cathode 5 and the grid anode 6 electrolyze the raw water, the electrode plate 4 in the inner shell 2 electrolyzes the electrolyte solution to generate gas-liquid mixtures with chlorine as a main component, and the gas-liquid mixtures are sent out through the one-way valve 3 and mixed with the electrolyzed raw water to form a hypochlorous acid aqueous solution.
The grid cathode 5 and the grid anode 6 can also be selectively switched on and off in order to adjust the pH value of the electrolyzed water outlet water within a small range.
In conclusion, the embodiment can not only take away the heat generated in the electrolysis process through the raw water, but also effectively electrolyze the chloride ions in the raw water, thereby increasing the effective chlorine concentration of the electrolyzed water.
