Description

  The present invention relates to a brown gas generator having a forced circulation water cooling system.

Brown's Gas is a gas mixture obtained by electrolysis of water and having an equivalent ratio of hydrogen and oxygen of 2: 1. Usually, if water is electrolyzed, hydrogen is obtained at the cathode and oxygen is obtained at the anode. Brown gas is a gas sample that is not collected separately, but is named after Dr. Yull Brown, a native of Bulgaria.
Companies around the world may use aqua gas, water gas, etc. instead of the name brown gas.

(Embodiment 1)
The brown gas generator having the forced circulation water cooling system according to Embodiment 1 of the present invention includes an electrolytic cell (10) and an electrolyte cooling system.

  With reference to FIG. 1a, FIG. 2, and FIG. 3, the brown gas generator which has the forced circulation type water-cooling cooling system by Embodiment 1 of this invention is demonstrated.

  As shown in FIG. 1a, in the Brown gas generator having the forced circulation water cooling system according to the first embodiment, a plurality of electrolytic cells (10) are arranged. Each electrolytic cell (10) includes an electrode rod (20) for supplying (+) power to the upper end and a cylindrical electrolytic cell container (10a) for supplying (-) power, and a connecting wire (10b). Alternatively, a bus bar (not shown) can supply power to the plurality of electrolytic cells (10).

The electrode rod (20) is an electrode installed on the upper part of the electrolytic cell (10) and supplies electricity.
In the first embodiment, as shown in FIG. 1a, the electrode rod (20) is a (+) power source and the electrolytic cell container (10a) is a (-) power source. 20) may be supplied with (−) power and the electrolytic cell container (10a) with (+) power.

  As shown in FIG. 2, a plurality of cylindrical electrode tubes (30) are formed inside the electrolytic cell (10), and the electrode tubes (30) are fixed to the upper and lower portions of the electrode tube (30). An electrode tube fixing port (40) having a gas generating port for smoothly discharging gas and water can be installed.

In the electrolytic cell (10), brown gas is generated between the electrode tubes (30). In order to collect a large amount of the brown gas generated in each electrolytic cell (10), a collecting tube (160) is installed at the upper end of the electrolytic cell (10), and the collected large amount of gas is transmitted through the pipe line.

In this Embodiment 1, it can design so that an discharge port area may be enlarged by making said electrode tube fixing port (40) into a spider structure.
For example, as shown in FIG. 3, it can be designed to increase the discharge gas outlet area of the brown gas or the electrolytic solution by radially forming a plurality of blades from the center.

  On the other hand, as shown in FIG. 1a, when brown gas is generated in the electrolytic cell (10), water in the electrolytic cell (10) is reduced. At this time, the water level sensor (120) in the electrolytic cell (10) is reduced. By sensing the water level and transmitting a signal from the water level sensor (120) to a controller (not shown), the water supply pump (60) is operated, and the water tank (200) (see FIG. 1b). The cooling water supplied from is supplied into the electrolytic cell (10). The supplied water is first supplied to the upper transfer pipe (70) connected to each of the electrolytic cells (10), and is supplied to each of the electrolytic cells (10) evenly through the upper transfer pipe (70). .

  At this time, by adopting a thermistor whose resistance changes depending on the temperature or a water level sensor (120) using a water level ball that moves up and down due to buoyancy, when the water level rises or falls, thermistor reduces the resistance that changes depending on the surrounding temperature. If the water level ball is detected, the water level of the electrolytic cell (10) can be determined stably and continuously by detecting the position corresponding to the water level.

  Further, when Brown gas is generated in the electrolytic cell (10), the temperature in the electrolytic cell (10) rises. At this time, the temperature sensor (130) senses the water level in the electrolytic cell (10) to control the controller.

In order to remove foreign substances and foreign substances present in the water, an electrolyte solution filter (110) can be provided.

For example, in order to remove foreign substances generated in the electrolytic cell (10), filtering is performed by the controller after passive operation by the driver or after a certain period of operation.
At this time, SV1 is turned off (closed) in the solenoid valve for electrolytic solution filter (170), SV2 and SV3 are turned on (opened) to bypass the pipeline, and the electrolytic solution (50) becomes the electrolytic solution filter (110). ) Through the heat exchanger (100). In this way, the pressure on the pipeline is minimized while properly switching between the electrolyte circulation operation and the filtering operation, thereby reducing the load on the pump and extending the life of the filter, thereby achieving stable and sustainable operation. Can be maintained.

  Further, in the case of an operation place where brown gas is used for continuous operation for 24 hours, a stable supply of cooling water is a very important factor. Accordingly, the cooling water cooled in the cooling tower (150) (see FIG. 1b) can be supplied with continuous cooling water by applying a bypass structure pump by a plurality of cooling water circulation pumps (180). Since the cooling water circulation pump (180) is composed of a plurality of pumps, the amount of fluid (cooling water) delivered by the operation of the pump does not change greatly, so that the cooling water flows stably. Can operate continuously
