Description

Brown gas automatic feeding device using air-cooled electrolytic cell {BROWN GAS AUTO SUPPLY APPARATUS USING AN AIR COOLING ELECTROLYZER}

The present invention relates to an automatic brown gas supply device using an air-cooled electrolytic cell, in order to greatly enhance the cooling effect that is easily lacked because it is air-cooled while taking advantage of the air-cooled electrolytic cell by the natural circulation method of the electrolyte in configuring the brown gas automatic supply device. will be.

An electrolytic solution cooling device is Patent No. 10-0630803, "Electrolyte Automatic Temperature Controller," which is filed and filed by the present applicant. The electrolytic solution thermostat is practically used as a component of Patent No. 10-0497873 "Brown Gas Automatic Supply System (aka Brown Gas Plant)" registered and filed by the present applicant.

The automatic temperature control device of the electrolyte is a cooling device adopting a forced cooling method by a refrigeration cycle by forced circulation of the electrolyte by the electrolyte circulation pump, so that the temperature of the electrolyte is kept constant no matter how long the electrolysis apparatus is operated, so that the brown gas is stable. It is configured to be supplied with.

Therefore, since the electrolyte thermostat is the most efficient cooling method by the refrigeration method, it is already practically used in the brown gas automatic supply device of the large model, and is especially used for the brown gas plant exceeding 20,000 l / h class. However, it is a problem that consumers who need medium to large models of 6,000 to 8,000 l / h cannot use the large-size refrigeration model due to the size and cost of the product.

In other words, it is necessary to consider that Brown gas generators have different sizes according to their needs because consumers vary from application to application. The following table shows the application-specific models of gas generators currently on the market.

As shown in Table 1, the gas generator requires a product having a different gas production amount according to the use, so a small, medium, medium and large model must be made and the gas plant must be engineered.

Therefore, the applicant had no choice but to develop all of the models. What was learned in the process of developing models for each capacity and developing each model according to the gas production amount was found that the different models affect the gas production and the cooling method should be different each time.

In other words, even if the capacity of the same type of electrolysis device is increased, the capacity of the electrolysis device does not increase in proportion to the amount of electricity input by Faraday's law. The problem is that product development is not easy.

Therefore, every time a new model is developed, performance is not known unless it is tested at the actual size in the field, and a new technology must be created each time. This difficulty of electrolysis can be seen by the fact that no technological progress has been made in the last 50 to 60 years, and that no one has thought of using water as a fuel.

The present invention is to solve this problem is to install the cooling tank attached to the upper electrolyte tank and the aluminum heat sink in the upper part of the air-cooled electrolytic cell, and to install the lower electrolyte tank in the lower part of the electrolytic cell, and the gas exhaust nibble formed on both sides of the air-cooled electrolytic cell Connect the gas inlet nibble of the upper electrolyte tank with a gas riser, and connect the electrolyte down pipe between the cooling tank and the lower electrolyte tank, and the electrolytes formed on both sides of the nitrogen and air-cooled electrolytic tanks formed on the lower electrolyte tank. It is configured to connect with the inlet nibble through the electrolyte riser tube and rise with Brown gas generated from the air-cooled electrolyzer, so that the electrolyte collected in the upper electrolyte tank is naturally circulated and refilled into the air-cooled electrolyzer.

The present invention relates to a brown gas automatic supply apparatus using an air-cooled electrolytic cell, and an object of the present invention is to create a method for greatly increasing the cooling effect while the electrolyte cooling method is not a refrigeration method but an air cooling system. To provide.

In general, when the capacity of the electrolyzer is increased, heat is generated so much that there is no limit to air cooling, but if air cooling is adopted, the product is compact, occupies a small place of installation, and the price of the product is low, so it is necessary to adopt air cooling as much as possible.

The model adopting such an air-cooled type is Patent No. 10-0780515, entitled "Brown Gas Automatic Feeding Device Using an Air-Cooled Electrolyzer" (hereinafter, referred to as a prior patent), filed and filed by the present applicant.

This prior patent corresponds to the medium model of Table 1 in the gas production amount of 3,000ℓ / h ~ 4,000ℓ / h described in the detailed description of the invention

`` In addition, the cited patent 2 is suitable for small and medium-sized brown gas generators of 300 l / h to 2000 l / h gas production rate, and it can be seen that the cloth flow fan is installed on the upper surface of the electrolytic cell to increase the cooling effect. It is widely used in jewelry processing, glass processing, brazing, gas welding, etc., and it does not consume much water, so it does not need automatic supply of supplemental water.

However, the present invention relates to a medium-to-large brown gas generator of 3000 l / h ~ 4000 l / h class gas production is increasing rapidly these days to propose an automatic brown gas automatic feeder interlocked with an automatic water supply device for continuous operation.

In the case of such a medium-large brown gas generator, unlike the cited patent 2, a large number of electrolyzers must be configured to increase the capacity, so the flow volume of the cloth flow fan has a limited electrolyzer size, which makes it difficult to increase the capacity, and the overall structure becomes complicated. Sufficient cooling effect can not be expected.

The present invention is to put the Brown gas automatic feeding device of the medium and large model into a high-tech process automated in a continuous process. For example, it aims to provide fuel supply for vacuum glass tube automatic cutting device using brown gas, which is used for cutting vacuum glass tube, which is essential for PDP / LCD panel line process such as Samsung / LG Electronics.

Another example is to use a brown barbecue fuel supply device using a brown gas heating device that automatically produces 300 delicious barbecues a day without any seasoning using brown gas.

The present invention in consideration of the various circumstances as described above is composed of an electrolysis chamber incorporating a large-capacity blower and a protruding electrolytic cell, and a water supply unit chamber incorporating a supplemental water supply device, in an air-cooled method rather than refrigeration. It is an object of the present invention to provide an automatic brown gas supply device capable of sufficiently cooling the electrolyte solution.

The overall configuration of the present invention is a predetermined number formed on the lower surface of the electrolysis chamber A of the main body 110 in which the electrolysis chamber A and the water supply device chamber B are formed as shown in FIGS. The electrolyte inlet 112, the air-cooled electrolytic cell 120 installed on each air inlet 112, the electrolyte inlet 123 and the gas discharge hose 124 connected to the electrolytic solution installed on the electrolytic cell 120 The tank 130, the power supply device 140 for supplying the (+) (-) DC power supply, and the air blower 150 is installed on the upper surface of the electrolysis chamber A, so that the outside flows from the air inlet 112. An electrolysis device (101) configured to efficiently cool air while passing between the protruding electrode plates (121) of the air-cooled electrolytic cell (120) at a high speed; Pressurized water purifier 160 connected to the water pipe, a water tank 170 for storing purified water, and pressurized water to supply replenishment water by the instruction of the water level sensor 131 in the electrolyte tank 130. The supplementary water automatic water supply device 102 including the pressure pump 181 and the pressure tank 182 assembled to the angle sheet 183 is installed in the water supply device room B, and the electrolysis chamber A and It is configured to be integral.

As shown in FIG. 7, the electrode plate 121 of the air-cooled electrolytic cell 120 of the present invention has a portion protruding out of the spacer 122 when the spacer 122 is assembled with the stay ring together with the O-ring 122a. The upper part is protruded very little, the lower part slightly protrudes, and the left and right sides are formed in the longitudinal direction so as to increase the cooling efficiency.

The electrolytic cell 120 is installed at a predetermined height on the air inlet 112 formed on the lower surface of the electrolysis chamber (A) to assemble the insulating bracket 114 in each electrolytic cell 120 to the angle sheet 113 Install and install the electrolyte tank 130 on the upper part of the electrolytic cell 120, but install the (+) and (-) pole separately formed on either side of the electrolytic cell 120, the electrolyte tank 130 also After the installation is divided into (+) pole tank and (-) pole tank and connected between the electrolytic bath 120 and the electrolyte tank 130 of the same pole with the electrolyte inlet hose 123 and the gas discharge hose 124, respectively The electrolyte is to circulate naturally inside the electrolytic cell 120. At this time, the electrolyte is filled inside through the electrolyte flow hole 121b formed in the electrode plate 121 of the electrolytic cell 120, and when power is applied from the power supply device 140, the positive and negative poles Electrolysis of water occurs between the electrode plate 121 and the brown gas generated at this time passes through the gas discharge hose 124 through the gas distribution hole 121c formed in the upper portion of the electrode plate 121 together with some electrolyte solution and then the electrolytic cell tank Collected at the top of 130.

Brown gas generated in the electrolyzer 120 continues to be discharged to the electrolyte tank 130 through the gas discharge hose 124 together with some electrolyte, so that the electrolyte continues into the electrolyzer 120 through the electrolyte inlet hose 123. It is filled. ”

As can be seen from the above patents, the cooling methods are different for each model, the small and medium-sized models with gas production capacity of 300 to 2,000 l / h use a crossflow fan, and the refrigeration method is adopted for the large model and the plant by the column type electrolyzer. It can be seen that.

In the preceding patent, the 3,000 to 4,000 L / h class is referred to as a medium-large model, but the new model of the present invention is referred to as a mid-size as shown in Table 1.

Medium to large models of the 6,000 ~ 8,000ℓ / h class of the present invention is to meet the needs of large factories such as heavy industry sites and POSCO, 3,000 ~ 4,000 l / h medium models are small, the gas production is not suitable for use, and the freezing method is Bulk is pointed out as a problem.

Because factories such as heavy industry sites and POSCO are already laid out with existing facilities, there is no place to install new facilities, so the smallest possible size is required.

In order to develop a medium-to-large model according to this need, the prototype was first experimented with a large electrolytic cell capacity of 6,000ℓ / h in the prior patent method. As a result of the test, the problem that appeared when the capacity was increased by the prior patent method was that the electrolyte flowed poorly and the temperature of the electrolyte continued to rise beyond 80 ° C due to overheating of the electrolyte.

In this case, if the electrolyte flow is not good, the electrolyte precipitate tends to precipitate between the electrode plates of the electrolytic cell after prolonged use.

As such, it was concluded that the medium-to-large model could not be developed by the prior patent method. Therefore, the automatic supply device based on the new configuration had to be created.

Therefore, the present invention solves the problems caused by the air-cooling method while using the advantages of the prior patent as it is to provide a medium-large Brown gas automatic supply device.

As shown in FIG. 1, when the overall configuration of the electrolytic chamber A of the prior patent is viewed, an air inlet 112 is formed at a lower end of the main body 110 of a sealed structure, and an air-cooled electrolyzer immediately above the air inlet 112 ( Install a predetermined number of 120 and installed two electrolytic solution tank 130 on the (+) pole and (-) pole on the upper side of the electrolytic cell 120, respectively, and a large blower 150 on the upper surface of the main body 110 The external air flowing from the air inlet 112 according to the operation of the blower 150 is configured to cool the electrolyte while passing between the electrode plates of the air-cooled electrolytic cell 120.

Thus, the prior patent pointed out the problem that the electrolyte flow is not good by installing the electrolyte tank only in the upper part of the electrolyzer, and when the gas generator is used for a long time, foreign matters are precipitated between the inner plates of the electrolyzer, resulting in overheating of the electrolyzer. This occurred.

Therefore, if the capacity is increased to a medium-large model of 6,000 l / h or more gas production in such a configuration it is impossible to achieve the object of the present invention for developing a medium-large model because the continuous operation is not possible due to the rise in electrolyte temperature. As a result, it is desirable to newly configure the precipitation tank so as to improve the flow of the electrolyte and prevent the deposits from accumulating inside the electrolyzer.

The purpose of the present invention is to develop a medium-large model of 6,000 l / h or more by the automatic circulation of the electrolyte solution by air-cooling, and above all, configure the shape and arrangement of the electrolyte tank so that the electrolyte is well circulated and the deposits do not accumulate inside the electrolytic cell. Configuring has emerged as a challenge to be solved.

The present invention is configured to horizontally configure the upper electrolyte tank and the lower electrolyte tank, respectively, in the upper and lower portions of the electrolytic cell as a means for solving the above problems, and connected to the cooling tank of the rectangular parallelepiped to the lower end of the upper electrolyte tank cooling It is configured to increase cooling effect by air cooling by aluminum heat sink attached to front and back of tank. Therefore, the warmed electrolyte during the production of brown gas inside the electrolyzer rises through the connection pipe connected with the upper tank to the upper tank and falls on the surface of the upper tank, and the electrolyte collected in the upper tank cools down through the cooling tank. The electrolyte is moved to the lower electrolyte tank and the electrolyte collected in the lower electrolyte tank is configured to be continuously filled into the air-cooled electrolytic cell that generates Brown gas.

In this configuration, brown gas generated in the electrolytic cell is easily discharged along with the electrolyte into the space above the surface of the upper electrolyte tank, so that the electrolyte circulates to the upper tank and the lower tank at a very high speed as if it were acting as a pump.

In particular, the heat sink of the cooling tank is not manufactured directly, but the aluminum heat sink, which is a commercially available product, can be purchased and attached to the front and rear surfaces of the cooling tank. It is configured to cool sufficiently.

In addition, the electrolyte cooling tank and the lower electrolyte tank are installed horizontally so that the electrolyte flows slowly in a wide space horizontally so that deposits in the electrolyte naturally accumulate on the lower surface of the cooling tank and the lower electrolyte tank, and the accumulated deposits are opened when the drain valve is opened and cleaned. Configure to remove.

As a result, the present invention divides the electrolyte tank into upper and lower parts and installs a cooling tank by an aluminum heat sink to quickly circulate the electrolyte flow as if it is circulated by a circulation pump, thereby completely solving the problem of cooling by air cooling.

Therefore, the present invention is to protrude the electrode plate, which is a feature of the air-cooled electrolytic cell to the outside to allow the air to pass between the electrode plate while taking advantage of the good heat-dissipating effect of the high efficiency air-cooled electrolytic cell while maintaining the advantages of the above-mentioned various problems that are not enough to be insufficient only in the electrolytic cell It is possible to provide 6,000ℓ / h Brown gas automatic feeding device of medium and large model.

In order to confirm the effect of the present invention, a prototype of 6,000 L / h BN-6000 model was made and checked as follows.

Install the bulkhead in the middle of the upper and lower part of Brown gas automatic feeding device's inner space so that the upper and lower spaces are formed in the upper and lower parts, and the upper air inlet is formed in the lower part of the upper space. Large ventilators were installed to allow air to pass through the cell in large quantities.

The electrolyzer used the electrolyzer used in the 3,000 L / h model BB-3000 as it is, but because the quantity is required twice, all eight tanks were installed in a row.

The electrolyte tank of the present invention is formed in a cylindrical shape but is installed horizontally without standing vertically. Therefore, the upper electrolyte tank was installed left and right in the upper space of the main body, and a cooling tank formed of a rectangular parallelepiped under the upper electrolyte tank was formed to attach an aluminum heat sink to the outer wall of the cooling tank.

In addition, after installing the lower electrolyte tank left and right in the lower space, the electrolytic solution circulation system was prepared by separating the (+) and (-) poles by the electrolytic cell and the connection hose.

One line of the connection hose was to check the flow rate of the electrolyte using a transparent vinyl hose.

As a result of confirming the operation state by observing the transparent vinyl hose after applying the power to the prototype thus constructed, it was confirmed that the electrolyte was discharged from the electrolyzer to the upper electrolyte tank at a very high speed with Brown gas.

After checking the temperature of the electrolyte while continuously operating for 5 hours, the temperature was gradually increased at the first 18 ℃ (current temperature of the laboratory), and after 35 minutes, the temperature was recorded at 52 ℃ and it was confirmed that the temperature was kept no longer rising.

As a result, even in the case of the 6,000 L / h medium-large model, it was confirmed that the present invention can be efficiently cooled by the air-cooled electrolyte natural circulation method, thereby achieving the object of the present invention.

In another aspect, the present invention is characterized by the horizontal configuration of the electrolyte cooling tank and the lower electrolyte tank so that the electrolyte flows slowly through a wide space. This is because the deposits in the electrolyte naturally accumulate in the cooling tank and the lower electrolyte tank, so that the precipitates do not enter the electrolytic cell, thereby resolving the problem of deposits accumulated between the inner plates of the air-cooled electrolytic cell, resulting in poor electrolytic efficiency.

Therefore, the present invention is formed by dividing the main body into the upper space and the lower space, the upper electrolyte tank in the upper space horizontal configuration, the lower electrolyte tank in the lower space horizontal configuration and the cooling tank cooled by the aluminum heat sink under the upper electrolyte tank It is possible to provide an automatic brown gas supply device using an air-cooled electrolytic cell that can naturally circulate the electrolyte smoothly while greatly increasing the cooling effect.
