The present invention, more particularly impurities adsorbed by the activation of active carbon by performing a process for producing hydrogen gas (H ₂ Gas) and play an active carbon in a row to an apparatus for reproducing the activated carbon in a hydrogen production process The present invention relates to an active carbon regeneration apparatus of a hydrogen production process capable of stably producing high purity hydrogen gas by improving capacity and extending the lifetime of activated carbon.

In general, hydrogen production includes electrolysis of water electrolysis, pyrolysis of hydrogen, and separation from water gas or coke oven gas.In the steel industry, coke oven gas (COG; COKE) Separation from OVEN GAS is widely used.

The conventional hydrogen regeneration process for separating hydrogen from such COG and a method of regenerating active carbon performing the same are provided by receiving a raw material COG through the COG supply pipe 300 as shown in FIG. To maximize the kinetic energy between the gas molecules. Then, the compressed heat generated at this time is lowered in a cooler (not shown), and the condensate generated by the temperature change is separated and discharged from the condenser 302, and the pressure-adjusted COG is absorbed (hereinafter, PSA: PRESSURE SWING ADSORBER). And the automatic filter valve 310 to the preliminary filter 303a and the adsorption tower 303b.

Raw material COG introduced into the preliminary filter 303a and the adsorption tower 303b is a capillary phenomenon and van der Waals forces in the pores of an active carbon having a large inner surface area, which is a filler of the preliminary filter 303a. ), A highly volatile fluid (naphthalene, benzene, toluene, xylene) is adsorbed and separated into pores, and the CMS (CARBON MOLECULAR SIEVES), ZMS (ZEOLITE MOLECULAR SIEVES), etc. Gas having a small molecular diameter is adsorbed and separated by an adsorbent of, finally hydrogen gas having the smallest gas molecule diameter and the fastest diffusion rate, and oxygen and nitrogen gas are sequentially discharged through the automatic control valve 312. At the outlet (303b), 99.999% hydrogen purity is obtained.

As described above, the preliminary filter 303a and the impurities adsorbed on the packing material of the adsorption tower 303b become adsorption saturation state as the hydrogen separation time elapses in the PSA 303. Regeneration is performed to discharge the impurities adsorbed in the packing of the adsorption tower (303b), the regeneration process is the automatic supply of the raw material COG to the preliminary filter (303a) and the adsorption tower (303b) of the pair during the adsorption The control valve 310 and the automatic control valve 312 which discharged the produced hydrogen are closed, and at the same time, the automatic control valve 310 which supplies raw material COG to the preliminary filter 303a and the adsorption tower 303b of another tank is manufactured. The automatic control valve 312 for discharging hydrogen is opened to produce hydrogen.                         

Then, the preliminary filter 303a and the adsorption tower 303b of the replaced side are discharged from the pipeline supplied to the oxygen remover 340 after the automatic waste gas discharge automatic control valve 314 is opened to discharge the remaining pressure therein. The regenerative hydrogen supply automatic control valve 315 and the entrance automatic control valve 313 installed in the installed pipe are opened to supply hydrogen produced in the order of the adsorption tower 303b and the preliminary filter 303a to be adsorbed into the active carbon pores. The impurities are desorbed and regenerated, and the waste gas from which the impurities are desorbed is introduced into the gas purification process through the waste gas discharge pipe 345, purified, and recycled.

On the other hand, the hydrogen produced in the PSA (303) is introduced into the oxygen remover 340 to synthesize the oxygen contained in the hydrogen by the catalytic action of the internal filling palladium, and then sent to the dryer (350) dryer ( Drying the water synthesized in 350) is sent to the use place through the hydrogen discharge pipe 355, the adsorption tower 360 on one side of drying the moisture from hydrogen for a predetermined time in the dryer 350 is an automatic control valve 357 After replacing with the preliminary tower (260 ') on the side by the operation of (358) (359), supply the manufactured hydrogen heated in the heater 370 to the dryer 350 of the replaced air adsorption tower 260 to dry The gas is cooled to below normal temperature in the cooler 372 and sent to the preliminary tower 260 'which is being adsorbed again. When the heating and drying is completed, the hydrogen is sent in the reverse order of the heating to cool the tower 260, and then wait for the next process. The above processes are sequentially performed to supply hydrogen to a manufacturing place.

However, in the conventional hydrogen production process as described above, in regenerating the activated carbon filled in the preliminary filter 303a of the PSA 303, the activated carbon is produced by naphthalene, benzene, toluene, by capillary action and van der Waals force. Although volatile fluids such as xylene and water are easily adsorbed, they are viscous, sticky liquids and sublimable materials, and are not easily desorbed from activated carbon, which causes hydrogen quality defects in producing hydrogen, and desorption of the impurities. Impurities accumulate in the active carbon pores and impede activation due to a decrease in performance, thereby shortening the life of the active carbon.

Therefore, the active carbon is regenerated, and an active carbon regeneration process according to the prior art is shown step by step in FIG. The summary is as follows.

First, the COG is compressed in the COG compressor 301, the hydrogen gas is manufactured in the PSA 303, and the oxygen remover 340 removes the oxygen contained in the hydrogen gas. Water vapor generated in the dryer 350 is removed, and in this process, the hydrogen produced from the PSA 303 is returned to the preliminary filter 303a and the adsorption tower 303b of the PSA 303 to activate the inside thereof. It was to recycle carbon.

In addition, if the concentration of benzene is measured on the exit side of the preliminary filter 303a on a regular basis and the concentration is detected above a predetermined value (100 PPM), the preliminary filter 303a to prevent contamination of the fillers in the adsorption tower 303b and to secure hydrogen quality. ) Open the inside to take out the activated carbon and charge new activated carbon.At this time, a large amount of dust is generated, which is harmful to worker's health, and even if it is sufficiently substituted with inert gas, Volatile gases spontaneously ignite, resulting in a fire, and thus all the activated carbon is incinerated, causing manufacturing costs to increase.

In order to solve these problems, active carbon regeneration apparatuses such as Japanese Patent Application Laid-Open No. 2001-8922 (microwave heating method and control device thereof) and Japanese Patent Application Laid-Open No. 2001-146411 (Activated carbon regeneration device) have been proposed. It is not possible to take out the activated carbon used offline and charge the activated carbon into the above-mentioned device and regenerate the activated carbon by microwave and electric heating respectively. Was.

The present invention has been made to solve the above-mentioned conventional problems, the purpose of the active by using the hydrogen gas heated on-line without opening the pre-filter so that impurities are effectively discharged without accumulating inside the active carbon pores It is an object of the present invention to provide an improved activated carbon regeneration apparatus and method for extending the life of carbon and at the same time stably producing high purity hydrogen gas.

Hereinafter, the operation of the present invention with reference to the drawings in detail.

The adsorption tower 303b and the preliminary filter 303a of the PSA 303, which were performing hydrogen production, were replaced with another set of the adsorption tower 303b and the preliminary filter 303a, and then the adsorption tower 303b and the preliminary filter 303a which were used. When regeneration of the activated carbon is carried out, regeneration hydrogen is supplied from the regeneration gas supply pipe 17. The process is as follows.

First, the adsorption tower 360 for drying hydrogen in the dryer 350 is replaced and 120 Nm 3 / hr of renewable hydrogen is supplied to the heater 370 and heated in the heater 370, and then the replaced air adsorption tower 360 ' Part of the regenerated hydrogen heated by the automatic control valve 359 is recovered to the dryer 350 through the cooler 372, and part of the regenerated hydrogen is regenerated by the activated carbon regeneration device 1 according to the present invention. When regenerated hydrogen 50 to 60 Nm3 / hr heated to the gas inlet pipe 32 is introduced, the heated hydrogen gas is heated to the hydrogen gas heated through the nozzle hole 35a processed in the upper portion of the ring pipe 35. Supply to 30a.

In this case, when the driving motor 80 of the driving unit 50 is driven and the driving shaft 65 fixed to the bearing block 67 is rotated by the driving of the driving motor 80, the driven shaft 52 connected by the gear is rotated. As the lower blade 60 and the upper blade 62 rotate as the driven shaft 52 rotates, the ceramic ball 38 filled in the heating part 30a is rotated to be supplied through the ring pipe 35. A portion of the energy of the hydrogen gas heated by contacting the hydrogen gas and the ceramic ball 38 heats the ceramic ball 38 while regenerating gas having a temperature of 100 to 120 ° C. through the upper cloth network 40 to the regeneration gas side pipe 15. To discharge.

By rotating the ceramic ball 38 by rotating the lower blade 60 and the upper blade 62 as described above, the temperature raising time of the ceramic ball 38 is shortened, and the temperature raising efficiency can be increased with less energy. The regeneration process is changed from heating to cooling by changing the regeneration process (heating-> cooling-> atmosphere) of the dryer 350, and the activated carbon regeneration device in the ceramic ball 38 which has been heated even though hydrogen gas at room temperature is introduced. By transferring heat energy into the hydrogen gas introduced into (1), the temperature of the hydrogen gas can be raised to 100 to 120 ° C, and through this, the discharge temperature of the active carbon regeneration device 1 is always kept constant at 100 to 120 ° C. Can be.

On the other hand, the recycled hydrogen discharged at a flow rate of 50 to 60 Nm 3 / hr and a temperature of 100 to 120 ° C. through the regeneration gas discharge pipe 15 of the active carbon regeneration device 1 is automatically configured in the regeneration gas discharge pipe 17. The adsorption tower 303b and the preliminary filter 303a through the automatic control valve 313 of the adsorption tower 303b of the control valve 315 and the PSA 303 flow into the adsorption tower 303b and the preliminary filter 303a to evaporate moisture adsorbed to the pores of the active carbon. Or a drying step of desorbing the low boiling point material, followed by a low temperature pyrolysis step of deboiling the high boiling point material and then desorbing the low boiling point material, and finally performing an activation step of restoring the activated carbon to its original state, 303b) After the lower waste gas discharge automatic control valve 314 is introduced into the cooler 97 installed in the waste gas discharge pipe 345 and the temperature is lowered to room temperature or lower, the waste gas containing impurities separated into active carbon is gas purified. Recovered to an apparatus (not shown) for purification.

If the temperature of the zeshen hydrogen gas flows below 100 ° C. in the regeneration of the activated carbon, moisture, which is one of the main factors for determining the adsorption capacity of the activated carbon, is not removed, thereby increasing the pore volume and thus the life of the active carbon. When this becomes short and the temperature exceeds 120 ° C, the activated carbon deteriorates and ash is generated in the pores, so that the hardness of the activated carbon and the surface area of the pores of the activated carbon are reduced, and the adsorption capacity of the activated carbon is reduced.

If the flow rate is less than 50 Nm3 / hr, the efficiency of the activated carbon is not increased to the required temperature for regenerating the activated carbon during the regeneration process of the activated carbon (drying step-> low temperature pyrolysis step-> activation step). If the life is shortened and the flow rate exceeds 60 Nm3 / hr, the activated carbon regeneration efficiency is improved, but the amount of hydrogen produced in the PSA 303 is increased, and the purity of the hydrogen is lowered, resulting in a decrease in quality. 60 Nm 3 / hr is preferable.

That is, the active carbon regeneration process of the present invention as described above is shown step by step in FIG. The summary is as follows.

First, the COG is compressed in the COG compressor 301, the hydrogen gas is manufactured in the PSA 303, and the oxygen remover 340 removes the oxygen contained in the hydrogen gas. The water vapor generated in the dryer 350 is removed from the dryer 350, and in this process, the regenerated hydrogen drawn from the dryer 350 is heated by the heater 370, and the temperature is raised to a predetermined temperature and the preliminary filter of the PSA 303 is again.
