Description

Adsorption apparatus, adsorption system, and adsorption method using activated carbon fiber {Absorption apparatus using Active carbon fiber}

The present invention relates to an adsorption device and adsorption method using activated carbon fibers, and more particularly, to adsorption of harmful gases using active carbon fibers and adsorption by cooling means provided on the outer surface of the housing in adsorption mode. Regarding the adsorption device and adsorption method using activated carbon fibers that can improve efficiency and regenerate by quickly heating ACF without a large heating means such as separate steam input through energization by a voltage application unit in the regeneration mode. will be.

The prior art involves adsorbing contaminants contained in gases on activated carbon for a long time and regenerating this activated carbon for a new adsorption process. The activated carbon used for this purpose is mainly activated carbon fibers in the form of granular fillers in fixed beds, or in the form of nonwoven fibers, woven fibers, or knitted fibers.

DE 100 32 385 A1 describes a method for regenerating electrically conductive adsorbents containing organic substances, which are heated by conducting an electric current. The flush gas is not conducted through the adsorbent by conduction of current, and then the current is turned off so that the flush gas is conducted through the adsorbent, and the adsorbent is alternately heated continuously in time, in this way, the adsorbed organic material is It is extracted and the adsorbent is cooled simultaneously.

The prior art also describes a method for adsorption and regeneration using an adsorption unit comprising at least one activated carbon fiber and wherein the activated carbon fiber is heated by an electric current (EP 1 284 805 B1). Activated carbon fibers are designed in such a way that the activated carbon fibers create sufficient electrical resistance for heating. The gas flow is conducted into the heated activated carbon fiber to selectively adsorb at least one component of the gas flow. The adsorbed component is desorbed in the presence of an inert gas flow by means of controlling or regulating the temperature of the activated carbon fiber to the temperature for desorption using a current flow.

In addition, EP 0 532 814 B1 describes a device for treating fluids containing at least one constituent. Such known devices have a structure made of an adsorbent material that is traversed by a flow of fluid to adsorb the adsorbable constituents by the adsorbent, the structure being placed in a processing vessel. The device comprises means for periodically regenerating the adsorbent material by means of a Joule-Thomson effect, the means cooperating with the structure during a desorption phase consisting of conducting an electric current through at least one of the layers of the structure. It is used to The structure includes layers of electrically conductive activated carbon that are overlapped and connected in a zigzag shape obtained by weaving an electrically conductive fiber. The layers are spaced apart from each other, so turbulence is generated as the fluid to be treated flows through the layers. Current flows through the fibers in the fiber direction (in the longitudinal direction) through a potential difference applied to the ends of the layers made of activated carbon or the ends of each layer. The gas to be treated is supplied through a perforated pipe into the layers wound around the pipe.

[0007] In addition, DE 41 04 513 C2 describes an adsorber made of an adsorbent material that is electrically conductive and can be heated by means of an electric current to a temperature at which the adsorbent material is desorbed. Pressurized or fibrous activated carbon present in the form of a tube, hollow fiber, or mat through which the contaminant-containing fluid can flow is used as an adsorbent, electrically conductive material. The tubes, hollow fibers, or mats are clamped at their end faces between the two electrodes, and current flows through the tube, hollow fibers, or mat in its longitudinal direction.

US 4 737 164 A discloses a method for recovering volatile impurities from a gas, wherein the gas is rolled up and heated by means of DC current for desorption and increasing its adsorption capacity. Flow through The rolled up activated carbon fiber fabric is, at its end face, connected to an electrode connected to a DC voltage source.

In addition, DE 698 27 676 T2 discloses an electrically renewable air filter media, the filter media including:

(A) Electricity that includes a carbon fiber composite molecular sieve for adsorption of impurities from a non-acceptable, inflowing air flow, and allows the outflow of an acceptable air flow. As a conductive filter medium, the carbon medium made of a carbon fiber composite molecular sieve is activated carbon additionally containing multiple porous carbon fibers bonded to an open permeable structure by means of a carbonizable organic binder. A fiber composite material, the composite material having a porosity in the range of approximately 82-86% and a surface area greater than 1000 m 2 /g prior to activation;

(B) regeneration means including a generator for electric current, which causes electric current to pass through the filter medium to desorb adsorbed impurities from the filter medium; And

(C) encapsulation means for conducting desorbed impurities away from acceptable air.

In all these known solutions, an electric current is applied to the activated carbon fibers along their longitudinal extension (fiber axes), thereby leading to non-uniform heating of the activated carbon fibers along the axial length of the activated carbon fibers in the adsorber module. And, therefore, the desorption of contaminants from activated carbon fibers has the drawback that it adversely affects, and may even remain incomplete. Therefore, adsorber modules with mats of activated carbon fibers, hollow fibers, or tubes using electric regeneration have not been successful so far.

In addition, these adsorber modules with hollow fibers, tubes or wrapped-around mats made of activated carbon fibers induce a different pressure distribution of the gas along its axial length, which leads to local saturation. Resulting in a non-uniform flow profile and non-uniform filling having regions of the flow, thereby leading to a poor ratio of the adsorber surface available to be traversed by the flow and the adsorber surface area substantially traversed by the flow.

In addition, electrostatic discharge occurs while the pollutant-containing gas flows through mats, hollow fibers, or tubes made of activated carbon fibers, which causes uncontrolled electric shock and discharge to cause fire and reduce the safety of the adsorption system. It creates a risk of endangering.

Further, hollow fibers, tubes, and wrap-around mats made of activated carbon fibers do not have sufficient mechanical safety and are not easy to handle for maintenance and replacement purposes. Therefore, known adsorber modules are susceptible to interference, have unsatisfactory efficiencies, and are therefore ultimately not cost effective.

A sixth step in which the activated carbon fiber of the ACF module is heated and the adsorbed harmful gas is desorbed and discharged to the spaced space; And
A seventh step in which the harmful gas is discharged through a connection pipe and a confluence pipe by a vacuum pump.
◈ Claim 17 was abandoned upon payment of the set registration fee. The method of claim 16,
When regeneration is complete and re-switching to adsorption mode,
An adsorption method using activated carbon fibers, characterized in that the voltage application unit and the vacuum pump are stopped, the valve is opened, the cooling means is operated, and the first to third steps are performed.
In the adsorption system,
A plurality of adsorption devices according to any one of claims 1, 7, 9, 10, 12 and 13 each independently connected in parallel;
A valve provided at an inlet end of each of the adsorption devices; And
An adsorption system using activated carbon fibers comprising: a control unit for controlling to open a valve of the adsorption device to be operated in the adsorption mode and close the valve of the adsorption device to be operated in the regeneration mode.
