The following detailed description of the invention refers to the accompanying drawings, which illustrate, by way of illustration, specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It should be understood that the various embodiments of the present invention are different, but need not be mutually exclusive. For example, certain features, structures, and characteristics described herein may be implemented in other embodiments without departing from the spirit and scope of the invention in connection with an embodiment. It is also to be understood that the position or arrangement of the individual components within each disclosed embodiment may be varied without departing from the spirit and scope of the invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is to be limited only by the appended claims, along with the full scope of equivalents to which such claims are entitled, if properly explained. In the drawings, like reference numerals refer to the same or similar functions throughout the several views.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

Hereinafter, the VOCs adsorbing apparatus according to the embodiment of the present invention can adsorb VOCs generated in the engine room in the ship, which can be used for a long time by using a roll-type ACF (activated carbon fiber) .

In addition, the VOCs adsorbing apparatus according to the embodiment of the present invention can be designed so that a roll type ACF filter that can be used for a long time can be replaced to recover VOCs generated in the engine room. Based on the internal fan control, adsorption procedures can be performed on VOCs flowing at a constant flow rate.

Further, the VOCs adsorption apparatus according to the embodiment of the present invention is mounted inside the engine room of the ship. Therefore, unlike existing air purifiers, the influence of noise may hardly be reflected in the design. Therefore, the capacity of the intake fan for intake of VOCs can be estimated according to the required performance. Hereinafter, a VOCs adsorption apparatus according to an embodiment of the present invention may be implemented in an engine of a device other than a ship, and VOCs may be adsorbed, and such embodiments may also be included in the scope of the present invention.

1 is a conceptual view showing a VOCs adsorption apparatus according to an embodiment of the present invention.

Fig. 1 shows a configuration for a VOC adsorption procedure of a VOCs adsorption apparatus.

Referring to FIG. 1, the VOCs adsorption apparatus may include a housing 100, a blower fan 120, and a filter unit 140.

The housing 100 may have an external shape of a VOCs adsorption apparatus for attaching to an engine and a blowing fan 120 and a filter unit 140 may be implemented inside the housing 100. In the housing 100, a coupling unit that can be mounted on a portion of the ship adjacent to the engine can be implemented, and a suction process for VOCs generated by being connected to the engine unit of the ship based on the coupling unit can be performed.

The blowing fan 120 may be configured to introduce the VOCs generated in the engine of the ship into the housing 100 and to filter the filtered VOCs through the filter unit 140. Based on the internal fan control, the blowing amount of the blowing fan 120 can be controlled and the inflow amount of the VOCs can be controlled. An internal flow path may be formed between the blowing fan 120 and the filter unit 140 and the VOCs flowing through the internal flow path may be filtered through the filter unit 140 based on the operation of the blowing fan 120 .

The filter unit 140 may be implemented to filter the VOCs flowing through the blowing fan 120. The roll-type ACF (activated carbon fiber) filter included in the filter unit 140 may be implemented in a replaceable structure. VOCs introduced by the blowing fan 120 can be adsorbed on the basis of the ACF filter. A separate discharge passage for discharging the filtered VOCs to the outside can be implemented in the VOCs adsorption apparatus. The filtered VOCs may be discharged to the outside through the discharge passage.

For example, the discharge passage may be formed in a direction opposite to the direction in which the VOCs flow through the blowing fan 120, and the filtered VOCs may be exhausted to the rear of the blowing fan 120.

ACF is an activated carbon fiber (Activated Carbon Fiber) which is a high performance, high performance adsorbent developed from fiber as raw material. ACF has high adsorption rate and large adsorption capacity, so it can exhibit high performance even with miniaturized ACF.

The housing 100, the blowing fan 120, and the filter unit 140 of the VOCs adsorption apparatus may be implemented with different sizes depending on the size of the installed engine.

2 is a flowchart showing the operation of a VOCs adsorption apparatus according to an embodiment of the present invention.

In FIG. 2, a method for determining the presence or absence of VOCs by the VOCs adsorbing apparatus and performing an operation, and controlling the inflow rate / exhaust rate of VOCs according to the concentration of VOCs is disclosed.

Referring to FIG. 2, the VOCs adsorbing apparatus detects whether VOCs are generated (step S200).

A sensor for determining whether or not VOCs have occurred due to the operation of the engine may be implemented in the VOCs adsorption apparatus. The sensor may be a motion detection sensor that senses whether the engine is operating or an atmospheric detection sensor that senses the presence of VOCs in the atmosphere.

The VOCs adsorber determines the concentration of VOCs when the occurrence of VOCs is detected (step S210).

The VOCs adsorber can adjust the speed of the blower fan adaptively according to the concentration of the incoming VOCs. For example, the speed of the blowing fan can be adjusted in three steps according to the concentration of VOCs. When the concentration of VOCs is below the first threshold concentration, the velocity of the blowing fan can be set to one stage. When the concentration of VOCs is above the first critical concentration and below the second critical concentration, the velocity of the ventilation fan may be set to two stages. If the concentration of VOCs is above the second critical concentration, the velocity of the blowing fan may be set to three stages. This setting is an example and it can be set so that the velocity of the blowing fan relatively increases as the concentration of VOCs relatively increases according to a previously stored formula.

Measurements of the concentration of the incoming VOCs can be performed by the VOCs incoming concentration measurement unit. The measurement of the concentration of these incoming VOCs and the adjustment of the speed of the blower fan according to the concentration of the measured VOCs can be performed periodically. That is, the speed of the blower fan may be periodically changed according to the change of the concentration of the VOCs.

Based on the determined concentration of VOCs, the blowing fan is operated to move the VOCs to the filter unit (step S220).

When the blowing fan is operated, the VOCs can be moved to the filter portion through the internal flow path.

The filter unit performs filtering on the inflowed VOCs, and discharges the filtered VOCs to the outside through the discharge passage (step S230).

The VOCs introduced by the blower fan can be adsorbed on the basis of the ACF filter. A separate vent line for delivering the filtered VOCs may be implemented in the VOCs adsorber. The filtered VOCs may be discharged to the outside through the discharge passage.

3 is a conceptual diagram illustrating an operation of a VOCs adsorption apparatus according to an embodiment of the present invention.

In FIG. 3, the VOCs adsorber measures the concentration of filtered VOCs, and an additional VOCs adsorption procedure is initiated when the filtered VOCs concentration is not below a threshold.

Referring to FIG. 3, a filtered VOCs concentration measuring unit 300 for measuring the concentration of VOCs discharged after filtering may be implemented in the discharge passage. According to the embodiment of the present invention, when the concentration of the filtered VOCs measured by the filtered VOCs concentration measuring unit 300 is equal to or greater than the threshold value, VOCs may be introduced back into the filter section.

According to an embodiment of the present invention, the discharge passage 320 and the re-adsorption procedure flow passage 340 can be realized for the movement of the filtered VOCs discharged from the filter portion. The discharge channel 320 is a channel for discharging the filtered VOCs discharged from the filter unit to the outside and the re-suction channel 340 may be a channel for re-introducing the filtered VOCs discharged from the filter unit back to the filter unit .

The filtered VOCs concentration measuring unit 300 may open only one of the re-adsorption flow path and the discharge flow path depending on the concentration measurement result. When the concentration of the filtered VOCs measured by the filtered VOCs concentration measuring unit 300 is equal to or higher than the threshold value, the re-adsorption flow path 340 is opened and the discharge flow path 320 can be closed. When the concentration of the filtered VOCs measured by the filtered VOCs concentration measuring section 300 is less than the threshold value, the discharge flow passage 320 is opened and the re-absorption flow passage 340 can be closed.

FIG. 4 is a conceptual diagram illustrating a method for determining a replacement time of a filter of a filter unit according to an embodiment of the present invention.

FIG. 4 illustrates a method for determining whether or not to replace a roll-type ACF filter implemented in a filter unit.

Referring to Fig. 4, the filtering performance of a roll-type ACF filter can be reduced due to continuous filtering. The VOCs adsorber makes a judgment as to when to replace the roll-type ACF filter, and when a replacement of the ACF filter is required, a signal indicating the necessity of replacement of the filter can be sent to the user.

For example, the VOCs adsorber may be configured to determine the performance of the ACF filter based on the concentration (400) of the input VOCs measured by the VOCs influent concentration measurement unit and the concentration (420) of the filtered VOCs measured by the filtered VOCs concentration measurement unit It is possible to judge the degree of deterioration of the semiconductor device.

The amount of adsorbed VOCs 440 can be determined based on the concentration 400 of the incoming VOCs and the concentration 420 of the filtered VOCs. If the amount of adsorbed VOCs 440 is measured below a critical amount, the VOCs adsorber may determine that the ACF filter needs to be replaced and deliver a filter replacement request signal to the user.

The VOCs adsorbing device may further improve the accuracy of the filter replacement request signal by transmitting a filter replacement request signal to the user only when the amount of the adsorbed VOCs 440 is less than the threshold value or more than the threshold value.

The user can receive the filter replacement request signal and replace the ACF filter of the VOCs adsorber.

5 is a conceptual view illustrating a filter unit of a VOCs adsorption apparatus according to an embodiment of the present invention.

5, a method of rotating a roll-type ACF filter included in the filter unit is disclosed.

Referring to FIG. 5, the ACF filter implemented in the filter unit of the VOCs adsorption apparatus may be implemented to be rotated based on the roll shape.

The aging of the inside of the roll-type ACF filter may be changed depending on the position of the inflow passage, the discharge passage and / or the inflow direction of the VOCs flowing into the filter portion from the blowing fan. For example, the degree of deterioration of the portion of the ACF filter that first filters VOCs introduced by the blowing fan (inflow channel) may be greater than the degree of deterioration of the other portion of the ACF filter. That is, in a roll-type ACF filter, the filtering performance of a specific portion can be deteriorated faster than the filtering performance of other portions.

Therefore, according to the embodiment of the present invention, the ACF filter can be rotated to improve the utilization of the ACF filter.

For example, the amount 540 of VOCs adsorbed by the ACF filter may be determined based on the concentration 500 of the incoming VOCs and the concentration 520 of the filtered VOCs, as described above. When the amount of adsorbed VOCs 540 is measured below a critical amount, the VOCs adsorber may determine that rotation of the ACF filter is necessary and may rotate the ACF filter by a predetermined angle (e.g., 90 degrees).

For example, when the ACF filter is rotated at one rotation angle of 90 degrees, the VOCs adsorption device can deliver a filter replacement request signal to the user after four rotations of 90 degrees have been completed. The rotation angle may be set by the user, and the number of rotations for transmitting the filter replacement request signal may vary depending on the rotation angle. For example, when the rotation angle is 45 degrees, when the rotation is completed eight times, the VOCs adsorption device can deliver the filter replacement request signal to the user.

6 is a conceptual diagram illustrating a filtering method of a VOCs adsorption apparatus according to characteristics of VOCs according to an embodiment of the present invention.

In FIG. 6, the amount of VOCs adsorbed can vary depending on the time of staying in the ACF filter of the filter portion of the VOCs. For example, the larger the molecular weight of VOCs, the longer the VOCs stay in the ACF filter and the greater the adsorption of VOCs. On the contrary, as the molecular weight of VOCs is relatively small, the time for VOCs to remain in the ACF filter is relatively shortened and the adsorption amount of VOCs can be reduced.

Also, as the temperature of the filter portion and / or the temperature of the VOCs are relatively higher, the diffusion of the VOCs occurs relatively quickly, the time for the VOCs to stay in the ACF filter is relatively shortened, and the adsorption amount of the VOCs can be reduced. On the contrary, the lower the temperature of the filter portion, the slower the diffusion of VOCs occurs, the longer the VOCs stay in the ACF filter becomes, and the adsorption amount of VOCs can be increased.

Referring to FIG. 6, the VOCs adsorption apparatus can adjust the pressure 640 of air flowing into the filter unit in consideration of the type of VOCs 600 and the internal temperature (or VOCs temperature) 620 of the VOCs adsorption apparatus.

For example, the VOCs adsorber determines whether any incoming VOCs are VOCs and, if the molecular weight of the VOCs is below the threshold value, reduces the pressure of the VOCs entering the ACF filter to increase the adsorption rate of the VOCs, It can be prevented from being dispersed. The VOCs adsorption apparatus may be implemented with a VOCs determination unit and a VOCs inflow pressure adjustment unit, and the VOCs inflow pressure adjustment unit may adjust the inflow pressure of the VOCs considering the molecular weight of the VOCs determined by the VOCs determination unit.

In addition, the VOCs adsorption apparatus can lower the temperature inside the VOCs adsorption apparatus when the temperature rises above a certain threshold temperature based on the built-in temperature detection sensor. As described above, when the temperature of the VOCs is too high, the diffusion rate of the VOCs is increased, and the increase of the diffusion rate of the VOCs can reduce the adsorption rate of the VOCs. Accordingly, when the temperature sensed by the temperature detection sensor is increased to a predetermined temperature or more, the temperature inside the VOCs adsorption apparatus can be reduced through the cooling unit implemented in the VOCs adsorption apparatus, thereby increasing the adsorption amount of the VOCs.

The critical temperature value may vary depending on the molecular weight of the incoming VOCs. If the molecular weight is relatively large, the time to stay in the ACF filter may be relatively long, so that the critical temperature value can be set to a relatively higher value. When the molecular weight is relatively small, the time to stay in the ACF filter may be relatively small, so that the critical temperature value can be set to a relatively smaller value.
