Description

Corrosion detector for scrubber for marine vessel

The present invention relates to an apparatus for detecting corrosion of a scrubber for a marine vessel, and more particularly, to a corrosion detecting device for a scrubber for a marine vessel for detecting a corrosion state inside a scrubber, which is a desulfurization facility of a marine vessel.

A scrubber is used to treat exhaust gas emitted from a ship's engine or boiler, and is one of the facilities that must be provided for each ship in order to prevent environmental pollution. In particular, as the international regulations on sulfur oxide (SOx) emissions of ships are being strengthened day by day, the desulfurization efficiency of the scrubber needs to be further reinforced in response to this.

In order to increase the desulfurization efficiency of the scrubber, various factors such as the internal structure of the scrubber, selection of a cleaning means, and exhaust gas flow inside the scrubber should be considered.

In addition, since the inner wall of the scrubber is directly exposed to various corrosion-inducing factors contained in exhaust gas, the inside of the scrubber must have strong corrosion resistance. Otherwise, malfunction due to corrosion occurs in various exhaust gas treatment components installed in the scrubber.

As an example of the above-described scrubber, the preceding Republic of Korea Patent Publication No. 10-2019-0000276 discloses a scrubber.

And, as the curtain function is provided, the exhaust gas is minimized to directly contact the inner wall surface of the scrubber, and the effect of reducing the occurrence of corrosion inside the scrubber can be expected.

However, even if the above-described corrosion generation reduction means is provided, since the progress of corrosion inside the scrubber cannot be prevented, various measures such as scrubber drive control and replacement of parts must be performed in response to the progress of corrosion.

However, the prior literature does not disclose any means for detecting the corrosion state inside the scrubber, which causes a problem in that it is difficult to perform maintenance of the scrubber in a timely manner.

Next, FIG. 8 is a configuration diagram showing the monitoring unit shown in FIG. 2 . And, FIG. 9 is a flowchart illustrating an example of driving the monitoring unit shown in FIG. 2 .

Referring further to FIG. 8 , the monitoring unit 400 may include a voltage application unit 410 , a detection unit 420 , and an operation unit 430 . Further, referring further to FIG. 9 , the monitoring unit 400 may perform an initial value setting step S100 , a measuring step S200 , and a determining step S300 .

First, the voltage applying unit 410 is electrically connected to each external specimen member 310 and each internal specimen member 320 through each of the above-described external conductive wire parts 332 and each internal conductive wire part 352 . can

In addition, the voltage applying unit 410 may perform the initial value setting step S100 of applying a predetermined reference voltage between each external specimen member 310 and each internal specimen member 320 .

Next, the detection unit 420 may perform the measurement step ( S200 ) of detecting a change state of each reference voltage corresponding to the corrosion progress of each external specimen member 310 in real time.

For example, if it is assumed that the reference voltage is 5V, when corrosion does not proceed to the external specimen member 310 , the resistance between the external specimen member 310 and the inner specimen member 320 is close to infinity, and the reference voltage at this time may represent a value converging to 5V.

Thereafter, when corrosion proceeds on the external specimen member 310 by various corrosion-inducing factors inside the scrubber, at least a portion of the external specimen member 310 melts or breaks, and moisture and various exhaust gases are introduced into these corrosion-damaged parts. The resistance between the terminals is reduced due to the inflow of light. As such, when the physical and electrical resistance of the external specimen member 310 itself is reduced due to corrosion, the reference voltage is reduced to less than 5V in response thereto.

Then, the operation unit 430 may perform the determination step (S300) of determining the corrosion state inside the scrubber by comprehensively determining the change state of each reference voltage described above.

In this case, the distribution and flow state of the corrosion-inducing factors inside the scrubber may not be uniform, and thus, the result of the corrosion determination may be derived differently depending on the measurement location.

However, as described above, since a plurality of external specimen members 310 are provided at mutually different positions, data collection of various angles corresponding to the distribution and flow state of corrosion-inducing factors can be performed accordingly. In addition, since a plurality of result values measured at different locations can be comprehensively judged by the monitoring unit 400, the average and substantial corrosion state in the scrubber, taking into account the distribution and flow state of corrosion-inducing factors, is can be judged.

In addition, the thickness of each external specimen member 310 may be set in various ranges in response to the distribution of corrosion-inducing factors inside the scrubber. As the measurement parameters are diversified, such as by varying the thickness of the measurement specimens, a monitoring result in which the distribution and flow state of corrosion-inducing factors are considered more diversely can be calculated.

In addition, the operation unit 430 may transmit the monitoring data to the external central management unit 10 through the network (1). In this case, the network 1 may be understood as a means for generalizing wired Internet computer networks, long-term evolution, Wi-Fi, Bluetooth, Internet of Things means, artificial satellites, and various other wired/wireless communication means not mentioned.

However, preferably, wireless communication means in which the use of corrosion-sensitive conductors and the like can be minimized may be selected as the network 1 .

In addition, the central management unit 10 may be provided in various locations, such as a ship in which a scrubber for monitoring the corrosion state is installed, a separate external place communicating with the ship, and the like. In addition, the central management unit 10 may be applied to a laptop, a desktop, a PDA, a smart device, and other various arithmetic processing means.

Next, Figure 10 is a cross-sectional view showing a corrosion detection device of the marine scrubber according to another embodiment of the present invention.

The corrosion detection device of the marine scrubber according to another embodiment of the present invention is the same as the above-described embodiment, but has a difference in the coupling relationship between the external specimen member 310 and the module case unit 200 .

More specifically, referring further to FIG. 10 , a specimen-side press-in groove 314 having a recessed structure may be formed in a region corresponding to the above-described specimen-side coupling reinforcing groove 313 in the external specimen member 310 .

In addition, the above-described case-side insertion part 230 may be formed with a case-side protrusion 240 protruding along the outer circumferential direction and engageable in the press-fitting groove 314 on the specimen side. At this time, in the process in which the case-side insertion part 230 is inserted into the external specimen member 310 , interference may occur due to a difference in diameter between the inner diameter of the specimen-side protrusion 311 and the outer diameter of the case-side protrusion 240 side. can

However, when the case-side insertion part 230 is elastically pressed toward the concentric axis of the case body 220 , the case-side protrusion 240 also moves in the same direction at the same time. At this time, since the above-described moving direction of the case-side protrusion 240 corresponds to a direction in which the inner diameter of the specimen-side protrusion 311 is reduced, the case-side protrusion 240 enters the inner section of the specimen-side protrusion 311 . Then, it may be moved to face the press-fitting groove 314 on the specimen side.

Next, when the compression pressing force on the case-side insertion part 230 side is released and an elastic restoration action occurs, the case-side protrusion 240 is a specimen side press-in groove in the elastic restoration direction of the case-side insertion part 230 ( 314) in the direction of the outer diameter. Thus, a type of forced press-fitting fastening structure in which the case-side protrusion 240 is elastically strongly adhered to the specimen-side press-in groove 314 can be implemented.

By providing the above-described forced press-fitting fastening structure, when the replacement of each external specimen member 310 is performed, the use of separate fastening means and fasteners or chemical bonding means such as bolting or welding is minimized, and convenient replaceability is achieved. The advantages provided will arise.

In particular, considering that the external specimen member 310 is a part scheduled to be replaced frequently because it is directly exposed to corrosion-inducing factors, it can be understood that the above-described forced press-fitting structure has a fairly effective effect.

At this time, the above-described specimen coupling portion 260 and related components may not be applied.

Alternatively, the above-described specimen coupling portion 260 and related components may be utilized for coupling between the support cover 210 and the case body 220 . In this case, the distal end of the specimen coupling portion 260 may not be exposed to the outside of the case body 220 , and the specimen side coupling groove 312 may not be formed.

Alternatively, the above-described specimen coupling unit 260 and related components may be applied similarly to the other embodiments described above. In this case, between the external specimen member 310 and the case body 220, in addition to the coupling force provided by the specimen coupling unit 260, an additional coupling force according to the above-described forced press-fitting principle may be provided.

As described above, the present invention has a main technical idea to provide an apparatus for detecting corrosion of a scrubber for a marine vessel, and the embodiment described above with reference to the drawings is only one embodiment, and the scope of the present invention is a patent In addition to the claims, it will also extend to equivalent embodiments that may exist in various ways.
