Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sliding type SCR system for a ship or onshore plant,

The present invention relates to an SCR system for reducing nitrogen oxides (NOx) in an exhaust gas, and more particularly, to an SCR system for purifying exhaust gas generated from a ship, maximizing the life of a reactor and maximizing space utilization .

Nitrogen oxides and sulfur oxides in exhaust gases from vessels are representative air pollutants subject to emission regulation from the International Maritime Organization (IMO), the United Nations (UN) affiliate.

Nitrogen oxides are regulated below 2 g / kwh in 2016, the time when Tier III enters into force, and sulfur emissions will be regulated below 1% in SECA (sulfur emission control area) in July 2010.

Nitrogen oxides refer to NO, NO2, NO3, N2O, N2O3, N2O4 and N2O5, but most nitrogen oxides are NO and NO2. Sulfur oxides are mainly SO2 in which sulfur components contained in fuels such as coal and petroleum are oxidized in the combustion process.

On the other hand, for ships operating in a specific area (ECA: Emission Control Area) that meet enhanced environmental regulations or have enhanced environmental regulations, it is necessary to ensure that exhaust gases (especially during operation of a ship engine or boiler It is necessary to provide a device for reducing nitrogen oxides in the exhaust gas.

The NOx reduction method is classified into a pretreatment method for controlling the combustion method and a post-treatment method for reducing the exhaust gas. The selective catalytic reduction (SCR) and the selective non-catalytic reduction (SNCR) , Selective non-catalytic reduction) are mainly used.

The SCR technology removes nitrogen oxides from nitrogen and water by passing the exhaust gas between 200 ° C and 450 ° C through the catalyst bed together with a reducing agent. SNCR, on the other hand, is a technology for removing nitrogen oxides by injecting a reducing agent directly into the exhaust gas above 800 ° C.

Since the exhaust gas of the ship is discharged at a temperature of 300 ° C. to 450 ° C., the SCR system is mainly installed as a nitrogen oxide reduction apparatus. Ammonia or urea solution is mainly used as a reducing agent used in the SCR system.

The conventional SCR system is composed of a reactor 22, a reactor housing 21, a bypass damper 34 and a bypass line 33 as shown in Fig.

The reactor housing 21 accommodates a plurality of reactors 22 containing catalyst therein which is drawn into the reactor housing 21 through the inlet line 31 and passes through the reactor 22, NOx in the exhaust gas is reduced by the selective catalytic reduction reaction and is discharged through the exhaust line 32. [

This conventional SCR system is limited in the lifetime (5 to 7 years) of the reactor 22 depending on the passage time of the exhaust gas, the amount of passage, the type of the fuel oil, The bypass line 33 and the bypass damper 34 are installed so that the exhaust gas is discharged without passing through the reactor 22 when the ECA is not operated for extending the service life of the exhaust gas.

However, in the conventional SCR system, a separate additional exhaust gas line called a bypass line 33 must be installed. This installation work is difficult due to a limited space such as an engine room or an engine casing of the ship, The space utilization is reduced and the maintenance work of the reactor 22 becomes inconvenient.

It is an object of the present invention to solve the above-mentioned problems of the prior art, and to provide an SCR system in which the reactor is easily detachable, thereby enhancing the life of the reactor, enhancing the system redundancy and reducing the soot blowing. And it is an object of the present invention to provide a sliding type SCR system for an elevated ship or onshore plant.

According to an aspect of the present invention, there is provided an SCR system for purifying exhaust gas discharged from a ship or an onshore plant. The SCR system includes an exhaust gas inlet line for introducing exhaust gas into an SCR system, A reactor housing (210) positioned between the exhaust gas discharge line (320) for discharging the exhaust gas to the exhaust gas outlet line (320); And at least one reactor (220) accommodated in the reactor housing (210) and containing at least one catalyst layer for reducing NOx in the exhaust gas in contact with exhaust gas passing through the reactor housing (210) And a reactor moving means (235) for moving the reactor (220) to a position deviated from the reactor housing (210).

The reactor 220 is installed at least one way in the left-right direction or the vertical direction of the reactor housing 210.

The reactor moving means 235 includes a sliding guide portion 235 installed inside the reactor housing 210 to receive the reactors 250, respectively. And a reactor frame 230 installed outside each of the reactors 220 so that each of the reactors 220 slides through the sliding guide part 235 and moves to a position deviating from the reactor housing 210. [ .

The reactor housing 210 is provided with an opening for allowing the reactor 220 to move to a position away from the reactor housing 210; And a quick coupling cover (240) for opening and closing the opening, wherein the quick coupling cover (240) is installed corresponding to each of the reactor frames (230) and is individually opened and closed, and the reactor frame Each of which is separate from the reactor housing 210 through an opening in which the corresponding quick-coupling cover 240 is located.

The quick coupling cover 240 is connected to the reactor frame 230 to move the quick coupling cover 240 to a position deviated from the reactor housing 210 while opening and closing the quick coupling cover 240 The reactor frame 230 is also moved to a position deviating from the reactor housing 210.

The quick coupling cover 240 may further include fastening means for fastening the quick coupling covers 240 to each other, wherein when the fastening means separates each of the quick coupling covers 240, And the quick-coupling cover 240 is configured to open and close the opening as a whole when the quick-coupling cover 240 is fastened.

According to another aspect of the present invention, there is provided an SCR system for purifying exhaust gas discharged from a ship or an onshore plant, comprising: at least one reactor 220 (at least one reactor 220) for containing at least one catalyst layer for reducing NOx in the exhaust gas in contact with the exhaust gas; ) Is installed in an exhaust gas line through which the exhaust gas passes, and the reactor (220) is movable to a position deviated from the exhaust gas line, wherein a sliding type SCR system for a ship or onshore plant is provided .

When a plurality of the reactors 220 are installed, each of the reactors 220 can be moved to a position deviating from the exhaust gas line, individually or separately.

According to the present invention, by constructing the reactor of the SCR system so as to be removable, the bypass line can be removed and the space utilization of the ship can be enhanced.

In addition, it is possible to extend the lifetime of the reactor and make the maintenance work easier by making the reactor away from the exhaust gas line when operating the reactor or operating the area where the SCR is not needed.

In addition, since the amount of soot (soot) contained in the exhaust gas is reduced in the SCR catalyst layer, it is not necessary to use the low-density catalyst layer in the SCR system, thereby preventing the volume of the SCR system from becoming large, .

Also, since the amount of soot accumulated on the SCR catalyst layer is reduced, the number of times of soot blowing for removing the soot is reduced to reduce the consumption amount of the compressed air, thereby increasing the energy efficiency.

In addition, since the reactor can be installed and removed for each layer, only the reactor requiring maintenance work can be repaired, thereby prolonging the life of the reactor.

In addition, even if some reactors fail, it is possible to repair the failed reactors while operating other reactors, thereby enhancing the redundancy of the reactors.

In addition, the SCR system can be manufactured at a lower cost.

2 is a view schematically showing an SCR system according to the present invention.

Ships used in this specification include marine floating structures that may float on the sea, as well as vessels of general significance with propulsion engines.

As shown in FIG. 2, the sliding type SCR system for a ship or onshore plant according to the present invention is an SCR system for purifying and discharging exhaust gas discharged from a ship or onshore plant, Wherein at least one reactor (220) containing at least one catalyst layer for reducing NOx is installed in an exhaust gas line through which the exhaust gas passes, wherein the reactor (220) is movable to a position deviated from the exhaust gas line, and the reactor The reactors 220 can be moved to a position deviating from the exhaust gas line, individually or separately.

That is, one or more reactors 220, each of which is composed of one or more catalyst layers for reducing NOx, are installed in an exhaust gas line through which exhaust gas flows, and each of the reactors 220 includes a reactor 220, To the location of the present invention.

The sliding type SCR system for a ship or onshore plant according to the present invention may include a reactor housing 210, a reactor 220, and a reactor moving means 235, for example.

The reactor housing 210 is installed in the exhaust gas line, and is located between an exhaust gas inlet line 310 for exhausting the exhaust gas to the SCR system and an exhaust gas exhaust line 320 for exhausting the exhaust gas to the outside.

The exhaust gas may be various types of equipment for discharging the exhaust gas by combustion in a ship such as a propulsion engine of a ship or an engine for other purposes or a boiler used in a ship and a reactor housing 210 and a reactor 220 accommodated in the reactor housing 210 to reduce NOx in the exhaust gas.

The reactor 220 may contain one or more catalyst layers and may be accommodated in the interior of the reactor housing 210 so that the reactor 220 accommodated in the reactor housing 210 is exhausted through the reactor housing 210 And is in contact with the gas to reduce NOx in the exhaust gas.

The reactor 220 may contain two or more catalysts having different activation temperatures, and may further include a catalyst for reducing other components in addition to the NOx reduction catalyst.

One or more of the reactors 220 may be installed in the left or right direction or the vertical direction of the reactor housing 210 so that the reactors 220 can pass through the exhaust gas, 220 can be moved to avoid contact with the exhaust gas.

2, in order to efficiently remove NOx, the reactor 220 installed in the reactor housing 210 with at least one catalyst layer therein is provided with a plurality of reactors (not shown) for passing the exhaust gas flowing upward, One or more can be installed in the vertical direction.

When the exhaust gas flows in the left and right direction, one or more reactors 220 may be installed in the left and right directions of the reactor housing 210.

The reactor 220 provided in at least one direction in each direction (the up-and-down direction in FIG. 2) forms a layer. In FIG. 2, the reactor layer 221 having three stages is shown.

It is desirable that the reactor 220 can perform maintenance and repair operations such that only the reactor 220 requiring maintenance work is deviated from the reactor housing 210 in order to facilitate the maintenance work. Therefore, the plurality of reactors 220 Is installed inside the reactor housing 210.

The reactor moving means 235 allows the reactor 220 to move to a position away from the reactor housing 210.

By doing so, only the reactor 220 requiring maintenance work is moved away from the reactor housing 210 to carry out the maintenance and repair work, and the normal operation of the reactor 220 is continued so that the redundancy of the SCR system is maintained And to strengthen it.

When the ship passes through a region where the emission regulation of NOx is not strict, or when the regular route of the ship is an area where the emission regulation of NOx is not strict, the reactor 220 is moved away from the reactor housing 210, So that the service life (life) of the reactor 220 is prolonged.

In the conventional SCR system, soot (soot) included in the exhaust gas is accumulated in the SCR catalyst layer and the catalyst layer is frequently clogged. Therefore, a low density catalyst of 25-30 cpi (cell per inch) can not be installed in the SCR system This increases the volume of the SCR system to reduce the space utilization of the limited vessel and increases the number of soot blowing operations for removing the soot. The SCR system according to the present invention has an unnecessary reactor 220 So that the conventional problems can be solved.

In other words, by preventing frequent use of the unnecessary reactors 220, the amount of accumulated soot in the reactor 220 can be reduced to reduce the use of the low-density catalyst layer. As a result, the space utilization of the vessel can be increased, the number of times of soot blowing by which the compressed air is injected into the reactor 220 to remove the soot can be reduced so that the consumption of compressed air can be reduced, and as a result, the energy efficiency can be increased.

In addition, the bypass line can be installed while having these effects, thereby maximizing the space utilization of the ship.

At this time, since the exhaust gas is at a high temperature, a moving device 235 for automatically releasing the reactor 220 from the reactor housing 210, for example, a driving device such as a motor, is installed to ensure worker convenience and safety can do.

The movement of the reactor 220 is preferably carried out when the engine is stopped in consideration of the safety of the operator.

At this time, leakage of exhaust gas from the exhaust gas housing 210 may occur when the reactor 220 is removed from the reactor housing 210 because the reactor 220 is connected to the reactor housing 210 to maintain and repair the reactor 220. [ The cover 410 may be formed in a space deviating from the cover 210 to prevent leakage of the exhaust gas.

Such a task would be possible during the operation of the engine since there is no danger of high temperature exhaust gas leakage.

The reactor housing 210 is also sealed by completely separating the reactor 220 from the reactor housing 210 and closing the opening through which the reactor 220 is separated from the reactor housing 210 with a separate cover .

However, this operation is preferably performed when the engine is stopped, because high temperature exhaust gas may leak during the sealing operation when the engine is running and the operator may be hurt thereby.

The reactor moving means 235 includes a sliding guide portion 235 and a reactor frame 230.

The sliding guide portion 235 is installed inside the reactor housing 210 so that the reactor 220 can be seated inside the reactor housing 210.

The reactor frame 230 is installed outside the reactor 220 to accommodate the reactor 220 so that the reactor 220 can stably be seated on the sliding guide portion 235. The reactor 220 is mounted on the reactor frame 230 So as to be displaced from the reactor housing 210 while being slid through the sliding guide portion 235.

The sliding guide portion 235 is formed in a rail shape so that the reactor frame 230 can be slid. The roller frame 230 is provided with a roller at a portion contacting the sliding guide portion 235, As described above, the motor can be automatically attached to the sliding guide portion 235 so that the roller can slide automatically.

The reactor housing 210 of the SCR system according to the present invention may further include an opening for allowing the reactor 220 to move to a position deviated from the reactor housing 210 and a quick coupling cover 240 for opening and closing the opening have.

The quick coupling cover 240 is provided corresponding to each of the reactor frames 230 and is individually opened and closed so that each of the reactor frames 230 is individually accommodated in the reactor housing 230 through the opening in which the corresponding quick coupling cover 240 is located. Lt; RTI ID = 0.0 > 210 < / RTI >

The quick coupling cover 240 is connected to the reactor frame 230 to move the quick coupling cover 240 to a position deviated from the reactor housing 210 while opening and closing the opening, To move to a position deviating from the first position (210).

With this arrangement, the reactor 220 according to the present invention is able to separate each reactor 220 from the reactor housing 210 in a drawer form from the reactor housing 210.

At this time, it is possible to further include fastening means (not shown) for fastening the quick-coupling covers 240 to each other. When the fastening means separates the quick-coupling covers 240, 240 are individually opened and closed. When the quick-coupling covers 240 are fastened, the quick-coupling cover 240 opens and closes the entire opening.

When the reactor 220 needs to be totally separated from the reactor housing 210 by the fastening means, the quick coupling covers 240 are fastened by the fastening means so that the reactor frames 220 accommodating the reactors 220 230 may be quickly and collectively removed from the reactor housing 210 and if the reactor 220 needs to escape the reactor housing 210 separately, the fastening means may be separated to accommodate the reactors 220, Thereby causing the reactor frame 230, which is in turn, to separate from the reactor housing 210.

Hereinafter, the operation of the sliding type SCR system for a ship or onshore plant according to the present invention will be described.

When a ship equipped with the SCR system according to the present invention is operated in a specific area (ECA: Emission Control Area) having enhanced environmental regulations, the reactor 220 is accommodated in the reactor housing 210 so as to be in contact with the exhaust gas So as to purify the exhaust gas.

However, when passing through an area without enhanced environmental regulations, the reactor 220 is moved to a position away from the reactor housing 210 in order to extend the lifetime of the reactor 220, thereby protecting the reactor 220.

The reactor 220 may move each reactor separately from the reactor housing 210 in the same manner as opening and closing the drawer and may move the entire reactor 220 simultaneously, .

Thus, the SCR system according to the present invention can achieve not only the protection of the reactor 220 but also the removal of the bypass line, thereby achieving the various effects described above.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. will be.
