Description

[Technical field]

[0001] The present invention relates to a hanging support structure between a large SCR cartridge integrated with a dry reaction dust collector of an incineration and combustion furnace and a support frame, in which large SCR cartridges are hung in one row (vertical) and two columns (horizontal) in a hanging support type on a support frame fixed to the inner wall of a housing, and connected and supported by connecting members, thereby significantly improving reaction efficiency. [Background technology]

[0002] Generally, exhaust gas discharged from incinerators and combustion furnaces contains various harmful substances, namely, NOx, SOx, HCl, dioxins, and fly ash.

[0003] The exhaust gas containing the above-mentioned harmful substances is passed through an air pollution control facility to remove the harmful substances before being released into the atmosphere. In order to remove various harmful substances during this process, air pollution control facilities, which are harmful substance removal facilities, are installed according to the type of harmful substance.

[0004] As a conventional dust collecting device provided for removing the above-mentioned harmful substances, a device disclosed in Patent Document 1 has been proposed.

[0005] As shown in FIG. 19, the dust collecting device 70 of Patent Document 1 includes a rectangular housing 74, a casing cover 75 and a hopper 76 installed at the upper and lower ends of the housing 74, SCR cartridges 73 mounted one above the other inside the housing 74, an air nozzle 77, and a back filter 78.

[0006] The SCR cartridge 73 is in the form of a panel, and contains a pellet-shaped catalyst inside that reacts at low temperatures (145~180℃). Selective catalytic reduction (SCR) is a technology that removes nitrogen oxides (NOx) emitted from the combustion of fossil fuels and waste materials. It is a catalyst that reacts ammonia gas (NH3) with NOx and reduces it to N2 and H2O by selectively using a method such as spraying urea water from the SNCR to perform a primary reaction and reusing the unreacted ammonia gas, or adding additional ammonia water as an SCR catalyst to the exhaust gas flowing in to supply the necessary reaction chemicals.

[0007] The chamber between the casing cover 75 and the SCR cartridge 70 is the clean zone 71 .

[0008] The clean zone 71 is a chamber where unpurified exhaust gas enters a hopper 76 and collects purified gas that has passed through a back filter 78 and an SCR cartridge 73 .

[0009] The SCR cartridge 73 is placed on a support frame 72 , which is an L-shaped steel member fixed to an inner wall 74 a of a housing 74 .

[0010] Typically, the SCR cartridge 73 includes a small cartridge weighing approximately 80 kg and a large cartridge weighing approximately 250 to 350 kg.

[0011] Four small cartridges are placed on a support frame 72 in a square shape installed in one chamber, but if there are multiple chambers at a site, the small cartridges are arranged in a checkerboard pattern along the horizontal or vertical direction.

[0012] That is, a plurality of or more miniature cartridges are arranged in both the horizontal and vertical directions within one chamber.

[0013] On the other hand, two large cartridges are placed on the square-shaped support frame 72 in one chamber, but if there are multiple chambers depending on the site, the large cartridges are arranged in a ladder-like manner along the horizontal direction.

[0014] That is, in one chamber, a plurality of large cartridges are arranged in the horizontal direction, but only one in the vertical direction.

[0015] Therefore, small SCR cartridges and large SCR cartridges are classified as being arranged in a plurality or more units in the horizontal direction, but in a plurality or more units in the vertical direction, while only one large cartridge is arranged.

[0016] Such a conventional SCR cartridge 73 is placed on the support frame 72 by its own weight alone, and when it moves and shakes due to the gas that has passed through the back filter 78, the catalyst inside is biased to one side, and gas that has not reacted with the catalyst enters the clean zone 71 as it is, reducing the reaction efficiency.

[0017] Furthermore, unreacted gas may escape into the gap between the SCR cartridge 73 and the support frame 72 due to manufacturing errors, thermal deformation (distortion) during use, vibration during operation, and the like.

[0018] Therefore, gas that has not passed through the SCR cartridge 73 enters the clean zone 71 as is, significantly reducing the reaction efficiency. [Prior art documents] [Patent documents]

[0019] [Patent Document 1] Korean Patent Publication No. 10-0769667 Summary of the Invention [Problem to be solved by the invention]

[0020] The present invention has been devised to solve the above-mentioned problems, and has an object to provide a hanging support structure between a large SCR cartridge integrated with a dry reaction dust collector of an incineration and combustion furnace and a support frame, in which multiple large SCR cartridges are hung in a hanging manner on a support frame fixed to the inner wall of a housing and connected and supported by connecting members, thereby significantly improving reaction efficiency. [Means for solving the problem]

[0021] In order to achieve the above-mentioned object, the hanging support structure between a large SCR cartridge integrated with a dry reactive dust collector of an incineration and combustion furnace and a support frame of the present invention includes a support frame fixed to the inner wall of a housing between a casing cover and a back filter, a plurality of panel-shaped small SCR cartridges arranged horizontally along the left-right (horizontal) and front-back (vertical) directions on the upper surface of the support frame, and a connecting member that connects and supports the small SCR cartridges to the support frame, the support frame including front-back, left-right and right frame bars fixed in a strip shape along the periphery of the inner wall, and vertical and horizontal cross bars fixed in a cross shape to the front-back, left-right and right frame bars, the small SCR cartridges are supported by having the lower surface of their edges placed on the upper surface of the support frame, and the connecting member includes connecting lugs fixed to the upper surface of the support frame at predetermined intervals, and connecting parts that are connected to the connecting lugs to support the small SCR cartridges by applying pressure to the support frame. Effect of the Invention

[0022] The present invention has the following advantages.

[0023] Since the wing parts installed on the periphery of the large SCR cartridge body are simply hung on the support frame, the large SCR cartridge is suitable for cases where investment costs and ground space due to a small site are limited when improving existing facilities by using the top of the back filter in most cases. In addition, since it is a large-scale production, it is also preferable to reduce manufacturing labor costs and material costs, and compared to the small SCR cartridge that requires a lot of sealing packing, the catalytic reaction efficiency is good even with a small sealed structure, so design costs can be reduced.

[0024] In addition, by forming a support frame using U-shaped steel beams in a concave groove shape and fastening a bolt to the female thread fixed inside this support frame, it is possible to easily apply pressure to the pressure plate and increase the connecting and supporting force of the large SCR cartridge.

[0025] Meanwhile, the pressure plate is inserted into the connecting lug fixed inside the support frame, and the split pin is inserted into the connecting hole of the connecting lug to complete the connection, so that multiple pressure plates are evenly pressurized and multiple large SCR cartridges are well maintained horizontally.

[0026] Furthermore, the pair of pins of the split pin spread apart toward the tip, and the upper surfaces of the pair of pins form an inclined surface that becomes thinner toward the tip. Therefore, when the split pin is inserted into the connecting hole, the pair of pins apply pressure to the connecting hole, making it difficult for it to come out. Furthermore, the further the inclined surface is inserted, the more the pins act as a wedge, significantly improving the sealing efficiency due to pressure between the support frame and the large SCR cartridge.

[0027] In addition, a packing is further installed between the vertical bar of the support frame and the wing of the large SCR cartridge, which further improves the sealing efficiency between the support frame and the large SCR cartridge.

[0028] In addition, by further fixing pressure plate support pieces facing the connecting lugs to the outer periphery of the front, rear, left and right frame bars, a uniform pressure plate can be formed overall. [Brief description of the drawings]

[0030] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this embodiment, the same reference numerals are used to designate the same parts as in the conventional embodiment, and detailed description thereof will be omitted.

[0031] In addition, in the present embodiment, as shown in FIG. 1 to FIG. 3, the left-right direction indicates a horizontal or row, and the front-back direction indicates a vertical or column.

[0033] 1 to 3 show a dust collector module in which four unit dust collectors are arranged in the first, second, third and fourth quadrants.

[0034] Therefore, the following description will be given based on the case where the dust collector is located in the first or fourth quadrant.

[0035] As shown in FIGS. 1 to 3, the dust collector 100 for an incineration and combustion furnace according to this embodiment includes a rectangular housing 110, a casing cover 130 and a hopper 150 installed at the upper and lower ends of the housing 110, a plurality of large SCR cartridges 200 mounted on the upper inside part of the housing 110, an air nozzle 170, and a back filter 190, a support frame 300 on which the plurality of large SCR cartridges 200 are placed and supported while being fixed to the inner wall of the housing 110, and a connecting member 500 for connecting and supporting the large SCR cartridges 200 to the support frame 300.

[0036] Moreover, the casing cover 130 is fixed to the upper side of the housing 110 .

[0037] Additionally, a clean zone 140 is formed in the chamber between the casing cover 130 and the large SCR cartridge 200 .

[0038] As shown in FIGS. 4 to 7, the large SCR cartridge 200 includes a large SCR cartridge body 210 made of a stainless steel plate, and wings 220 fixed along the side of the large SCR cartridge body 210.

[0039] The large SCR cartridge body 210 is a panel-like rectangular cylinder in which a catalyst is placed.

[0040] The wing portion 220 is supported by being hung on the upper surface of the support frame 300 .

[0041] Wing portion 220 includes front and rear wing portions 221 formed along the front and rear side surfaces, and left and right wing portions 223 formed along the left and right side surfaces.

[0042] As shown in Figures 10, 12, and 13, the front, rear, left, and right wings 221, 223 include front, rear, left, and right horizontal wings 221a, 223a, one end of which runs along the periphery of the side panel 215, and front, rear, left, and right vertical wings 221b, 223b extending downward from the other ends of the front, rear, left, and right horizontal wings 221a, 223a.

[0043] The insides of the front, rear, left and right horizontal blades 221a, 223a and the front, rear, left and right vertical blades 221b, 223b function as grooves into which the packing part 600 described below is inserted and attached.

[0044] Of course, if the packing 600 is not provided, the large SCR cartridge body 200 would be supported by having the front, rear, left and right horizontal wings 221 a and 223 a hung on the support frame 300 .

[0045] Since such a wing portion 220 only needs to be hung on a support frame, the large SCR cartridge 200 is suitable when improving existing facilities by mostly using the top of a back filter, and when there are limitations on investment costs and ground space due to a small site.

[0046] In addition, since it is a large-scale production, it is also favorable for reducing manufacturing labor costs and material costs. In contrast to small SCR cartridges that require a lot of sealing packing, the catalytic reaction efficiency is good even with a small sealed structure, so design costs can also be reduced.

[0047] The large SCR cartridge body 210 is composed of upper and lower porous plates 211 and 213 which define the outer shape, and a side plate 215. The side plate 215 is a steel section having a U-shaped cross section.

[0048] The upper and lower perforated plates 211, 213 and the side plate 215 are joined together by riveting.

[0049] The positions of the holes in the upper and lower perforated plates 221 and 213 are uniformly distributed across the entire top and bottom in accordance with the given conditions of the site and minimization of non-reactive areas, or the holes are distributed toward the center of the upper perforated plate 211 and toward the left and right sides of the lower perforated plate 213, or the opposite positions are used.

[0050] Two lifting lugs 240 are fixed to each of the upper and lower surfaces of the upper porous plate 211 .

[0051] The lifting lugs 240 are placed one above the other so that the catalyst can be filled inside them in an upright position.

[0052] In particular, the large SCR cartridge body 210 is made up of a single housing with its interior divided into multiple sections.

[0053] In order to divide the inside into multiple parts, a U-shaped steel member 250 in the form of a dividing rib like the side plate 215 is further fixed inside the upper and lower perforated plates 211 and 213 as shown in Figs.

[0054] The divided rib-like U-shaped steel member 250 serves as a reinforcing member for suppressing tensile deformation of the upper and lower porous plates 211, 213 and torsional deformation of the large SCR cartridge body 210 during lifting.

[0055] The dividing rib-like U-shaped steel section 250 divides the tube in which the catalyst is placed into front, rear, left and right sections, so that openings 231 are formed on the front and rear surfaces of the side plate 215, which is a U-shaped steel section, as shown in Figures 5 and 6. The openings 231 are opened and closed by a catalyst filling cover plate 233.

[0056] The catalyst loading cover plate 233 is fastened to the front and rear surfaces of the side plate 215 with countersunk bolts.

[0057] In this case, the lower ends of the front and rear vertical blades 221b having the opening 231 as shown in Figure 10 are positioned higher than the lower ends of the left and right vertical blades 223b in Figures 12 and 13 (see Figure 6). This is to prevent the front and rear vertical blades 221b from hiding the opening 231, making it easier to insert and remove the catalyst and to attach and remove the cover plate 223.

[0058] Two of these large SCR cartridges 200 are placed on a support frame 300 shown in FIG.

[0059] Of course, the support frame 300 can be expanded left and right as much as desired.

[0060] For example, as shown in FIG. 3, if the large SCR cartridges 200 are arranged in one row and four columns, the support frame 300 will be extended further to the left and right.

[0061] The support frame 300 is a steel member having a U-shaped cross section, and is fixed to the inner wall of the housing 110 .

[0062] That is, the support frame 300 includes front, rear, left and right frame bars 310, 320, 330, 340 fixed in a strip shape along the periphery of the inner wall, and a vertical cross bar 350 fixed inside the front and rear frame bars 310, 320, as shown in FIG.

[0063] In the space of the support frame 300 arranged in this manner, two large SCR cartridge bodies 210, indicated by dotted lines, are arranged and supported on the upper surface of the support frame 300 to form a suspended support type structure.

[0064] Here, as shown in FIG. 1 and FIG. 2, a support frame 300 is supported on the support portion for the back filter 190. As shown in FIG.

[0065] As shown in Figures 10, 12, and 13, the support frame 300 is a concave-cross-section steel structure consisting of a first vertical bar 301, a second vertical bar 303, and a connecting bar 305 connecting the lower sides of the first and second vertical bars 301, 303.

[0066] The first vertical bars 301 of the front, rear, left and right frame bars 310, 320, 330, 340 are fixed to the inner wall of the housing 110 as shown in FIGS.

[0067] The wing portion 220 is supported by being hung on the second vertical bars of the front, rear, left and right frame bars 310, 320, 330, 340 and the first and second vertical bars 301, 303 of the vertical cross bar 350.

[0068] As shown in Figures 10, 12, and 13, the connecting member 500 according to one modified example includes a female screw 510 inserted into the bottom of the connecting bar 305, a pressure plate 530a or 530b placed on the large SCR cartridge 200, and a bolt 550 fastened to the female screw 510 so that the pressure plate 530a or 530b presses and supports the large SCR cartridge 200 to the support frame 300.

[0069] Bolt 550 is an eye bolt.

[0070] The pressure plates 530a and 530b include a first pressure plate 530a that is hung on the large SCR cartridge 200 between the vertical cross bars 350 as shown in FIG. 13 and pressurizes and supports the large SCR cartridge 200 hung on the front, rear, left and right frame bars 310, 320, 330 and 340.

[0071] The first pressure plate 530a is a first horizontal plate, and applies the same pressure to the left and right large SCR cartridges 200.

[0072] The second pressure plate 530b includes a second horizontal plate 531b and a second vertical plate 533b bent from the second horizontal plate 531b towards the connecting bar 305, as shown in FIGS.

[0073] The second horizontal plate 531b is placed on the upper surfaces of the side plate 215 and the front and rear wing portions 221 of the U-shaped steel structure, and has an insertion hole into which the bolt 550 is inserted.

[0074] The second horizontal plate 533b is lowered to the inside of the support frame 300, and when its tip hits the bottom of the connecting bar 305, it is not fastened any further.

[0075] In addition, packing 600 is further installed between the first and second vertical bars 301, 303 and the wing portion 220, which prevents unreacted gas from escaping into the gap, thereby improving reaction efficiency.

[0076] Another alternative coupling member 500' is shown in Figures 15-17.

[0077] The connecting member 500' includes connecting lugs 510' welded to the upper surface of the support frame 300 at predetermined intervals, a pressure plate 530' placed on the upper surface of the large SCR cartridge 200 on the connecting lugs 510', and split pins 540' inserted into connecting holes 511' of the connecting lugs 510' to connect the pressure plate 530' while applying pressure thereto.

[0078] The pressure plate 530' is made of a rectangular plate as shown in FIG.

[0079] As shown in FIG. 18, the split pin 540' includes a head 541' that is bent into an almost oval shape, and a pair of pins 543' that extend from both sides of the head 541' toward the tip and widen from each other.

[0080] In particular, the split pin 540' is a pin formed by bending a strip-shaped plate.

[0081] The upper surfaces of the pair of pins 543' are formed with inclined surfaces 545' whose thickness gradually decreases toward the tips.

[0082] Such an inclined surface 545' has a wedge shape when viewed from the front as shown in FIG.

[0083] Therefore, when the pair of pins 543' of the split pin 540' is contracted and then inserted into the coupling hole 511', the inclined surface 545' pushes the pressure plate 530' downward as it advances, providing excellent coupling force. In particular, the contact sealing force between the large SCR cartridge 200 and the support frame 300 can be improved, significantly increasing reaction efficiency.

[0084] In addition, when the pair of pins 543' spreading out in a V-shape are inserted into the coupling holes 511', a repulsive force acts on them to spread out, which further prevents any separation.

[0085] The pressure plate 530' described above is configured to couple the large SCR cartridge 200 with the vertical crossbar 350 of FIG. 14 sandwiched therebetween.

[0086] Meanwhile, a coupling member 500' of another modified example shown in FIGS. 15 and 16 is configured for coupling between the large SCR cartridge 200 and the front, rear, left and right frame bars 310, 320, 330, 340. As shown in FIG.

[0087] Therefore, the connecting member 500' of another modified example shown in FIGS. 15 and 16 is different in that, as shown in FIG. 17, the front, rear, left and right frame bars 310, 320, 330, 340 are provided with pressure plate support pieces 550'.

[0088] In other words, the connecting member 500' of another modified example shown in Figures 15 and 16 includes connecting lugs 510' installed at predetermined intervals on the upper surfaces of the front, rear, left and right frame bars 310, 320, 330 and 340, pressure plate support pieces 550' facing the outer contours of the connecting lugs 510', a pressure plate 530' inserted into the connecting lugs 510' and placed on the upper surfaces of the large SCR cartridge 200 and the pressure plate support pieces 550', and a split pin 540' inserted into a connecting hole 511' of the connecting lug 510'.

[0089] Therefore, when the split pin 540' is coupled, the pressure plate 530' uniformly presses the upper surfaces of the large SCR cartridge 200 and the pressure plate support piece 550', thereby improving the coupling force of the large SCR cartridge 200.

[0090] As described above, the present invention has been described with reference to a preferred embodiment, but those skilled in the art may implement the present invention in various modified and altered forms without departing from the spirit and scope of the present invention as set forth in the claims below.
