Description

  The present invention relates to a deodorizing filter and a deodorizing apparatus. For example, the present invention relates to deodorization technology at the time of exhaust from a kitchen of a restaurant or from a food or processing plant.

  As part of regional redevelopment in large cities such as Tokyo, Osaka, and Nagoya, the development of high-rise complex facilities is striking. In this type of facility, the lower floors are often commercial districts and the higher floors are residential areas such as offices, hotels and apartments. By the way, in such a complex facility, when kitchen exhaust gas from a restaurant in a commercial area flows into a residential area on the higher floor side, the residential area may flow into the room by taking in outside air using an air conditioner or the like. . As a result, odor complaints are sent to the facility manager. Therefore, a deodorizing process is essential at the time of exhaust in restaurants and the like.

  In the food supermarket, a bento and side dish processing plant is attached at one corner of the store. In the processing plant, processing of grilled meat and fish, fried foods, and the like is performed, and odor is also generated from here. The exhaust is performed so that this kind of odor does not flow into the store on the merchandise display side. By the way, stores in supermarkets are being developed near places of consumption, and houses are often close to the supermarket. Therefore, even in such a supermarket, deodorizing treatment is essential for exhaust.

By the way, the amount of exhaust from the lunch box / prepared food processing plant is about 4000 to 10000 m ³ / hr. The amount of exhaust from the restaurant kitchen of a large complex facility is about 10,000 to 50,000 m ³ / hr in one system. In recent years, the size has increased, and the displacement has increased to about 50,000 to 150,000 m ³ / hr.

  Therefore, the problem to be solved by the present invention is to provide a deodorization technique that can be applied even in the case of a large displacement as described above.

  The present invention is a deodorizing filter. This deodorizing filter has a casing body. The casing body is made of, for example, iron. Alternatively, it is made of a galvanized steel sheet. Alternatively, it is made of ferritic stainless steel. Further, an opening having a vertical dimension of approximately a and a lateral dimension of approximately b is M in the vertical direction (however, M is an integer of 2 or more. Note that M varies depending on the size of the exhaust path and the size of the deodorizing body described later. The general value of is an integer of 3 to 7.) N in the horizontal direction in the row (however, N is an integer of 2 or more. Note that N varies depending on the size of the exhaust path and the size of the deodorizing body described later. The general value of is an integer of 3 to 7.) It has a frame body provided on the outlet side of the casing body, which is formed in a grid by the number of M × N in a row. The frame may be either detachable or non-detachable. Also, the openings having a vertical dimension of approximately a and a lateral dimension of approximately b are M (M is an integer from 3 to 7) in the vertical direction and N (N is an integer from 3 to 7) in the horizontal direction. The M × N number of the frame bodies are detachably provided on the inlet side of the casing body formed in a lattice shape. Here, if at least one of the frames is not detachable, the deodorizing body cannot be replaced inside the casing body. Therefore, the detachable side is merely defined as the entrance side for convenience. Further, the casing body is provided so as to be divided at an interval of approximately dimension c between the outlet-side grid frame and the inlet-side grid frame (L-1) (however, , L is an integer greater than or equal to 2. In addition, although it changes also with the magnitude | sizes of a casing body, the general value of L is an integer of 3-5.) It has an expanded metal body. This expanded metal body not only regulates the position of a deodorizing body, which will be described later, but also functions to rectify the flow of fluid that has passed through the deodorizing body. Then, between the frame body and the expanded metal body and between the expanded metal body and the expanded metal body (provided that L is an integer of 3 or more), M × N are stacked and filled. It has a deodorizing body having a vertical dimension a ′, a horizontal dimension b ′, and a width dimension c ′ (a ′ and b ′ are slightly larger than a and b, and c ′ and c are substantially the same). The weight of the deodorizing filter when the deodorizing body is 100 mm × 100 mm × 60 mm and each of L, M, and N is 3 is about 10 kg, and there is no hindrance to the installation work. Further, as necessary, a preliminary case body having substantially the same dimensions as the frame surface of the casing body is provided. An opening having a vertical dimension of approximately a and a lateral dimension of approximately b is M in the vertical direction (M has the same meaning as described above) and N in the horizontal direction (N has the same meaning as described above). And a frame provided on the outlet side of the preliminary casing body formed in a grid shape by the number of M × N in a row, and an opening having a vertical dimension of approximately a and a lateral dimension of approximately b in the vertical direction. M (M has the same meaning as described above) in a row and N (N has the same meaning as described above) in the horizontal direction. A frame provided on the inlet side of the preliminary casing body, and a vertical dimension a ′, a horizontal dimension b ′, and a width dimension that are stacked by filling M × N pieces between the frame body and the frame body. c ′ (a ′ and b ′ are slightly larger than a and b, and c ′ and c are substantially the same). And it has the magnet provided in the said casing body and / or the said preliminary casing body. As a result, the casing body and the preliminary casing body can be integrated. Note that the detachably provided frame body has a folded portion having an L-shaped cross section, and the folded portion is joined to the casing body by a fastening member.

  The deodorizing apparatus of the present invention is a device in which a plurality of the deodorizing filters are arranged. For example, a plurality are stacked in the vertical direction and the horizontal direction. This deodorizing filter is fixed by, for example, an L-shaped angle. Moreover, the clearance gap between a deodorizing filter and an apparatus casing body is sealed. And a deodorizing filter is arrange | positioned so that it may become a cross-sectional substantially V shape, for example. Or it arrange | positions so that it may become a cross-sectional substantially W shape. That is, if it is arranged in a substantially V-shaped cross section or a substantially W-shaped cross section, it can be reduced in size even in a system with a large displacement.

  This will be described in more detail below.

Deodorization in the kitchen exhaust is performed after the contained oil dust is removed by the grease filter. As the grease filter, for example, a baffle plate system, a ceramic porous body system, an aqua filter system, etc. are known, and the oil dust removal performance is at least about 75%. Deodorization after oil removal is often deodorized by adsorption. For example, a deodorizing filter filled with an adsorbent is installed to adsorb and deodorize odors contained in exhaust gas. As the adsorbent, for example, incombustible zeolite adsorbent or activated carbon is often used from the viewpoint of high contact efficiency and low pressure loss. The present inventor has proposed a honeycomb structure adsorbent containing hydrous magnesium silicate clay mineral as a main component, and has proposed a deodorizing apparatus for kitchen exhaust using the same. For example, a honeycomb shape having dimensions of 10 cm in length, 10 cm in width, and 6 cm in width. The honeycomb-shaped adsorbent is filled and arranged in the case in 3 to 6 rows in the vertical direction and 3 to 6 rows in the horizontal direction, and the deodorizing filter is arranged in the exhaust path. In addition, considering the maintenance such as replacement of the deodorizing filter, the incorporation into this exhaust path is easy to install and remove the deodorizing filter and has a rigid structure that is strong in strength. A concave plate corresponding to the above is attached as a rail, and a deodorizing filter is arranged using this rail. Incidentally, in the case of a displacement of 10,000 m ³ / hr, in order to make the odor concentration 1600 on the inlet side odor concentration 300 or less on the outlet side, the deodorizer is arranged in seven rows in the horizontal direction Using deodorizing filters arranged in five rows in the direction, the deodorizing filters are arranged in two rows in the horizontal direction and three columns in the vertical direction, and further in three stages in the odor flow direction. In the case of a displacement of 40000 m ³ / hr, in order to make the odor concentration 1600 on the inlet side less than 300 on the outlet side, the deodorizer is arranged in five rows in the horizontal direction and in the vertical direction. Six rows of deodorizing filters are used, and these deodorizing filters are arranged in nine rows in the horizontal direction, in three rows in the vertical direction, and in three stages in the odor flow direction. In the case of a displacement of 100000 m ³ / hr, in order to make the odor concentration 1600 on the inlet side less than 300 on the outlet side, the deodorizer is arranged in six rows in the horizontal direction and in the vertical direction. Six rows of deodorizing filters are used, and this deodorizing filter is arranged in 14 rows in the horizontal direction, 4 rows in the vertical direction, and further in 3 rows in the odor flow direction. Thus, as the exhaust air flow increases, the number of deodorizing filters also increases, the area of the surface orthogonal to the flow direction increases, and the length of the deodorizing device does not change, but the vertical and horizontal dimensions Has increased. Therefore, a large space is required.

  Therefore, the present invention has been proposed as a solution to such a problem. In other words, a high-performance deodorizing technique has been proposed that can cope with a system with a large displacement, is low in cost, is easy to install, and is particularly easy to additionally install a deodorizing filter.

FIG. 17 is a plan view of a deodorizing device in which deodorizing filters are arranged in a V-shaped cross section. FIG. 18 is a side view of a deodorizing apparatus in which deodorizing filters are arranged in a V-shaped cross section.

  The block-shaped deodorizing filter of the present invention has a rectangular parallelepiped casing 1 whose front and rear surfaces (left and right surfaces in FIG. 1) are open. The rear surface of the casing 1 (the left surface in FIG. 1) is provided with a grid-like frame body in which three openings are formed in the vertical and horizontal directions, as is apparent from FIG. ing. In addition, the deodorizing body 4 receives position regulation by this frame. That is, the opening is an opening having a vertical dimension a and a horizontal dimension b, the deodorizing body 4 is a deodorizing body having a vertical dimension a ′ and a horizontal dimension b ′, and a ′ and b ′ are lattice-shaped than a and b. Since it is about half the width (for example, about 8 to 10 mm), the deodorizing body 4 stacked by 3 × 3 pieces (9 pieces in total) is regulated at the end by the lattice portion of the frame body and does not fall off. It has become a thing. Further, as can be seen from FIG. 1, the deodorizing bodies 4 are arranged in three stages along the flow direction of the exhaust gas, that is, the width direction. Accordingly, 3 × 3 × 3 (a total of 27) deodorizing bodies 4 are stacked in the casing 1. Between the deodorizing body 4 and the deodorizing body 4 arranged along the width direction, an expanded metal body 3 shown in FIG. 5 is provided. That is, the presence of the expanded metal body 3 provided between the deodorizing body 4 and the deodorizing body 4 makes the deodorizing body 4 difficult to collapse when filling the deodorizing body 4, and improves the workability and deodorizing. The flow of the exhaust gas that has passed through the body 4 is rectified. Thereby, deodorization efficiency comes to be improved. On the front surface of the casing 1 (the right side surface in FIG. 1), as is apparent from FIG. 3, a lattice-like frame body 2 having three openings in the vertical and horizontal directions is provided. . The frame 2 is detachably attached to the casing 1. That is, as can be seen from FIG. 4, a folded portion is formed at the end of the frame body 2 to form a folded portion having an L-shaped cross section, and the surface of the folded portion is joined to the surface of the casing 1 and tightened. It is attached with a member (screw) 5.

  The preliminary deodorizing filter with magnet shown in FIGS. 6 to 9 is connected to the deodorizing filter described in FIGS. 1 to 4 as necessary. That is, when it is desired to increase the deodorizing capacity by providing a deodorizing body only one more stage, the preliminary deodorizing filter with magnet is used. The size and shape of the preliminary deodorizing filter in the vertical and horizontal directions are substantially the same as the size and shape of the deodorizing filter described in FIGS. That is, it has a rectangular parallelepiped casing 6 having open front and rear surfaces (left and right surfaces in FIG. 6). And on the rear surface of the casing 6 (the left surface in FIG. 6), there is provided a grid-like frame body in which three openings are formed in the vertical and horizontal directions. In addition, the deodorizing body 4 receives position regulation by this frame. That is, the opening is an opening having a vertical dimension a and a horizontal dimension b, the deodorizing body 4 is a deodorizing body having a vertical dimension a ′ and a horizontal dimension b ′, and a ′ and b ′ are lattice-shaped than a and b. Since it is about half the width (for example, about 8 to 10 mm), the deodorizing body 4 stacked by 3 × 3 pieces (9 pieces in total) is regulated at the end by the lattice portion of the frame body and does not fall off. It has become a thing. Further, as can be seen from FIG. 6, the front surface of the casing 6 (the right side surface in FIG. 6) has a lattice shape in which three openings are formed in the vertical and horizontal directions, as is clear from FIG. The frame 7 is provided. The frame body 7 is detachably attached to the casing 6. That is, a folded portion is formed at the end of the frame 7 to form a folded portion having an L-shaped cross section, and the surface of the folded portion is joined to the surface of the casing and attached by a fastening member (screw). Furthermore, a magnet is attached to the preliminary deodorizing filter. That is, as can be seen from FIGS. 8 and 9, magnets 8 are fixed by screws 9 at the four corners of the frame 7. Then, by the action of the magnet 8, the preliminary deodorizing filter with magnet of FIGS. 6 to 9 is connected to the deodorizing filter of FIGS. 1 to 4 as shown in FIGS. Therefore, in this case, since the deodorizing body 4 is provided in four stages along the flow direction of the exhaust gas, the deodorizing ability is higher than in the case of only the deodorizing filter of FIGS. Become a thing.

  A deodorizing device is configured using the above-described deodorizing filter (in some cases, a deodorizing filter connected with a preliminary deodorizing filter with a magnet). That is, as can be seen from FIGS. 12 and 13, four deodorizing filters are stacked in the horizontal direction and three in the vertical direction in a cylinder (casing) 10 having a square cross section. That is, a total of 12 deodorizing filters of FIGS. 1 to 4 are used to constitute a deodorizing apparatus. The deodorizing filter has a gap sealed by an L-shaped angle 14. In FIG. 13, the arrow indicates the flow direction of the exhaust gas. In the figure, 11 is a flange for connecting to the duct, 12 is a frame for supporting the casing 10, and 13 is an access door for installing the deodorizing filter.

  Note that the deodorizing filter may be arranged on one side as shown in FIGS. 12 to 16, but may be arranged on a V-shaped cross section (two sides) as shown in FIGS. Or you may arrange | position in the cross-section W shape (four sides). If arranged in such a V or W shape, a large number of deodorizing filters can be arranged in the casing 10 in a single stage, and the deodorization can be efficiently performed even with a large displacement. And a deodorizing apparatus can be comprised compactly.

Next, the case where a hydrous magnesium silicate clay mineral is used as a deodorizing agent (deodorizing body) will be described. The deodorizer comprises 20 to 90 parts by weight of attapulgite, 20 to 90 parts by weight of sepiolite, 20 to 90 parts by weight of aggregate (for example, silica), and 1 to 10 parts by weight of binder (for example, methylcellulose). 100 mm (width) x 100 mm (length) x 60 mm (height: dimension in the odor flow direction) formed by wet kneading, extrusion molding, drying, and firing at a temperature of 500 ° C or less And having a honeycomb structure.
The physical characteristics of the deodorant are shown in Table 1 below.

A deodorizing filter (305 mm × 305 mm × 208 mm) is formed by stacking the deodorizing bodies in a vertical direction, three rows in the vertical direction, three rows in the horizontal direction, and three rows in the width direction (exhaust gas flow direction). Was installed in the exhaust gas flow path of the side dish processing plant (fried food kitchen), and the deodorizing effect was investigated. The results are shown in Table-2.

Pressure loss 103pa 143pa
Odor concentration at the entrance 1600 1600
Outlet odor concentration 200 320
Deodorization efficiency 87.5% 80.0%

  The deodorizing performance was examined by the “three-point comparative odor bag method” based on the malodor control method. That is, the exhaust gas discharged from the sugar beet processing plant is deodorized by the deodorizing device, the gas before the deodorizing device inlet and the gas after the deodorizing device outlet are sampled, and these gases are adjusted to a predetermined concentration. It is diluted and then sniffed by 6 panelists (odor judgment persons) to determine the presence or absence of odor, and the odor concentration is determined when the odor cannot be determined. The odor deodorization performance is calculated by the following formula {Odor deodorization performance (%) = (odor concentration before the entrance portion−odor concentration after the exit portion) / (odor concentration before the entrance portion) × 100}. It was.

Further, since the deodorizing effect was examined in the same manner as described above using a deodorizing apparatus constituted by using a deodorizing filter to which a preliminary deodorizing filter with a magnet of FIGS. 15 and 16 was connected, the result is shown in Table-3. .

Outlet odor concentration 130 160
Deodorization efficiency 91.9% 90.0%

  Comparing Table-3 and Table-2, the degree of deodorization varies depending on the surface wind speed passing through the deodorizer, but in the three-stage deodorization as in Table-2, the surface wind speed is 1.03 m / sec. The deodorization efficiency is 87.5%, the surface wind speed is 1.39 m / sec, and the deodorization efficiency is 80.0%. In the four-stage deodorization as shown in Table 3, the surface wind speed is 1.03 m. / Sec, deodorization efficiency is 91.9%, surface wind speed is 1.39m / sec, deodorization efficiency is 90.0%, and a deodorization filter connected with a pre-deodorization filter with magnets of FIGS.
