Description

Technical Field

[0001] This application relates to a modular component for treating emissions, particularly for treating emissions from equipment used for food cooking, the type of equipment including cooking components such as grills, barbecue grills, or baking pans that emit cooking emissions into the surrounding atmosphere, the cooking emissions specifically including grease, smoke, odors, and water vapor. Background Technology

[0002] The use of devices or equipment that discharge such emissions, whether in homes or public catering establishments, requires the management and removal of pollutants contained in the emissions, in particular to comply with applicable health standards and for the comfort of users and neighbors.

[0003] This includes, in particular, collecting grease and removing fumes and odors, so that at the end of the process of treating the airflow, especially the airflow containing these untreated emissions and pollutants, the treated airflow is "clean" and suitable for direct discharge into the environment, into the outside of the enclosed space where the cooking appliance or equipment is located, or into the interior of the enclosed space itself.

[0004] Currently, most kitchen fume purification devices on the market use activated carbon filtration systems. These systems work by first collecting the fumes through a range hood, then transporting them through pipes to an activated carbon filter box to remove the fumes, and finally exhausting them outdoors via a fan.

[0005] Activated carbon granules are materials with a strong adsorption capacity for various odors. The odor removal capacity of activated carbon granules can reach 82%. However, before odor removal, it is necessary to pre-filter out smoke and oil particles from the air; otherwise, the numerous small pores on the surface of the activated carbon granules will be covered by external grease, immediately rendering the usable adsorption surface of the activated carbon granules ineffective and terminating their odor adsorption function. Therefore, a pre-filter should be installed in the filter box.

[0006] Currently, European countries employ a three-stage filtration system: a synthetic filter, a high-density polypropylene filter, and a high-efficiency synthetic bag filter. While effective initially, this filtration efficiency drops significantly after two to three weeks, requiring replacement after one to two months, especially the first-stage filter, which needs replacement every two to three weeks. Therefore, this smoke filtration structure is no longer accepted in the market because it becomes unusable without frequent filter and activated carbon replacement.

[0007] To date, the most effective way to solve the problem of activated carbon emitting odors is to use a powerful "high-voltage electrostatic" smoke purifier filter before the activated carbon enters the chamber. This is a "dry" electrostatic filter that purifies the smoke without spraying or dispersing any liquid between the electrodes.

[0008] The purified stream then passes through an activated carbon filter, which ensures a longer effective usage time and eliminates concerns about cooking smoke pollution.

[0009] Currently, some specialized companies recommend implementing stand-alone versions of high-voltage electrostatic filters to remove cooking fumes. These products have a fume extraction flow rate of 2200m³ / h. 3 / h (cubic meters per hour), 4400m 3 / h、6600m 3 / h、8800m 3 / h etc.

[0010] However, their boxes are too bulky to be installed in most restaurant locations. Furthermore, they are only 85% to 90% effective at removing cooking fumes or oil fumes, leaving a strong residual odor at the end of the treatment.

[0011] Two filter boxes can be used in series, but they are also quite large; although this arrangement improves the filtration effect, it cannot completely remove grease from the air.

[0012] If a sudden malfunction in the electronic field causes the equipment to temporarily shut down, it can lead to temporary surface contamination of the activated carbon particles. This contamination significantly reduces the activated carbon's ability to adsorb odors, thereby shortening its lifespan.

[0013] To this end, for example, a modular component has been proposed in document FR3068116A1, which includes components arranged in the path of the airflow of the emissions to be treated:

[0014] - An electrostatic fume treatment module, which is adapted to be connected to the source of the emissions to be treated, and in which two electrostatic filters, called "high voltage", are arranged, through which the emissions to be treated flow continuously;

[0015] - and a forced flow system for passing air through these two electrostatic filters.

[0016] The first electrostatic filter has a first processing capacity, and the second electrostatic filter has a second processing capacity.

[0017] The electrostatic filters are adjacent, and thus the airflow to be treated passes sequentially through the first electrostatic filter, the second electrostatic filter, and so on. According to the proposed design, the airflow to be treated continuously undergoes three filtration stages: a mesh filter specifically designed to allow mechanical filtration of grease, two electrostatic filters, and a final set of carbon filters.

[0018] The design proposed in this paper has several drawbacks.

[0019] In particular, using two electrostatic filters arranged in series cannot reliably and adequately ensure continuous operation of the electrostatic filtration function during use and cooking. In fact, if one filter reaches its storage capacity, the storage capacity of the other electrostatic filter alone may not be sufficient to continue operation, as the latter may prove inadequate, and cooking activity must then be stopped.

[0020] This also applies to situations where one and / or the other of the two electrostatic filters fails to supply power.

[0021] Furthermore, the spatial arrangement of individual sub-components or processing modules is cumbersome and difficult to adapt to, especially depending on the location to be equipped and the available space for this purpose.

[0022] This application aims to propose an improved design for modular components that makes it possible to solve all or part of the problems inherent in designs based on the prior art.

[0023] This application specifically aims to provide a processing module that is as efficient as possible in terms of results and daily management, particularly in terms of regular maintenance to maintain its performance. Utility Model Content

[0025] The modular component is characterized by being arranged along the path of the airflow of the emissions to be treated:

[0027] - And, a forced flow module for passing air through the electrostatic filter.

[0028] This fume purifier operates independently. It features at least three stages, employing three high-voltage electrostatic filters, for example, using three independent electrostatic electrode modules within the same housing. This configuration allows for a compact structure, ease of installation, and effective and reliable operation to meet the requirements of downstream activated carbon for smoke and odor removal.

[0041] - The modular component includes a distributor for the airflow of the exhaust gas to be treated on the entire inlet surface of the mechanical pre-filter, which is arranged upstream of the first electrostatic filter through which the airflow of the exhaust gas to be treated passes;

[0042] - The distributor includes at least one distribution baffle that divides the exhaust gas flow into at least two flow segments, each flow segment being directed to an associated portion of the inlet surface of the mechanical pre-filter, distributing the flow segments or flow layers in the horizontal direction of the flow before turning.

[0046] -The filtration capacity of the at least three electrostatic filters is enhanced sequentially along the direction of airflow;

[0047] - The component includes means for indicating the voltage and intensity of each electrostatic filter, and means for selectively controlling each electrostatic filter;

[0070] For the purpose of describing this application and understanding the claims, the vertical, longitudinal, and transverse directions, as indicated by the reference numerals V, L, and T shown in the accompanying drawings, will be used without limitation and with reference to Earth's gravity, wherein the longitudinal axis L and the transverse axis T extend in a horizontal plane.

[0071] In the following description, the same, similar or analogous elements will be represented by the same reference numerals.

[0072] Figure 1 A modular component 100 for treating emissions from devices, particularly cooking devices, is shown. This modular component 100 has an overall tower shape, i.e., its main sub-components or modules are arranged vertically to each other at least partially along axis V.

[0073] Here, from bottom to top—along the flow direction of the emission stream to be treated—modular component 100 includes:

[0074] - Distributor 10 for the airflow of emissions to be treated;

[0075] - Mechanical filtration module 12, also known as a mechanical filter or mechanical pre-filter, is suitable for blocking particles with a size, for example, between 10 micrometers and 100 micrometers;

[0076] -Electrostatic fume treatment module 14, in which three electrostatic filters are arranged, and the emission stream to be treated continuously passes through these three electrostatic filters;

[0077] - Activated carbon filter module 16 or activated carbon filter, which includes 11 activated carbon filter cartridges or filters arranged vertically and in parallel to ensure odor treatment;

[0078] - Forced flow module or system 18 for forcing airflow through modular component 100, particularly through the electrostatic filter of electrostatic smoke treatment module 14.

[0079] Module 18 includes, for example, an exhaust fan 20, by means of which the airflow to be treated that enters through the inlet 22 of the distributor 10 passes through the modular assembly 100 and exits the modular assembly 100 as a purified airflow through the outlet 24.

[0080] Modular component 100 has an overall rectangular parallelepiped shape with an approximately square cross-section.

[0081] Each module has a similar shape.

[0082] In this tower-shaped design, modular components are placed on the ground via a set of legs 26, with the distributor 10 housed between the legs 26.

[0083] like Figure 1 , Figure 2 and Figure 3 As shown, the distributor 10 is in the form of a conduit 30, with its inlet face 22 extending in a vertical and longitudinal plane, and its upper outlet face 28 having a square cross-section extending in a horizontal plane.

[0084] To ensure that the incoming airflow is distributed across the entire surface of the outlet face 28 and thus across the adjacent inlet face 29 of the mechanical pre-filter 12, the duct 30 is divided into three sections by two parallel internal baffles 34.

[0085] The mechanical filter module 12, which is adjacent to the open upper outlet surface 28 of the dispenser 10, has the shape of a box 36. The upper outlet surface 38 of the box 36 is open and includes an open vertical side 40 to allow the placement and removal of the mechanical filter 42 itself. The mechanical filter 42 is in the form of a drawer that slides on the horizontal plane, which makes maintenance operations particularly convenient.

[0086] For treating grease or oily fumes, S-shaped mesh mechanical filters offer excellent filtration efficiency and low head loss, being one to two times more efficient than traditional mesh filters. Their oil and grease filtration efficiency exceeds 60%.

[0087] This filter can block dust and sediment particles ranging in size from 10 micrometers to 100 micrometers. As particles pass through the parabolic concave and convex surfaces of the filter, they are captured, which reduces the charge that subsequently passes through the electrostatic field, resulting in a longer lifespan for the collector plate compared to other similar products.

[0088] The open upper outlet surface 38 is adjacent to the lower inlet surface 50 of the electrostatic fume treatment module 14, and the upper outlet surface 52 of the electrostatic fume treatment module 14 is adjacent to the box of the activated carbon filter module 16.

[0089] In a known manner, the activated carbon filter module 16 includes a plurality of filter cartridges 44 which are detachably arranged in a housing 46, the housing 46 including a plate 47 for bayonet mounting of the filter cartridges 44 and for distributing airflow through the different filter cartridges 44.

[0090] Filtration is performed using a tubular cylindrical metal mesh filter cartridge 44 filled with activated carbon.

[0091] Air filtered by each tubular filter cartridge 44 enters the housing 46 through the cylindrical mesh sidewall, and then exits the housing 46 through the open top 48, through which airflow is drawn in through the forced flow module 18 of the assembly 100.

[0092] The various odor molecules present in the gas flow to be treated are too small in size, typically less than 2.5 micrometers, and they cannot be adsorbed by the electrostatic field when passing through module 14.

[0093] Therefore, it is necessary to filter again with activated carbon to completely adsorb and remove odor molecules in order to obtain purified odorless air.

[0094] The activated carbon has an average lifespan of 10 to 12 months, during which time it does not need to be replaced. The module size and characteristics vary depending on the volume of air to be treated.

[0095] Each filter cartridge 44 contains, for example, 3 kg of activated carbon. The maximum airflow rate that one filter cartridge can handle is 280 m³ / h. 3 / h. Therefore, the required number of filter cartridges should be determined based on the flow rate of the gas to be treated.

[0096] When the activated carbon filter cartridge 44 is placed vertically, it is easier to replace the activated carbon filter cartridge, and the seal at the inlet of each filter cartridge is better.

[0097] If the filter cartridge 44 is installed horizontally (see, for example) Figure 11 and Figure 12The filter cartridge 44 extends cantileveredly from the plate 47, and preferably has a support (not shown) in the form of a retaining bracket 49 arranged in the housing 46 to maintain each filter cartridge 44, especially to ensure a good seal at the joint at the inlet or opening of each filter cartridge (see See Figure 18 ).

[0098] This support or bracket 49 is arranged and secured by screws 51 to support the filter cartridge at its free cantilever end, ensuring good condition of the joint by preventing deformation due to gravity and vibration. The lack of this support will lead to air leakage and poor odor filtration.

[0099] As a variation, and especially if the available height is insufficient to install the activated carbon filter module 16, the activated carbon filter module 16 can be placed downstream of the outlet of the forced airflow module 18 to ensure better acoustic results at the outlet.

[0100] In particular, refer to Figures 4 to 6 The design of the electrostatic fume treatment module 14 will be described here. The electrostatic fume treatment module 14 is equipped with three electrostatic filters, through which the emission stream to be treated passes continuously.

[0101] Regardless of whether module 14 is arranged vertically or horizontally, its overall design remains the same. Figure 5 ).

[0102] The electrostatic smoke treatment module 14 has an elongated structure in the shape of a rectangular parallelepiped, including two opposing functional end faces. The first end face 50 forms the inlet face of the airflow to be treated through the module 14, and the second end face forms the outlet face 52 of the airflow to be treated.

[0103] When module 14 is arranged vertically, the parallel inlet surface 50 and outlet surface 52 are horizontal; while when module 14 is arranged horizontally, the parallel inlet surface 50 and outlet surface 52 are vertical.

[0104] Here, the electrostatic smoke treatment module 14 includes three electrostatic filters arranged in sequence, through which the airflow to be treated flows in series.

[0105] As a variant, the module may include four consecutively arranged electrostatic filters for higher efficiency, if desired.

[0106] Each module 14 has the shape of a box 56, which includes an open side 58 that provides an inlet to three accommodating parts 59P, 59S, and 59T. Each accommodating part 59P, 59S, and 59T respectively accommodates one of three electrostatic filters or high-voltage electrostatic field filters. The three electrostatic filters, along the passage direction of the module 14, sequentially include a primary filter 60P, a secondary filter 60S, and a tertiary filter 60T.

[0107] Here, the open side 58 is closed by two adjacent hinged doors 62A and 62B, each hinged door including a device 63 that allows electrical connection and power supply for different filters 60P, 60S and 60T.

[0108] The exterior of each door 62A, 62B is itself closed by an associated hinged cover 64A, 64B, which allows access to the components and elements 65 required to power each filter 60P, 60S, 60T arranged in the internal volume of doors 62A and 62B.

[0109] Each filter and associated electrostatic field is powered by an independent power source.

[0110] Therefore, the operation of each electrostatic filter (60P, 60S, 60T) will not affect the operation of another filter. If one filter malfunctions, it will not affect the operation of the other filters, which can continue to operate.

[0111] In this way, a sufficient and satisfactory smoke filtration ratio can be obtained without causing short-term contamination to the activated carbon used in the filter module 14.

[0112] Although it is a three-stage filter box, the volume of box 56 is particularly small, and the overall size of box 56 is shorter than that of a similar two-stage filter box.

[0113] The main length of the box is approximately 110 cm. This box is suitable for installation in small, specialized locations, such as restaurants.

[0114] Reference Figure 6 The schematic diagram shows that downstream of the mechanical pre-filter 12, each filter 60P, 60S, 60T includes a needle-shaped positive electrode 61 (15kV), a plate-shaped negative electrode 66 (0V), a photoelectron high-voltage field 68, a positive electrode plate 72 (7kV), a negative electrode plate 70 (0V), and a medium-voltage electrostatic field 74.

[0115] After such a smoke extraction cycle, the optimal smoke extraction rate, which is between 90% and 95% according to existing technology, is exceeded.

[0116] For example, if the smoke particles in the air are 100g / m³ 3(grams per cubic meter), the remaining smoke particles after the air passes through the first 60P filter are 5 g / m³. 3 After 60 seconds of filtering with the second filter, the remaining smoke particles were 0.25 g / m³. 3 Furthermore, the smoke extraction rate is 99.75%.

[0117] Thanks to the third 60T filter, only 0.0125g / m³ remained. 3 This achieves a total smoke emission rate of 99.9875%.

[0118] The electrode plates are coated with, for example, a layer of copper or gold nanoparticles. Oil fumes or grease particles automatically detach, extending the lifespan by approximately two to three months, more than three times that of ordinary aluminum electrode plates.

[0119] Alternatively, a coating technique using conductive epoxy resin can be used.

[0120] Traditional electrode plates are made of aluminum alloy plates known as aerospace-grade aluminum. Under the influence of high-voltage electrostatic fields of 16 kV and 8.6 kV, the surface oxidizes. The optimal lifespan of ordinary electrode plates is only six to nine months. Once this period is exceeded, the purification rate decreases. Therefore, chemical cleaning is necessary. After multiple cleanings, replacement is required every three years.

[0121] Thanks to the electrode plates manufactured using a new conductive epoxy resin coating technology, grease will not adhere to the waterproof surface. Oil droplets or grease fall off automatically without sticking, and the plates maintain optimal conductivity and corrosion resistance for a long time. This saves on consumables and significantly reduces the frequency of cleaning, simplifying maintenance and upkeep. The electrostatic filter has a service life of three to five years.

[0122] Depending on the on-site installation requirements, the electrostatic smoke filter module 14 can be of various types, such as having a left air inlet, a right air inlet, or a lower air inlet in a vertical position.

[0123] An airflow equalization plate may need to be installed at the airflow inlet, and the location of the equalization plate varies depending on the type of module selected.

[0124] In addition, a control box and an indicator light can be installed on the front of the box. The indicator light shows that one and / or another of the three electrostatic filters is saturated, so that users can detect this status and clean the relevant electrostatic filters before the next use on the market.

[0125] The control block may also include indicator lights to show whether the components are powered on, buttons to activate the electrostatic field of filters 60P, 60S, and 60T, buttons to control the operation of the exhaust fan, and a speed control for the exhaust fan.

[0126] More specifically, the modular arrangement includes an indicator for indicating the charge state of each electrostatic filter and a control device for selectively controlling each electrostatic filter.

[0127] Depending on the nature and composition of the exhaust gases to be treated and purified, their moisture content may be very high—for example, in the case of cooking steam—and the moisture they contain may impair the proper and efficient operation of the electrostatic treatment module 14.

[0128] To overcome this problem, it is recommended that a device for at least partially removing water vapor and / or water droplets contained in the exhaust gas stream be associated with the modular arrangement 100—upstream of the electrostatic treatment module 14.

[0129] This device can be placed anywhere along the path of the exhaust gas before it reaches module 14, and for example, upstream of inlet 22 in distributor 10.

[0130] The device can be a dynamic centrifugal separator and / or a dynamic condenser separator.

[0131] Figure 7 and 8 A design example of a dynamic centrifugal separator 80 is shown.

[0132] exist Figure 7 In the diagram, separator 80 is shown in its operating position, with the lower recovery housing 82 of separator 80 in a horizontal position and the conduit 84 of the lower recovery housing 82 for discharging the recovered liquid condensate in a vertical direction and opening downward.

[0133] The lower housing 82 includes a central hole 83 for allowing airflow.

[0134] The centrifugal phenomenon that causes dynamic condensation is obtained by a centrifugal wheel or centrifugal propeller 86, which rotates at high speed under the drive of a motor 88.

[0135] The propeller 86 rotates inside the upper cylindrical casing 88, which opens upward to allow airflow.

[0136] The propeller 86 centrifuges the airflow inside the outer casing 88, and the condensate formed along the inner cylindrical surface 90 of the outer casing 88 falls into the lower casing 82.

[0137] Figure 19 These are perspective and transparent views of two dynamic centrifugal separators 80 arranged in parallel within module or box 81.

[0138] Figure 9A first example is shown of a modular treatment component 100 in the shape of a vertical tower installed in a purification device for the emissions of a cooking appliance.

[0139] Modular component 100 is shown in this figure in a simplified schematic manner.

[0140] The airflow to be processed is collected by a range hood 102 arranged in the space, for example above a cooking appliance, and a first duct 104 connects the range hood 102 to an inlet at the lower part of the modular assembly 100.

[0141] The second conduit 105 connects the outlet of the forced flow module 18 to the site's isolation outlet 106.

[0142] Figure 10 It shows Figure 9 A variation of the example in which the activated carbon filter module 16 is not part of the tower-shaped modular arrangement 100, but is instead placed downstream of the outlet of the forced flow module 18 that allows airflow through the assembly 100.

[0143] Figure 11 A first embodiment of a modular processing assembly 100 is shown, which is horizontally arranged in a purification device for emissions from a cooking appliance.

[0144] According to a variant not shown, arrangement 100 can be horizontally positioned directly above range hood 102.

[0145] Figure 12 It shows Figure 10 The variant installed in the middle, in one aspect, allows airflow to pass through the forced flow module 18 of component 100 and the activated carbon filter module 16 in this order, and is separate from other modules of the modular arrangement 100.

[0146] Figure 13 It shows Figure 10 Another variation of the “horizontal” installation, in which the modular arrangement 100 is horizontally arranged below the cooking device 106.

[0147] Figures 14 to 16 The upper front portion of motor vehicle 200 is partially shown, which is internal to (see...) Figure 15 )A cooking device 202 is equipped with a discharge device for processing wastewater.

[0148] For example, the vehicle is a food preparation and delivery vehicle equipped with a cooking device 202.

[0149] The vehicle 200 includes a front or cab 204, which is defined forward by a windshield 206 and upward by a portion of a roof or top 208.

[0150] The modular component 100 of the above type is arranged horizontally along the lateral side of the vehicle 200 above the roof 208 of the front cab 204.

[0151] This installation is made possible by the extremely compact nature of the modular component 100.

[0152] Therefore, the vehicle 200 equipped in this way can be installed in any permitted location and operate without producing any unauthorized emissions or odors.

[0153] Figure 17 Another example of the implementation and installation of a modular component 100 for treating emissions is shown, which allows for the realization of a stand-alone and portable cooking station 300 with extremely high filtration capacity for odors and fumes.

[0154] Modular component 100 is arranged horizontally at the lower part of independent and movable cooking station 300, below horizontal work plane 302.

[0155] At the top and above the working plane 302, the mobile station 300 includes a range hood 102, the outlet of which is connected via a vertical and horizontal duct 102 to the inlet of a modular component 100 for treating emissions.

[0156] In the lower part, the conduit 102 can be integrated with the dispenser as described above.
