Description

Technical Field

[0001] This utility model belongs to the technical field of waste gas treatment equipment, and specifically relates to a particulate matter separator. Background Technology

[0002] Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory area. During the treatment of industrial waste gas tail gas, due to excessive dust and smoke, the emitted air will pollute the environment. In the process of treating these waste gases, it is usually necessary to first filter out the solid dust particles contained therein.

[0003] To capture and separate solid particles from exhaust gas, a particulate separator is usually required. Currently, particulate separators typically use packing blocks to perform preliminary filtration of particles in the exhaust gas. The packing blocks are usually placed horizontally in the airflow channel to preliminarily filter larger solid particles in the gas passing through the packing blocks.

[0004] However, the contact area of ​​the packing material is small due to its horizontal placement, resulting in poor filtration. To improve the poor effect of preliminary filtration using packing material, multi-layer packing material is currently used for preliminary filtration. However, the filtration channel formed by stacking multiple layers of packing material can lead to poor gas flow, affecting the overall treatment efficiency.

[0005] Therefore, when separating solid particles from waste gas, it is urgent to solve the problem of how to achieve good separation effect of solid particles and ensure good gas flow. Utility Model Content

[0006] To address the shortcomings of existing technologies, a particulate separator is provided to solve the problems of poor separation effect and low efficiency.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A particulate matter separator, comprising:

[0008] The furnace body has at least one partition inside, with one end of the partition suspended in the air. The partition is used to divide the interior of the furnace body into several interconnected cavities. The several cavities are connected in sequence to form a gas flow channel. The furnace body is provided with an air inlet and an air outlet corresponding to the beginning and end of the gas flow channel, respectively.

[0009] A first filter device is disposed in the furnace body, near the air inlet. The first filter device includes several inclined filter blocks, which abut each other end to end to block the gas flow channel.

[0010] A heat exchange device is located downstream of the first filter device and is used to cool the exhaust gas.

[0011] The second filtration device is located downstream of the heat exchange device.

[0012] Compared with existing technologies, the above technical solutions have the following beneficial effects:

[0013] A baffle is installed in the furnace body to divide the interior into gas flow channels. A first filter device, a heat exchange device, and a second filter device are sequentially installed in the flow channels to perform preliminary filtration, heat exchange, and a second fine filtration. In the first filter device, the filter blocks are inclined and their ends abut each other, which ensures that more filter blocks can be placed in the flow channel of the same size, and that the passing gas can come into contact with more filter blocks. The filter blocks are connected end to end to ensure the flow of gas.

[0014] Based on the above technical solution, the embodiments of this application can be further improved as follows:

[0015] In one embodiment, the first filtering device further includes a plurality of support grooves for clamping the filter block. The support groove includes an upper groove and a lower groove, the upper groove and the lower groove are disposed on different vertical planes, the upper grooves in adjacent support grooves abut against each other, and the lower grooves in adjacent support grooves abut against each other.

[0016] The filter block is fixedly clamped by the mounting slot. The upper and lower slots of the mounting slot are staggered on different vertical surfaces, so that the filter block inserted into the mounting slot is in an inclined state, and the upper and lower slots abut against each other without leaving gaps, so that the airflow can only pass through the filter block.

[0017] In one embodiment, the furnace body is provided with an oil drain port that communicates with its interior, and the inner wall of the oil drain port is flush with the inner bottom of the furnace body.

[0018] In one embodiment, the heat exchange device includes:

[0022] In one embodiment, the finned tube assembly includes a plurality of finned tubes arranged sequentially from top to bottom. The two ends of the finned tubes are fixedly installed in the housing. The finned tubes arranged from top to bottom are staggered left and right, and the two ends are connected sequentially by elbows.

[0023] By arranging the finned tubes alternately on the left and right and connecting them end to end with elbows, a zigzag-shaped arrangement can be formed. Within the same length range, more finned tubes can be arranged, thus improving heat exchange efficiency.

[0024] In one embodiment, the second filtration device includes:

[0025] A support plate having a plurality of mounting holes;

[0026] Several filter elements are matched and disposed in the mounting holes.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0048] like Figure 1-4 As shown, the particulate separator provided by this utility model includes: furnace body 1, first filter device 5, heat exchange device 6, and second filter device 7.

[0049] The furnace body 1 has at least one partition 2 inside. One end of the partition 2 is suspended, and the end of the partition 2 is not connected to the inner wall of the furnace body 1, which facilitates the passage of airflow. The partition 2 is used to divide the interior of the furnace body 1 into several interconnected cavities. The several cavities are connected in sequence to form a gas flow channel. Specifically, the bottom and top of multiple partitions 2 are alternately suspended, thus forming a continuous gas flow channel. The gas flow channel forms a continuous S-shape, making full use of the internal space of the furnace body 1. In this embodiment, there is one partition 2. The top and sides of the partition 2 are connected to the inner wall of the furnace body 1, and the bottom is suspended, dividing the interior of the furnace body 1 into a first cavity on the right and a second cavity on the left. The furnace body 1 is provided with an air inlet 3 and an air outlet 4 corresponding to the beginning and end of the gas flow channel. The air outlet 4 and the air inlet 3 are located on the top of the left and right sides of the furnace body 1, respectively, and correspond to the first cavity and the second cavity. The air inlet 3 is also connected to the furnace body 1 through a conical top.

[0050] The first filter device 5 is disposed in the furnace body 1, near the air inlet 3. The first filter device 5 includes several inclined filter blocks 501, wherein the filter blocks 501 can be filter blocks 501 formed by regular packing. The filter blocks 501 are connected end to end to seal the gas flow channel. The edges of the filter blocks 501 are attached to the inner wall of the furnace body 1. Two inclined filter blocks 501 are connected end to end to form a V-shaped structure. After multiple filter blocks 501 are connected in sequence, the entire gas flow channel is sealed. Compared with a single single-layer filter block 501, the contact area with the gas is increased. The inclined filter blocks 501 effectively utilize the entire area on the filter block 501.

[0051] The heat exchange device 6 is located downstream of the first filter device 5, below the first filter device 5 in the first cavity, and is used to cool the exhaust gas. It cools the gas after the large particles have been initially filtered out, making full use of the high-temperature flue gas. Then, it is filtered again by the second filter device 7 to remove even smaller dust particles. The second filter device 7 is located downstream of the heat exchange device 6, specifically in the second cavity of the furnace body 1.

[0052] A baffle 2 is installed in the furnace body 1 to divide the interior of the furnace body 1 into gas flow channels. A first filter device 5, a heat exchange device 6, and a second filter device 7 are sequentially installed in the flow channels to perform preliminary filtration, heat exchange, and a second fine filtration. In the first filter device 5, the filter blocks 501 are inclined and their ends abut each other, which ensures that more filter blocks 501 can be placed in the flow channel of the same size, and that the passing gas can come into contact with more filter blocks 501. The filter blocks 501 are connected end to end to ensure the flow of gas.

[0053] To facilitate the installation of the filter block 501, the first filter device 5 further includes several support grooves 502 for clamping the filter block 501. The support grooves 502 are fixedly installed in the furnace body 1. When replacement is needed, the filter block 501 can be pulled out, which facilitates the positioning of the filter block 501 and the installation. The support groove 502 includes an upper groove opening 5021 and a lower groove opening 5022. The upper groove opening 5021 and the lower groove opening 5022 are set on different vertical surfaces and are arranged opposite to each other. In this way, the filter block 501 can be inserted at an angle between the upper groove opening 5021 and the lower groove opening 5022.

[0054] The upper slots 5021 in adjacent support slots 502 are connected to each other, and the lower slots 5022 in adjacent support slots 502 are connected to each other. The upper slot 5021 or lower slot 5022 of the outermost support slot 502 is connected to the inside of the furnace body 1, encompassing the gas flow channel inside the entire furnace body 1. The upper and lower slots 5022 abut against each other without gaps, so that the airflow can only pass through the filter block 501, ensuring that the gas passing through the filter block 501 in the installation slot is filtered.

[0055] To remove the sediment produced by filtration, the furnace body 1 is provided with an oil drain port 8 that connects to its interior. The inner wall of the oil drain port 8 is flush with the inner bottom of the furnace body 1, which facilitates the discharge of sediment that falls into the furnace body 1 through the oil drain port 8. The flush setting of the oil drain port 8 ensures that there are no dead corners at this position.

[0056] In this embodiment, as Figure 2 , 3 As shown, the heat exchange device 6 includes: a shell 501, several finned tube assemblies 602 and two manifolds 603.

[0057] The shell 501 consists of a tube sheet and side plates fixed to the outer periphery of the finned tube assembly 602. The heat exchange device 6 is fixed in the furnace body 1 through the shell 501. Multiple reinforcing plates are arranged around the outer ring of the shell 501. The reinforcing plates are connected and fixed to the inner wall of the furnace body 1 to enhance the tightness between the heat exchange device 6 and the furnace body 1. Several finned tube assemblies 602 are arranged side by side and fixedly installed in the shell 501. The two manifolds 603 are respectively connected to the two ends of several finned tube assemblies 602, serving to connect the inlet and outlet of multiple finned tube assemblies 602. The manifolds 603 are connected to the internal pipes 604. The pipes 604 extend to the outside of the furnace body 1 and are used to connect to and discharge water after heat exchange.

[0058] Specifically, the finned tube assembly 602 includes a plurality of finned tubes 6021 arranged sequentially from top to bottom. Both ends of each finned tube 6021 are fixedly installed in the housing 501. The finned tubes 6021 are staggered left and right from top to bottom, and their ends are connected sequentially by elbows 6022. The elbows 6022 connect to the ends of adjacent upper and lower finned tubes 6021, connecting the two finned tubes 6021 together to ensure communication. Due to the staggered arrangement of the finned tubes 6021, after being connected end-to-end by the elbows 6022, a zigzag-like arrangement is formed, such as... Figure 2 As shown, within the same length range, more finned tubes 6021 can be arranged, improving heat exchange efficiency.

[0059] In this embodiment, as Figure 1 As shown, the second filtration device 7 includes a support plate 701 and a plurality of filter elements 702.

[0060] The support plate 701 is fixed inside the furnace body 1. The support plate 701 is horizontally placed in the second cavity to block the entire gas flow channel. The support plate 701 has several mounting holes. The filter element 702 is matched and installed in the mounting holes, so that the gas passing through needs to be filtered by the filter element 702 before it can enter the gas outlet 4 for discharge.

[0061] To ensure the effective positioning and installation of the filter element 702, the top of the filter element 702 is provided with an end edge 703 that abuts against the surface of the support plate 701. The end edge 703 is fixed to the top edge of the filter element 702, and the outer diameter of the end edge 703 is larger than the diameter of the mounting hole, so that the end edge 703 abuts against the support plate 701, and the top of the filter element 702 hangs on the support plate 701. In addition, the bottom of the filter element 702 is provided with a support member 704, which provides support from the bottom.

[0062] The filter element 702 is provided with a frame that is fixed to the support member 704 and the end edge 703, which facilitates the force on the support member 704 and the end edge 703 and plays a supporting role.

[0063] Furthermore, the top of the furnace body 1 corresponding to the second cavity is set as an open opening, and a cover plate is set for the open opening. After removing the cover plate, it is convenient to take out and replace the entire filter element 702 from the top.

[0064] To facilitate maintenance of the furnace body 1 and replacement of consumables at each stage, an inspection port 9 is provided on the furnace body 1 corresponding to the gas flow channel, and an inspection door 10 is connected to the inspection port 9. Figure 4 As shown, the inspection door 10 has its edge folded over and abuts against the outer wall of the furnace body 1. The folded edge of the inspection door 10 can improve the sealing effect of the inspection door 10. After the inspection door 10 is closed, the edge of the inspection door 10 abuts against the surface of the furnace body 1. Fasteners 11 are threaded around the inspection door 10 and are screwed to the furnace body 1. The fasteners 11 can be bolts or the like. By opening screw holes or setting nuts on the furnace body 1, the inspection door 10 can be fixed to the inspection port 9 of the furnace body 1 by bolts. Specifically, the inspection port 9 can be opened in one of the cavities corresponding to the first filter device 5, located in the first cavity at the upper and lower ends of the heat exchange device 6, which is convenient for maintenance of the second cavity of the second filter device 7.

[0065] like Figure 4 As shown, in order to ensure the sealing effect of the inspection door 10 and the inspection port 9, the edge of the inspection port 9 is provided with a short edge 12 extending toward the inspection door 10, and the inner wall of the inspection door 10 is provided with a sealing groove 13 that matches the short edge 12.

[0066] After the inspection door 10 is closed and fixed on the inspection port 9, the sealing groove 13 on the inspection door 10 matches the shorting edge 12 at the inspection port 9. The sealing groove 13 seals the shorting edge 12 accordingly. The sealing groove 13 can be filled with asbestos rope, etc., which further improves the sealing effect of the inspection door 10.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
