Description

Technical Field

[0001] The invention relates to the technical field of flue gas purification, and in particular to a flue gas transfer device for a glass fiber preparation electric furnace. Background Art

[0002] Glass fiber is an inorganic non-metallic material with excellent performance, and has the advantages of light weight, high strength, and corrosion resistance. During the melting stage of the glass fiber preparation process, the glass fiber raw materials need to be placed in an electric furnace for high-temperature melting. However, the electric furnace will produce a large amount of flue gas, which mainly includes particulate matter, volatile substances and other harmful gases. In order to protect the environment and the health and safety of workers, it is necessary to carry out corresponding harmless treatment before discharge.

[0003] However, there are usually some problems when harmlessly treating flue gas. With the development of science and technology, technicians in related fields have also made a lot of optimizations on the treatment of flue gas. In order to make a more accurate comparison, a Chinese patent with publication number CN215352753U discloses a semi-enclosed electric furnace flue gas high-efficiency purification system, including a pipeline mechanism and a filtering mechanism. The pipeline mechanism includes a purification tower, an induced draft fan and a dust collecting assembly. The induced draft fan is connected to one side of the purification tower, and the inclined plate and the baffle are respectively installed on both sides of the inner wall of the purification tower. The dust collecting assembly includes an ash hopper connected to the inner wall of the purification tower, and a backflow prevention plate is installed on the inner wall of the ash hopper; a flue gas outlet is opened at the top of the purification tower, and the filtering mechanism includes a dust removal assembly installed on the inner wall of the purification tower. Two hanging racks are set and connected to the inner wall of the dust removal assembly, and the filter bag is installed on the inner side of the hanging rack.

[0004] When the above-mentioned prior art is in use, the induced draft fan transports the flue gas into the purification tower, and the inclined plate and the baffle are used to divert the flue gas to flow into the ash hopper, so that the coarse dust particles in the gas flow directly into the ash hopper and enter the pre-dust collection; then the filter bag filters the dust in the flue gas, and the clean air is discharged into the atmosphere through the flue gas outlet pipe and the flue gas outlet, and then the filter bag is controlled to expand to make the dust accumulated on its surface fall off, and then the dust is collected; during this period, it can be detected whether the dust collected in the ash storage tank has reached the set capacity, which is convenient for handling dust.

[0005] However, there are still some shortcomings in the process of treating flue gas in the above-mentioned prior art:

[0006] 1. Since the flue gas contains not only particulate dust but also volatile substances and harmful gases, the above-mentioned prior art can only remove particulate dust in the flue gas through the filter bag, but cannot filter out volatile substances and harmful gases, resulting in the treated flue gas still polluting the environment, thereby affecting the treatment effect of the flue gas.

[0007] 2. Because the particulate dust in the flue gas is in a dry state when it is discharged into the purification tower, the dust in the flue gas cannot settle down quickly and is easy to fly. When it is necessary to replace the filter bag or deal with the dust in the ash storage tank, the dust in the purification tower is easy to fly out, which not only pollutes the environment, but also affects the health and safety of the staff.

[0008] Therefore, based on the above-stated viewpoint, there is still room for improvement in existing flue gas treatment methods. Summary of the invention

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-Figure 8 Embodiments of the present invention are described in detail.

[0039] The embodiment of the present application discloses a glass fiber preparation electric furnace flue gas transfer device. It should be noted that the glass fiber preparation electric furnace flue gas transfer device of the present application is mainly used in the process of filtering vegetable oil. In terms of technical effect, it can sequentially perform preliminary spraying of the flue gas through the spray unit 2, complete dust removal and filtration of the flue gas through the dust removal unit 3, and perform biocatalysis and adsorption purification of the flue gas through the purification unit 4, thereby effectively removing dust, particulate matter, volatile substances and other harmful gases in the flue gas; especially during the dust removal and purification of the flue gas, the flue gas can be pressed down so that the flue gas quickly enters the liquid collection cylinder 13 downward, so that the liquid medicine in the liquid collection cylinder 13 performs secondary biocatalysis on the flue gas, and prevents the liquid medicine in the liquid collection cylinder 13 from blocking the flue gas, making it difficult for the flue gas to pass through the liquid collection cylinder 13 and affecting the purification effect; further, the glass fiber preparation electric furnace flue gas transfer device can also remove volatile substances and harmful gases in the flue gas by adsorption filtration and liquid medicine immersion, thereby achieving comprehensive purification of the flue gas.

[0040] Embodiment 1:

[0041] Reference Figure 1 and Figure 2As shown, a glass fiber preparation electric furnace flue gas transfer equipment includes a transfer cylinder 1, which is a U-shaped structure. The two vertical sections of the transfer cylinder 1 are an air intake cylinder 11 and an exhaust cylinder 12 for pre-treating the flue gas and discharging the treated flue gas, respectively. A liquid collection cylinder 13 that is interconnected is installed between the air intake cylinder 11 and the exhaust cylinder 12. The liquid collection cylinder 13 contains chemical liquid for biocatalysis of the flue gas. The inner wall of the air intake cylinder 11 is sequentially provided with a spray unit 2 and a dust removal unit 3 from top to bottom.

[0042] Furthermore, in this embodiment, the spray unit 2 includes a spray head 21 installed on the side wall of the air inlet cylinder 11, the dust removal unit 3 includes an opening and closing door 31 rotatably arranged on the side wall of the air inlet cylinder 11, and a filter plate 32 is installed on the inner wall of the opening and closing door 31, and the filter plate 32 is against the inner wall of the air inlet cylinder 11; the inner wall of the liquid collection cylinder 13 is installed with a purification unit 4 for adsorbing and filtering the flue gas after dust removal, and the purification unit 4 includes an activated carbon filter element 41 arranged inside the liquid collection cylinder 13.

[0043] In the specific implementation process, the smoke outlet of the electric furnace is first connected to the air inlet 11, and then the smoke in the electric furnace enters the air inlet 11. During this period, the smoke in the air inlet 11 is preliminarily sprayed and dust-filtered in turn by the spray unit 2 and the dust removal unit 3 to remove particulate matter in the smoke; then the filtered smoke enters the liquid collection tube 13 for biocatalytic treatment, so that the purification unit 4 adsorbs and purifies the smoke, and during this period, the reactants of the smoke after biocatalysis can also be filtered, so as to achieve comprehensive purification of the smoke, and the purified smoke is discharged through the exhaust pipe 12.

[0044] Continue to refer to Figure 2 As shown, in order to prevent the smoke from drying out and causing the dust therein to fly, and the rapid precipitation of particulate matter in the smoke, based on this, in this embodiment, the smoke can be subjected to corresponding spray treatment. Specifically, the spray unit 2 also includes an annular cylinder 22 mounted on the outer wall of the air inlet cylinder 11, and annular frames 23 are fixedly installed at the upper and lower ends of the annular cylinder 22. The annular frame 23 is fixedly mounted on the outer wall of the air inlet cylinder 11, and a plurality of annularly distributed and connected spray heads 21 are evenly installed on the inner wall of the annular cylinder 22, and the output end of the spray head 21 passes through the air inlet cylinder 11 and extends to the interior thereof; a water pump 24 is installed on the upper end of the liquid accumulation cylinder 13 through a bracket, and the input end of the water pump 24 extends to the interior of the liquid accumulation cylinder 13, and the output end of the water pump 24 is connected to the annular cylinder 22 through a connecting pipe.

[0045] During the specific implementation process, when the flue gas enters the air inlet cylinder 11, the water pump 24 is started, and the water pump 24 discharges the liquid medicine in the liquid collection cylinder 13 into the annular cylinder 22. Then the spray head 21 sprays the liquid medicine in the annular cylinder 22, so that the liquid medicine sprays the flue gas, and the spraying effect can be enhanced by spraying the flue gas at the same time by multiple spray heads 21. The spraying method adopted in this way can not only reduce the dust generated by the flue gas during the purification process, but also make the particles in the flue gas adhere to the liquid medicine on the surface and then quickly settle downward, thereby accelerating the purification efficiency, and can also preliminarily catalyze the harmful substances in the flue gas through the liquid medicine, so as to enhance the purification effect of the flue gas.

[0046] Reference Figure 3 As shown, since the flue gas contains a large amount of dust and particulate matter, in order to improve the purification efficiency and effect of the flue gas, it is necessary to carry out corresponding dust removal treatment on the flue gas after spraying. Based on this, a dust removal unit 3 is provided in this embodiment. Specifically, the filter plate 32 is detachably mounted on the inner wall of the opening and closing door 31. The dust and particulate matter in the flue gas can be filtered out by the filter plate 32, and the filter plate 32 can be easily removed and the dust and particulate matter on its upper end can be poured out, so that the filter plate 32 can be reused; the dust removal unit 3 also includes a support bar 33, and the inner wall of the opening and closing door 31 is provided with two support bars 33 located above the filter plate 32, and the end of the support bar 33 away from the closing door 31 is installed with a folded edge connected to the top of the filter plate 32, and the opening and closing door 31 is also provided with a pressurizing component 34 for accelerating the flue gas to pass through the filter plate 32.

[0047] During the specific implementation process, the support bar 33 can provide support force for the filter plate 32, so that the filter plate 32 always remains in a horizontal state and will not fall under the action of gravity. In addition, when the opening and closing door 31 is closed, the filter plate 32 can be driven to lean against the inner wall of the air inlet cylinder 11, thereby preventing smoke from passing through the gap between the filter plate 32 and the air inlet cylinder 11 and affecting the purification effect.

[0048] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, since the liquid storage cylinder 13 is filled with liquid medicine, the smoke in the air intake cylinder 11 cannot pass through the liquid medicine when passing through the liquid storage cylinder 13. Based on this, a pressurizing component 34 for allowing the smoke to pass through the liquid medicine is provided in this embodiment. Specifically, the pressurizing component 34 includes a horizontal plate 341. Two horizontal plates 341 are installed on the inner wall of the opening and closing door 31, and are located above the filter plate 32 and distributed up and down. A bidirectional screw 342 that coincides with the axis of the air intake cylinder 11 is rotatably arranged between the two horizontal plates 341. A driving motor 343 connected to the bidirectional screw 342 is installed on the upper end of the upper horizontal plate 341 through a motor seat.

[0049] Furthermore, in this embodiment, a reciprocating plate 344 is sleeved on the outer wall of the bidirectional screw 342 by means of a threaded connection, and a support rod 345 that slides through the reciprocating plate 344 is installed between the two horizontal plates 341. The support rod 345 can limit the rotation direction of the reciprocating plate 344 to prevent the reciprocating plate 344 from rotating, so that when the bidirectional screw 342 rotates, it can only drive the reciprocating plate 344 to move up and down, and the outer wall of the reciprocating plate 344 slides with the inner wall of the opening and closing door 31 and the air intake cylinder 11. A plurality of through holes 346 are opened on the reciprocating plate 344, and a sealing plate 347 is provided on the inner wall of the through hole 346.

[0050] It should be noted that the outer wall of the bidirectional screw 342 provided in this embodiment is provided with two sets of symmetrically arranged and interconnected transmission threads, the bidirectional screw 342 is used to drive the reciprocating plate 344 to move back and forth up and down, and the inner wall of the reciprocating plate 344 is symmetrically installed with two support pins that slide against the inner wall of the transmission thread.

[0051] Furthermore, in this embodiment, the pressurizing assembly 34 also includes a filter cover 348 , and a plurality of filter covers 348 disposed outside the through hole 346 are detachably mounted on the lower end of the reciprocating plate 344 , and a mounting frame 349 is disposed between the plurality of filter covers 348 .

[0052] In the specific implementation process, after the flue gas enters the air intake cylinder 11 and is sprayed, the drive motor 343 is started, and the drive motor 343 drives the bidirectional screw 342 to rotate, and the bidirectional screw 342 drives the reciprocating plate 344 to move back and forth up and down. When the reciprocating plate 344 moves up, the flue gas in the air intake cylinder 11 passes through the through hole 346 and the sealing plate 347 and then enters the bottom of the reciprocating plate 344. At this time, the smoke after spraying can be preliminarily filtered through the filter cover 348.

[0053] Then the reciprocating plate 344 moves downward, during which time the sealing plate 347 closes the through hole 346, so that the reciprocating plate 344 cooperates with a plurality of sealing plates 347 to press down the flue gas below it, so that the flue gas quickly passes through the filter plate 32, and can press the flue gas into the liquid collection cylinder 13, so that the liquid medicine in the liquid collection cylinder 13 performs secondary biocatalysis on the flue gas, thereby preventing the liquid medicine in the liquid collection cylinder 13 from blocking the flue gas, making it difficult for the flue gas to pass through the liquid collection cylinder 13 and affecting the purification effect.

[0054] When the dust and particles on the filter plate 32 and the filter cover 348 are accumulated to a certain amount, the opening and closing door 31 is opened, so that the opening and closing door 31 drives the filter plate 32 and the filter cover 348 at the lower end of the reciprocating plate 344 to be moved out of the air intake cylinder 11 as a whole (at Figure 6 As shown in the figure), the filter plate 32 and the filter cover 348 can then be removed to remove the dust and particulate matter on the upper end thereof and can be reused.

[0055] Reference Figure 2As shown, since the liquid collection cylinder 13 is filled with liquid medicine, when the flue gas in the air intake cylinder 11 is pressed downward into the liquid collection cylinder 13, the liquid medicine is easily squeezed into the exhaust cylinder 12, which not only affects the biocatalysis of the liquid medicine on the flue gas, but also easily causes the liquid medicine to overflow from the exhaust cylinder 12. In order to avoid the occurrence of this problem, a pressurizing component 34 is also provided in this embodiment. Specifically, the pressurizing component 34 also includes two circular fixing plates 350 respectively installed on the inner walls of the air intake cylinder 11 and the liquid collection cylinder 13, and the two circular fixing plates 350 are provided with exhaust holes corresponding to the positions, and a plurality of ventilation pipes 351 connected to the exhaust holes are installed between the two circular fixing plates 350; it should be noted that pillars (not shown in the figure) are installed between the circular fixing plates 350 and the inner walls of the air intake cylinder 11 and the liquid collection cylinder 13. The pillars can not only prevent the liquid medicine in the air intake cylinder 11 from flowing into the liquid collection cylinder 13, but also make the liquid medicine on both sides of the liquid collection cylinder 13 connected to each other.

[0056] During the specific implementation process, when the flue gas after spraying in the air intake cylinder 11 is pressed downward into the liquid collection cylinder 13, the flue gas passes through the circular fixed plate 350 in the air intake cylinder 11, the ventilation pipe 351 and the circular fixed plate 350 in the liquid collection cylinder 13 in turn, and then enters the liquid collection cylinder 13. Then, the flue gas passes through the liquid in the liquid collection cylinder 13 and enters the purification unit 4, so that the purification unit 4 adsorbs and filters the flue gas, and then the flue gas is discharged from the exhaust pipe 12, so as to facilitate the discharge of the sprayed and filtered flue gas into the liquid collection cylinder 13 for adsorption, filtration and biocatalysis, thereby enhancing the purification effect of the flue gas.

[0057] Reference Figure 4 As shown, in order to ensure that the smoke below the reciprocating plate 344 is pressed downward into the liquid accumulation cylinder 13 when it moves downward, based on this, in the present embodiment, an air intake check valve 111 is installed at the upper end of the air intake cylinder 11, and the sealing plate 347 includes a plurality of fan-shaped plates 352 which are rotatably arranged on the inner wall of the through hole 346 by a torsion spring, and a plurality of blocks 353 corresponding to the positions of the fan-shaped plates 352 are installed on the inner wall of the through hole 346, and the block 353 is located above the fan-shaped plate 352, and the top of the fan-shaped plate 352 is in conflict with the block 353.

[0058] It should be noted that the air intake check valve 111 used in this embodiment can only allow external smoke to be discharged into the air intake cylinder 11, and cannot allow the smoke in the air intake cylinder 11 to overflow, thereby facilitating the smoke in the smoke outlet of the electric furnace to be discharged into the air intake cylinder 11 through the air intake check valve 111; in addition, the torsion spring always applies an upward torsional force to the fan plate 352, so that the fan plate 352 rests against the bottom of the block 353 under the action of the torsional force.

[0059] During the specific implementation process, when the reciprocating plate 344 moves upward, it drives the fan plate 352 to move synchronously, so that the distance between the reciprocating plate 344 and the inner top wall of the air intake cylinder 11 gradually decreases, so that the fan plate 352 is squeezed by the smoke above the reciprocating plate 344 and adaptively rotates downward and opens the through hole 346, so that the smoke above the reciprocating plate 344 passes through the through hole 346 and enters the bottom of the reciprocating plate 344. During this period, the smoke above the air intake cylinder 11 will not overflow to the outside due to the action of the intake check valve 111.

[0060] Subsequently, the reciprocating plate 344 moves downward and the distance between it and the inner top wall of the air intake cylinder 11 gradually increases, so that the fan-shaped plate 352 is no longer squeezed by the smoke above the reciprocating plate 344 and resets to restore the closure of the through hole 346 under the action of the torsion spring, thereby facilitating the reciprocating plate 344 to cooperate with the sealing plate 347 to squeeze the smoke below it downward into the liquid collection cylinder 13, thereby speeding up the efficiency of pressing the smoke in the air intake cylinder 11 into the liquid collection cylinder 13.

[0061] Embodiment 2:

[0062] Reference Figure 7 and Figure 8 As shown, on the basis of Example 1, in order to further remove volatile substances and harmful gases in the flue gas, it is necessary to perform corresponding biocatalysis and adsorption filtration on the flue gas. Based on this, a purification unit 4 is also provided in this embodiment. Specifically, the purification unit 4 also includes a mounting hole opened at the upper end of the liquid collection cylinder 13, and a sealing door 42 is rotatably provided on the side wall of the mounting hole. A mounting cylinder 43 with two ends passing through is installed on the inner wall of the liquid collection cylinder 13, and an activated carbon filter element 41 is movably arranged in the mounting cylinder 43. One end of the mounting cylinder 43 is abutted against the circular fixed plate 350 in the liquid collection cylinder 13, and a diverter plate 44 is provided at the other end. The diverter plate 44 is connected to the inner wall of the liquid collection cylinder 13.

[0063] Furthermore, in this embodiment, the mounting tube 43 is composed of an arc-shaped positioning plate 45 and an arc-shaped disassembly plate 46, wherein the arc-shaped positioning plate 45 is installed on the inner bottom wall of the liquid collection tube 13, and the arc-shaped disassembly plate 46 is installed on the upper end of the arc-shaped positioning plate 45 in a detachable manner.

[0064] In the specific implementation process, the sealing door 42 is first opened, and then the activated carbon filter element 41 is placed on the arc-shaped positioning plate 45, and then the arc-shaped disassembly plate 46 is installed on the arc-shaped positioning plate 45, and finally the sealing door 42 is closed; when the smoke after spraying and filtering passes through the exhaust hole on the circular fixed plate 350 and then passes through the activated carbon filter element 41, the smoke can be filtered by the activated carbon filter element 41, which can not only filter out the reactants generated after contact with the liquid medicine, but also remove volatile substances and harmful gases in the smoke by adsorption filtration. Then the smoke passes through the diverter plate 44 and enters the exhaust pipe 12 (at Figure 7As shown in the figure), the flue gas can be further purified by the liquid medicine in the exhaust pipe 12 so as to completely remove the harmful gases in the flue gas; thereby, the flue gas can be double filtered by the activated carbon filter element 41 in combination with the liquid medicine, thereby achieving comprehensive purification of the flue gas.

[0065] It should be noted that the diverter plate 44 is provided with a plurality of outlet holes for smoke to pass through, and the diameter of the outlet holes is smaller than the diameter of the exhaust hole; therefore, when the smoke passes through the diverter plate 44 and is discharged into the exhaust pipe 12, the smoke is discharged through the outlet holes, so that the smoke slowly enters the exhaust pipe 12, thereby preventing the smoke from filling the exhaust pipe 12 and causing the liquid medicine inside to overflow.

[0066] During operation: Step 1: First, connect the smoke outlet of the electric furnace with the air inlet 11 , and then the smoke in the electric furnace enters the air inlet 11 .

[0067] Step 2: When the flue gas enters the air inlet cylinder 11, the water pump 24 is started, and the water pump 24 discharges the liquid medicine in the liquid collection cylinder 13 into the annular cylinder 22. Then the spray head 21 sprays the liquid medicine in the annular cylinder 22 and sprays the flue gas. This can not only reduce the dust generated during the purification process of the flue gas, so that the particles in the flue gas adhere to the liquid medicine on the surface and quickly settle downward, thereby accelerating the purification efficiency, but also can preliminarily catalyze the harmful substances in the flue gas through the liquid medicine, so as to enhance the purification effect of the flue gas.

[0068] The third step: start the driving motor 343, the driving motor 343 drives the bidirectional screw 342 to rotate, the bidirectional screw 342 drives the reciprocating plate 344 to move up and down, and the reciprocating plate 344 drives the fan plate 352 to move synchronously when moving up, so that the distance between the reciprocating plate 344 and the inner top wall of the air intake cylinder 11 is gradually reduced, so that the fan plate 352 is squeezed by the smoke above the reciprocating plate 344 and adaptively rotates downward and opens the through hole 346. The smoke in the air intake cylinder 11 passes through the through hole 346 and enters the bottom of the reciprocating plate 344. At this time, the smoke after spraying can be preliminarily filtered through the filter cover 348.

[0069] Subsequently, the reciprocating plate 344 moves downward and the distance between it and the top wall of the air inlet cylinder 11 gradually increases, so that the fan-shaped plate 352 is no longer squeezed by the flue gas above the reciprocating plate 344 and resets to restore the closure of the through hole 346 under the action of the torsion spring, so that the reciprocating plate 344 cooperates with multiple sealing plates 347 to press down the flue gas below it, so that the flue gas quickly passes through the filter plate 32, and can press the flue gas into the liquid collection cylinder 13, so that the liquid medicine in the liquid collection cylinder 13 performs secondary biocatalysis on the flue gas, thereby preventing the liquid medicine in the liquid collection cylinder 13 from blocking the flue gas, making it difficult for the flue gas to pass through the liquid collection cylinder 13 and affecting the purification effect.

[0070] Step 4: When the flue gas after spraying in the air intake cylinder 11 is pressed downward into the liquid collection cylinder 13, the flue gas passes through the circular fixed plate 350 in the air intake cylinder 11, the ventilation pipe 351 and the circular fixed plate 350 in the liquid collection cylinder 13 in turn, and then enters the liquid collection cylinder 13, and then the flue gas passes through the activated carbon filter element 41. The activated carbon filter element 41 can filter the flue gas, which can not only filter out the reactants produced after contact with the liquid medicine, but also remove volatile substances and harmful gases in the flue gas by adsorption filtration.

[0071] Then, the smoke passes through the diverter plate 44 and enters the exhaust pipe 12. The smoke can be further purified by the liquid medicine in the exhaust pipe 12, so as to completely remove harmful gases in the smoke.

[0072] Step 5: When the dust and particulate matter on the upper ends of the filter plate 32 and the filter cover 348 accumulate to a certain amount, open the opening and closing door 31 so that the opening and closing door 31 drives the filter plate 32 and the filter cover 348 at the lower end of the reciprocating plate 344 to be moved out of the air intake cylinder 11 as a whole, and then the filter plate 32 and the filter cover 348 can be removed to remove the dust and particulate matter on the upper ends thereof so that they can be reused.
