DETAILED DESCRIPTION

[0022] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0023] In the present disclosure, unless otherwise specified, directional words such as "inside" and "outside" refer to the inside and outside relative to the outline of the structure or component itself; "first, second" and the like are intended to distinguish one element from another and have no order or importance. In addition, the same figure marks in different reference drawings represent the same elements.

[0024] The present invention provides a filtering device, referring to Figures 1 to 3As shown, the filtering device includes a pipeline 1, a guide plate 2 and a driving mechanism 3. The pipeline 1 includes a liquid channel 110 and a smoke channel 120 extending side by side along the extension direction of the pipeline 1 and a middle partition plate 4 separating the liquid channel 110 and the smoke channel 120. The liquid channel 110 is located above the smoke channel 120. The liquid channel 110 includes a first liquid inlet 111 and a first liquid outlet 112. The smoke channel 120 includes a smoke inlet 121 and a smoke outlet 122. The guide plate 2 runs through the liquid channel 110, the middle partition plate 4 and the smoke channel 120. The middle partition plate 4 has a first mounting hole 410 for the guide plate 2 to pass through. A flow channel is formed between the first mounting hole 410 and the guide plate 2. The flow channel is used to guide the medium flowing through the liquid channel 110 at least partially into the smoke channel 120. The driving mechanism 3 is connected to the guide plate 2. The driving mechanism 3 is used to drive the guide plate 2 to vibrate relative to the pipeline 1 to atomize at least part of the medium flowing through the flow channel.

[0025] Through the above-mentioned method, that is, the filtering device provided by the present invention, when adsorbing fly ash in the flue gas tail pipe, the flue gas can enter the flue gas channel 120 through the smoke inlet 121, and water or other media capable of adsorbing fly ash can be poured into the liquid channel 110 through the first liquid inlet 111. After entering the liquid channel 110, the water will pass through the flow channel between the guide plate 2 and the first mounting hole 410 from the liquid channel 110 into the flue gas channel 120, and some water will adhere to the surface of the guide plate 2 located in the flue gas channel 120. At this time, under the drive of the driving mechanism 3, the guide plate 2 will be driven to vibrate, and the medium flowing through the flow channel will be atomized under the vibration of the guide plate 2, so that the entire flue gas channel 120 can be densely covered with atomized medium, so as to increase the contact area with the fly ash in the flue gas channel 120 and improve the adsorption effect of the fly ash.

[0026] Furthermore, after the fly ash in the flue gas is adsorbed by the above-mentioned embodiment, the flue gas without fly ash or with a small amount of fly ash can continue to be discharged from the smoke outlet 122, thereby reducing the pollution of the flue gas to the environment. The redundant medium that has not adsorbed the fly ash can also be discharged from the first liquid outlet 112 for recycling, thereby reducing the waste of the medium. For example, the medium after adsorbing the fly ash, such as liquid, can flow through the liquid outlet into, for example, a desulfurization circulation pool or a desulfurization tower for desulfurization. The solid waste generated by desulfurization (such as CaSO 3) can react with oxygen to generate dihydrate gypsum, and then through dehydration and filtration, semi-solidified wet coal ash can be obtained. The wet coal ash can be reused for a second time, and the waste water after dehydration and filtration can be injected into the liquid channel again through the liquid inlet. Of course, fresh water can also be added through the liquid channel 110. Among them, the desulfurization process and dehydration and filtration are relatively mature existing processes in this field, and the present disclosure will not repeat them here. In addition, the smoke inlet 121 can be connected to the flue gas tail pipe, and the smoke outlet 122 can be connected to the flue gas treatment equipment in the auxiliary machine. For example, the smoke outlet 122 can be connected to the flue gas waste heat recovery heat exchanger or the flue gas waste gas recovery tower and other equipment for recovery and reuse. The present disclosure does not make specific limitations on this.

[0027] It should be noted that in the above embodiment, the liquid channel 110 needs to be located above the smoke channel 120. In this way, when the liquid medium in the liquid channel 110 is mixed with the smoke in the smoke channel 120, the liquid medium will be affected by gravity and flow into the smoke channel 120 faster for faster mixing. In addition, when the liquid medium passes through the flow channel, a liquid seal will be formed on the flow channel to prevent the smoke in the smoke channel 120 from floating into the liquid channel 110 above.

[0028] In some embodiments, reference Figures 1 to 3 As shown, the number of the first mounting holes 410 is multiple and arranged at intervals along the extension direction of the pipeline 1; the number of the guide plates 2 is multiple and the multiple first mounting holes 410 are pierced one by one. In this way, when water enters the liquid channel 110 through the first liquid inlet 111, it will pass through the multiple guide plates 2 in sequence and penetrate into the flue gas channel 120 through the flow channels between the multiple first mounting holes 410 and the guide plates 2, and when the multiple guide plates 2 are vibrated by the driving mechanism 3 at the same time, the contact area with the fly ash in the flue gas channel 120 is increased, that is, it can be referred to Figure 1 As shown, the following specific methods all use water as a medium to adsorb fly ash. When water enters the liquid channel 110 through the first liquid inlet 111, the water will first be evenly distributed in the liquid channel 110, and gradually penetrate into the flue gas channel 120 through the multiple flow channels formed between the multiple first mounting holes 410 and the multiple guide plates 2. During the penetration process, part of the water will also flow along the surface of the guide plate 2 to adhere to the lower half of the guide plate 2 located in the flue gas channel 120, and under the vibration of the multiple guide plates 2, the atomized water will be evenly distributed in the entire flue gas channel 120. When the flue gas enters from the smoke inlet 121, it can contact with the atomized water throughout the process, and then can adsorb the fly ash. The flue gas is then discharged from the smoke outlet 122, thereby improving the adsorption effect on the fly ash.

[0029] In some embodiments, reference Figures 1 to 3As shown, the filter device further includes a buffer block 420 circumferentially nested inside the first mounting hole 410, and a flow channel is formed between the buffer block 420 and the guide plate 2. In this way, the buffer block 420 can absorb the kinetic energy generated by at least part of the vibration of the guide plate 2 when the guide plate 2 vibrates, thereby preventing the guide plate 2 from directly hitting the first mounting hole 410 due to vibration, reducing the deformation of the first mounting hole due to the vibration of the guide plate 2, and the buffer block 420 can also play a certain supporting role for the water flowing through the liquid channel 110.

[0030] In some embodiments, reference Figures 1 to 3 As shown, the guide plate 2 is constructed as an M-type guide plate, and the flow channel includes a first flow channel 210 and a second flow channel 220, and the first flow channel 210 and the second flow channel 220 are respectively located on opposite sides of the M-type guide plate along the extension direction of the pipeline 1; the two side walls of the M-type guide plate opposite to the extension direction of the pipeline 1 are fitted with the buffer block 420, or, the two side walls of the M-shaped guide plate opposite to the extension direction of the pipeline 1 and the buffer block 420 have a third flow channel 230, and the flow channel includes the third flow channel 230. In this way, the first flow channel 210 and the second flow channel 220 can allow water to flow from the upper liquid channel 110 to the lower flue gas channel 120 to adsorb fly ash in the flue gas. Moreover, under the construction of the M-shaped guide plate, when water passes through the first flow channel 210 and the second flow channel 220, the contact area between the water and the guide plate 2 can be increased, thereby increasing the flow rate of water when passing through the first flow channel 210 and the second flow channel 220, thereby improving the efficiency of fly ash adsorption.

[0031] It should be noted that the above-mentioned embodiment can be used to connect the two opposite side walls of the M-shaped guide plate with the buffer block 420 in a manner of fitting together, that is, Figure 2 As shown in the effect, in this way, the liquid entering from the first liquid inlet 111 can flow into the smoke channel 120 through the first flow channel 210 and the second flow channel 220, and can flow into the next guide plate 2 from the gap between the inner wall of the pipe 1 and the opposite sides of the guide plate 2.

[0032] Alternatively, the third flow channel 230 may be provided between the M-shaped guide plate and the buffer block 420 in the above embodiment. Figure 3 In this arrangement, when water flows into the liquid channel 110 from the first liquid inlet 111, Figure 3Flowing in the direction of arrow X, the water will be divided into two streams when passing through the guide plate 2, one of which will be stopped by the guide plate 2 and pass through the first flow channel 210, that is, flow from the liquid channel 110 to the flue gas channel 120, and the other part will pass through the two third flow channels 230 on both sides to flow to the next guide plate 2, and can be diverted again at the next guide plate 2. In this flow mode, the water will flow through multiple guide plates 2 and pass through multiple guide plates 2 to the flue gas channel 120. In this way, the multiple guide plates 2 can not only transport water, but also attach a small amount of water to the surface of the multiple guide plates 2, and under the vibration action of the driving mechanism 3, the guide plates 2 are driven to vibrate to atomize the water, thereby improving the adsorption effect of fly ash.

[0033] In some embodiments, reference Figures 1 to 3 As shown, the pipeline 1 also includes an equipment chamber 130 located above the liquid channel 110, the guide plate 2 is partially located in the equipment chamber 130, and the driving mechanism 3 is located in the equipment chamber 130 and includes a vibration motor 310 and a connecting plate 320. The number of the vibration motors 310 is multiple and they are arranged at intervals along the extension direction of the pipeline 1; the connecting plate 320 is extended along the extension direction of the pipeline 1 and is connected to the multiple vibration motors 310 on one side and connected to the multiple guide plates 2 on the other side. In this way, when the guide plate 2 is required to vibrate and atomize the water, the multiple vibration motors 310 in the equipment chamber 130 can be used as driving parts to drive the connecting plate 320 to vibrate, and the vibration can be transmitted to the multiple guide plates 2 through the connecting plate 320 to atomize the water, that is, it can be referred to Figure 1 As shown, a plurality of vibration motors 310 are installed at intervals in the upper equipment chamber 130, a connecting plate 320 is arranged along the extension direction of the pipeline, and a plurality of guide plates 2 are vertically connected to the connecting plate 320. In this connection mode, the plurality of vibration motors 310 can increase the vibration amplitude of the connecting plate 320, and further increase the vibration amplitude of the guide plate 2, so as to be able to atomize more water and improve the adsorption efficiency of fly ash in the flue gas.

[0034] In some embodiments, reference Figures 1 to 3 As shown, an upper partition 5 is provided between the equipment chamber 130 and the liquid channel 110, and a plurality of second mounting holes 510 are arranged at intervals along the length direction of the pipeline 1 on the upper partition 5, and a plurality of second mounting holes 510 are pierced through the plurality of guide plates 2 in a one-to-one correspondence. In this way, the upper partition 5 can separate the equipment chamber 130 from the liquid channel 110, thereby preventing water entering the liquid channel 110 from entering the equipment chamber 130 and possibly causing a short circuit of the vibration motor 310. At the same time, the plurality of second mounting holes 510 can also be passed through by the plurality of guide plates 2, and the guide plates 2 can be stably connected to the connecting plate 320 after passing through the second mounting holes 510.

[0035] In addition, in order to prevent the guide plate 2 from hitting the second mounting hole 510 due to vibration, a buffer block can also be installed on the inner side of the second mounting hole 510. That is, referring to the method of installing the buffer block on the inner side of the first mounting hole 410 in the above-mentioned embodiment, the buffer block on the inner side of the second mounting hole 510 can also reduce the deformation of the second mounting hole 510 due to the vibration of the guide plate 2.

[0036] In some embodiments, reference Figure 1 As shown, in order to better stabilize the air pressure inside the pipeline 1, an air inlet 710 and an air outlet 720 can be set above the equipment chamber 130. The air inlet 710 can provide a positive pressure higher than the normal atmospheric pressure for the equipment chamber 130, thereby reducing the possibility of smoke in the smoke channel 120 or water in the liquid channel 110 entering the top equipment chamber 130, thereby improving the waterproof performance of the vibration motor 310 and the connecting plate 320 in the equipment chamber 130. In addition, the purpose of heat dissipation for the vibration motor can also be achieved through the air inlet 710 and the air outlet 720.

[0037] In some embodiments, reference Figures 1 to 3 As shown, the filtering device further includes a waste liquid flow channel 140 located below the flue gas channel 120, and the waste liquid flow channel 140 includes a second liquid inlet 141 and a second liquid outlet 142. In this way, the waste liquid flow channel 140 can discharge the fly ash adsorbed by water in the flue gas channel 120, that is, it can refer to Figure 1 As shown, when water passes from the liquid channel 110 to the flue gas channel 120 through the guide plate 2, the water will adsorb the fly ash in the flue gas, and the water-containing dust particles after adsorption will fall due to the gravity of the water. The water-containing dust particles after falling will enter the waste liquid flow channel 140 and be discharged along the second liquid outlet 142. Under this arrangement, the filter device can have a certain self-cleaning function, and when the second liquid inlet 141 and the second liquid outlet 142 are both set, the filter device can be connected to other water circulation systems in the flue, thereby improving the circulation function of the filter device.

[0038] In some embodiments, reference Figures 1 to 3 As shown, a lower baffle 6 is provided between the flue gas channel 120 and the waste liquid flow channel 140, and a plurality of third mounting holes 610 are arranged at intervals along the length direction of the pipeline 1 on the lower baffle 6, and a plurality of third mounting holes 610 are correspondingly penetrated in a plurality of guide plates 2. In this way, the guide plate 2 can pass through the third mounting holes 610 of the lower baffle 6 and extend into the waste liquid flow channel 140, that is, the length of the guide plate 2 is extended, and the contact area between the guide plate 2 and the flue gas can be increased, thereby increasing the adsorption amount of coal fly ash in the flue gas.

[0039] In some embodiments, reference Figures 1 to 3 As shown, an escape space 611 is provided between the third mounting hole 610 and the guide plate 2, and the escape space 611 is used to avoid the vibration of the guide plate 2 and to guide at least part of the medium in the flue gas channel 120 to flow into the waste liquid channel 140. In this way, when the guide plate 2 vibrates and atomizes the water flowing into the flue gas channel 120, the escape space 611 can leave a certain vibration margin for the vibration of the guide plate 2, so as to prevent the guide plate 2 from hitting the third mounting hole 610 when vibrating, and when the water flowing into the flue gas channel 120 merges with the fly ash, the escape space 611 can also discharge this part of the water into the waste liquid channel 140 more quickly, that is, improve the efficiency of the filter device in discharging waste water.

[0040] In some embodiments, reference Figures 1 to 3 As shown, the smoke outlet 122 extends in a direction away from the pipe 1, and a filter 1221 and an inclined surface 1222 are provided in the smoke outlet 122, and the inclined surface 1222 gradually rises from one end of the smoke outlet 122 close to the pipe 1 toward the other end away from the pipe 1. In this way, the filter 1221 of the smoke outlet 122 can reduce the humidity of the smoke when it is discharged from the smoke outlet 122, so that the drier smoke can be discharged from the smoke outlet 122, thereby preventing the smoke containing water and adsorbing fly ash from being discharged from the smoke outlet 122, so as to reduce the degree of pollution to the environment, and when the water containing fly ash is about to be discharged from the smoke outlet 122, it will also flow back into the smoke channel 120 due to the existence of the inclined surface 122 and slowly flow into the waste liquid flow channel 140, so as to prevent the sewage from flowing out.

[0041] The present disclosure exemplarily describes the filtering process of the filtering device, which may include the following steps:

[0042] The flue gas flows in the flue gas channel 120 at the bottom, and the filtered water circulates in the liquid channel 110 at the top. The filtered water is guided to the flue gas channel 120 through the first flow channel 210 and the second flow channel 220 of the guide plate 2, and is mixed with the flue gas containing fly ash in the flue gas channel 120, and the fly ash is adsorbed. The adsorbed water flows into the waste liquid flow channel 140 along the avoidance space 611 for circulation. In the process of water flowing along the guide plate 2, the vibration motor 310 continuously vibrates the connecting plate 32 0 vibrates, and transmits the vibration to the multiple guide plates 2, so that the multiple guide plates 2 vibrate together. In this process, water attached to the guide plates 2 will be atomized by the vibration of the guide plates 2, and the atomized water will contact the fly ash in a larger area in the smoke channel 120. Moreover, when the smoke flows through the smoke channel 120, the filter screen 1221 will reduce the humidity of the smoke discharged from the smoke outlet 122, and can return the water containing the fly ash to the waste liquid flow channel 140 through the inclined surface 1222.

[0043] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0044] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
