Description

Technical Field

[0001] The invention relates to the technical field of combustible gas purification, and in particular to a deacidification and dust removal device and a control method thereof. Background Art

[0002] Garbage pyrolysis and gasification refers to the process in which the macromolecules of organic components in garbage break down under oxygen-free or oxygen-deficient conditions to produce small molecular gases, tar and residues. Garbage pyrolysis and gasification technology not only achieves the harmlessness, reduction and resource utilization of garbage, but also effectively overcomes the dioxin pollution problem caused by garbage incineration, thus becoming a garbage treatment technology with great development prospects. However, garbage pyrolysis and gasification contains HCL and a large amount of fine particles. Among the requirements for combustible gas in internal combustion engine power generation systems, the particulate matter needs to be less than 15mg / Nm 3 , HCL content is less than 50mg / Nm 3 At present, the traditional method of deacidification and dust removal of combustible gas adopts a combination of cyclone dust collector, bag dust collector, deacidification equipment, etc. to achieve deacidification and dust removal. However, since the bag dust collector limits the dust removal temperature, the gas needs to be reduced to about 300°C. This process will consume a large amount of sensible heat of the gasification gas, reducing the heat utilization rate. Summary of the invention

[0066] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0067] Example 1

Figure 1 The vertical upward direction indicated by the middle dotted arrow flows through the dust collector body 11, the ceramic fiber tube 12 is arranged in the dust collector body 11, the deacidifying agent adding mechanism has an adding port connected to the dust collector body 11, and the adding port is located upstream of the ceramic fiber tube 12, the ash bin 14 is connected to the dust collector body 11 and is located below the ceramic fiber tube 12, and the inert gas backflush system 15 has a backflush port connected to the dust collector body 11, and the backflush port is located above the ceramic fiber tube 12.

[0069] In the deacidification and dust removal device, the addition port of the deacidification agent addition system 1 adds the deacidification agent into the dust collector body 11 from the upstream of the ceramic fiber tube 12, uniformly mixes and reacts with the combustible gas, and then adheres to the outer wall surface of the ceramic fiber tube 12 to react again, thereby achieving the goal of secondary reaction and greatly improving the deacidification efficiency of the combustible gas.

[0070] At the same time, by setting up an inert gas backflush system 15, nitrogen is blown into the ceramic fiber tube 12 through the backflush port located above the ceramic fiber tube 12, and the reacted deacidifying agent attached to the surface of the ceramic fiber tube 12 is discharged into the ash bin 14 under the action of the inert gas backflush system 15, thereby realizing the collection of ash.

[0071] The combustible gas flows through the dust collector body 11 in an upward direction, which is opposite to the falling direction of the ash on the surface of the ceramic fiber tube 12, so as to prevent the ash after the reaction from flowing out together with the combustible gas.

[0072] Therefore, the deacidification and dust removal device can achieve high-temperature deacidification and dust removal, avoid the loss of sensible heat of the gasification gas, and improve the heat utilization rate of subsequent processes.

[0073] In addition, if Figure 1 As shown, the deacidification and dust removal device also includes an image acquisition unit and a control mechanism 3. The camera 2 of the image acquisition unit is arranged in the dust collector body 11, and the control mechanism 3 is used to obtain the image taken by the image acquisition unit, and control the amount of deacidification agent added by the deacidification agent addition system 1, the nitrogen flow rate of the inert gas backflush system 15, and the combustible gas flow rate in the dust collector body 11 based on the image.

[0074] The deacidification and dust removal device is provided with a camera 2 of an image acquisition unit near the addition port to acquire images, and analyzes the images through a control mechanism 3. Based on the analysis data, a parameter control amount is given to adjust the feed amount of the deacidification agent addition system 1, the nitrogen flow rate of the inert gas backflush system 15, and the combustible gas flow rate in the dust collector body 11. By coupling the nitrogen flow rate with the flow rate of the combustible gas, the mixing uniformity of the deacidification agent and the combustible gas is improved, thereby improving the deacidification efficiency.

[0075] Specifically, in this embodiment, the control mechanism 3 controls the amount of deacidifying agent added by the deacidifying agent adding system 1, the nitrogen flow rate of the inert gas backflush system 15, and the flow rate of the combustible gas in the dust collector body 11 based on the image. Of course, in other embodiments, the control mechanism 3 can also control one or two of the amount of deacidifying agent added by the deacidifying agent adding system 1, the nitrogen flow rate of the inert gas backflush system 15, and the flow rate of the combustible gas in the dust collector body 11 based on the image, so as to achieve the purpose of actively controlling the uniformity of the mixing of the deacidifying agent and the combustible gas.

[0076] The deacidification and dust removal device further includes a first cooling mechanism, which is arranged on the image acquisition unit to cool the camera 2 to prevent damage due to high temperature. Specifically in this embodiment, the first cooling mechanism is implemented by water cooling.

[0077] In addition, if Figure 1 As shown, the camera 2 in this embodiment is arranged near the addition port where the deacidification agent addition system 1 is connected to the dust collector body 11. Arranging the camera 2 of the image acquisition unit near the addition port and acquiring images can improve the correlation between the acquired image and the mixing uniformity of the deacidification agent and the combustible gas, realize more precise control of the control mechanism 3, and improve the deacidification efficiency.

[0078] In this embodiment, a preferred image processing scheme is provided, based on the image of the deacidification agent and the combustible gas in the dust collector body 11 taken by the camera 2, the mixing degree data of the deacidification agent and the combustible gas is analyzed, and the specific scheme of the deacidification agent feed amount, nitrogen flow rate, and combustible gas flow rate parameters is determined according to the analysis results. Specifically, after the multiple images taken by the camera 2 are averaged, the averaged image is gray-scale converted, and the gray-scale conversion can be performed using the following formula: Gray = 0.3*R+0*G+0.7*B, where Gray is the gray value, R is the red value, G is the green value, and B is the blue value. After that, the pixel point data in the frame image is analyzed, and the following division method can be used: the picture is divided into n*n grids, where n is a positive integer, and the gray value in each grid in the cross section is calculated respectively, and the gray value of each grid is used to determine the gray average of the averaged image, thereby quantifying and judging the mixing uniformity of the particulate solid and the combustible gas.

[0079] Of course, the solution provided above is only one of the specific implementation solutions. Other solutions existing in the prior art can also be used to analyze the image taken by the camera 2 to adjust one or more of the deacidifying agent addition amount of the deacidifying agent addition system 1, the nitrogen flow rate of the inert gas backflush system 15, and the combustible gas flow rate in the dust collector body 11 based on the captured image.

[0080] like Figure 1As shown, in this embodiment, the deacidifying agent adding system 1 includes a deacidifying agent silo 4, a screw conveyor 8 and a venturi injector 10. Among them, the deacidifying agent silo 4 is used to contain the deacidifying agent, the screw conveyor 8 is arranged at the bottom of the deacidifying agent silo 4, and the outlet of the venturi injector 10 is arranged on the dust collector body 11 to form an adding port, and the screw conveyor 8 is used to transport the deacidifying agent in the deacidifying agent silo 4 to the inlet of the venturi injector 10. By arranging the screw conveyor 8 to transport the deacidifying agent in the deacidifying agent silo 4 to the venturi injector 10, the purpose of quantitative transportation is achieved, which is conducive to improving the quantitative delivery of the deacidifying agent. At the same time, by arranging the venturi injector 10 to transport the deacidifying agent to the dust collector body 11, the venturi injector 10 is used to realize the premixing of the deacidifying agent, and the mixing efficiency of the deacidifying agent and the combustible gas is improved.

[0081] Specifically, the deacidification agent adding system 1 also includes a rotary level meter 5, an air hammer 6, a discharge valve 7 and an air lock 9. The rotary level meter 5 is used to transport the deacidification agent to the deacidification agent silo 4 to control the amount of the deacidification agent added. The air hammer 6 is arranged on the outer surface of the deacidification agent silo 4, and the air hammer 6 is started at intervals to prevent the deacidification agent from adhering to the wall of the deacidification agent silo 4 and being unable to fall.

[0082] The screw conveyor 8 is connected to the bottom of the deacidifying agent silo 4 through the discharge valve 7. At the same time, the screw conveyor 8 is connected to the inlet of the venturi injector 10 through the air lock 9. The deacidifying agent is quantitatively transported by the screw conveyor 8, and is carried by nitrogen into the dust collector body 11 after passing through the air lock 9 and the venturi injector 10. Specifically, the screw conveyor 8 in this embodiment is driven by a servo motor to improve the quantitative transport capacity.

[0083] like Figure 1 As shown, the deacidification and dust removal device also includes a butterfly valve 13, and the ash bin 14 is connected to the dust collector body 11 through the butterfly valve 13. Specifically in this embodiment, the butterfly valve 13 is a high-temperature pneumatic butterfly valve to achieve normal opening and closing in a high-temperature environment. In addition, the deacidification and dust removal device also includes a second cooling mechanism, which is arranged at the ash bin 14. By setting the cooling mechanism, the ash in the ash bin 14 is cooled, which is conducive to the ash being discharged by subsequent other devices after cooling. Specifically in this embodiment, the second cooling mechanism is realized by water cooling.

[0084] Specifically in this embodiment, the combustible gas is in the vertical upward direction ( Figure 1 The combustible gas flows through the dust collector body 11 in the direction indicated by the dashed arrow in the middle. By making the combustible gas flow through the dust collector body 11 in the vertical upward direction, the flow direction of the combustible gas is completely opposite to the falling direction of the ash, so as to further prevent the ash after the reaction from flowing out together with the combustible gas. Of course, in other embodiments, the channel arrangement in the dust collector body 11 can also make the combustible gas flow in an inclined upward direction, and the specific flow direction can be set according to actual needs.

[0085] like Figure 2 As shown, the present invention also provides a control method for a deacidification and dust removal device, the control method comprising the following steps:

[0086] S1. The deacidifying agent is transported into the dust collector body 11 through the adding port by the deacidifying agent adding system 1, and is mixed with the combustible gas in the dust collector body 11 to react.

[0087] S2, the deacidifying agent and the combustible gas flow through the ceramic fiber tube 12 along the flow direction of the combustible gas, and adhere to the outer wall surface of the ceramic fiber tube 12 to react.

[0088] S3, blowing nitrogen to the ceramic fiber tube 12 through the back-blowing port of the inert gas back-blowing system 15, and discharging the ash attached to the surface of the ceramic fiber tube 12 into the ash bin 14.

[0089] The control method of the deacidification and dust removal device can realize high-temperature deacidification and dust removal, avoid the loss of sensible heat of gasification gas, and improve the heat utilization rate of subsequent processes.

[0090] Specifically, step S1 may include the following steps:

[0091] S11, taking an image of the mixture of the deacidifying agent and the combustible gas in the dust collector body 11, and analyzing the image to obtain data on the degree of mixing of the deacidifying agent and the combustible gas;

[0092] S12. Adjust at least one of the amount of deacidifying agent added, the flow rate of nitrogen, and the flow rate of combustible gas based on the mixing degree data.

[0093] The mixing degree data is obtained by analyzing the image, and the parameter control amount is given according to the analysis data to adjust the feed amount of the deacidifying agent addition system 1, the nitrogen flow rate of the inert gas backflush system 15, and the combustible gas flow rate in the dust collector body 11. By coupling the nitrogen flow rate with the flow rate of the combustible gas, the mixing uniformity of the deacidifying agent and the combustible gas is improved, thereby improving the deacidification efficiency.

[0094] Furthermore, step S11 specifically includes: using the formula Gray=0.3*R+0*G+0.7*B to convert the image into grayscale, and dividing the grayscale converted image into n*n grids, respectively calculating the grayscale value in each grid, using the grayscale value of each grid to determine the grayscale average of the grayscale converted image, and then obtaining the mixing degree data of the deacidification agent and the combustible gas based on the grayscale average. Of course, the above-mentioned scheme is only one of the specific implementation schemes, and other schemes existing in the prior art can also be used to analyze the image captured by the camera 2, so as to adjust one or more of the deacidification agent addition amount of the deacidification agent addition system 1, the nitrogen flow rate of the inert gas backflush system 15, and the combustible gas flow rate in the dust collector body 11 based on the captured image.
