Description

Technical Field

[0001] The invention relates to the technical field of tar separation equipment, and in particular to a coke adsorption device. Background Art

[0002] Coke oven flue gas contains a variety of harmful substances, such as particulate matter, sulfur dioxide, nitrogen oxides, etc. If these harmful substances are directly discharged into the atmosphere, they will cause serious pollution to the environment. The flue gas generated in the coke oven usually enters the bag filter through the smoke duct to treat the flue gas and purify the flue gas. This method can significantly reduce the emission of these harmful substances and protect the atmospheric environment.

[0003] However, in the actual production process, some tar will be mixed in the flue gas generated in the coke oven. Since tar has high viscosity, it is easy to form an adhesion layer on the filter bag of the bag collector after entering the bag collector. As time goes by, this adhesion layer will gradually thicken and cause the filter bag to be blocked, affecting the filtering and dust removal effect of the dust collector. In addition, the tar on the bag collector is difficult to deal with, and can only be replaced, which has high replacement costs.

[0004] To this end, the present invention provides a coke adsorption device. Summary of the invention

DETAILED DESCRIPTION

[0027] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0028] like Figures 1 to 8 As shown, a coke adsorption device according to an embodiment of the present invention is shown in Figure 1 , Figure 2 , Figure 4 , including a flue gas purification mechanism 3, the flue gas purification mechanism 3 includes a purification box assembly 304, the bottom of one side of the purification box assembly 304 is fixedly connected with an air inlet pipe 303, the top of the other side of the purification box assembly 304 is fixedly connected with an air outlet pipe 302, and a filter screen 6 is arranged in the middle of the inner side of the purification box assembly 304. When the flue gas enters the inner side of the purification box assembly 304 from the air inlet pipe 303, the flue gas passes through the filter screen 6 and the coke in the filter screen 6 absorbs the tar in the flue gas, and the flue gas treated by the filter screen 6 is discharged from the air outlet pipe 302 to the bag collector.

[0029] Specifically, a fan is installed on the other side of the exhaust pipe 302 to extract the flue gas and guide the direction of the flue gas entering from the air inlet pipe 303, so that the flue gas passes through the filter screen 6 and is filtered by the filter screen 6 and then discharged from the exhaust pipe 302. The filter screen 6 can absorb tar and large particles in the flue gas. At the same time, a purification box assembly 304 is provided to transfer the flue gas emission process, which can reduce the temperature of the flue gas entering the bag collector. Some sparks remaining in the flue gas under the high-pressure environment are blocked in the purification box assembly 304 to avoid directly entering the bag collector, thereby increasing the service life of the bag collector.

[0030] Please refer to Figure 5 The filter screen 6 includes a mesh body 601 , a charcoal storage compartment 604 is provided on the top of the mesh body 601 , the coke is placed inside the charcoal storage compartment 604 , a second filter hole 603 is provided on one side of the mesh body 601 , and a first filter hole 602 is provided on the other side of the mesh body 601 .

[0031] Specifically, the mesh body 601 divides the inner side of the box body 3041 into an air inlet cavity and an air outlet cavity. The flue gas enters the air inlet cavity from the air inlet pipe 303, and then passes through the filter screen 6 and enters the air outlet cavity under the guidance of the fan of the air outlet pipe 302. Among them, the inner diameter of the second filter hole 603 is larger than the outer diameter of large particles of impurities and smaller than the outer diameter of coke, ensuring that the flue gas carrying large particles of impurities can pass through the second filter hole 603 while preventing the coke from leaking out. When the flue gas enters the charcoal storage cabin body 604, the coke in the charcoal storage cabin body 604 will absorb tar and large particles of impurities to pre-treat the flue gas. The pre-treated flue gas is then discharged through the first filter hole 602 and then discharged from the air outlet pipe 302. The inner diameter of the hole of the charcoal storage cabin body 604 is smaller than the inner diameter of the hole of the second filter hole 603, which can intercept impurities in the flue gas pre-treated by coke again, thereby improving the filtering effect.

[0032] Please refer to Figure 4 The purification box assembly 304 includes a box body 3041 and a support plate 3044. The mesh body 601 is fixedly connected to the middle part of the box body 3041. One end of the support plate 3044 is fixedly connected to the outer wall of the mesh body 601, and the other end of the support plate 3044 is fixedly connected to the inner wall of the box body 3041. An air inlet 3042 is opened on one side of the box body 3041, and an air outlet 3043 is opened on the other side of the box body 3041. The air inlet 3042 is connected to the air inlet pipe 303, and the air outlet 3043 is connected to the air outlet pipe 302.

[0033] Specifically, Figure 4 As shown, the support plates 3044 support the outer side of the net body 601 , and the support plates 3044 are evenly distributed on both sides of the net body 601 , thereby improving the stability of the net body 601 fixed on the inner side of the box body 3041 .

[0034] Please refer to Figure 1 , Figure 2 , Figure 4 The present invention also includes a feeding structure 1, a transmission pipe 2 is arranged on the other side of the feeding structure 1, the bottom of the transmission pipe 2 is connected to the flue gas purification mechanism 3, a control component 5 for controlling unloading is arranged at the bottom of the flue gas purification mechanism 3, and a waste collection component 4 for receiving waste is arranged below the flue gas purification mechanism 3. When the adsorption efficiency of coke in the coke storage chamber 604 is insufficient, the control component 5 controls the used coke to be unloaded to the inner side of the waste collection component 4, and the feeding structure 1 controls the unused coke to pass into the filter screen 6 for replenishment.

[0035] Specifically, sensors are provided inside the air outlet duct 302 and the air inlet duct 303 to detect the quality of the flue gas after pretreatment and the quality of the flue gas without pretreatment, respectively. If the quality of the flue gas after pretreatment is significantly lower than that of the flue gas without pretreatment, the feeding structure 1 and the control component 5 are started to replace the coke in the filter screen 6 to ensure a stable pretreatment effect of the device.

[0036] Please refer to Figure 2 , Figure 4 , Figure 6 The flue gas purification mechanism 3 also includes a feed bin 301 and a discharge pipe 305. The feed bin 301 includes a feed pipe 3012. The top of the box body 3041 is provided with a mounting groove that matches the tolerance of the feed pipe 3012. The bottom of the feed pipe 3012 is fixedly connected to the top of the mesh body 601. The bottom of the box body 3041 is provided with a leakage hole that matches the tolerance of the outer side of the mesh body 601. The top of the discharge pipe 305 is fixedly connected to the bottom of the box body 3041.

[0037] Specifically, the protective shell 3011 , the transmission pipeline 2 , the carbon storage chamber 604 and the discharge pipeline 305 are interconnected, and the coke is located inside the feed pipeline 3012 , inside the discharge pipeline 305 and inside the carbon storage chamber 604 .

[0038] Please refer to Figure 4 , Figure 7 , Figure 8The control component 5 is installed at the bottom of the discharge pipe 305. The control component 5 includes a rotating shaft 502, which is rotatably connected to the bottom of the discharge pipe 305. A baffle 504 and an L-shaped stirring blade 505 are fixedly connected to the outer side of the rotating shaft 502. Four baffles 504 are provided, which are evenly distributed on the outer side of the rotating shaft 502 and the width of the baffles 504 is gap-matched with the inner width of the bottom of the discharge pipe 305. The sum of the length of the two baffles 504 and the outer diameter of the rotating shaft 502 is gap-matched with the inner length of the bottom of the discharge pipe 305. Two L-shaped stirring blades 505 are evenly distributed between two adjacent baffles 504. A servo motor 501 is fixedly connected to the back of the rotating shaft 502, and the output shaft of the servo motor 501 is fixedly connected to the back of the rotating shaft 502.

[0039] Specifically, Figure 8 As shown, this is the initial state of the control component 5, that is, the two baffles 504 on the same straight line just block the bottom outlet of the discharge pipe 305, and seal the coke at the top of the discharge pipe 305. At this time, the coke adsorption effect is in a normal state, wherein the angle between the two adjacent baffles 504 is ninety degrees, that is, the servo motor 501 is started and the bottom outlet of the discharge pipe 305 can be closed again every ninety degrees of rotation. The discharge amount can be set according to the filling amount inside the coke storage chamber 604 to avoid waste of coke in the subsequent unloading process, and when the rotating shaft 502 drives the outer baffle 504 and the L-shaped stirring blade 505 to rotate, since the L-shaped stirring blade 505 is L-shaped, it will stir the coke inside the discharge pipe 305 and push the coke downward when it rotates, so as to avoid the coke from getting stuck with each other and increase the unloading speed.

[0040] Please refer to Figure 2 , Figure 3 The waste collection component 4 includes a waste box 401, and the front and back sides of the top of the waste box 401 are fixedly connected to a mounting bracket 402, the back side of the servo motor 501 is fixedly connected to the mounting bracket 402 located at the back side, the front side of the rotating shaft 502 is rotatably connected to a mounting seat 503, and the front side of the mounting seat 503 is fixedly connected to the mounting bracket 402 located at the front side.

[0041] Specifically, the used coke discharged through the discharge pipe 305 is collected inside the waste box 401, the control component 5 is installed on the top of the waste collection component 4, the mounting frame 402 supports the control component 5 as a whole, and a bearing is provided at the connection between the mounting seat 503 and the rotating shaft 502. When the rotating shaft 502 rotates, the mounting seat 503 remains stationary.

[0042] Please refer to Figure 2The feeding structure 1 includes a bucket elevator body 101, a material bin is opened on the inner side of the bucket elevator body 101, a feed port 102 is arranged at the bottom of one side of the bucket elevator body 101, and a discharge port 104 is arranged at the top of the other side of the bucket elevator body 101. The feed port 102, the material bin of the bucket elevator body 101 and the discharge port 104 are interconnected. A driving motor 103 is installed on the back of the bucket elevator body 101, the discharge port 104 is interconnected with the transmission pipeline 2, and the bottom of the discharge port 104 is fixedly connected to the top of the transmission pipeline 2.

[0043] Specifically, when the driving motor 103 is started, the coke fed into the feed port 102 is lifted to the top and then discharged from the discharge port 104. The bucket elevator body 101 is a well-known technology, and the specific working principle is not described in detail.

[0044] Please refer to Figure 6 A protective shell 3011 is provided on the outside of the feed pipe 3012 for protection, and the top and bottom of the protective shell 3011 are fixedly connected to the bottom of the transmission pipe 2 and the top of the box body 3041 respectively; the protective shell 3011 protects the feed pipe 3012 to prevent the feed pipe 3012 from being worn by the outside and causing the coke transmission to be interrupted.

[0045] How it works When the device is used for the first time, the driving motor 103 is started to drive the coke filled in the feed port 102 to be lifted to the top, and then discharged from the discharge port 104, and then enters the transmission pipeline 2 through the discharge port 104. Since the protective shell 3011, the transmission pipeline 2, the coke storage chamber 604 and the discharge pipeline 305 are interconnected, the coke will be continuously transmitted to the inner side of the discharge pipeline 305 until the channel is filled; When the coke adsorption efficiency is in a normal state, that is, the two baffles 504 in the same straight line just block the bottom outlet of the discharge pipe 305, sealing the coke at the top of the discharge pipe 305, and the flue gas purification begins at this time; The fan of the air outlet pipe 302 extracts the flue gas, and the mesh body 601 divides the inner side of the box body 3041 into an air inlet cavity and an air outlet cavity. The flue gas passes into the air inlet cavity from the air inlet pipe 303, and then passes through the filter screen 6 and enters the air outlet cavity under the guidance of the fan of the air outlet pipe 302. In this process, the flue gas carrying large particles of impurities can pass through the second filter hole 603. When the flue gas enters the charcoal storage cabin body 604, the coke in the charcoal storage cabin body 604 will absorb tar and large particles of impurities to pre-treat the flue gas. The pre-treated flue gas is then discharged through the first filter hole 602 and then discharged from the air outlet pipe 302. The inner diameter of the hole of the charcoal storage cabin body 604 is smaller than the inner diameter of the hole of the second filter hole 603, so that the impurities of the flue gas pre-treated by the coke can be intercepted again. A sensor is provided on the inner side of the exhaust pipe 302 to detect the quality of the flue gas after pretreatment. If the quality of the flue gas after pretreatment is significantly reduced, the servo motor 501 is started to rotate first, and the servo motor 501 drives the rotating shaft 502 to rotate, and the rotating shaft 502 drives the outer baffle 504 and the L-shaped stirring blade 505 to rotate. When the L-shaped stirring blade 505 rotates, it will stir the coke inside the discharge pipe 305 and push the coke downward. The discharge amount is set according to the filling amount inside the coke storage chamber 604. The servo motor 501 can close the bottom outlet of the discharge pipe 305 again every ninety degrees of rotation. The total rotation degree of the servo motor 501 is controlled according to the filling amount inside the coke storage chamber 604, and ensure that the two baffles 504 on the same line are parallel to the bottom of the discharge pipe 305 when the servo motor 501 stops, that is, the bottom of the discharge pipe 305 is sealed, and then the drive motor 103 is started to fill the unused coke into the transmission pipe 2.

[0046] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
