Description

TECHNICAL FIELD

[0001] The present application relates to the field of flue gas treatment, in particular to a black process adsorption device and method for asphalt flue gas. BACKGROUND

[0002] It is known that black process adsorption is a method for treating flue gas to remove harmful substances such as asphalt tar and benzopyrene in the flue gas. The process is as follows: after the calcination flue gas is treated by spraying and cooling, it enters the black process adsorption reactor to undergo an adsorption reaction with the added coke powder. After the reaction, the flue gas is sent to the black process adsorption dust collector for gas-solid separation. The separated flue gas is sent to the subsequent RTO system for further purification treatment before being discharged into the atmosphere. The dust particles separated by the black process adsorption dust collector are collected in the powder bin by shaking and are used as packing material after being made into balls. (See the Chinese patent document with the authorization publication number CN115105923A and the publication date of 2022-09-27, and the name of “A calcination furnace flue gas black process adsorption device and method”), and the black process adsorption dust collector is preferably a bag-type dust collector to remove solid impurities in the flue gas.

[0003] As shown in the Chinese patent document with the authorization publication number CN207153312U and the publication date of 2018-03-30, and the name of “A dust cleaning device for a bag-type dust collector and a bag-type dust collector”, a set of dust cleaning device composed of a sine linkage mechanism, a translation main beam, a connecting rod and a swing rod is arranged between the bags of the bag-type dust collector. The sine linkage mechanism drives the translation main beam to move left and right on the horizontal plane, so that the connecting rod connected to the translation main beam also moves left and right on the horizontal plane, thereby driving the swing rod fixed to the connecting rod to swing left and right to hit the bags from both sides of the bags, so that the dust adhering to the bags is shaken off by the external force.

[0004] The existing technology includes three ways to clean the bags. The first one is pulse cleaning, which has strong force and is easy to damage the bags and cause secondary adhesion of dust. The second one is reverse blowing, which has weak cleaning effect. The third one is manual beating. The existing technology uses a sine linkage to control the swing of the swing rod to beat the bags and achieve dust cleaning. However, the bags have a cage inside for internal support, which limits the deformation of the bags to a small range during the swing of the swing rod, thus greatly reducing the dust cleaning effect. Moreover, the bags may be squeezed between the cage and the swing rod during the swing of the swing rod, which may cause the bags to be damaged. SUMMARY

[0040] With reference to Figures 1-15 The black law adsorption device for asphalt smoke provided by the embodiment of the present application comprises a shell 1 and a cloth bag (not shown) for dust removal arranged in the shell 1. The cloth bag is internally provided with a bag cage 2. The bag cage 2 is provided with a first support rod 3 fixedly arranged thereon and a second support rod 4 slidingly connected thereto.

[0041] The shell 1 is internally provided with a beating mechanism. The second support rod 4 is arranged in position corresponding to the beating mechanism. When the beating mechanism approaches the cloth bag, the second support rod 4 moves away from the beating mechanism.

[0042] Specifically, the shell 1 is provided with an air inlet, an air outlet and a discharge port, and a plurality of cloth bags are vertically arranged inside the shell 1, and the plurality of cloth bags are arranged in a matrix (as a group of cloth bags in a column or a row), in order to avoid the deformation of the cloth bags as much as possible, a bag cage 2 is arranged in each cloth bag, the bag cage 2 includes a top ring 6 and a bottom plate 7, and the top ring 6 and the bottom plate 7 are connected by a plurality of supporting rods, and in order to increase the strength of the bag cage 2, a reinforcing ring 5 is arranged between the plurality of supporting rods, when the flue gas is treated by dust removal, the flue gas enters the inside of the shell 1 from the air inlet, and then is discharged through the air outlet, the solid impurities in the flue gas are blocked outside the cloth bag, a part of which is attached to the outer wall of the cloth bag, and the other part falls to the inner bottom wall of the shell 1 and is discharged through the discharge port, when the bag type dust removal is carried out, the cloth bag is struck and dusted by controlling the swing of the swing rod (see the patent document with the authorized publication number CN115105923A), which is the prior art and will not be described here, one of the core innovations of the embodiment of the present application is that the bag cage 2 is arranged in the cloth bag, and the supporting rods inside the bag cage 2 are divided into the first supporting rod 3 fixedly connected and the second supporting rod 4 radially slidingly connected along the bag cage 2, for a single bag cage 2, there are six first supporting rods 3 and two second supporting rods 4, the two second supporting rods 4 are symmetrically arranged, and the positions of the second supporting rods 4 are correspondingly arranged with the positions of the striking mechanism, the hardness of the second supporting rod 4 is greater than that of the first supporting rod 3, and the radial dimension of the second supporting rod 4 is greater than that of the first supporting rod 3, which can be controlled to move back and forth by an electric push rod, the setting of the second supporting rod 4 at the edge of the bottom plate 7 supports the cloth bag inside when the flue gas is treated by dust removal, and when the cloth bag is struck and cleaned, the striking mechanism is controlled to move towards the cloth bag, at the same time, the second supporting rod 4 is controlled to move away from the striking mechanism, so as to realize the avoidance, and when the cleaning is completed, the second supporting rod 4 is controlled to move reversely to reset, so as to support the cloth bag inside again for the next dust removal, the benefits brought by this are that, first, when the second supporting rod 4 moves away from the striking mechanism, the striking mechanism can move a larger stroke, so that the deformation amplitude of the cloth bag is larger, so as to improve the cleaning effect, second, the cloth bag can be avoided to be clamped between the striking mechanism and the bag cage 2, so as to avoid the damage of the cloth bag as much as possible, and third, in the resetting process of the second supporting rod 4, the second supporting rod 4 will collide with the concave inner wall of the cloth bag to lift the cloth bag outward, so as to realize the effect of secondary cleaning.

[0043] Preferably, the beating mechanism comprises a transmission member 8 slidingly arranged on the shell 1 and a plurality of beating rods 9 arranged on the transmission member 8, and a power assembly for driving the transmission member 8 to reciprocate. Specifically, the transmission member 8 is two and symmetrically arranged about the shell 1, and each transmission member 8 comprises two horizontal rods 10 and a plurality of vertical rods 11, and the horizontal rods 10 are connected with the power assembly through the side wall of the shell 1, and the power assembly can also be preferably an existing reciprocating driving assembly such as an electric push rod. As for a single beating rod 9, it comprises three sets of cylindrical rods arranged vertically, and in order to reduce the movement stroke of the beating rod 9, each set of cylindrical rods comprises two cylindrical rods arranged in parallel, and the two cylindrical rods are respectively used for beating the two groups of bags adjacent thereto. The two ends of each set of two beating rods 9 are connected by two short rods to form a rectangular structure, and the two short rods are respectively fixedly connected with the two transmission members 8. The arrangement is to control the transmission member 8 to reciprocate by the power assembly during the dust removal, so as to drive the plurality of beating rods 9 to reciprocate synchronously. During the movement of the beating rod 9, the beating rod 9 will collide with the outer circumferential surface of the bag, so as to drive the bag to shake, thereby achieving the dust removal effect.

[0044] As an alternative to the above-mentioned electric push rod for controlling the transmission member 8 to reciprocate, the power assembly comprises a driving motor fixedly connected to the outer side wall of the shell 1 and a rotating member 39 connected with the output end of the driving motor (not shown), and the transmission member 8 is fixedly connected with a transmission groove 12, and the end of the rotating member 39 is slidingly connected with the transmission groove 12. Specifically, the driving motor is preferably a stepping motor, which is fixedly connected to the outer wall of the shell 1, and the end of the horizontal rod 10 of the transmission member 8 penetrates to the outside of the shell 1, the transmission groove 12 is arranged on the side of the horizontal rod 10, and the end of the rotating member 39 is provided with a pulley, which extends into the transmission groove 12 and is slidingly connected with the transmission groove 12. The arrangement is to control the rotating member 39 at the output end of the driving motor to rotate when dust removal is needed, so as to make the transmission member 8 reciprocate, and during the reciprocation, the pulley will reciprocate in the transmission groove 12 to adapt to the change of the vertical position of the transmission member 8, and the radius of rotation of the rotating member 39 is the reciprocating stroke of the transmission member 8 and the beating rod 9.

[0045] It should be noted that in the process of flue gas dust removal, the inner wall of the shell 1 will inevitably have some dust attached, and over time, the inner wall of the shell 1 will accumulate dust. Preferably, the number of groups of the beating rods 9 is greater than the number of groups of the cloth bags. Specifically, the cloth bags are preferably 6 groups, and correspondingly, the beating rods 9 have 7 groups, that is, the outer sides of the two groups of cloth bags at both ends are provided with beating rods 9, and the distance from the two groups of beating rods 9 to the inner wall of the shell 1 is slightly less than the maximum stroke of the beating rods 9 when moving. The purpose of such arrangement is that the middle groups of beating rods 9 will beat the cloth bags on both sides when moving left and right, so that the cloth bags have two stress areas, thereby improving the dust removal effect. During the reciprocating movement of the transmission member 8, the groups of beating rods 9 will move synchronously. As for the beating rod 9 at the leftmost end, when it moves to the right, it will beat the leftmost cloth bag to remove dust. When it moves to the left end of the stroke, it will collide with the inner wall of the shell 1, causing the shell 1 to vibrate as a whole, so that the dust attached to the inner wall of the shell 1 falls off, so as to avoid the accumulation of dust on the inner wall of the shell 1.

[0046] As part of the flue gas contains moisture, when the moisture and dust on the outer wall of the bag contact, will appear "dew" phenomenon, so that the permeability of the bag is greatly reduced, thus reducing the efficiency of dust removal, as another embodiment of the present application, the housing 1 inner wall is provided with opening limiting groove 13, the transmission part 8 is provided with movable groove 14, the rod 9 through the movable groove 14 and the limiting groove 13 sliding connection. Specifically, the short rod is provided with a rectangular cross section rectangular part 15, and the rectangular end is provided with a cylindrical part 16, the transmission groove 12 is opened on the vertical rod 11, in this embodiment, the rod 9 is not fixed with the transmission part 8, but through the movable groove 14 and the transmission part 8 through connection, the rectangular part 15 is located in the movable groove 14, and the width of the movable groove 14 is matched with the width of the rectangular part 15, so as to avoid the vertical rotation of the rod 9, the length of the movable groove 14 is greater than the width of the rectangular part 15, so that the rod 9 can be vertically moved in the movable groove 14, the limiting groove 13 is located at both ends of the rod 9, and the cylindrical part 16 is slidably connected with the limiting groove 13, and the number of limiting grooves 13 corresponds to the number of movable grooves 14, which includes a horizontal section 17 and two inclined sections 18 arranged at both ends of the horizontal section 17, the inclined section 18 can be inclined upward or downward, the setting of which is that when the rod 9 is not working, the rod 9 is located in the middle position of the limiting groove 13, that is, in the horizontal section 17, when the transmission part 8 moves horizontally, the rod 9 moves horizontally under the action of the horizontal limiting of the movable groove 14, when the cylindrical part 16 of the rod 9 enters the inclined section 18 from the horizontal section 17, the rod 9 moves horizontally and vertically along the movable groove 14, which has the advantages that, first, the rod 9 moves horizontally and downward, which can improve the vertical range of the rod 9, thereby improving the beating effect of the bag, second, when the rod 9 contacts the "dew" material on the surface of the bag, it can scratch the bag in the vertical direction, thereby passively scraping off part of the "dew" material attached to the surface of the bag.

[0047] As an alternative to the above-mentioned electric push rod driving the second support rod 4 to move horizontally, the housing 1 is provided with a mounting bracket 19, and the second support rod 4 is provided with a first connecting piece 20, and the transmission member 8 penetrates the mounting bracket 19 and is fixedly connected with the first connecting piece 20. Specifically, the first connecting piece 20 includes a first segment 21 and a second segment 22 that are slidably connected with each other, the second support rod 4 is located on the first segment 21, the first segment 21 is provided with an expansion slot 23, the second segment 22 is slidably connected with the expansion slot 23, the side wall of the expansion slot 23 is provided with a receiving groove 24, the size of the entrance of the receiving groove 24 is smaller than the size of the end face of the second segment 22, the second segment 22 abuts against the inner wall of the expansion slot 23, the first segment 21 and the second segment 22 are provided with a first spring 25, and the first spring 25 is located inside the receiving groove 24, one end of the first spring 25 is fixedly connected with the side wall of the receiving groove 24, and the other end of the first spring 25 is fixedly connected with the end of the second segment 22, the transmission member 8 is provided with a plurality of connecting rods 26, the connecting rods 26 and the second segment 22 are fixedly connected through a pin shaft or a bolt or the like connecting structure, and two first connecting pieces 20 are symmetrically arranged on a single bag cage 2, and the purpose of such arrangement is that when the rod 9 is not working, it is placed in the middle position of the horizontal segment 17, and the connecting rod 26 is arranged between the adjacent two first connecting pieces 20, when the bag cage 2 is installed, the first connecting piece 20 is placed in the notch of the connecting rod 26, and then the first connecting piece 20 and the connecting rod 26 are fixedly connected, when the bag is cleaned, in terms of the left movement of the rod 9, the end of the left second segment 22 will abut against the side wall of the expansion slot 23, thereby pushing the left second support rod 4 to move leftward synchronously to realize avoidance (at the same time, when the connecting rod 26 moves horizontally, the right second segment 22 will move leftward, and since the right first segment 21 and the second support rod 4 cannot move leftward under the limiting action of the top ring 6, the connecting rod 26 will pull the right second segment 22 to move leftward, and will stretch the right first spring 25 to adapt), so as to realize passive avoidance of the second support rod 4 during the bag cleaning process, when the left single beating is completed, the rod 9 will move rightward, during which the connecting rod 26 will make the left first segment 21 and the second support rod 4 move rightward under the pulling action of the second segment 22 and the first spring 25, so as to reset, and during the resetting of the second support rod 4, it will impact the bag from the inside to passively clean the bag, after the left bag is cleaned, the connecting rod 26 moves rightward, and the above steps are repeated to clean the bags on both sides.

[0048] Preferably, the mounting bracket 19 is provided with an avoidance hole 27 for horizontal movement of the connecting rod 26, and the width of the transmission member 8 is greater than the width of the avoidance hole 27. Specifically, the avoidance hole 27 has a plurality of avoidance holes, and the crossbar 10 of the transmission member 8 is arranged above the avoidance hole 27 and is attached to the avoidance hole 27 to block the top of the avoidance hole 27, so as to avoid dust entering above the mounting bracket 19 from the position of the avoidance hole 27.

[0049] It should be noted that the conventional bag cage 2 installation method is to directly insert the bag cage 2 into the inside, which makes the radial dimension of the bag cage 2 slightly smaller than the radial dimension of the cloth bag, and when the bag cage 2 is inserted into the cloth bag, the cloth bag is still in a relaxed state, and when the flue gas enters the inside of the shell 1, under the action of the pressure of the flue gas, the cloth bag and the bag cage 2 will be relatively rubbed, which is easy to cause the wear of the cloth bag. As another embodiment of the present application, the second support rod 4 is provided with a protruding portion 28. Specifically, in this embodiment, a virtual cylinder is formed between the top ring 6 and the bottom plate 7, and when the second support rod 4 is placed at the edge position of the bottom plate 7, the distance from the protruding portion 28 to the axis of the bottom plate 7 is greater than the radial dimension of the bottom plate 7, that is, the protruding portion 28 will protrude from the outer circumferential surface of the virtual cylinder. The setting of this is that when the bag cage 2 is installed, the second support rod 4 is placed at a position close to the axis of the bottom plate 7, at this time, the second support rod 4 is accommodated in the inside of the virtual circle, so as to insert the bag cage 2 into the cloth bag, when the bag cage 2 is completely inserted into the cloth bag, the second section 22 is pulled to make the second section 22 slide towards the direction of the connecting rod 26 and connect the second section 22 with the connecting rod 26, during which the first section 21 and the second support rod 4 will be moved away from the axis of the bottom plate 7, so that the protruding portion 28 protrudes from the outer circumferential surface of the virtual circle and makes the protruding portion 28 abut with the inner circumferential surface of the cloth bag to support from the inside of the cloth bag, so that the cloth bag is in a taut state, thereby avoiding the mutual friction between the cloth bag and the bag cage 2 as much as possible, so as to improve the service life of the cloth bag.

[0050] In order to solve the above problems, preferably, the first connecting piece 20 is provided with a wedge surface 29, the connecting rod 26 is provided with an abutting rod 30, and the abutting rod 30 is located on the movement stroke of the first connecting piece 20. Specifically, the wedge surface 29 is arranged on the lower surface of the second section 22, and a flexible positioning groove is arranged at the end of the wedge surface 29. The abutting rod 30 and the connecting rod 26 are provided with a through hole. In this way, when the bag cage 2 is installed, the second support rod 4 is first arranged inside the virtual circle, and the position of the wedge surface 29 is arranged corresponding to the position of the abutting rod 30, and then the bag cage 2 is inserted downward. During this period, the wedge surface 29 on the second section 22 abuts against the abutting rod 30. In this way, the second section 22, the first section 21 and the second support rod 4 are passively moved away from the central axis of the bottom plate 7, so as to passively switch the position of the second support rod 4. When the wedge surface 29 abuts against the abutting rod 30, the abutting rod 30 enters the flexible positioning groove and is prevented from moving horizontally by the flexible positioning groove, so as to facilitate the subsequent pin connection or screw connection process.

[0051] Further, the bag cage 2 is provided with a sliding seat 31, the second support rod 4 is provided with a second connecting piece 32, and the second connecting piece 32 is in sliding connection with the sliding seat 31. Specifically, the sliding seat 31 is arranged on the inner bottom wall of the bottom plate 7, and a transverse groove is arranged in the sliding seat 31. A second spring 33 is arranged between the side wall of the transverse groove and the second connecting piece 32. The second connecting piece 32 is arranged at the bottom end of the second support rod 4 and is in sliding connection with the transverse groove, so as to provide a fulcrum for the bottom end of the second support rod 4, thereby improving the stability of the second support rod 4 during sliding. When the second support rod 4 moves towards the central axis of the bottom plate 7, the second spring 33 is charged. When the second support rod 4 moves reversely, the elastic force of the second spring 33 is released, so as to assist the second support rod 4 to reset.

[0052] As Figures 13-15As shown, the range acted by the baton 9 is the first area 34, and the range acted by the arc-shaped plate 38 is the second area 35, since the effect of the baton 9 on the second area 35 is less than the effect of the baton 9 on the first area 34, which makes the dust cleaning effect of the bag of the second area 35 poor. As another embodiment of the present application, the first supporting rod 3 is provided with a rotating ring 36, and a torsional spring (not shown) is arranged between the rotating ring 36 and the first supporting rod 3, the rotating ring 36 is fixedly connected with a rotating rod 37 and an arc-shaped plate 38, and the rotating rod 37 is located on the movement stroke of the second supporting rod 4. Specifically, the first supporting rod 3 close to the second supporting rod 4 is provided with not less than one rotating ring 36, and a limiting structure for preventing the relative axial movement between the rotating ring 36 and the first supporting rod 3 is arranged, such as a groove or a convex ring, the rotating rod 37 is arranged along the radial direction of the rotating ring 36, and adjacent two rotating rods 37 are arranged staggered in the vertical direction, the arc-shaped plate 38 is fixedly connected to the outer circumferential surface of the rotating ring 36, the elastic force of the torsional spring limits the rotating rod 37 on the movement stroke of the second supporting rod 4, and makes the arc-shaped plate 38 arranged at a position away from the second area 35, and the second area 35 is located on the rotating stroke of the arc-shaped plate 38. The arrangement has the following effects: when the bag is cleaned, the second supporting rod 4 slides towards the direction of the rotating rod 37, and the second supporting rod 4 abuts against the rotating rod 37, so that the rotating ring 36 is driven to rotate by the rotating rod 37, and then the arc-shaped plate 38 is driven to rotate towards the direction of the second area 35 and collides with the second area 35, so as to beat the second area 35 and store the elastic force of the torsional spring, thereby passively improving the dust cleaning effect of the second area 35. When the bag cleaning is completed, the second supporting rod 4 reversely slides, so that the second supporting rod 4 is away from the rotating rod 37, and the elastic force of the torsional spring is released to drive the arc-shaped plate 38 and the rotating ring 36 to reversely rotate and reset, for the next dust cleaning.
