Description

Technical Field

[0001] The invention belongs to the technical field of industrial tail gas treatment, and in particular relates to a three-salt micron dust removal device. Background Art

[0002] As the country's environmental protection requirements become increasingly stringent, the treatment of tail gas generated in the production process of the lead salt industry has become a focus of attention. This has promoted the technological innovation and equipment development for the treatment of tail gas in the production of tribasic lead sulfate. With the advancement of science and technology, new technologies and equipment have been widely used in many fields. In this context, the development of high-efficiency spray dust collectors, reducing operating costs and improving equipment performance has become a consensus in the industry.

[0003] The tail gas produced by the production of tribasic lead sulfate in the three-salt workshop is produced by the induced draft fan and then reaches the outside. After the exhaust gas is removed by a bag filter, it is further treated by a spray dust collector. The tail gas is filtered and adsorbed by the filler in the spray dust collector. The existing filler is provided with one layer. After the tail gas treatment does not meet the standard, it needs to be replaced as a whole. However, since the tail gas passes from the lower part of the filler to the upper part, the lower part of the filler is much more polluted than the upper part. The upper filler can still meet the work requirements. If the overall replacement is performed, the filler is not fully utilized, which increases the production cost. In this regard, the present invention arranges the filler section in layers and arranges a multi-layer filler mechanism. When the tail gas emission does not meet the standard, the filler mechanism of the bottom layer is taken out, and the upper filler mechanism slides down accordingly, and a new filler mechanism is re-inserted from the top. It not only meets the treatment requirements of the tail gas, but also prolongs the service life of the filler, greatly reduces the production cost, and improves the economic benefits of the enterprise. Summary of the invention

[0006] As an embodiment of the present invention, a plurality of insertion holes are evenly arranged on the side wall of the dust collection tube below the upper placement opening, and latches are arranged in the insertion holes; an openable and closable transparent visual door is arranged on the side wall of the dust collection tube between the two placement openings.

[0007] As an implementation manner of the present invention, the limiting groove is a spherical groove, and a gravity ball corresponding to the limiting groove is fixedly provided at the free end of the suspension rod.

[0008] As an embodiment of the present invention, the gravity ball includes a lead ball located in the middle and a corrosion-resistant layer wrapped around the outside of the lead ball.

[0009] As an embodiment of the present invention, the side wall of the dust collector is respectively fixed with an annular upper connecting plate and a lower connecting plate above and below the placement opening, and a telescopic sleeve is connected between the upper connecting plate and the lower connecting plate; wherein the upper clamping ring, the lower clamping ring and the pin are all located inside the telescopic sleeve.

[0010] As an embodiment of the present invention, the telescopic sleeve is in the shape of an accordion tube, the upper end of which is fixedly connected to the upper connecting plate, and the lower end is fixedly connected to a connecting flange, and the connecting flange is fixedly connected to the lower connecting plate by bolts.

[0011] As an implementation mode of the present invention, a sealing ring is fixedly provided at the outer edge of the placement opening.

[0012] As an embodiment of the present invention, the placement opening is formed by opening a notch on the side wall of the dust collection tube, and the left and right ends of the placement opening are opened along the tangent direction of the inner wall of the dust collection tube, so that the left and right sides of the notch are parallel to each other.

[0017] The packing mechanism is cleverly designed in that the suspension rod is automatically in a vertical state under the action of gravity. After the packing mechanism is placed in the upper placement port, the packing mechanism first stays for a while under the action of the latch. After the suspension rod is stationary, the gravity ball will be aligned with the through hole above the limiting groove. At this time, multiple latches are pulled out at the same time. Under the action of gravity, the gravity ball is stuck in the limiting groove, playing a supporting role for the upper packing tube. In the process of taking out the packing mechanism from the lower placement port, as the packing mechanism is pulled out, the suspension rod above it will gradually tilt, and at this time the packing mechanism above will gradually slide down. As the lowest packing mechanism is completely pulled out of the placement port, the packing mechanism above it slides onto the support plate, replacing the position of the lowest packing mechanism. At the same time, the suspension rod is stored in the cavity reserved between the grid plate and the lower end of the packing tube, or directly restores the vertical state.

[0018] The baffle is an arc-shaped push-pull type, which is easy to open and close and has good sealing performance. By setting a telescopic sleeve, the placement port and the insertion hole and the latch position can be secondary sealed to prevent tail gas leakage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention is clearly and completely described below in conjunction with specific embodiments.

[0036] like Figure 1-Figure 3 , Figure 5-10 A three-salt micron dust removal device is shown, which includes a dust removal cylinder 1 and a circulating water pool 3, a packing section, a spray section and a demisting section arranged in sequence from bottom to top in the dust removal cylinder 1. An air intake pipe 2 is arranged on the side wall of the dust removal cylinder 1 between the circulating water pool 3 and the packing section. The top of the dust removal cylinder 1 is connected to a chimney 9 through an exhaust pipe 8; The upper and lower side walls of the dust collecting cylinder 1 corresponding to the packing section are each provided with a square placement opening 10 with a width the same as the diameter of the inner wall of the dust collecting cylinder 1, and an L-shaped upper clamping ring 12 and an L-shaped lower clamping ring 13 are respectively provided on the side wall of the dust collecting cylinder 1 above and below the placement opening 10, and the upper clamping ring 12 and the lower clamping ring 13 are symmetrically arranged up and down, and an arc-shaped baffle 14 capable of completely covering the placement opening 10 is clamped between the two; An annular support plate 11 is provided at the inner wall of the dust collecting cylinder 1 flush with the bottom of the lower placement opening 10, and a plurality of packing mechanisms 4 are provided above the support plate 11, and the packing mechanism 4 includes a cylindrical packing cylinder 16 and a grid plate 17 provided at the lower part of the packing cylinder 16, a limit block 18 is fixedly provided at the middle part above the grid plate 17, and a limit groove 19 is provided at the top of the limit block 18, a bracket 20 is fixedly provided at the center of the bottom of the grid plate 17, and the bracket 20 is hinged to one end of the suspension rod 21 through a horizontally arranged rotating shaft, so that the suspension rod 21 can swing along a vertical plane; a spacing for accommodating the suspension rod 21 is reserved between the grid plate 17 and the lower end of the packing cylinder 16; a packing 23 is provided above the grid plate 17 in the packing cylinder 16, and a vertical through hole 30 corresponding to the limit groove 19 is reserved in the middle of the packing 23; The plurality of packing mechanisms are arranged at equal intervals in the upper and lower parts, and the free ends of the hanging rods 21 on the upper packing mechanism are pressed into the limiting grooves 19 of the lower packing mechanism.

[0037] The three-salt micron dust removal equipment provided by the present invention arranges the packing section in layers and arranges a multi-layer packing mechanism. When the tail gas emission does not meet the standard, the packing mechanism of the bottom layer is taken out, and the packing mechanism above slides down accordingly, and the packing mechanism after the packing is replaced is put back in from the top. It not only meets the treatment requirements of the tail gas, but also prolongs the service life of the packing, greatly reduces the production cost, and improves the economic benefits of the enterprise.

[0038] Furthermore, a plurality of packing mechanisms may be provided, and after the bottom packing mechanism is taken out, a new packing mechanism may be directly placed in from the upper placement port 10, thereby saving the time for replacing the packing and improving the exhaust gas treatment efficiency.

[0039] like Figure 3As shown, a plurality of jacks are evenly arranged on the side wall of the dust collecting cylinder 1 below the upper placement opening 10, and a latch 15 is arranged in the jack; in this embodiment, the placement opening 10 is arranged in front of the dust collecting cylinder 1, and two jacks are arranged symmetrically on the left and right sides of the placement opening 10, and the axes of the two jacks coincide with each other and intersect with the axis of the dust collecting cylinder 1. A transparent visual door 24 that can be opened and closed is arranged between the two placement openings 10 on the dust collecting cylinder 1, and the visual door 24 is arranged at the rear side of the dust collecting cylinder 1. The visual door 24 can be opened, and the inside of the dust collecting cylinder 1 can be observed through the visual door 24. In the process of placing the filling mechanism through the upper placement opening 10, the filling mechanism can be placed manually by opening the visual door 24, so that the filling mechanism can be placed stably on the two latches 15 to prevent the filling mechanism from tilting and getting stuck at the placement opening 10. At the same time, during the working process, the working state in the dust collecting cylinder 1 can also be observed through the visual door 24.

[0040] The limiting groove 19 is a spherical groove, and a gravity ball 22 corresponding to the limiting groove 19 is fixed at the free end of the suspension rod 21. The packing mechanism is cleverly designed, and the suspension rod 21 is automatically in a vertical state under the action of gravity. After the packing mechanism is placed in the upper placement port 10, the packing mechanism first stays for a while under the action of the latch 15. After the suspension rod 21 is stationary, the gravity ball 22 will be aligned with the through hole 30 above the limiting groove 19. At this time, multiple latches 15 are pulled out at the same time. Under the action of gravity, the gravity ball 22 is stuck in the limiting groove 19, which plays a supporting role for the upper packing tube 16.

[0041] Specifically, the gravity ball 22 includes a lead ball in the middle and a corrosion-resistant layer wrapped around the outside of the lead ball. In the process of taking out the packing mechanism from the lower placement port 10, as the packing mechanism is pulled outward, the hanging rod 21 above it will gradually tilt, and the packing mechanism above will gradually slide down. As the bottom packing mechanism is completely pulled out of the placement port 10, the packing mechanism above it slides onto the support plate 11, replacing the previous position of the bottom packing mechanism. At the same time, the hanging rod 21 is stored in the cavity reserved between the grid plate 17 and the lower end of the packing tube 16, or directly restored to a vertical state. When the length of the hanging rod 21 is different, when the filling tube 16 is taken out, the hanging rod 21 at the bottom is in different positions. When the hanging rod 21 is short and cannot touch the support plate 11 when in a horizontal state, in a working state, the hanging rod 21 of the lowest filling mechanism is in a drooping state. As the filling mechanism is taken out from the placement opening 10, the hanging rod 21 is received from the rear side of the filling tube 16 into the cavity reserved between the grid plate 17 and the lower end of the filling tube 16 under the interference of the placement opening 10, and then taken out from the placement opening together with the filling tube 16. When the bottom stuffing mechanism is taken out from the placement port 10, the hanging rod 21 of the stuffing mechanism above it gradually becomes horizontal, and the free end of the hanging rod 21 will be located above the stuffing plate 11. When the bottom stuffing mechanism is completely taken out, the hanging rod 21 of the stuffing mechanism above it is stored in the cavity reserved between the front grid plate 17 of the stuffing tube 16 and the lower end of the stuffing tube 16. When the working state, the hanging rod 21 is in a horizontal storage state.

[0042] The baffle 14 is an arc-shaped push-pull type, which is easy to open and close and has good sealing performance. By fixing a sealing ring 25 on the outer edge of the placement opening 10, the sealing effect can be further improved.

[0043] As a further optimization, Fig.11 and Fig.12 As shown, the side wall of the dust collecting cylinder 1 is respectively fixed with an annular upper connecting plate 26 and a lower connecting plate 27 above and below the placement opening 10, and a telescopic sleeve 28 is connected between the upper connecting plate 26 and the lower connecting plate 27; wherein the upper clamping ring 12, the lower clamping ring 13 and the latch 15 are all located inside the telescopic sleeve 28. Specifically, the telescopic sleeve 28 is in the shape of an accordion tube, and its upper end is fixedly connected to the upper connecting plate 26, and the lower end is fixedly connected to a connecting flange 29, and the connecting flange 29 is fixedly connected to the lower connecting plate 27 by bolts. By setting the telescopic sleeve 28, the placement opening 10 and the positions of the jack and the latch 15 can be secondary sealed to prevent exhaust gas leakage.

[0044] like Figure 4As shown, the placement opening 10 is formed by opening a groove on the side wall of the dust collector 1, and the left and right ends of the placement opening 10 are opened along the tangent direction of the inner wall of the dust collector 1, so that the left and right sides of the groove are parallel to each other, so that the central angle corresponding to the placement opening 10 can be less than 180 degrees, and the central angle corresponding to the baffle 14 is greater than 180 degrees, so that the baffle 14 can achieve better shielding and sealing of the placement opening 10.

[0045] The side wall of the circulating water pool 3 is provided with a water pipeline; the spray section is provided with a grid-shaped distributed spray pipe 5 and a plurality of spray heads 6 installed below the spray pipe 5; the demisting section is provided with a demister 7.

[0046] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
