Description

Technical Field

[0001] The invention relates to the technical field of industrial chimney manufacturing, in particular to a steel-assembled super-high chimney. Background Art

[0002] Industrial chimneys are tall structures with a high center of gravity and a very high slenderness ratio. Such structures are extremely sensitive to earthquakes or strong winds. The effects of earthquakes and strong winds on chimneys are mainly lateral effects on chimney structures, causing chimney swaying. The swaying amplitude of chimneys is related not only to the intensity of earthquakes and winds, but also to the chimney's own natural vibration frequency. Therefore, changing the natural frequency of the chimney structure can effectively reduce the impact of earthquakes and strong winds on the stability of chimneys. At the same time, for steel-assembled chimneys, it is necessary to set up an anti-corrosion and heat-insulating layer inside the steel chimney. Due to the flexibility of the steel structure, the vibration of the chimney body will have an adverse effect on the internal anti-corrosion and heat-insulating structure, causing the anti-corrosion and heat-insulating layer to crack and age, and reduce performance. The maintenance of the anti-corrosion and heat-insulating layer is not only costly, but also requires shutdowns for inspections, thus affecting normal production. Summary of the invention

[0045] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0046] Steel-assembled super-high chimneys need to be provided with an anti-corrosion and heat-insulating layer inside. The anti-corrosion and heat-insulating layer used in the prior art has poor use effect, and after each process is completed during the construction process, it needs to be dried and then polished, and there is a problem of long inter-process interval time. At the same time, the existing chimney anti-vibration device has poor vibration suppression caused by earthquakes and strong winds, and the structure is relatively complex and occupies a large area. The technical scheme adopted by the present invention, through the anti-corrosion and heat-insulating layer composed of a closed primer layer, an elastic anti-corrosion bonding layer, a lightweight vitrified ceramic tile layer and an anti-corrosion and anti-seepage surface layer, not only has the advantages of convenient construction, short inter-layer construction interval time, fast construction, strong temperature resistance, strong acid and alkali corrosion resistance, strong anti-corrosion bonding force, low repair rate, strong adaptability, etc., its elastic material can also effectively damp the vibration of the chimney body, and at the same time, it can also avoid the cracking and aging of the anti-corrosion and heat-insulating layer due to the vibration of the chimney; the stabilizing device that realizes the stability of the chimney body by horizontal rotation relative to the chimney body can further reduce the vibration amplitude of the chimney.

[0047] The specific implementation of the technical solution of the present invention includes the following contents: Example 1

[0048] Reference Figure 1 The steel-assembled super-high chimney of this embodiment includes a chimney body and a stabilizing device 2. The chimney body is composed of a plurality of cylindrical steel cylinders 1 connected in series. The chimney body is fixedly connected in series by flanges 4 at both ends of the cylindrical steel cylinders 1. The flanges 4 are fixed by bolts. The chimney body is installed on a foundation 3. The inner wall of the cylindrical steel cylinder 1 is covered with an anti-corrosion and heat-insulating layer. Figure 4 The anti-corrosion and heat-insulating layer includes a closed primer layer 51, an elastic anti-corrosion bonding layer 52, a lightweight vitrified ceramic tile layer 53 and an anti-corrosion and anti-seepage surface layer 54; the closed primer layer 51 is evenly applied on the inner wall of the cylindrical steel cylinder 1, the lightweight vitrified ceramic tile layer 53 is adhered to the inner side of the closed primer layer 51 through the elastic anti-corrosion bonding layer 52, and the anti-corrosion and anti-seepage surface layer 54 is scraped on the inner side of the lightweight vitrified ceramic tile layer 53.

[0049] Specifically in the construction, the closed primer layer 51 is configured by mixing and stirring a closed primer and a closed primer curing agent, the mixing mass ratio of the closed primer and the closed primer curing agent is 10:1, and the coating thickness of the closed primer layer 51 is 30±10μm; the elastic anti-corrosion bonding layer 52 and the anti-corrosion and anti-seepage surface layer 54 are configured by mixing and stirring an elastomeric anti-corrosion material paint and an elastomeric anti-corrosion material curing agent, the mixing mass ratio of the elastomeric anti-corrosion material paint and the elastomeric anti-corrosion material curing agent is 14:1, and ... elastomer anti-corrosion material curing agent, the mixing mass ratio of the elastomeric anti-corrosion material paint and the elastomer anti-corrosion material curing agent is 14:1, and the elastic anti-corrosion bonding layer 52 and the anti-corrosion and anti-seepage surface layer 54 are configured by mixing and stirring an elastomeric anti-corrosion material paint and an elastomer anti-corrosion material curing agent, the mixing mass ratio of the elastomeric anti-corrosion material paint and the elastomer anti-corrosion material curing agent is 14:1, and the elastic anti-corrosion bonding layer 52 and the anti-corro The thickness of layer 52 is 3±0.5mm, and the thickness of the anti-corrosion and anti-seepage surface layer 5.4 is 2±0.5mm; the lightweight vitrified ceramic tile layer 53 adopts 230ⅹ120ⅹ50mm lightweight vitrified ceramic tiles, which are pasted by kneading method, and the width of brick joints is less than 3mm; the transverse joints are horizontal, and the longitudinal joints are staggered, and the staggered width is 1 / 3-1 / 2 of the width of the brick body. The lightweight vitrified ceramic tiles are pasted from bottom to top, and the height of continuous pasting shall not exceed ten layers, and shall be adapted to the degree of curing of the elastomeric anti-corrosion material to prevent the lower brick body from being displaced or moved.

[0050] The present embodiment uses elastomeric anti-corrosion material paint as the main material of the elastic anti-corrosion bonding layer 52 and the anti-corrosion and anti-seepage surface layer 54. Since the elastic anti-corrosion bonding layer 52 and the anti-corrosion and anti-seepage surface layer 54 themselves have a certain elasticity and they are passively swaying, and their deformation has a certain hysteresis, when they sway with the chimney body, the elastic anti-corrosion bonding layer 52 and the anti-corrosion and anti-seepage surface layer 54 will absorb the energy of the swaying and play a certain damping role, thereby reducing the swaying amplitude of the chimney body.

[0051] The traditional construction method of the anti-corrosion and heat insulation layer is to lay the anti-corrosion and heat insulation layer after the chimney body is built. This results in most of the laying operations being high-altitude operations, which is not only highly dangerous, but also can only open one working surface at the same time, and gradually unfold from bottom to top, which results in extremely low laying efficiency. Generally speaking, the laying time of the anti-corrosion and heat insulation layer needs to occupy more than 80% of the entire construction time. In order to improve the efficiency of the work, during the specific construction of this embodiment, before the cylindrical steel cylinder 1 is fixedly connected in series, the construction personnel lay the anti-corrosion and heat insulation layer on the ground, and cover the inner wall of the cylindrical steel cylinder 1 with the anti-corrosion and heat insulation layer; after the cylindrical steel cylinder 1 is fixedly connected in series, that is, after the chimney body is erected, considering that the joints at the cylinder connection need to strengthen the anti-corrosion and heat insulation measures, the anti-corrosion and anti-seepage surface layer 54 is scraped on the inner wall of the cylindrical steel cylinder 1 where it is fixedly connected in series, and the newly scraped anti-corrosion and anti-seepage surface layer 54 is smoothly connected to the surface of the anti-corrosion and anti-seepage surface layer 54 scraped before the cylindrical steel cylinder 1 is fixedly connected in series. Since the workload of laying the anti-corrosion and anti-seepage surface layer 54 of the gap is relatively small, most of the work on the anti-corrosion and heat-insulating layer is carried out on the ground, and each section of the cylindrical steel cylinder 1 can be constructed separately, which not only saves time but also ensures the consistency of the construction environment of each section of the cylindrical steel cylinder 1, thereby ensuring the consistency of the performance of the entire anti-corrosion and heat-insulating layer.

[0052] The stabilizing device 2 is installed on the upper part of the chimney body, and the chimney body is stabilized by horizontal rotation relative to the chimney body. The rotation axis of the stabilizing device 2 coincides with the axis of the chimney body. As described in the background technology, an industrial chimney is a tall structure with a high center of gravity and a very large slenderness ratio. This structure is extremely sensitive to earthquakes or strong winds. The effects of earthquakes and strong winds on chimneys are mainly the lateral effects on the chimney structure, which causes the chimney to sway. The chimney vibration-resistant stabilizing structure in the prior art generally adopts the form of guy wires, tower supports or windbreakers. Guy wires and tower supports have relatively large requirements for the site. Since the vibration amplitude of the chimney is the largest at the top, the guy wires cannot protect the top and are prone to form a stress concentration point. The cost of tower erection is too high for super-high chimneys. Since the tower itself is also an elastic structure, the higher the chimney is, the lower the vibration reduction effect of the tower itself is. Therefore, the two can only be used as auxiliary vibration reduction measures. For the windbreaker, it belongs to passive vibration reduction and has only a certain effect on strong winds.

[0053] The stabilizing device 2 of this embodiment realizes the stability of the chimney body by horizontal rotation relative to the chimney body, which belongs to an active vibration prevention. Specifically, in this embodiment, the stabilizing device 2 includes: a fixed structure 21, a rotating structure 22, a counterweight structure 23 and a driving structure 24; the fixed structure 21 is used to fix the stabilizing device 2 on the upper part of the chimney body; the driving structure 24 is used to drive the stabilizing device 2 to rotate; the counterweight structure 23 is used to increase the angular momentum of the stabilizing device 2; the rotating structure 22 is used to rotatably connect the counterweight structure 23 and the fixed structure 21, which can be realized by a bearing structure. The stabilizing device 2 is installed around or on the upper part of a cylindrical steel cylinder 1 at the top of the chimney body. The stabilizing device 2 is installed on the upper part of the chimney body, and through horizontal rotation relative to the chimney body, the gyroscopic effect generated by the rotation of the counterweight structure 23 is used to generate a centripetal force. The greater the swing of the chimney body, the more it deviates from the axis, and the greater the centripetal force, the greater the damping of the chimney, thereby achieving the stability of the chimney body. At the same time, the heavier counterweight structure 23 will also change the mass distribution of the chimney body, thereby improving the stability of the chimney top.

[0054] As an implementation method of this embodiment, refer to the attached Figure 2 , the driving structure 24 is a vertical axis wind blade. Driven by wind, the vertical axis blade can have many forms. Its main feature is that the blades at different positions have different windward surfaces for the same wind direction, which leads to the difference in torque and realizes the rotation of the blade; the counterweight structure 23 of this embodiment is a thick-walled cast iron cylinder; the vertical axis wind blade is fixedly mounted on the outer wall of the counterweight structure 23; the inner wall of the counterweight structure 23 is connected to the fixed structure 21 through the rotating structure 22. In this embodiment, the greater the wind force, the faster the counterweight structure 23 rotates, and the greater the centripetal force generated. Therefore, this technical solution is an adaptive anti-vibration structure, and does not require additional energy input. It not only achieves better anti-vibration, but also has certain economy.

[0055] As a preferred embodiment, there are multiple stabilizing devices 2, which are respectively installed on cylindrical steel cylinders 1 with different heights, and the mass ratio of the counterweight structure of at least two stabilizing devices 2 is 1:6. The reason why the mass ratio of the counterweight structure in this embodiment is set to 1:6 is that the vibration of the chimney not only has first-order vibration, but also second-order and third-order vibrations. Different vibrations have a certain correlation, which is related to the structural shape of the chimney itself. The third-order vibration is relatively small and can be ignored. The frequency of the second-order vibration is about 6 times that of the first-order vibration. Therefore, the first-order vibration and the second-order vibration are mainly eliminated. The use of a stabilizing device with a corresponding mass ratio can effectively offset the chimney vibrations of the above-mentioned different frequencies. Example 2

[0056] As a preferred embodiment, refer to the attached Figure 3 On the basis of Example 1, the vertical length of the vertical wind blade is greater than the height of the thick-walled cast iron cylinder 1, and the distance between the vertical wind blade and the outer wall of the chimney body is greater than 10 cm and less than 20 cm. The vertical length of the vertical wind blade is greater than the height of the thick-walled cast iron cylinder 1, and the vortex formed by the strong wind on the back of the chimney body can be destroyed by the rotation of the blade. However, if the distance between the vertical wind blade and the outer wall of the chimney body is too large, the effect of destroying the vortex is poor. If the distance is too small, it will cause the blade to scrape against the chimney body. Through experiments, 10-20 cm is preferred. Example 3

[0057] As another embodiment, refer to the attached Figure 5 The driving structure of this embodiment is an electromagnetic driving structure, which is driven by electromagnetic force, similar to the outer rotor motor structure; the counterweight structure 23 is a thick-walled cast iron cylinder; the outer wall of the electromagnetic driving structure is fixedly connected to the inner wall of the counterweight structure 23; the electromagnetic driving structure is connected to the fixed structure 21 through a rotating structure. The electromagnetic driving structure includes a rotor 25 and a stator 26. The stator 26 is an electromagnetic coil, and its power supply comes from the power supply on the ground. The rotor 25 is a permanent magnet or magnetic steel, which is fixedly connected to the counterweight structure 23, so that the counterweight structure rotates with the rotor 25. The stator 26 is fixed on the fixed structure 21. The fixed structure 21 has a certain thermal insulation performance, such as ceramic washers can be used to achieve thermal insulation with the chimney body. The electromagnetic force generated by the stator coil drives the rotor 25 to rotate, and the rotor 25 then drives the counterweight structure 23 to rotate. Based on the fixed axis of the gyro effect of the same principle as in Example 1, the active vibration prevention of the chimney is realized.

[0058] Since the electromagnetic drive structure can achieve speed control, in a specific application, by adjusting the input current, the rotation frequency of the electromagnetic drive structure is made greater than the natural frequency of the chimney body, so that the chimney body cannot vibrate, thereby achieving more efficient vibration reduction.

[0059] According to the empirical formula, the natural frequency of the chimney body is: ;in EI is the stiffness of the chimney body, is the mass per unit height of the chimney body, is the height of the chimney body.

[0060] The technical solution of the embodiment of the present invention was applied in a chimney renovation project of a heat source plant in Taiyuan centralized heating. After testing and comparison with traditional processes, the technical effects of quick construction, firm structure, strong stability, durability, low repair rate, energy saving and environmental protection, and low subsequent maintenance costs were achieved.

[0061] Those skilled in the art will appreciate that although some embodiments herein include certain features included in other embodiments but not other features, the combination of features from different embodiments is meant to be within the scope of the present invention and to form different embodiments.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
