Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization towers, in particular to a connection structure of a glass fiber reinforced plastic desulfurization tower chimney. Background Art

[0002] The desulfurization tower is mainly used for desulfurization treatment of industrial waste gas. It is designed as a tower structure, including a cylindrical main part for desulfurization reaction. The main equipment of the main part is an absorption tower, a desulfurization pump, a booster fan, etc., and in order to be able to discharge the reaction waste gas that has been environmentally treated out of the absorption tower, it is necessary to install a chimney on the top of the cylindrical absorption tower. There are usually two ways to install the existing desulfurization tower chimney. One is to fix the chimney to the desulfurization tower body by welding. Although this connection method has good sealing and strong stability, it is more difficult to disassemble, which increases the maintenance of the chimney and the top of the desulfurization tower. The other method uses a flange to connect to the desulfurization tower body, which requires multiple bolts for fixing. Although it is convenient for disassembly, maintenance and replacement of the chimney, the flange connection is prone to corrosion after being exposed to wind and rain for a long time, affecting the connection strength of the chimney and the sealing performance of the desulfurization tower. In addition, due to the high height of the desulfurization tower, the above two methods both require the use of ropes to connect the chimney to the ground to improve its stability, but more ropes are used and the space occupied is larger. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a connection structure of a glass fiber reinforced plastic desulfurization tower chimney.

[0004] The technical solution of this utility model is as follows:

[0005] A connection structure for a glass fiber reinforced plastic desulfurization tower chimney, comprising a fixing pipe installed at the top of a desulfurization tower body, wherein the bottom end of the chimney can be inserted into the fixing pipe and the two are fixed by a flange assembly;

[0006] Two hoop-shaped sleeves are provided on the outside of the connection between the fixed pipe and the chimney, and one end of the two hoop-shaped sleeves is hinged, and the other end is detachably fixed to the outside of the flange assembly through a fixing piece and wraps it;

[0007] Reinforcement components are installed on the outside of the two hoop-shaped sleeves, and the reinforcement components are connected to the top of the desulfurization tower body.

[0008] In order to facilitate the insertion of the bottom end of the chimney into the fixed pipe and improve the stability and sealing of the chimney, the outer diameter of the bottom end of the chimney is not larger than the inner diameter of the fixed pipe. The chimney includes a main body section and a connecting section, and the connecting section is fixedly installed at the bottom of the main body section;

[0009] The inner diameter of the main body section is smaller than the inner diameter of the fixing tube, and the outer diameter of the connecting section is consistent with the inner diameter of the fixing tube.

[0010] In order to enhance the degree of tightness of the two hoop-shaped sleeves when wrapping the pipe, a fixing piece is also provided at one hinged end of the two hoop-shaped sleeves to fix the two together.

[0011] In order to enable the hoop-shaped sleeve to accommodate the flange assembly, an accommodating groove is opened along the inner wall of the two hoop-shaped sleeves, and the cross section of the accommodating groove is semicircular and can accommodate the flange plate of the flange assembly.

[0012] In order to improve the stability of the hoop sleeve when in contact with the pipeline and to increase the friction between the hoop sleeve and the pipeline, a plurality of anti-slip grooves are provided on the opposite sides of the two hoop sleeves and located above and below the accommodating groove.

[0013] In order to reduce the opening volume of the accommodating groove and ensure that the flange assembly can be accommodated, the longitudinal section of the accommodating groove is an isosceles trapezoidal shape, and the two bottom sides of the trapezoid are parallel to the length direction of the chimney.

[0014] The reinforcement component is specifically designed as follows: the reinforcement component includes a first mounting ring installed on the outside of the hoop sleeve and a second mounting ring installed on the top of the desulfurization tower body, and the first mounting ring and the second mounting ring are connected by a tensioned rope.

[0015] In order to facilitate the rope to fix the hoop at different angles and improve its stability in the horizontal and vertical directions, multiple second mounting rings are arranged from top to bottom along the top of the desulfurization tower body and are connected to the first mounting ring through multiple ropes.

[0016] In order to ensure that the design of the second mounting ring can play a role in enhancing stability and prevent the rope from tilting inward due to being too close to the axis of the fixed pipe, multiple second mounting rings are arranged horizontally away from the axis of the fixed pipe relative to the first mounting ring.

[0017] The beneficial effects of the present invention are as follows: the present invention is a connection structure of a glass fiber reinforced plastic desulfurization tower chimney. First, the chimney can be installed on the top of the desulfurization tower body, realizing the exhaust function of the desulfurization tower; secondly, the chimney is connected to the desulfurization tower body through a flange assembly, which facilitates the disassembly of the chimney, and then facilitates the inspection or replacement of the chimney; finally, the connection structure designed in this scheme can wrap the connection between the chimney and the fixed pipe through a hoop-shaped sleeve, and the flange assembly can be accommodated through the design of the accommodating groove, which can protect the connection and the flange assembly, and can effectively reduce the invasion of wind and rain on the connection and the flange assembly, and the hoop-shaped sleeve can support the connection, thereby improving the connection strength of the connection, and by designing a reinforcement assembly on the outside of the hoop-shaped sleeve, it can be connected to the top of the desulfurization tower through multiple ropes, replacing the traditional chimney fixed to the ground, saving the amount of rope and the overall space, and effectively strengthening the fixing strength of the chimney.

[0027] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0028] Example

[0029] As mentioned in the background technology, the desulfurization tower requires a chimney 3 to discharge the generated exhaust gas, and the existing desulfurization tower chimney 3 fixing form has many defects. Although the strength and sealing are good when fixed by welding, replacement and maintenance are relatively difficult. When connected by flange, the connection is exposed to wind and rain for a long time, which will shorten the service life and affect the fixing strength and sealing. Therefore, the inventor has improved and innovated the existing chimney 3 fixing form and designed a new connection structure, which is explained in detail below with reference to the drawings.

[0030] This embodiment provides a connection structure for the chimney of a glass fiber reinforced plastic desulfurization tower. Figure 1, including a fixed pipe 2 installed on the top of the desulfurization tower body 1. The fixed pipe 2 is generally integrally formed with the desulfurization tower body 1 or fixed by welding or other methods. It is mainly used to install the chimney 3. One of the main design points of this solution is that the bottom end of the chimney 3 can be inserted into the fixed pipe 2, so that the fixed pipe 2 can wrap the bottom end of the chimney 3, thereby improving the sealing performance of the chimney 3. Other seals between the chimney 3 and the fixed pipe 2 can use the methods in the existing technology and will not be elaborated on.

[0031] The outer diameter of the bottom end of the chimney 3 is not greater than the inner diameter of the fixed pipe 2. Figure 2 and Figure 3 , so that the bottom end of the chimney 3 can enter the upper end of the fixed pipe 2. Specifically, the chimney 3 includes a main body section 31 and a connecting section 32, and the connecting section 32 is fixedly installed at the bottom of the main body section 31. The two can be integrally formed, and in order to ensure the overall aesthetics of the chimney 3 and the fixed pipe 2, the outer diameter of the chimney 3 is consistent with the outer diameter of the main body section 31. However, the inner diameter of the main body section 31 is smaller than the inner diameter of the fixed pipe 2, which facilitates the fixed setting of the connecting section 32. The outer diameter of the connecting section 32 is consistent with the inner diameter of the fixed pipe 2, so that the connecting section 32 can be just inserted into the fixed pipe 2 to avoid a gap between the two, which affects the sealing performance. In addition, other seals between the connecting section 32 and the fixed pipe 2 adopt the form in the technology.

[0032] On the basis of the above structure, the fixed pipe 2 and the chimney 3 are fixed by a flange assembly 4. The flange assembly 4 includes two flange plates, which are respectively installed on the lower edge of the main section 31 of the chimney 3 and the upper edge of the fixed pipe 2. After the connecting section 32 is inserted into the fixed pipe 2, the two flange plates abut against each other and are fixed at the edges of the two flange plates by multiple bolt and nut assemblies.

[0033] Another major design point of this solution is to combine Figure 3 Two hoop-shaped sleeves 5 are provided on the outside of the connection between the fixed pipe 2 and the chimney 3, and one end of the two hoop-shaped sleeves 5 is hinged. The hinge method can be in the form of a hinge. The two hoop-shaped sleeves 5 can be combined into a cylindrical shape through the hinge, which can wrap the chimney 3 and the fixed pipe 2. The height of the hoop-shaped sleeve 5, that is, the length along the length direction of the chimney 3, should ensure that the connecting section 32 of the chimney 3 and the main section 31 symmetrical with respect to the flange are wrapped. The other ends of the two hoop-shaped sleeves are detachably fixed to the outside of the flange assembly 4 by fixing members 6 and wrap it. The fixing members 6 can be fixed in the form of bolts and nuts, and a fixing member 6 is also provided at one end where the two hoop-shaped sleeves 5 are hinged to fix the two, located above and below the hinged position, which can improve the fixing strength of the two hoop-shaped sleeves 5.

[0034] The flange assembly 4 is conveniently accommodated and protected by a receiving groove 8 along the inner wall of the two hoop-shaped sleeves 5. The receiving groove 8 is annularly opened from the hinged end of the hoop-shaped sleeve 5 to the fixed end, and the cross-section of the receiving groove 8 is semicircular, which can accommodate the flange of the flange assembly 4. When the hoop-shaped sleeve 5 is buckled at the connection between the chimney 3 and the fixed pipe 2, the flange of the connecting assembly is just in the receiving groove 8, and the longitudinal section of the receiving groove 8 is an isosceles trapezoid, and the two bottom sides of the trapezoid are parallel to the length direction of the chimney 3, and the bottom side position contacting the edge of the flange can be set to an arc-shaped concave form for adapting to the annular flange, so that the two waistlines of the trapezoid are above and below the flange, in order to accommodate the bolt and nut combination for fixing the flange, and the opening volume of the receiving groove 8 can be compressed to the maximum extent according to the flange assembly 4, thereby increasing the contact area between the hoop-shaped sleeve 5 and the fixed pipe 2 and the chimney 3, thereby improving stability.

[0035] On the basis of the above structure, a plurality of anti-slip grooves 9 are provided on the opposite sides of the two hoop-shaped sleeves 5 and located above and below the accommodating groove 8. By providing the protective grooves, the friction between the inner wall of the hoop-shaped sleeve 5 and the outer wall of the chimney 3 and the fixed pipe 2 can be increased, thereby preventing the hoop-shaped sleeve 5 from drastically deviating.

[0036] In this embodiment, as one of the other main design points of this solution, the outer sides of the two hoop-shaped sleeves 5 are both equipped with reinforcement components 7, combined with the Figure 4 and Figure 5 , and the reinforcement component 7 is connected to the top of the desulfurization tower body 1, which can replace the existing chimney 3 connected to the bottom surface through a longer steel wire rope, which can save the rope 73 and save the occupied space. Specifically, the reinforcement component 7 includes a first mounting ring 71 installed on the outside of the hoop sleeve 5 and a second mounting ring 72 installed on the top of the desulfurization tower body 1, and the first mounting ring 71 and the second mounting ring 72 are connected by a tensioned rope 73. Through the connection of the rope 73, the hoop sleeve 5 can be fixed to the top of the desulfurization tower body 1, and then the fixing strength of the chimney 3 can be strengthened.

[0037] In addition, there are multiple second mounting rings 72 arranged from top to bottom along the top of the desulfurization tower body 1, and connected to the first mounting ring 71 through multiple ropes 73, so that the multiple ropes 73 can be at different inclination angles, thereby improving the stability of the chimney 3 in the horizontal and vertical directions. Moreover, the multiple second mounting rings 72 are arranged in the horizontal direction away from the axis of the fixed pipe 2 relative to the first mounting ring 71. Since the top of the desulfurization tower body 1 is inclined, that is, the second mounting ring 72 at the top is located outside the first mounting ring 71, it is ensured that the multiple ropes 73 are in an outward inclined state after being connected, avoiding them from tilting inward and losing the effect of strengthening the stability of the chimney 3. In addition, multiple first mounting rings 71 can be installed circumferentially around the outer side of the hoop sleeve 5, and correspondingly, multiple second mounting rings 72 are installed on the top of the desulfurization tower body 1 below each first mounting ring 71, so that it can be connected to the top of the desulfurization tower body 1 along the circumference of the hoop sleeve 5, thereby improving the stability of the chimney 3 at multiple positions.
