Description

Technical Field

[0001] The utility model relates to the technical field of elevated torches, in particular to an assembly structure of a self-unloading elevated torch. Background Art

[0002] The elevated flare is one of the important facilities for safely and effectively treating the emission of combustible gases in petroleum refining and chemical plants. The self-unloading elevated flare has the following characteristics: one tower can support multiple sets of flares at the same time; the inspection and maintenance of one set of flares does not affect the normal operation of other flares; all inspection and maintenance work can be completed on the ground; the disassembly and assembly process of the flare head and the flare barrel can be completed without a large crane; the initial investment is slightly larger, but the inspection and maintenance costs are low; the flare position can be reserved for the later expansion of the device. It is widely used in elevated flares. The connection between each section of the self-unloading elevated flare currently in use adopts a flange sealing type. For example, the elevated flare system disclosed in patent CN201688421U that can be maintained and expanded online uses flange connections between the barrels, and the cost of the flanges is increased at both ends of the upper and lower connections. At the same time, the installation and disassembly process requires manual disassembly of bolts and gaskets, which brings great costs to the installation and maintenance of the device. Utility Model Content

[0003] The utility model aims to provide an assembly structure of a self-unloading elevated torch to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembly structure of a self-unloading elevated flare, comprising a bottom section cylinder, a terminal section cylinder and several intermediate cylinders, the lower end of the bottom section cylinder is welded with a flange, the flange is fixed to the ground by bolts, the diameters of the bottom section cylinder, the intermediate cylinder and the terminal section cylinder are equal, the upper ends of the bottom section cylinder and the intermediate cylinder are welded with a socket sleeve larger than their diameters, the upper end of the bottom section cylinder and the intermediate cylinder, between two adjacent intermediate cylinders, and between the lower end of the terminal section cylinder and the intermediate cylinder are all connected end to end by a socket sleeve, a cylindrical rubber pad is inserted into the inner cavity of the socket sleeve, an annular groove is provided on the outer side of the upper end of the rubber pad, the annular groove is adapted to be clamped with the upper port of the socket sleeve, and the lower end of the intermediate cylinder or the lower end of the terminal section cylinder is inserted into the rubber pad to achieve interference expansion with the socket sleeve.

[0005] Preferably, an elbow for inputting air is welded on the side of the bottom section cylinder.

[0006] Preferably, brackets for connecting to rails are welded to the sides of the bottom cylinder section, the middle cylinder section and the end cylinder section.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows: each cylinder of the utility model adopts a socket-type installation method, which is convenient for docking assembly and disassembly, and the socket sleeve is installed with a lined rubber pad, which is used to fill the gap after insertion. During operation, due to the negative pressure in the cylinder, the rubber pad is urged to fit tightly to achieve a better sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0012] See also Figure 1-2 The utility model provides a technical solution: an assembly structure of a self-unloading elevated flare, including a bottom section cylinder 1, a terminal section cylinder 3 and a plurality of intermediate cylinders 2. A flange 5 is welded to the lower end of the bottom section cylinder 1, and the flange 5 is fixed to the ground by bolts. The diameters of the bottom section cylinder 1, the intermediate cylinder 2 and the terminal section cylinder 3 are equal, and an elbow 4 for inputting air is welded to the side of the bottom section cylinder 1. Brackets 6 for connecting to tracks are welded to the sides of the bottom section cylinder 1, the intermediate cylinder 2 and the terminal section cylinder 3. (In the prior art, the Chinese utility model patent with publication number CN200996605Y discloses a cylinder, track and tower installation and connection scheme)

[0013] The upper ends of the bottom section cylinder 1 and the intermediate cylinder 2 are welded with a socket sleeve 7 that is larger than their diameters. The upper end of the bottom section cylinder 1 and the intermediate cylinder 2, between two adjacent intermediate cylinders 2, and between the lower end of the end section cylinder 3 and the intermediate cylinder 2 are all connected end to end through the socket sleeve 7. A cylindrical rubber pad 8 is inserted into the inner cavity of the socket sleeve 7. The outer side of the upper end of the rubber pad 8 is provided with an annular groove, which is adapted to be connected with the upper end of the socket sleeve 7.

[0014] The rubber pad 8 is made of fluorine-containing rubber to achieve good heat resistance and corrosion resistance while having good elasticity. The lower end of the intermediate cylinder 2 or the lower end of the final cylinder 3 is inserted into the rubber pad 8 to achieve interference expansion with the socket sleeve 7. Under the pressure of the deadweight of each cylinder, the downward socket-fit installation can be achieved, thereby facilitating docking assembly and disassembly. The upper end of the final cylinder 3 is installed with a torch head. When burning waste gas, the lower cylinder (including the bottom cylinder 1, the intermediate cylinder 2, and the final cylinder 3) will generate negative pressure, and the rubber pad 8 at the socket will shrink and press inward to achieve a good sealing effect.

[0015] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
