Description

Technical Field

[0001] The invention relates to the technical field of tobacco planting, in particular to a chimney glass fiber reinforced plastic inner tube fireproof structure based on a fuse mechanism. Background Art

[0002] In the existing industrial production field, chimneys are usually widely used as key channels for flue gas emissions. Taking fiberglass as an example, it is widely used in environmental protection equipment such as desulfurization and denitrification due to its high corrosion resistance and good mechanical properties.

[0003] In order to realize the flue gas desulfurization process in the chimney structure, an absorption tower is usually configured inside the chimney or in the connecting pipeline. In order to meet certain reaction conditions, the absorption tower often needs to be operated under conditions containing open flames.

[0004] The FRP material itself is easily affected by high-temperature flames and may cause combustion risks. Once a fire occurs inside a FRP chimney, since the absorption tower and the chimney are interconnected, a strong natural ventilation channel (i.e., chimney effect) may be formed. Once the open flame inside the absorption tower deviates from the design conditions or an abnormal situation occurs, the fire may quickly spread to the internal and external structures of the chimney pipe, causing a serious fire. Therefore, improvements need to be made to the above-mentioned problems to meet actual usage needs. Summary of the invention

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 4 The present invention provides a technical solution: a chimney glass fiber reinforced plastic inner tube fireproof structure based on a fuse mechanism, comprising a connecting square tube 1 and a purification component 2, the connecting square tube 1 is an integrated structure, the purification component 2 is arranged on the upper side of the connecting square tube 1, and the purification component 2 comprises a threaded fixing ring 201, a high temperature protective film 202, an internal threaded mounting ring 203, a smoke exhaust pipe 204, a HPEA filter 205, an activated carbon filter 206 and a molecular sieve 207, the threaded fixing ring 201 is arranged at the upper front end of the connecting square tube 1, and the inner upper end of the threaded fixing ring 201 is provided with a high temperature protective film 202, and ... The fixed ring 201 and the connecting square tube 1 are an integrated structure that is tightly connected. The outer side of the threaded fixing ring 201 is threadedly connected to an internally threaded mounting ring 203, and a smoke exhaust pipe 204 is installed on the upper side of the internally threaded mounting ring 203. An HPEA filter 205 is arranged at the lower end of the smoke exhaust pipe 204, an activated carbon filter 206 is installed above the HPEA filter 205, and a molecular sieve 207 is arranged on the upper side of the activated carbon filter 206. The HPEA filter 205, the activated carbon filter 206 and the molecular sieve 207 are arranged in the smoke exhaust pipe 204 from bottom to top, and the smoke exhaust pipe 204 is an integrated structure.

[0020] When using the chimney glass fiber reinforced plastic inner tube fire protection structure based on the fuse mechanism, Figure 2As shown, after the fire breaks out, a large amount of smoke flows into the inner side of the connecting square tube 1. The high-temperature protective film 202 has high-temperature resistance. When the heat is too high, the high-temperature protective film 202 will be damaged, causing the fire smoke to enter the smoke exhaust pipe 204. The HPEA filter 205 removes impurities such as particulate matter in the smoke. The activated carbon filter 206 can effectively filter out toxic gases such as carbon monoxide and carbon dioxide in the fire smoke. The molecular sieve 207 can further adsorb smoke dust in the fire smoke. After multi-stage filtration, the fire smoke is discharged through the smoke exhaust pipe 204.

[0021] At the same time, connecting frames 3 are installed on both sides of the connecting square tube 1, and two groups of connecting frames 3 are symmetrically arranged. The surface of the connecting frame 3 is threadedly connected with mounting bolts 4, and the surface of the mounting bolts 4 is threadedly connected with a reinforcing ring 5. The surface of the connecting square tube 1 is provided with a fireproof component 6 for isolating fire, and the fireproof component 6 includes a control mechanism 601, a reset handle 602, a temperature fuse 603, a movable shaft 604, a fire-blocking baffle 605, a fixing plate 606 and a fireproof sealing pad 607. The control mechanism 601 is arranged at the upper rear end of the connecting square tube 1, and the surface of the control mechanism 601 is provided with a reset handle 602, and the lower side of the control mechanism 601 is provided with a temperature Fuse 603, the lower end of the control mechanism 601 is rotatably connected to a movable shaft 604, and a fire-blocking baffle 605 is installed on the surface of the movable shaft 604, fixed plates 606 are installed on both sides of the inner rear end of the connecting square tube 1, and fireproof sealing pads 607 are provided on the surface of the fixed plate 606 and the surfaces of both ends of the fire-blocking baffle 605, the front end of the connecting square tube 1 is connected to a chimney inner tube 7, and a chimney outer tube 8 is provided on the outside of the chimney inner tube 7, the rear end of the connecting square tube 1 is connected to an inner tube connecting pipe 9, and an absorption tower 10 is installed at the rear end of the inner tube connecting pipe 9, an exhaust pipe 11 is installed on the top of the absorption tower 10, and a smoke exhaust fan 12 is installed at the rear end of the exhaust pipe 11.

[0022] The connecting square tube 1 is fixed to the chimney inner tube 7 and the inner tube connecting tube 9 by the threaded connection of the mounting bolts 4 and the surface of the connecting frame 3. The smoke generated in the chimney passes through the chimney inner tube 7 and the inner tube connecting tube 9 through the connecting square tube 1 and enters the absorption tower 10. After being purified by the absorption tower 10, the smoke is discharged by the exhaust fan 12. The mounting bolts 4 are prevented from loosening by the threaded connection of the reinforcing ring 5 and the mounting bolts 4. When a fire occurs, when the smoke temperature reaches the set threshold, the temperature melts. The breaking piece 603 will be melted, causing the control mechanism 601 to control the movable shaft 604 to rotate, so that the movable shaft 604 drives the fire barrier baffle 605 to rotate until the two ends of the fire barrier baffle 605 are in contact with the surface of the fixed plate 606, thereby preventing the fire and toxic high-temperature smoke from spreading through the pipeline. The fireproof sealing pad 607 can further improve the sealing performance of the connection between the fire barrier baffle 605 and the fixed plate 606, effectively blocking the smoke. This is the working principle of the chimney fiberglass inner tube fireproof structure based on the fuse mechanism.
