Description

Technical Field

[0001] This utility model relates to the field of activated carbon towers, specifically to an activated carbon tower with a fire sprinkler structure. Background Technology

[0002] In the field of organic waste gas purification, activated carbon towers are widely used due to their advantages such as high adsorption efficiency and simple operation, and can effectively treat various organic waste gases such as alkanes and alcohols. However, existing conventional activated carbon towers mostly focus on adsorption and filtration functions, and often lack targeted safety protection designs.

[0003] For flammable and explosive organic waste gases such as alcohol and alkanes, the activated carbon adsorption process can easily cause the temperature inside the tower to rise due to the exothermic reaction. If not intervened in time, this may lead to a fire or even an explosion. Furthermore, some existing equipment lacks effective temperature monitoring, emergency cooling, and explosion venting protection structures, making it difficult to address the aforementioned safety hazards and even seriously affecting the safety and stability of equipment operation, thus failing to meet the special safety requirements of flammable and explosive waste gas treatment scenarios. Utility Model Content

[0004] The problem to be solved by this utility model is to provide an activated carbon tower with a fire sprinkler structure.

[0005] To solve the above problems, this utility model provides an activated carbon tower with a fire sprinkler structure. To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problems is as follows: An activated carbon tower with a fire sprinkler structure includes: a housing with an air inlet and an air outlet, the housing containing packing material capable of filtering gas; a sprinkler pipe including a sprinkler branch pipe and a sprinkler main pipe disposed on the top of the housing, and a vertical pipe disposed on the outside of the side of the housing; nozzles, each sprinkler branch pipe having a plurality of nozzles arranged at intervals, the output end of the nozzles being located inside the housing; a thermometer disposed on the inner wall of the housing; and a burst relief diaphragm disposed on the side wall of the housing; wherein, the top of the vertical pipe is vertically connected to the sprinkler main pipe, the bottom of the vertical pipe is a water inlet, the sprinkler branch pipes are vertically connected to the sprinkler main pipe, and the plurality of sprinkler branch pipes are arranged parallel to each other.

[0006] As a further improvement of this utility model, the bottom of the box is provided with several drainage holes.

[0007] As a further improvement of this utility model, the bottom of the box is fixed with vertical support legs.

[0008] As a further improvement of this utility model, the top of the box is provided with a detachable inspection window, the number of which is the same as the number of nozzles, and the inspection windows and nozzles are arranged alternately at intervals on the top of the box.

[0009] As a further improvement of this utility model, a bypass pipe is connected in parallel to the vertical pipe, the bypass pipe is equipped with a solenoid valve, and the vertical pipe is equipped with a first manual valve, which is located between two intersections of the bypass pipe and the vertical pipe.

[0010] As a further improvement of this utility model, the bypass pipe is equipped with a second manual valve and a third manual valve, which are respectively mounted on both sides of the solenoid valve.

[0011] As a further improvement of this utility model, a fourth manual valve is installed at the end of each spray branch pipe near the main spray pipe.

[0012] As a further improvement of this utility model, the area of ​​the explosion relief disc is larger than the area of ​​a single inspection window.

[0013] As a further improvement of this utility model, the inner diameter of the main spray pipe and the vertical pipe are equal, the inner diameter of the main spray pipe is larger than the inner diameter of the branch spray pipe, and the main spray pipe, the branch spray pipe, and the vertical pipe are galvanized pipes.

[0014] As a further improvement of this utility model, the housing is made of SS41 or SUS304 material.

[0015] The beneficial technical effects of the activated carbon tower with fire sprinkler structure described in this application are: By installing a thermometer on the inner wall of the chamber, the temperature inside the tower during the activated carbon adsorption process can be monitored in real time. Combined with the spray structure at the top of the chamber, which consists of a main spray pipe, parallel spray branches, and nozzles, water can be introduced in time through the vertical pipe inlet when the temperature rises abnormally. The water is then sprayed onto the packing area inside the chamber through the nozzles to cool it down, effectively preventing fire hazards caused by the exothermic reaction during the adsorption of flammable and explosive organic waste gases.

[0016] The explosion relief vents installed on the side walls of the enclosure can quickly release pressure when the pressure inside the tower accidentally reaches a critical value, preventing explosions or reducing the explosive force, thus reducing the risk of equipment damage and environmental impact, and making up for the lack of explosion relief protection in conventional activated carbon towers.

[0017] The spray pipes adopt a layout where vertical pipes are connected perpendicularly to the main spray pipe and the branch pipes are parallel and perpendicular to the main pipe. Combined with the spacing of the nozzles on the branch pipes, this ensures that the spray range evenly covers the packing material inside the box. At the same time, the vertical pipes are located on the outside of the side of the box, so as not to affect the gas flow and adsorption efficiency inside the box, thus achieving a reasonable balance between fire protection function and exhaust gas purification function.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to specific embodiments: To achieve the purpose of this utility model, please refer to Figures 1 to 6 An activated carbon tower with a fire sprinkler structure includes: a housing with an air inlet 16 and an air outlet 17, and packing material for filtering gases inside the housing; a sprinkler system including a sprinkler branch pipe 2 located above the top of the housing, a sprinkler main pipe 3, and a vertical pipe 9 located on the outside of the side of the housing; nozzles 1, with a plurality of nozzles 1 arranged at intervals on each sprinkler branch pipe 2, the output end of the nozzles 1 located inside the housing; a thermometer 6, installed on the inner wall of the housing; and explosion relief diaphragms 5, installed on the side wall of the housing. The top of the vertical pipe 9 is vertically connected to the sprinkler main pipe 3, the bottom of the vertical pipe 9 is a water inlet 8, the sprinkler branch pipes 2 are vertically connected to the sprinkler main pipe 3, and the plurality of sprinkler branch pipes 2 are arranged parallel to each other.

[0022] Figure 1 The arrows in the diagram indicate the direction of gas flow.

[0023] The beneficial effects of adopting the above technical solution are as follows: a thermometer 6 is installed on the inner wall of the chamber to monitor the temperature change of the activated carbon adsorption process in real time. In conjunction with the top spray system consisting of the main spray pipe 3, the branch spray pipe 2 and the nozzle 1, water can be drawn through the water inlet 8 of the vertical pipe 9 to spray water when the temperature is abnormal, so as to achieve rapid cooling and effectively prevent the risk of fire caused by the exothermic reaction. At the same time, the explosion relief plate 5 installed on the side wall of the chamber can quickly release pressure when the internal pressure exceeds the limit, reducing the explosion hazard. Thus, while ensuring the exhaust gas purification function, the safety and reliability of the equipment in flammable and explosive exhaust gas environments are significantly improved.

[0024] In some other embodiments of this utility model, a plurality of drainage holes 7 are provided at the bottom of the box.

[0025] The beneficial effects of adopting the above technical solution are: the drainage hole 7 can drain the water accumulated in the box in time after the spray system is started or after routine maintenance, so as to avoid water retention affecting the performance of the packing or causing corrosion of the box. At the same time, it is also conducive to keeping the airflow channel inside the tower dry and unobstructed, ensuring the stable operation of the waste gas treatment process.

[0026] In some other embodiments of this utility model, the bottom of the box is fixed with vertical support legs 18.

[0027] The beneficial effects of adopting the above technical solution are: the support leg 18 can lift the tower body off the ground, which facilitates the drainage operation and daily inspection of the bottom drainage hole 7, while enhancing the ventilation and moisture-proof effect of the bottom of the box, extending the service life of the equipment, and facilitating on-site installation and pipeline layout.

[0028] In some other embodiments of this utility model, a detachable inspection window 15 is provided on the top of the box body. The number of inspection windows 15 is the same as the number of nozzles 1, and the inspection windows 15 and nozzles 1 are arranged alternately at intervals on the top of the box body.

[0029] The beneficial effects of adopting the above technical solution are: the inspection window 15 facilitates direct observation of the working status of the nozzle 1 and the condition of the packing inside the box, realizing a reasonable layout of the spray system and inspection function, which does not affect the spray coverage area and facilitates daily maintenance and troubleshooting.

[0030] like Figure 5 As shown, in some other embodiments of this utility model, a bypass pipe 10 is connected in parallel to the vertical pipe 9. The bypass pipe 10 is equipped with a solenoid valve 4, and the vertical pipe 9 is equipped with a first manual valve 11. The first manual valve 11 is located between two intersections of the bypass pipe 10 and the vertical pipe 9.

[0031] The beneficial effects of adopting the above technical solution are: forming a dual control path of automatic and manual operation; when the solenoid valve 4 fails or needs maintenance, the first manual valve 11 can be closed and the spraying function can be maintained by using the bypass pipe 10, thereby improving the reliability of system operation and the convenience of maintenance.

[0032] In some other embodiments of this utility model, the bypass pipe 10 is equipped with a second manual valve 12 and a third manual valve 13, which are respectively mounted on both sides of the solenoid valve 4.

[0033] The advantages of adopting the above technical solution are: it can isolate the solenoid valve 4 during maintenance, enabling maintenance without shutting down the system, and it also facilitates the individual testing or replacement of the solenoid valve 4, further ensuring the operational flexibility of the sprinkler control system.

[0034] In some other embodiments of this utility model, each spray branch pipe 2 is equipped with a fourth manual valve 14 at one end near the spray main pipe 3.

[0035] The beneficial effects of adopting the above technical solution are as follows: A fourth manual valve 14 is installed at the end of each spray branch pipe 2 near the main spray pipe 3, allowing independent opening and closing control of a single spray branch pipe 2, facilitating segmented maintenance, cleaning, or flow adjustment. This avoids the entire spray system from being shut down due to localized failures, improving system maintainability.

[0036] In some other embodiments of this invention, the area of ​​the explosion relief disc 5 is larger than the area of ​​a single inspection window 15.

[0037] The explosion relief disc 5 is a disposable overpressure protection device. Structurally, it consists of a diaphragm and a clamp. It is of the positive arch type, meaning the arched surface faces the medium side. When overpressure occurs, the top of the arch stretches and ruptures. The diaphragm thickness is controlled between 1mm and 2mm, and the edges of the explosion relief disc 5 are sealed to ensure zero leakage.

[0038] The beneficial effects of adopting the above technical solution are: ensuring that the explosion relief disc 5 has sufficient pressure relief area, which can quickly release internal pressure when overpressure occurs, effectively reducing the risk of damage to the tower structure caused by the explosion impact, and avoiding the impact of openings such as the inspection window 15 on the explosion relief efficiency.

[0039] In some other embodiments of this utility model, the inner diameters of the main spray pipe 3 and the vertical pipe 9 are equal, the inner diameter of the main spray pipe 3 is larger than the inner diameter of the branch spray pipe 2, and the main spray pipe 3, the branch spray pipe 2, and the vertical pipe 9 are galvanized pipes.

[0040] The advantages of adopting the above technical solution are: it facilitates the stable distribution of water flow in the main pipe before it enters each branch pipe, ensuring uniform spraying. All pipes are made of galvanized steel, enhancing corrosion resistance and making them suitable for humid and exhaust gas treatment environments, thus extending the service life of the pipeline.

[0041] In some other embodiments of this utility model, the housing is made of SS41 or SUS304 material.

[0042] SS41 is a common carbon structural steel according to the Japanese JIS G3101 standard, and SUS304 is an austenitic stainless steel according to the Japanese JIS G4303 standard.

[0043] The beneficial effects of adopting the above technical solution are: SUS304 stainless steel has excellent corrosion resistance and high temperature resistance, and materials can be flexibly selected according to the actual waste gas composition and environmental conditions to ensure the durability of the tower body in flammable, explosive and corrosive gases.

[0044] This application describes an activated carbon tower with a fire sprinkler system. For some organic waste gases, such as flammable and explosive gases like alcohol and alkanes, this type of activated carbon tower requires an additional fire sprinkler design. Fire nozzles and fire sprinkler pipelines are designed between the activated carbon layers. The tower body is also equipped with a thermometer 6, a burst vent 5, and bottom drainage. During operation, when the temperature inside the tower reaches 70℃, the sprinkler solenoid valve automatically opens to supply water for cooling and fire extinguishing. The burst vent 5 in the tower body helps to mitigate the explosive force and damage in the event of an explosion.

[0045] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
