Abstract
Description
Technical Field
[0001] This utility model relates to the field of boiler flue gas treatment technology, and in particular to an absorption tower with a safety fire-fighting device. Background Technology
[0002] Flue gas desulfurization is an important flue gas purification and treatment device at the tail end of a boiler. Through the absorption tower, SO2 and soot in the flue gas can be removed, pollutant emissions can be reduced, acid rain can be prevented, and the quality of the social atmospheric environment can be improved. The safe construction, operation and maintenance of the absorption tower has always been a key link in the boiler system.
[0003] Currently, the internal equipment of the absorption tower includes a spray layer, a demister, and an anti-corrosion layer, which serve to wash SO2 and dust in the flue gas. These devices are all made of organic materials, making them wear-resistant and corrosion-resistant. However, the spray layer, demister, and anti-corrosion layer inside the tower will quickly soften, deform, crack, or fall off under high temperatures above 100°C. The absorption tower is equipped with a slurry spray layer inside. The flue gas, which is around 130°C, is rapidly cooled to around 50°C under the action of the spray slurry, which protects the spray layer, demister, and anti-corrosion layer inside the absorption tower, allowing the absorption tower to operate normally and continuously. However, the main body of the absorption tower is a steel structure. During maintenance, welding and cutting may be used, generating sparks. The anti-corrosion layer is made of flammable materials, posing a fire risk. The anti-corrosion layer is made of glass flakes, which may generate flammable gases during construction. If these gases are not vented in time and accumulate to a certain concentration, they can also cause a fire under the influence of sparks. At the same time, the spray layer slurry is powered by a slurry circulation pump. If the circulation pump stops due to unexpected situations such as circuit failure, a large amount of high-temperature flue gas will quickly damage the spray layer, demister, and anti-corrosion layer inside the absorption tower. At present, there is only a spray system at the inlet of the absorption tower, which has a cooling effect on the high-temperature flue gas, but it has no effect on the fire prevention of flammable materials inside the tower. During the maintenance of the absorption tower, many temporary measures need to be set up, which is extremely inconvenient. In the past, there have been many cases of fires inside the absorption tower during the installation and maintenance of the anti-corrosion layer. Because the fire could not be extinguished quickly, it caused great danger to personnel and equipment.
[0004] Therefore, it is necessary to develop an absorption tower with a safety fire-fighting device to overcome the above-mentioned technical problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide an absorption tower with a safety fire-fighting device, which effectively overcomes the defects of the prior art.

[0013] Furthermore, the ends of the aforementioned horizontal and vertical pipes are connected to annular support rings, and L-shaped support members are spaced circumferentially on the inner wall of the top of the aforementioned absorption tower body, with the aforementioned support rings inserted into the aforementioned support members.
[0014] Furthermore, the aforementioned fire sprinkler system includes a ring-shaped main pipe, which is fixed to the inner wall of the top of the absorption tower body. Multiple third nozzles are spaced apart on the inner side of the main pipe. The main pipe is connected to a horizontal water inlet pipe that penetrates the side wall of the absorption tower body. The water inlet pipe is connected to a fire water pipe externally through a pipeline.
[0015] Furthermore, it also includes a control system, which includes a controller, a temperature measuring device, and an electrically controlled valve.

[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0027] Example: Figure 1 As shown, the absorption tower with safety fire protection device in this embodiment includes an absorption tower body 1, and a fire sprinkler device 2 is provided in the top of the absorption tower body 1. The fire sprinkler device 2 is connected to a fire water pipe through a pipeline.
[0028] In this embodiment, the absorption tower with safety fire-fighting device is equipped with a fire sprinkler device 2 at the top inside the traditional absorption tower. The fire sprinkler device 2 is connected to a fire water pipe. When a fire occurs inside the tower, the fire sprinkler device 2 can respond in time and spray water downwards from the top inside the absorption tower body 1. This avoids situations where fire extinguishing is not timely due to temporary measures taken by operators, or where temporary measures are ineffective in extinguishing the fire due to unprofessionalism or negligence of the personnel who took them.
[0029] As a preferred implementation method, such as Figure 2 As shown, a branch pipeline 3 is vertically fixed on the outside of the side wall of the absorption tower body 1. The branch pipeline 3 is connected at intervals to the upper and lower parts of the first nozzle 31 that extends into the interior of the absorption tower body 1. The upper end of the branch pipeline 3 is connected to a fire water pipe through a pipeline.
[0030] In the above implementation scheme, while a fire sprinkler device 2 is installed at the top of the tower, a branch pipeline 3 is installed on the side wall of the main body 1 of the absorption tower. The branch pipeline 3 is equipped with a first nozzle 31 at different heights inside the tower. When a fire occurs, the external fire water can enter the branch pipeline 3 to spray at different heights inside the tower. In conjunction with the top sprinkler, it can maximize the effect of curbing the spread of fire and extinguishing the fire in time.
[0031] In a preferred embodiment, the upper end of the branch pipeline 3 is connected to the fire sprinkler device 2 via a common pipeline, and a fire water pipe is connected to the outside through this pipeline.
[0032] In the above implementation scheme, the branch pipeline 3 merges with the water supply pipeline of the fire sprinkler device 2, and the two are connected to the fire water pipe, making the supply of fire water relatively simple and quick.
[0033] In this embodiment, multiple branch pipelines 3 are provided and distributed at intervals around the main body 1 of the absorption tower. That is to say, multiple first nozzles 31 are set around each different height to spray at a fixed point, resulting in a better fire extinguishing effect.
[0034] As a preferred implementation method, such as Figure 3 As shown, the fire sprinkler system 2 includes a horizontal pipe 21 and multiple vertical pipes 22. One end of the horizontal pipe 21 is provided with a water inlet, which penetrates the main body of the absorption tower 1 and is connected to the fire water pipe through a pipeline. The multiple vertical pipes 22 are distributed parallel to each other at intervals and intersect the horizontal pipe 21 perpendicularly, and are connected and communicated at the intersection. The lower end of the horizontal pipe 21 and the lower end of the multiple vertical pipes 22 are respectively connected to a second nozzle a.
[0035] In the above implementation scheme, the fire sprinkler device 2 adopts horizontal pipes 21 and vertical pipes 22 arranged in a crisscross pattern. Multiple second nozzles are arranged on the horizontal pipes 21 and vertical pipes 22. The spray area of each second nozzle is a circular area. The spray areas of two adjacent second nozzles partially overlap. This design ensures that the multiple second nozzles of the entire fire sprinkler device 2 fully cover the cross section of the tower, and there are no blind spots in the spray, resulting in a better fire extinguishing effect.
[0036] In a preferred embodiment, the ends of the horizontal tube 21 and the vertical tube 22 are connected to annular support rings 23, and L-shaped support members 11 are provided circumferentially on the inner wall of the top of the absorption tower body 1, and the support rings 23 are inserted into the support members 11.
[0037] In the above implementation scheme, multiple support members 11 are arranged circumferentially at intervals on the top side wall inside the tower. When installing the fire sprinkler device 2, it is only necessary to insert the outer support ring 23 into the multiple support members 11 and then pass the water inlet of the fire sprinkler device 2 through the side wall of the tower, which is very convenient.
[0038] As a preferred implementation method, such as Figure 4 As shown, the fire sprinkler system 2 includes a ring-shaped main pipe 24, which is fixed to the inner wall of the top of the absorption tower body 1. Multiple third nozzles b are spaced apart on the inner side of the main pipe 24. The main pipe 24 is connected to a horizontal water inlet pipe that penetrates the side wall of the absorption tower body 1. The water inlet pipe is connected to a fire water pipe through a pipeline.
[0039] In the above implementation scheme, the fire sprinkler device 2 has a simple structural design and a large internal flow area, which will not obstruct the normal passage of smoke. At the same time, it can achieve full coverage of the cross-section area by avoiding the dense and angled third sprinkler heads. The design is also relatively reasonable and simple.
[0040] As a preferred implementation method, such as Figure 5 As shown, it also includes a control system, which includes a controller, a temperature measuring device 5 and an electrically controlled valve 6. The electrically controlled valve 6 is installed on the pipeline connected to the fire sprinkler device 2. The temperature measuring device 5 is installed at the top of the absorption tower body 1 and is used to detect the internal temperature of the top of the absorption tower body 1. The controller is connected to the temperature measuring device 5 and the electrically controlled valve 6 respectively.
[0041] In the above implementation scheme, during the operation, the temperature measuring device 5 monitors the flue gas temperature at the top of the tower in real time. If the flue gas temperature is abnormal (rising above the set value), it indicates an abnormality inside the tower and the presence of a fire. The controller will immediately control the electric control valve 6 to open, thereby allowing external fire water to enter the pipeline and spray into the fire sprinkler device 2. The entire fire-fighting device responds very quickly and promptly, and can effectively curb the further development of the fire in its early stages and extinguish the fire quickly.
[0042] In this embodiment, the controller is also connected to an alarm. Once the temperature measuring device 5 detects an abnormal increase in the temperature of the flue gas inside the tower, the controller will control the alarm to issue an audible and visual alarm to promptly warn the workers on site.
[0043] In this embodiment, the temperature measuring device 5 is a thermocouple of the appropriate type.
[0044] In this embodiment, an inspection port is provided on the top side wall of the absorption tower body 1, and a climbing ladder is provided on the side wall of the absorption tower body 1. This facilitates the workers to climb up and down and to perform routine maintenance work on the fire sprinkler system 2 through the inspection port.
