[0034] Figure 1 This is a schematic diagram of a desulfurization absorption tower with a fire-fighting device according to an embodiment of the present invention. Figure 1As shown, the desulfurization absorption tower with fire-fighting device includes a tower body 1, a driving assembly (not shown), a universal head 2, a nozzle 3, a water inlet main pipe 4, a first water inlet branch pipe 5, a fire detection mechanism 6, a controller 7 and an alarm (not shown). The driving assembly is installed in the tower body 1; the universal head 2 is connected to the driving assembly and rotates under the drive of the driving assembly; the nozzle 3 is fixedly connected to the universal head 2; the first electric control valve 8 is installed on the water inlet main pipe 4; the first water inlet branch pipe 5 connects the water inlet main pipe 4 and the nozzle 3; the fire detection mechanism 6 is installed in the tower body 1, and is used to detect the fire situation in the tower body 1 in real time; the input end of the controller 7 is connected to the output end of the fire detection mechanism 6 in communication, and the output end of the controller 7 is connected to the driving assembly and the control end of the first electric control valve 8 in communication; the input end of the alarm is connected to the output end of the controller 7 in communication.

[0035] When personnel need to enter the tower body 1 for maintenance and other operations, the fire detection mechanism 6 is started, and the fire detection mechanism 6 monitors the fire situation in the tower body 1 in real time, and transmits the monitored fire data to the controller 7 in real time. The controller 7 receives the fire data, analyzes and determines whether there is a fire point and the position of the fire point. When there is a fire situation, the controller 7 outputs an alarm signal to the alarm, controls the alarm to sound an alarm, and prompts the operator to evacuate as soon as possible. At the same time, the controller 7 outputs an opening signal to the control end of the first electric control valve 8 to control the first electric control valve 8 to open, and outputs a driving signal to the control end of the driving component to activate the driving component, thereby driving the universal head 2 and the nozzle 3 connected to the universal head 2 to rotate to the position toward the fire point, so that the water source is sprayed toward the fire point through the water inlet main pipe 4, the first water inlet branch pipe 5 and the nozzle 3 to carry out directional fire extinguishing.

[0036] By using the desulfurization absorption tower with fire-fighting device of the present invention, the controller 7 controls the alarm to sound an alarm to prompt personnel to evacuate according to the monitoring result of the fire detection mechanism 6, and controls the driving component to drive the universal head 2 and the nozzle 3 to rotate, and performs directional water spraying to extinguish the fire at the fire point, thereby ensuring the safety of the operating personnel during maintenance and other work processes.

[0037] like Figure 1As shown, in this embodiment, a smoke inlet is provided at the lower end of the tower body 1, and a smoke outlet is provided at the upper end. Multiple groups of universal heads 2 and nozzles 3 are provided, which are arranged at different positions of the upper, middle and lower parts of the tower body 1, respectively. Correspondingly, multiple groups of drive components are also provided to drive the universal heads 2 at different positions to rotate, and multiple first water inlet branches 5 are also provided to connect the water inlet main pipe 4 and the corresponding nozzles 3, respectively. The alarm can be a sound alarm or a light alarm, as long as it can remind people to evacuate. The fire detection mechanism 6 can be any mechanism that can detect whether there is a fire in the tower body 1 and the position of the fire point, and it can be arranged at any position in the tower body 1 to facilitate monitoring of the fire situation. The drive component can be composed of any structure, as long as it can drive the universal head 2 and the nozzle 3 to rotate to the position toward the fire point after receiving the drive signal of the controller 7. For example, the drive component can include a motor and a transmission member, the motor receives the signal output by the controller 7, drives the transmission member to move, and the transmission member is connected to the universal head 2 to drive the universal head 2 to rotate.

[0038] Optionally, the desulfurization absorption tower with fire-fighting device further includes a second water inlet branch pipe 9 and an atomizing nozzle 10. The first end of the second water inlet branch pipe 9 is connected to the water inlet main pipe 4, and the second end of the second water inlet branch pipe 9 passes through the tower body 1; the atomizing nozzle 10 is connected to the second end of the second water inlet branch pipe 9. In this arrangement, when the fire detection mechanism 6 detects that there is a fire in the tower body 1, after the first electric control valve 8 is controlled to open, the water source is not only sprayed toward the fire point through the first water inlet branch pipe 5 and the nozzle 3, but also sprayed through the second water inlet branch pipe 9 through the atomizing nozzle 10, and the two cooperate to achieve joint fire extinguishing.

[0039] like Figure 1 As shown, in this embodiment, a total of four second water inlet branches 9 are provided, which are spaced to penetrate the top of the tower body 1, and each second water inlet branch 9 that penetrates one end of the tower body 1 is connected to an atomizing nozzle 10. When a fire is detected, the controller 7 controls the first electric control valve 8 to open, and the water source is sprayed from the top of the tower body 1 through the water inlet main pipe 4, the second water inlet branch 9 and each atomizing nozzle 10, which can cover the entire internal space of the tower body 1 to the greatest extent. In this embodiment, the atomizing nozzle 10 uses a spiral atomizing nozzle 10, and the angle of the atomizing nozzle 10 is set to 120°. According to the actual application, the number of second water inlet branches 9 and the specific connection position with the tower body 1 can be adjusted, and accordingly, the number of atomizing nozzles 10 is adjusted accordingly.

[0040] Optionally, the desulfurization absorption tower with a fire-fighting device further includes a temperature sensor 11, which is used to monitor the temperature data in the tower body 1, and the output end of the temperature sensor 11 is communicatively connected to the input end of the controller 7. If the temperature in the tower body 1 is too high, it also indicates that a fire point may have occurred, so the controller 7 can control the opening and closing of the first electric control valve 8 according to the temperature change in the tower body 1.

[0041] The temperature sensor 11 monitors the temperature data in the tower body 1 in real time, and transmits the monitored temperature data to the controller 7 in real time. The controller 7 has a preset temperature threshold stored in it. When the received temperature data is greater than the preset temperature threshold, it indicates that the temperature in the tower body 1 is too high and a fire point may appear. At this time, the controller 7 controls the alarm to sound an alarm, and at the same time controls the first electric control valve 8 to open, so that water flows through the water inlet main pipe 4 and enters each first water inlet branch pipe 5 and the second water inlet branch pipe 9 respectively, and is sprayed out through each nozzle 3 and the atomizing nozzle 10 to extinguish the fire. In this embodiment, three temperature sensors 11 are provided, which are distributed at intervals on the top of the tower body 1. The output end of each temperature sensor 11 is connected to the input end of the controller 7 in communication. When the temperature data monitored by any temperature sensor 11 exceeds the preset temperature threshold, the controller 7 controls the first electric control valve 8 to open. According to the actual application, the number of temperature sensors 11 and the specific setting position in the tower body 1 can be adjusted. The controller 7 controls the alarm to work according to the temperature data change, and controls the control logic of opening and closing the first electric control valve 8, which can be realized according to the existing mature algorithms, and its specific working principle will not be repeated here.

[0042] Optionally, the desulfurization absorption tower with fire fighting device further comprises a high-pressure water tank (not shown), the outlet of which is connected to the water inlet pipe 4. The high-pressure water tank can provide water source for the water inlet pipe 4 at any time, and can ensure that the water source is connected as soon as a fire occurs.

[0043] Optionally, the fire detection mechanism 6 is set as an infrared thermal imager. With the help of the infrared thermal imager, the infrared imaging data in the tower body 1 can be obtained in real time, and the infrared imaging data can be transmitted to the controller 7 in real time. The controller 7 can accurately determine whether there is a fire and the specific location of the fire point according to the internal preset program. If there is a fire, the controller 7 controls the first electric control valve 8 to open, and controls the action of the drive component to rotate the universal head 2 and the nozzle 3 to the position toward the fire point. The controller 7 controls the opening and closing of the first electric control valve 8 according to the infrared imaging data, and the control logic of controlling the action of the drive component can be realized according to the existing mature algorithm, and its specific working principle will not be repeated here.

[0044] Optionally, the desulfurization absorption tower with fire-fighting device further includes a toxic and harmful gas detector 12, which is installed in the tower body 1, and its output end is communicatively connected with the input end of the controller 7. With the help of the toxic and harmful gas detector 12, the gas in the tower body 1 can be monitored in real time, and when the concentration of toxic and harmful gas exceeds the standard, the alarm is controlled by the controller 7 to sound an alarm, so as to prompt the operator to evacuate immediately.

[0045] The toxic and harmful gas detector 12 monitors the toxic and harmful gas concentration data in the tower body 1 in real time, and transmits the toxic and harmful gas concentration data to the controller 7. The controller 7 has a preset concentration threshold stored in it. When the received toxic and harmful gas concentration data is greater than the preset concentration threshold, it indicates that the toxic and harmful gas concentration in the tower body 1 exceeds the standard. At this time, the controller 7 controls the alarm to sound an alarm, prompting personnel to evacuate quickly. The control logic of the controller 7 controlling the alarm to sound an alarm according to the change of the toxic and harmful gas concentration data can be realized according to the existing mature algorithm, and its specific working principle will not be repeated.

[0046] Optionally, the desulfurization absorption tower with fire-fighting device further includes an air intake main pipe 13 and a plurality of air intake branch pipes 14. The air intake main pipe 13 penetrates and extends into the tower body 1, and a second electric control valve 15 is installed on the air intake main pipe 13, and the control end of the second electric control valve 15 is communicatively connected with the output end of the controller 7; and the plurality of air intake branch pipes 14 are connected with the air intake main pipe 13 in the tower body 1. In this arrangement, when it is detected that the concentration of toxic and harmful gases in the tower body 1 exceeds the standard, the controller 7 can control the second electric control valve 15 to open, and introduce external air into the tower body 1, so as to reduce the concentration of toxic and harmful gases in the tower body 1.

[0047] The toxic and harmful gas detector 12 monitors the toxic and harmful gas concentration data in the tower body 1 in real time, and transmits the toxic and harmful gas concentration data to the controller 7. When the toxic and harmful gas concentration data received by the controller 7 is greater than the preset concentration threshold, it indicates that the toxic and harmful gas concentration in the tower body 1 exceeds the standard. At this time, the controller 7 controls the alarm to sound an alarm, prompting the operator to evacuate the tower body 1. At the same time, the second electric control valve 15 is controlled to open, and high-pressure air is dispersedly blown into the tower body 1 through the air intake main pipe 13 and the connected air intake branch pipes 14 to reduce the toxic and harmful gas concentration in the tower body 1.

[0048] Optionally, the desulfurization absorption tower with fire-fighting device further comprises a compressed gas source, the outlet of which is connected to the air intake pipe 13. The compressed gas source can provide an air source for the air intake pipe 13 at any time, and can ensure that the gas source is connected as soon as the concentration of toxic and harmful gases exceeds the standard.

[0049] Optionally, a check valve 16 is installed on the water inlet pipe 4. The check valve 16 can prevent the water flowing through the water inlet pipe 4 from flowing in the reverse direction, which affects the normal fire extinguishing.

[0050] Optionally, a manual valve 17 is installed on the water inlet pipe 4. During the normal operation of the desulfurization absorption tower, it is not necessary to spray water into the tower body 1 through the water inlet pipe 4. During this process, the manual valve 17 can be closed to ensure that the water inlet pipe 4 is completely closed, and water will not flow into the tower body 1 through the water inlet pipe 4 due to the first electric control valve 8 being damaged and not closed tightly.

[0051] like Figure 1 As shown, in this embodiment, a manual valve is also installed on each second water inlet branch pipe 9. During normal operation of the desulfurization absorption tower, the manual valves 17 on the water inlet main pipe 4 and the second water inlet branch pipe 9 are closed at the same time to ensure that water does not enter the tower body 1.
