Description

Technical Field

[0001] This utility model relates to the field of hazardous chemical warehouse detection technology, and more specifically, to a hazardous chemical warehouse gas detection and treatment device. Background Technology

[0002] As a place where hazardous chemicals are stored in a concentrated manner, the safety of hazardous chemical warehouses is of paramount importance. Hazardous chemicals in the warehouse may release toxic and harmful gases, such as chlorine, hydrogen sulfide, and benzene, due to reasons such as damaged packaging or leakage. These gases not only pose a direct threat to the life and health of warehouse workers, but may also cause serious accidents such as fires and explosions. Therefore, it is necessary to detect the gases in the warehouse to prevent accidents and ensure the safety of personnel and the environment.

[0003] Hazardous chemicals are generally stored in warehouses, requiring monitoring of gas concentrations within the warehouses. When gas concentrations exceed the limits, they need to be discharged promptly. However, existing monitoring and treatment devices need to operate separately, which prevents timely handling and results in low efficiency.

[0004] A search revealed Chinese patent CN217587134U, which discloses a hazardous chemical warehouse gas concentration detection and treatment device. This structure utilizes a processor, gas concentration detectors, and ventilation ducts working in tandem. The control center pre-plans the detection route and transmits it to a signal receiver. The gas concentration detectors monitor the warehouse gas concentration in real time. Once a concentration exceeding the limit is detected, a signal is immediately transmitted to the processor, which then forwards it to the control center. The control center then opens the exhaust vents and exhaust fans. Simultaneously, the processor starts the ventilation duct and a rotating motor. The motor drives the shaft, gears, and rotating base, causing the ventilation duct to rotate and accelerating gas discharge, achieving comprehensive monitoring and rapid handling of exceeding limits. Furthermore, the system includes an electric actuator and detector clamps. Activating the electric actuator moves the clamps, facilitating the fixing and disassembly of the gas concentration detectors, simplifying maintenance, effectively saving equipment costs, and improving monitoring efficiency and effectiveness.

[0005] However, in actual use, while the structure can effectively remove hazardous gases from the warehouse and introduce fresh air under different gas leakage conditions through the exhaust fan, the direct discharge of hazardous gases and harmful gases will pollute the surrounding environment.

[0033] Working principle of this utility model:

[0034] This utility model is a gas detection and treatment device for hazardous chemical warehouses. When in use, the multiple casters 29 at the bottom of the support frame 1 make the entire device easy to move within the hazardous chemical warehouse. The position can be adjusted according to the actual detection and treatment needs. The solenoid valve is opened to pour the treatment liquid from the feed pipe 6 into the storage box 5. The storage box 5 is used to store and distribute the treatment liquid as a neutralizing solution for acidic or alkaline gases. Under the control of the solenoid valve, the feed pipe 6 can quantitatively add the treatment liquid into the storage box 5 to complete the preparation work.

[0035] Next, the gas concentration detector 24 is placed between the clamping plates 23. The clamping plates 23 can adjust the clamping force on the gas concentration detector 24 under the action of the electric telescopic rod 22 to ensure its stability. The gas concentration detector 24 uses the corresponding sensing technology to transmit the detected electrical signal to the processor 25 for analysis and processing. After receiving the signal from the gas concentration detector 24, the processor 25 analyzes and judges according to the preset dangerous gas concentration threshold. If the detected gas concentration exceeds the threshold, the processor 25 triggers the audible and visual alarm 28 through the controller 27 to alert the staff in the form of sound and light.

[0036] Furthermore, the controller 27 controls the start of the ventilation fan 2. The air containing hazardous gases in the hazardous chemical warehouse is transported to the treatment box 3 through the pipe 3 under the suction of the ventilation fan 2. Multiple through holes on the surface of the gas equalization plate 4 make the hazardous gases transported to the treatment box 3 rise evenly. At the same time, the controller 27 controls the start of the circulating water pump 10, which draws out the treatment liquid in the storage box 5 through the circulation pipe 11 and sprays it out from multiple spray heads 9 at the bottom of the spray pipe 7. These droplets come into full contact with the gas entering the treatment box 3. According to the chemical reaction principle of acid-base neutralization, the gas reacts with the acidic or alkaline toxic gas. The alkaline treatment liquid is used to neutralize the gas and convert it into harmless substances.

[0037] After being sprayed, the gas continues to rise into the adsorption frame 12. Inside the adsorption frame 12, the fixed net 14 at the bottom of the mounting frame 13 fixes the activated carbon plate 15. The activated carbon plate 15 has a rich porous structure. Utilizing the physical adsorption principle of activated carbon, it adsorbs residual organic gases and other harmful gases in the gas, further purifying the gas. The purified gas continues to flow upward and is discharged through the exhaust pipe 19. The dust removal net 20 on one side of the exhaust pipe 19 can prevent the discharge of any small particulate matter that may be carried, ensuring the cleanliness of the discharged gas.

[0038] The door 16, which is hinged on one side of the adsorption frame 12, can be opened and closed and fixed by the snap-fit ​​between the connecting strip 17 and the connecting frame 18. When the activated carbon plate 15 is saturated and needs to be replaced or maintained, the door 16 can be opened for operation.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
