Description

Technical Field

[0001] This utility model relates to the field of fire hazard gas removal technology, specifically a rapid fire hazard gas removal device. Background Technology

[0002] For certain underwater work compartments or special enclosed work compartments, the space is small, and flammable materials are concentrated in large quantities. If a fire breaks out, the smoke is difficult to disperse, resulting in a significant fire hazard. External rescue is also difficult, posing a great threat to the safety of equipment and personnel. Therefore, it is crucial to quickly restore visibility and the working environment after a fire is controlled in its early stages or a small fire is extinguished. This requires restoring visibility and a certain working environment within the enclosed compartment without relying on surfacing or external rescue ventilation. This can be achieved through rapid elimination of harmful fire gases. This is of great significance for ensuring the safety of personnel in underwater work compartments or special enclosed work compartments, and for quickly restoring the ability to work within enclosed compartments after an early fire has been extinguished.

[0003] Therefore, to solve the above problems, we provide a rapid fire hazard gas removal device to quickly remove smoke particles and hazard gases after an early fire. Utility Model Content

[0033] In use: First, the smoke particle filter unit 1, CO removal unit 2, and CO2 / SO2 adsorption unit 3 can be quickly connected via the spring quick-release buckle 5. External smoke particles pass through the smoke particle removal filter element 06 from the outside to the inside under the action of the centrifugal fan 05, effectively intercepting particulate matter and tar particles in the medium. Then, the CO removal filter element 07, through the spraying of precious metal catalysts such as palladium, platinum, and rhodium on the iron-chromium-aluminum substrate, catalyzes and reduces invisible CO, HC compounds, and visible white smoke and other harmful gases. A shaped heater is then added in front of the substrate. The heat medium is heated to approximately 200°C, which enhances the catalytic reduction of the filter element, maximizes the utilization rate of precious metals, and improves the conversion and removal efficiency of CO and HC compounds. Finally, the gas enters the CO2 removal housing 03 and is removed by the CO2 / SO2 removal filter element 08 through an upgraded LiOH spherical adsorbent preparation process. Utilizing the chemical reaction adsorption principle of the LiOH spherical adsorbent in the filter element, CO2 / SO2 in the medium is removed. Furthermore, this device can be assembled with any three modules as needed, and can be directly removed when CO removal or CO2 / SO2 removal is not required.
