Description

Technical Field

[0001] This utility model relates to the technical field of safety protection, and in particular to a fresh air system for a hazardous waste storage warehouse. Background Technology

[0002] Hazardous waste storage warehouses are crucial facilities for storing and treating hazardous waste. Due to the corrosive, toxic, and flammable nature of hazardous waste, the requirements for the storage environment are extremely high. As a vital component of hazardous waste storage warehouses, the fresh air system's primary function is to maintain fresh air within the warehouse, prevent the accumulation of harmful gases, thereby protecting the health and safety of personnel and reducing the possibility of environmental pollution and accidents. In hazardous waste storage warehouses, the fresh air system is typically used in conjunction with the exhaust system to form a complete ventilation system. Fresh air is introduced through the fresh air system, while exhaust gases are expelled from the warehouse, maintaining air circulation and ensuring that air quality meets standards. Furthermore, the fresh air system can be adjusted according to the type and quantity of hazardous waste stored in the warehouse to ensure optimal ventilation.

[0003] For example, in a prior art represented by application number CN202321387931.2, the main structure includes an exhaust duct installed above the hazardous waste storage room. One end of the exhaust duct is bent and opens downwards to form a gradually expanding exhaust port, while the other end extends out of the hazardous waste storage room. The tail end of the exhaust duct has an explosion-proof exhaust motor, and the exhaust duct also contains an activated carbon filter box. This utility model's hazardous waste storage room exhaust system solves the potential hazard of directly releasing hazardous air from the hazardous waste storage room to the outside, reducing the risk of personal injury and environmental pollution.
