Abstract
Description
Technical Field
[0001] This utility model relates to hazardous waste management, and more specifically, to a hazardous waste storage and transportation container. Background Technology
[0002] Hazardous waste is waste that poses a threat to the ecological environment and human health due to its toxicity, corrosiveness, flammability, and explosiveness. Moreover, with rapid industrial development, the amount of hazardous waste generated is increasing daily. Once hazardous waste is leaked, it can cause serious pollution to soil, water bodies, and air, endangering the ecological environment and human health.
[0003] Chemical enterprises are more likely to generate hazardous waste than other enterprises. Therefore, chemical enterprises need to manage hazardous waste in a special way. Hazardous waste containers, as containers for hazardous waste, are key equipment for hazardous waste management.
[0004] Existing hazardous waste containers are generally made of iron drums, plastic drums, woven bags, etc., and when used for storage, iron drums and plastic drums do not even have matching lids.
[0005] Existing hazardous waste containers have the following shortcomings:
[0006] (1) Sealing problem: Even if existing hazardous waste containers are sealed, the sealing structure is relatively simple, usually relying on a single rubber sealing ring. During long-term storage or transportation, the sealing ring is prone to aging and deformation due to factors such as temperature changes and vibration, resulting in a decline in sealing performance and an increased risk of hazardous waste leakage.
[0007] (2) Insufficient protection: Existing hazardous waste containers have limited protective measures, and the material strength of the container is insufficient or lacks an effective buffer structure. They are easily damaged when subjected to external impact, which can lead to hazardous waste leakage accidents.
[0008] (3) Inconvenient labeling and management: Different types of hazardous waste require clear and accurate labeling for classified management; however, the labeling areas of existing hazardous waste containers are not obvious or the labels are easily worn, which is not conducive to rapid identification and information management.
[0009] (4) Lack of pressure balancing design: During storage, hazardous waste may produce gas due to its own chemical reactions or changes in ambient temperature, which may cause the internal pressure of the container to rise. Some existing hazardous waste containers do not have effective pressure balancing measures. Excessive pressure may damage the container or even cause serious consequences such as explosion.
[0010] (5) Lack of traceability: Existing hazardous waste containers cannot provide information on the entire lifecycle of hazardous waste from generation to disposal. Utility Model Content
