A Traceable Liquid Hazardous Waste Safe Unloading System

Abstract

The invention provides a traceable safe unloading system for liquid hazardous wastes. According to the traceable safe unloading system for the liquid hazardous wastes, inlets and outlets are arrangedwithin a certain area; a material temporary storage area is arranged in the area and the material temporary storage area is divided into a plurality of small areas; the small areas are marked by different colors and each small area is divided into a qualified material area and a unqualified material area; material barrels corresponding to the colors of the small areas are placed in the corresponding small areas and radio-frequency identification codes are arranged on the material barrels; conveying belts are correspondingly arranged at the two sides of the material temporary storage area; a plurality of material unloading areas, barrel washing areas, drying areas and leakage detecting areas are sequentially arranged on the conveying belts and empty barrel storage areas are arranged at thetails of the conveying belts. According to the system, hazardous waste containers are unified and the radio-frequency identification codes are arranged, therefore the functions of being traceable without the need for manual recording and convenient for taking trace can be realized; the full-automatic continuous operation of material unloading and cleaning of the material barrels can be realized, so that the working efficiency is improved and the safety is guaranteed.

Description

technical field [0001] The invention relates to the field of hazardous waste treatment, in particular to a system for safely unloading traceable liquid hazardous waste. Background technique [0002] Hazardous waste is a special kind of waste, which is produced in a small amount, has complex components, and has a wide variety of types. It is toxic, explosive, flammable, corrosive, chemically reactive, radioactive, and other hazards, and may cause harmful effects on the environment or human health. , with long-term and latent characteristics. Hazardous waste can be divided into solid hazardous waste and liquid hazardous waste. At present, solid hazardous waste is treated by SMP treatment system, and only one company in the world is doing it. [0003] Liquid hazardous waste has its own characteristics different from solid hazardous waste. It often has high salt, high toxicity, and is more likely to cause harm to the human body. The current practice is to put liquid waste into ...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, there are many problems in the liquid hazardous waste unloading link: 1. The containers used to hold the liquid hazardous waste are not uniform and not classified, and different types of hazardous waste containers are mixed. In addition, the cleaning process of the containers is not thorough, which will cause the containers to be damaged. Corrosion, material leakage during transportation; chemical reactions of different types of residues in the barrel, not only has the risk of explosion, but also causes unorganized gas emissions; the mixing of different materials brings greater risks to manual dumping of barrels, and in the pit The mixture of materials with different properties may cause fires from time to time

2. In waste production enterprises and corresponding hazardous waste treatment enterprises, the entry and exit of materials are still carried out by manual registration, and the classification of materials is also manually carried out by technicians. It is difficult to track hazardous waste materials throughout the process, and there are major safety hazards in the treatment process; 3. After the hazardous waste from the waste production enterprise arrives at the hazardous waste treatment enterprise, the unloading is still a manual operation. It needs to be manually opened, dumped or pumped to the corresponding storage tank. During this process, there is a major threat to the hazards of personnel. Although Operators are equipped with protective devices such as gas masks, respirators, goggles, etc., but there are still insufficient protection levels or omissions; sometimes operators do not know the interaction between materials due to their lack of knowledge and protection awareness, which will cause serious accidents. Safety accidents, in news reports in recent years, such casualties are not uncommon; according to the case disclosed by the State Administration of Security, in 2017, Shandong Yantai Xinguang Lvhuan Company only lost control of the process of the unloading unit of the liquid hazardous waste process, causing casualties 17 people, 5 people died on the spot in a major safety accident

4. At present, the unloading treatment operation of domestic liquid hazardous waste cannot achieve continuous work, the degree of automation is low, the overall unloading time is long, and the processing efficiency is low
