Description

TECHNICAL FIELD

[0001] The utility model relates to the field of hazardous waste treatment, more specifically, it relates to a filtering and subpackaging integrated equipment for liquid hazardous waste treatment. BACKGROUND

[0002] In the field of liquid hazardous waste treatment, effective filtration is one of the key steps to ensure the safety and compliance of waste disposal. Traditional liquid hazardous waste filtration systems generally use filters filled with multiple layers of filtration materials. These filtration layers are composed of different materials, aiming to gradually remove impurities and pollutants in the waste, to achieve the purpose of purification or pretreatment. However, in practical application, this multi-layer filtration structure has several significant problems:

[0003] First layer material prone to clogging and resource waste: Due to the complex composition of liquid hazardous waste, it often contains a large amount of particulate or viscous substances. These substances first contact and deposit on the first layer of filtration material when passing through the filter, causing the first layer to clog and affecting filtration efficiency. The traditional approach is to disassemble and replace the entire filter once the first layer is clogged, resulting in the waste of the un-clogged bottom layer materials in the filter, causing significant resource waste.

[0004] Safety hazards during filling process: After filtration, liquid hazardous waste is usually filled into storage tanks through special subpackaging devices for subsequent processing or transportation. The current operation process is that when the liquid in the storage tank reaches the preset amount, the valve of the subpackaging device automatically closes, and the inlet valve of the storage tank also closes accordingly. However, during this process, there is a certain amount of liquid hazardous waste remaining between the subpackaging device valve and the storage tank valve. If the storage tank is removed directly at this time, these residual liquids may leak due to improper operation or system pressure changes, posing a safety hazard to operators and the environment, and also violating strict safety production regulations.
