Solid waste extraction system and method thereof

Abstract

The invention provides a solid waste extraction system and a method thereof. The system comprises an extraction liquid adding part, an oscillating extraction part and an extract collecting part. The extraction liquid adding part comprises a liquid adding device, an extraction device and a pressurizing device. The oscillating extraction part comprises the extraction device and an overturning type oscillator. The extract collecting part comprises the pressurizing device, the extraction device and a collecting device. The devices are connected through connecting pieces. According to the system and method provided by the invention, by adoption of the liquid adding device, extraction reactants are added into the extraction device, extraction reaction is completely conducted under oscillation of the overturning type oscillator, and extract is collected into the collecting device through a filtering effect of the extraction device; the system is high in airtightness so that overflowing of harmful gas can be effectively prevented; the collecting device can be used for collecting liquid and gas; and through the method provided by the invention, toxicant substances in solid waste can be effectively extracted, and a reasonable scheme can be provided for subsequent solid waste treatment modes.

Description

technical field [0001] The invention belongs to the technical field of environmental treatment equipment, and belongs to the technical field of pollutant storage, transfer, filtration and leaching systems, and in particular relates to a solid waste leaching system and a method thereof. Background technique [0002] With the development of society and the acceleration of people's life rhythm, more and more wastes are produced, especially some solid wastes, which are huge in quantity and cause serious pollution. Different wastes have different treatment methods. At present, the main treatment methods are: landfill, biological fertilizer method and incineration. The landfill method is mature, but the initial investment is large, and a lot of land resources are wasted; the biological fertilizer method covers a large area, the process is complicated, it is highly dependent on temperature, the processing speed is slow, there is strong odor pollution, and the bacteria are easy to ...

AI Technical Summary

Problems solved by technology

[0005] The existing laboratory solid waste leaching toxicity equipment has the following disadvantages: 1) the connection mode of each accessory is complicated; 2) the airtightness of the equipment is not enough, and the situation of toxic substance leakage occurs; 3) the pressurization equipment is heavy, Long pipeline connections are required; 4) The overturning of the oscillator is too simple, only plane oscillation, so that the extraction reaction is not comprehensive enough, and the temperature is not constant enough; 5) The storage and measurement of toxic substances are inconvenient, etc.

[0006] In the existing method for leaching toxic substances, the toxic gas cannot be measured or detected, the airtightness is not enough, the oscillation reaction is not violent enough, and there are shortcomings such as incomplete extraction or long oscillation reaction time.
