Oily impermeable cloth closed feeding system and feeding method

Abstract

The invention relates to the field of hazardous waste treatment. The invention provides a closed feeding system for oil-containing impermeable cloth. The closed feeding system comprises a grab bucket weighing and feeding device, a first-stage storage bin, a shredding machine, a second-stage storage bin, a conveyor with a closed cover, a flexible connecting pipe, a feeding device, a moving device and a rotary kiln pyrolysis device. The grab bucket weighing and feeding device is mounted above an inlet of the first-stage storage bin; openings of the grab bucket weighing and feeding device and the first-stage storage bin are formed in a closed space; an outlet of the primary storage bin is connected with an inlet of the shredder; an outlet of the shredder is connected with an inlet of the secondary storage bin; an outlet of the second-stage storage bin is connected with an inlet of the conveyor with the sealing cover, and the outlet of the second-stage storage bin faces a conveying belt of the conveyor with the sealing cover; an outlet of the conveyor with the closed cover is connected with one end of the flexible connecting pipe; the other end of the flexible connecting pipe is connected with the feeding device; the feeding device is connected with the moving device. The invention further provides a closed feeding method of the oil-containing anti-seepage cloth. Through the implementation of the invention, the safety of employees and the environment of a factory can be effectively protected.

Description

technical field [0001] The invention relates to the field of hazardous waste treatment, in particular to the treatment of oily anti-seepage cloth used in the process of oil production. Background technique [0002] Oily anti-seepage cloth refers to the anti-seepage cloth used to prevent crude oil or refined oil from being mixed into soil and other media during mining or oil well leakage rescue. Waste categories HW08 and HW49 in the Waste List. Oily impermeable fabrics generally contain benzene series, phenols, anthracene and other substances, accompanied by stench and toxicity. If they come into direct contact with the natural environment, they will cause serious pollution to soil, water and vegetation. One of the disposal methods of ordinary oily anti-seepage cloth is pyrolysis under anaerobic and anoxic conditions, using heat to decompose sludge to produce oil, volatile gas and clean soil. However, due to the characteristics of miscellaneous materials and uneven characte...

AI Technical Summary

Problems solved by technology

However, due to the characteristics of miscellaneous materials and uneven characteristics of oily impermeable cloth, traditional continuous pyrolysis furnaces cannot continuously and effectively dispose of them, while batch type pyrolysis furnaces cannot guarantee the health and safety of workers due to the need for manual intervention in feeding materials. The VOC gas volatilized from oil sludge cannot be effectively collected, so the safe and efficient disposal of oily anti-seepage cloth has become a major problem
