Multiphase organic waste comprehensive feeding pyrolysis device

Abstract

The invention provides a multiphase organic waste comprehensive feeding pyrolysis device. The device comprises a slurry storage tank, a grating, an oil pump, a stock bin, a spiral feeder, a double-roller type extrusion feeding device, a slurry feeding device and a chain plate type pyrolysis device. When the device runs, a high-liquid-content material is fed into the slurry storage tank, large-particle solid impurities in the high-liquid-content material are filtered out through the grating, the high-liquid-content material is fed into the stock bin, the filtered high-liquid-content material is conveyed to the slurry feeding device through the oil pump, and the filtered high-liquid-content material is uniformly distributed under the action of a material distribution plate and a grating plate of the slurry feeding device and enters a pyrolysis reactor; and on the other hand, a high-solid-content material is fed into the stock bin, conveyed to the double-roller type extrusion feeding device through the spiral feeder at the bottom of the stock bin, and uniformly enter the pyrolysis reactor after being extruded and extended by a roller shaft of the double-roller type extrusion feeding device. The device is exquisite and compact in structural design and easy to operate and maintain, and uniform and stable feeding and efficient pyrolysis of the multiphase organic waste can be achieved.

Description

technical field [0001] The invention belongs to the technical field of organic waste treatment and utilization, in particular to a multi-phase organic waste comprehensive feed pyrolysis device. Background technique [0002] With the development of economy and society, the amount of organic waste such as oil sludge, sludge, and domestic waste has increased sharply. Although these organic wastes have certain resource attributes, they contain a large amount of harmful substances. Efficient treatment and utilization of them are of great importance to the country. Sustainable development and environmental protection are of great significance. [0003] Pyrolysis heats organic waste under anaerobic conditions, decomposes its organic components by heat, and then condenses and pyrolyzes volatiles to obtain high-quality gas, solid or liquid products. It is an important organic waste with high efficiency. Approach. In the process of pyrolysis treatment of organic waste, it is an extr...

Problems solved by technology

For conventional solid or liquid organic waste, a conventional screw feeder or oil pump can be used for material transportation to achieve a better feeding effect. However, for waste such as oil sludge and sludge, generally accompanied by liquid phase, semi-slurry The coexistence of multiple phases such as solids and solids makes the treatment of waste more difficult, and it is extremely difficult to mix materials evenly. There is a lack of stable and efficient feeding methods, which seriously affects the stability and continuity of back-end treatment devices.
