Feeding and slag tapping method in processing of thermal decomposition of organic wastes

Abstract

The invention relates to a method for material charging and slag discharging during the pyrolysis treatment of organic waste. Crushing treatment which is adopted in the prior art has high investment, high energy consumption and difficult maintenance. The method is realized through the mode of water sealing. The method comprises the following steps: during the material charging process, strip and blocky organic waste is sent into a material charging water tank, the organic waste goes down onto a conveying device on the bottom of the material charging water tank through the self gravity of the waste and is conveyed from an inlet of a charging passage to an outlet of the charging passage by the conveying device, and enters a feed port of a pyrolysis device; and during the slag discharging process, the strip and blocky slag produced by pyrolysis directly drops into a slag discharging water tank arranged below a slag discharging port through the slag discharging port. The method does not crush the material to be pyrolyzed, has a remarkable energy-saving effect, lower manufacturing cost of the device, and improves efficiency of the recycling synthesis treatment of the organic waste.

Description

technical field [0001] The invention belongs to the technical field of organic matter treatment, and in particular relates to a method for feeding and discharging slag during pyrolysis treatment of organic waste. Background technique [0002] The disposal of organic waste should be based on the principles of recycling, reduction, and harmlessness. The pyrolysis process for organic waste has the characteristics of low secondary pollution, and can produce high-grade products such as oil, carbon residue and gas, and is currently generally favored by the industry. There are many pyrolysis processes of organic matter with industrial significance, which can be divided into dry distillation, thermal decomposition, thermal dealkylation, etc. according to the specific process. The pyrolysis process of hydrocarbons is often divided into thermal cracking and cracking. The temperature of the former is usually less than 600°C, and its purpose is to produce light oil from heavy oil, and...
