Solid waste disposal process

Abstract

The invention discloses a solid waste disposal process for waste cloth and leather solid wastes primarily. The solid waste disposal process comprises the following steps: after pre-disposing the solidwaste in a dismantling stage and a screening stage, feeding the solid waste into crushing and forming stages, and feeding the solid waste uniformly into the forming stage when meeting forming conditions to prepare a particle fuel; and feeding the formed particle fuel into a pyrolysis and gasification stage, and purifying the generated fuel gas to product clean fuel gas, wherein the clean fuel gascan be used for gas power generation and gas heating, and power generation waste heat can be used in pre-heating disposal in a previous process course. The process route combines preparation of the particle fuel of waste cloth and leather solid wastes with a pyrolysis and gasification technique to generate the clean fuel gas for power generation and heating, so that proper disposal of the solid waste is achieved. The solid waste disposal process for the solid waste has the characteristics of being high in recovery rate, low in disposal cost and high in reducing degree, and has the advantage that an energy source can be utilized to the maximum extent by means of the generated particle fuel and clean gas.

Description

technical field [0001] The invention relates to a solid waste treatment process. Background technique [0002] With the rapid growth of urban population, the amount of domestic waste generated is also showing a trend of large volume and high growth rate. Among them, my country's textile industry consumes 35 million tons of cotton, hemp, chemical fiber and other textile fiber raw materials every year; at the same time, according to experts' calculations, the annual solid waste generated in the production process, such as textile scraps and household waste textiles, totals more than 2,000 tons. 10,000 tons, but only 5% of the textile waste has been properly recycled, and the rest have been landfilled as garbage. For waste leather, my country's tanning industry produces a large amount of waste hide and collagen materials every year. As a traditional industry with high input and low output, 30% of the raw materials in the leather industry eventually become solid waste in the pro...

Problems solved by technology

[0003] At present, the existing treatment methods for solid waste such as waste cloth and leather mainly include: incineration, landfill, composting, and production of chemical raw materials, etc.; such treatment methods have various disadvantages: waste of resources, generation of secondary pollution, disposal The cycle is too long, etc.
