Technique for preparing consumer waste regenerated coal

Abstract

The invention relates to a technology for treating living garbage, in particular to a complete production process for changing the living garbage to garbage renewable coal products. The urban living garbage is firstly sent to a designated garbage place for collection; then coarse visible inert materials and iron and steel metals are removed through the scratch, the vibration selection and the magnetic selection pre-treatment, after that, a coarse breaker is used for carrying out the coarse breaking of the garbage till less than 50mm; the coarsely broken garbage is extruded and dehydrated, a deodorant, a bactericide and sulfur fixing and chloride fixing substances are added after the dehydration, the even mixing is carried out in a stirrer; then the high-temperature drying by a tunnel kiln is carried out, the fine breaking is carried out after the drying, the particle size of the garbage is controlled to be within 20 meshes at the stage, an ignition agent, a combustion improver, a preservative, a adhesive, and the like, are added after the fine breaking, the even mixing with the garbage particles after the fine breaking is carried out in the stirrer; finally the coal is prepared by extrusion forming, the shape and the dimension can be achieved in the pass design of a template.

Description

technical field [0001] The invention relates to a technology for domestic waste treatment, in particular to a production process for domestic waste recycled coal. Background technique [0002] my country's total population is 1.3 billion. With the great changes in urban development and economic transformation, according to authoritative statistics in 2007, the urban population reached 577 million, accounting for about 44.38% of the total population. For example, based on 1 kg of domestic waste per capita per day in cities and towns across the country, the total amount of domestic waste in the country is 577 million kg per day, or 577,000 tons, and 210.6 million tons per year. Therefore, since the 1980s, the distress of "garbage surrounding the city" has been plagued by the development of cities and towns. [0003] In the late 1980s, people analyzed the composition and calorific value of garbage, and found that most of the urban domestic garbage in most western developed cou...

Problems solved by technology

[0005] The purpose of the present invention is to provide a process flow for the production of recycled coal from domestic waste, which fundamentally solves the problem of urban domestic waste. At the same time, it also considers the treatment of industrial waste water treatment sludge and domestic waste to make it resourceful, energy efficient, and efficient. Harmless and industrialized
