Method for preparing coal-based regeneration carbon

Abstract

The invention discloses a method for preparing coal-based regeneration carbon. The method includes particular manufacturing technological steps of a, selecting coal as a material, and manually or mechanically smashing the screened coal to allow the size of the material to reach 80-100 meshes by means of smashing; b, dewatering and drying the smashed raw material optionally by means of natural drying or heating drying to allow the water content of the smashed raw material to be lower than 10%; c, extruding the dried raw material, to be more specific, loading the material into an regeneration carbon molding machine, and extruding the material under the pressures of 60 megapascal at the temperatures of 100-140 DEG C under the control to obtain rod-shaped materials; d, carrying out smoke removal carbonization on the rod-shaped materials, to be more specific, loading molded rods into a carbonization furnace and carbonizing the molded rods for the carbonization time of 6-10 hours; e, coolingcarbonized regeneration carbon until the temperature of the carbonized regeneration carbon is lower than 50 DEG C so as to completely process the carbonized regeneration carbon. The method has the advantages that the coal is used as the raw material, accordingly, waste gas emission in processing procedures can be prevented, the temperatures can be quickly and effectively reduced, the quality of the regeneration carbon can be guaranteed, and the integral method is simple and scientific and is worthy of being popularized.

Description

technical field [0001] The invention relates to the technical field of machine-made charcoal processing, in particular to a method for preparing coal-based machine-made charcoal. Background technique [0002] Most of the machine-made charcoal is dried into standard raw materials with appropriate dry humidity through a drying furnace. After cooling, it enters the forming machine (rod making machine), and then is plasticized at high temperature and high pressure to form a fuel rod (semi-finished product). There are various forms of furnaces, generally brick-earth kiln) carbonized into finished machine-made charcoal. [0003] Machine-made charcoal includes low-temperature charcoal, medium-temperature charcoal and high-temperature charcoal. Low-temperature charcoal has a loose texture, low carbon content, and poor mechanical strength. Heating and hot pot, etc.; medium-temperature charcoal barbecue charcoal, its texture is tighter than low-temperature charcoal, and the carbon co...

Problems solved by technology

[0004] The main features of machine-made charcoal: high density, high calorific value, smokeless, odorless, non-polluting, non-explosive, flammable, is an internationally recognized green product, traditionally called most machine-made charcoal, choose rice husk, peanut husk, cotton husk , corn cobs, corn stalks, sorghum stalks, etc. are all used as raw materials, and a lot of waste gas will be generated during the processing, including CO, C0 2 ,H 2 , SO 2 etc., the production method is not environmentally friendly, in view of these problems, here we propose a coal-based machine-made carbon preparation method
