Preparation method of clean lignite-based semicoke barbeque charcoal

Abstract

The invention discloses a preparation method of clean lignite-based semicoke barbeque charcoal, and belongs to the technical field of barbeque charcoal preparation by lignite-based semicoke. The barbeque charcoal is prepared from the lignite-based semicoke, binder and water. Lignite is crushed below 80 mm by crushing, the crushed lignite is subjected to drying in a drying machine and a pyrolitic reaction in a pyrolizing furnace in sequence, the solid lignite semicoke is produced, and after being crushed below 3 mm by a crusher, the lignite semicoke is sent for subsequent blending and stirring; solid semicoke powder, the binder, sulfur fixing agent and the like are subjected to stirring and blending treatment through a blender, and a blended material and the water are sent into an edge mill for grinding and secondary blending for formed mixture preparation; the mixture is conveyed to a forming machine through a conveyor, and barbeque charcoal products in different shapes are prepared through the forming machine; the wet formed barbeque charcoal is conveyed to a mesh-belt dryer for drying treatment. According to the method, the lignite semicoke is adopted as a raw material, so that the ignition point and the production cost of the barbeque charcoal are effectively lowered, which are beneficial to use and popularization of the barbeque charcoal.

Description

technical field [0001] The invention relates to a method for preparing lignite-based semi-coke clean barbecue charcoal, belonging to the technical field of lignite-based semi-coke clean barbecue charcoal. Background technique [0002] Barbecue has become a new way of leisure and entertainment for people.
