Problems solved by technology

[0003] At present, the conventional barbecue charcoal production technology is mainly based on charcoal, but the disadvantages of serious environmental pollution, low yield, and high price of wood raw materials are common in the charcoal production process, resulting in high charcoal prices.
[0004] At present, some of the technologies that use coal-based charcoal to make barbecue charcoal mainly have defects such as difficulty in ignition, non-shedding of charcoal ash, and low heat utilization rate.

Embodiment 1

[0031] Embodiment 1: as figure 1 As shown, a lignite-based semi-coke clean barbecue charcoal preparation method contains the following steps:

[0032] Step a, preparing lignite semi-coke: crushing lignite to less than 80 mm, the crushed lignite is dried by dryer, pyrolysis reaction is carried out in pyrolysis furnace, and solid lignite semi-coke is produced, and lignite semi-coke is crushed Machine crushed to <3mm and sent to follow-up mixing;

[0033] Step b. Mixing: Stir and mix the solid semi-coke powder, binder, sulfur-fixing agent, etc. through the mixer, and send the mixed material and water into the wheel mill for rolling and secondary mixing to form a molding mixture ;

[0034] Step c, molding: transport the mixture to the molding machine through the conveyor, and make barbecue charcoal products of different shapes through the molding machine;

[0035] Step d, drying: transport the formed wet barbecue charcoal to a mesh belt dryer for drying;

[0036] Step e, packi...

Embodiment 2

[0044] Embodiment 2: as figure 1 As shown, a method for producing lignite-based semi-coke clean barbecue charcoal includes processes such as lignite crushing, drying, pyrolysis, semi-coke re-crushing, mixing, rolling, forming, and drying.

[0045] The invention has the processes of lignite crushing, drying, pyrolysis, semi-coke re-crushing, mixing, rolling, forming, and drying.

[0046] The lignite is crushed to less than 80mm, and the crushed lignite is dried by the dryer and pyrolyzed in the pyrolysis furnace to produce solid lignite semi-coke, which is then crushed to <3mm by the crusher and sent to the follow-up Mix and stir. The raw material used is lignite with high moisture content, high volatile content and low ignition point.

[0047] The solid semi-coke powder, binder, sulfur-fixing agent, etc. are stirred and mixed together by the mixer, and the mixed material and water are sent to the wheel mill for rolling and secondary mixing to form a molding mixture. Under t...

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. In order to meet the needs of people's barbecue activities, barbecue charcoal, which is indispensable for barbecue, has become a best-selling product in various stores and markets. [0003] At present, the conventional barbecue charcoal production technology is mainly based on charcoal, but the disadvantages of serious environmental pollution, low yield, and high price of wood raw materials generally exist in the charcoal production process, resulting in the high price of charcoal. [0004] At present, in the technology of partially adopting coal-based charcoal to make barbecue charcoal, there are mainly defects such as difficulty in ignition, non-shedding of charcoal ash, a...
