Embodiment Construction

[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0020] A comprehensive and environmentally friendly charcoal production process for waste crop straw resources, including the following process steps,

[0021] 1) Collect waste straw resources in agricultural production as main materials, such as corn straw, wheat straw, cotton straw, soybean straw, etc., and crush the straw to 80-100 mesh, so that the prepared charcoal has a higher combustion rate and heat energy achieve the best;

[0022] 2) Add a binder to the crushed straw powder, and also add some sawdust, bamboo powder, etc., and then put it into a stirring device for stirring, the purpose is to make the straw easy to form and facilitate subsequent processing needs;

[0023] 3) During the stirring process, it is necessary to heat the stirri...

Abstract

The invention relates to a comprehensive environment-friendly carbonizing technology by using waste crop straw resources. The technology comprises the steps of (1) collecting waste straw resources in agriculture production to be taken as a main material, and smashing the straw into 80-100 mesh; (2) adding a binder into the powder of the smashed straw, or adding some saw dust, bamboo powder and the like simultaneously, then putting into a stirrer to stir; (3) heating the stirrer while stirring, so as to better mix the powders, wherein the heating temperature is controlled at 50-60DEG C, and the heating time is 30-60minutes; (4) analyzing the water content of the mixed materials, and controlling the water content of the material at 15-20%; (5) sending the straw powder with qualified water content into a rod molding extruder for extrusion forming, wherein the heating temperature in the rod molding extruder is guaranteed to be not less than 200DEG C so as to obtain carbon rods of the specific size; and (6) naturally cooling down the obtained carbon rods to room temperature.

Description

Technical field: [0001] The invention relates to the technical field of resource reuse, in particular to a comprehensive and environmentally friendly charcoal production process from waste crop straw resources. Background technique: [0002] The use of straw as fuel is an urgent task to solve the outlet of straw at present. It can not only avoid the negative impact caused by straw burning, but also turn waste into treasure. However, due to the throwing and loosening of the stalks, it cannot be used as a normal fuel. Therefore, only the stalks can be used as fuel by pressing the stalks. [0003] First of all, the straw charcoal technology is becoming more and more mature in theory, but its practicability is poor. The straw charcoal content is low, the calorific value is low, the collection and transportation costs are high, the charcoal working environment is harsh, and the labor intensity is high. Not wide. Furthermore, straw gas production technology has been successfully...
