Embodiment Construction

[0013] The preparation method of the present invention is:

[0014] a, first crush the corn stalks with a hammer mill to reach 200 mesh;

[0015] b. Then mix the crushed corn stalks and rice husks at a ratio of 7:3, and then send them into a hammer mill to pulverize to 200 mesh;

[0016] c. Send the mixed material into the dryer and dry until the water content is below 8%;

[0017] d, the above steps are completed by the following device:

[0018] First, corn stalks and rice husks are sent into the pulverizer 2 according to the above ratio, and the pulverized materials are then sent to the material drying cylinder 7 through the pipeline 6. There is a heat channel 5 inside the material drying cylinder 7, and the front end of the heat energy channel 5 It communicates with the drying furnace 4, and the tail end extends out of the drying cylinder 7 to connect with the chimney, and a thermal energy blower 3 is installed at the front end of the material drying channel 7, and a the...

Abstract

A straw coal belongs to the field of energy. The purpose of the invention is to produce straw coal that meets the heat energy required for daily civil use by using corn stalks and rice husks after treatment. The preparation method of the present invention is as follows: first, crush corn stalks with a hammer mill to reach 200 mesh; then mix the crushed corn stalks with rice husks at a ratio of 7:3, and then send them to the hammer mill to crush to 200 mesh ; Send the mixed material into the dryer, and dry it until the water content is below 8%; send it into the straw coal forming machine, and the crushed and dried material is extruded by the screw propeller blade inside the straw coal forming machine, and the pressure is above 480MPa , and heated to 330 degrees at the outlet of the straw coal molding machine, the density of the extruded material reaches 1.2-1.4 tons / m 3 . The invention is a new type of biomass renewable energy, which is clean and environmentally friendly, and is far lower than the price and cost of raw coal, and has a wide range of applications. It is small in size, high in proportion, resistant to combustion, easy to store and transport, has the same quality as natural coal, has a promising market prospect, and is low in cost.

Description

technical field [0001] The invention belongs to the field of energy. Background technique [0002] According to the forecast of the International Renewable Energy Organization, the reserves of underground oil, natural gas and coal can only be used for about 60 years according to the current exploitation and utilization rate. Biomass energy has also emerged with the development of society, and straw is a waste material in rural areas, which is easy to obtain, and the great value contained in straw has not been utilized. With the world's energy shortage, the market demand for biomass renewable energy will be immeasurable. Contents of the invention [0003] The purpose of the invention is to produce straw coal that meets the heat energy required for daily civil use by using corn stalks and rice husks after treatment. [0004] The preparation method of the present invention is: [0005] a, first crush the corn stalks with a hammer mill to reach 200 mesh; [0006] b. Then m...
