Method for preparing biomass type coal adhesive from boghead coal and co-producing biomass type coal and organic fertilizer

Abstract

The invention discloses a method for preparing a biomass type coal adhesive from boghead coal and co-producing biomass type coal and an organic fertilizer, which comprises the following steps of: crushing boghead coal, adding alkaline liquor to boil, keeping the temperature, standing, and taking supernate as the biomass type coal adhesive; mixing corn straws, coal gangue with soft coal after crushing, adding the biomass type coal adhesive, solid sulphur and a waterproof agent, after uniformly mixing the biomass type coal adhesive, the solid sulphur and the waterproof agent with water, and extruding, forming and drying through a forming machine to obtain biomass type coal; and filtering biomass type coal adhesive preparation residues, adjusting pH, adding cow dung to ferment, and dosing, pelleting and drying to obtain the organic fertilizer. According to the invention, the abundant boghead coal resource in inner Mongolia is utilized for developing cheap adhesive; the biomass type coal, which has the advantages of being low in cost, high in sulphur content, moisture-proof and water-resistant and is applicable to an industrial furnace, is developed by utilizing abundant coal gangue resource and corn straw resource; and residues after preparing the biomass type coal adhesive from boghead coal are used for preparing the organic fertilizer, and therefore, the method disclosed by the invention is capable of saving energy, reducing emission, reducing the production cost of the biomass type coal, and increasing the additional value of boghead coal and the utilization rate of coal gangue.

Description

technical field

[0001] The invention relates to a method for preparing biomass briquette binder from peat to jointly produce biomass briquette and organic fertilizer, and belongs to the application field of clean and effective utilization of coal. Background technique

[0002] The pattern of my country's energy industry is "lack of oil, little gas, and rich coal". This resource endowment characteristic and my country's current industrial-based economic model determine the important position of coal in the industrial system. Due to the rapid development of China's economy, energy consumption has surged. In 2010, energy consumption accounted for 20.3% of the total global energy consumption, surpassing the United States to become the world's largest energy consumer, of which coal consumption accounted for 48.3% of the global total. Despite the rapid growth of new energy sources, coal is still the main energy source in China, which is difficult to change in the short term, causi...
