Method for preparing biomass fuel from fresh cow dung

Abstract

The invention relates to a biomass material prepared by taking fresh cow dung as a raw material, which comprises the following components in parts by weight: 35-50 parts of fresh cow dung, 20-35 parts of dry coal powder, 8-15 parts of deodorizing adsorbent and 0-22 parts of loess, wherein the deodorizing adsorbent comprises the following components in parts by weight: 17-25 parts of bentonite, 6-13 parts of zeolite powder and 3-5 parts of potassium permanganate. The method for preparing biomass fuel from fresh cow dung comprises the following steps: (1) under the condition of continuous fine weather, collecting the fresh cow dung, and uniformly mixing for later use; (2) preparing raw coal, and pulverizing to uniform powder for later use; (3) preparing the deodorizing adsorbent: weighing a proper amount of bentonite, zeolite powder and potassium permanganate, and uniformly mixing for later use; and (4) proportionally weighing the treated fresh cow dung, the coal powder and the deodorizing adsorbent, uniformly mixing, and pressing to obtain the biomass fuel. According to the invention, the problem of coal resource constraint is solved to some extent, and the problem of environmental pollution caused by combustion of petrochemical energy is relieved. Thus, the method provided by the invention is of great practical meaning for popularization in vast rural areas and the like.

Description

technical field [0001] The invention belongs to the field of resources and environment, in particular to a preparation method of biomass fuel. Background technique [0002] Animal husbandry is an important part of the agricultural economy, and the proportion of annual output value in the agricultural field has increased year by year, approaching 50%. At present, the annual stock of dairy cows in China has exceeded 15 million, and the industrial development direction has entered the level of large-scale, intensive and professional barn feeding. With the continuous expansion of the scale of animal husbandry production and the continuous improvement of intensification, the pollution of livestock and poultry excrement to the environment has become increasingly serious and has become a new source of pollution. The lack of proper disposal of these livestock and poultry manure and other wastes will definitely damage the ecological environment, affect the safe production of livesto...
