Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the specific embodiments.

[0016] The inventor conducted experimental research in Changfu Dairy Group, Nanping City, Fujian Province from August 2006 to December 2009. The main contents of his research include:

[0017] 1. The influence of pure cow dung with different water content on the compression effect

[0018] 2. The influence of different temperatures and times on the drying effect of the compressed finished product

[0019] 3. The influence on the combustion effect without adding any combustion aid

[0020] (1) Experimental design

[0021] The present invention adopts a single-factor randomized block test design and a two-factor randomized block test design. Single-factor randomized block test design: water content is set to 4 levels, 40%, 50%, 60%, 70%; two-factor randomized block test design: temperature and time are set to 3 levels, temperature is 80% ℃, 90℃, 100℃, time respectively 1...

Abstract

The invention relates to an intensive large-scale dairy farm cattle manure compressed high-density fuel and a method thereof, belonging to the field of environmental pollution abatement in livestock husbandry, waste recycling, new energy development and the like. The invention solves the environmental pollution caused by cattle industry, and can provide a new energy source substance-cattle manure compressed fuel. The method for preparing the high-density compressed fuel comprises the following steps: compressing pure cattle manure subjected to dry-wet separation, and baking. The invention changes the way of predecessors for utilizing the cattle manure resources, can also change the actual state of the scale of cattle industry in China, can maximize the centralized breeding, and saves abundant land resources and human resources.

Description

Technical field [0001] The invention belongs to the fields of animal husbandry environmental pollution control, waste recycling and new energy development. Background technique [0002] With the rapid development of large-scale and intensified dairy farming, the environmental pollution caused by concentrated discharge of dairy cow manure has become increasingly prominent. At present, the number of dairy cows and beef cattle in my country (including improved dairy cows and large beef cattle farms) is about 10 million or more, and each cow produces 35Kg of manure per day, and the annual manure output is more than 120 million tons. Fertilizing crops with cow manure will acidify and harden the soil. If cow manure is fermented, it will be affected by climate change. Therefore, the treatment of cow manure has become a major problem in the world, which also restricts the large-scale development of dairy cows. The invention aims to compress cow dung into high-density fuel to realize harm...
