Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the specific embodiments.

[0017] The inventor conducted experimental research from February 2007 to October 2009. The main contents of the research include:

[0018] 1. Effect of pure cow dung with different moisture content on coke compression effect

[0019] 2. The effect of different temperature and time on the carbonization effect of the finished product after compression

[0020] (1) Experimental design

[0021] The present invention adopts a single-factor random block test design and a two-factor random block test design. Single-factor randomized block experimental design: set 4 levels of water content, respectively 35%, 45%, 55%, 65%; two-factor randomized block experimental design: set 3 levels for temperature and time, respectively, temperature is 300 ℃, 450 ℃, 600 ℃, the time is 5h, 10h, 15h respectively, a total of 9 treatments.

Abstract

The invention discloses a method for preparing clean coke from cow dung, relating to the fields such as new energy resource exploitation, treatment of environmental pollution caused by animal husbandry, waste recycle and the like. The invention provides clean coke as a novel energy resource substance which has the advantages that the problem of environmental pollution caused by the cow raising industry (pig raising industry) is solved, the current resources are saved, and meanwhile, pollution to the environment cannot be caused after the clean coke burns. The clean coke is prepared by compressing pure cow dung subjected to dry and wet separation and then charring. According to the invention, the utilization limitation of cow dung resources by predecessors is broken through, the current situation of the scale of the cow raising industry in China can also be changed, raising cows in a concentrated way to the greatest extent can be realized, and a great number of clean energy resource substances are provided.

Description

technical field [0001] The invention belongs to the fields of coke production, animal husbandry environmental pollution control, waste recycling and the like. Background technique [0002] At present, the main raw materials for coke production are raw wood, wood chips, sawdust, straw, raw coal, etc., and binders, combustion accelerants and other substances need to be added in the production process; the use of these raw materials to make charcoal will undoubtedly increase the impact on forests. Deforestation causes damage to the ecological environment and intensifies the use of non-renewable resources. In recent years, with the rapid development of large-scale and intensive dairy farming, the problem of environmental pollution caused by the concentrated discharge of dairy manure has become increasingly prominent. There are more than 10 million cows, and the annual output of manure is about 120 million tons. Therefore, the treatment of cow manure has become a major problem i...
