Cow dung fuel block and preparation method thereof

Abstract

The invention discloses a cow dung fuel block and a preparation method thereof, relating to a fuel block and a preparation method thereof. The invention solves the problems that low-temperature environment is not favorable for cow dung to ferment, and the prepared cow dung fuel brick has the problems of high moisture content in the cow dung and the need of adding broken grass or straws. the cow dung fuel block is prepared from half-dry cow dung, potassium nitrate, potassium permanganate and sodium chloride. The preparation method comprises: 1. weighing raw materials; 2. evenly stirring; 3. preparing honeycomb briquette. The invention adopts the half-dry cow dung to solve the problem that the cow dung serving as the fuel block needs to be thoroughly dried, so that the invention saves areas, does not produce mosquitoes and flies and saves energy. The cow dung fuel block of the invention can be shaped without broken grass and straws, has the characteristics of high strength and high fuel value and is not affected by seasons and temperature.

Description

technical field [0001] The invention relates to a fuel block and a preparation method thereof. Background technique [0002] my country is the largest producer of animal husbandry in the world, and it is also one of the countries with the largest number of cattle (dairy cows, beef cattle, cattle, buffaloes, and yaks). The development of animal husbandry has gradually developed from small-scale to intensive and urbanized breeding areas. With the adjustment of industrial structure, animal husbandry production has gradually separated from the agricultural production system, and the characteristics of independence and specialization have become more and more obvious. The large-scale and intensive farms and the increasing number of breeding areas have caused a sharp increase in the discharge of cattle manure and sewage, and the problem of breeding pollution has become more and more prominent, causing environmental pollution, which has become second only to industrial pollution. ...
