The invention specifically relates to a novel counterflow burning type coal gasifier device and a process thereof. The device is composed of following nine major systems: a coal charging system, a dry distillation system, a counterflow burning heating system, a combustion supporting air supply system, a steam supply system, a gas generation system, an ash removal system, an automatic temperature control system and a gas cooling purification system; the process comprises the following steps: 1) generating upper section gas containing dry distillation gas, tar gas, phenol organic matter gasses and water steam; 2) feeding the upper section gas into a combustion chamber for combustion through a hot gas supercharger; 3) introducing high temperature gas generated after combustion in the combustion chamber and containing water vapor and CO2 into the hearth at the lower section of the coal gasifier to contact with coke, and generating to generate lower section gas; 4) cooling and separating dust from the generated lower section gas and then transmitting the gas to the user end. The device and the process provided by the invention are free of discharge of pollutants such as tar and carbolisata aqua, and have the advantages of high heat utilization rate, energy conservation and environmental friendliness; the generated gas is high in cleanness and combustion value.

The invention discloses a water-soluble briquette adhesive and a process applied to briquette production thereof and relates to an adhesive for briquette for production industry and civilian use and application thereof. The water-soluble briquette adhesive is combined by organic water-soluble adhesive, inorganic water-soluble adhesive, water-soluble preservative, water-soluble combustion improverand water-soluble sulfur and fluorine removal agent, and the process flow for producing the briquette by utilizing the adhesive is as follows: A. raw material crushing; B. quantitative feeding; C. mixing and stirring; D. pinching and stirring; E. homogenizing; F. molding; and G. drying. The adhesive has little use amount in the briquette production, high adhesive strength, high content of fixed carbon and high fuel value, fire-leading is easy, the firepower is large, and soot smell is difficult to smell.

The invention belongs to the technical field of environmental protection, and particularly relates to a method for preparing a biomass fuel mainly from fresh chicken manure. The method comprises the following steps: 1) pretreating raw materials; 2) fermentation: mixing fresh chicken manure, mushroom sticks and calcined shell powder, inoculating deodorizing composite microbes and nitrogen fixation-desulfurization composite microbes, and carrying out pile fermentation; 3) naturally drying the fermentation material; and 4) adding tea stems, and carrying out extrusion granulation. The fresh chicken manure is used as the main raw material, the waste mushroom sticks, calcined shell powder and tea stems are used as the auxiliary raw materials, the deodorizing composite microbes and nitrogen fixation-desulfurization composite microbes are added, and the flammability and comprehensive combustion characteristics of the reinforcing material of the composite microbes are fully utilized, thereby preparing the biomass granular fuel which has the advantages of low ignition point, high combustion heat value and high combustion rate. The method can greatly consume chicken manure, and solves the problem of environmental pollution caused by chicken manure. The method provides direction for the recycling of the waste mushroom sticks, shells and tea stems.

The invention discloses a honeycomb briquette prepared by using fermented cow dung and a preparation method thereof. The honeycomb briquette comprises 20wt%-50wt% of maturely fermented cow dung and 50wt%-80wt% of pulverized coal. The preparation method of the honeycomb briquette comprises the following steps of (1) adding a certain amount of fermentative bacteria and rice hull powder to the cow dung so as to ferment the cow dung into the maturely fermented cow dung; and (2) fixing and forming, namely mixing the maturely fermented cow dung with the pulverized coal, crushing, stirring and mixing uniformly, selectively adding water during uniform mixing, and carrying out compression molding. The brand-new honeycomb briquette prepared by mixing the fermented cow dung and the pulverized coal, provided by the invention, is odorless and has high acceptability; smashed grasses or straws do not need to be additionally added to the honeycomb briquette, so that the cost is saved, and the honeycomb briquette is easy to form; and the preparation time of the honeycomb briquette is short, and the preparation process is simple, so that the honeycomb briquette is easy to popularize. The preparation method has the advantages that (1) the pollution problem of cattle farms can be greatly reduced; (2) the shortage of fuels can be solved; and (3) the utilization model of energy sources is explored.
