Physical modeling of briquetting processes on the basis of the wastes of polydisperse coke particles and cryogels of a polyvinyl alcohol
The relevance of this research is caused by necessity, complexity, and expensiveness of a residual product recycling. Wastes of both polyvinyl coke particles and coal are one of the crucial sources of soil, water reservoir, and ground water contamination. Therefore, a competent approach is needed to recover such wastes. The main purpose of the research is to develop a simple method for recovery of the wastes of coke-chemical industry. The work is aimed to propose the fuel briquettes made from the coke particles structured by cryogels of a polyvinyl alcohol. During experimental study, the aqueous solutions of polyvinyl alcohol are used. Such solutions are non-Newtonian fluids, whose viscosity depends on the shear rate and is measured by rotational viscometer RheoStress 600 (Germany). Industrial producing of the briquettes is implemented using special manufacturing line that consists of a mixer, vibrating press, freezing chamber, dryer, and automated packer. In the framework of this research, the fuel briquettes have been manufactured from the coke particles structured by cryogels of polyvinyl alcohol. A physical modelling of the briquetting based on the wastes of polydisperse coke particles and cryogels of polyvinyl alcohol has been implemented. A laboratory research has been carried out, which allowed one to develop a special technology applied for recovery of the coke wastes. As a result of this study, the elastic and structural behavior of the briquettes has been tested. It has been revealed that the obtained briquettes are characterized by high energetic properties. Such briquettes are easily transported and stored. They can be used in small power engineering facilities, small businesses, and in domestic use.
