Method for synthetizing solid fuel by mixing house refuse with fire coal

Abstract

The invention discloses a method for synthetizing solid fuel by mixing house refuse with fire coal, which comprises the following steps of: separating metal from recycled house refuse and then crushing; then stirring the crushed house refuse together with crushed fire coal and yellow clay powder; profiling in a rolling type molding press after evenly stirring; when 5 to 6cm of ball-shaped material is profiled, entering a dryer for drying; when the drying effect is completely reached, placing the dried ball-shaped material in a crocodile breaker and then breaking into 1 to 2cm of grain bulk material, thereby producing the solid fuel. The method has the advantage that the house refuse treatment is more perfect, and the prepared solid fuel has easy storage, no secondary pollution and simple preparation process, and the house refuse can be effectively utilized, thereby saving energy resources.

Description

Technical field: [0001] The invention relates to a method for treating municipal domestic waste, in particular to a method for synthesizing solid fuel by co-combusting coal with domestic waste and the secondary utilization of the solid fuel. Background technique: [0002] In the known technology of waste disposal, traditional direct incineration to generate heat is a relatively common way, but the direct combustion of waste plastics in domestic waste will inevitably produce a large amount of harmful gases such as dioxins, causing serious air pollution. Therefore, the traditional direct incineration garbage disposal method produces harmful gases such as dioxins, which is a major technical problem that is difficult to manage. There is landfill method again, and this method occupies a large area, and expense is higher, not only wastes a large amount of land resources, also does not solve environmental pollution problem completely; Harmful bacteria will produce secondary pollut...

Problems solved by technology

[0002] In the known technology of waste disposal, traditional direct incineration of heat generated power generation is a relatively common way, but the direct combustion of waste plastics in domestic waste will inevitably produce a large amount of harmful gases such as dioxins, which will seriously cause air pollution

Therefore, the traditional direct incineration garbage disposal method produces harmful gases such as dioxins, which is a major technical problem that is difficult to control.

There is landfill method again, and this method occupies a large area, and expense is higher, not only wastes a large amount of land resources, also does not solve environmental pollution problem completely; Harmful bacteria will produce secondary pollution if they are not properly treated. For example, there are many known technologies for sorting and processing domestic waste into solid fuels, which show that some sort out bricks, tiles, sand, glass fragments, and vegetable leaves. The components of low-calorie organic waste are all sorted out, some are utilized, and some are thrown away, which does not meet the needs of completely disposing of domestic waste. In addition, whether it is mechanical sorting or other methods of sorting, in a word , the more items are sorted out, the greater the cost

What's more noteworthy is that when the outdoor temperature is above 0°C, all domestic garbage contains perishable food. If it is not disposed of in time, it will become moldy, rotten, and smelly anytime and anywhere. It is not easy to park for too long, and it is not easy to multi-process link to dispose of household waste
