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

Embodiment 1

[0010] After the municipal solid waste enters the treatment plant, firstly, the waste parcel bags are broken open mechanically, and with manual sorting, the metal objects contained in the waste are mainly selected, which can be dehydrated according to the humidity of the waste, and then all the remaining waste is put into the shredder Carry out pulverization treatment, complete at one time, and pulverize into powder, reaching a fineness of 50-60 meshes. The garbage powder pulverized by this method can evenly mix all solid combustibles with high calorific value and low calorific value in domestic garbage, so that those non-combustible items such as bricks, tiles, sand and stones, glass fragments, etc. Play a certain role, it can act as a support when burning, and has a good ventilation effect, so that those combustibles can achieve 100% combustion; use the crushed garbage powder as a ratio of 1 ton, add 250 kg of general waste powder per ton of garbage powder Coal-fired (coal-f...

Embodiment 2

[0012] The method is basically the same as in Example 1, except that the general coal powder of 300 kilograms is added to every ton of garbage powder, and the yellow clay powder of 140 kilograms is added again.

[0013] In order to fully reuse the solid fuel after burning, a recovery agreement can be drawn up with the user unit to take back the burned waste furnace ash, then put the waste furnace ash into the pulverizer and pulverize it into powder, and then 1 ton Add 30% of No. 500 cement and 20% of lime powder to the furnace ash powder. After mixing evenly with a mixer, use an 80-100-ton hydraulic press to directly press these mixed furnace ash and slag materials into building materials. Materials - square bricks, etc., can be pressed according to demand. The purpose of this is to fix all the solid harmful substances contained in the burned waste slag in the square bricks, which completely solves the problem of harmful solids in the burned waste slag. can meet emission requi...

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...
