Brief description of the drawings
Fig. 1 is illustrated that the life refuse processing method technical process figure that the present invention is implemented
Fig. 2 is illustrated that the life refuse processing method detailed process flow figure that the present invention is implemented
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Rubbish from cooking of the main component of house refuse based on organic matter, based on dirt, dust, glass and brick and tile etc.
Want the inorganic matter of composition, and plastics, rubber, paper and yarn fabric with higher thermal value etc., in addition also metal and other
Formed Deng debris.Ratio shared by the composition of house refuse with region difference, the difference of the level of economic development, town and country not
Same and various years change can all have significant change, but the main component of house refuse is all approximate.
Fig. 1 shows the life refuse processing method technical process figure of the present invention, and Fig. 2 shows the life of the present invention
Waste disposal method detailed process flow figure, shown referring to Figures 1 and 2, domestic rubbish disposal workflow is as follows：
When house refuse is transported to the garbage feeding at garbage disposal center by environmental sanitation department, house refuse is adopted first
The unpleasant peculiar smell of house refuse is removed with deodorization process, this maturation process flow is using a kind of toward sprinkling in house refuse
Deodorant liquid realizes, but this can also increase rubbish water content (house refuse itself will contain more moisture, especially simultaneously
It it is summer).At this moment stoving process processing is carried out to rubbish, moisture content is less than less than 80%, the energy required for stoving process
Using a part of internal combustion engine or the tail gas heat quantity of gas turbine.
After rubbish deodorization and drying is completed, refuse classification technique is subsequently entered, the heterogeneity in house refuse is entered
Row screening and classification.The equipment of sorting is to use comprehensive integrated separator, and this set sorting device is also mature technology at present, but
The careful degree of sorting has large effect to the number of investment.House refuse can be divided into oversize and screenings after having sorted.
Then oversize and screenings are handled respectively again.Future resident rubbish classified can reach reduce this ring
The workload of section, and the effect classified is more preferably more effective.
The main component of oversize has：The seldom thing of the calorific values such as metal, glass, battery, circuit board, brick, tile fragment and soil
Matter, although generally content is not high for these compositions, due to being the easy toxicant for producing pollution, it is therefore desirable to carry out
