Abstract
The invention discloses a waste disposal method. The existing waste disposal process effect is poor, the overall utilization rate of waste is low, and the operating cost is high. The waste disposal method comprises the following steps: transporting waste to the selection process to be classified and selected and divided into domestic waste, industrial waste and plastic waste; dividing the plastic waste into hard plastic waste, soft plastic waste and foam plastic waste, and dividing the domestic waste into inorganic domestic waste and organic domestic waste; mixing the industrial waste and the organic domestic waste to be made into fuel; allowing the inorganic domestic waste to be made into inorganic fertilizers; and respectively allowing the hard plastic waste, the soft plastic waste and the foam plastic waste to be made into plastic raw materials. The invention has low operating cost, high utilization rate of waste, and no smoke and gas in the disposal process, and prevents the secondary pollution on the environment.
Description
Technical field
The invention belongs to field of treatment of solid waste, the method for the composting of categorised collection is not pressed in specifically a kind of processing.
Background technology
Along with the enhancing of global environmental protection consciousness, the garbage disposal of China has been passed through from the evolution of exposed rubbish → simple and easy landfill → simple and easy compost → During High-Temperature Composting → sanitary landfills and burning → recycling treatment.The unexecuted categorised collection of the rubbish of China, external technology of garbage disposal and equipment are not suitable for handling the rubbish of China because the characteristics of spam of its processing is different from domesticly.The every technology of garbage disposal that adopts in China as building landfill yard, dung yard or incineration plant, all can cause secondary pollution at present, and adopt burning electricity generation because the calorific value of garbage raw material is not high, can not the direct generation of electricity, and the voltage instability of generating, investment is big, and real industrialization operation difficult degree is big.
Summary of the invention
Technical problem to be solved by this invention is the defective that overcomes above-mentioned prior art, and a kind of method of the disposal of refuse of classifying is provided, and it makes full use of all kinds of rubbish, and it is turned waste into wealth, to avoid that environment is produced secondary pollution.
For this reason, the present invention adopts following technical scheme: a kind of waste disposal method, and its step is as follows:
1) rubbish is delivered to selects operation, rubbish classified select, be divided into house refuse, industrial refuse and plastic garbage three classes, and then plastic garbage is divided into duroplasts rubbish, soft plastic waste and foam plastic waste, house refuse is divided into inorganic house refuse and organic domestic waste;
2) industrial refuse and organic domestic waste mix, and obtain Powdered rubbish through packing process, freezing pulverizing process and heating process successively afterwards, and adding coal and combustion adjuvant mix in Powdered rubbish then, make fuel;
3) inorganic house refuse is passed through packing process, freezing pulverizing process and heating process (removal moisture) successively, makes inorganic fertilizer;
4) duroplasts rubbish, soft plastic waste and foam plastic waste are passed through successively matting (removing the rubbish on surface), packing process (breaking into parcel), freezing pulverizing process and heating process (removal moisture) respectively, enter packaging process at last, duroplasts, flexible plastic and foamed plastics powder to aforementioned operation gained are packed separately, can directly use as plastic raw materials.
The present invention is earlier with refuse classification, then utilize packing process to make rubbish break into a parcel, conveniently carry out subsequent processing (freezing process), the convenient pulverizing in the freezing back of rubbish, almost can make all rubbish all be Powdered, the efficient height, the carrying out of pulverous convenient garbage back operation and operation, overall utilization rate height.Most organic domestic wastes has the composition of burning, and most inorganic house refuses does not have the composition of burning, so both are separated, inorganic house refuse is directly made inorganic fertilizer.
Above-mentioned waste disposal method, the temperature of freezing processing are subzero 50-250 ℃, and the requirement of pulverizing is the 25-50 order, and the temperature of heating process is 80-100 ℃.
Above-mentioned waste disposal method, the quality percentage composition of each component in the fuel is: powdery rubbish 80-90%, coal 5-15%, combustion adjuvant 1-5%, described combustion adjuvant is selected commercially available combustion-supporting agent for fuel coal product for use, also can select other similar combustion adjuvant products for use, the fuel of making can directly use as the energy.
Advantage of the present invention is as follows: 1) utilize the freezing efficient of pulverizing, the Powdered rubbish that obtains after the pulverizing, the overall utilization rate height of having improved; 3) according to the characteristics of material, plastic garbage is divided into duroplasts rubbish, soft plastic waste and foam plastic waste, this three group is dealt with separately respectively, the product that obtains can directly use as plastic raw materials, house refuse is divided into inorganic house refuse and organic domestic waste, makes inorganic fertilizer and fuel respectively, turn waste into wealth, smokeless no gas in the garbage disposal process has been avoided environment is produced secondary pollution.
The invention will be further described below in conjunction with the specific embodiment.
The specific embodiment
The concrete steps of waste disposal method of the present invention are as follows:
1) rubbish is delivered to selects operation, rubbish classified select, be divided into house refuse, industrial refuse and plastic garbage three major types earlier, and then plastic garbage is divided into duroplasts rubbish, soft plastic waste and foam plastic waste three groups, house refuse is divided into inorganic house refuse and organic domestic waste two groups;
2) front is divided good industrial refuse and organic domestic waste mix, mixture breaks into parcel (25-50kg) by packing process earlier afterwards, then freezing at subzero 50-250 ℃, cooling time is 1-5 hour, cryogenic temperature and time are selected according to the size of packing, directly pulverize after freezing and obtain Powdered rubbish, the granular size of rubbish is the 25-50 order, by heating process Powdered rubbish is heated then, temperature is 80-100 ℃, and the time is 1-2 hour, the moisture in the evaporation rubbish, at last adding coal and combustion adjuvant in the Powdered rubbish are mixed (powdery rubbish 80-90%, coal 5-15%, combustion adjuvant 1-5%), make fuel;
3) inorganic house refuse is passed through packing process (breaking into parcel), freezing pulverizing process and heating process successively, the parameter area of freezing, pulverizing and heating process and the 2nd step identical (selecting corresponding condition), directly inorganic house refuse is made inorganic fertilizer according to actual conditions;
4) duroplasts rubbish, soft plastic waste and foam plastic waste are respectively hung oneself matting (removing surperficial non-plastic garbage), packing process (breaking into parcel), freezing pulverizing process and heating process, the parameter area of freezing, pulverizing and heating process and the 2nd step identical (selecting corresponding condition) according to actual conditions, make duroplasts, flexible plastic and foamed plastics powder respectively, enter packaging process at last, duroplasts, flexible plastic and foamed plastics powder to aforementioned operation gained are packed separately, can be used as plastic raw materials and directly use.
