A portable solid waste classification and screening device

technical field

The utility model belongs to the field of environmental protection engineering equipment, in particular to a portable solid waste classification and screening device.

Background technique

With the rapid development of economy and society, the rapid improvement of urbanization level, the increasing scale of cities, and the increasing income and consumption level of residents, the generation of urban domestic waste in my country is also increasing. According to statistics, the number of cities in my country has increased from 193 in 1978 to 660 in 2003, and the urban population has increased from 172.45 million to 520 million; the urbanization rate has increased from 28% in 1993 to 40.5% in 2003 . At the same time, in 2003, the volume of domestic waste removal in my country reached 148.57 million tons, an increase of 8.8% over 2002; in addition, there are more than 2,300 counties in my country, the amount of domestic waste has not been counted, and it is estimated that the annual output is 0.4- 50 million tons. In recent years, the growth rate of garbage has reached 5-8%. The accumulation of garbage in cities has reached 6.6 billion tons over the years, occupying more than 3.5 billion square meters of land. Many cities have to extend the way to solve the garbage crisis to the countryside. Secondary pollution will lead to the deterioration of the ecological environment in the urban-rural zone.

At the same time, with the extensive use of polymer synthetic materials, various printed materials, plastic products, and packaging materials of various materials, the composition of municipal solid waste has undergone great changes and has become more and more complex. Taking Shanghai as an example, from 1990 to 2003, plastic waste rose from 4.0% to 13.33%, paper waste rose from 4.0% to 9.23%, fruit waste rose from 10.8% to 14.08%, and kitchen waste dropped from 71.9%. to 51.82%.

At present, among the huge amount of domestic waste in our country, most of them are not classified and collected, but mixed collection is the main method; in terms of treatment methods, most of them are landfill, supplemented by other treatments such as incineration and composting Methods, specifically: sanitary landfill of domestic waste accounts for 89.3% of the total treatment, composting treatment accounts for 6.98%, and incineration treatment accounts for 3.72%. Mixed collection of domestic waste into the landfill will cause loss and waste of resources, and the presence of plastics, metals, glass, chemical fibers and other substances will also have an adverse effect on the degradation of domestic waste. Domestic waste composting is suitable for degradable organic matter in domestic waste, but the mixed collection of waste hinders the development of domestic waste composting in my country. The plastic, metal, glass, chemical fiber and other substances in the waste will affect the microorganisms in the waste. The biodegradation of degradable organic matter makes the quality of compost very poor, which makes it more difficult to sell the compost which has a very narrow market; the domestic waste incineration method can obtain heat energy by burning waste, which can be converted into electric energy, but due to the low level of economic development in our country balance, the calorific value of domestic waste is generally low, and the current incineration method is only adopted by a few cities with developed economies and relatively high calorific value of domestic waste; moreover, the mixed collected domestic waste has a high moisture content and contains metal, glass, slag, etc. Substances such as soil have a relatively low calorific value, so domestic waste is more difficult to incinerate.

From the perspective of resource recycling, there are many substances in domestic waste, such as plastic, glass, metal, chemical fiber, paper, etc., which are renewable or reusable resources, which can be recycled after classification and sorting. sustainable development".

At present, my country advocates the source classification of domestic waste, which can fundamentally promote the "reduction, harmlessness, and resource utilization" of urban domestic waste. However, it is very difficult to implement this method due to the imperfect laws and regulations and the general low awareness of residents. Therefore, in order to implement the comprehensive treatment of "reduction, harmlessness, and recycling" of urban domestic waste in our country, it is necessary to carry out pretreatment of waste, that is, sorting before waste treatment. Therefore, perfect and reliable pre-sorting technology for domestic waste It is the key to improve the efficiency of garbage reuse and realize the comprehensive treatment process.

The research results show that the development of domestic waste separation equipment has made great achievements, but the main problem is that the key technology level is poor, and it is difficult to realize large-scale industrial production; the development often relies on experience, and there is no sufficient understanding of the separation process technology and separation effect; investment , Insufficient operating funds, incomplete supporting production system and other problems still exist, which are urgent problems to be solved in the whole production and engineering research.
