技术领域technical field

本发明涉及一种垃圾处理，尤其涉及一种生活垃圾资源化处理装置及其处理方法。The invention relates to garbage treatment, in particular to a domestic garbage resource treatment device and a treatment method thereof.

背景技术Background technique

迅速而巨量增长的城市生活垃圾给我国带来了严峻的社会、环境压力；同时，被誉之为“永不枯竭的矿藏”的城市生活垃圾的资源化、无害化综合利用，对于改善人民群众生活环境、减少资源浪费、发展循环经济，都具有十分重要的意义。要使城市垃圾综合利用目的得以实现，必须突破制约垃圾处理的瓶颈问题——垃圾分类技术这一世界难题。The rapid and huge growth of municipal solid waste has brought severe social and environmental pressure to our country; at the same time, the resourceful and harmless comprehensive utilization of municipal solid waste, which is known as the "inexhaustible mineral deposit", is of great importance to the improvement of People's living environment, reducing resource waste, and developing circular economy are all of great significance. In order to achieve the purpose of comprehensive utilization of urban waste, it is necessary to break through the bottleneck problem that restricts waste disposal - the world problem of waste sorting technology.

中国城乡生活垃圾高水分、低热值、混合收集的特点决定了西欧的生活垃圾处理技术与设备不可以全盘照搬至中国。建造和运营成本相对较高的生活垃圾焚烧技术只有应用在经济发达、人口集中、用地紧张的大城市，才具有一定的优势。随着国际间环境保护意识的不断提高，生活垃圾的综合利用已经成为了一种新的发展趋势。The characteristics of high moisture, low calorific value, and mixed collection of urban and rural domestic waste in China determine that the domestic waste treatment technology and equipment in Western Europe cannot be completely copied to China. Domestic waste incineration technology with relatively high construction and operating costs has certain advantages only if it is applied in large cities with developed economy, concentrated population, and tight land use. With the continuous improvement of international awareness of environmental protection, the comprehensive utilization of domestic waste has become a new development trend.

与国外相比，我国的生活垃圾具有自身的特性，由于我国垃圾分类收集普及率较低，大多生活垃圾都是混合原生垃圾，其次我国的生活垃圾有机物含量是发达国家的一倍左右，并且含水量较高。而且，我国生活垃圾一直处于混合收集。其中的弊端在于有利用价值可直接回收利用的物质如果直接处理了，不仅造成资源的浪费，还增加了垃圾处理量，增加了处理成本；混合收集中还含有一些危险废物如日光灯管、废旧电池等，不仅增加了无害化处理的难度，而且一旦处理不当就会造成严重污染。且我国居民垃圾管理还没有形成完整的体系，其中农村与乡镇生活垃圾还没有纳入环境卫生管理体系，无论是收集转运还是处理处置都没有相应的管理模式和管理体系，所以其处理处置不可能形成完整的产业。就全国范围来看我国生活仍处于混合收集的状态，大大增加了资源化、无害化处理的难度。同时我国生活垃圾的资源化处理还处于初步阶段，处理技术落后，收集处理设施不能适应发展的需要，环境卫生管理法规不健全。生活垃圾仍以卫生填埋和堆肥为主。其中卫生填埋约占79.2%，但符合标准的卫生填埋不足20%.，堆肥约占18.8%，焚烧处理约占2%。而且大多数中小城市仍未实现垃圾的资源化、无害化、减量化的科学处理，经济条件好的一些大城市虽然已建立生活垃圾处理厂，但由于资金和技术缺乏，运行状况却不是很理想。Compared with foreign countries, my country's domestic waste has its own characteristics. Due to the low popularity of waste classification and collection in my country, most of the domestic waste is mixed primary waste. Secondly, the organic matter content of domestic waste in my country is about twice that of developed countries, and contains The water volume is higher. Moreover, my country's domestic waste has been in mixed collection. The disadvantage is that if the materials with useful value can be directly recycled, if they are directly processed, it will not only cause a waste of resources, but also increase the amount of garbage disposal and increase the cost of disposal; mixed collection also contains some hazardous waste such as fluorescent tubes and used batteries. etc., which not only increases the difficulty of harmless treatment, but also causes serious pollution if it is not handled properly. Moreover, a complete system of resident waste management has not yet been formed in our country. The rural and township domestic waste has not yet been included in the environmental sanitation management system. There is no corresponding management model and management system for collection, transfer, and disposal, so its treatment and disposal cannot be formed. complete industry. As far as the whole country is concerned, life in our country is still in a state of mixed collection, which greatly increases the difficulty of recycling and harmless disposal. At the same time, the resource treatment of domestic waste in our country is still in the preliminary stage, the treatment technology is backward, the collection and treatment facilities cannot meet the needs of development, and the environmental sanitation management regulations are not perfect. Household waste is still dominated by sanitary landfill and compost. Among them, sanitary landfill accounts for about 79.2%, but less than 20% meet the standards. Composting accounts for about 18.8%, and incineration accounts for about 2%. Moreover, most small and medium-sized cities have not yet realized the scientific treatment of waste recycling, harmlessness, and reduction. Although some large cities with good economic conditions have established domestic waste treatment plants, due to lack of funds and technology, the operating conditions are not good. Ideal.

垃圾分选的设备投资和配套建筑设施的投资分别占到垃圾处理厂设备总投资和建筑设施总投资的40%左右，设备故障和能耗分别约占整个系统设备故障和能耗的一半。因此，寻找一种高效率、高精度、低成本、生态化的生活垃圾分选技术，正成为世界各国解决生活垃圾问题的一种迫切需要。The investment in waste sorting equipment and supporting building facilities accounted for about 40% of the total investment in waste treatment plant equipment and building facilities, and equipment failures and energy consumption accounted for about half of the total system equipment failures and energy consumption. Therefore, finding a high-efficiency, high-precision, low-cost, and ecological domestic waste sorting technology is becoming an urgent need for countries all over the world to solve the domestic waste problem.

Household garbage in the third-stage trommel 11-3 that is smaller than the mesh diameter of the third-stage trommel 11-3 falls onto the belt conveyor under the third-stage trommel, and domestic garbage that is larger than the mesh diameter of the third-stage trommel 11-3 falls on the belt conveyor under the third-stage trommel 11-3. The outlet of the first-stage trommel screen 11-3 is blown horizontally by a fan arranged on one side of the outlet, and falls into the heavy component collection tank 12, the medium and heavy component collection tank 13 and the light component collection tank 14 on the other side of the outlet respectively.

h.落入重组分收集槽内12的生活垃圾，经过人工分拣将生活垃圾中的有机物和填埋物分开，大块有机物送进破碎机挤成小块，然后送进发酵池17发酵，用作生物有机肥，填埋物送进填埋场，h. Household garbage falling into the heavy component collection tank 12, through manual sorting, the organic matter in the domestic waste is separated from the landfill, and the large piece of organic matter is sent into the crusher to be squeezed into small pieces, and then sent to the fermentation tank 17 for fermentation. Used as bio-organic fertilizer, the landfill is sent to the landfill,

i.落入轻质组分收集槽14内的生活垃圾进入旋风除尘器6，经旋风除尘器6内的旋流分离机分离出轻物、次轻物和较重物，在旋流的作用下颗粒灰尘等从上方排出，下方物质厨余等，进入手选皮带机8，i. Household garbage falling into the light component collection tank 14 enters the cyclone dust collector 6, and the cyclone separator in the cyclone dust collector 6 separates light objects, second light objects and heavier objects. The lower particles, dust, etc. are discharged from the top, and the bottom material, such as kitchen waste, enters the hand-selected belt conveyor 8,

j.在一级筛下皮带机的出料端设置涡流分选机5，垃圾被进一步分类成黑色金属以及其他垃圾，分别进入黑色金属收集槽15和其他垃圾收集槽16内，其他垃圾、中重组分收集槽13内的垃圾、一级筛下皮带机上的其他垃圾、三级筛下皮带机上的垃圾经破碎后和二级筛下皮带机上的垃圾均落入双层振动筛7，j. An eddy current sorter 5 is set at the discharge end of the belt conveyor under the primary screen, and the garbage is further classified into ferrous metal and other garbage, which enters the ferrous metal collection tank 15 and other garbage collection tank 16 respectively. The rubbish in the heavy component collection tank 13, other rubbish on the belt conveyor under the first-stage sieve, the rubbish on the belt conveyor under the third-stage sieve after being crushed, and the rubbish on the belt conveyor under the second-stage sieve all fall into the double-layer vibrating screen 7,
