1 Solid waste collection and transfer equipment?
In terms of solid waste compression devices, many domestic manufacturers have developed garbage collection and compression stations suitable for my country's national conditions. For example, Shanghai Ruikang Environmental Protection Equipment Co., Ltd. has developed a three-in-one collection station that integrates box-station garbage sorting, biochemical and collection, which is used to support the water and land container transport of domestic waste in Shanghai; Shanghai Green Ring Machinery Co., Ltd. has developed a microcomputer The program-controlled SGC mobile domestic garbage compression and collection machine integrates compression collection and garbage collection, and can realize multi-machine operation in one box. Generally speaking, these products integrate mechanical, electrical and hydraulic integrated technologies, have high degree of automation, small investment, high efficiency, no pollution and low use cost, and are very suitable for garbage collection and transfer in urban communities in my country. ?
Shanghai Jianshe Road and Bridge Machinery Equipment Co., Ltd. demonstrated its inorganic multi-purpose crusher, which is suitable for municipal waste such as rubber tires, waste packaging materials (wood, cardboard, hard plastics), dead branches and other solid materials During the crushing process of materials, the decomposed ultra-fine particles can be used as recycled materials; the industrial and construction waste crushing station displayed can process construction waste such as waste steel bars and concrete; in addition, the horizontal spiral sedimentation solid-liquid separation equipment is also displayed. ?
For foreign exhibitors, Finland's Betko Freight Handling Technology Co., Ltd. showed strong strength in solid waste collection and transfer equipment. It produced the MULTILIFT integrated self-loading and unloading hydraulic hook (pull Boom truck) has entered the Chinese market. Its good safety system, overweight loading and unloading capacity (up to 40t), high-quality high-strength wear-resistant steel, and fast operation have won unanimous praise from users; the HIAB produced by The truck-mounted crane has a compact structure and can be folded on the truck. It is light in weight and fully hydraulically powered. The crane imitates human arm movements without using wire ropes. It has good safety, high precision and fast operating speed when loading and unloading goods, and can be used on other types of cranes. Work on inaccessible blind spots such as the back of a bridge. ?
The Dutch Environmental Protection Processing Group has launched a multi-functional garbage vertical compression transfer station system. This system relies on the weight of the garbage and top-down compaction to increase the density of the garbage in the compactor, thereby saving energy consumption; there is only a positioning mechanism between the compactor and the container, and no locking mechanism is required. When the container is full After the garbage is compressed, the leachate water generated when the garbage is compressed flows to the bottom of the container instead of flowing out of the container; the daily processing scale of the transfer station can range from dozens to thousands of tons, and the investment and operating costs are relatively low. This technology has been successfully used in Europe, South America, and Oceania and has entered the domestic market. For example, Shanghai Chongming Domestic Waste Transfer Station has adopted this system, and the operating results are very good. ?
The construction waste treatment equipment developed by PetersonPacific Company has a small footprint and a crawler structure. It can process demolished building debris in places where wheel grinders cannot pass. It can grind vegetation waste, construction debris, and even logs without clogging the feed inlet like ordinary grinders. ?
Shanghai Hannover Trading Development Co., Ltd. (German agent) displayed the Hako push sweeper and ride-on vacuum sweeper. The hand push sweeper is safe, does not raise dust, is easy to operate, and can handle garbage and debris conveniently and effectively. Compared with domestic sweepers, its ride-on vacuum sweeper has a compact and flexible structure, a smooth and beautiful appearance; it uses a standard trash can, making it extremely convenient to handle dumped garbage; it has strong suction power and can remove metal waste such as sand and iron filings from the road; and The patented hinge positioning steering is suitable for flexible turning on narrow roads. ?
Overall, domestic manufacturers’ rear-mounted garbage compression collection trucks and solid garbage compression devices are relatively mature, while road sweepers, cleaning machines, garbage transfer devices, etc. are far behind those of foreign countries. ?
2 Biochemical treatment equipment
The essence of organic waste treatment technology is composting technology. Composting technology is generally under natural or artificial conditions, while organic waste treatment is done artificially before composting. Specific microorganisms are added to speed up the decomposition of organic waste. ?
This processing technology has made great progress.
Shanghai Baifu Biological Application Technology Co., Ltd. has developed a series of WBF microbial organic waste treatment products and BF strains, which provide a relatively effective and operable method for the reduction, harmlessness, and resource control and treatment of domestic waste. Path; Shanghai Huaxia Environmental Protection and Ecological Technology Co., Ltd. has developed a waste resource-based ecological waste-free treatment system (TBS), which uses high-tech diversified methods to quickly process various types of waste and realize the reuse of remaining materials; Japan Tiankuma Co., Ltd. The developed dry biogasification system can extract fermentation energy from organic waste such as food residues and implement resource recovery. Generally speaking, domestic waste biochemical treatment has gradually developed towards industrialization. ?
3 Incineration equipment?
It is mainly foreign companies that display waste incineration equipment. For example, the waste-to-energy technology of SEGHERS Company was specifically designed to research various types of waste after the 1970s. Different types of technologies and devices have been developed. The device has reached the international advanced level in terms of complete waste combustion, energy utilization, and flue gas purification technology. ?AMANASU? Technology Company has developed a plasma value-added furnace using the principle that the oscillation effect of ions and microwaves can increase temperature and ion density to realize the melting process. After the plasma furnace treatment, there will be almost no discharge of highly toxic substances such as dioxins. Substances and CO\-2. ?
In general, after years of research and improvement, these foreign waste incineration equipment are of high level, technically complex and expensive. Due to the high moisture content and low calorific value of waste in our country, the basic conditions for waste incineration are not yet available in many areas. Although the caloric value of waste in several developed domestic cities is gradually approaching the level of developed countries, it is still worthy of serious consideration whether to introduce advanced foreign incineration equipment. consider.
