In the solid waste compression device, many domestic manufacturers have developed a suitable for our national conditions of the garbage collection and compression station. Such as Shanghai Ruikang Environmental Protection Equipment Co., Ltd. developed a box station type garbage sorting, biochemical, collection as one of the three-in-one collection station, for the Shanghai municipal household garbage land and water collection and transportation supporting the use of; Shanghai Green Ring Machinery Co., Ltd. developed a micro-computer program-controlled SGC mobile household garbage compression and collection of machines, which set compression collection and garbage collection in one, and can realize a box of multi-machine operation. In general, these products incorporate machine, electricity, liquid integration technology, high degree of automation, small investment, high efficiency, no pollution and low cost of use, is very suitable for China's urban district garbage collection and transfer.
Shanghai Construction Road & Bridge Machinery Equipment Co., Ltd. showed its inorganic multi-purpose crusher, which is suitable for the crushing of solid materials such as municipal garbage, rubber tires, waste packaging materials (wood, cardboard, hard plastics), and withered and residual branches, etc., and the decomposed very fine particles can be utilized as recycled materials; its industrial and construction garbage crushing station on display can handle construction garbage such as waste steel reinforcement; in addition to the Horizontal spiral sedimentation solid-liquid separation equipment was displayed.?
For foreign exhibitors, Finland Baitec Cargo Handling Technology Co., Ltd. showed strong strength in solid waste collection and transfer equipment, the production of MULTILIFT (MULTILIFT) overall self-loading hydraulic hook (pull-arm truck) has entered the Chinese market, its good safety system, heavy loading and unloading capacity (up to 40t), high-quality high-strength wear-resistant steel, rapid operation has been praised by users. The operation of the production of black Yabo (HIAB) truck-mounted cranes compact structure, can be folded in the truck, light weight, full hydraulic power, the crane imitates the human arm movement without the use of wire ropes, in loading and unloading of goods in the safety of a good, high-precision, fast operating speed, and can be in the other types of cranes can not be reached at the dead end such as the back of the bridge for operation.
The Netherlands Environmental Protection and Disposal Group has launched a multi-functional garbage vertical compression transfer station system. The system relies on the self-weight of the garbage and top-down compaction to increase the density of the garbage in the compactor, thus saving energy consumption; only positioning mechanism between the compactor and the container, without the need for locking mechanism, when the container is full of garbage, the garbage is compressed leachate flow to the bottom of the container and will not flow to the outside of the container; the transfer station can be handled on a daily basis from dozens of tons to a few thousand tons, the investment and operating costs are relatively low. This technology has been successfully used in Europe, South America, Oceania and has entered the domestic market, such as Shanghai Chongming domestic waste transfer station used the system, the operating results are very good.
PetersonPacific developed the construction waste treatment equipment, its processing machine covers an area of small and the use of tracked structure, can be in the wheeled mill can not pass through the site to deal with the demolition of the building debris, grass and wood waste, construction debris, and even the logs of the milling work, and will not be like ordinary milling machine to occur in the waste support in the feed inlet of the phenomenon of clogging.
Shanghai Hanover Trade Development Co., Ltd (German agent) showed Hako push sweepers and driving vacuum sweepers. The hand-push sweeper is safe and dust-free, lightweight in operation, and convenient and effective in handling garbage and debris. Compared with the domestic sweeper, its driving vacuum sweeper structure is compact and flexible, the appearance is smooth and beautiful; the use of standard garbage cans, handling dumping garbage is extremely convenient; suction power, able to remove the road sand, iron and other metal garbage; its patented design of the hinge positioning steering is very suitable for turning flexibly on the narrow road.
From a general point of view, the domestic manufacturers of rear-mounted garbage compression collection vehicles, solid waste compression device development is more mature, while the road sweeper, cleaner, garbage transfer device and other gaps with foreign countries is more obvious.
2 biochemical treatment equipment
The essence of organic waste treatment technology is composting technology, composting technology is generally in the natural or artificial conditions, while organic waste treatment is in the composting before the artificial addition of specific micro-organisms in order to accelerate the decomposition of organic waste.?
The treatment technology has made great progress. Ltd. developed WBF microorganism organic waste treatment machine series products and BF strains, for the reduction of domestic waste, harmless, resource control and treatment provides a more effective and operable way; Shanghai Huaxia environmental protection and ecological science and technology Co., Ltd. developed the garbage resource ecological no residue treatment system (TBS), which is high-tech diversified means of rapid treatment of various types of waste, to achieve the goal of waste disposal. Ltd. developed a waste resource ecological residue-free treatment system (TBS), which is a high-tech diversified means of rapid treatment of various types of waste to achieve the reuse of residual materials; Japan Tian Xiong Co., Ltd. developed a dry biogasification system from the food scraps and other organic wastes in the refinement of fermentation energy, the implementation of resource recovery. Overall it seems that the current domestic waste biochemical treatment has been gradually industrialized.
3 incineration equipment?
Display of waste incineration equipment is mainly foreign companies, such as SEGHERS company's waste-to-energy technology is specifically designed for a variety of different types of waste research and development of different types of technology and devices after the 1970s, the device in the complete combustion of garbage, energy use, flue gas purification technology have reached the international advanced level. AMANASU has developed a plasma value-added furnace to realize the melting process by applying the principle that the *** vibration effect of ions and microwaves can increase the temperature and ion density, and the plasma furnace will hardly emit highly toxic substances such as dioxins and CO\-2 after treatment.
In general, it seems that these foreign waste incineration equipment after years of research and improvement, the level of high, complex technology and expensive equipment. Because of our country's garbage moisture, low calorific value, in many areas do not have the basic conditions of garbage incineration, although in several developed cities in the country is gradually approaching the level of the calorific value of garbage in developed countries, but whether the introduction of advanced incineration equipment from abroad is also worthy of serious consideration.
