I've compiled some relevant information for you:
The garbage pneumatic conveying system is a modern solid waste collection and transportation system, which makes use of an extractor fan to create an airflow, and through a network of vacuum pipes buried underground, transports garbage put in at various garbage drop-off points to the collection station, where it is separated from gas and solids, and then goes through a series of treatments, such as compression, filtration, purification, and deodorization, and is finally transported to the garbage The garbage is finally transported to the garbage treatment plant. During the whole process, the garbage is in a completely closed state, which hardly causes any pollution to the environment. In Finland, Norway, Japan and other developed countries, garbage pneumatic conveying system has been widely used, so that the city becomes cleaner.
At present, there are few places where this technology is used domestically, and the investment is very large, so it is difficult to operate this project without the support of the government.
The waste pneumatic conveying system has a wide range of application prospects. If this system is built in the community, residents do not have to go out to dump the garbage, the community's garbage cans, sanitation trucks will disappear, the residents just put a good class of garbage into the home of the mouth, the garbage will be sucked into the collection station.
The features are as follows:
1. Elegant folding environment
Pneumatic pipeline conveying system garbage completely sealed collection and transportation, can make the whole area environment can be effectively improved. The area can cancel the traditional collection tools and facilities such as handcart, garbage can, dumpster room, etc., which effectively reduces the secondary pollution. The system can basically avoid rickshaws and other means of transportation of garbage through the residential area, which is conducive to maintaining a clean and hygienic living environment.
2, folding the timely removal
For places and periods of high traffic flow, such as during the World Expo, the transportation hub area, the amount of garbage generated, such as not timely removal will cause garbage overflow, seriously affecting the overall image and use. The pneumatic pipe conveying system can adjust the cleaning frequency in time to avoid garbage overflow through the sensing equipment located at the drop-off port to show the garbage storage condition.
3. Smaller collapsed area
Pneumatic pipeline conveying system has high efficiency and high site utilization rate. The collection pipeline in the building is set in the pipeline trench, and the garbage transportation pipeline is set underground, which can effectively reduce the footprint of the garbage box room and so on.
4, less folding traffic
Pneumatic pipeline conveying system through the pipeline will be transported to the collection center of the garbage, reducing the garbage trucks in the district, can effectively reduce the collection of vehicles on the residents of the district to reduce the impact of air pollution, reduce noise.
5. Improvement of folding conditions
The pneumatic pipeline conveying system operates fully automatically, which significantly reduces the labor intensity of garbage collection, improves the collection efficiency, and optimizes the labor environment for sanitation workers.
6, folding system flexibility
Pneumatic pipeline conveying system has a variety of system forms, can flexibly respond to different functional requirements. The garbage drop-off port is located at the location near the user, which is convenient for drop-off. The garbage collection process is completed in the airtight pipeline and collection center, which is not affected by any weather. The entire system operates automatically, with high reliability and can work around the clock.
Compared with the traditional way of garbage collection, the garbage pneumatic pipeline conveying system is an efficient and hygienic method of garbage collection, but it also has the disadvantages of large one-time investment and high requirements for the maintenance and management of the system:
(1)Compared with the traditional way of garbage collection, the garbage of the pneumatic pipeline conveying system can be closed and automatically transported
(2)Since the Pneumatic pipeline conveying system adopts computer program to control the garbage collection process, the degree of automation is high, accordingly, the management personnel are required to have high management quality, and at the same time, the puter's putting behavior should be guided and regulated.
(3) The system requires regular inspections, repairs and maintenance by trained technicians to ensure that the components and equipment are in good condition and operate properly.
Example

Hammabe builds circular ecosystem
Hammabe Marina New Town in Sweden, in the morning and evening, there will be a faint buzzing sound from the ground, similar to the sound of a range hood at work.
In fact, it's the automatic garbage collection system underneath Hammabe at work. You can think of the system as a combination of underground pipes and a giant vacuum cleaner, and the garbage runs through this special "sewer" at 70 kilometers per hour to the garbage collection station at the edge of the neighborhood, a speed comparable to that of the subway.
In Hammabe, the garbage is divided into three categories, namely "organic waste", "combustible waste" and "paper", which makes the post-processing of the garbage very efficient. The three types of garbage are divided into three categories: organic garbage, burnable garbage, and paper. Each of the three types of garbage has its own destination. Combustible garbage is thrown into the incinerator of the local thermal power plant, where part of the energy generated by combustion is converted into electricity, and the other part of the heat energy is absorbed by the water flow and follows the "heating pipes" into the homes of the residents of the district to give play to the residual heat. Organic waste is sent to the biogas digester, which produces methane gas, part of which goes into the kitchens of the residents, and part of which is supplied to the hybrid cars in the neighborhood. The remaining residues are returned to the land as organic fertilizer. Waste paper goes to a recycling plant, where it is made into other paper products for further use.
As an important part of Hammabe's "recycling ecosystem," the automated garbage collection system, together with the sewage treatment system, biogas digester, centralized heating/cooling system, passive energy-saving buildings, use of solar energy, and "carpooling group" (more than 300 people) *** use 25 cars. *** Use of 25 cars) and other environmentally friendly and energy-saving technologies make the houses in Hanmabe in short supply even when the price of a house reaches about 90,000 Swedish kronor per square meter (equivalent to about 67,500 yuan), which is more than three times as much as in the surrounding areas.
This information is a real case, is a good municipal project, because of the high cost of construction, investment costs, now it is difficult to promote in the whole of Beijing and even the country, at present, only Changping's future science and technology city and Tongzhou core area has such a supporting the construction of the late living in such an environment is very clean and cozy.
