Garbage pneumatic conveying system is a modern solid waste collection and transportation system. It uses the exhaust fan to create airflow, and through the underground vacuum pipe network, it transports the garbage put into various garbage outlets to the collection station, where it is subjected to gas-solid separation, then compressed, filtered, purified and deodorized, and finally transported to the garbage treatment plant. In the whole process, the garbage is completely sealed, which will hardly cause any pollution to the environment. In Finland, Norway, Japan and other developed countries, garbage pneumatic conveying system has been widely used to clean cities.

At present, there are few places where this technology is used in China, and the investment is very large. Without the support of the government, this project is difficult to operate.

The garbage pneumatic conveying system has a broad application prospect. If this system is built in the community, residents will not have to go out to take out the garbage, and the garbage bins and sanitation vehicles in the community will be gone. As long as residents put the sorted garbage into their homes, the garbage will be sucked into the collection station. ?

Its characteristics are as follows:

1, elegant folding environment

The complete closed collection and transportation of garbage by pneumatic pipeline transportation system can effectively improve the environment of the whole area. Traditional collection tools and facilities such as trolleys, garbage bins and garbage bins can be cancelled in the area, effectively reducing secondary pollution. The system can basically prevent garbage transport vehicles such as rickshaws from passing through residential areas, which is conducive to keeping the living environment clean and hygienic.

2. Fold the pickup truck in time

For places and time periods with a large flow of people, such as during the World Expo and transportation hub areas, a large amount of garbage will be generated. If it is not cleared in time, it will cause garbage overflow and seriously affect the overall image and use. The pneumatic pipeline conveying system can display the storage state of garbage through the induction equipment arranged at the conveying port, adjust the cleaning times in time, and avoid garbage overflow.

3. Folding occupies a small area

Pneumatic pipeline transportation system has high efficiency and high site utilization rate. The collection pipeline in the building is arranged in the pipeline trench, and the garbage transportation pipeline is arranged underground, which can effectively reduce the floor space of the garbage bin house.

4. Less folding flow.

Pneumatic pipeline transportation system transports garbage to the collection center through pipelines, which reduces the transportation of garbage trucks in the community, effectively reduces the impact of collection trucks on residents in the community, and reduces air pollution and noise.

5. Improvement of folding conditions

The pneumatic pipeline transportation system is fully automated, which significantly reduces the labor intensity of garbage collection, improves the collection efficiency and optimizes the working environment of sanitation workers.

6. Flexible folding system

Pneumatic pipeline transportation system has many system forms, which can flexibly meet different functional requirements. The garbage throwing port is located near the user, which is convenient for throwing. The garbage collection process is completed in closed pipelines and collection centers, and is not affected by any weather. The whole system runs automatically with high reliability and can work all day.

Compared with the traditional garbage collection method, the garbage pneumatic pipeline transportation system is an efficient and sanitary garbage collection method, but it also has some shortcomings such as large one-time investment and high requirements for system maintenance and management:

(1) Compared with the traditional garbage collection method, the pneumatic pipeline transportation system can automatically transport garbage.

(2) The pneumatic pipeline conveying system adopts computer programs to control the garbage collection process, which has a high degree of automation. Therefore, the corresponding managers are required to have high management quality, and at the same time, the throwing behavior of throwers should be guided and standardized.

(3) The system needs regular inspection, repair and maintenance by trained technicians to ensure that all components and equipment are in good condition and operate normally.

example

Sweden-

Korea builds a circular ecological circle.

In Binhai New Town, Ma Bei, Sweden, there will be a faint hum coming from the ground sooner or later, which is similar to the sound of a range hood when it works.

In fact, this is an automatic garbage collection system in the underground of Korea. You can think of this system as a combination of an underground pipe and a huge vacuum cleaner. In this special "sewer", the garbage rushes to the garbage collection station on the edge of the community at a speed of 70 kilometers, which is comparable to that of the subway.

In Ma Bei, China, garbage is divided into three categories: organic garbage, combustible garbage and paper, which makes the post-treatment of garbage very efficient. These three kinds of garbage have their own positions. Combustible garbage will be thrown into the incinerator of the local thermal power plant, and part of the energy generated by combustion will be converted into electric energy, and the other part of heat energy will be absorbed by the water flow, which will enter the residents' homes along the "heating pipe" to exert the residual heat. Organic garbage is sent to biogas digesters, and part of the generated biogas goes to residents' kitchens and part of it is supplied to hybrid cars in the community. The remaining residue is used as organic fertilizer and returned to the field. Waste paper is sent to a recycling factory and made into other paper products for further use.

As an important part of the "circular ecological circle", the automatic garbage collection system, coupled with environmental protection and energy-saving technologies such as sewage treatment system, biogas digester, central heating/cooling system, passive energy-saving building, solar energy utilization, "carpooling group" (more than 300 people use 25 cars), makes the house in Korea belong to the surrounding areas even if the house price reaches about 90,000 Swedish kronor per square meter (equivalent to about 67,500 yuan).

All these information are real cases and favorable municipal projects. Because of its high cost and high input cost, it is difficult to popularize it in Beijing and even the whole country. At present, only the future science and technology city in Changping and Tongzhou core areas has such supporting construction, and it is very clean and comfortable to live in such an environment in the later period.
