Description

Title of Invention: Anti-pollution Vacuum Cylinder Exhaust System

Technical field

[0001] The present invention relates to an anti-pollution vacuum cylinder exhaust system, and belongs to the field of industrial pneumatic transmission equipment.

Background technique

[0002] At present, China's economic scale and comprehensive strength have grown substantially, and economic development has achieved remarkable achievements, but it has also paid a lot of energy resources and environmental costs. The development of the manufacturing industry and even the entire national economy is seriously constrained by resources, energy and the environment. If the growth of the manufacturing industry in the next 20 years depends solely on the increase in quantity, this cannot be borne by resources, energy and the environment. Transforming the mode of economic growth and taking the road of scientific development has become an urgent requirement for economic and social development. Peer is also the fundamental way to achieve energy conservation and consumption reduction goals. Therefore, China must rely on scientific and technological progress, adopt green manufacturing technology, and strive to reduce resources and energy consumption while improving product quality and added value. This is the future development direction of manufacturing. Energy conservation and consumption reduction in China has become the essential requirement of the scientific development concept. Energy-saving technology research has important practical significance and has become an important issue in various industries in the industry.

[0003] Pneumatic technology is a technology that uses compressed gas as a working medium to transmit power or information by gas pressure to achieve mechanization and automation of production. Since the 1970s, it has been widely used in the field of industrial automation. It has formed a global market with annual sales of about 11 billion US dollars. The annual sales in China has reached nearly 5 billion yuan. It occupies a considerable proportion of use in industrial production. However, the working medium of a pneumatic system has a high manufacturing cost and a relatively low energy utilization rate. 96% of the energy consumption of compressed air systems is the power consumption of industrial compressors. The power consumption of industrial compressors in China is 180 billion kWh in 2006 and 200 billion kWh in 2007, accounting for about 6% of the country's total electricity consumption. Japan's industrial compressors, which have a GDP of 1.6 times that of China, consume only 40 billion kWh. This shows that we urgently need to greatly improve the energy efficiency of compressed air systems. Therefore, the energy saving and consumption reduction of pneumatic systems has attracted more and more attention. Especially in today's rising crude oil and outstanding energy problems, the problem of serious waste in the use of pneumatic systems has also attracted people's attention. How to improve the utilization rate of compressed air is becoming an important and urgent issue in China.

technical problem

[0004] Among them, in industrial production, vacuum is used as a power source, as a means of achieving automation, vacuum system It has been widely used in many aspects, such as carrying out handling operations. There are generally two methods for generating vacuum. One is to use a vacuum pump to pump the air out of the container to generate a vacuum, and the other is to use compressed air to form a high-speed airflow through a nozzle in the vacuum generator to convert the pressure energy of the gas into The aeration of the gas stream thus creates a vacuum at the outlet of the nozzle, thereby creating a vacuum suction. The latter method is widely used in automated production equipment.
