At present, the demonstration project of modern coal chemical industry represented by coal-based methanol, coal-to-liquid, coal-to-olefin, coal-based ethylene glycol and coal-based natural gas has made significant progress in China. At present, the world's first direct liquefaction plant of millions of tons of coal has been completed, three sets of 160,000-ton coal indirect liquefaction plant, three sets of large-scale coal-to-olefin plant, one set of 200,000-ton coal-based ethylene glycol plant, and two The first phase of the 4 billion m3/a coal-to-gas project has also been completed and put into operation. The coal-to-methanol capacity has reached more than 5,000 t/a (including hydrazine). From the development of 2012, in addition to coal-based methanol due to unbalanced development of downstream products or low profit, other projects as long as the realization of long-term operation, economic benefits are relatively good, compared with oil and gas chemicals, some products have a certain comparison Advantage.
China is a country that lacks oil, gas, and coal. There is a serious shortage of oil and natural gas resources and long-term dependence on imports. At present, the dependence on foreign oil has exceeded 60%, and the dependence on natural gas has exceeded 30%. Coal is still the main energy source of China for a long time.
Wang Xianzheng, president of China Coal Industry Association and chairman of China Coal Association, believes that China's modern coal chemical industry is an inevitable choice for coal enterprises to extend the industrial chain, adjust the industrial structure, and increase the added value of products. Scientifically develop modern coal chemical industry, promote the transformation of coal from fuel to raw materials and fuel, replace and replace some oil and natural gas resources, accelerate the adjustment of coal structure, transform the mode of economic development, promote the transformation of coal production and utilization methods, and reduce the dispersion of direct coal combustion. The environmental pollution caused and the protection of national energy security are of great significance.
Since 2012, the downturn of the coal economy has been grim, and the constraints on resources and environment facing the development of the industry have been continuously strengthened. Wang Xianzheng believes that coal enterprises must transform the long-term development model of single coal mining and coal selling, promote clean and efficient coal conversion, accelerate the transformation and upgrading of the coal industry, improve the ability to cope with market risks, and improve China's energy security.
At the end of last year, China issued the "Guiding Opinions on Promoting the Scientific Development of Modern Coal Chemical Industry in the Coal Industry". The "Guidance Opinions" proposes that priority should be given to the top-level design of coal chemical development, to do a good overall planning, and to achieve coordinated and coordinated development.
The "Guidance Opinion" proposes to strive to complete the large-scale engineering demonstration of modern coal chemical industry, demonstration of new technologies and demonstration of new technologies and new products, and realize long-term commercial operation of demonstration projects by 2020; strive to achieve 1 billion tons around 2030 The conversion of chemical raw materials for coal (excluding coking), the commercialization of various technologies, processes and equipment, energy efficiency and production of sewage to reach new water.
Concrete Pile Pre-stressed/Tension Machine
Concrete Pile Pre-stressed/Tension Machine:
Tension Machine is a kind of feedthrough pre-tensioing. It is also called spun pile tension jack machine, pole tension machine, prestressed tension machine etc. It is the neccesary equipment to produce Pre-stressed concrete spun pile and prestressed concrete pole products. As the end of the tension rod is connected to the anchor with thread, it can be applied to various forged anchors, chilled iron anchor used for stayed-cable bridge and other similar anchors, as well as pre-tension pulling for pipes. In accordance with actual requirement.
HH Tension Machine's advantages:
1. The large-screen LCD display.
2. Double control mechanism of touch screen and keyboard, high reliability.
3. Directly work after the input of tensioning data, and the oil cylinder will automatically complete the tensioning process to reduce uncertain factor of manual operations and improve the tensile quality.
4. Built-in SD card function, which can save the tensile data to the computer regularly, and check the record at any time.
5. With its own printer, it can print tensile data in working time, avoiding the tedious and unstable manual record and ensuring the traceability of tensegrity data is verified.
Technical Parameter:
1. Oil pump flow: 12L/min
2. Motor power: 7.5kw
3. Rated power: 31.5Kpa
4.Tension force: 2000KN
5. Tension stroke: 200mm
6. Programmable controller of automatic control system + input and output of analog data Color touch screen, USB interface output
7. Control voltage: 380V+24V
8. Accuracy of prestress control:±0.1Mpa
9. Data transmission rate is 100%
Main configuration:
Automatic tension control system, 300T jack, oil pump, lifting trolley, tensioning rod, tensioning head and supporting foot.
