Review Wulan County is located in Khan Connaught region of the Qinghai Qinghua Group Coal Chemical Industry Park, Qaidam recycling economy is a major project to test area. This large-scale coal enterprises since the beginning of formal operation, the use of advanced production techniques, Run capacitor gas, tar, full recovery and utilization of waste heat, advanced technology, reasonable blending programme, higher production enterprise resource utilization Jieru of the various links. In order to effectively save electricity, the first in this enterprise-wide factory both high and low voltage power supply system using high and low voltage capacitor automatic reactive compensation equipment and greatly reduce network losses; Second, high and low voltage electrical power are used from the control of soft starter moving substantially reduced starting current, but also ensures the stability of variable distribution system safe operation; three coke oven is the main equipment are used VVVF energy-saving motors and ancillary equipment; four Run capacitor water to the water supply system is adopted VVVF constant pressure water supply equipment, Festival of electricity up 20 to 50 percent; five factory is lighting roads and industrial plants are to use energy-saving lights, and take-control and time controller for automatic control.

Char production of energy required to input a large number of fresh water, for more conservation and use of water resources, this enterprise in the design under review Khan Connaught local environmental features, construction, the largest capacity per hour of 65 cubic metres of Materialized treatment plant, all the coke quenching sedimentation tanks, steam condensate recovery tanks, ponds and other facilities reuse treated water all closed-cycle, and raise the utilization rate of water reused, to conserve precious water resources, and effectively reduce water consumption, and achieve zero emissions.
In order to effectively reduce the production of coal raw materials coal and prevent the depletion of coal fuel stored too long of degeneration, enterprises also designed the installation in the coal yard building 18 m high wind and dust suppressants in the wall, effectively prevented by the wind Yat coal dust, in the heat of coke oven improve efficiency, in terms of reasonable selection for different parts of the corresponding insulation materials, improving the thermal efficiency of coke in coke oven technology, the use of water-sealed tube of the bridge, sealed increase performance, reduce Gas Yat, in the use of water of different temperature water and steam pressure parameters, as far as possible cascade use in the gas purification, the use of new efficient heat transfer equipment, high-temperature materials full recovery of the energy use Surplus coke oven gas, which is central heating plant, gas supply, maximum energy Run capacitor conservation. brass ball valve |
