Clean coal development and use is one of the important content of the scientific development of the national economy, and the entrained flow as the representative of modern large-scale coal gasification technology application and promotion of clean coal development utilization to provide technical support, but the resulting environmental problems has become the focus of attention, "three wastes" resource use has become a problem that must be paid attention to in the enterprise. Hao source company aerospace furnace powder coal gasification device is a dry pulverized coal as raw material, the quench process for the production of crude synthetic gas gasification device, formed after combustion of pulverized coal ash mixed in water, and synthesis gas scrubber bottom exhaust Blackwater together into slag water system, filter cake is formed by sedimentation, filtration and other treatment generated every day about 150 tons. The slag processing has been a problem plagued the company, before the company by the investment at the price of $20 per tonne of commissioned third-party Sinotrans. Even so, the slag field often pile up like a mountain hand caused great damage to the surrounding environment, and seriously affect the corporate image.
The company leadership attaches great importance to environmental issues caused by ash recycling, put forward ideas. Through investigation and study, the fixed carbon content of 30% ash sent to the boiler blending. Not only the use of the residual carbon in the cake, and simultaneously solves the problem of environmental pollution.
Project started construction in the second half of 2016, 2 in 2015, the project installation and construction completed. The device through a belt machine will be cake is transported to the hopper and through the blender mixing evacuation to paste pump. By paste pump pressurized conveying to the boiler blending. 2016 February 24, the device an official car, and a drive to succeed, marks the Haoyuan company in aerospace furnace slag processing step to a new level.
