The hydraulic slag discharge system consists of a dehydration bin, a high-efficiency thickener, a buffer tank, a pipeline, and various pump valves. The slag discharge process is as follows: the mortar from the bottom of the furnace and the mortar pump behind the furnace are continuously injected into the dehydration silo, the ash and slag slowly settle down, and the sawtooth-shaped overflow weir around the upper mouth of the clearer gray water bin overflows and flows In the high-efficiency thickener, the concentrated mortar is still pumped back to the dehydration bin. The fresh water in the high-efficiency thickener enters the buffer tank, and the buffered mortar is pumped back to the dehydration tank, and the clean water is connected to the circulating water system.
Dehydration bin equipment description
Dewatering bin is a device with three functions: dewatering, storage and unloading. The slag is transported to the dewatering bin for dehydration. After the deposited slag level reaches the rated height, the slurry injection is stopped and the water is quietly considered after 5 to 8 hours, so that the slag moisture content is less than 25%. Finally, the bottom slag discharge gate The dehydrated ash is discharged and loaded for transportation. Two dewatering bins are generally installed and used alternately. When one dewaters and slags out statically, the other one enters the slurry. The flowing water discharged from the dehydration bin is a closed circulation system. After sedimentation treatment, it is used as a water source for the boiler slag flushing system, which can save water and reduce pollution.
High-efficiency thickener equipment description
The high-efficiency thickener is mainly used for slurry concentration in the slag removal system. It can also be used as a further sedimentation equipment for sewage separation such as dewatering silo. The equipment has the advantages of small size, high concentration efficiency, water saving, energy saving, strong adaptability, small project investment, short construction period, and quick results. The automatic harrow lifting device is adopted, which can effectively protect the main transmission equipment when a failure occurs.
Buffer pool equipment description
The buffer tank is an important device for reprocessing and repurifying the overflow water from the high-efficiency thickener. The equipment has the characteristics of compact structure, obvious purification effect and no leakage.
Steel ash warehouse, desulfurization absorption tower
Steel ash warehouse and desulfurization absorption tower are large-scale steel structure equipment provided by our company for users of power plants. All of these products are made of metal and assembled on site. They are excellent substitutes for similar cement equipment. Application, has been widely praised by users.
Main technical features
The product's structural design and strength design use the NASA IDEA-S software system dedicated to rocket analysis. This software system can simulate each of the equipment through simulation (such as earthquakes, temperature changes, wind direction, static load, dynamic load). The strength node performs mathematical analysis by finite element method to maximize the product structure, greatly reduce the design cycle, and save the amount of metal materials.
All parts are factory-processed, such as the cylinder ring is arced and welded grooves are processed. The key stressed components are prefabricated and destressed and inspected.
The product only needs to be assembled and welded on site, the construction area is very small, the installation safety is high, the installation is simple, and the construction cycle is one-third of the similar cement equipment.
The surface of all parts is shot blasted and coated with anti-corrosion coating. The coating is firm and uniform, smooth, free of oil stains, damage, air bubbles, slag inclusions, cracking and peeling, wrinkling and mottled defects, and will not be affected by steel The subsequent elastic deformation or thermal expansion and contraction caused by ambient temperature, etc., cause the coating to fall off.
The appearance is beautiful, the service life is long, and the cost is equivalent to that of similar cement equipment.
