The HWL Series Decanter continuous centrifuge
First, an overview
Decanter centrifuge is a horizontal spiral unloading, and continuous operation of the deposition equipment. The centrifuge works as follows: the drum and the screw to a certain differential high-speed rotation, the material from the feed tube for the introduction of the material conveying spiral inner cylinder into the drum accelerated in the centrifugal field, the heavier solid phase deposition of sediment layer formed in the drum wall. Expected to lose the spiral deposition of solid phase continuous push to drum cone end, by slagging from the plane. The lighter the liquid material to form the inner liquid ring, continuous overflow the drum by the drum big endian overflow port, through the drain line from the plane. This function at full speed, continuous feeding, separating, washing, and discharge. With a compact, continuous operation, smooth operation, adaptability, large capacity, easy maintenance features. Suitable for the separation with solid phase particle size is greater than 0.005mm, the concentration range of 2-40% of the suspension. Widely used in chemical industry, light industry, pharmaceuticals, food, and environmental protection industries.
Second, the selection of Decanters
Select the appropriate Decanters can not only solve the production problems, improve work efficiency, but also savings in production costs, reduce business risk. The main factors affecting the selection of the following:
A rotational speed of the centrifuge: General Decanters above 3000 rpm, the higher speed, higher centrifuge separation factor, the separation, the better.
2 centrifuge Material: different materials the wear resistance, corrosion resistance and other physical and chemical indicators do not like foreign Decanters minimum material 316L, Duplex stainless steel, the abrasive elements are required to use ceramic composites.
(3) the differential speed of the centrifuge control: differential control accuracy, and a great gap between life expectancy and maintenance costs, the higher the accuracy of the differential, the better adaptability to raw materials, it is better to use the differential speed and high precision equipment .
Aspect Ratio: Decanters the aspect ratio of the greater, the greater processing capacity, the moisture content of the smaller.
Control system: control for automated programming of domestic and foreign equipment manufacturers have basically achieved the fully automated control of the device.
6 Installed power: the impact on the control of energy consumption, domestic equipment energy consumption is high, energy consumption abroad than low.
Manufacture process: Decanters are high-precision processing requirements of separation equipment, does not have a maintenance rate of production of the product finishing capabilities, with limited processing power.
Three Decanters on the environmental status:
Decanters mainly refers to the dewatering of the sludge generated in the industrial and civil wastewater treatment processes in environmental applications. Today's environmental issues become the focus of attention of the world, the value to be reflected in this context, Decanters, before wastewater treatment plant or treatment plant are condensed from settlement or using a belt filter press sludge dewatering, tests to prove: the sludge moisture content from 98% to 80%, 10 times its volume can be reduced, because of this, Decanter Decanter centrifuge has handled a large amount of automation, the dehydration effect due to its inherent in the environment The protection of areas of extensive use and promotion. Decanters single product sales accounted for about half of all centrifuge products, has laid its irreplaceable position. In other countries, sewage treatment equipment preferred Decanters.
Fourth, the application of industry-wide
