Roller slag cooler
Roller slag cooler is fluidized bed boiler to meet the requirements of the direction of the development of large-capacity design and development. It consists of heat rollers, into Java device, a Java device, rotating mechanism, the drive mechanism, cooling water systems and electronic control devices and other components. Motor through the reducer, power is transmitted to the sprocket chain barrel. So rotating cylinder. Cooling water filled rotating cylinder sandwich and guarantee a certain flow.High-temperature materials through the feed device into the rotating cylinder, with the rotation of the cylinder, the inner sheet material along a spiral path, continuously fed forward. The process of conveying,by a metal wall of good thermal conductivity and low-temperature cooling water countercurrent flow sufficient heat exchange, the water may be heated directly into the deaerator, reduce the input of the heater; slag temperature after cooling below 100 ºC, by belts, bucket chain conveyors and other transportation equipment delivery.
GTLZ slag cooler operating principle
Equipment structural features
1.excellent output regulation performance, high degree of automation
Roller cold slag machine can automatically adjust the speed of rotation of slag cooler under pressure boiler pressure transmitter signal is given when the big furnace slag material thickness when the amount is large, on the contrary it is small. thus achieving the minimum speed contribute to achieve the most reasonable request. Both to reduce equipment wear and tear can greatly reduce the manual adjustment of slag cooler speed labor, especially in the boiler combustion instability advantage of this feature is more pronounced.
2.to adapt to a wide range of particle ash, slag good effect
Unique tube structure, wear resistance, heat transfer surface, long life, no matter the amount of slag ash particle size and number, will not affect the normal operation of slag cooler.
3. the unique structure, reliable long-term leak-proof Java device
Use of anti-spiral leak leak slag and dross receive double ring measures in return, truly dripping slag does not leak.
4. height adjustable support wheels.
By adjusting the support wheel cylinder while maintaining normal height, avoiding the long-running decline drum height gauge the impact leakproof seal gap slag device.
5.long-lasting, reliable rotary joint
My company's rotary joint to further improve on the basis of the US Johnson technology, can be confined to 4.5Mpa, the effect of long-running, reliable, low maintenance and easy.
6. with over-voltage, under voltage, over-temperature, water alarm and other security devices
Road located in the inlet pressure gauge and safety valve, when the water overpressure, slag cooler audible alarm, safety relief protection, undervoltage cold slag machine automatically shut down,and send a signal to alert personnel to run maintenance; slag cooler temperature controller for water monitoring, once beyond the set value,immediately audible alarm,and the cabinet with a remote control interface is reserved for future control room alarm of remote control.
