Description
What dry type water-cooled spiral plate tube bank barrel slag cooler described in the utility model related to is a kind of cooling and exhaust apparatus that is used for power plant's fluidized-bed combustion boiler high temperature furnace slag.
The technical background in this field is: in recent years, the scientific and technical research personnel have developed the multiple matching used cold slag machine of power plant's fluidized-bed combustion boiler that is, as the cold slag machine of oscillating mode, rocking type slag-cooling machine, the cold slag machine of tipping bucket type, the cold slag machine of air drain type, bushing type barrel slag cooler, the cold slag machine of spiral double-water internal cooling, the cold slag machine of rotation dry type sectional-header, cylinder type cold slag machine etc.Though these cold slag machines respectively have characteristics, ubiquity complex structure, the problem that cooling effect is not good enough.Be easy to generate vapour lock in the cooling water flow path, make the hot-spot scaling loss.Cooling water often occurs and leak, lime-ash stops up.The slag phenomenon often appears leaking in the interface position that dreg-inlet hopper links to each other with cylindrical shell.
For existing cold slag machine is improved, in the pluses and minuses of summing up various cold slag machine with on the basis of the experience and lessons in using, we have designed the utility model dry type water-cooled spiral plate tube bank barrel slag cooler.Its objective is for a kind of good cooling results, novel cold slag machine safe and reliable to operation, easy to maintenance being provided for power plant's fluidized-bed combustion boiler.This purpose mainly realizes by following measure: the strand cage in the roller tube is to be welded into the individual layer spiral plate with steel plate system, is passed spiral plate and is welded together the tube bank of formation water-cooling spiral plate with spiral plate by the tube bank direct-axis line direction that steel pipe is formed.Wherein have cooling water to flow through high-temperature ash is cooled off in the tube bank, the main effect of spiral plate is that high-temperature ash is constantly moved until discharge after the landing below tiltedly along spiral plate.Because spiral plate and tube bank weld together, spiral plate can be passed to cooling water in the tube bank to the heat of high-temperature ash, and high-temperature ash is played cooling effect.Spiral plate and tube bank combine, and can play the deslagging effect and can play cooling effect again.
The technical scheme and the embodiment of dry type water-cooled spiral plate tube bank barrel slag cooler described in the utility model are seen accompanying drawing.
