In order to solve the problems of the technologies described above, the convertible straight-tooth of high temperature ablation intelligence of keeping away that the utility model provides cools off the dynamic poker mechanism of multi-region, comprise the mobile jib that pokes fire, the described mobile jib that pokes fire is the bendable mobile jib that pokes fire, the poke fire dogleg section of mobile jib of described bendable is provided with many group straight-tooth, the described bendable mobile jib that pokes fire is made up of mobile jib outer tube and mobile jib inner sleeve, described straight-tooth is made up of straight-tooth outer tube and straight-tooth inner sleeve, described straight-tooth inner sleeve is connected with described mobile jib inner sleeve, described straight-tooth outer tube communicates with described mobile jib outer tube, the poke fire described mobile jib outer tube of mobile jib of described bendable is connected with the forced circulation cooling system respectively with the mobile jib inner sleeve, and the described bendable mobile jib that pokes fire is connected with overturning drive device.
Described overturning drive device is the intelligent numerical control overturning drive device.
The design of water resistances such as described straight-tooth employing.
Adopt the convertible straight-tooth of high temperature ablation intelligence of keeping away of technique scheme to cool off the dynamic poker mechanism of multi-region, adopt convertible design, realized the multizone function that dynamically pokes fire, the stove bar adopts the bendable design, be not subjected to the restriction of body of heater mounting condition, this equipment body of rod can free adjustment, allows mobile jib be in low-temperature space, has avoided high temperature ablation and coking, this equipment has adopted the straight-tooth cooling, realized the straight-tooth forced circulation, cooling water inflow reduces greatly, can use Large Furnace.Because body of rod amount of cooling water is low, for the very high steam generator system of backwater rate, can use equally.Power-equipment adopts the intelligent numerical control mode, to zone and the speed flexibility control of poking fire, can cooperate fuel band to regulate, and the equipment that makes improves the fractional energy savings height greatly to the coal applicability of fuel.
In sum, the utility model is that a kind of high temperature ablation of keeping away dynamically pokes fire, allows the coal seam effectively mix with air in whole combustion process with coking, multi-region, makes boiler efficiency improve, can be applied to Large Furnace, the safe and reliable dynamic poker mechanism of the convertible straight-tooth cooling multi-region of high temperature ablation intelligence of keeping away greatly.
