Description
Technical field
The present invention relates to the cap structure technical field in air-distribution device, a kind of blast cap for CFBB.
Background technology
Combustion technology of circulating fluidized, as the coal combustion technology of a kind of advanced person, because of its good fuel tolerance, higher efficiency of combustion, superior environmental-protecting performance and load adjustment ability, has a wide range of applications in the field such as station boiler and Industrial Boiler.Air-distribution device is one of critical component in Combustion Devices on Circulating Fluidized Bed Boiler, its performance directly affects flowing, burning and the diabatic process in the fluidized status of fluidized-bed combustion boiler and combustor, and then have influence on the performance of fluidized-bed combustion boiler, and the air cap device most important assembly that is it.Therefore, the quality of air cap device design directly influences the properly functioning of CFBB, is very important to CFBB.
It is machined with exhaust vent in the horizontal direction on existing blast cap outer wall, causes bigger soot particle to be blocked in exhaust vent, and be easily washed into adjacent blast cap from exhaust vent air-flow out, easily cause blast cap abrasion；Blast cap is blown, and windage is too small, and fluid effect is the best.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of blast cap for CFBB, it can effectively prevent air holes blocking and can optimize fluid effect, improves efficiency of combustion.
Its technical scheme is such that a kind of blast cap for CFBB, it includes blast cap head and adapter, described blast cap headgear is loaded on described adapter upper end, the boss of described adapter is connected bottom described blast cap head, it is characterized in that, described adapter upper portion side wall along the circumferential direction has at least two row's adapter air holes, and described blast cap head lower sides along the circumferential direction has blast cap exhaust vent, described blast cap exhaust vent is downward-sloping layout, and described blast cap head bottom welding connects the boss of described adapter.
It is further characterized by, and adapter air holes described in two adjacent rows is staggered to be evenly arranged；
Described blast cap exhaust vent at least includes two rows, and blast cap exhaust vent described in two adjacent rows is staggered to be evenly arranged；
Described blast cap exhaust vent be downward-sloping angle be 10 °-20 °；
It is protruding that described blast cap head is provided with bamboo shape, has 45 ° of chamferings inside described blast cap head bottom opening, and described blast cap head base point solid welding connects the boss of described adapter surely.
After using the structure of the present invention, adapter upper portion side wall along the circumferential direction has at least two row's adapter air holes, blast cap head lower sides along the circumferential direction has blast cap exhaust vent and is in tilted layout, owing to exhaust vent is the inclined hole tilted, the bigger soot particle being mingled with at air outlet flows to the outside of blast cap outer housing under gravity along exhaust vent, greatly reduce the probability that bigger soot particle is blocked in exhaust vent, also avoid the adjacent blast cap of airflow scouring simultaneously, decrease the abrasion of blast cap, but also cloth wind can be made more uniform；Adapter air port is opened in adapter top side, at least two row, strengthens blast cap air-supply windage, optimizes bed fluid effect, improve efficiency of combustion；Two adjacent row's adapter air holes and blast cap exhaust vent are all staggered to be evenly arranged, and prevents air holes blocking further and optimizes fluid effect, preferably improve efficiency of combustion, blast cap exhaust vent be downward-sloping angle be 10 °-20 ° so that air-out is convenient.
