Description
Technical Field
The utility model relates to a water-cooling plenum technical field specifically is a water-cooling plenum air inlet structure.
Background
The circulating fluidized bed boiler that operates at present generally has the inhomogeneous problem of air distribution, leads to the bed temperature to distribute unevenly, and NOx discharges to stay high. The uneven distribution of the air is usually caused by uneven distribution of primary air flow in a water-cooling air chamber below an air distribution plate, and the uneven distribution is mainly caused by the fact that the tubes of the tube panel are processed by the tubes or fins on the tubes are directly cancelled, so that the kinetic energy of the primary air entering the air chamber is large, the structural stability of the tube panel is reduced due to the structure, the integral rigidity of the air chamber is reduced, and the air chamber cannot bear large air chamber pressure. At present, no better solution is available.
Disclosure of Invention
In order to solve the inhomogeneous problem of current water-cooling plenum air inlet, the utility model provides a water-cooling plenum air inlet structure, it can ensure a wind air current homogeneity, and stable in structure can bear higher plenum pressure.
The technical scheme is as follows: the utility model provides a water-cooling plenum air inlet structure, its includes the water-cooling plenum, the wind channel is once connected to the water-cooling plenum, the water-cooling plenum with the junction in wind channel is provided with the pipe panel, a serial communication port, the pipe panel comprises the pipe that has the fin, the round hole of evenly arranging is seted up to the fin, the round hole diameter is not more than 40mm, be in the same direction as the row or the staggered arrangement between the round hole.
Adopt the utility model discloses afterwards, retained the fin, also need not to make and let the pipe arrange, the bulk rigidity of plenum is big, can bear higher plenum pressure, and rigidity and inertia have been eliminated to the minor diameter air current that is scattered by the major diameter wind columnization in the original primary air duct when the pipe panel to the wind flow makes easily spread to whole plenum to make the amount of wind can follow the grid plane and evenly arrange.
Drawings
FIG. 1 is a front view of a water cooling plenum and a primary air duct;
FIG. 2 is a schematic view of the direction A in FIG. 1;
FIG. 3 is a schematic view of round holes arranged in a staggered manner.
Detailed Description
Referring to the figures 1, 2 and 3, the air inlet structure of the water-cooling air chamber comprises the water-cooling air chamber 2, the water-cooling air chamber 2 is connected with a primary air channel 1, a tube panel 3 is arranged at the joint of the water-cooling air chamber 2 and the primary air channel 1, the tube panel 3 is composed of tubes 5 with fins 4, the fins 4 are provided with round holes 6 which are uniformly arranged, the diameter of each round hole 6 is not more than 40mm, and the round holes 6 are arranged in sequence or in staggered mode. Wherein, fig. 2 is arranged in a row, fig. 3 is arranged in a staggered way, the air flow rate of the cross section of the round hole 6 is 15-40m/s, the primary air entering the water-cooling air chamber 2 is converted into scattered small-diameter air flow by a large-diameter air, the rigidity and inertia are eliminated, the air flow is easy to diffuse to the whole air chamber, the air volume can be uniformly arranged along the plane of the air distribution plate, meanwhile, the fins at the joint of the tube panel of the water-cooling air chamber and the air channel are kept, the integral rigidity of the air chamber is larger than that of the original structure, and the air chamber can bear higher air chamber pressure.
