Mouthful；
The water inlet of cooling water pipe in the housing wall of the cooling cylinder is arranged at right side wall, then passes through cylinder entrance
Rear wall is entered by bend after left side wall, then again passes through after cylinder enters front side wall and stretches out, and in described housing
The water inlet connection of cooling water pipe；
The cooling cylinder is rectangle；
Cooling water pipe in the housing wall includes multiple delivery ports, and the multiple delivery port connects and as described respectively
The water inlet of cooling water pipe in housing, helically formula is interspersed in the interior of the cooling cylinder to the cooling water pipe in the housing
Portion, and the cooling water pipe parallel arrangement described in each column in housing, the cooling water pipe described in each column in housing include straight tube and elbow,
The straight tube positioned at it is described cooling cylinder inside, the elbow expose to it is described cooling cylinder and be arranged to it is skewed, with true
Certain level interval is kept between two straight tubes at guarantor's elbow both ends.
The ashes that the utility model is applied to CFBB cool down, and the arrangement of cooling water pipe increases on cooling device
Cooling heating surface area is added, the temperature of hot ash can have effectively been reduced through cooling device from the high temperature ashes that returning charge valve comes out, by cold ash
By Geldart-D particle to grey storehouse, whole closed, No leakage, so as to effectively prevent power station environment pollution, thermal loss is reduced,
Reduce simultaneously and potential safety hazard possibility occurs.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the cooling water pipe arrangement schematic diagram in cooling device housing in the utility model；
Fig. 3 is that the cooling water pipe in the utility model in the housing wall of cooling device arranges overlooking the structure diagram.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of cooling furnace apparatus for ash, it includes returning charge valve 1, and the outlet of returning charge valve 1 is welded to connect
The one end of ash tube road 2, the other end of ash tube road 2 are welded to connect cooling device 3, and cold apparatus for ash includes cooling cylinder 6, and it is square
Shape, cool down in the housing wall of cylinder 6 and be placed with cooling water pipe in housing respectively, cool down the cooling water in the housing wall of cylinder 6
The water inlet of pipe 9 is arranged at right side wall, then passes through cylinder into rear wall is entered by bend after left side wall, then wears again
Cylinder is crossed into stretching out after front side wall, with housing in the water inlet of cooling water pipe 11 connect, the cooling water pipe 9 in housing wall
Delivery port 10 connects with the water inlet of the cooling water pipe 11 in housing, in the water inlet of the cooling water pipe 9 in housing wall, housing
The delivery port of cooling water pipe 11 is the water inlet 7 and delivery port 8 of cooling device, the cooling water pipe 9 in housing wall include it is multiple go out
The mouth of a river 10, multiple delivery ports 10 connect and as the water inlets of the cooling water pipe 11 in housing respectively, the cooling water pipe in housing
11 helically formula be interspersed in the inside of cooling cylinder 6, and the cooling water pipe 11 in each column housing is arranged in parallel, in each column housing
Cooling water pipe 11 includes straight tube and elbow, and positioned at the inside of cooling cylinder, elbow exposes to cooling cylinder and is arranged to incline straight tube
