Brief description of the drawings
Fig. 1 is the structural representation of described high temperature coke powder cooling device.
Detailed description of the invention
As shown in Figure 1, described high temperature coke powder cooling device comprise cylindrical vessel body 1, cooling tube group 2,Outer cooling pipe box 3, hopper 4, point bell 5, hydroecium 6, charging aperture 7, discharging opening 8, cooling waterImport 9, coolant outlet 10.
Described cylindrical vessel body 1, point bell 5 and hopper 4 adopt welding or flange connect composition originallyThe coke powder supporting body of high temperature coke powder cooling device is also taken on the function that makes the even cooling discharge of coke powder; Cooling outwardSleeve pipe 3, hydroecium 6, cooling tube group 2 form the closed circulation cavity of cooling water, are responsible for even cooling JiaoPowder; The charging aperture 7 of high temperature coke powder is positioned at its upper side central authorities, adopts weld connection with hydroecium 6; CoolingPipe group 2 is welded with hydroecium 6, inserts in cylindrical vessel body 1 hydroecium 6 and outer cooling pipe box 3 flangesConnect.
In cylindrical vessel, the many two-layer equation cooling tubes that comprise inner tube, outer tube are evenly set, cooling tubeCaliber and quantity according to cooling high temperature powder amount and need cooling rear temperature determine. In addition, at cylinderVessel 1 top arranges entrance hydroecium and the outlet hydroecium of upper and lower relation, described entrance hydroecium and coolingPipe inner tube and outer cooling pipe box 3 are communicated with, the outer tube of described outlet hydroecium and cooling tube, entrance hydroecium and outerCooling pipe box 3 is connected, and described entrance hydroecium is connected with cooling water inlet 9, described outlet hydroecium andCoolant outlet 10 is connected, and the height of described cooling water inlet 9 is lower than coolant outlet 10.
The bottom of described cylindrical vessel body 1 is provided with hopper 4, and distribution coke powder is set in hopper 4Point bell 5, flows downward so that the coke powder in cylindrical vessel can homogeneous.
Implementation method of the present invention is as described below: comprise the cylindrical vessel body 1 as cooling device,The two-layer equation cooling tube that in cylindrical vessel body 1, many of spread configurations are made up of inner and outer pipes at regular intervalsGroup 2, coke powder is mobile, cooling between cooling tube group 2 and outer cooling pipe box 3.
