Embodiment
Following examples are used to illustrate the utility model, but are not limited to scope of the present utility model.
As shown in Figures 1 to 4, drum blow down cooler described in the utility model includes shell 1, drum blowdown inlet tube
2nd, drum waste pipe 3, heat exchanger tube 4, cold water inlet tube 8 and cooling water outlet pipe 9, described heat exchanger tube 4 are arranged on shell 1
Inside, described drum blowdown inlet tube 2 is connected with the entrance of heat exchanger tube 4, outlet and the drum waste pipe 3 of heat exchanger tube 4
Connection, the net sectional area of drum blowdown inlet tube 2 is more than or equal to twice of the net sectional area of heat exchanger tube 4, drum blowdown
The net sectional area of outlet 3 is more than the net sectional area of drum blowdown inlet tube 2.
Described drum blowdown inlet tube 2 and drum waste pipe 3 is separately positioned on the left and right ends of shell 1, cold water
Inlet tube 8 and cooling water outlet pipe 9 are separately positioned on the center of the both sides up and down of shell 1, cold water inlet tube 8 and cooling water outlet pipe 9
Axis is perpendicular to drum blowdown inlet tube 2 and the central axis of drum waste pipe 3.
Described heat exchanger tube 4 includes the first finned cooling pipe 5, the cooling of the fin of spiral cooling tube 6 and second being sequentially connected in series
Pipe 7, the wherein net sectional area of spiral cooling tube 6 are less than the effective cross-section of the first finned cooling pipe 5 and the second finned cooling pipe 7
Product.
As shown in figure 4, described heat exchanger tube 4 includes 2 first finned cooling pipes 5,2 spiral cooling tubes 6 and 4 second
Finned cooling pipe 7, drum blowdown inlet tube 2 is connected with every first finned cooling pipe 5 respectively, every first finned cooling pipe 5
Connected with every spiral cooling tube 6, with every after every two second finned cooling pipes 7 parallel connection in 4 second finned cooling pipes 7
Spiral cooling tube 6 is connected.
Net sectional area described in the utility model refers to the sectional area for the pipeline that drum blowdown steam water interface passes through,
When steam water interface shunting is by multiple pipelines, refer to the sectional area sum of these pipelines；Section of drum blowdown inlet tube 2
Area is larger, and when drum blowdown steam water interface enters drum blowdown inlet tube 2, flow area is extended first, is then reduced
