Problems solved by technology

[0002] As we all know, the waste water blowdown expander used in power plants is an auxiliary device for waste water blowdown, which has been widely used in the field of waste blowdown expanders; the existing waste water blowdown used in power plants The expansion container includes a shell, legs, water inlet valve, water outlet valve, cylindrical partition, steam-water separator and exhaust pipe. The inlet is connected, the top of the water outlet valve is connected to the sewage outlet, the cylindrical partition is installed inside the cavity of the shell, the left end of the shell is equipped with a pressure gauge, the top of the steam separator is installed at the air outlet on the top of the shell, the bottom of the exhaust pipe is connected to the The top of the air outlet of the shell is matched and connected; when the existing waste water sewage expansion container is used in the production of power plants, the water inlet valve is first connected with the waste water discharge pipe, and then the sewage is discharged on the cylindrical partition at the bottom of the shell Tangential movement in the interior, and immediately vaporized into secondary steam, separated by the steam-water separator on the top of the shell, the steam is discharged through the exhaust pipe for recovery, and the vaporized sewage can be discharged out of the shell cavity through the water outlet valve; now In the use of a waste water expansion container used in the production of power plants, it was found that the existing device would cause debris to accumulate, precipitate and remain inside the cylindrical partition when the waste water was discharged for a long time. It is difficult to manually disassemble the existing device , resulting in more complex internal cleaning, poor adaptability, and higher use limitations
