Waste water discharge flash tank applied to power plant production

Abstract

The invention relates to the technical field of discharge flash tanks, in particular to a waste water discharge flash tank applied to power plant production. The waste water discharge flash tank reduces the cleaning difficulty of a device, improves the cleaning convenience, increases the use stability of the device and reduces the use limitation. The waste water discharge flash tank comprises a shell, supporting legs, a water inlet valve, a water outlet valve, a cylindrical partition plate, a steam-water separator and an exhaust pipe, wherein the top ends of the supporting legs are cooperatively installed at the bottom end of the shell, the right end of the water inlet valve communicates with a sewage inlet of the shell, the top end of the steam-water separator is installed at a top air outlet of the shell, and the bottom end of the exhaust pipe cooperatively communicates with a shell air outlet; and the flash tank further comprises the exhaust pipe, a motor frame, a motor, a sealing ring, a rotating shaft, a connecting arms and a mounting plate, the motor is mounted at the bottom end of the shell through the motor frame, the sealing ring is mounted in a groove hole in the bottom end of the shell, the rotating shaft is coaxially matched and rotationally connected with the sealing ring, the bottom end of the rotating shaft is coaxially connected with the top output end of the motor, and the mounting plate is connected with the rotating shaft through a plurality of connecting arms in a matched mode.

Description

technical field [0001] The invention relates to the technical field of expansion vessels for sewage discharge, in particular to an expansion vessel for sewage discharge used in power plants. Background technique [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...

[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
