DEVICE FOR PURIFYING STEAM EXTRACTION OF TURBINE Russian patent published in 2019 - IPC B01D45/12 B01D46/30 

FIELD: power engineering.

SUBSTANCE: invention relates to heat engineering and can be used at thermal power plants during operation of heat-recovery turbines for cleaning from oil extraction (secondary steam). Proposed device comprises turbo charger composed of cylindrical body with conical bottom. Oil-cleaners are grouped into a battery. Each of oil cleaners is connected to the steam extraction pipeline equipped with a shut-off device and closed with a removable cover. Inside the oil cleaner housing there is an annular cylindrical basket with perforated walls, filled with a nozzle in the form of granulated blast-furnace slag, forming an inner cavity, central tube accommodates central pipe with its top end passed through cover center to outside to make cleaned steam discharge branch pipe communicated with cleaned steam pipeline equipped with locking device. Housing is equipped with upper branch pipe of steam inlet, which is tangentially connected to inner cavity. Upper branch pipe is connected to the steam extraction pipeline and through the gas line of purging flue gases equipped with a shut-off device and a delivery pipeline of a smoke exhaust fan. Lower branch pipe is connected to a drain pipeline equipped with a shut-off device, and through a gas line of back purging flue gases, equipped with a shut-off device, with annular channel of secondary air of the boiler burner. Headers of steam, cleaned steam, purging flue gases and return flue gases are connected to appropriate pipelines of each oil filter.

EFFECT: higher efficiency.
