Heat and steam turbine device for removing moisture from the vapor stream prior to low-pressure cylinder

摘要

The invention relates to the field of steam turbines and is aimed at providing ease of installation, ease of repair and maintenance, as well as improving the efficiency of dripping and, accordingly, the reliability of the turbine installation.; Said technical result is ensured by the fact that the Heat and steam turbine comprises (1) mounted on the same shaft 1 CVP (not shown), MPC and 2 LPC 3 not shown in the drawing Heat selections. Exhaust LPC 3 condenser 4 installed steam. Exhaust IPC 2 connected to input 3 LPC bypass pipe 5 having two vertical section - the upward (in the direction of steam flow) section 6 adjacent to the IPC 2, and descending portion 7 adjacent to the low-pressure cylinder 3. The vertical parts 6 and 7 are combined horizontal portion 8. in the inlet pipe 9 paropriemnoy LPC camera 3 installed moisture collecting device 10 that is connected to drain line moisture (water). moisture removal line (2) is formed from two separate pipelines - the upper 11 and lower 12. The upper pipe 11 is mounted inside the upper portion 13 of chamber paropriemnoy LPC 3 and its outlet section is located at the level of the horizontal joint LPC body 3, The lower conduit 12 is mounted inside bottom portion 14 paropriemnoy LPC chamber 3, the front portion of the lower pipe 12 is provided with a receiving pipe 15, which is wound with a gap upper conduit 11. When this suction inlet 15 above the level of the horizontal connector 3 for LPC values y, ensures reliable removal of moisture from the upper conduit 11 at the bottom of the lower section 12. The output line 12 is supplied with the input directly to the cross section of regular drainage outlet pipe 16 from the bottom of chamber 14 paropriemnoy LPC 3. n.z.p.f-ly 1, 2 Fig.
