Description

Pipe penetrating guide mechanism for copper pipe of condenser

Technical Field

The utility model relates to an assembling tool for a condenser of a power plant, in particular to a pipe penetrating guide mechanism for a copper pipe in the condenser of a gas power plant.

Background

The condenser is one of main auxiliary equipment of a gas power plant (a thermal power plant), steam discharged by a low-pressure cylinder of a steam turbine enters a condenser box body, is cooled by circulating cooling water in a copper pipe of the condenser and is converted into condensed water, and the condensed water is conveyed to a condensed water feeding system of a boiler; the condenser is a closed box structure, a plurality of parallel middle tube plates are arranged in the box at equal intervals, nearly 9000 condenser copper tube through holes are densely distributed on each middle tube plate, a water inlet chamber is arranged at the front end of the box, and a water outlet chamber is arranged at the rear end of the box; 9000 condenser copper tubes are connected between the water inlet chamber and the water outlet chamber in a penetrating manner; circulating cooling water sequentially passes through the water inlet chamber, the condenser copper pipe and the water outlet chamber to circulate, and steam discharged by the low-pressure cylinder of the steam turbine enters the box body from the upper part of the box body structure of the condenser and passes through the outer side wall of the condenser copper pipe; steam entering the condenser and cooling water in the copper pipe realize steam-water heat exchange, and the steam is condensed into condensed water; in the installation of a condenser of a newly built power plant, when a box-shaped shell of the condenser and an intermediate tube plate are installed in place, the tube penetrating assembly work of a copper tube of the condenser is required; in a condenser box, 12 layers of middle tube plates are generally arranged in parallel, 9000 through pipe holes of a plurality of copper tubes are densely distributed on each tube plate, the tube plate pipe holes on the 12 tube plates are correspondingly arranged, and condenser copper tubes need to be sequentially inserted into the end plate pipe holes and the corresponding tube plate pipe holes on the 12 layers of tube plates on site, so that the condenser copper tubes cannot be inserted wrongly; because the copper tube of the condenser is made of copper, the copper tube is soft in texture, and the phenomenon that the port part of the soft copper tube collides with the tube hole of the tube plate which is hard in texture is easy to occur in the tube, so that the copper tube is damaged, and the heat exchange work of the subsequent copper tube is influenced; therefore, when the pipe penetrating operation is carried out on site, a constructor must be arranged beside 12 pipe plates in the condenser box body to assist the penetrating copper pipes to safely penetrate through pipe plate pipe holes on the pipe plates, the phenomenon of serial penetrating connection when the condenser copper pipes penetrate the pipes is avoided, and the phenomenon that the pipe orifices of the copper pipes are collided and damaged is avoided.
