Construction method of condenser

Abstract

The invention discloses a construction method of a condenser. The method comprises the following steps: S1, a foundation is constructed in the position where the condenser is mounted, and all components of the condenser in bulk are assembled in a shell while construction of the foundation is performed, before construction of the foundation or after construction of the foundation; S2, sleepers are laid beside the foundation; S3, rails are laid on the sleepers; S4, the shell assembled in S1 is lifted onto the rails; S5, a throat part of the condenser is welded onto the shell; S6, the condenser with the throat part welded in S5 is hauled onto the foundation; S7, penetration of cooling water pipes is performed. By adoption of the method, assembly of the condenser and construction of the foundation can be performed simultaneously, so that the construction period of the condenser is shortened, and the working efficiency is improved; the problem of high construction difficulty caused by narrow installation sites can be effectively solved; besides, a lifting auxiliary reinforcement measure is taken during lifting of the shell of the condenser, that is, through holes are formed in the shell and steel pipes penetrate through the through holes, the structure is simple, the method is easy to realize, and the cost is low.

Description

technical field [0001] The invention relates to a construction method of a condenser, which belongs to the technical field of installation and construction of large-scale equipment in power plants. Background technique [0002] Due to the large size and inconvenient operation of the condensers in thermal power plants, the components of the condensers in thermal power plants are shipped in bulk at present, and after arriving at the construction site, the overall splicing is completed according to the drawings provided by the factory. [0003] The condenser mainly includes a shell, a neck, a hot well, a side plate, a bottom plate, a tube plate, a baffle, a support pipe, an exhaust pipe, a cooling water pipe, and a front and rear water chamber, etc. The general hoisting plan is: foundation construction preparation→hot well combination installation→shell combination installation→baffle plate in place→exhaust steam connection pipe combination hoisting→neck combination installatio...
