Abstract

The invention discloses a horizontal-type steam turbine condenser. The main viewing shape of each cooling water pipe is an arc which is opened upwards. Each cooling water pipe is of a thin-walled cavity structure. The cross section shape of each cooling water pipe is a major arc which is opened upwards. The lowest point in the horizontal direction of each cooling water pipe vertically communicateswith a condensed water guide pipe. The lowest points of the cooling water pipes are sequentially penetrated by the vertical condensed water guide pipe in the vertical direction, and flow guide holesare formed in the peripheries, corresponding to the lowest points of the cooling water pipes on the lower portion, of the condensed water guide pipe. Water receiving flow guide plates are arranged below the cooling water pipes in parallel, and the cross section shape of each water receiving flow guide plate is an arc which is opened upwards. The lowest point of each water receiving flow guide plate communicates with the condensed water guide pipe. A cooling water inlet chamber communicates with an automatic cleaning device used for cleaning the cooling water pipes. Condensed water condensed byeach cooling water pipe is independently guided to be discharged, supercooling happening due to the fact that the condensed water drips off onto the outer walls of the cooling water pipes on the lower portion is avoided and the blocking phenomenon of a cooling water channel can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of steam turbine condensers, in particular to a horizontal steam turbine condenser. Background technique [0002] The steam turbine, also known as the steam turbine engine, is a rotary steam power device. The high-temperature and high-pressure steam passes through the fixed nozzle to become an accelerated air flow and then sprays onto the blades, so that the rotor equipped with blade rows rotates and works externally. Steam turbines are the main equipment of modern thermal power plants, and are also used in metallurgical industry, chemical industry, and ship power plant. In the steam turbine power plant, the condenser is a very critical component, and its function is to condense the exhaust steam of the steam turbine into water, so it is also called a rehydrator. [0003] According to different steam condensation methods, condensers can be divided into surface type (also known as partition type) and mixed t...
