Cooling water circulator

Abstract

The invention discloses a cooling water circulator comprising a cover plate, a front distribution plate, a tube plate component and a rear distribution plate arranged sequentially. First to N1th water intake areas and second to N1+1th water outtake areas are arranged on the front distribution plate, first to N1th water outtake areas and second to N1+1th water intake areas are arranged on the rear distribution plate, the N2th water outtake area on the front distribution plate is communicated with the N2+1th water intake area, the N3th water intake area on the rear distribution plate is communicated with the N3+1th water intake area, N1+1 groups of tube holes are arranged in the tube plate component, the N1th water intake area on the front distribution plate and the N1th water outtake area on the rear distribution plate are communicated through one group of the tube holes, and the N1+1th water outtake area on the front distribution plate and the N1+1th water intake area on the rear distribution plate are communicated through one group of the tube holes. The cooling water circulator is directly arranged on the outer side of the to-be-cooled equipment, cools the equipment with a primary water source and is large in heat radiating area, high in cooling efficiency, energy saving and low in cost.

Description

technical field [0001] The invention relates to a cooler, in particular to a circulating water cooler. Background technique [0002] The closed circulating water cooler is the key equipment of the closed cooling water system of the thermal power plant. It uses the primary water source (river water or sea water) to cool the secondary water source (closed water, demineralized water), and the secondary water cools and takes away the power plant production process. Some equipment (such as the anchor claw of the steam turbine, the central joint door of the main steam valve and the feed pump seat, etc.) absorb a large amount of heat from the high-temperature fluid, and can also cool the equipment (such as various water pumps) that continuously generate heat due to their own rotational friction. , wind shaft bearings, etc.), and can also cool equipment that generates heat due to energy conversion (such as generators, motors, etc.). , so as to ensure the safe operation of the power...

Problems solved by technology

However, this utility model uses the secondary water source to cool the equipment, which is to introduce the secondary water source into the equipment, and the closed circulating water cooler is set at a distance from the equipment, and does not directly contact the equipment, occupying the installation space; at the same time, the primary, The secondary water source needs to waste a lot of water resources, and the cost is high
