Guide plate for indirect air-cooling heat radiator pipe tank

Abstract

The invention discloses a guide plate for an indirect air-cooling heat radiator pipe tank. The guide plate for the indirect air-cooling heat radiator pipe tank is characterized by comprising a bottomplate, wherein a first side plate and a second side plate with the top parts being welded and fixed to the top part of the inner wall of the pipe tank are arranged on two sides of the bottom plate; multiple small holes with sizes and gaps meeting the fluid flowing speed uniformity requirement are formed in the bottom plate; and holes for ensuring liquid circulation and meeting the bearing capacityrequirements of the side plates are formed in the first side plate and the second side plate. According to the guide plate for the indirect air-cooling heat radiator pipe tank provided by the invention, the guide plate is arranged on a water inlet of the pipe tank, bears the direct impact of a water flow entering the pipe tank, and guides the water flow to pass through the small holes and a specific flow region on the guide plate, so that the distribution of a fluid entering the pipe tank and a pipe bundle is uniform, the erosion of the nonuniform water flow and the horizontal high-speed water flow on a base pipe and the inner wall of the pipe tank is remarkably reduced, the inner wall of the pipe tank and the base pipe of the pipe bundle are effectively protected, the service life of thelife bundle is prolonged, and the aim of protecting the stable and economic operation of an indirect air-cooling system is achieved.

Description

technical field [0001] The invention relates to a deflector for a pipe box of an indirect air-cooled radiator, belonging to the technical field of power station cooling. Background technique [0002] The indirect air cooling tower of the power station is a steam cooling technology adopted by thermal power plants in coal-rich and water-poor areas in my country in recent years. The core components of this technology - the air-cooled condenser water inlet box tube plate and base pipe are washed by the system circulating water for a long time, and are easily damaged and leaked. Frequent repair or replacement of water inlet box and base pipe is required, which seriously affects the normal operation of the power station. run. The early indirect air-cooling tower radiator tube bundle leaked and the tube box was removed, and it was observed that the tube nozzle was washed out and showed irregular gaps. The orientation of the notch has a clear direction, corresponding to the direct...
