Efficient condenser with fixed-type flow-around torsion belts

Abstract

The invention discloses a fixed winding twisted belt high-efficiency condenser. The condenser consists of a steam inlet (steam turbine exhaust) port, a condensed water outlet, a circulating cooling water inlet, a circulating cooling water outlet, and a condenser shell. Condenser pipe (several pieces), fixed winding twisted belt and bracket accessories. According to the water quality environment, the fixed winding twisted belt is made of polymer composite material, or made of metal materials such as stainless steel, copper or titanium, and is installed in the condensation pipe. When the cooling water flows through the tube side of the condenser at a certain speed, the fixed winding twisted belt makes the circulating cooling water in the condenser rotate and flow forward, forming a stable turbulent flow, improving the heat transfer capacity of the condenser, and improving the condenser's performance. At the same time, it can reduce the scale or sludge on the wall of the condenser tube. The high-efficiency solid-type flow-wound twisted-belt condenser can be mainly used in condensers in power generation systems, and solves the problem of reduced vacuum exchange degree of condensers in current steam turbine power generation systems.

Description

technical field [0001] The invention relates to a condensation heat exchange device, such as a condenser in a power plant, in particular to a high-efficiency condenser with a fixed winding twisted belt. Background technique [0002] At present, there are many kinds of condensers commonly used in industry and condensers used in the field of power generation, mainly including water-cooled type, air type and evaporative type. However, when using the above types of condensers (especially water-cooled condensers), since the circulating cooling water medium contains a large amount of impurities, especially the temperature of the circulating cooling water is generally between 20 and 35°C, it is especially suitable for the reproduction of algae and microorganisms , a large amount of water in the cooling water will evaporate during recycling, the algae in the cooling water will continue to concentrate, the concentration of calcium bicarbonate in the water will become higher and highe...

AI Technical Summary

Problems solved by technology

The roughness of the pipe wall has a great influence on the fluid flow. The reduced flow rate will in turn increase the adhesion of impurities on the pipe wall. The interaction between the two will cause the scaling phenomenon on the inner wall of the pipe to increase, thereby affecting the condensation effect of the condenser and reducing the heat transfer efficiency. , increasing equipment cost

Seriously affect the popularization and application of condensers
