Abstract

The invention discloses a condenser cleaning device based on an impeller turbulent flow effect. The device consists of torsion spring tripods at two ends for fixing with the inner wall of a heat exchange pipe, and an impeller set in middle for reinforcing turbulent flow. The torsion spring tripods consist of cylinder bases and torsion springs; the torsion springs are mounted on outer bosses of the cylinder bases to form triangular structures with the same included angles; and impellers are mounted in inner bosses of the cylinder bases through shafts and bearings. The middle impeller set is formed by serially connecting multiple impellers by a shaft; and the shaft and the impellers are connected by fastening screws. The shaft consists of two sections; and the two sections of shaft are fixedly connected through a connecting shaft bolt. The shaft and the torsion spring tripods at two ends are connected by bearings. The device can realize online cleaning of a condenser, and is simple in structure, low in cost, high in stability, convenient to install and suitable for other tubular heat exchange equipment.

Description

technical field [0001] The invention relates to a matching device of a condenser, in particular to a cleaning device for a condenser based on the turbulence effect of an impeller. Background technique [0002] Condenser is an essential heat exchange equipment in a thermal power plant. Its good heat exchange effect and safety performance guarantee the efficiency of the whole plant. In the process of condensation, as the temperature of the circulating water increases, the salt is continuously precipitated, forming scale and adhering to the pipe wall. As a result, the heat exchange efficiency and service life of the condenser are greatly reduced, which seriously affects the economy and safety of the whole plant. Especially in waste-to-energy and coal chemical industries, reclaimed water from sewage treatment plants and reclaimed water from our factories are usually used as circulating water. The water quality is usually poor and scaling is more serious. [0003] At present, t...
