Abstract

The invention discloses a condenser heat transfer tube cavitation jet cleaning device and a cleaning method thereof. The condenser heat transfer tube cavitation jet cleaning device comprises a condenser water inlet chamber; the gas condensing pipe plate is fixedly arranged on the left side wall of the condenser water inlet chamber; a plurality of condenser heat transfer pipes are arranged, and each condenser heat transfer pipe is communicated with the condenser water inlet water chamber through a condensing pipe plate; the positioning mechanism is fixedly arranged in the condenser water inlet chamber, the positioning mechanism comprises a sliding seat and a sliding block which are controlled by a two-dimensional robot positioning system, and the sliding seat is provided with the sliding block. The cavitation cone is pushed to advance through high-pressure water jet, when water flow passes through the cavitation cone, the cavitation effect is generated, dirt near the cavitation cone is cleaned away, and from the perspective of the cleaning effect, the cavitation jet cleaning effect is good, and the cavitation jet cleaning device mainly has the advantages of being efficient, safe, environmentally friendly, capable of saving energy and the like and does not damage equipment base metal.

Description

technical field [0001] The invention specifically relates to the technical field of cleaning devices for heat transfer tubes of condensers, in particular to a cavitation jet cleaning device for heat transfer tubes of condensers and a cleaning method thereof. Background technique [0002] For a long time, condenser fouling has plagued the economical, environmentally friendly and safe operation of thermal power coal-fired units. [0003] The long-term existence of dirt on the heat transfer tube of the condenser will lead to a decrease in the thermal conductivity of the heat transfer tube and an increase in thermal resistance, which will further deteriorate the vacuum of the condenser and reduce the efficiency of the steam turbine, resulting in an increase in coal consumption for power generation; at the same time, the heat transfer tube of the condenser Dirt causes cooling water flow area to decrease, flow resistance to increase, condenser circulating water pressure loss and c...
