Description
Technical Field
The invention relates to the technical field of condensers, in particular to a condenser cleaning device.
Background
The condenser is heat exchange equipment for driving steam turbine to change exhausted steam into condensed water after acting, and is composed of condenser, condensed water pump, air extractor, circulating water pump, connecting pipeline and accessories, and is main auxiliary equipment for condensing steam turbine, and is mainly used for power generation of power plant.
In the long-time use process of the condenser, the water for cooling is recycled and repeatedly used, and is continuously evaporated and concentrated, so that the salt content is gradually increased, circulating water flows in a steel pipe of the condenser, a laminar boundary layer is closely attached to the pipe wall, the flow speed is very slow, indissolvable or slightly soluble salts generally have fixed crystal lattices and abnormal solubility, and inorganic salting out in the circulating water is retained on the inner wall of the pipe to form inorganic salt dirt; because the water intake source of the circulating water comes from natural water, some sediment possibly enters the condenser, and the sediment and the inorganic salt are compounded together to form compound dirt of inorganic salt and sediment; under certain conditions, the sediment content of the circulating water is higher, and sediment dirt is formed on the inner wall of the condenser pipe at the moment; in addition, when circulating water quality treatment is improper, can lead to some microorganism, algae to breed at condenser heat exchange tube inner wall, this just forms living beings dirt, condenser heat exchange tube bank scale has not only caused clean coefficient to reduce, the heat exchange efficiency reduces, still can cause to give birth to electrochemical corrosion when serious, the catch water quality of pollution unit, influence unit safety economy operation, in time effectively clear tube bank scale, it is obvious to have apparent energy-conserving benefit, at present mainly use the abluent mode of rubber ball, through adding the sponge rubber ball that diameter is equivalent with the heat exchange tube mouth of pipe diameter to the condenser hydroecium, lean on circulating water velocity to scrub the heat exchange tube inner wall, keep the inside cleanness of condenser.
However, the mode of cleaning the rubber ball belongs to passive cleaning, the cleaning effect depends on the flow rate of circulating water, the rubber ball is difficult to reach in certain dead angle areas inside the condenser, and when the condenser is cleaned to a rear position, as more dirt is adhered to the surface of the rubber ball, the surface of the rubber ball tends to be smooth, the adhesion degree of the rubber ball to water scale is reduced, so that the cleaning effect of the rear section of a condenser pipeline is reduced compared with that of the front section, the cleaning effect is limited to a certain extent, the cleaning effect is limited by factors such as unstable ball receiving rate, uneven underwater distribution of the rubber ball, high failure rate of a pipeline system and the like, the online descaling efficiency is low, the high-pressure water adopted in overhauling is used for flushing, the cleaning effect on compact inorganic salt dirt is limited, in addition, once the system is put into operation, sediment dirt is quickly deposited, the cleaned out of the cleaned water scale occupies some normal working time of the condenser, and therefore the condenser cleaning device is provided in an operation state.
