Description
Technical field
The present invention relates to a kind of spinning clean catch device; Particularly a kind of spinning clean catch glueballs device of the spinning cleaning of the collection of glueballs and maintenance glueballs collecting net in the water-cooled condenser of power station rubber ball cleaning system, and a kind of spinning clean catch foreign material device of the spinning cleaning of the filtration of the foreign material in the cooling water in the cold source system of water-cooled power station and maintenance foreign material screen pack.
Background technology
The be in operation problem of the long-pending dirty fouling of ubiquity of water-cooled condenser of power station; And to the thermal efficiency of unit with very important influence is arranged equipment life; Therefore; At present general adopt in the heat exchanger tube glueballs to clean or heat exchanger tube in insert online modes such as spinner member and carry out scale removal and antiscale, reach purpose energy-saving and cost-reducing and that prolong the Acceptable life of equipment.
Glueballs for condenser cleans, and one of its critical piece is ball collecting device (perhaps being called ball screen).Ball collecting device commonly used can be divided into 2 kinds, (1) fixed taper ball screen according to the shape of ball screen; (2) electronic movable screen ball screen comprises the movable screen ball screen of one-board, V-type activity screen ball screen and reverse V-shaped movable screen ball screen.Fixed taper ball screen simple in structure, cost is lower, but its ball collecting device screen is stiff, can not carry out backwash, only is adapted to cooling water quality occasion preferably.Electronic movable screen ball screen, its filter screen moving/when rotating owing to need sealing device, drive unit, control device etc., structure is complicated.The ball collecting device of the movable screen of band is after operation a period of time, and screen is easy deformation under the washing away of water, causes gap increase between screen and tube wall and screen and the screen, and a part of glueballs spills from the gap, and ball collecting rate descends.The turning cylinder of screen and transmission device steep for a long time and in water, can get rusty or be mingled with, and possibly cause screen to rotate in place, and also can cause ball collecting rate to descend.The present movable screen ball screen that cleans of the glueballs of the condenser ubiquity problem with the collecting effect difference of level installation that tilts also; A large amount of glueballs is piled up in structure some the non-exit of taking out at ball screen when inclination and level installation that mainly is movable screen ball screen easily, and ball collecting rate is generally very low even almost can not receive ball.
For the water-cooled condenser of power station, no matter be closed circuit cooling system or open cooling system, inevitable some foreign material that exist in its cooling water.In order to guarantee the scale removal and the antiscaling effect of condenser on-line cleaning apparatus for eliminating sludge, need secondary filter be installed in water-cooling system (usually at the condenser cooling water inlet pipeline) usually.Present disclosed secondary filter structure has two kinds of fixed and electric rotary-types, but some problems of ubiquity or not enough, and mainly being that web-roll core is fixing like: fixed shortcoming can not rotate, clear up dirt weak effect, mesh and very easily stop up etc.; The shortcoming of electric rotary-type mainly is that complex structure is fragile, water resistance is bigger, the cleaning dirt weak effect of the dirt (plastic sheeting, weeds etc.) stronger to adhesion etc.
In sum; No matter be the ball collecting device (ball screen) of glueballs in the rubber ball cleaning system for steam condenser in the cold source system of water-cooled power station at present; Still all there is certain deficiency in the secondary filter in the cold source system of water-cooled power station, thereby influences its effect with energy-saving and cost-reducing.
Summary of the invention
To the problems referred to above; The purpose of this invention is to provide a kind of spinning clean catch device that utilizes the mobile mechanical energy (pressure reduction and kinetic energy) of pending fluid media (medium) as rotary power; This device is installed in the pipe-line system of pending medium; Utilize mechanical energy that pending fluid media (medium) flows as rotary power, under the effect of flowing of pending fluid media (medium), do not need additionaling power (like electric power) can make a kind of rotation in this device wash away and scrape mechanism's generation spinning; Thereby make in the pending fluid media (medium) treat gleanings perhaps/with foreign material through behind the cone-shaped collection net filtration; And scrape under the acting in conjunction of dashing, brush, scraping of mechanism washing away of spinning, be easy to reach conical collecting net the rear end the collection mouth and be drawn out of, keep the cleaning of collecting net simultaneously.For the ball screen of glueballs in the water-cooled condenser of power station rubber ball cleaning system, the effect of spinning clean catch device is: the glueballs of collecting in the cooling water is delivered to the cleaning that ball collector also keeps collecting net simultaneously by the suction of glueballs water pump then; For the secondary filter in the cold source system of water-cooled power station, the effect of spinning clean catch device is: foreign material in the collection cooling water and blowdown also keep the cleaning of collecting net simultaneously.
A kind of spinning clean catch device of the present invention has following advantage: (1) need not additionaling power, and rotational structure is stressed little, and is simple in structure, is not easy to break down, and the life-span is long.(2) spinning structure can remain the cleaning of collecting net, is difficult for stopping up.(3) water resistance is little, than the water resistance reduction 20%-50% even more of existing electronic movable screen ball screen and electric rotary-type secondary filter.(4) adopt fixed conical collecting net, be not easy to produce distortion, damaged, run and leak phenomenon, simultaneously since spinning wash away the acting in conjunction of dashing, brush, scraping of scraping mechanism, collecting effect is good.Therefore, glueballs ball screen in as rubber ball cleaning system for steam condenser, it is effective to receive ball, not jumping ball; When as secondary filter, it is strong and adaptive faculty is strong to collect the ability of foreign material; (6) operation and easy to maintenance can move control, can freedom from repairs in normal course of operation.(7) glueballs ball screen in as rubber ball cleaning system for steam condenser, it is little that it gets rid of the water yield that foreign material take away, and has only below 30% of common secondary filter usually.
