Detailed description of the invention
In order to make it easy to understand, below in conjunction with accompanying drawing, the utility model will be further described.
Referring to Fig. 1, layout schematic diagram for a kind of boiler blow-off water treatment facilities for dry quenching system that this utility model provides, what the boiler blow-off water treatment facilities that this utility model provides included being sequentially communicated determines row's flash vessel 1, cooler 2 and water tank 3, surely the water inlet arranging flash vessel 1 is connected with the sewage draining exit of boiler (not shown), the outlet of water tank 3 is connected with the water sealed tank water inlet manifold 14 of coke dry quenching furnace, and is provided with booster pump 4 between water tank 3 and water sealed tank water inlet manifold 14.
Referring to Fig. 1, boiler blowdown water enters cooler 2 after surely arranging flash vessel 1, and recirculated cooling water is entered cooler 2 by cooling water inlet pipe 8 and carries out heat exchange with boiler blowdown water, and the boiler blowdown water after cooling enters water tank 3 and is collected.After intensified pump 4 pressurization of boiler blowdown water in water tank 3, being delivered to the water sealed tank water inlet manifold 14 being positioned at coke dry quenching furnace charging apparatus platform, then boiler blowdown water enters coke dry quenching furnace water sealed tank 6 from water sealed tank the first water inlet 11 and water sealed tank the second water inlet 13.When coke dry quenching furnace water sealed tank 6 water level is too high, water sealed tank overfall 12 overflow.
In the particular embodiment, water tank 3 can arrange overflow pipe (not shown) near tip position, when water level is too high in water tank 3, can pass through overflow pipe automatic overflow.For convenient management, in water tank 3, water level can cause Central Control Room by liquidometer teletransmission.
In order to be stored by the boiler blowdown water being delivered to coke dry quenching furnace charging apparatus platform by booster pump 4, in the present embodiment, being provided with water sealed tank balanced reservoir 5 between water sealed tank water inlet manifold 14 and booster pump 4, water sealed tank balanced reservoir 5 is positioned at the charging apparatus platform of coke dry quenching furnace.Meanwhile, being provided with liquid level relay 9 in water sealed tank balanced reservoir 5, liquid level relay 9 electrically connects with booster pump 4.By regulating the ball float angle of the liquid level relay 9 of water sealed tank balanced reservoir 5, control coke dry quenching furnace water sealed tank 6 water level and maintain an equal level mutually with water sealed tank overfall 12 lower limb, it is ensured that the safe and stable operation of coke dry quenching furnace water sealed tank 6.
Referring to Fig. 1, in the present embodiment, boiler blow-off water treatment facilities also includes being arranged at the compressed air inlet pipe 10 that the outer comb 7 of the sewer determined between row's flash vessel 1 with cooler 2 is connected and the standby water inlet pipe 15 of water sealed tank with water sealed tank water inlet manifold 14.
When coke dry quenching furnace water sealed tank 6 needs to stop supplying water, boiler blowdown water carries out outer row by the outer comb 7 of sewer；When the blocking of coke dry quenching furnace water sealed tank 6 water inlet pipe or current are not smooth, water inlet pipe is purged by the compression air imported by compressed air inlet pipe 10；When depletion occurs in system jam coke dry quenching furnace water sealed tank 6, coke dry quenching furnace water sealed tank 6 is carried out emergence compensating water process by the standby water inlet pipe 15 of water sealed tank by dry quenching system cooling water.
When boiler blowdown water being guided in the water sealed tank of coke dry quenching furnace by boiler blow-off water treatment facilities of the present utility model, in order to avoid booster pump 4 that cavitation operationally occurs as far as possible, boiler blow-off can be water-cooled to less than 80 DEG C by cooler 2, is generally cooled to 50 DEG C～80 DEG C.
