A kind of water-cooling screen partition wall membrane wall of one side exposure, comprise front water-cooled lower header, rear water-cooled lower header, before and after water-cooling wall upper collecting chamber and by water-cooling system prepattern wall, membrane wall after water-cooling system, the water cooled membrane wall that the right membrane wall of water-cooling system and the left membrane wall of water-cooling system are formed, wherein: it also comprises at least two water-cooling screen partition walls, described water-cooling screen partition wall is by membrane wall on the left of partition wall, membrane wall on the right side of partition wall, partition internal-film formula wall, two partition wall lower headers and two partition wall upper collecting chamber compositions, on the left of partition wall, the lower end water inlet of membrane wall is connected with the delivery port of a partition wall lower header, on the right side of partition wall, the lower end water inlet of membrane wall is connected with the delivery port of another partition wall lower header, on the left of partition wall, the upper end delivery port of membrane wall is connected with the water inlet of a partition wall upper collecting chamber, on the right side of partition wall, the upper end delivery port of membrane wall is connected with the water inlet of another partition wall upper collecting chamber, the lower end water inlet of partition internal-film formula wall is connected with the delivery port of front water-cooled lower header or rear water-cooled lower header, the upper end delivery port of partition internal-film formula wall is connected with the water inlet of front and back water-cooling wall upper collecting chamber, after water-cooled partition wall is arranged on water-cooling system prepattern wall and water-cooling system, membrane wall forms shunt circuit with water cooled membrane wall.
On the right side of described partition wall, on the left of membrane wall and partition wall, membrane wall to be provided with through place at burner hearth buckstay and to allow tubular construction.
Described water-cooling screen partition wall is provided with wear prevention material and pipe structure in the junction of CFBB emulsion zone and dilute-phase zone.
After described water-cooling screen partition wall and water-cooling system prepattern wall and water-cooling system, membrane wall junction arranges sealing chock.
The utility model adopts above technical scheme, water cooled membrane wall arranges at least two water-cooling screen partition walls, solves existing recirculating fluidized bed water cooled membrane wall and have that radiation heating-surface deficiency, water-cooling screen hydrodynamic force reliability are low, boiler startup time water-cooling system power consumption and the large technical problem of energy consumption.Therefore, compared with background technology, the utility model has that radiation heating-surface is large, water-cooling screen partition wall hydrodynamic force reliability is high, boiler startup time the water-cooling system power consumption advantage little with energy consumption, and low cost of manufacture, is convenient to installation.
