Description

Slag cooler

Technical field:

The utility model relates to a kind of slag cooler of giving the slag cooling usefulness of power plant circulating fluidized bed boiler.

Background technology:

Do support with the reinforcing bar that is spirally wound on the inwall between the inside and outside barrel of the cylindrical shape of existing slag cooler, make between two walls and form cooling water sandwich, because cooling water is limited by reinforcing bar, can only flow along spirality channel, the flow velocity of water is slow, flow is little, does not satisfy the needs of slag cooling, the slag temperature of entering from slag inlet is 1100-1200 ℃, the slag temperature that comes out from the slag cooler slag output end is up to 350-400 ℃, also needs through nature cooling just can entruck and carry away contaminated environment; And because the cooling water flow velocity is slow, the water often slag entrance point of no show slag cooler is just vaporized, and the slag cooler inwall is burnt out, and what influence was produced normally carries out.

Summary of the invention:

Technical problem to be solved in the utility model provides a kind of slag good cooling effect, inwall is difficult for the slag cooler that quilt is burnt out.

Above-mentioned purpose is achieved in that columnar stack shell comprises inner tube wall, outer tube wall, be cooling water sandwich between the inside and outside barrel, the inner tube wall inboard is welded with leads the slag sheet by helical pattern, leading on the inner tube wall between the slag sheet of adjacent helical pattern is welded with several dividing plates, dividing plate and lead between the slag sheet and to form several little lattice, stack shell one end has slag inlet, and the other end is a slag output end; Be fixed with the track of bipassage ring around stack shell on the stack shell outer wall, track places on the track support roller of base for supporting, and hinge wheel also is housed on the outer wall, and hinge wheel is connected with the drive sprocket of reductor by chain, intake the in addition in addition water pump and the water pump that draws water; Unlike the prior art: in the cylindrical shape stack shell, establish partition wall between the outer tube wall, cooling water sandwich is divided into inside and outside two-layer, partition wall with in, be welded with several between the outer tube wall and support post, in partition wall one end and the slag cooler slag output end, the outer tube wall end is on same vertical line, be equipped with respectively between inner tube wall and the partition wall and between partition wall and the outer tube wall annular in, outer end socket, in the partition wall other end and the slag cooler slag inlet end, certain distance is left in the outer tube wall end, in the cooling water sandwich, outer in this connection, the water inlet water pump has pipeline to be connected with the interior ring of water knockout drum, on the ring several delivery ports are arranged in the water knockout drum, in the water knockout drum ring outside with in establish annular water chamber the outer shroud slipper seal be connected, there are several outlet pipes to be connected on the outer shroud, the internal layer of annular water chamber with the stack shell cooling water sandwich is communicated with interior end socket; The water pump that draws water has pipeline to be connected with the interior ring of water collector, on the ring several water inlets are arranged in the water collector, in the water collector ring outside with in establish annular water chamber the slipper seal of water collector outer shroud be connected, there are several water inlet pipes to be connected on the outer shroud, the annular water chamber of water collector outer shroud is communicated with the skin of stack shell cooling water sandwich with outer end socket.

The utility model has the advantages that: because the cooling water sandwich space is big, it is without hindrance to flow, so good cooling effect, according to test, the slag temperature that the slag cooler slag output end is discharged is below 100 ℃, directly entrucking, reduce environmental pollution, improved operating efficiency, slag cooler slag input end is difficult for being burnt out, and has prolonged service life.
