Abstract
The utility model relates to a new built-in type smoke purifying chamber for a layered combustion stove, which is arranged in a high-temperature zone between stove walls of two rear sides of a stove chamber. The utility model is composed of a cylindrical smoke gas rotary passage, wherein the cylindrical smoke gas rotary passage is separated from a convection bank zone by a wall and is separated from a stove chamber by a wall, and both ends of the cylindrical smoke gas rotary passage are respectively connected with the separation walls between the two separation walls. Both side walls of the middle part of the cylindrical smoke gas rotary passage are respectively provided with an upper and a lower smoke gas rotary inlets; the purifying chamber is provided with two smoke gas inlets respectively arranged on the upper parts of both sides of the separation wall between the cylindrical smoke gas rotary passage and the furnace chamber. The utility model has the advantages that smoke gas enters the cylindrical smoke gas rotary passage after forming rotation by the flowing direction of single smoke gas to form smoke gas secondary rotation for purification and heat exchange; the rotational strength is high and uniform, the residence time is long, and the dust removing and the heat exchange are ideal.
Description
The utility model relates to the boiler combustion technology field, particularly relates to gas cleaning chamber in a kind of grate furnace.
The patent No. of using is 94201371.9 grate furnace whirlwind burning chamber at present, have only a side smoke inlet and an exhanst gas outlet, the flue gas rotation forms by single flue gas flow direction, spin intensity is weak, rotation is inhomogeneous, and the holdup time is short, and dust-collecting and heat exchanging is undesirable, the large-tonnage boiler, whirlwind outlet bore strengthens, and is difficult for processing, and bore is fragile.
The purpose of this utility model provides gas cleaning chamber in a kind of novel grate furnace, with a little less than solving existing grate furnace whirlwind burning chamber spin intensity, rotation is inhomogeneous, the holdup time is short, dust-collecting and heat exchanging is undesirable, large-tonnage boiler whirlwind outlet bore is difficult for processing flimsy deficiency.
The technical solution of the utility model is, the clean room is arranged between the furnace wall of both sides, burner hearth rear portion in the high-temperature region, it by with convection bank separate wall and with the burner hearth partition wall and between above-mentioned two partition walls two ends form with the cylindrical shape flue gas rotational path that described partition wall links to each other respectively, two side, cylindrical shape flue gas rotational path middle part has on one respectively, the inlet of two flue gases rotation once, clean room design have two smoke inlets respectively with burner hearth partition wall both sides above, clean room's exhanst gas outlet design separates on the wall with the convection bank that convection bank separates the continuous end corresponding position of wall at cylindrical shape flue gas rotational path, and ash port is arranged at the bottom, clean room.Flue gas after forming rotation by the single flow direction of flue gas between described two partition walls, relatively respectively from two side one, cylindrical shape flue gas rotational path middle part, the inlet of two flue gases rotation once enters and makes the tangential convection current of flue gas form secondary rotation purification heat exchange the cylindrical shape flue gas rotational path in cylindrical shape flue gas rotational path.
The utility model compared with the prior art, because clean room's design has two smoke inlets, have on one with the both sides, middle part, the cylindrical shape flue gas rotational path of the inlet of two flue gases rotation once, its advantage is that flue gas is after forming once rotation by single flue gas flow direction, from two side one, cylindrical shape flue gas rotational path middle part, the inlet of two flue gases rotation once enters in the cylindrical shape flue gas rotational path, in cylindrical shape flue gas rotational path, form the rotation of flue gas secondary by tangential relative current and purify heat exchange, first flue gas rotation and secondary rotation move towards to be orthogonal 90 ° of angles, the spin intensity height, rotation evenly, holdup time is long, dust-collecting and heat exchanging is more satisfactory, and flue gas shunting passes through from cylindrical shape two side flue gas rotation inlet, its each rotation bore can dwindle one times, and is easy to manufacture, not fragile.
