The specific embodiment
A kind of residual heat collection module embodiment being arranged in sintering machine main smoking road, referring to Fig. 1, Fig. 2 Fig. 3, and Fig. 4, described module comprises a casing 1, described casing has a flue section 1-1, the two ends of flue section are respectively equipped with the connector being connected with main smoking road, wherein, described casing also has a heat exchange segment 1-2, the heat exchange segment that runs through casing is provided with heat pipe tube bank 2 to flue section, the flue gas in main smoking road enters through heat pipe tube bank and flows out from flue section connector port of export 1-1-2 from flue section connector arrival end 1-1-1, on the relative sidewall of described heat exchange segment, be respectively arranged with fluid inlet 1-2-1 and fluid issuing 1-2-2.
In embodiment; as shown in Figure 1; in order to protect heat pipe tube bank not to be subject to the damage of flue dust; many flue gas guide posts 3 are arranged side by side at described flue section connector arrival end; the cross section of described guide post is triangle; wherein; two face 3-1 and the 3-2 of described triangular cross section guide post meet to smoke gas flow Inbound; it is that angle is the face of two of 30 degree to 60 degree that described guide post is met to two faces of smoke gas flow Inbound; the best is the face of two of 45 degree, is provided with reinforcement 3-3 between two faces.Be provided with flue dust collecting mouth 1-3 in the bottom surface of casing.
In embodiment, to wash away and cause heating surface wear in order further to have reduced by dust opposite heat tube heating surface in main smoking road, described guide post is arranged on described flue section smoke inlet end perpendicular to ground, between adjacent two triangle guide posts, rear side is provided with gas baffle 4, leaves flue gas circulation gap between gas baffle and two guide posts.Flue dust can fall into tank floor along guide post side wall surface and gas baffle.Have flue dust collecting mouth in tank floor, every a period of time, mouth is opened to collection, and then shut, this kind of structure prevented or at least reduced by dust opposite heat tube heating surface in main smoking road and washed away and cause heating surface wear and damage because low temperature acid corrosion causes heat pipe heating surface, and the system that guaranteed is moved without potential safety hazard.
In embodiment, casing is general frame structure, comprises housing steel construction, insulation material, inner building materials, and flue section connector arrival end and the connector port of export are hemispherical dome structural members and are provided with flange.
Above-mentioned residual heat collection module is one of sub-assembly being applied to by waste heat boiler, and this sub-assembly comprises province's coal gas, evaporimeter, superheater, and it arranges how much adjust flexibly according to sintering machine size and technique, all adopt heat-pipe heat exchanger.This heat exchanger directly inserts sintering machine main and takes out in dust-removing flue, and flue resistance loss is little, and sintering process is had no adverse effects.
Because casing is at the main ash bucket that gathers dust that is provided with of taking out dust-removing flue bottom, in equipment, heat-transfer surface depositing dust space communicates with the ash bucket that gathers dust, and the stifled phenomenon of dust stratification ash can not occur for hot fume side casing and the tube bank of boiler heating surface heat pipe; The protection against erosion flue gas guide post device of setting up, can effectively reduce washing away of dust contained flue gas opposite heat tube tube bank, and this structural drag is little simultaneously, changes little to the blast in main smoking road.
