Description
Technical field
The utility model relates to a kind of waste heat boiler, specifically disposes the waste heat boiler of Novel water cooling wall roof tube structure through walls.
Background technology
Boiler is as a kind of heat-exchange apparatus, during work, must under subnormal ambient, move and possess good sealing property, otherwise boiler internal is very easy to suck extraneous air, thereby under the effect of crossing of hot and cold air, produce that exhaust gas volumn in the burn into stove of water-cooling wall increases, system power load strengthens and the problem such as combustion conditions variation, even also can reveal because malleation in stove causes flue gas, cause serious environmental pollution accident.
Existing boiler furnace structure (as shown in Figure 5), not only comprise the outer wall water-flow circuit being formed by roof tube 2, roof tube header 5, also be provided with independent internal water closed circuit, comprise partition wall water-cooling wall 4, be positioned at the partition wall header 1 of roof tube 2 tops and the water-cooling wall tube connector 3 that connects partition wall water-cooling wall and partition wall header; The high-temperature flue gas producing during boiler work is respectively by discharging from outlet after the first flue 6, the second flue 7, the 3rd flue 8, the 4th flue 9.
In the junction of roof tube and partition wall water-cooling wall tube connector, roof tube is necessary for partition wall water-cooling wall tube connector allows pipe (shape that inclination is bent upwards) can vertically pass through roof tube to guarantee partition wall water-cooling wall tube connector.For solving the problem of pipe position seal failure and roof tube stiffness degradation of allowing, must allow pipe position add seal closure and use girder steel 10 to support roof tubes.
But said structure is comparatively complicated, design, construction and maintenance all have more highly difficult, therefore need further solution.
Utility model content
The purpose of this utility model is the deficiency overcoming in above-mentioned background technology, the waste heat boiler of a kind of Novel water cooling wall roof tube structure through walls is provided, when the water-cooling wall roof tube structure in this waste heat boiler should be able to make partition wall water-cooling wall tube connector and partition wall header reliable connected, effectively guarantee roof tube sealing and rigidity, and simple in structure, easy to maintenance.
The technical scheme that the utility model provides is: the waste heat boiler with Novel water cooling wall roof tube structure through walls, comprise three vertical fin panel casing passages and a flue gas flow channel that vertical gas pass forms, the top of water-cooling wall passage and flue gas flow channel is the water-cooling wall ceiling that a plurality of roof tubes that are arranged parallel to each other form; In described three water-cooling wall passages, between first passage and second channel, be vertically to arrange by a plurality of water screen tubes the partition wall water-cooling wall forming; The top of water screen tube also communicates with horizontally disposed partition wall header by several water-cooling wall tube connectors that up stretch; It is characterized in that: on the both sides sidewall of described partition wall header, be shaped with the multipair and matched through hole of roof tube external diameter, described a plurality of roof tubes intert one by one respectively and are positioned in above-mentioned through hole, the equal welded seal of the seam areas of roof tube and through hole.
The axis of described partition wall header is substantially vertical with the axis of roof tube.
The beneficial effects of the utility model are:
The utility model is by being arranged on partition wall header and roof tube in same plane, allow partition wall header directly wear and be positioned on roof tube, can not only make like this partition wall water-cooling wall and roof tube still as two independent water-flow circuits, sealing property and the intensity that can also keep roof tube simultaneously, without adding seal closure and buckstay, thoroughly solved roof tube because allowing seal failure problem that pipe causes and the problem of stiffness degradation; In addition, of the present utility model relatively simple for structure, construction is all more convenient with maintenance.

The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
Embodiment shown in Fig. 5 is the heat exchange section structural representation (waste incineration wherein is partly omitted) of incinerator waste heat boiler; Comprise three vertical fin panel casing passages (comprising the first flue 6, the second flue 7, the 3rd flue 8) and a flue gas flow channel (the 4th flue 9) that vertical gas pass forms, the top of water-cooling wall passage and flue gas flow channel is the water-cooling wall ceiling that a plurality of roof tubes that are arranged parallel to each other 2 form; Described three water-cooling wall passages form (each partition wall water-cooling wall is arranged and formed by a plurality of vertical water screen tubes) by 2 partition wall water-cooling wall intervals, the water screen tube in the partition wall water-cooling wall 4 between first passage and second channel wherein, also the several water-cooling wall tube connectors 3 that up stretch by top communicate with horizontally disposed partition wall header 1.The high temperature carbonated drink product producing in partition wall water-cooling wall is flowed in partition wall header and is formed internal water closed circuit by water-cooling wall tube connector; The high-temperature steam producing in roof tube flows in roof tube header and forms outer wall water-flow circuit; The axis of roof tube is basically perpendicular to the axis of partition wall header; In addition, shape α at a certain angle (as shown in Figure 2) between roof tube and horizontal plane, this angle is generally 2-10 degree.
Improvements of the present utility model are:
Partition wall header is moved down, and on the sidewall of both sides, be shaped with multipair through hole 1-1, the external diameter fit of the internal diameter of through hole and roof tube, a plurality of roof tubes intert respectively one by one in above-mentioned through hole; For guaranteeing the sealing of partition wall header, the equal welded seal of seam areas of roof tube and through hole.Therefore, the utility model is guaranteeing that two water-flow circuits are still independent operating in the situation that, not only improved the rigidity of roof tube, reinforcement material and operating expenses (without using girder steel, reinforcing) have been saved, and guaranteed the sealing property of roof tube, also without adding seal closure, avoided managing because roof tube allows the series of problems causing, obtained reasonable effect.
The operation principle of this embodiment is: the flue gas producing after the waste incineration on fire grate, tube connector (being furnished with the gap that allows flue gas to pass through between tube connector) by the first flue 6 outlets directly enters the second flue 7, through the separation of heat exchange and flying dust, the ash bucket of cooling flue gas through the second flue bottom enters the 3rd flue 8; In third channel, arranged successively convection current evaporimeter, high temperature superheater, medium temperature overheater and low temperature superheater, flue gas enters the 4th flue on the 3rd flue top, by discharging after the economizer in four-way and smoke air preheater.The saturated vapor of separating in each heat-exchanger rig enters Turbo-generator Set successively and generates electricity after low temperature superheater, medium temperature overheater, high temperature superheater.
