Abstract
The utility model discloses a boiler tube plate thermal protection device which comprises a front tube plate, a refractory castable area, a porcelain sleeve and a smoke tube. The outer wall of the front section of the porcelain sleeve is provided with the refractory castable area. The outer wall of the rear section of the porcelain sleeve is connected with the smoke tube in a sleeved mode. The outer wall of the smoke tube is provided with the front tube plate. An isolating layer is arranged between the smoke tube and the front tube plate. A through hole is formed in the refractory castable area. A heat-dissipating device or a water injection through hole is formed in the through hole. The boiler tube plate thermal protection device effectively lowers the temperature of a tube head, is simple in structure, convenient to construct, safe and reliable, and prolongs the service life of a waste heat boiler greatly.
Description
Technical field
The utility model relates to field of boilers, be specifically related to a kind of boiler's tube-plate temperature barrier
Background technology
Affect the factor of waste heat boiler tube head temperature except temperature, pressure, flow, the component of high-temperature gas; outside the technological factors such as the steam pressure that waste heat boiler produces; the influence factor of mainly considering from device structure aspect is: waste heat boiler tube plate thickness; the diameter of boiler tube and wall thickness; the size of boiler tube layout and tube pitch; tubesheet lining material is selected and thickness; protective casing itself and sleeve pipe and boiler tube are asked annular space; dull gas thickness; the thermal contact resistance that tube-to-tube sheet connection is connected to form, tube sheet rear surface and just stretched out the boiling situation at the outer tube surface place of tube sheet.Traditional waste heat boiler, because do not consider these factors comprehensively, is therefore easy at high temperature be corroded, and greatly reduces its service life.
Utility model content
For the deficiency existing in prior art, the utility model object is to be to provide a kind of boiler's tube-plate temperature barrier, effectively reduces tube head temperature, and simple in structure, easy construction, safe and reliable has extended service life of waste heat boiler greatly.
To achieve these goals, the utility model is to realize by the following technical solutions: boiler's tube-plate temperature barrier, comprise front tube sheet, castable refractory district, porcelain bushing shell, chimney, described porcelain bushing shell leading portion outer wall is provided with castable refractory district, described porcelain bushing shell back segment outer wall and chimney socket-connect, described chimney outer wall is provided with front tube sheet, between described smoke pipe and front tube sheet, be provided with separation layer, described castable refractory is provided with through hole in district, is provided with heat abstractor or water filling through hole in described through hole.
As preferably, described porcelain bushing shell thickness is 3mm-7mm.
As preferably, on described front tube sheet, be provided with refractory layer.
The utility model effectively reduces tube head temperature, and simple in structure, easy construction, safe and reliable has extended service life of waste heat boiler greatly.
Accompanying drawing explanation
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
With reference to Fig. 1, this specific embodiment is by the following technical solutions: boiler's tube-plate temperature barrier, comprise front tube sheet 1, castable refractory district 2, porcelain bushing shell 3, chimney 4, described porcelain bushing shell 3 leading portion outer walls are provided with castable refractory district 2, described porcelain bushing shell 3 back segment outer walls and chimney 4 socket-connect, described chimney 4 outer walls are provided with front tube sheet 1, between described smoke pipe 1 and front tube sheet 1, be provided with separation layer, in described castable refractory district 2, be provided with through hole 5, in described through hole 5, be provided with heat abstractor or water filling through hole.
It should be noted that described porcelain bushing shell 3 thickness are 3mm-7mm.
It should be noted that on described front tube sheet 1 and be provided with refractory layer.
This specific embodiment adopts two porcelain bushing shells protection structures, effectively reduces tube head temperature, and simple in structure, easy construction, safe and reliable has extended service life of waste heat boiler greatly.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
