Description
Technical field
The utility model belongs to the petrochemical technology field, relates generally to a kind of dismountable shell of pipe type waste heat boiler with according with the composite ceramics protective casing.
Background technique
In modern industry, waste heat boiler is to reclaim general, the most maximum a kind of technical equipment that heat energy is used in the energy conservation, and its promotion and application play a part very important to the saving of the energy.The tube side high temperature side medium of waste heat boiler mostly is vapor plume, process gas etc., and its temperature is higher, how about 1000 degrees centigrade, have in addition reached 1400 ℃, the heat insulation protection of suction side tube sheet and heat exchanging tube becomes the key problem in technology of waste heat boiler.Because what can under high pressure resist high temperature like this in the current material is rare.Prior art adopts at the heat-resisting heat insulation layer of tube sheet side coated non-metallic more, and inserts a protective casing at the heat exchanging tube entrance point.The protective casing prior art adopts metal or corundum ceramic more, and is at high temperature ceramic in the majority.But the deficiency that the corundum ceramic sleeve pipe in use reflects is also more, and excessive with the temperature difference that it inserts in the heat exchanging tube as porcelain bushing temperature in the nonmetal heat-resisting heat insulation layer that the tube sheet side applies, corundum ceramic thermal shock performance deficiency causes thermal shock cracked; Structural design fails to solve porcelain bushing extruding such as temperature difference stress that the external world passes over and distortion, and distortion is inharmonious between porcelain bushing, the nonmetal refractory insulating layer of tube sheet side and the tube sheet causes damage; Porcelain bushing damages the back and is difficult for problems such as replacing.Because protective casing is the key components and parts of this equipment, its usability has a strong impact on device security and working life.
Summary of the invention
The purpose of this utility model is to propose dismountable shell of pipe type waste heat boiler composite ceramics protective casing, improves intensity, the thermal shock resistance of protective casing, uses more convenient.
The utility model is finished the technological scheme that its invention task taked:
A kind of dismountable shell of pipe type waste heat boiler composite ceramics protective casing; has a composite ceramics inner sleeve; the composite ceramics inner sleeve is a reducer pipe; the composite ceramics inner sleeve place that inserts in the high temperature side plate tube sheet heat exchange hole is provided with annular groove; be provided with ceramic fiber paper in the annular groove; the place is provided with ceramic fibre mat at composite ceramics inner sleeve reducing; in the extra heavy pipe end of described composite ceramics inner sleeve two boss are set; boss clamping mutually on two boss and the composite ceramics outer sleeve inner wall; constitute the composite ceramics inner sleeve; the snap ring structure of composite ceramics outer sleeve is at the composite ceramics inner sleeve; be provided with the ceramic fiber ring that seals between the composite ceramics outer sleeve.
The utility model adopts technique scheme to have following beneficial effect:
1, operational safety height owing to adopted composite ceramics, is compared its impact toughness, bending strength, thermal shock resistance and all is significantly improved with corundum ceramic.In addition, be provided with a ceramic fiber ring, be used for the sealing between the composite ceramics internal and external casing, reliability is significantly improved once more at special position.
2, change conveniently, adopted the snap ring structure,, can realize the replacing of inner sleeve easily by this snap ring.
3, with low cost, convenient processing and manufacture.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, composite ceramics outer sleeve, 2, the ceramic fiber ring, 3, the composite ceramics inner sleeve, 4, insulated lining, 5, ceramic fibre mat, 6, ceramic fiber paper.
Embodiment
In conjunction with the accompanying drawings the utility model further is illustrated:
As shown in Figure 1, a kind of dismountable shell of pipe type waste heat boiler composite ceramics protective casing has a composite ceramics inner sleeve 3 and composite ceramics outer sleeve 1; Composite ceramics inner sleeve 3 is a reducer pipe, the composite ceramics inner sleeve place that inserts in the high temperature side plate tube sheet heat exchange hole has annular groove, be provided with ceramic fiber paper 6 in the annular groove, annular groove can prevent that ceramic fiber paper 6 from being washed away, the place is provided with ceramic fibre mat 5 at composite ceramics inner sleeve reducing, in the extra heavy pipe end of described composite ceramics inner sleeve two boss are set, boss clamping mutually on two boss and the composite ceramics outer sleeve inner wall, constitute composite ceramics inner sleeve 3, the snap ring structure of composite ceramics outer sleeve 1, at composite ceramics inner sleeve 3, be provided with the ceramic fiber ring 2 that seals between the composite ceramics outer sleeve 1, described ceramic fiber ring 2 is made by aluminum silicate fiber, possess good heat-shielding performance and resistance to high temperature, it has been shaped as certain thickness ring.
During equipment operation; high-temperature technology gas or vapor plume enter in the heat exchanging tube by composite ceramics inner sleeve 3; because insulated lining 4, ceramic fibre mat 5, ceramic fiber paper 6 and composite ceramics internal and external casing 1 all are good thermal-protective materials; thermal conductivity is very low; can effectively prevent heat exchanging tube and tube sheet overtemperature, play the effect of protection tube sheet and heat exchanging tube.
Under complex working condition, owing to medium flow or other reasons causes 3 vibrations of composite ceramics inner sleeve to be ruptured, only need this moment earlier ceramic fiber ring 2 to be taken out, then composite ceramics inner sleeve 3 is rotated to an angle gently, can from composite ceramics outer sleeve 1 inside it be taken out easily.
Claims (1)
1. a dismountable shell of pipe type waste heat boiler composite ceramics protective casing has a composite ceramics inner sleeve (3) and composite ceramics outer sleeve (1); Described composite ceramics inner sleeve (3) is a reducer pipe, the composite ceramics inner sleeve place that inserts in the high temperature side plate tube sheet heat exchange hole has annular groove, be provided with ceramic fiber paper (6) in the annular groove, be provided with ceramic fibre mat (5) at the reducing place of composite ceramics inner sleeve (3), it is characterized in that: two boss are set in the extra heavy pipe end of composite ceramics inner sleeve (3), boss clamping mutually on two boss and composite ceramics outer sleeve (1) inwall constitutes the snap ring structure of composite ceramics inner sleeve (3), composite ceramics outer sleeve (1); Between composite ceramics inner sleeve (3), composite ceramics outer sleeve (1), be provided with the ceramic fiber ring (2) that seals.
