Abstract
The utility model relates to a dew point corrosion proofing energy-saving heating furnace lining, which is characterized in that a painting layer coated with fire cement is arranged on the inner side of the steel plate of a furnace shell, welding points of anchor nails are arranged inside the fire cement painting layer, and a refractory fiber painting layer is coated on the fire cement painting layer. The thickness of the fire cement painting layer ranges from 20 mm to 25 mm, and the thickness of the refractory fiber painting layer ranges from 100mm to 200mm. The utility model has the advantages of long service life, convenient construction, high working efficiency, fine intensity and light furnace lining weight, wherein the service lift of the utility model can reach over 10 years, while the service life of a common fiber furnace lining only ranges from 5 to 6 years.
Description
Technical field
The utility model relates to a kind of improvement of lining of tubular heater, is the energy-saving heating furnace lining of a kind of preventing corrosion of dew points, can be widely used in petroleum chemical industry and other industry.
Background technology
Traditional tubular heater is made up of brick structure or refractory concrete structure mostly, and such structure furnace lining weight is big, the thermal conductivity height, thereby the thermal efficiency of body of heater own is low, and energy consumption is big, and construction is got up also pretty troublesome.The heating furnace lining replaced as ceramic block, ceramic blanket or ceramic fibre sprayed on material gradually by novel aluminum sulfate fibrous material in the last few years.
Refractory fiber lining is through for many years use some weak point still, good energy-conserving effect, but, exist the dew point corrosion problem, because the high temperature anchoring piece of hanging corrodes from root, pad exposes easily and comes off after a while, thereby causes furnace lining to come off gradually, has shortened the service life of heating furnace greatly.
Summary of the invention
Be to solve the problem that prior art exists, the purpose of this utility model provides the energy-saving heating furnace lining of a kind of preventing corrosion of dew points, and the structure of this heating furnace lining is improved, and its long service life, can effectively prevent dew point corrosion at good energy-conserving effect.
The utility model adopts following technical scheme to realize:
The energy-saving heating furnace lining of preventing corrosion of dew points is coated with the refractory cement spraying bed of material in stove skin steel plate inboard, the anchor studs pad is positioned at the refractory cement spraying bed of material, also is coated with the refractory fiber spraying bed of material on the refractory cement spraying bed of material.
The thickness of the refractory cement spraying bed of material is 20-25mm; The thickness of the refractory fiber spraying bed of material is 100-200mm.
The utility model has the advantages that: long service life, can reach more than 10 years, the service life of general fibre furnace lining is 5-6 only; Easy construction, high efficiency, intensity is good, and furnace lining is in light weight.
Description of drawings
Fig. 1 is the structural representation of the energy-saving heating furnace lining of preventing corrosion of dew points.
1-refractory fiber spraying material 2-stove skin steel plate 3-anchor studs 4-V type anchor studs 5-refractory cement spray paint
The specific embodiment
See Fig. 1, the energy-saving heating furnace lining of preventing corrosion of dew points, the work progress of this structure is: at first anchor studs 3 and V-type anchor studs 4 are welded on the stove skin steel plate on 2, then with heavy flush coater spraying one deck refractory cement spray paint 5, its thickness is 20-25mm, and then on refractory cement spray paint 5, with refractory fiber spraying machine spraying one deck refractory fiber spraying material 1, its thickness is 100-200mm.
The effect of above-mentioned refractory cement spray paint 5 is in order to prevent that heating furnace corrosive gas in running from seeing through the pad formation corrosion of refractory fiber floor to the anchoring piece on the body of heater steel plate, at refractory cement spray paint 5 external spray refractory fiber spraying material 1, because the refractory fiber spraying material forms discontinuity for the conduction of heat, thereby reaches purpose of energy saving.
Claims (2)
