Description
Technical field
The present invention relates to a kind of heating stove tube high-temperature fibre sealing technology, especially a kind of sealing technology that is used for petrochemical industry tubular heater boiler tube.
Background technology
The tubular heater boiler tube of petrochemical industry all needs to seal filling usually, and tradition to the encapsulating method of heating furnace tube is: with ceramic fiber layer shop blanket or with the ceramic fibre chunk slit between boiler tube and the stove roof plate is clogged.Under the cold conditions situation, boiler tube can well be sealed, but under the condition of heating furnace operation, because the effect of thermal (temperature difference) stress, displacement on horizontal direction and the vertical direction can appear in heating furnace tube in running, this has brought a difficult problem with regard to the sealing of giving boiler tube, because the elasticity of used ceramic fiber layer shop blanket or ceramic fibre chunk can not compensate the new slit that occurs after the boiler tube displacement, just might cause following accident:
1, thermal current passes stove roof plate, influences energy-efficient performance and security performance;
2, thermal current corrodes the anchoring piece of ceramic fibre, causes the ceramic fiber layer etc. at furnace roof place to come off;
3, cause the maintenance of heating furnace and parking frequency to increase, increase operating cost.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of heating stove tube high-temperature fibre sealing technology, can effectively seal the slit that produces because of the boiler tube displacement under the hot conditions of heating furnace running.
The present invention solves the problems of the technologies described above the technical scheme of being taked: a kind of heating stove tube high-temperature fibre sealing technology, between boiler tube and stove roof plate, be filled with seal member, and comprise the steps:
The first step: design hot side material, huyashi-chuuka (cold chinese-style noodles) material model on request;
Second step: according to hot side material, the cut-parts of huyashi-chuuka (cold chinese-style noodles) material model, make bag, bag comprises hot side material layer and huyashi-chuuka (cold chinese-style noodles) material layer;
The 3rd step: filled high-temperature cellucotton in the bag;
The 4th step: sealing, pruning, make seal member;
The 5th step a: end and the heating furnace tube of the bag of seal member are fixed; The other end and the stove roof plate of bag are fixed, and this bag moves with boiler tube.
On the basis of such scheme, second step comprised carries out dimension control to bag.
Described dimension control comprises:
One, makes model, model is carried out dimension control;
Two, compound size is checked in blanking in batches;
Three, make the semi-finished product bag, every semi-finished product are tested.
The present invention adopts special seal member, make the bag form with hot side material layer and huyashi-chuuka (cold chinese-style noodles) material layer, the hot side material layer is fitted between boiler tube and the stove roof plate, and the huyashi-chuuka (cold chinese-style noodles) material layer leaves enough displacements, be that bag has certain sag, bag moves with boiler tube and moves, and the high temperature fiber in the bag is cotton because the elastic force effect of self, bag can both be filled between the slit all the time, thereby reach the effect of effective sealing.
Concrete, the bag of described seal member has " U-shaped " cross sectional shape, and the hot side material layer is arranged on the outside of huyashi-chuuka (cold chinese-style noodles) material layer, and the huyashi-chuuka (cold chinese-style noodles) material layer has enough displacements.
Described bag, the end that itself and boiler tube are fixed has the square shaped teeth limit, and each side's tooth on this square shaped teeth limit is coated on a boiler tube outside and fixing with it by clip.Concrete, the part of boiler tube is by the hot side material layer integral coating of square tooth at least.
In order to coat whole boiler tube, the width of described side's tooth is not less than the girth of boiler tube.
Described bag, the end that itself and stove roof plate are fixed has flanging, and this flanging and stove roof plate are fixed.Concrete, flanging is pasted fixing in the one side of hot side material layer with stove roof plate mutually.
Described hot side material layer is an aluminium silicon boron continuous-filament woven fabric.
Described huyashi-chuuka (cold chinese-style noodles) material layer is for applying or flooded the high silica continuous-filament woven fabric of polytetrafluoroethylene (PTFE), and it can continue anti-900 ℃ high temperature, applies polytetrafluoroethylene (PTFE) and can improve air-tightness, water proofing property and chemical resistance.
Huyashi-chuuka (cold chinese-style noodles) material layer and hot side material layer are sewn into bag with higher temperature line.
The invention has the beneficial effects as follows:
1, safer reliable with respect to the conventional seals mode, effectively continue high temperature resistantly to reach 1370 ℃;
2, long service life, maintenance cost is low;
3, simple installation, heat seal is effective, saves the energy;
4, the back is installed and becomes as a whole with stove roof plate, and seal member can move freely with the displacement of boiler tube, replaced the fiber liner under the cover plate, solved the difficult problem that liner comes off easily thus with boiler tube.
