Abstract
The utility model relates to a kind of station boiler furnace roof sealing device.At present, China's station boiler furnace roof also existing in various degree is leaked out ash and leak cigarette problem, wall pipe position is particularly serious, dust starves the load that accumulation not only increases steelframe, and it is seriously overheated to make suspension rod be embedded in ash, exceed rated temperature, gone down for a long time, serious threat has been constituted to the safe operation of boiler.A kind of station boiler furnace roof sealing device, its composition comprises: aluminium silicate wool layer (3), described aluminium silicate wool layer have three layers of alumina silicate carpet veneer (2), there are under described aluminium silicate wool layer two layers of alumina silicate carpet veneer (4), three layers of described alumina silicate carpet veneer has asbestos cement float coat (1), under two layers of described alumina silicate carpet veneer, there is high-temp glue mud layer (5), there is under described high-temp glue mud layer flame retardant coating (7), there is under described flame retardant coating steam pipe (6).The utility model is applied to station boiler furnace roof sealing device.
Description
technical field:
the utility model relates to a kind of station boiler furnace roof sealing device.
background technology:
at present, China's station boiler furnace roof also existing in various degree is leaked out ash and leak cigarette problem, wall pipe position is particularly serious, dust starves the load that accumulation not only increases steelframe, and it is seriously overheated to make suspension rod be embedded in ash, exceed rated temperature, go down for a long time, serious threat is constituted to the safe operation of boiler, the subject matter that the station boiler furnace roof sealing of current China exists, refractory concrete and insulating brick is adopted to play sealing function, after longtime running, the refractory concrete soil layer of many furnace roofs produces crack, then become loose broken as adopted refractory brick, boiler is expanding with heat and contract with cold in repeatedly shutdown process, many positions are squeezed broken, therefore better oven roof sealing device is needed to occur.
summary of the invention:
the purpose of this utility model is to provide a kind of station boiler furnace roof sealing device.
above-mentioned object is realized by following technical scheme:
a kind of station boiler furnace roof sealing device, its composition comprises: aluminium silicate wool layer, described aluminium silicate wool layer have three layers of alumina silicate carpet veneer, there are under described aluminium silicate wool layer two layers of alumina silicate carpet veneer, three layers of described alumina silicate carpet veneer has asbestos cement float coat, under two layers of described alumina silicate carpet veneer, there is high-temp glue mud layer, under described high-temp glue mud layer, there is flame retardant coating, there is under described flame retardant coating steam pipe.
described station boiler furnace roof sealing device, the thickness of described asbestos cement float coat is 20mm, and described alumina silicate carpet veneer thickness is 20mm, and described high-temp glue mud layer thickness is 5mm.
the beneficial effects of the utility model:
1. the utility model boiler roof sealing is effective, and boiler leaking out, leaking ash, does not improve the efficiency of boiler, reduces environmental pollution, and also improves the security reliability of boiler.
aluminium silicate wool layer described in the utility model have three layers of alumina silicate carpet veneer, there are under described aluminium silicate wool layer two layers of alumina silicate carpet veneer, three layers of described alumina silicate carpet veneer has asbestos cement float coat, under two layers of described alumina silicate carpet veneer, there is high-temp glue mud layer, high-temp glue mud layer has high temperature resistant, shrinkage factor is little, cohesive force is strong, resistance to slag is good, alumina silicate carpet veneer Heat stability is good, high resilience, at high temperature linear shrinkage ratio is little, under described high-temp glue mud layer, there is flame retardant coating, there is under described flame retardant coating steam pipe, specific heat load and radiation loss less.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
detailed description of the invention:
embodiment 1:
a kind of station boiler furnace roof sealing device, its composition comprises: aluminium silicate wool layer 3, described aluminium silicate wool layer have three layers of alumina silicate carpet veneer 2, there are under described aluminium silicate wool layer two layers of alumina silicate carpet veneer 4, three layers of described alumina silicate carpet veneer has asbestos cement float coat 1, under two layers of described alumina silicate carpet veneer, there is high-temp glue mud layer 5, under described high-temp glue mud layer, there is flame retardant coating 7, there is under described flame retardant coating steam pipe 6.
embodiment 2:
station boiler furnace roof sealing device according to embodiment 1, the thickness of described asbestos cement float coat is 20mm, and described alumina silicate carpet veneer thickness is 20mm, and described high-temp glue mud layer thickness is 5mm.
Claims (2)
