Abstract
The utility model relates to a boiler brickwork sealing cover improved from the existing sealing technology of boiler brickwork. The horn-shaped boiler brickwork sealing cover is made of fireproofing materials. The inner shape of horn-shaped pipes match with the external shape of brickwork penetrating pipes. The utility model is arranged on a water-cooled wall, the horn-shaped pipes of the sealing cover are sheathed with and fixed on the brickwork penetrating pipes. The large mouth ends of the horn-shaped pipes are fixed to the boiler brickwork. Then, sealing fillers are perfused out of the sealing cover. The utility model is sealed to hold smoke leaked out from the brickwork penetrating pipes in the sealing cover in boiler operation. Meanwhile, heat loss due to smoke exhaust of the boiler is reduced, and the environment of the boiler room is improved.
Description
The utility model relates to a kind of boiler setting seal closure, is the improvement to existing boiler setting Sealing Technology.
To leak one of the most serious position be water-cooling wall wall pipe place to boiler setting in the industrial production.The sealing means that adopts is to fill gasket coating at easy leakage position at present.In this way after the sealing, put stove operation for the first time and can keep and do not leak cigarette, but through after the several somes blowing out cycles of operation, because water screen tube is different with the thermal coefficient of expansion of masonry (seat clay, diatomite), the sealing way expects will the crack occur and leak cigarette once again.Like this, increase the flue gas loss of boiler, caused useless air inducing power consumption, worsened the combustion process in the stove.Simultaneously, also worsened the environment of boiler room, had a strong impact on workman's execute-in-place and patrolling and examining.
The utility model purpose is to overcome above-mentioned shortcoming of the prior art and a kind of boiler setting seal closure is provided, with the problem that solves gasket coating layer cracking, leaks cigarette.
The technical solution of the utility model is: the boiler setting seal closure is horn-like, make by refractory material, shape and wall pipe profile are complementary in its oviduct, the utility model is installed in water-cooling wall wall pipe place, seal closure oviduct be enclosed within on the wall pipe and fixing, the loudspeaker big opening end is fixed on the boiler setting, then in the airtight and watertight padding of seal closure outer filling.
Use the utility model to seal, the flue dust that leaks along wall pipe in the boiler operatiopn can be kept off in seal closure.Reduce the heat loss due to exhaust gas of boiler simultaneously, improved the environment of boiler room.
Accompanying drawing is the structural representation of the utility model embodiment.
Below in conjunction with accompanying drawing, further specify the utility model by embodiment.
In an embodiment, it is horn-like that the utility model is, and by inside and outside two-layer the composition, internal layer (1) is the alumina silicate Nomex, and outer (2) material is a glass cloth.Shape and wall pipe profile are complementary in the oviduct, the utility model is installed in water-cooling wall wall pipe (3) to be located, seal closure oviduct be enclosed within on the wall pipe and with steel wire with the two tighten, the loudspeaker big opening end is pressed on the furnace wall with steel loop and is fixed the back in the airtight and watertight padding of seal closure outer filling sepiolite with angle steel.
Claims (2)
1, a kind of boiler setting seal closure is characterized in that the boiler setting seal closure is horn-like, and shape and wall pipe profile are complementary in the oviduct.
2, the boiler setting seal closure according to claim 1 is characterized in that seal closure is by inside and outside two-layer the composition.
