Description
Technical field
The utility model belongs to petrochemical industry, electric power heating furnace technical field, relates generally to a kind of low heat emission energy-saving explosion-proof door.
Background technology
At present, in petrochemical industry, power domain, explosion proof door is installed all on employed heating furnace, the Industrial Boiler, in order to guarantee the safety of body of heater.Conventional explosion proof door has exposed in normal the use with problem once: at first, the heat-proof quality of conventional explosion proof door is poor, and heat is distributed by the body of body of heater, causes stove body temperature to raise simultaneously; Make heat by in the lost road of the body of heater surrounding air; Secondly, the sealing of conventional explosion proof door is relatively poor, makes furnace gas take away heat easily, causes the loss of heat, makes energy the slatterning in vain in the body of heater, has reduced the efficient of heating furnace.
Summary of the invention
For solving the problem that prior art exists, the utility model proposes a kind of low heat emission energy-saving explosion-proof door, make it have good airproof performance, safe and reliable characteristics, improve the utilization ratio of heating furnace, energy is effectively utilized.
The utility model is finished the technical scheme that its invention task taked:
A kind of low heat emission energy-saving explosion-proof door mainly is made of explosion proof door housing, adiabatic interior plug, metal rupture pressure disc, netted protective cover; Plug is positioned at the installing hole of body of heater explosion proof door in the described thermal insulation, and space between plug and the installing hole is filled by the refractory seals felt in adiabatic, and the outside of explosion proof door installing hole is welded with the explosion proof door housing, and described explosion proof door housing is made of flange and pipe nipple; The flange that is positioned at explosion proof door housing both ends connects by bolts and nuts, and be provided with the metal rupture pressure disc between two flanges, be provided with pad between metal rupture pressure disc and two flanges, and the outer setting of explosion proof door housing has netted protective cover, described netted protective cover is the cuboid structure that steel plate processes, its surface has a plurality of circular holes, and is fixed on by screw bolt and nut on the furnace wall connecting plate of body of heater.
A kind of low heat emission energy-saving explosion-proof door that the utility model proposed has good airproof performance, safe and reliable characteristics, has solved the problem of conventional type explosion proof door thermal insulation difference, has improved the utilization ratio of heating furnace, and energy is effectively utilized.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the B-B profile of Fig. 1.
Among the figure: plug in 1, adiabatic, 2, the refractory seals felt, 3, the explosion proof door housing, 4, netted protective cover, 5, the metal rupture pressure disc, 6, bolt, 7, nut, 8, pad, 9, connecting plate.
The specific embodiment
In conjunction with the accompanying drawings and embodiments the utility model is illustrated:
As shown in Figure 1 and Figure 2, a kind of low heat emission energy-saving explosion-proof door mainly is made of explosion proof door housing 3, adiabatic interior plug 1, metal rupture pressure disc 5, netted protective cover 4; Plug 1 is positioned at the installing hole of body of heater explosion proof door in the described thermal insulation, plug 1 is made of high temperature ceramic material in adiabatic, space in adiabatic between plug 1 and the installing hole is filled by refractory seals felt 2, and refractory seals felt 2 is made by ceramic fiber blanket, has effectively reduced the body of heater thermal loss; The outside of explosion proof door installing hole is welded with explosion proof door housing 3, described explosion proof door housing 3 is made of flange and pipe nipple, have a plurality of screws on the flange, the flange that is positioned at explosion proof door housing both ends is connected with nut 7 by bolt 6, and is provided with metal rupture pressure disc 5 between two flanges; Contact-making surface between metal rupture pressure disc 5 and the flange is provided with pad 8, and pad 8 is a flexible graphite gasket; Metal rupture pressure disc 5 is made by stainless steel or aluminium or copper product, and to the fluctuation sensitivity very of pressure; The outer setting of explosion proof door housing 3 has netted protective cover 4, and the cuboid structure that described netted protective cover 4 processes for steel plate has a plurality of circular holes on its surface, and netted protective cover 4 is fixed on the furnace wall connecting plate 9 of body of heater by bolt 6 and nut 7.
System pressure just often in heating furnace, Industrial Boiler, because explosion proof door adopts full-closed structure, reduced in the body of heater by the air dispersed heat, when the pressure in the stove exceeds the limiting value that stove allows, metal rupture pressure disc 5 breaks immediately, and the body of heater fluid media (medium) is able to pressure release rapidly, guarantees the safety of body of heater, the adiabatic interior plug 1 that is rushed out during pressure release, the fragment of metal explosion proof door 5 are kept off portion within it by netted protective cover 4, make it to gush out and cause human body to come to harm.
