Description
Technical field
The utility model relates to steam boiler field, in particular to a kind of fuel vapor vacuum hot water furnace vacuum anti-explosion doors.
Background technique
Water heater explosion proof door is a kind of safety device to protect boiler setting, when with coal dust, oil or fuel gas be combustion
The room-fired boiler of material when misoperation, may cause burner hearth or detonation or secondary combustion occur for back-end ductwork in igniting or operation
It burns, causes furnace pressure to increase, anti-explosive door for boiler can voluntarily open pressure release to protect Boiler Furnace when pressure rise to certain value
Wall.
Explosion proof door used in water heater has explosion membrane type and two kinds of swing type, and explosion membrane type explosion proof door is by rupture disk and clamping
Device composition.Rupture disk is generally made of sheet metals such as asbestos, aluminium and stainless steels.When explosion time occurs in burner hearth or flue,
When the gas shock wave pressure of generation destroys rupture disk, play the role of pressure release, explosion membrane type explosion proof door once after, just
Will not self-resetting, and be switched on clamping device and reappose rupture disk.Rotary opening type anti-explosion door is installed on the furnace of combustion chamber more
On wall.It is divided into tilting and two kinds rectilinear by its installation site, is made of components such as doorframe, door closure and hinges.Work as burner hearth
Or when gas burst occurring in flue, door closure opens pressure release around axis automatically, then and voluntarily closes.The sealed pressure of explosion proof door
The downward pressure generated by door closure tilt angle (being usually no more than 30 °) or the weight acquisition by weight.
Currently, the mode that two kinds of explosion proof doors are the directly pressure release after detonation or second-time burning occurs carry out it is explosion-proof, it is explosion-proof
Door draw off pressure it is larger when will generate biggish sonic impinging to ambient enviroment, damage on-site producing devices, also to production operation
Personnel cause life threat, generate serious production accident.Therefore, the raising generation of boiler furnace pressure can mostly be buffered by designing one kind
The vacuum anti-explosion door of shock wave have very much realistic meaning for a person skilled in the art.
Utility model content
Based on problem above, the utility model provides a kind of fuel vapor vacuum hot water furnace vacuum anti-explosion door.This is practical new
Type using level 2 buffering and between level 2 buffering be arranged vacuum chamber by the way of to boiler furnace pressure increase generate shock wave into
Row buffering is effectively reduced the shock wave that explosion proof door pressure release comes out, avoids shock wave from damaging on-site producing devices, to production operation people
Member causes life threat, generates serious production accident.
In order to solve the above technical problems, the technical solution adopted in the utility model is as follows:
