Between tube structure in.
In order that the security of denitration reaction device is higher, prevent that the reliability that side is blown is higher, roof component 2 also wraps
Venting of dust explosion structure is included, venting of dust explosion structure setting is in the top of roof, venting of dust explosion structure when the pressure inside tube structure is more than preset value
Open, high pressure draught discharges upwards.Venting of dust explosion structure can be rupture disk or safety valve or roof is arranged to metal
Film, groove 21 is carved with metallic film, metallic film is torn apart when being under pressure from the place for being carved with groove 21, groove
21 shape can be cross groove 21 or M shape groove 21.
Further, in order to prevent denitration reaction device blows rear ammonia moment escape from causing personnel to injure, the housing
Structure also includes safe well construction 6, and safe well construction 6 is to be arranged on above roof, including four side walls 22 and a top 23,
Four side walls 22 surround a hollow square cylinder, and top 23 is the platy structure of lightweight, and top 23 is covered in square cylinder
Top, and be flexibly connected with square cylinder, the lower section of four side walls 22 of safe well construction 6 and four inwalls 11 of tube structure
Upper seal connection, the top of safe well construction 6 may extend to outside factory building.When explosion time, inside occur for denitration reaction device
Gases at high pressure wash the venting of dust explosion structure of roof open, into the safe well construction 6 of top, make the ammonia of inside will not be in lower moment
Release, but flowed up along safe well construction 6, the top 23 for finally washing safe well construction 6 open outwards discharges.In order to mitigate
Injury of the ammonia to human body, spray system and sensor, sensor is set to detect sky around the top 23 of safe well construction 6
The concentration of ammonia in gas, when the concentration of ammonia in air is more than preset value, spray system starts, by nozzle to escape pit knot
Water smoke is sprayed at the top 23 of structure 6, by the ammonia in water smoke absorption air so as to reduce the concentration of ammonia in air, mitigates ammonia
Injury to human body, while also function to the effect of fire extinguishing.In order to prevent denitration reaction device blows rear wall component 1 from deforming and lead
Cause the strong point of safe well construction 6 to tilt, support bar is set in the lower section of safe well construction 6, one end of support bar is supported on peace
The lower section of side wall 22 of full well construction 6, the other end supports on the ground, or sets suspension bracket, one end of suspension bracket on the top of factory building
It is connected with the upper frame of factory building, the other end is connected with the side wall 22 of safe well construction 6, escape pit is being hung in denitration reaction device just
Top.
Further, for the reliability of reinforced sidewall component 1, side wall assemblies 1 is better protected from side and blow, such as
Shown in Fig. 6, inwall 11 is arranged to the first inwall 114 and the second inwall 115, solid between the first inwall 114 and the second inwall 115
Surely there is the second outer wall 121, the second outer wall 121 also uses high strength fibre cloth.Side wall assemblies 1 are by double-deck inwall 11 and double-layer high-strength
Spend fiber cloth to be arranged at intervals, make the shock-absorbing capacity of side wall assemblies 1 more preferable.
Further, in order to improve the sealing of denitration reaction device, gas of the denitration reaction device in normal operation is made
Close property is more preferable, is provided with sealing ring between two adjacent side wall assemblies 1, between side wall assemblies 1 and roof, sealing ring is specifically set
On the position that two adjacent inwalls 11 contact and on position that inwall 11 contacts with roof, side of the sealing ring along inwall 11
Or the side extension of roof, sealing ring can use teflin ring.
In the present embodiment, when explosion time occurs in denitration reaction device, its internal gas rapid expansion, while offside
Wall component 1 and roof produce moment very big impulsive force, and inwall 11 ruptures under gas shock, the high strength fibre cloth of outer wall 12
Outwards heave, due to the parcel and cushioning effect of high strength fibre cloth, the fragment of inwall 11 will not scatter everywhere, avoid fragment
Hurted sb.'s feelings with air-flow；The venting of dust explosion structure of roof is washed open by air-flow simultaneously, and the flue gas for carrying ammonia flows up along safe well construction 6,
Wash the top 23 of safe well construction 6 open；The ammonia concentration that sensor detects in air is more than preset value, triggering spray system to
Lower spray water.
