When denitrification catalyst module is installed, first location-plate is placed on the bottom surface of sheet metal inside casing, denitrating catalyst mould
Block is deposited on location-plate successively, because location-plate has the positioning strip being bent to form, can be to the denitration catalyst of hexa-prism
Agent module carry out it is spacing so that stack it is in hgher efficiency；Sealing strip is arranged on the end of location-plate and sheet metal inside casing, and to fixed
Space between position plate and sheet metal inside casing is blocked, it is to avoid flue gas is just discharged from space without denitration process, it is ensured that de-
Nitre effect.
In above-mentioned sheet metal inside casing limit sealing structure, the location-plate both sides are respectively provided with the positioning side of strip,
The outer end face on the positioning side and bottom surface are resisted against on the internal face of sheet metal inside casing.The outer end face on two positioning sides is supported
Lean against the internal face of sheet metal inside casing so that the position of location-plate can arrive restriction, it is to avoid displacement；The bottom surface for positioning side is resisted against sheet metal
On the internal face of inside casing, smoke spillage can be avoided.
In above-mentioned sheet metal inside casing limit sealing structure, the sealing strip also includes the first gear above projection
Edge and the second gear edge positioned at underbump, the medial surface on the first gear edge are resisted against on the end face of location-plate, and described second
The medial surface for keeping off edge is resisted against on the end face of sheet metal inside casing.First gear edge and second gear edge can further avoid smoke spillage,
Ensure sealing.
In above-mentioned sheet metal inside casing limit sealing structure, the width on the first gear edge is less than or equal to location-plate
Thickness.Avoiding first gear influences the installation of denitrification catalyst module along location-plate protruding upward.
In above-mentioned sheet metal inside casing limit sealing structure, the width on the second gear edge is less than or equal to sheet metal inside casing
Thickness.Avoid second gear influences the superposed of multiple sheet metal inside casings along downwardly projecting sheet metal inside casing.
In above-mentioned sheet metal inside casing limit sealing structure, the location-plate is hot rolled steel plate.Hot rolled steel plate is in hot rolling
There are high intensity and plateau modulus afterwards, be unlikely to deform after long-term use, long service life.
In above-mentioned sheet metal inside casing limit sealing structure, the sealing strip is made up of nitrile rubber.Nitrile rubber has
There are good oil resistant, resistance to ozone, wear-resisting and chemicals-resistant corrosivity.
Compared with prior art, the present invention can be pacified by setting location-plate to the denitrification catalyst module of hexa-prism
Spacing, raising stacking efficiency is carried out during dress；By setting sealing strip, the space between location-plate and sheet metal inside casing can be carried out
Closure, it is to avoid flue gas is just discharged from space without denitration process, it is ensured that denitration effect.
