Description
Technical field
The present invention relates to the installation method of a kind of Novel SCR Benitration reactor of field of Environment Protection inner catalyst module.It is a kind of improvement to former external imported technology Benitration reactor catalyst module mounting technique.Belong to environmental technology field SCR (SCR) gas denitrifying technology.
Background technology
At present SCR (SCR) denitrating flue gas method, because its efficiency is high, stable performance, is widely used in engineering both domestic and external, becomes smoke evacuation tail gas and remove the mainstream technology of nitrogen oxide.SCR denitrating system refers under the effect of catalyst, by spray into ammonia in flue gas, the reduction of nitrogen oxide in flue gas is become to the reaction unit system of nitrogen G&W.The capital equipment of SCR denitrating technique is SCR reactor.And core component in SCR reactor is catalyst module.
Denitrification catalyst module general (comprising imported product) is standard component, and module size is generally: be about 2m(and be less than but approach 2m), wide about 1m (be less than but approach 1m), the cuboid of high 0.6～1.8m scope.Module length and width size is comparatively fixing, and short transverse size is unfixing.Catalyst module weight is according to the difference of its height, and weight change is larger, every module weight generally between 0.6～1.5T, the heaviest 2T that is no more than.In general a SCR reactor need arrange 2 to 4 layers of catalyst according to technological requirement (namely reactor domestic demand correspondence arranges 2 to 4 layers of catalyst brace summer.Between catalyst layer, spacing is about 3.5m.), and every one deck catalyst is made up of near a tiling one of multiple catalyst module.
Catalyst module main active is V2O5, the rare earth compounds such as TiO2, WO3, and catalyst module is the parts of the most valuable and core of whole denitrating system.Catalyst module need need to change once every 3～5 years.Therefore adopt one safe reliable, it is particularly important that easy-operating mounting means just seems.
Catalyst module is installed the mounting technique while always continuing to use foreign technology introduction all the time.Main mounting technique has two kinds: one is when this layer of catalyst module is installed, by the overhead trolley arranging at the bottom of last layer support steel beam beam, catalyst module lifting is lifted from reactor outside to reactor the inside (transverse shifting), then by the rail " catalyst dolly " (a kind of coaster of walking on two trapped orbits) arranging in this layer of catalyst module brace summer altitude range, catalyst module is manually pushed to assigned position (vertically moving).Another kind method is just in time contrary: by " flooring " double-rail track of " temporarily " is set at this layer, use " catalyst dolly " catalyst module manually to be pushed to reactor the inside (transverse shifting) from reactor outside, then by the overhead trolley arranging at the bottom of last layer support steel beam beam, catalyst module is lifted into assigned address (vertically moving).
Above-mentioned two kinds of mounting techniques all need to arrange " catalyst dolly ".Due to the existence of " catalyst dolly ", all need the supporting setting can be at the double-rail track of this layer of walking.The first lifting mode above-mentioned, due to the reason of " catalyst trolley track ", horizontal support is not established in this layer of girder steel top flange, affect the stable of this layer of catalyst module support steel beam, therefore popular response device inner catalyst module support steel beam all needs to adopt box beam, can solve stable problem, the minimum constructive height of this layer of catalyst module brace summer also needs 600mm.This brings a lot " trouble " and restriction to reactor body structural design, causes reactor body design steel consumption large, and structure is not quite reasonable; Though not affecting every layer of horizontal support in reactor, arranges first scheme, but often install a row catalyst module and need remove the " " double-rail track temporarily of one section of this layer being arranged on " flooring ", one whole layer of catalyst module is installed, the overhead trolley that needs this layer of end face of being dismounted for multiple times to vertically move, installation is taken a lot of work, is required great effort, and efficiency is low.
In view of the Installation Modes of these two kinds of conventional catalysts in engineering, because " " problem of track is brought the trouble in a lot of designs and construction to catalyst dolly.We have invented denitrification catalyst module installation system a kind of without catalyst dolly and its supporting track, easy, reliable, easy to operate, that be convenient to building site installation thus.
