Abstract
The invention relates to a device for connecting a denitration device reactor with a cold-state denitration steel structure. The denitration device reactor is characterized by high temperature and high pressure, when smoke passes through the denitration device reactor, the steel structure rod piece inevitably generates expansion with heat and contraction with cold, and simultaneously generates great static friction with a cold steel structure at the bottom, thereby generating adverse effect on the structure. When constant load cannot be optimized, reducing the friction coefficient of the contact surface is an effective method. The invention comprises the following components: denitration device reactor (

Description
technical field:
the present invention relates to a kind of device for denitrification apparatus reactor and cold conditions denitration steel structure connection.
background technology:
it act as support catalyst module denitrification apparatus reactor, when bearing catalyst module load, also bear a series of loads such as steel construction deadweight, dust load, cigarette air channel load, crane load, with above-mentioned load, by members such as post, beam, supports, be passed on the cold conditions denitration steel construction of bottom.Denitrification apparatus reactor feature is HTHP, and when inside has flue gas to pass through, its steel structural rod piece will inevitably produce the phenomenon of expanding with heat and contract with cold, and produces very large stiction, to structure generation adverse influence with bottom cold conditions steel construction simultaneously.When dead load cannot be optimized, reducing contact-making surface coefficient of friction is a kind of effective way.
summary of the invention:
the object of this invention is to provide a kind of device for denitrification apparatus reactor and cold conditions denitration steel structure connection, effectively reduced the coefficient of friction of denitrification apparatus reactor and bottom cold conditions steel structure girder Contact face, when guaranteeing structure instructions for use, denitrification apparatus reactor and bottom cold conditions steel construction steel consumption have been reduced simultaneously.
above-mentioned object realizes by following technical scheme:
a kind of device for denitrification apparatus reactor and cold conditions denitration steel structure connection, its composition comprises: the brace summer of denitrification apparatus reactor, the bottom welding of described brace summer has cushion block A, and described cushion block A contacts with cushion block B, and described cushion block B is welded on the top of cold conditions steel structure girder.
the described device for denitrification apparatus reactor and cold conditions denitration steel structure connection, has polytetrafluoroethylene floor on the face that described cushion block A contacts at the cushion block B with described; On the face that described cushion block B contacts at the cushion block A with described, there is polytetrafluoroethylene floor.
the described device for denitrification apparatus reactor and cold conditions denitration steel structure connection, is characterized in that: the width of described cushion block A and described cushion block B is 80～100mm.
beneficial effect:
support style of the present invention is according to requirements at denitrification apparatus reactor brace summer and cold conditions steel construction connecting place, the form that two cushion blocks are welded to connect with up-down structure is respectively set, during design, cushion block width is less, be about 80～100mm, take and guarantee that bottom cold conditions steel structure girder load-bearing is axial compression, two cushion block contact-making surface places adopt the chemical substances such as polytetrafluoroethylene (PTFE) to smear, to reduce the coefficient of friction of contact-making surface.
if the stiction producing between denitrification apparatus reactor of the present invention and bottom cold conditions steel structure girder is connected processing by steel plate, the 300MW grade Benitration reactor of take is example, its frictional force payload values size is about 240 tons, and when huge horizontal force calculates steel construction, steel consumption is very huge.Reactor bearing is according to its loading characteristic, utilize the physical characteristic of chemical substance, the coefficient of friction of denitrification apparatus reactor and bottom cold conditions steel structure girder contact-making surface is reduced to original 1/4, load is also corresponding is down to 60 tons of effects, and during Structure Calculation, this load is less on overall structure impact.And according to its contact-making surface loading characteristic, change two girder steel contact-making surface forms into line contact by face contact, this also meets steel construction loading characteristic.Adopt in sum seat structure will save great deal of steel.
the present invention utilizes this kind of support style effectively to reduce the coefficient of friction of denitrification apparatus reactor and bottom cold conditions steel structure girder Contact face, when guaranteeing structure instructions for use, denitrification apparatus reactor and bottom cold conditions steel construction steel consumption are reduced simultaneously, this structure has been successfully applied in some engineerings at present.
