Abstract
(b) The utility model relates to a device for connecting a denitration device reactor and a cold denitration steel structure. The denitration device reactor is characterized by high temperature and high pressure, wherein when smoke passes from inside of the reactor, a steel structure rod piece is inevitably affected by a phenomenon of expanding with heat and contracting with cold; meanwhile high static friction force is generated with the cold steel structure at the bottom to result in adverse effect on the structure. To reduce the contact surface friction coefficient is an effective method when constant load cannot be optimized. The connecting device comprises a supporting beam 2 of a denitration device reactor 1, wherein a cushion block A 3 is welded at the bottom of the supporting beam; the cushion block A is in contact with a cushion block B 4; the cushion block B is welded at the top of a cold steel structure beam 5. The connecting device disclosed by the utility model serves as a support for the denitration device reactor.
Description
technical field:
the utility model 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, in bearing catalyst module load, also bear a series of loads such as steel construction deadweight, dust load, cigarette air channel load, crane load, be passed on the cold conditions denitration steel construction of bottom by members such as post, beam, supports with above-mentioned load.Denitrification apparatus reactor feature is HTHP, and in the time that 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.
utility model content:
the purpose of this utility model is to provide a kind of device for denitrification apparatus reactor and cold conditions denitration steel structure connection, effectively reduce the coefficient of friction of denitrification apparatus reactor and bottom cold conditions steel structure girder Contact face, in 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, described cushion block A has polytetrafluoroethylene floor on the face contacting with described cushion block B; Described cushion block B has polytetrafluoroethylene floor on the face contacting with described cushion block A.
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 utility model 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, when design, cushion block width is less, be about 80～100mm, to guarantee that bottom cold conditions steel structure girder load-bearing is as 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 the utility model denitrification apparatus reactor and bottom cold conditions steel structure girder is connected processing by steel plate, take 300MW grade Benitration reactor as 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 when 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 utility model 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, in 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.
