Description
Technical field
The present invention relates to a kind of temperature measuring equipment, especially relate to the temperature measurement structure of a kind of use at polymeric kettle temperature-measuring port place, and the polymeric kettle that adopts this temperature measurement structure.
Background technology
Under polymeric kettle, point for measuring temperature is positioned at polymeric kettle low head top, and it installs the thermometric thermal resistance, the still interior reaction temperature is measured in time and reached interior behaviour chamber in order to immediately understand the production reaction condition.Because polymeric kettle bottom temperature has very important effect in course of reaction, the intermittence type polymerization reaction, polymeric kettle needs the heating and cooling reactions change often, the phenomenon that causes expanding with heat and contract with cold is obvious, when each production cycle finishes, lower point for measuring temperature is to judge the polypropylene important evidence whether material spray finishes in polymeric kettle, only have lower point for measuring temperature temperature close with middle part point for measuring temperature temperature, illustrate that blowing finishes, if a upper production cycle blowing is not thorough, there is more polypropylene to stay in polymeric kettle, feed intake into next time and very easily cause the production accident that material " roof fall " phenomenon is serious to occur.In addition, in course of reaction, the temperature of lower point for measuring temperature is also to judge the whether normal important technical parameter of polymerisation, when finding that in reaction polymeric kettle temperature of lower and middle part temperature spread are larger, illustrate that bottom has a large amount of reaction heat to fail immediately to withdraw, belong to the abnormal polymerization reaction, comparatively serious " sizing " reacting phenomenon may occur, or " sudden and violent poly-" reacting phenomenon occur, this temperature spot can be processed in time as people the temperature reference of abnormal response.The opening after the maintenance such as manhole processes for maintainer turnover at polymeric kettle, need to do the special process of removing impurity in still in polymeric kettle and be called false material reaction, in false material reaction process, lower point for measuring temperature is to control liquid propylene whether to reclaim important technical parameter thoroughly, if liquid propylene can not reclaim thoroughly, to material spray in flash vaporization kettle, very easily cause the propylene displacement not thorough, quick-fried security incident occurs to dodge.Yet (see accompanying drawing 4) in the temperature-measuring port structure under polymeric kettle in prior art, particularly in temperature-measuring port structure under the polymeric kettle used in liquid phase batch (-type) small scale bulk polymerization technique manufacturing enterprise, the kettle outer wall of polymeric kettle kettle 10 and kettle chuck 11 and thermal resistance outer pillar body 30 threes be welded together, the outer pillar body 14 of the thermal resistance of same temperature-measuring port 13 at present also links together with the kettle outer wall welded seal of polymeric kettle kettle 10, and outer pillar body 30 front ends of thermal resistance become the arcuation shrink welded to be connected on the polymeric kettle kettle 10 at lower temperature-measuring port 13 places, make the more concentrated unfavorable phenomenon in stress part at lower temperature-measuring port place, exist the penetrating crack phenomenon that temperature-measuring port crackle easily occurs or even the thick left and right of penetration of cracks 30mm kettle occurs, and then cause recirculated water in chuck to leak in still, cause the catalyst failure of polymerisation, thereby can cause or " sizing " reaction reactionless without the clear soup of polymerisation, when serious, even can cause a large amount of propylene to leak to the outer generation that can cause explosion accident of still, as the polymeric kettle of III class hierarchy pressure vessel because of lower temperature-measuring port fault occur to reprocess the frequency higher, or even cause reprocessing of apparatus body, make the safety coefficient of equipment greatly reduce, be difficult to reach the safety standard of III class hierarchy pressure vessel, finally may cause thus the economic loss of whole equipment scrapping to occur.
