Description
Technical field
The utility model relates to a kind of tetrafluoro of anti-lower negative pressure lining retort, especially a kind of retort of finishing the processes such as the reaction of material, synthetic, polymerization, chlorination for chemical industry, pharmaceutical engineering, and the negative pressure of minimum ability is-0.03MPa.
Background technology
In existing technology, retort lining tetrafluoro is because of the technical barrier such as can't process the bulge of tetrafluoro plate lining, shell, tear, and causes tetrafluoro plate lining to lose efficacy under high temperature and high pressure condition.For the arts demand of empty set lining, usually adopt two flange arrangements, namely cover is with tank body, tank body and respectively be connected fastening with a pair of main flange at the bottom of the tank.Heating jacket has to be divided into up and down two parts, has reduced the heating surface (area) (HS of chuck,, simultaneously, be connected to a pair of flange in retort lower end and numerous double-screw bolt and nuts, wasted heat, wasted heat energy, limited the intensification of retort, the normal function of heating.
In existing technology, the inwall in empty set tetrafluoro plate retort matches by its internal diameter size, makes the tetrafluoro inner sleeve, and empty set is in tank, and the space that exists 1～3mm not wait between tank skin and the lining has formed the natural air interlayer.The sealing surface of retort master's flange and each mouth of pipe is not made adhesion process with the flange flange of tetrafluoro lining yet.Can't form Sealed sandwich between cover and can body and the tetrafluoro plate lining, the interlayer Air is in free state forever.When retort under high temperature, lower negative pressure operating mode, the every intensity index of PTFE sharply descends.The air of interlayer is heated suddenly and expands, lining has been produced external pressure has been subjected to again lower negative pressure effect in the tank simultaneously, tetrafluoro plate lining under the dual-pressure effect, unstability and produce shelling, tear or deformation of cylindrical.
In existing technology, also have on above-mentioned empty set tetrafluoro plate base, added adhesive, very smooth smooth on the surface, but producer offers some clarification on not ability negative pressure, and can not be high temperature resistant; Having added wire netting also can only anti-little negative pressure, 110～120 ℃ of operating temperatures, but still be two flange arrangements.
In order to solve the dual pressurized problem of lining, manufactory once adopted remedial measure to be, adopt vacuum line with the tetrafluoro lining interlayer of retort cover and retort tank body tetrafluoro plate lining interlayer at retort outside pipeline connection, vavuum pump is communicated with vacuum line, consist of vacuum system, vavuum pump and retort vacuum system start close synchronously synchronously, make the interlayer place what vacuum state of tetrafluoro plate lining and tank skin, with the negative pressure in the tank that contends with.Although on principle, as if solved the vacuum equalization problem, but ignored the impact of the linear expansion stress of PTFE deadweight under the high temperature, boundary stress that the agitator rotation produces, PTFE, under these composite factor effects, tetrafluoro plate lining or deformation of cylindrical.Therefore, empty set tetrafluoro plate retort can't solve the tetrafluoro plate that the serves as a contrast problem of anti-negative pressure at high temperature.
