Abstract
The utility model discloses a coil type reactor. Necking down pipe sections (3) and straight pipe sections (2) are alternatively arranged at each coil of a pipe (1) rising spirally; necking down openings at two ends of the necking down pipe sections (3) are connected with the straight pipe sections (2) with the same caliber; the length of the necking down pipe section (3) is equal to that of the straight pipe section (2) and is 10 to 15 times of the diameter of the straight pipe section (2); and the diameter of the necking down pipe section (3) is 9/10 of that of the straight pipe section (2). The coil type reactor can change the flowing state and enhance the turbulence degree in the pipe so as to improve the polymerization degree of mixed materials. Especially, when being used for producing high pressure polyethylene and propathene, the reactor can solve the problem of enhancing the conversion per pass of ethylene or propene which is not thoroughly solved in the prior art.
Description
Technical field
The utility model relates to a kind of reactor drum, is a kind of coil pipe type reactor specifically, and it is specially adapted to high-pressure polyethylene and Vestolen PP 7052 production is used.
Background technology
Traditional major equipment coil pipe type reactor that is used for high-pressure polyethylene and Vestolen PP 7052 production all is to adopt isometrical tubular reactor, and it is along the rising of spiraling clockwise or counterclockwise, the pipe reaction equipment of formation by an isometrical weldless steel tube.200510101516.0 a high yield production has ethene polymerization method and the tubular reactor that is used for this method of the product of various performances; Provide a kind of tubular reactor in order to improve the production efficiency of vinyl polymerization; It has been to use a kind of reaction zone that comprises first reaction zone and second reaction zone; The xsect of second reaction zone and length are greater than first reaction zone, and ethene is introduced into from two or more different points at second reaction zone with catalyzer.But still the per pass conversion of fail fundamentally to improve ethene or propylene reduces the reaction times, shortens the length of reaction tubes.
Summary of the invention
The purpose of the utility model provides and a kind ofly can strengthen turbulent flow to the material of flowing through, thereby improves the tubular reactor of mixture extent of polymerization.
The coil pipe type reactor that the utility model provides, the pipe that rises of formula in the shape of a spiral, every circle has been arranged alternately necking down pipeline section and straight length, and bore ground such as the contraction mouth at necking down pipeline section two ends and straight length are connected.
In addition, in the utility model, also has preferred example for the necking down pipeline section in above-mentioned; Specifically be; The equal in length of the length of necking down pipeline section and adjacent straight pipeline section, and equal 10～15 times of straight length diameter, necking down pipeline section diameter is equivalent to 9/10 of straight length diameter.
If the utility model is applied to high-pressure polyethylene and Vestolen PP 7052 production; Except above-mentioned structure; The coil pipe type reactor of the utility model can also comprise other parts; Like pre-reactor, pressure warning unit measuring device, TM measuring device, electrostatic detection appearance and sample divider etc., they necessarily randomly are included in the reactor drum of vinyl polymerization.
The utlity model has following advantage:
Strengthen raw material and initiator mixed effect, improve per pass conversion, shorten the reaction times, reduce tube length of reaction tube, reduce production costs.For reaction monomers ethene (or propylene) and catalyzer; Because different in kinds such as density; When flowing through the necking down pipeline section repeatedly with the interval straight length; Change flow state in the pipe, increased turbulent extent, and then solved the raising ethene that not have thoroughly solution in the prior art or the problem of propylene per pass conversion.It is applicable to oxygen or organo-peroxide to be the gas phase high pressure polymerisation reaction of catalyzer.
Description of drawings
Fig. 1 is the structure iron of the utility model.
Embodiment
With reference to Fig. 1, the coil pipe type reactor that the utility model provides, there are import and export (4,5) at pipe 1 two ends of formula rising in the shape of a spiral, and every circle has been arranged alternately necking down pipeline section 3 and straight length 2, and the contraction mouth at necking down pipeline section 3 two ends is connected with straight length 2 ground such as bore such as grade.
The equal in length of the length of necking down pipeline section 3 and straight length 2, and equal 10～15 times of straight length 2 diameters, the diameter of necking down pipeline section 3 is equivalent to 9/10 of straight length 2 diameters.
The utility model in use, for example when being used for the gas phase high pressure polymerisation of ethene or propylene, when ethene (or propylene) monomer and oxygen (or organo-peroxide) catalyzer repeatedly through necking down pipeline section 3 during with straight length 2; Because the difference of their character such as density, increased the difference of two kinds of differences or multiple flow of matter speed, strengthened the tube fluid turbulent extent; And then improved the per pass conversion of ethene or propylene; Shorten the reaction times, reduced tube length of reaction tube, reduced production cost.
Claims (2)
