Abstract
The utility model discloses a high -pressure tubular reactor of production polyethylene relates to the reactor, is to comprise straight tube, return bend and flange, and the both ends of its straight tube and return bend all are equipped with the flange that the specification is the same, the horizontal horizontal arrangement of straight tube more than two to being " snake " venturi tube through the more than one return bend with all straight tubes and feeding through, its one end is exporting for import, the other end, the straight tube on the equipartition the vertical axis body that passes the pipe wall, the axis body puts that one end in the straight tube is equipped with the stirring rake, the top is equipped with the drive wheel, the drive wheel transmission on the same straight tube is connected, two adjacent straight tubes respectively have a drive wheel transmission to connect, one of them straight tube on the transmission be connected with motor drive. The utility model discloses a high -pressure tubular reactor of production polyethylene, simple structure, the stirring rake that is equipped with with low costs, intraductal have improved the insufficient drawback of the interior fluid reaction of traditional tubular reactor, help improving production efficiency and product quality.
Description
Technical field
The utility model relates to reactor, particularly relates to the poly high pressure tubular reactors of a kind of production.
Background technology
Tubular reactor be a kind of in a tubular form, continuous manipulation reactor that length-to-diameter ratio is very large.Tubular reactor in actual applications kind is more.The structure of reactor can be single tube, also can be multitube parallel; Can be blank pipe, as tube cracking furnace, also can be the filling tube of filler particles shape catalyzer in pipe, to carry out heterogeneous catalytic reaction, as calandria type fixed bed reactor.In general, tubular reactor belongs to piston flow reactor, thus the situation that the residence time is general relatively short, existence reaction is insufficient of tubular reactor.
Utility model content
The utility model is intended to the deficiency for existing in background technology, and the one proposed produces poly high pressure tubular reactors.
One of the present utility model produces poly high pressure tubular reactors, by straight tube, bend pipe and flange are formed, its straight tube and the two ends of bend pipe are equipped with the identical flange of specification, plural straight tube transverse horizontal arrangement, and by more than one bend pipe, all straight tubes are communicated with in " snake " shape pipe, its one end is import, the other end is outlet, uniform the vertical axis body through tube wall on described straight tube, one end that axis body is put in straight tube is provided with stirring rake, top is provided with power wheel, power wheel on same straight tube is in transmission connection, adjacent two straight tubes respectively have a power wheel to be in transmission connection, power wheel on one of them described straight tube is connected with motor-driven.
As further improvement of the utility model, be fixedly connected with by flange screw rod between connected straight tube and bend pipe.
As further improvement of the utility model, between the flange that the described straight tube be connected is connected with bend pipe, be provided with sealing-ring.
One of the present utility model produces poly high pressure tubular reactors, structure is simple, cost is low, in the pipe of traditional tubular reactor, set up stirring rake, during work, stirring rake rotates and stirs the fluid in pipe, accelerate dissolution, improve conventional tubular reactor inner fluid and react insufficient drawback, contribute to improving production efficiency and product quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 position the utility model straight tube sectional view.
Embodiment
Below in conjunction with accompanying drawing 1 and accompanying drawing 2, poly high pressure tubular reactors is produced to one of the present utility model, be described further.
