Abstract
The utility model provides a can make gaseous kuppe that is used for circulating gas system that obtains better distribution of circulating gas, includes distribution disc (2), kuppe (4), baffle distribution disc (5), and distribution disc (2) are connected through band iron (1) support with kuppe (4), and kuppe (4) support with baffle distribution disc (5) through band iron (1) and link to each other, have reduced the volume that liquid directly spouts on the distribution disc. The gas is distributed better. The chances of entrained droplets in the gas accumulating near the distribution plate and small droplets entrained in the gas stream coalescing are reduced.
Description
Technical field
The utility model relates to the vapor phase process of using condensation technology and produces poly field, promptly a kind of pod that is used for cycle gas system that circulation gas gas is better distributed.
Background technology
In the past, in vapor phase process production polyethylene process, the distributing disc of conventional Gas-phase reactor bottom is an annular plectane, can prevent that in non-condensing technology the resin display from piling up and the assurance better gas distributes, but for the polyethylene device of introducing condensation technology, the condensing agent injection rate is bigger, be injected in the circulation gas logistics in the reactor and contain more liquid droplets, original distributing disc no longer is fit to the requirement of condensation operation.Cause the too much situation of distributing disc bottom liquid phases distribution bad, local liquid phase fraction liquid phase too high, that carry secretly when gas enters distributing disc easily, the effecting reaction zone of catalyzer is dwindled, the active reduction, even phenomenon takes place not react etc., easily cause distributing disc to stop up simultaneously, gas distribution is inhomogeneous in addition will form channel in bed, the dead band occurs, also make the local focus that produces of inside reactor, produce fritter when serious, fritter is formed bulk, finally causes stopping.
Summary of the invention
The purpose of this utility model is to provide a kind of pod that is used for cycle gas system, can effectively the liquid phase of bringing in the circulation gas be reallocated, it is minimum that the liquid phase fraction is dropped to, and reduced the possibility that a large amount of liquid streams directly is injected to distributing disc.
The utility model is achieved in that and comprises distributing disc, pod, baffle plate distributing disc, and distributing disc and pod are by the band iron support and connection, and pod supports by band iron with the baffle plate distributing disc and links to each other.
Pod is positioned at the top of distributing disc, and the lower edge of pod and distributing disc are weldingly connected by 3 band irons on same horizontal plane.
The upper limb of baffle plate distributing disc and pod is weldingly connected by 3 band irons on same horizontal plane.
Distributing disc, pod, baffle plate distributing disc are on the same center of circle.
Pod is the cone funnel shaped, and is upper coarse and lower fine.
Advantage of the present utility model is: can effectively the liquid phase of bringing in the circulation gas be reallocated, it is minimum that the liquid phase fraction is dropped to, and reduced the possibility that a large amount of liquid streams directly is injected to distributing disc.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, comprise distributing disc 2, pod 4, baffle plate distributing disc 5, distributing disc 2 passes through band iron 1 support and connection with pod 4, and pod 4 supports by band iron 1 with baffle plate distributing disc 5 and links to each other.
The upper limb of baffle plate distributing disc 5 and pod 4 is weldingly connected by 3 band irons 1 on same horizontal plane.
Distributing disc 2, pod 4, baffle plate distributing disc 5 are on the same center of circle.
By on original annular spread dish, welding a pod 4 again, gas is distributed better, pod 4 is like funnel shaped, ring is little in the original distributing disc of following chain rate, be welded on the interior ring with three band irons 1, circulation gas is through distributing disc 2 time like this, the steel plate bottom of former distributing disc is walked in part logistics, another part enters pod 4, the ring place is divided into two bursts of logistics again in pod 4, and a part enters into reactor the slit between pod 4 and distributing disc 2, and another part is injected in the grid distributor from the slit of the baffle plate distributing disc 5 of pod 4 and sidewall, carry out gas and liquid and distribute again, reduced liquid and directly sprayed into amount on the distributing disc.Gas is better distributed.Reduced that droplets entrained in the gas is accumulated near distributing disc and gas stream in the chance of entrained small droplets cohesion.
Claims (5)
1, the pod that is used for cycle gas system, comprise distributing disc (2), pod (4), baffle plate distributing disc (5), it is characterized in that: distributing disc (2) passes through band iron (1) support and connection with pod (4), and pod (4) supports by band iron (1) with baffle plate distributing disc (5) and links to each other.
2, the pod that is used for cycle gas system according to claim 1 is characterized in that: pod (4) is positioned at the top of distributing disc (2), and the lower edge of pod (4) and distributing disc (2) are weldingly connected by band iron (1) on same horizontal plane.
3, the pod that is used for cycle gas system according to claim 1 is characterized in that: the upper limb of baffle plate distributing disc (5) and pod (4) is weldingly connected by band iron (1) on same horizontal plane.
4, the pod that is used for cycle gas system according to claim 1 is characterized in that: distributing disc (2), pod (4), baffle plate distributing disc (5) are on the same center of circle.
5, the pod that is used for cycle gas system according to claim 1 is characterized in that: pod (4) is the cone funnel-form, and is upper coarse and lower fine.
