Abstract
The utility model relates to a catalyst basket cover which comprises a cover body and cover plate units arranged along the circumferential direction of the cover body, wherein except the sides, far away from the center of the cover body, of the cover plate units, the rest sides of the cover plate units are respectively provided with a baffle; and screen plates are arranged between the cover plate units and the cover body. The sides, close to the circumference, of the cover plate units on the basket cover, are not provided with the baffles, so that a small part of gases can pass through the cover plate units, and after flowing into the cover plate units and flowing in through the screen plates, the gases pass through the catalyst arranged at the top in the catalyst basket, so that the catalyst is utilized and the utilization efficiency of the catalyst is improved, thus higher product net value can be obtained.
Description
Technical field
The utility model relates to a kind of reactor that is used for catalyst system and catalyzing, owing to relate to the basket lid of the basket in the reactor.
Background technology
Traditional fixed bed reactors because its high-pressure space is very precious, in order to reach the purpose of Peak output, should improves the loadings of catalyst as much as possible and improve its catalytic efficiency, thereby make reaction more thorough.Traditional overall diameter is provided with the envelope gas-bearing formation to reactor for beds top, and is as shown in Figure 1; Owing to have sedimentation phenomenon in catalyst reduction and the use, the purpose that beds top is provided with the envelope gas-bearing formation is to prevent the gas short circuit.
But the shortcoming of existing fixed bed reactors envelope gas-bearing formation is:. the dead angle appears in the top of beds, and certain catalyst does not have gas through not having catalytic action, has reduced the utilization ratio of catalyst.
The utility model content
The utility model is to provide a kind of basket basket lid that can improve the utilization rate of catalyst.
The utility model is realized through following technical scheme:
A kind of basket basket lid comprises lid, and along the cover plate unit that the lid circumferencial direction is arranged, said cover plate unit is provided with sieve plate except that being equipped with baffle plate away from all the other each sides the lid central side between cover plate unit and the lid.
As improvement, said cover plate unit is the fan annular.
As improvement, said lid is provided with suspension ring.
The basket basket lid of the utility model; The cover plate unit that basket covers does not have baffled near circumference, the gas of fraction is passed through, after gas gets into the inflow of cover plate process sieve plate; Catalyst through the basket inner top; Make the catalyst of basket inner top obtain utilizing, improve the utilization ratio of catalyst, thereby obtain higher product net value; On lid, establish suspension ring, open basket, make things convenient for the dismounting and the maintenance of basket through suspension ring.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A profile among Fig. 1;
Fig. 3 is the gas flow figure of overall diameter when beds uses traditional basket basket lid;
Fig. 4 is the gas flow figure of overall diameter when beds uses the basket basket lid of the utility model.
Wherein: 1 is lid, and 2 is the cover plate unit, and 3 is sieve plate, and 4 is baffle plate, and 5 is suspension ring.
The specific embodiment
Specify the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2; The basket basket lid of the utility model comprises lid 1, and lid 1 is provided with suspension ring 5; Lid 1 circumferencial direction is provided with the cover plate unit 2 of 4 fan annulars; Cover plate unit 2 removes and is equipped with baffle plate 4 away from all the other each sides of lid 1 central side, also can be that cover plate unit 2 is provided with the baffle plate of being with through hole away from lid 1 central side, is provided with sieve plate 3 between cover plate unit 2 and the lid 1.
When gas flows into; Cover plate unit 2 will make the gas of fraction pass through away from a side at lid 1 center; The gas that passes through is through flowing into the catalyst of basket inner top behind the sieve plate; Concrete gas flow makes the catalyst of basket inner top obtain utilizing referring to Fig. 4, improves the utilization ratio of catalyst, thereby obtains higher product net value.
