Description
Technical field
The utility model belongs to petrochemical complex continuous aromatization device field, relates generally to a kind of catalyst hooper bottom construction.
Background technology
Petroleum chemical industry utilizes the device of catalyst a lot, and the mobile dependence self gravitation of some equipment catalyst flows from the top down.The catalyst hooper bottom construction is mainly that end socket is made to pyramidal structure at present, and cone base is opened a catalyst outlet, allows catalyst flow out voluntarily.Also have end socket is made to ellipse and circular configuration, a catalyst outlet is opened in bottom, allows catalyst flow out voluntarily.These two kinds of structures all are applicable to only have the structure of a catalyst outlet.
In the continuous aromatization device, occurred that the equipment of 12 catalyst outlets on bottom (head) of catalyst hooper is shown in Fig. 2.Now between the catalyst of end socket bottom and catalyst outlet, just there will be catalyst buildup, not flow region.
As can be seen here, above-mentioned existing catalyst hooper, in structure and use, obviously still has inconvenience and defect, and urgently is further improved.Therefore how to found a kind of a kind of catalyst hooper bottom construction of new structure, also becoming the current industry utmost point needs improved target.
Because the defect that above-mentioned existing catalyst hooper exists, the inventor is based on being engaged in this type of product design manufacture abundant practical experience and expertise for many years, and the utilization of cooperation scientific principle, positive research and innovation in addition, to founding a kind of a kind of catalyst hooper bottom construction of new structure, can improve general existing catalyst hooper, make it have more practicality.Through constantly research, design, and, after repeatedly studying sample and improving, finally create the utility model had practical value.
Summary of the invention
The purpose of this utility model is, overcome the defect that existing catalyst hooper exists, and provide a kind of a kind of catalyst hooper bottom construction of new structure, technical matters to be solved is to make between its catalyst outlet to increase by two baffle arrangements, angle between angle between cone and horizontal surface and baffle plate and horizontal surface is greater than the angle of repose of catalyst while installing, thereby guarantee that catalyst flows out fully, be very suitable for practicality.
The purpose of this utility model and to solve its technical matters be to adopt following technical scheme to realize.According to a kind of catalyst hooper bottom construction the utility model proposes, comprising: hopper end socket, cone, baffle plate, catalyst outlet.Described hopper end socket inside is provided with described cone; Described cone periphery is connected with described baffle plate; Below, the inside periphery of described hopper end socket is provided with described catalyst outlet and is connected with baffle plate.
The purpose of this utility model and solve its technical matters and can also be further achieved by the following technical measures.
Aforesaid a kind of catalyst hooper bottom construction, is characterized in that the selected angle of repose of cone and baffle plate is 35 °-50 °.
Aforesaid a kind of catalyst hooper bottom construction, is characterized in that the selected angle of repose of baffle plate and catalyst outlet is 35 °-50 °.
The utility model compared with prior art has obvious advantage and beneficial effect.From above technology contents, for achieving the above object, the utility model provides a kind of catalyst hooper bottom construction, and it comprises: hopper end socket, cone, baffle plate, catalyst outlet.Described hopper end socket inside is provided with described cone; Described cone periphery is connected with described baffle plate; Below, the inside periphery of described hopper end socket is provided with described catalyst outlet and is connected with baffle plate.
Between end socket bottom and catalyst outlet, dead band (piling up not flow regimes) is appearring when preventing that catalyst from flowing, while guaranteeing catalyst utilization and shut-down discharging, catalyst draws off to reduce fully and piles up loss, this equipment is designed to increase a cone in the middle of bottom, increase by two baffle arrangements between catalyst outlet, guarantee that catalyst is fully mobile.
Cone and horizontal plane angle and baffle plate and horizontal plane angle can be determined according to the angle of repose of catalyst.
Angle of repose is exactly slope angle of repose in fact.Bulk cargo can keep the maximum angle (the monolateral angle to ground) of natural stability state when stacking, and is called " angle of repose ".After this angle forms, more up heap adds this bulk cargo, will naturally slide down, and keeps this angle, only can increase, and strengthens floor space simultaneously.In the stacking of mound, dump, grain, often can see this phenomenon, different types of bulk cargo angle of repose is different.
The particle angle of repose claims again dust loll or stocking angle.The cone generatrices that powder dust particle is piled into while falling continuously on horizontal plate by aperture and the angle of horizontal surface.The aviation value of many dust angle of reposies is about 35 °-40 °, relevant with factors such as dust kind, particle diameter, shape and water ratio.The same dust, particle diameter is less, and angle of repose is larger; The surface smooth or particle of subglobular more of healing, angle of repose is less; The dust water ratio is larger, and angle of repose is larger.The dust angle of repose is one of dynamic characteristic of dust, is the Main Basis of design dusting equipment (as the cone of storage hopper) and pipe (leaning angle).
Therefore, as long as the angle of cone and horizontal plane angle and baffle plate and horizontal plane angle is greater than the angle of repose of catalyst, catalyst just can not piled up in the end socket bottom.This structure is applicable to the various fillers that rely on self gravitation to be circulated.
By technique scheme, a kind of catalyst hooper bottom construction of the utility model at least has following advantages and beneficial effect: catalyst utilization 100% when the utility model can improve the device operation, without piling up, catalyst-free is flow regimes not.During device shut-down discharging, catalyst can be fast draws off fully from the catalyst of top hopper goes out, and noresidue, do not waste.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification sheets, and for above and other purpose of the present utility model, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and the cooperation accompanying drawing, be described in detail as follows.
