Abstract
The utility model relates to a groove type cross fulcrum ball which is composed of a center straight-through hole (1) and grooves (2) and is characterized in that a ball body is composed of an upper half ball and a lower half ball, 3 to 7 alternate grooves (2) are respectively distributed on the surfaces of the upper and the lower half balls evenly, and the center of the ball body is provided with the center straight-through hole (1). The groove type cross fulcrum ball has the advantages that: 1. the groove type cross fulcrum ball is larger than the superficial area, gas and liquid move in a rotary way, the flux is large, and the distribution capability is good; 2. the groove type cross fulcrum ball lowers the resistance, reduces the self weight in a tower, has strong acid and alkali resistance, stands fire, and has strong compressive resistance and high utilization ratio.
Description
Affiliated field
The utility model relates to a kind of inserts that is used for the petrochemical industry reactor, specifically is a kind of slot type intersection fulcrum ball.
At petrochemical industry, as ethylene hydrogenation cracking unit, catalytic reforming unit, isomerization unit, in the reaction equipment such as demethylation device, no matter the inertia alumina ball that uses is perforate at present, or groove, all there is the unification problem in its performance, make to exist resistance big in the reaction tower skewness, practical problem such as efficient is low.
Summary of the invention
At the problems referred to above, the purpose of this utility model is to provide a kind of slot type intersection fulcrum ball of petrochemical reactors inserts, and it is reasonable that it has planform, the gas-liquid flux is big, and gas-liquid becomes rotating, thereby has promoted reactor reaction complete, the efficient height, energy savings reduces characteristics such as cost.
Invention main points of the present utility model are: its spheroid divides episphere and lower semisphere, and groove is alternately arranged on the surface of upper and lower hemisphere, and evenly distributes, and respectively has 3～7.There is a center drilling in spheroid central authorities.Two center drillings connect into the central passage of a void column shape at the axis direction of spheroid up and down.
The utlity model has following advantage: 1, specific area is big, and it is big that gas-liquid is rotating motion flux, and distribution performance is good; 2, reduce resistance, alleviate the own wt in the tower, strong alkali-acid resistance, high temperature resistant, compression strength is big, the utilization rate height.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model, among the figure, and 1-central straight through hole, 2-groove.
The specific embodiment
Embodiment: at first, adopt unique ceramic formula, its primary raw material is: alundum (Al, feldspar, Jiepai clay, kaolin, talcum, by metered proportions, ball milling enters suction iron, advances slip drying press again, vacuum refining mud.Secondly, extrusion modling, promptly at 5 grooves of upper and lower surface compacting of ball, the alternately even of top and bottom distributes, and its groove is once to be pressed into by mould in manufacturing process.Article 5, groove (2) all is connected with the upper and lower opening of center drilling (1) respectively.After high temperature sintering form.
The utility model is in reaction tower, and gas-liquid, liquid can also can be flowed into, be flowed out by the groove free flow by centre bore, makes operation unblocked, thereby has improved flow velocity, has reduced resistance.
The utility model energy savings reduces cost, and has prolonged the working time, has reduced the overhaul number of times, thereby has improved economic benefit.
Claims (1)
1, slot type intersection fulcrum ball, it is made up of central straight through hole (1) and groove (2), it is characterized in that spheroid is divided into episphere and lower semisphere, groove (2) is alternately arranged on the surface of upper and lower hemisphere, and evenly distribute, respectively there are 3～7, there is a central straight through hole (1) in spheroid central authorities.
