Description
Technical field
The utility model discloses a kind of catalyst filler, it mainly is applicable to oil, and chemical industry is etc. the filling of industry experimental facilities reactor catalyst.
Background technology
For many years, along with the development of petrochemical industry, the continuous foundation of the various middle-size and small-size experimental provisions that match with it, increasing of experiment all needs the work of reactor charge catalyst.At present, loading catalyst generally adopts common funnel filling method in the reactor.CN200520142071.1 discloses a kind of catalyst filler of medium-sized fixed bed reactors; Comprise that stationary pipes, funnel and nut constitute; Stationary pipes is fixed on the center position of funnel upper shed with bracing frame; Funnel under shed position links to each other with nut with support column, and bracing frame, support column and nut link together.This utility model is compared with common funnel, only reactor die Thermal couple casing pipe is fixed on the center of medium-sized fixed bed reactors, and the filling of catalyst is not changed.
The packing method of above-mentioned catalyst exists following not enough in filling and experimentation:
(1) common funnel filling method is that reactor loads outward, and Chang Rongyi causes catalyst to spill outside the reactor in this process, makes the amount that is encased in catalyst reactor be less than the design charge weight, has Systematic Errors when estimating running thereby cause.
(2) through the funnel catalyst of packing into, not at a horizontal plane, catalyst bed layer height measure error is bigger in reactor for beds, and particularly mistake is also big more more for reactor inside diameter, and it is undesirable to cause thermocouple measurement point reaction temperature to show.
Summary of the invention
Deficiency to existing packing method; The utility model provides a kind of novel catalyst filler that a kind of suitable hydrogenation reactor catalyst filling is provided; By the outer filling of reactor is to load in the reactor, has improved the filling quality for this reason, has avoided the inaccurate of temperature demonstration; When loading a plurality of reactor especially at the same time, have more advantage.
The utility model catalyst filler comprises bracing frame, has the fixed sleeving of scale, filling notch, the domatic end and central tube; The fixed sleeving that has scale was connected with cutting ferrule with the domatic end; Bracing frame is fixedly connected with filling notch; One week of filling notch has seal groove, and central tube is connected with bracing frame crossbeam center fixation.
In the utility model, the fixed sleeving and the domatic end that have scale are one, and central tube, bracing frame and filling notch are one.Bracing frame diameter and reactor inside diameter basically identical.The bracing frame height can generally be not less than the reactor shell height along with the Design of length of reactor.
In the utility model; The concrete structure of bracing frame is: bracing frame is stand by 2 ~ 6 with the about isometric cylinder of reactor shell height; The top is fixed through a crossbeam that has central tube; The bottom flat board identical with the stand material fixed, and dull and stereotyped centre bore equates with the aperture of filling notch bottom and is fixedly connected.
In the utility model, the concrete structure that has the fixed sleeving of scale is: its length is greater than the reactor shell height, and internal diameter is slightly larger than Thermal couple casing pipe external diameter in the reactor, can be inserted in wherein, and the body surface has scale.
In the utility model; The concrete structure of filling notch is: loading port is an opening port on it; Top external diameter and reactor inside diameter basically identical, and be fixedly connected with the bracing frame column, the lower ending opening external diameter is less than reactor inside diameter; Concrete size can confirm that lower ending opening external diameter and reactor inside diameter difference must be greater than the sizes of the catalyst granules of packing into according to the size of the catalyst granules of packing into.
In the utility model; The concrete structure at the domatic end is: its outward appearance is the cone of a sealing; The top is connected with cutting ferrule with the fixed sleeving that has scale, and the size at base angle is during with downward startup fixed sleeving, and catalyst is done foundation in the inflow reactor smoothly; The sealing plane and the bracing frame base platform of bottom are in same horizontal plane, help improving the accuracy that the catalyst bed layer height is measured like this.
Compare with existing catalyst filler, the utlity model has following advantage:
(1) filling process catalyst free of losses.The utility model catalyst filler is the outer filling of original reactor to be changed in the reactor load; Be specially: elder generation packs the catalyst after the weighing in the filling notch; Filler bottom alignment Thermal couple casing pipe is slowly put into then; When reaching design catalyst loading position, start fixedly Thermal couple casing pipe downwards, the domatic end breaks away from filling notch to be made in the even inflow reactor of catalyst.
(2) the beds horizontal plane is stable.After finishing in the even inflow reactor of catalyst, at this moment this bed is placed on the catalyst filler on the uneven bed not at same horizontal plane; Outside reactor, beat the reactor outer wall gently with copper rod; Beds is given a shock, because of catalyst filler bottom is the plane, so; After copper rod beat end gently, beds was horizontal plane at this moment.This program is all continued to use in the filling of each section catalyst.
(3) beds is measured accurately.Because of fixed sleeving has scale, after finishing, every section catalyst filling all can measure bed height thereupon, and program is easy.
Description of drawings
Fig. 1 is the structural representation of the utility model catalyst filler;
Wherein: the 1-central tube, the 2-bracing frame, the domatic end of 3-,, 4-has the fixed sleeving of scale, 5-filling notch, 6-bracing frame crossbeam.
The specific embodiment
Further specify structure, method for using and the effect of the utility model catalyst filler below in conjunction with accompanying drawing.
The purpose of the utility model is achieved in that the utility model catalyst filler comprises: central tube 1, bracing frame 2, has the fixed sleeving 4 of scale, filling notch 5, supporting traverse 6 at the domatic end 3.The fixed sleeving 4 that has scale is connected with usefulness cutting ferrule of the domatic ends 3; Bracing frame 2 is fixedly connected with filling notch 5; 5 one weeks of filling notch have seal groove, and central tube 1 connects through bracing frame crossbeam 6 center fixation.
Have the fixed sleeving 4 of scale, the domatic end 3 and be one through central tube 1 and bracing frame 2, filling notch 5.Diameter and reactor inside diameter basically identical.Length can be confirmed according to the height design of reactor.
Generally speaking, be provided with the thermocouple well that is used to adorn the measurement temperature in the reactor, so; When the needs loading catalyst; Earlier load weighted mixed catalyst is poured in the filling notch 5, the thermocouples tube in the filler bottom alignment reactor is slowly put into then, in the time will reaching the filling layer; Start downwards the fixed sleeving 4 that has scale, the domatic ends 3 break away from filling notch 5 makes catalyst around the domatic end 3 evenly in the inflow reactor.After finishing in the even inflow reactor of catalyst, this moment the beds end face, as a rule not on a horizontal plane; At this moment the catalyst filler is placed on above the uneven bed; Beat the reactor outer wall gently with copper rod, because of catalyst filler bottom is the plane, so; Beat gently through copper rod, let beds become horizontal plane gradually.Observe and remember to have the scale numerical value of the fixed sleeving 4 of scale simultaneously, this moment, the catalyst filling of this section just came to an end.The filling of each section catalyst is all continued to use this program and is all over until filling.
The used material of the utility model catalyst filler can be metal materials such as polytetrafluoroethylene (PTFE), engineering plastics, aluminium or stainless steel.
