Abstract
The invention discloses an automatic filling method of a catalyst. A filling device for the automatic filling method comprises a loader and a control system. The method comprises the following steps: acquiring related filling parameters by an experiment method; inputting the filling parameters into the control system; calculating a required filling speed by the control system, and driving the motor of the filler to work; and automatically correcting the rotating speed of the motor properly according to the filling situation to acquire the best filling effect. The automatic filling method of the catalyst is applicable to dense phase filling of different reaction containers and different types of catalysts along with high operability and accurate control, can fulfill requirements of different filling environments, and can realize continuity, automation and intelligence of the filling process.
Description
Technical field:
The present invention relates to the close automatic packing method that loads process mutually of a kind of petroleum chemical industry consersion unit catalyst.
Background technology:
The filling work of the filling of granule materials, especially catalyst granules more and more comes into one's own in its relevant field.The catalyst filling technology that generally adopts both at home and abroad at present is a kind of close technology of filling mutually, can bring into play the performance of catalyst in reactor to greatest extent.The close phase filling equipment of existing granule materials generally all comprises barrel, distributing device and its drive unit; During work close phase filling device is installed in charge cask (reactor or feed bin) top; Distributing device pivots under drive device drives; Material gets into distributing device through barrel, by distributing device material is evenly spread out.Its purpose all is granule materials to be shed into some donuts pile up layer by layer in cylinder type feed bin or reactor, reaches the purpose of even filling as far as possible.
When existing close phase filling device is worked, all be, confirm an initial filling rotating speed according to experience with reference to the filling on-site actual situations; Prefill is after a period of time; The filling effect is checked in shutdown, adjusts rotating speed then and works on, and shuts down after a period of time again and checks effect; The adjustment rotating speed works on, and carries out so repeatedly.So both influenced filling efficient, also influence filling flatness and loading density.Therefore, need to realize the automation of filling process, but because the filling site environment is abominable, filling process more complicated realizes that intelligent, automatic continuous property is filled with certain degree of difficulty.
Summary of the invention:
The technical problem that the present invention will solve is: propose that a kind of catalyst is close to load automatic packing method mutually, can improve filling efficient and filling effect greatly so that the serialization of filling process, intellectuality, automation reduce the manual intervention in the filling process.
The technical scheme that the present invention adopts is: the automatic packing method of a kind of catalyst, its filling device comprise filler and control system two parts.Filler is made up of barrel, drive motors, transmission mechanism, distributing device, and said motor is installed in the barrel top, and distributing device is installed in the barrel lower end, and the two connects through transmission mechanism, and transmission mechanism is installed in barrel inside; But the control system comprises the controller that the touch-screen and of an input control order receives control instruction and is electrically connected with said motor at least.It is characterized in that said automatic packing method in turn includes the following steps:
-get that to intend the loading catalyst sample some, utilize filler to load experiment, confirm the relation of Flow-rate adjustment valve opening size and blanking velocity, and the relation of distributing device rotating speed and loading density;
-intend loading density based on this catalyst, confirm distributing device diameter and corresponding charging rate;
-load parameter through touch-screen to the input of control system, comprise the distributing device diameter, loading density, charging rate, loading height, consersion unit physical dimension etc.;
-control system controller required the initial speed of cloth calculated glassware also sends instruction, the drive motors running;
-control system controller calculates the filling bed height automatically to be changed, and drive motors changes rotating speed constantly;
After-filling a period of time, shut down and detect, find out actual filling situation and desired value and get deviation, confirm correction factor;
-through touch-screen input correction factor, confirm rotating speed again;
-filling device continues operation, loads automatically;
-calculating loading height, device is out of service when reaching preset value, accomplishes whole filling.
The present invention has following beneficial effect: the automatic packing method of this catalyst can be applicable to the close filling mutually of differential responses container, variety classes catalyst; Operability is high; Control accurately; Can satisfy the needs of different filling environment, can realize the process of loading serialization, automation, intellectuality,
The specific embodiment
Along with close phase packing method loads applying of industry at catalyst, the filling of increasing consersion unit catalyst requires to adopt this close phase packing method.Because various courses of reaction are complicated, catalyst type is various, and filling requires also various, makes filling device be difficult to the same form hundred usefulness.Therefore, the present invention has designed following loading method, and the filling device distributing device is made into each different series of diameter, and simply replace according to different demands during application, and formulated the automatic packing method of a cover with this, to satisfy different filling needs:
Early-stage preparations: at first ask for plan loading catalyst sample from the customers' place some; Carry out Physical Property Analysis; And utilize loader to load experiment, confirm relevant filling parameter, like the relation of Flow-rate adjustment valve opening size with blanking velocity; The relation of distributing device rotating speed and loading density, the relation between loading height and the filling radius etc.Suitable distributing device is confirmed in the requirements such as loading density that propose based on the client then, confirms the charging rate that adapts to simultaneously.These are operated in the laboratory and accomplish, and carry out the scene filling afterwards again.
On-the-spot filling: filler is installed in the reaction vessel top, connects the control system,, comprise the distributing device diameter, loading density, charging rate, loading height, consersion unit physical dimension etc. through touch-screen input filling parameter; Equipment moves automatically, confirms initial speed, and drives distributing device and begin rotation, in mass transport to the filler barrel, relies on gravity to move downward to distributing device simultaneously, through the distributing device of rotation material is shed away.Along with the continuous increase of charge level height, the control system calculates required distributing device rotating speed and drive motors automatically and changes rotating speed automatically.After filling a period of time, suspend filling, carry out once ready-made detection; Find out the deviation of actual filling effect and desired value, confirm correction factor and input system, the control system confirms motor speed and relative speed variation again according to new program; Along with the rising of charge level, motor speed progressively improves like this, when charge level reaches predetermined loading height; Equipment shuts down, and accomplishes whole filling process.
Data preparation: filling detects whole filling effect after finishing, and the record padding data is accumulated experience, and relative program is suitably revised, and constantly improves this loading system.
