Description

Catalyst automatic Loading method
Technical field:
The present invention relates to a kind of automatic Loading method of petroleum chemical industry consersion unit catalyst dense phase loading process.
Background technology:
The filling work of the filling of granule materials, especially catalyst granules, the field relevant at it more and more comes into one's own.The Catalyst packing technology generally adopted both at home and abroad is at present a kind of dense phase loading technology, can play the performance of catalyst in reactor to greatest extent.Existing granule materials dense phase loading equipment generally all comprises barrel, distributing device and its drive unit, dense phase loading device is arranged on charge cask (reactor or feed bin) top during work, distributing device pivots under drive unit drives, material enters distributing device through barrel, is evenly spread out by material by distributing device.Its object is all granule materials is shed in cylinder type feed bin or reactor some donuts to pile up layer by layer, reaches the object of filling even as far as possible.
During existing dense phase loading device work; all with reference to filling on-site actual situations; empirically determine that one is initially loaded rotating speed; after prefill a period of time; filling effect is checked in shutdown, then adjusts rotating speed and works on, shut down view result again after a period of time; adjustment rotating speed works on, and so repeatedly carries out.So both affect filling efficiency, also impact filling flatness and loading density.Therefore, need the automation realizing filling process, but severe owing to loading site environment, and filling process more complicated, realizes continuity that is intelligent, automation and is filled with certain difficulty.
Summary of the invention:
The technical problem to be solved in the present invention is: propose a kind of catalyst dense phase loading automatic Loading method, can make filling process continuous, intellectuality, automation, reduce the manual intervention in filling process, greatly improves filling efficiency and filling effect.
The technical solution used in the present invention is: a kind of catalyst automatic Loading method, its filling device comprises filler and control system two parts.Filler is made up of barrel, drive motors, transmission mechanism, distributing device, and described motor is arranged on barrel top, and distributing device is arranged on barrel lower end, and the two is connected by transmission mechanism, and transmission mechanism is arranged on barrel inside; Control system at least comprises one the touch-screen and of input control order can receive control instruction the controller be electrically connected with described motor.It is characterized in that described automatic Loading method in turn includes the following steps:
-get that to intend loading catalyst sample some, utilize filler to carry out filling and test, determine 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 according to this catalyst, determine distributing device diameter and corresponding charging rate;
-load parameter by touch-screen to control system input, comprise distributing device diameter, loading density, charging rate, loading height, consersion unit physical dimension etc.;
-control system controller calculates initial speed needed for distributing device and sends instruction, and drive motors operates;
-control system controller calculates the change of filling bed height automatically, and drive motors changes rotating speed constantly;
After-filling a period of time, shutdown detection, finds out actual filling situation and desired value obtains deviation, determines correction factor;
-by touch-screen Introduced Malaria coefficient, redefine rotating speed;
-filling device continues to run, and carries out automatic Loading;
-calculate loading height, reach preset value timer out of service, complete whole filling.
The present invention has following beneficial effect: this catalyst automatic Loading method can be applicable to the dense phase loading of differential responses container, variety classes catalyst, operability is high, control accurately, the needs of different filling environment can be met, can realize the serialization of filling process, automation, intellectuality,
Detailed description of the invention
Along with dense phase loading method applying in Catalyst packing industry, the filling of increasing consersion unit catalyst requires to adopt this dense phase loading method.Because various course of reaction is complicated, catalyst type is various, and filling requires also various, makes filling device be difficult to the same form hundred use.Therefore, the present invention devises following loading method, filling device distributing device is made into each series that diameter is different, simply replaces, and formulated a set of automatic Loading method with this, to meet different filling needs during application according to different demand:
Early-stage preparations: first ask for plan loading catalyst sample from customers' place some, carry out Physical Property Analysis, and utilize loader to carry out filling experiment, determine relevant filling parameter, as the relation of Flow-rate adjustment valve opening size and blanking velocity, the relation of distributing device rotating speed and loading density, the relation etc. between loading height and filling radius.Then according to the requirement such as loading density that client proposes, determine suitable distributing device, determine the charging rate adapted to simultaneously.These are operated in laboratory and complete, and carry out scene filling afterwards again.
On-the-spot filling: filler is arranged on reaction vessel top, connects control system, by touch-screen input filling parameter, comprises distributing device diameter, loading density, charging rate, loading height, consersion unit physical dimension etc.; Equipment runs automatically, determines initial speed, and drives distributing device to start to rotate, and mass transport is in filler barrel simultaneously, relies on gravity to move downwardly to distributing device, is shed away by material by the distributing device rotated.Along with the continuous increase of charge level height, control system automatically calculates required distributing device rotating speed and drive motors 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, determine correction factor and input system, control system redefines motor speed and relative speed variation according to new program, like this along with the rising of charge level, motor speed progressively improves, when charge level reaches predetermined loading height, equipment shuts down, and completes whole filling process.
Data preparation: after filling terminates, detect whole filling effect, record padding data, accumulates experience, suitably revises relative program, constantly improve this loading system.
