Description
Technical field
The utility model is related to field of olefin polymerisation, more particularly, to a kind of charging of granular solids polyolefin catalyst
System.
Background technology
The catalyst majority applied to olefinic polyreaction industrial at present is solid particle type, and this solid particle type is urged
The charging of agent is generally added using the catalyst feeding device of particular design, such as is used on Unipol polyethylene devices
Solid catalysis agent feeding device；It is also a kind of by complicated process for preparation, by catalyst preparation into certain density slurries or
Paste, then send into reactor with metering system.Both the above method, the former equipment investment is very high, and adition process is easily blocked up,
The amount of catalyst in catalyst feeder is known without accurately and effectively method.The process for preparation of the latter is extremely complex, single
The preparation of catalyst is accomplished by ten more than hour, and catalyst brings slurries or paste into reaction system, to reaction system
Have an impact.
Polyolefin catalyst generally has very high activity, requires catalyst with sufficiently stable and accurate in practical operation
The minimum flow of control is added in polymer reactor, and it is unstable otherwise to will result in polymerisation, causes product quality to fluctuate
Or the caking in reactor.Therefore, it is the key for needing to solve how catalyst to be added into polymerization reaction system uniformly, exactly
Problem.In addition the poor fluidity of solid olefins polymerization catalyst, cohesive easily in catalyst storage tank to unite or formed bridge formation, is catalyzed
Agent can not be added in feeding line by automatic valve, cause catalyst can not continuous feed, reaction be forced stop.
Chinese patent CN101786552A discloses a kind of powder material autoweighting feeder, including charging hopper, plus
The outlet of funnel connects the entrance of metering ball valve, measures in the material channel of ball valve provided with determination capacity and rotary storage
Expect room, the outer wall of storage compartment is against the inwall of the material channel of metering ball valve, and in storage compartment's rotation process, material import and export can
It is connected with the entrance or outlet for measuring ball valve.The utility model can realize the powder feed of low dose, but material is easily in thing
Expect the inwall deposition of passage, cause error in dipping.
Chinese patent CN101811011A discloses a kind of automatic catalyst-feeding method, set fluidisation conveying airduct line to
It is continually fed into feeder on fluidisation conveying wind, fluidisation conveying airduct line and fluidisation conveying wind regulating valve and flowmeter, charging is set
Charging regulating valve is set on pipe, sets one to connect between the pipeline section of outlet valve near exit with discharge nozzle at the top of feeder
Valve and blast regulating valve are communicated with pipe, communicating pipe, fluidisation conveying wind is constantly passed through into feeder, catalyst is in charging
Circulated in connection circulation loop at the top of device, reduce the deposition blocking during catalyst transport, feed unstable asks
Topic, but the EGR of the equipment is arranged on feeder top, and very strong fluidisation conveying wind, the device one are needed in cyclic process
As use compressed air as fluidisation and convey wind, therefore equipment cost is higher, and the utility model is also required by fluidizing conveying
Wind ensures that pressure is constant less than or equal to catalyst storage tank pressurising pressure, higher than regenerator pressure, so to equipment in feeder
Requirement it is higher, add production cost.
Chinese patent CN102993342 A provide a kind of charging system of powdery polyolefin catalyst.The system includes urging
Agent storage tank, pans and blower fan, catalyst storage tank are connected by pipeline with pans, and an automatic valve, wind are set on pipeline
The gateway of machine at the top and bottom of pipeline and pans respectively with being connected to form on circulation loop, pipeline at the top of the pans
Position sets outlet, is connected by pipeline with rear system.The automatic valves of two series connection are set above the line under the overall leadership being connected with rear system,
One quantity tube is set between automatic valve；One gas blow line is set respectively in the outlet of two automatic valves.The practicality is new
Solid catalyst can be added continuously in reaction system by type at ambient pressure, but due to lacking the metering device of catalyst, be urged
The addition of agent is uncontrollable.And this charging system uses a catalyst storage tank and a pans, catalyst charging
Long flow path, catalyst is easily enriched with and remained in pans, causes the waste of catalyst.
Different types of catalyst often poisonous substance each other.If device need switching the trade mark when, it is necessary to thoroughly remove catalyst
Charging system, is now accomplished by dismantling catalyst feed systems.Polyolefin catalyst is former using poisonous and hazardous transition metal
Son is as the activated centre of catalyst, the alkyl aluminium component often not waited containing quantity in solid polyolefin hydrocarbon catalyst in addition,
Meeting can vigorous combustion after air.When switching catalyst, it is enriched with such as in catalyst storage tank, not only results in environmental pollution, also
Operating personnel can be caused with personal injury, trigger serious accident.Existing catalyst addition system is pressure vessel, is torn open
Unload process cumbersome and time-consuming.The usual residence time of polyolefin catalyst in the reactor is 30 minutes to 2 hours, and this just anticipates
Taste must complete as early as possible in the unloading process of catalyst feed systems.And in existing gas-phase polythene commercial plant,
The raw materials such as ethene, co-monomer, nitrogen and solid catalyst need to be continuously added into gas-phase fluidized-bed reactor, if feed system
Take-down time is long, will result in a series of serious consequences such as reactor superpressure, raw material are largely vented, device stops.And it is industrial
Device is big due to scale, and the loss that each driving and parking is caused is also millions of levels.And the key for switching the trade mark is exactly two kinds of catalysis
The Rapid replacement in charging system of agent system.Therefore in the urgent need to one kind catalysis can be switched fast without stopping polymerisation
The catalyst addition system of agent system.
In addition, the existing high-end trade mark or temperature sensitive type solid polyolefin hydrocarbon catalyst are in fill process, feeding temperature needs dimension
Hold at 0~30 DEG C.The fluctuation of feeding temperature can influence the performance of catalyst and its polymerizate, cause polymerizate quality ripple
It is dynamic, and then influence the benefit of manufacturing enterprise.And the charging system of existing solid polyolefin hydrocarbon catalyst is without temperature regulating device.Cause
This is in the urgent need to a kind of continuous charging of solid polyolefin hydrocarbon catalyst and online switching system.The utility model utility model is consolidated
The charging system of body polyolefin catalyst, increases by an agitator on catalyst storage tank, one temperature regulating device of outside increase, both can be with
The blanking temperature of stability contorting catalyst, can avoid catalyst from bonding and unite or formed bridge formation again.It is real using the utility model
With the charging system of new solid polyolefin hydrocarbon catalyst, simple in equipment, catalyst charging flow is short；Per depot siding and valve
Door is purged and conveyed by gases at high pressure, enrichment and residual in the absence of catalyst；Both being produced into for polyolefin had been saved
This, is easy to the maintenance maintenance of equipment again.The utility model also helps different types of catalyst and switched online, saves polyolefin
The driving cost of commercial plant, it is to avoid the generation of Transition Materials.
