Description
Technical field
This utility model relates to coal chemical technology, in particular to a kind of cyclone separator and polyolefin production system.
Background technology
Polyolefin device produce molten polymer through extruding after pelletizing, pelletized polyolefin with water for carrier through granule induction system
Deliver into pellet dryer, be dehydrated in exsiccator laggard enter feed bin.It is dried and by contacting with granule, aqueous is gathered with air
Polyolefin pellets is dried, containing a certain amount of fuel gas (such as: the ethylene of particle entrainment and propylene etc.), dust (granule cutting and
Course of conveying produces) and the dry removing gas of water enter cyclone separator and separate, (the removing polyolefin of gas after separation
Dust and water) send catalytic oxidation unit to carry out catalytic oxidation treatment after induced-draught fan compresses.Wherein, as it is shown in figure 1, whirlwind divides
Include from device: 1 ', housing；11 ', gas access；12 ', gas outlet；13 ', flushing water entrance；14 ', discharge gate；15’、
Material-level detecting device；3 ', blow-off valve.Wherein, A ', expression flushing water water source, B ', expression catalytic oxidation unit.
The process and the cyclone separator dust emission that are dried removing gas generally have two kinds of designs.It is dried the process of removing gas,
When before 21st century, environmental requirement is the strictest, its design is: is dried removing gas and directly arranges after cyclone separator separates
Enter air；Enter 21st century, along with the enhancing of environmental consciousness, country to the close inspection of gas discharge standard and execution,
Adding the catalytic oxidation unit of exhaust-gas treatment in design, removing gas send catalytic oxidation unit to carry out being catalyzed oxygen after cyclonic separation
Change reaction, the organic alkene contained in waste gas is converted to carbon dioxide and water.Corresponding cyclone separator dust emission also has two
Planting design, the process being dried removing gas corresponding to the first, the isolated dust of cyclone separator is direct when device is stopped work
Discharging on the spot, because dust emission is irregular, interval time is longer, enters in the gas of air containing a certain amount of dust.Correspond to
The second is dried the process of removing gas, because of catalytic oxidation unit catalyst to fuel gas and dust content requirement strict (general require≤
20mg/m3), therefore removing gas must separate totally, and cyclone separator must periodically carry out dust emission.Its dust emission is general
The design using separator water filling to rinse, is taken out of dust by flushing water.
The dust of existing separator rinses and discharge design is: after expecting in separator that position reaches necessarily, by the moisturizing of separator top
Moisturizing opened by valve, and bottom discharge valve is opened discharge simultaneously, and benefit limit, limit is arranged.There are the following problems in existing design: 1. flushing water punching
Wash less than dust on separator tank skin, when rinsing with discharge, the dust of separator center can only be rinsed out；2. because of tank
The punching of wall dust can't is washed off, and material-level measure is in alarm condition all the time, it is impossible to judge opportunity and the discharge situation of discharge；3. separator
Bottom discharging mouth is frequently occluded when discharge, and discharge is the most smooth；4. substantial amounts of flushing water is needed gradually to rinse and carry secretly during discharge,
Flushing water waste is big.
The existence of the problems referred to above had both disturbed the judgement of discharge time, also makes discharge clean and causes discharging gas dust content greatly,
Causing catalytic oxidation unit cycle of operation short and catalyst life is short, also result in the waste etc. of a large amount of flushing water, these problems are always
Annoying polyolefin device technical staff, it would be highly desirable to solve.

Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the application and the feature in embodiment can be mutually combined.
Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As background technology is previously mentioned, in existing cyclone separator, still suffer from dust emission thoroughly and the blocking of dust emission mouth,
Drain time can not be determined in time, cause discharge gas dust content big, not only affect catalytic oxidation unit cycle of operation and catalyst
In the life-span, also result in the technical problems such as a large amount of flushing water wastes.
For improving above-mentioned condition, existing cyclone separator is studied by applicant, finds that existing dust rinses and exhaust system
There are two defects in design: one) the pouring-in design of flushing water is unreasonable.Original design flushing water pipeline is directly from separator top
Portion enters, and after flushing water enters separator, is equivalent to pour water in separator, relies on the flowing of water disperse and drive dust,
Thus tank skin dust can not be rinsed out.Two) separator discharge gate 14 ' and blow-off valve 3 ' size design are unreasonable.Original design discharge
Mouth 14 ' and blow-off valve 3 ' size are less than normal, and dust is easily piled up in discharge gate 14 ' and blow-off valve 3 ' place, cause dust discharge smooth, punching
Wash water consumption is big.
For two defects of the original design existence of cyclone separator flushing water and discharge system, two kinds are taked to arrange the most targetedly
Execute and improve: one is, flushing water shower nozzle is improved, water filling change large area water spray into.Two are, increase discharge gate 14 '

Being difficult to pile up at material mouth 14, dust discharge is smooth and easy, and flushing water consumption also greatly reduces.
Preferably, above-mentioned cyclone separator also includes that material-level detecting device 15, material-level detecting device 15 are arranged on the sidewall of housing 1
On.
In order to detect the amount of the particulate dust separated in housing 1 more accurately, thus realize regular discharge more in time,
In above-mentioned preferred embodiment, housing 1 sidewall arranges material-level detecting device 15, with material in monitoring housing 1 in real time
How much, the timely discharge of regulation in real time and particulate dust to instruct flushing water consumption.
Preferably, material-level detecting device 15 includes that the first material-level measure table and the second material-level measure table, the first material-level measure table are arranged
In the upper portion side wall of housing 1, the second material-level measure table is arranged on the lower sides of housing 1.
In above preferred embodiment, the various location in the top and the bottom of the sidewall of housing 1 respectively arranges a material-level detecting device
15, such as material-level measure table, top can be high charge level detect table, in bottom can be low material-level measure table, with from
The diverse location detection particulate dust of housing 1 number, thus coordinate consumption and the discharge of discharge gate 14 of flushing water more accurately
Between relation, thus not only improve cyclone separator operation stability, and the content of dust in gas after being substantially reduced separation,
And then extend cycle of operation and catalyst service life of subsequent catalyst oxidation unit.
Preferably, flushing water entrance 13 is arranged in the upper portion side wall of housing 1.
In this utility model, the setting to flushing water entrance 13 there is no particular/special requirement, if beneficially flushing water distributor in housing 1
2 on cavity inner wall, uniform sprinkling can (such as can be arranged on roof or sidewall).In above preferred embodiment, will rinse
Water inlet 13 is arranged in the upper portion side wall of housing 1, compared to existing technology in be arranged on roof, reduce the relatively high of entrance
Degree, the relative reduction pressure at flushing water water source.
