Description
Technical field
This utility model relates to a kind of flue gas turbine rotor dust arrester, surpasses online particularly to a kind of flue gas turbine rotor
Sound dust arrester.
Background technology
Catalytic cracking flue gas turbine fouling at present is a unavoidable problem, due to upstream cleaner efficiency of dust collection
Limited, cause part small particle fine powder to enter cigarette machine.Work in many reasons such as temperature, pressure, moisture, catalyst self properties
Under with, catalyst can deposit and fouling in the blade of cigarette machine and leaf road, can destroy the dynamic of cigarette machine rotor after long-play
Balance, causes vibration values to be aggravated, even more so that leaf destruction.This abnormal operation operating mode can only be by switching the stream of flue gas
To, walk double slide valve blood pressure lowering orifice plate, enter air through waste heat boiler, chimney, slatterned most energy, resulted even in
The emergency shutdown of whole device.The fouling of flue gas turbine expander is the most insurmountable domestic and international difficult problem, and can only be by being taken turns by flue gas
Machine is stopped work and is dismantled and could clear up the fouling of catalyst on rotor, and also needs rotor does follow-up maintenance work after cleaning
Make, costly, waste time and energy, affect normal process process.
Accordingly, it would be desirable to design one can suppress catalyst fouling on rotor according to different operating modes, and to flue gas
Turbine runs well affects the device of little online dedusting.
Utility model content
This utility model aims to solve the problem that the problems referred to above, it is provided that a kind of online ultrasonic dust arrester of flue gas turbine rotor, adopts
With online ultrasonic dust collection method, make cigarette machine inside smoke vibrate, remove Rotor Scaling Formation, little to the interference of cigarette machine interior flow field, not shadow
Ring the carrying out of normal production technology.
To achieve these goals, this utility model is by the following technical solutions:
A kind of online ultrasonic dust arrester of flue gas turbine rotor, it includes the ultrasonic cleaner unit 1 that four circumferences are evenly arranged,
Ultrasonic cleaner unit is made up of supersonic generator 1.1, sealing ring 1.2, supersonic generator probe 1.3.Supersonic generator 1.1
Being arranged on cigarette machine shell, described supersonic generator 1.1 is provided with supersonic generator probe 1.3, supersonic generator
It is tightly connected by sealing ring 1.2 between probe 1.3 and shroud 2.
Pop one's head in 1.3 axis and shroud 2 of supersonic generator radially becomes 10 degree of angles, yawing moment and rotor direction of rotation one
Causing, outside is wrapped up by exotic material.
This utility model has the advantage that employing ultrasound wave makes flue gas turbine expander inside smoke generation dither, peels off
Rotor Scaling Formation, stops catalyst deposition on rotor, has and does not affects technique production, suppresses catalyst deposit fouling, to cigarette
Machine flow is little, energy-saving and cost-reducing, increases the advantages such as income.

With example, this utility model patent is described further below in conjunction with the accompanying drawings:
As Figure 1-3, a kind of online ultrasonic dust arrester of flue gas turbine rotor, it includes what four circumferences were evenly arranged
Ultrasonic cleaner unit 1, ultrasonic cleaner unit is made up of supersonic generator 1.1, sealing ring 1.2, supersonic generator probe 1.3.Super
Sonic generator 1.1 is arranged on cigarette machine shell, and described supersonic generator 1.1 is provided with supersonic generator probe 1.3,
It is tightly connected by sealing ring 1.2 between supersonic generator probe 1.3 and shroud 2.
Pop one's head in 1.3 axis and shroud 2 of supersonic generator radially becomes 10 degree of angles, yawing moment and rotor direction of rotation one
Causing, outside is wrapped up by exotic material.
Specific works mode: first install device,
1) flue gas turbine expander catalyst inlet gas concentration, catalyst grain size distribution are measured；
2) operating frequency of supersonic generator (1.1), ultrasonic frequency, dedusting time are set:
Catalyst inlet gas concentration is 0～50mg/m3, particle diameter more than 10 μm catalyst volume fraction < 1%, then set super
Frequency of sound wave is 20KHz, and the dedusting time is 20min/ time, 3 times/day；
Catalyst inlet gas concentration is 50～100mg/m3, 1% < particle diameter more than 10 μm catalyst volume fraction < 2%, then
Setting ultrasonic frequency as 30KHz, the dedusting time is 40min/ time, 3 times/day；
Catalyst inlet gas concentration is 100～1000mg/m3, 2% < particle diameter more than 10 μm catalyst volume fraction < 4%,
Then setting ultrasonic frequency as 40KHz, the dedusting time is 60min/ time, 3 times/day.
Supersonic generator (1.1)Formula rotor Speed unit is: turn
Number/the second.
3) flue gas generation dither is made, to operating flue gas turbine rotor by supersonic generator probe (1.3)
Carry out scale removal.
Below by way of example this utility model is illustrated, but this utility model is not limited to above-mentioned being embodied as
Example, all any changes done based on this utility model or modification belong to the scope that this utility model is claimed.
