Specific implementation mode
The utility model provides a kind of combustion gas filter separator system, to make the purpose of this utility model, technical solution
And effect is clearer, clear, referring to the drawings and gives an actual example to the utility model further description.It should be appreciated that
Specific embodiment described herein is only used to explain the utility model, is not used to limit the utility model.
The utility model discloses a kind of combustion gas filter separator system that plant gas uses, for delivery of fuel gas into
Before entering gas electricity generator combustion power generation, the combustion gas is filtered and impurity detaches.One in the application is preferably implemented
In example, as shown in Figure 1, the combustion gas filter separator system includes air inlet 1 and gas outlet 2, wherein further include being arranged in institute
It states between air inlet 1 and the gas outlet 2, is linked in sequence, primary cyclone 3, two level for filtering the combustion gas
Inertia demister 4 and three-level fine filter 5, and the connection primary cyclone 3, the two level inertia demister 4 and institute
5 bottom of three-level fine filter is stated, the blow-off pipe 6 for the impurity filtered to isolate in the combustion gas to be discharged, the gas outlet 2
It is preferably arranged on the top of the combustion gas filter separator system.
In the combustion gas filter separator system, as shown in Fig. 2, the primary cyclone 3 includes connecting successively
Helical form inlet tube 31, taper pipe shaft 33, the helical form outlet 32 connect, and it is set to 33 lower part of taper pipe shaft, it is used for
Collect the vortex cover 34 and ash bucket 35 of the solid particle isolated in the combustion gas.The bottom of the ash bucket 35, passes through first row
Dirty mouth 36 is connected to the blow-off pipe 6.The primary cyclone 3 is used for will be in the combustion gas by cyclone centrifugal separation
Larger drop and solid particle is separated from gas.Its working principle is that：When the fuel gas flow containing impurity particles such as dust
With certain speed from the air inlet 1 is connected, with the taper pipe shaft 33 the tangentially-arranged helical form inlet tube 31 into
When entering the taper pipe shaft 33, because the speed of the fuel gas flow generally reaches 12-30m/s, it will be become from linear motion
The circular motion of spiral downlink, and in circular motion because solid particle or drop relative mass are larger, therefore inertia force also compared with
Greatly, it is easier to the tube wall of the taper pipe shaft 33 described in centrifugal bump, to lose its movement velocity and energy, and is made in gravity
It under, slides, is concentrated in the vortex cover 34 and ash bucket 35 along the tube wall, is discharged by the first sewage draining exit 36.
And the fuel gas flow is flowed to the air-flow drive at separator center after reaching 33 bottom of taper pipe shaft,
With the same direction continue former spiral downlink fuel gas flow center rotate, and because the taper pipe shaft 33 area contraction and
It is upward to be changed to rotation, and the primary cyclone 3 is left from the helical form outlet 32 being arranged on top.
In one of the utility model more preferably embodiment, in the combustion gas filter separator system, described
A bag hose or wet scrubber are connected with after helical form outlet 32, for capturing the fine grained in the fuel gas flow.Institute
Fine grained is stated, because of lighter weight, inertia is smaller, so failing to detach from the primary cyclone 3, but follows institute
It states fuel gas flow and leaves the primary cyclone 3.
It is described after the fuel gas flow leaves the primary cyclone 3 or the bag hose or wet scrubber
The solid particle polluter and drop carried in fuel gas flow will be substantially removed, to ensure that it is smooth that next step is separated by filtration
It carries out.
Then the second inlet tube 41 that the fuel gas flow is arranged from 4 lower sidewall of two level inertia demister enters institute
It states in two level inertia demister 4, in a preferred embodiment, the two level inertia demister 4, preferably wire mesh demister,
It includes the silk screen block 43 being made of silk screen and silk screen grid, and the supporting structure for fixing the silk screen block 43, is used for
It is acted on by inertial collision, gas, liquid and the solid in the combustion gas is further detached.
The silk screen block 43 can be the gas-liquid filter net of various materials, by wire or nonmetal wire with wettability
Composition.The wire mesh demister can filter out the larger liquid foam to suspend in the fuel gas flow, and smaller and small liquid foam.
When the fuel gas flow with liquid foam with certain speed uplink by the two level inertia demister 4 when, liquid foam therein
It is adhered to colliding with the silk screen block 43 in the filament surfaces of the silk screen block 43.With the liquid foam diffusion and
Gravitational settling will form larger drop, the junction of two filaments be flowed to along the filament of the silk screen block 43, described
Under the collective effect of the capillarity of the wettability of filament, the surface tension of liquid and the filament, the drop is increasingly
Greatly, when the drop of aggregation arrives greatly climbing power and its own surface tension of liquid of the gravity of itself more than the fuel gas flow
When resultant force, just separation falls to demister bottom 44 to the drop from the filament, then flows out to its institute from second outlet 46
The blow-off pipe 6 of connection.
And the fuel gas flow is then after further purification, from the foam removal being arranged above the two level inertia demister 4
42 outflow of device outlet.
The wire mesh demister is to the liquid foam of grain size >=3 ~ 5um, and arresting efficiency reaches 98%-99.8%, and gas passes through foam removal
Pressure drop very little after device, only 250-500Pa, this is conducive to the production efficiency for improving equipment.
Then the fuel gas flow flows into described three from the third inlet tube 51 for being set to 5 lower part of three-level fine filter
In grade fine filter 5, during uplink, receiving is further separated by filtration.The three-level fine filter 5 includes an at least refined filtration core
53, it is set in refined filtration pipe 55, the refined filtration core 53 is used to filter out 10 microns or more of solids and collection cut size is small
Then spray, the spray are condensed into drop, and be settled down to the bottom 54 of the refined filtration pipe 55, then export 56 from fine filter
It is expelled in the blow-off pipe 6.
And the fuel gas flow flows out combustion gas filter separator system then after further purification from the gas outlet 2
System, enters back into the gas electricity generator, combustion power generation.
Combustion gas filter separator system provided by the utility model, by between the air inlet and the gas outlet
The combustion gas is being sent into combustion gas by primary cyclone, two level inertia demister and the three-level fine filter of serial order setting
It before generator, is further filtered, detaches liquid therein and solid impurity, maximumlly remove the impurity in natural gas
Ingredient ensure that the safety and stability of the gas electricity generator operation to improve utilization ratio of the plant gas to natural gas,
The service life for extending fuel gas generation equipment improves the economic benefit of fuel gas generation enterprise.
It should be understood that the application of the utility model is not limited to above-mentioned citing, those of ordinary skill in the art are come
It says, it can be modified or changed according to the above description, and all these modifications and variations should all belong to the appended power of the utility model
The protection domain that profit requires.
