The utility model proposes a kind of enriched layer expansion chamber, comprise that enriched layer draws bend, this enriched layer is drawn bend and is comprised that gas inlet port, gas sends mouth, it is characterized in that, comprise that also one draws the solid collection case that bend communicates with enriched layer, the solids fluid layer is through introducing the outer solid collection case of bend because action of centrifugal force forms enriched layer behind the bend, and the solid collection case enters the back solid particles sediment for the solid enriched layer and uses.
The interior profile that described enriched layer is drawn bend can be concentric circles or non-concentric circles, also can be form concentric spirals line or non-form concentric spirals line.
Described enriched layer draw in the bend bend cross section between profile can be circular, oval, drip shape, square, rectangle or rhombus; The cross section can be uiform section or variable cross-section.
Described enriched layer is drawn bend and is provided with solid enriched layer outlet, and this solid enriched layer outlet is communicated with the solid collection case; The shape of solid enriched layer outlet can be arc, triangle or rectangle, and solid enriched layer outlet is the easement road airflow direction opening that facings the wind.
Described solid collection case has a solid particle ash-removing mouth.
The solid particle ash-removing mouth of described solid collection case is positioned at the bottom of solid collection case.
Describedly be provided with gas discharge channel in above the solid collection case or the ashless space above the side.
It is circumference bend or spiral bend that this described enriched layer is drawn bend.
Described solid enriched layer outlet can be provided with one or more, in be provided with high-temperature and wear-proof.
Described enriched layer is drawn bend, solid enriched layer outlet and solid collection case and is adopted metal material to make peripheral hardware adiabator layer and metal casing.
The utlity model has following advantage: the utility model needs the solid enriched layer in the two phase flow of pre-separation to be completed into by making on a curved pipe, enter the solid collection case by solid enriched layer outlet, and collect in the outside gathering-device through the solid particle ash-removing mouth of solid collection case.Pass through enriched layer expansion chamber of the present utility model, solid matter is removed in separation at the beginning of the solid phase particles of Dual-Phrase Distribution of Gas olid carries out, thereby avoids may causing because of solid matter the wearing and tearing of equipment.The utlity model has lower resistance, high efficiency.
[Figure of description]
Fig. 1 is the structural representation of enriched layer expansion chamber of the present utility model.
[most preferred embodiment]
As shown in Figure 1, enriched layer expansion chamber of the present utility model comprises that enriched layer draws bend 1 and solid collection case 2.
It is a bend that enriched layer is drawn bend 1, and it comprises that gas inlet port 11 and gas sends mouthfuls 12.The interior profile that enriched layer is drawn bend 1 can be concentric circles or non-concentric circles, also can be form concentric spirals line or non-form concentric spirals line.This bend can be the circumference bend, also can be the spiral bend.
Enriched layer draw bend cross section between the interior profile of bend 1 can be circular, oval, drip geometries such as shape, square, rectangle or rhombus.The cross section can be uiform section and variable cross-section.
Enriched layer is drawn bend 1 and is provided with solid enriched layer outlet 3, the outlet shape can be geometries such as arc, triangle, rectangle, outlet 3 is the easement road airflow direction openings that facing the wind, and described outlet 3 is offered at the solid enriched layer place of being completed into of circumference or helical pipe.Described solid enriched layer outlet 3 can be one or more, in the pipeline at outlet 3 places the certain thickness high-abrasive material is set.
The solid enriched layer that solid enriched layer outlet 3 is drawn enters solid collection case 2, and solid collection case 2 enters the back solid particles sediment for the solid enriched layer and uses.
Be provided with gas discharge channel 5 in above the solid collection the case 2 or ashless space above the side, bringing gas flow into when the cross-sectional sizes of passage 5, shape are introduced solid collection case 2 according to the solid enriched layer is basis.Passage 5 is in when design, should notice that ash does not deposit or can deashing, and the gas of following the solid enriched layer to draw is emitted by gas discharge channel 5 is set by solid collection case 2.The gas of gas discharge channel 5 outlets of process solid collection case 2 can directly be introduced the place that operation requires introducing, also can separate again.Separate mode can be to separate by other piece-rate systems again, also can introduce bend and together separate with inlet gas.
Enriched layer of the present utility model is drawn the type expansion chamber, be used for the sedimentation of gas-solid two-phase air-flow, just separate, its separate mode is: before gas-solid two-phase air-flow enters solid collection case 2, be introduced into one section bend 1, in bend 1 in the flow process, after part solid enriched layer is completed in the two phase flow, be subjected to the impact of two-phase air-flow impulse force and the influence of centrifugal force, by interference-free, the solid enriched layer outlet 3 of complete introducing bend 1 and enter solid collection case 2, dust particle that can sedimentation in solid collection case 2 is by sedimentation, the air communication that the particle that can not be subjected to gravitational settling is introduced with the solid enriched layer is crossed gas discharge channel 5 and is drawn outside the solid collection case 2, other deals with, and processing mode is not in the utility model.
Described enriched layer is drawn bend, solid enriched layer outlet and solid collection case and is adopted metal material to make, as required peripheral hardware adiabator layer and metal casing.
