Below in conjunction with the embodiment accompanying drawing the utility model is described further.
Fig. 1 is the example structure schematic diagram.
Among the figure: 1, mist eliminator; 2, fairing; 3, inlet air inlet adjusting device; 4, mixture intake; 5, the anti-whirlpool of outlet device; 6, bearing; 7, solid, liquid outlet; 8, liquid level regulator; 9, declining liquid tube.
The specific embodiment
Embodiment as shown in the figure, this eliminator adopts the vertical multi-stage isolating construction, tank body is a vertical type cylinder jar shape structure, and it comprises mist eliminator 1, fairing 2, inlet air inlet adjusting device 3, the anti-whirlpool of outlet device 5, declining liquid tube 9, mixture intake 4, liquid level regulator 8, solid, liquid outlet 7, bearing 6.This eliminator is divided into mist eliminator, rectification chamber, centrifugation chamber, four parts in liquid storage district from top to bottom, and the outer end, top of tank body is fixedly connected with mist eliminator 1, and mist eliminator 1 is made up of one group of mesh pad, drop filter and gas vent.Mist eliminator 1 is small-sized tubular construction, is welded on the top of compound eliminator cylindrical shell, and the lower end has through hole to be communicated with tank body, and the upper end is a flange arrangement; Mesh pad and drop filter are fixed on the small rack, are welded in the mist eliminator cylindrical shell again, and gas outlet is equipped with the anti-whirlpool of outlet device 5 in mist eliminator 1 is simplified.Mist eliminator 1 gas vent is a short tube, is welded on mist eliminator 1 top flange formula end socket top, and is fastening with the sealing of silk screen end flange.Below, the middle part of tank body one side is connected with mixture intake 4, and the tank body opposite side below corresponding with import 4 is connected with liquid level regulator 8, and the outer end, bottom of tank body is connected with solid, liquid outlet 7, has bearing 6 to support under the tank body.The tank body internal upper part is the rectification chamber, fairing 2 is installed, is used for capturing the fine droplet that carries in the uprising gas of centrifugation chamber (diameter＞0.2mm), and compiling after declining liquid tube 9 flows into the liquid storage districts, fairing 2 is the integral body of one group of corrugated sheet preparation, is fixedly welded in the cylindrical shell of rectification chamber.The middle part is the centrifugation chamber in the tank body, is made of mixture intake 4, inlet air inlet adjusting device 3, declining liquid tube 9.The centrifugation chamber is welded with support in simplified, fix inlet air inlet adjusting device 3, declining liquid tube 9 with welding manner again on support.The effect of centrifugation chamber is that solid in mixture intake 4 air inlets and liquid are carried out centrifugation, and uprising gas is adjusted, and prevents gas-entrained liquid.Declining liquid tube 9 effects are that the liquid that rectification chamber, top traps is compiled guiding liquid storage district, back, prevent that uprising gas from carrying back fairing 2 with it.The bottom is that the liquid storage district is made of liquid level regulator 8, the anti-whirlpool of outlet device 5, solid-liquid outlet 7 in the tank body, is used for storing and isolates solid and liquid in the gas.Liquid level regulator 8 usefulness flanges are fixed on the cylindrical shell flange, and the anti-whirlpool of outlet device 5 is directly welded in the upper port of cylindrical shell bottom solid, liquid outlet 7.Liquid level regulator 8 is used to refer to the height of liquid storage district liquid level, thereby whether decision discharges; Device 5 effects of the anti-whirlpool of outlet are to form eddy current when stoping discharge opeing, and gases at high pressure are carried out.
Operating principle of the present utility model:
Gas (liquid hydrocarbon, water, impurity, gas etc.) mixture, is carried out gas-liquid mixture just to separate from tangentially entering in the tank body equipment by centrifugation by the mixture intake 4 that is arranged on the tank body middle part.
Gas after just separating moves upward, and carries out rectification through the 2 pairs of gases of fairing that are arranged on tank body top, to satisfy the requirement of gas-liquid separation.Its effect mainly is that gas-liquid is carried out final separation, selects big, good to the wettability of the liquid material filling type structure of specific area for use according to its function and effect.It is applicable to the last separation of the mixture that liquid content is low, solid content is little.At this, the less hanging drop of diameter fairing 2 surfaces obtain capturing and run foul of each other assemble after, drop down the anti-whirlpool of outlet device 5, solid, liquid outlet 7, liquid level regulator 8 in the liquid storage district of equipment by catheter, the gas after handling through fairing continues to flow to outlet mist eliminator 1.
Structure of the present utility model is not only limited in the above-described embodiments, as long as in outlet mist eliminator 1, be provided with rectifier cell and catch the mist element, and be provided with gauze pad demister and drop filter element, adopt removable, changeable type, design by circulation flux and precision is preferred, guarantees that demist efficient and life cycle get final product.The gauze pad demister is as the first order resolution element of equipment outlet mist eliminator 1, and main effect is to remove the drop of particle diameter greater than 1 μ m, and the drop filter element is all removed particle diameter greater than the drop of 0.2 μ m.Gas is through mist eliminator 1 outlet effusion equipment, and the liquid in liquid storage district (5 7 8) is regulated the back by liquor-level regulator 8 and exported 7 outflow equipment by solid, liquid, finishes the gas-liquid separation process.Because the density of solid particle is greater than liquid, so the separation of solid particle is similar to liquid, and easier than liquid.Export 7 places at solid, liquid and be provided with the respond well anti-whirlpool of plate and frame outlet device 5, to stop " reentrainment " phenomenon of liquid outlet.
Conventional liquor-level regulator has mechanical type, pneumatic type and electrodynamic type.Except that the mechanical type liquor-level regulator, pneumatic type and electrodynamic type liquor-level regulator need the secondary meter combination to finish the adjusting and the control function of liquid level.Control to equipment, consider that this installs occasion use in the open air, for the benefit of produce and manage, so this project will adopt electronic liquor-level regulator, this adjuster organically combines secondary meter and primary instrument (electric operator), can realize teletransmission control, the adjusting of liquid level; In addition,, also be provided with one and overlap formula liquid level meter on the spot, realize the demonstration on the spot of liquid level for convenient management.One cover telemetering type liquor-level regulator and is set overlaps formula liquid level meter on the spot, be installed in the liquid level place, control and regulate gas-liquid interface by liquor-level regulator, stable gas-liquid interface and separating flowing field are arranged, and can realize teletransmission control, adjusting and the demonstration on the spot of liquid level with assurance.
