Accompanying drawing explanation
The structural representation of the meticulous foam removal sand removing separator of Fig. 1 High-efficiency Gas of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, with specific embodiment, the meticulous foam removal sand removing separator of High-efficiency Gas of the present utility model is further elaborated.Should be understood that following examples only for illustration of the utility model but not for limiting scope of the present utility model.
As shown in Figure 1, the meticulous foam removal sand removing separator of High-efficiency Gas of the present utility model comprises a tank body 7, the bottom of described tank body 7 is gravity settling chamber 10, the central authorities of gravity settling chamber 10 are provided with cyclone separator 3, gas foam removal sand filter 5 is provided with above the outlet of cyclone separator 3, the air inlet 4 of the meticulous foam removal sand removing separator of described High-efficiency Gas is arranged at the bottom of tank body 7, straight-through gravity settling chamber 10, exhaust outlet 8 is arranged at the top of tank body 7, is positioned at the top of gas foam removal sand filter 5.Like this, when the meticulous foam removal sand removing separator work of High-efficiency Gas of the present utility model, the path that flows through of natural gas is: first natural gas enters gravity settling chamber 10 from the air inlet 4 of tank body 7 bottom, then cyclone separator 3 is entered, from cyclone separator 3 out after enter gas foam removal sand filter 5 again, the exhaust outlet 8 finally above filter 5 is discharged.
In the present embodiment, described gas foam removal sand filter 5 is provided with two-layer filter box, and this two-layer filter box is setting up and down, is all filled with doughnut in upper and lower two-layer filter box, preferably 7 ~ 13 hole doughnuts.Doughnut in filter box is arranged by density gradient layering from bottom to top, concrete, the doughnut density of lower floor or porosity minimum, more increase step by step toward upper layer density or porosity, become fine and close, form three-dimensional filtration.In practical application, different filtering accuracy grades can be arranged to as required, to guarantee the cleanliness factor filtering rear gas.Those skilled in the art will readily understand, although the present embodiment employing is two-layer filter box, can arrange more multi-layered filter box according to actual needs, this is apparent.
Because the elasticity of doughnut is large, better tolerance, to the excellent adsorption of mist and gravel, add that top-down density gradient is arranged, mist and gravel can by automatic classifications, first the mist that particle diameter is larger or gravel can be trapped, then be trapped from big to small by particle diameter successively, thus realize three-dimensional filtration; Because mist and gravel are always walked toward the place that resistance is less, therefore, along with the carrying out of filtering, a kind of balance can be formed gradually in plane, and then spatially form a kind of balance, therefore the pneumatic filter of this structure has the advantages such as high efficiency, lower resistance, stable and reliable operation, high pollutant holding capability.What is more important, compared to common filter, the time that its resistance is formed extends greatly, the most obvious benefit brought thus is, the filter medium that previous needs are often changed, half a year more than can be extended to after adopting filter of the present utility model to change again, can realize synchronous with the conventional time between overhauls(TBO) of equipment, greatly reduce costs.And, because filtering material adopts to arrange by density gradient layering, to a certain degree need with when changing when filtration resistance rises to, without the need to whole filter is removed, and only need filter course wherein to take out to change, usually only need within 2-3 hour, can complete, time saving and energy saving.
The meticulous foam removal sand removing separator of High-efficiency Gas of the present utility model, intermediate collector sand room 12 is provided with below described tank body 7, the bottom of cyclone separator 3 is connected to described intermediate collector sand room 12 by pipeline, the gravel of separation and liquid impurity to be delivered in intermediate collector sand room 12; And pipeline is provided with ball valve 14, when needing the impurity in intermediate collector sand room 12 to discharge, ball valve 14 can be closed, to discharge impurity when uninterruptedly producing; And cushioning effect can be played in intermediate collector sand room 12.The bottom of intermediate collector sand room 12 is provided with blow-off pipe 13, discharges for the impurity that will collect.In addition, intermediate collector sand room 12 is also provided with liquid level gauge 2, for observing the amount of collected impurity in intermediate collector sand room 12, to determine whether to need to open blow-off pipe 13 blowdown.
As shown in the figure, be also provided with pressure measuring system 9 in tank body 7, this pressure measuring system 9 has two monitoring points, lay respectively at air inlet 4 and exhaust outlet 8, for being detected the pressure reduction between filter 5 import and export, to monitor the rising situation of resistance, and when needs, filter 5 is changed.
During natural gas foam removal desanding, natural gas enters gravity settling chamber 10 larger in tank body 5 by the air inlet 4 set by tank body 7 side, now gas flow rate lower (about 0.8 ~ 1.5m/s), therefore the bulky grain (particle diameter is more than 150 ~ 200 μm) in gas, can be separated due to particles settling effect, fall into the bottom of tank body 7; Gas is after gravity settling chamber 10 pretreatment, and enter built-in cyclone separator 3 and carry out second level process, in this process, the mist gravel of 20 μm is separated and enters into liquid collecting sand room; Enter into gas foam removal sand filter 5 through the natural gas of primary treatment simultaneously and carry out second level process, after the many casings metre filter of the second level, can by more than 5 μm mists in gas and gravel removing.Gas after the second level is filtered is discharged by tank body gas vent 8.
