Description
Affiliated technical field
The utility model relates to a kind of chemical filtration separation equipment, especially solid filtering, gas and the fluid separation applications in applicable craft gas, the virgin gas.
Background technology
At present, known gas-liquid separator is made up of pressure vessel and intraware silk screen.Expand by means of gas in the separator of big volume, rely on the fluid gravity inertial to separate the bulky grain drop, utilize again the intraware silk screen by contact, interception, collision to finish separation.Flow out separator and in system, circulate because efficiency separator is low, cause designing in the output 10% droplet, cause not only that product runs off, the product net value reduces, reduce plant capacity, and make the side reaction aggravation, cause unstripped gas consumption to increase.The intraware silk screen is because structure and self character relation in addition, pressure drop is big, block easily, service life is short, the liquid load amount is restricted, make separator need usually maintenance and renewal part, troublesome maintenance is not suitable for high viscosity fluid and easy technology foamy.
Summary of the invention
For overcome existing gas-liquid separation equipment inefficiency, equipment investment is big, floor space is wide drawback, the present invention have utilized gravitational settling, centrifugation, baffling separation, isolated by filtration and mist to capture multiple separation principle, through particular design and on the basis of repeatedly practice research and development forming a kind of combined type separator.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of virgin gas filter, comprise the void tower separator, and be provided with gravitational settling district, eddy flow assembly, coalescent pack and filter core in the described void tower separator.The gravitational settling district provides enough spaces to allow drop grow up and settle down; Eddy flow assembly rotating diameter is very little, make gas under little gas flow and low gas velocity operating mode, still have stronger centrifugal force field, compare that volume-diminished is to 1/3 of conventional gravity separator with traditional centrifugal separation equipment, but efficient has reduced device height far above conventional gravity separator; Coalescent pack allows higher gas speed, and less pressure drop is provided, and has dwindled instrument size; Thereby filter core captures drop, mist and solid impurity by contact, interception, collision.
Preferred version of the present utility model is, a kind of virgin gas filter comprises the void tower separator, and described void tower separator is provided with filter core, coalescent pack, eddy flow assembly from top to bottom successively.It is characterized in that process gas is docile and obedient preface and enters inlet back earlier by the eddy flow assembly, is coalescent pack then, and at last by filter core to outlet; In a kind of combined type separator free column separator is arranged, described void tower separator is provided with outlet, filter core, coalescent pack, inlet tube and eddy flow assembly from top to bottom successively, and liquid outlet and sewage draining exit are positioned at the void tower separator lower end; What filter core adopted is metallic fiber sintered filter core, and the sintered metal fiber medium filtering accuracy is at 0.1～100 μ m. Described eddy flow assembly is that water conservancy diversion spiral eddy flow assembly or eddy flow plate or water conservancy diversion spiral eddy flow assembly and eddy flow Ban De Group close; Described inlet tube is the tangential entry pipe.
The beneficial effects of the utility model are: adopted gravitational settling, centrifugation, baffling separation, isolated by filtration and mist to capture multiple separation method, more common gas-liquid separator efficient has improved more than 3 times, raw material availability and product recovery rate have been improved, reduced power consumption, reduced the generation of accessory substance, simple in structure.
Adopted composite structuredly because this tests novel virgin gas filter, dwindled the pressure vessel volume, saved equipment investment and floor space; Compare with traditional filtration and separation techniques, small investment, resistance are little, few easy workout part, the cycle of operation are long.
Adopt the above liquid particles of this solid particle of testing separable 3～5 μ m of novel virgin gas filter and 10 μ m; Separator top adds the filter-type resolution element and then can the drop of 0.1～3 μ m effectively be separated, and that has stopped liquid substantially carries phenomenon again secretly.The automatic cleaning function of coalescent pack makes cured matter and solid particle be washed down, thereby avoids stopping up.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is further specified.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is a vertical view of the present utility model.
1. outlets among the figure, 2. filter core, 3. manhole, 4. coalescent pack, 5. tangential entry pipe, 6. the eddy flow assembly one, and 7. the eddy flow assembly two, 8. sewage draining exit, 9. liquid outlet.
The specific embodiment
The core of isolated by filtration is to utilize the characteristic of filter core to come liquid small in the divided gas flow material, solid impurity, because the existence of larger particles has increased the filter core load greatly, has increased the wash number of filter core, has reduced the service life of filter core.Therefore, equipment is designed to the combined filter of cyclone centrifugal separation, coalescent pack separation, three grades of one of filter element filtering, will obtains optimum efficiency and service life.
In a kind of combined type separator free column separator is arranged, described void tower separator is provided with outlet (1) from top to bottom successively, filter core (2), manhole (3), coalescent pack (4), tangential entry pipe (5), eddy flow assembly one (6), eddy flow assembly two (7), sewage draining exit (8), liquid outlet (9).During normal the operation, separated medium or process gas enter eddy flow assembly one (6) by first separation from inlet tube (5), down stream is separated for the third time to upper reaches coalescent pack (4) then, and is separated for the last time by filter core (2) at last by two (7) the back secondary separation of eddy flow assembly.
Process gas enters filter by filter tangential entry pipe (5), by eddy flow assembly between eddy flow assembly cylindrical shell and the equipment barrel one (6) and the thick part two (7) of eddy flow, eddy flow assembly one is the water conservancy diversion spiral, eddy flow assembly two is the eddy flow plate, realize gas-liquid, gas solid separation by gravity and centrifugal force, the solid, liquid particle of 80-90% is separated, and is discharged to device bottom by discharging tube.
Separate back gas and continue up by coalescent pack (4), the particle of 10-100 μ m is by coarse separation, and efficient can reach 90%.Gaseous mixture gas through coalescent pack (4) layer time can be evenly distributed at packing layer, and passing through of flow speed stability can be hit at filling surface during fine droplet process packing layer, forms liquid film, compiles, and along the groove of filling surface, flows out under the gravity effect.Small solid particle can collide continuously at filling surface when passing through packing layer, constantly changes direction, underspeeds, and a part is by the washing of the liquid film of filling surface, and a part is got off because of gravitational settling.So short and small packing layer is equivalent to a very high gravitational settling space.
Last gas is filtered by high-precision filter core (2) again, and impurity such as profit remaining in the gas, dust are tackled; Clean gas flows out by filter top outlet (1); The impurity that separates is discharged by the sewage draining exit (8) of equipment.
What filter core (2) adopted is metallic fiber sintered filter core, is to form by high temperature, pressure sintering in vacuum drying oven, and the sintered metal fiber medium filtering accuracy is in the special oleophobic hydrophobic treatment of 0.1～100 μ m surface of filter medium process.
