Abstract
Abstract The invention relates to a method and an apparatus for purifying gaseous fluids by separating the media such as oils present therein and contaminant particles present therein. To permit on the one hand problem-free cleaning of the separator area (14, 16, 18, 20) and on the other hand an increase in the separating degree, it is proposed that the gaseous fluid to be purified is cooled and/or that a gas or fluid is sprayed into the fluid before it passes through the separator area (14, 16, 18, 20).

A ~orresponding apparatus is described in EP 0 306 807 Bl.
In this appa~atus, the possib~lity of simple cleaning o~
the separator areas or the elements forming these is given when the apparatus is easily accessible. This allow~ a high-pressur~ oleaning device to be used for spraying p~rl~ying fluid onto the separator areas. The fact that the profile elements are easily removable means that the pro~ile el2ments not accessible from the outside can also be cleaned witho~t difficulty. It is however neGessa~y to interrupt thé waste air f lo~ during this operation.
Consequently, the ventila~ion facility incorporating the apparatus must be taken out of service.

Cleaning can however ca~se pro~lems i~ the apparatus itself should p~ove no~ to be easily accessible. Since the only pu~ifying fluids that can be used are those that can be di~pensed b-~ a high-pressure cleaning device, while the separated fluids such as oil mists have to be treated, care :
must be taken that the purifying fluid itself does not get into the collecting vessel holding the separated fluids.
One of the o~jects un~erl~ing the present inventio~ is to develop a ~ethod ~nd an appa~tu~ of the type de~ribed above such that problem-f~ee cleaning of the profile elements can take place reg~rdless of where the apparatus is installed. Howe~er, a further object of the present invention is to ens~re by simple measures that treat~ent o$
the separated fluids U~ing the purifying fluid it~elf is not impaired. In addition~ hould be possi~le to perform the purification operation without having to take the ventiiation facility incorporating the apparat~s out of service, 1.e. the separa~or must remain ln operation during pu~ification. In particular, however, an increase in the ~ep~rating degree shall be achieved, possibly with simultaneous cleaning off of the se~aration sur~ace.
According to the ~ethod, ~he problem is ~olved 6ubstantially in that the g~seous fluid to be purified i5 cooled before pas~ing through the separator are~ and/or fluid is sprayed in~o the fluid. The fluid is cooled here using ga~ or air to a temper~ture lo~er ~han that of the fluid.
~he measures in accordance with the invention result in virtually a nucleation of the particles to be separated in the gas f low through the separator area as a result of the spraying of cooling ai~ or fluid. As a result, large quantitie~ of liquid media are ~eparated at the profile ele~ent8 the~selves~ WhiCh in turn gener~eS a cleaning effect. ~hi~ is parti~ularly the case when fluid is sprayed into the gas to be purified, with the sprayin~
direction for thiS f~id ~eing op~osite to that of the fluid to be purified.

Th~ separator areas (14), (16), (18) and (20) comprise fir~t and second pro~ile sec~ions heing open in cross-section and trough-shaped a~d arranged in rows, where preferab~y the ~ree longitudinal edges of the borders of the first profile ~ections overlap t~e free longitudinal edges of the korders of the 6econd pro~ile sections. In addition, projections starting in the c~est area of the inner surfaces and extending in ~he di~ectian of the profile section openings and along their longitudinal a~es c~n b~ provided, whereby on the one hand the additional chambers affecting the fluid flow speed are formed and on the other hand fixtures are provided for holders to mo~nt th~ i~divi~ual profile sections detachably, but in exact pOSition.
~n other words, the profile sections arranged in rows and for~ing the separator area~ (14), (16), (18) ~nd (20) have a ~tr~cture as shown in, for examp}e, EP 0 206 204 B1 and in particular Figs. 1 and 2 thereo~. Regardless of thi~
special embodiment, EP 0 206 204 Bl represents - as do EP 0 306 807 ~l or EP 0 280 160 A1 - a supplementary disclosure to the present description.
To ensure th~t the separator areas (14), ~16), (18) and (20~ cannot be flowed round, i.e. bypassed, the interio~
sp~ce (40) surrounded by the ~eparator areas (14), (16), (18) and (20) is covered by an in~low element such as an inflow cone (42), by which the fluids to ~e purified are first guided along the inner ~Jalls (48) of the housing (12) and then flow through the geparator areas (14), (16), (læ) and (2~) for~ed by the profile se~tions. ~he purified fluids th~n pass into the interior (40) and are finally dispensed from the housing (12) via the outlet connector (~4).

The profile sections a~e fastened in moun~ing parts such as f~a~es, not shown in detail and ~orming the outer limit of the separator areas (14), (16), (18) and (20). The adjacent edges then practically form a collecting pipe (50) which collects media ~uch as oil separated in the separator areas and flowing due to gravity to the collec~ing pipe (50), and then passs~ them to an outlet pipe, not shown, ~hich in turn ~lows into a oollecting vessel. ~he fluids collected in the ~ollecting vessel can then be p~rified, thereby permitting a ~ajor reduction i~ the amount of substances for disposal.
.~ , ~he ~parator areas (14~ 6), (18) and (20) are connected by their mounting parts 6uch as pro~ile strips - not shown in detail - for mounting the holders for the profile sections to a back-up tube (52) runni~g coaxially to the longitudinal axi~ (38) of the housing (12), said back-up tube in lts turn being supported rotatably by tube ele~e~ts (54), (56), (58) and (60) ~nd centra~ly on the housing inner walle, in the central area of the housing surface6.
To permi~ cleaning of the pro~ile sections forming the separator ~reas (14), (16), (18) and (20), wit~out necessitating either an interr~p~ion of operation or t~e removal or opening of an inspection cover provided, and withou~ the ~eed to u~e a special high-pressure cleaning device, it is provided in accordance wi~h the invention tha~ al~ng the corners (62), 164), (66) and (68) of the housing (12~ pipes (70) and (72) are provided ~rom whiGh nozzles (74), (76), (78), (80), (82) and (~4) start, through which the purifying ~luids are dispensed onto the ~eparato~ area6 (14), (16), (18) and (20).
The purifying fluids are ~edia separated by the separator ar~a6 (14)j (16) (18) and (20), ~t in purified form. Thi6 has the advantage that the purifying media together with the separated media ca~ be jointly passed to the col~ecting ve~sel via collecting pipes, and ~hen u~dergo treatment and purificatio~.

This has the advantage not only that separation of purifying fluid and separa~ed ~edia is not necessary, but also that cleaning of the separator areas can t~ke place even during operation of the apparatus in accordance wit~
the invention. To increase the efficiency, the purifying fluid G~m be heated beforehand.
It is of course also possible to provide only one pipe with cleaning nozzles inside the housing (12), with the separator ~re~s ( 14), (l~), ( 18) and (20) then having to pass theEie no221e3 successively. In this case, however, it would be neces~ary for the element ~or~ing the separator areas ~14), (16), (18) and (20) to be rotatably mounted. If clean1ng nozzles are provided along each corner o~ the h~usi~g (12), however, a rotatable mounting is not necessary.
~o permit nore efficient cleanin~, the separator areas ~14), (16), (18) and (20) should, in accordance with the illustration in Fig. 2, be aligned in relation to the corners (62), (64), (66), (68~ and hence to ~he nozzles (74), (76), (78) and (80), meaning that normal lines gtart1ng from the separ~tor areas bisect ~he corners (62), (64), t66~ ~nd (68).
Fig. 3 5hows a preferred embodiment of a separa~or (88) provided in a waste air duct (~fi) in a design corresponding to the apparatus according to ~igs. 1 and 2.
~he ~luid sep~ated by the separator (88) is passed via a collecting pipe provided in the bottom area of the housing ~86) holding the separator ( 88) to a collecting ves&el (~0) from which the fluid can be drawn off or drained off in the usual ~anner for treatment or dispo~al ~e~pectively.

Separated ~luid can now be s~rayed through ~he fllter (9~) into the gas to be pu~ified, if necessary af~er passin~
throu~h a ~ilter (~8) in a counte~flow.

Fig. 4 shows a fur~her embodi~ent of a sep~rator array (102) that co~prises several separator areas (104~, (106) and (108) arran~ed one behind the other. The separator areas (104), (106) and (108) are designed as described in the ~oregoing. Regardless of this, the separator ~rray (102) corresponds in its design to the separator apparatus described in EP 0 280 160, and accordingly comprises an agglomerator ~110) for separating in particular ~i~ro-particles too.
To clean or moi~ten the ag~lomerato~ (110), so that it cannot dry out, a spraying device (112) is provided that is connec~Qd via a pipe (114) to the collecting vessel (90).
By the arrangemen~ in accordance with the invention, ~he a~glo~erator (110) is sprayed with the medium that is separQted at the separator areas ~104), (106) and (108).
This again has the advantage that in spite of moistening ~here is no additional fluid to be disposed of.
Fig. 5 ~hows a further variant of a ~eparator in which a separYtor are~ (118) is provided in a housing (1~8).
Th~ separator areas (14), (16), (18) and (20) comprise fir~t and second pro~ile sec~ions heing open in cross-section and trough-shaped a~d arranged in rows, where preferab~y the ~ree longitudinal edges of the borders of the first profile ~ections overlap t~e free longitudinal edges of the korders of the 6econd pro~ile sections. In addition, projections starting in the c~est area of the inner surfaces and extending in ~he di~ectian of the profile section openings and along their longitudinal a~es c~n b~ provided, whereby on the one hand the additional chambers affecting the fluid flow speed are formed and on the other hand fixtures are provided for holders to mo~nt th~ i~divi~ual profile sections detachably, but in exact pOSition.
~n other words, the profile sections arranged in rows and for~ing the separator area~ (14), (16), (18) ~nd (20) have a ~tr~cture as shown in, for examp}e, EP 0 206 204 B1 and in particular Figs. 1 and 2 thereo~. Regardless of thi~
special embodiment, EP 0 206 204 Bl represents - as do EP 0 306 807 ~l or EP 0 280 160 A1 - a supplementary disclosure to the present description.
To ensure th~t the separator areas (14), ~16), (18) and (20~ cannot be flowed round, i.e. bypassed, the interio~
sp~ce (40) surrounded by the ~eparator areas (14), (16), (18) and (20) is covered by an in~low element such as an inflow cone (42), by which the fluids to ~e purified are first guided along the inner ~Jalls (48) of the housing (12) and then flow through the geparator areas (14), (16), (læ) and (2~) for~ed by the profile se~tions. ~he purified fluids th~n pass into the interior (40) and are finally dispensed from the housing (12) via the outlet connector (~4).

The profile sections a~e fastened in moun~ing parts such as f~a~es, not shown in detail and ~orming the outer limit of the separator areas (14), (16), (18) and (20). The adjacent edges then practically form a collecting pipe (50) which collects media ~uch as oil separated in the separator areas and flowing due to gravity to the collec~ing pipe (50), and then passs~ them to an outlet pipe, not shown, ~hich in turn ~lows into a oollecting vessel. ~he fluids collected in the ~ollecting vessel can then be p~rified, thereby permitting a ~ajor reduction i~ the amount of substances for disposal.
.~ , ~he ~parator areas (14~ 6), (18) and (20) are connected by their mounting parts 6uch as pro~ile strips - not shown in detail - for mounting the holders for the profile sections to a back-up tube (52) runni~g coaxially to the longitudinal axi~ (38) of the housing (12), said back-up tube in lts turn being supported rotatably by tube ele~e~ts (54), (56), (58) and (60) ~nd centra~ly on the housing inner walle, in the central area of the housing surface6.
To permi~ cleaning of the pro~ile sections forming the separator ~reas (14), (16), (18) and (20), wit~out necessitating either an interr~p~ion of operation or t~e removal or opening of an inspection cover provided, and withou~ the ~eed to u~e a special high-pressure cleaning device, it is provided in accordance wi~h the invention tha~ al~ng the corners (62), 164), (66) and (68) of the housing (12~ pipes (70) and (72) are provided ~rom whiGh nozzles (74), (76), (78), (80), (82) and (~4) start, through which the purifying ~luids are dispensed onto the ~eparato~ area6 (14), (16), (18) and (20).
The purifying fluids are ~edia separated by the separator ar~a6 (14)j (16) (18) and (20), ~t in purified form. Thi6 has the advantage that the purifying media together with the separated media ca~ be jointly passed to the col~ecting ve~sel via collecting pipes, and ~hen u~dergo treatment and purificatio~.

This has the advantage not only that separation of purifying fluid and separa~ed ~edia is not necessary, but also that cleaning of the separator areas can t~ke place even during operation of the apparatus in accordance wit~
the invention. To increase the efficiency, the purifying fluid G~m be heated beforehand.
It is of course also possible to provide only one pipe with cleaning nozzles inside the housing (12), with the separator ~re~s ( 14), (l~), ( 18) and (20) then having to pass theEie no221e3 successively. In this case, however, it would be neces~ary for the element ~or~ing the separator areas ~14), (16), (18) and (20) to be rotatably mounted. If clean1ng nozzles are provided along each corner o~ the h~usi~g (12), however, a rotatable mounting is not necessary.
~o permit nore efficient cleanin~, the separator areas ~14), (16), (18) and (20) should, in accordance with the illustration in Fig. 2, be aligned in relation to the corners (62), (64), (66), (68~ and hence to ~he nozzles (74), (76), (78) and (80), meaning that normal lines gtart1ng from the separ~tor areas bisect ~he corners (62), (64), t66~ ~nd (68).
Fig. 3 5hows a preferred embodiment of a separa~or (88) provided in a waste air duct (~fi) in a design corresponding to the apparatus according to ~igs. 1 and 2.
~he ~luid sep~ated by the separator (88) is passed via a collecting pipe provided in the bottom area of the housing ~86) holding the separator ( 88) to a collecting ves&el (~0) from which the fluid can be drawn off or drained off in the usual ~anner for treatment or dispo~al ~e~pectively.
