Description

Vynález se týká filtru na saze s prstencovým prostorem pro vznetové motory, který je opatŕen hoŕákem, opalujícím vrstvy sazí usazené na filtračních svíčkách, pŕičemž spaliny z motoru jsou vedený tangenciálním vstupem do prstencového prostoru, obklopujícího horák, ze kterého procházejí pŕes spalovací komoru do filtračního prostoru.BACKGROUND OF THE INVENTION The present invention relates to a soot filter with an annular space for compression ignition engines having a burner for tanning soot layers deposited on the filter candles, the flue gas from the engine being guided tangentially into the annular space surrounding the burner from which they pass through the combustion chamber into the filtration space. .

U filtru na saze je známé pŕivádét spaliny vznetového motoru tangenciálním vstupem do prstencového prostoru, který obklopuje horák a ze kterého spaliny proudí k filtračnímu prostoru. Spaliny, které krouží v prstoncovóm prostoru, naruáují pritom plyny pŕicházející vstupem, čímž vzniká podstatné vírení, které zvyšuje celkový prfltokový otvor filtru na saze.In the soot filter, it is known to supply the exhaust gas of a diesel engine through a tangential inlet into the annular space that surrounds the burner and from which the exhaust gas flows to the filter space. The flue gases, which circulate in the annular space, disturb the gases coming in through the inlet, thereby creating a substantial turbulence which increases the total flow opening of the soot filter.

Podstata_vynúlezuPodstata_vynúlezu

Vynález si klade za úkoL dosáhnout filtru na saze v úvodu uvedeného typu pokud možno co nejnižsího odporu proti proudéní a co nejvyášího tlumení hluku,SUMMARY OF THE INVENTION It is an object of the present invention to provide a soot filter of the type mentioned at the outset as low as possible to counter flow and to reduce noise as much as possible,

Vytčoný úkol. se ŕeáí filtrem podie vynálezu, jehož podstata spočíva v tom, že oblast prstencového prostoru, do které vstupuj! spaliny, je od oblasti prstencového prostoru, do které pŕicházejí spaliny po úplném prútoku prstencovým prostororu, oddelená stenou, laková stena, zejména vodiči plech, zabezpečuje, že vstúpení do prstencového prostoru pŕicházející proud spalín není vystavován žádnému zvírení a tak múže poraórné nerušené protékat prstoncovým prostorem, aby potom nejpozdéji u vodicího plechu opustil prstencový prostor a postoupil do filtračního prostoru. Tím se dpsahuje rovnomôrného proudéní pred, v a za prstencovým prostorem, čímž se podstatné sníží celkový prútokový odpor filtru na saze® Takový ma iý prútokový prostor celého systému pŕináší tu podstatnou výhodu, že se ukĺádá podstatné vétší množství sazí, protože múže být uložená tlustší vrstva sazí pred tím, než by tlak byl dostatečné velký pro zajiôténí prútoku filtrera na saze. Tím se muže uskutočňovať opalování sazí ve vetších časových interyalech a životnosť filtru na saze.se zvýši,A busy task. The filter according to the invention is characterized in that the region of the annular space into which it enters the air-purifying zone. The flue gas is separated from the area of the annular space into which the flue gases arrive after full flow through the annular space, separated by a wall, a lacquer wall, especially a guide plate, ensures that the incoming flue gas flow is not exposed to to leave the annular space at the latest at the guide plate and advance into the filter space. This provides for an even flow in front of and behind the annular space, thereby substantially reducing the total flow resistance of the soot filter. Such a small flow space of the entire system provides the significant advantage that a significant amount of soot is stored because a thicker layer of soot can be deposited. before the pressure is large enough to ensure the flow of the soot filter. As a result, soot tanning can be performed in larger interyals and the filter life on the soot will increase,

Filtr na saze podie vynálezu má optimálni vlastnosti z hlediska tlumení hluku. To je dáno tím, že prstencový prostor vytváŕí velký rovnomôrný uklidnovací prostor, prostŕednictvíni kterého se ve spolupráci s následnou expanzní komorou dosahuje vysokých hodnoť tlumení hluku. K tomu pŕispívá také na vstupní strane uspoŕádaný vodiči plech a rozdélování proudéní druhou prstencovou komorou, která je upravená mezi dvema válcovými dôrovanými plechy.The soot filter according to the invention has optimum noise damping properties. This is due to the fact that the annular space forms a large, even, calming space through which high noise attenuation values are achieved in cooperation with the subsequent expansion chamber. A guide plate arranged on the inlet side and a flow distribution through a second annular chamber, which is arranged between two cylindrical perforated plates, also contribute to this.

Další výhodná vytvorení vynálezu jsou uvedená v dalších patentových nárocích.Further advantageous embodiments of the invention are set forth in the other claims.

Filtr na saze uiá skríň 1_ s bočním, tangenciálné uspoŕádaným vstúpení 2 a s koaxiálne uspoŕádaným výstupem _3. Vstup 2 vede do prstencového prostoru 4, který souose obklopuje horák 5. Válcová dérovaná stóna 5b spalovací komory 5a je koaxiálne obklopená válcovou druhou dôrovanou stenou 5c a prstencový prostor 5U je mezi dvéma dérovanými stenami 5b, 5c otevŕený ve sméru k expanzní komore 4a.The soot filter comprises a housing 1 with a lateral, tangentially arranged inlet 2 and a coaxially arranged outlet 3. The inlet 2 leads to an annular space 4 which coaxially surrounds the burner 5. The cylindrical perforated wall 5b of the combustion chamber 5a is coaxially surrounded by a cylindrical second perforated wall 5c and the annular space 5U is open between two perforated walls 5b, 5c open towards the expansion chamber 4a.

Plamenné plyny, vystupující z horáku 5, jsou vychylovány kuželovitou vodiči destičkou 6, která je upravená v expanzní komore 4a. Odtud jsou plyny vedený do filtračního prostoru 2« ve kterém je upraven vétší počet filtračních svíček 8,'které jsou uspoŕúdány navzájom rovnobežné a jsou také rovnobéžné s osou skrine 1.The flame gases exiting the burner 5 are deflected by the conical conductor plate 6 which is provided in the expansion chamber 4a. From there, the gases are led to a filter space 2 ' in which a plurality of filter plugs 8 are arranged, which are arranged parallel to each other and also parallel to the axis of the housing 1.

Filtrační svíčky 8 jsou u znázorneného príkladu provedení osové filtry s keramickými näviny 9 na dérovaných filtračních kovových trubkách 1 0. Äovové trubky 10 jsou na tom konci, který je pŕivrácen k horáku 5 uzavŕeny a protilehlými konci vyústují do sbérného prostoru 11. který je obklopen tlumičem 12 hluku a který vede k výstupu 3.The filter plugs 8 in the embodiment shown are axial filters with ceramic studs 9 on the perforated filter metal tubes 10. 12 which results in output 3.

Spaliny vznétovéhó motoru vstupuj! do prstencového prostoru 4 prostŕednictvítn vstupu 2 a odtud jsou vedený pŕes spojovací komoru 5a do filtračního prostoru 2· 2de protékají filtračním prostoreia 7 a procházejí valcovými stenami 8a filtračných svíčok č), a potom proudí vnitŕkem filtraóních svíček b do sberného prostoru 11 a k výstupu ji. Pritom se saze, které jsou ve spalinách, usazují v keramických návinech 9 a na vnéjší strane v podobé vrstvy, která není na výkrese znázornená.Diesel engine combustion gases enter! into the annular space 4 through the inlet 2 and from there through the connecting chamber 5a to the filter space 2, 2de flow through the filter space 7 and pass through the cylindrical walls 8a of the filter candles 8, and then flow inside the filter candles b The carbon black present in the flue gas is deposited in the ceramic windings 9 and on the outside in a layer not shown in the drawing.

V prstencovém prostoru £ je tečno k valcové dérované stčnó spalovací koajory 4a upevnôn vodiči plech 13. Vodiči plech 13 oddôluje oblast 14 prstencového prostoru £, do která vstupují spaliny, od oblasti 15 prstencového prostoru 4, do které se dostávají spaliny po úplném prätoku prstencovým prostorem £. Pritom je vodiči plech 13 nastaven šikmo vzhledem k dopadajícímu proudční tak, že proud spalin je pŕiváden k filtračnímu prostoru £, prípadné k expanzní komore 4a.In the annular space 4, the guide plate 13 is fixed tangential to the cylindrical perforated side combustion chamber 4a. The guide plate 13 separates the area 14 of the annular space 4 into which the flue gas enters, from the area 15 of the annular space 4 into which the flue gas reaches the annular space. £. In this case, the guide plate 13 is adjusted obliquely with respect to the incoming flow so that the flue gas flow is fed to the filter chamber 4, possibly to the expansion chamber 4a.
