Abstract
The utility model relates to a tail gas particle catcher and a filter core thereof. A shell of the catcher is internally provided with the filter core, the filter core is lengthways overlapped and coiled by a metal fiber plate and a corrugated plate with a wavelike cross section to be cylindrical, an axial air flow passageway is formed between the corrugated plate and the metal fiber plate, a plurality of first flow guide gaps and a plurality of flow guide concave grooves are arranged on the wave peak of the corrugated plate, and a plurality of second flow guide gaps and a plurality of flow guide convex grooves are arranged on the wave trough of the corrugated plate. The first glow guide gaps, the flow guide concave grooves, the second flow guide gaps and the guide convex grooves on the corrugated plate are used for guiding the tail gas, so that the time of the tail gas remaining in the catcher is greatly prolonged, a part of the tail gas is guided to pass through a metal fiber layer, and the particulate matter in the tail gas is baffled at one side surface of the metal fiber; and the other part of the tail gas is directly discharged. The utility model is very small in the exhaust pressure loss under the definite filter efficiency.
Description
Technical field
The utility model relates to the grain catcher of motor exhaust, and specifically a kind of tail gas grain catcher and filter core thereof belong to engine exhaust emission control gear technical field.
Background technique
No matter be diesel engine, petrol engine, or other gas internal-combustion engine, when work, can give off pollutant, comprise gas pollutant and particulate pollutant.The effect of grain catcher is that the particulate matter that will be comprised in the tail gas captures, thus make the tail gas that enters atmosphere cleaner and meet the country Abgasgesetz.
Existing tail gas grain catcher, its filter core generally have the powder metallurgy of filtering material, metal medium of porous ceramics medium and wire gaze etc.Though these filter cores are to the arresting efficiency height of particle, because captive particulate matter accumulates in the catcher, increase along with particulate matter in the catcher, the exhaust back pressure of motor can progressively rise, and to a certain degree rear engine oil consumption meeting increases, and efficient can reduce.Therefore, need clear up grain catcher according to the working condition of motor, adopt the method cleaning particulate matter of physics or chemistry to be called regeneration, the functional rehabilitation that makes catcher after the regeneration is to initial level.But the very difficult grasp of regeneration opportunity shifts to an earlier date or hysteresis easily, thereby influences the function of catcher.
Summary of the invention
The utility model provides a kind of tail gas grain catcher and filter core thereof at the problems referred to above, and this catcher and filter core thereof were both effective to the granule capturing in the tail gas, and is very little to the exhaust pressure loss again.
According to the technical solution of the utility model: a kind of filter core of tail gas grain catcher, it rolls into cylindrical by steel fiber plate and cross section corrugated sheet longitudinal overlap in wave shape, constitute axial air-flow path between described corrugated sheet and the described steel fiber plate, the crest of described corrugated sheet is provided with a plurality of first diversion gaps and diversion groove, and the trough of described corrugated sheet is provided with a plurality of second diversion gaps and water conservancy diversion tongue.
Described diversion groove and described water conservancy diversion tongue are obliquely installed to the outlet side by the inlet end of described air-flow path.
Described diversion groove and described water conservancy diversion tongue are axially staggered evenly to be provided with.
Described diversion groove and described water conservancy diversion tongue are one-body molded on described corrugated sheet.
A kind of tail gas grain catcher comprises the catcher housing, is provided with described filter core in the described catcher housing.
Described catcher housing is made of inlet end cone shell, circular cylindrical shell and outlet side cone shell, described inlet end cone shell is provided with suction port, described outlet side cone shell is provided with the air outlet, the inlet end of the air-flow path of described filter core is corresponding with described suction port, and the outlet side of described air-flow path is corresponding with described air outlet.
Technique effect of the present utility model is: filter core of the present utility model is made of steel fiber plate and corrugated sheet, first diversion gap on the corrugated sheet, diversion groove, second diversion gap and water conservancy diversion tongue are used for tail gas is led, the waiting time of tail gas in catcher prolonged greatly, part tail gas is conducted through metallic fibrous layer, and the particulate matter in the tail gas is blocked in a side of steel fiber; Another part tail gas is directly discharged, and the exhaust pressure loss that the utility model is caused under certain filter efficiency is very little.
