Abstract
The utility model relates to a no amortization tubular muffler. It includes rose box (1), be provided with oxidizing catalytic converter (2), particulate filter (3) and hush pipe (5) in rose box (1), oxidizing catalytic converter (2) set up exhaust intake department, and particulate filter (3) set up in air exit department, and oxidizing catalytic converter (2) link to each other with particulate filter (3), and the export of particulate filter (3) links to each other with blast pipe (4), be provided with twice baffle (5) on particulate filter (3), be provided with on baffle (5) and cross the filtration pore with particulate filter's (3) filter core corresponds. The utility model relates to a no amortization tubular muffler does not use the hush pipe noise muting that just can effectively disappear to can filter the particulate matter in the tail gas.
Description
Technical field
The utility model is related to one kind without muffler tube type muffler.Belong to tail gas from diesel electric generator filtration art.
Background technology
For the muffler of the elimination of tail gas from diesel electric generator noise, due to higher containing PM values in tail gas, i.e. tail gas
In have after black particle, therefore long-time use, muffler inwall can adhere to a large amount of particulate matters, produce very big multiplication of voltage, such as
This can cause the noise cancellation effect of muffler to reduce, and affect vent gas treatment.
The content of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, there is provided one kind is not used and disappeared without muffler tube type muffler
Sound tube just can effectively abate the noise, and can filter the particulate matter in tail gas.
What the purpose of this utility model was realized in：
One kind is characterized in without muffler tube type muffler：It is described to include Rose Box, the filtration without muffler tube type muffler
Oxidation catalytic converter, particulate filter and hush pipe are provided with case, oxidation catalytic converter is arranged at exhaust gas intake port, particle
Filter is arranged at air exit, and oxidation catalytic converter is connected with particulate filter, outlet and the exhaust of particulate filter
Pipe is connected, and twice dividing plate is provided with the particulate filter, and mistake corresponding with the filter core of particulate filter is provided with dividing plate
Filter opening.
Compared with prior art, the beneficial effects of the utility model are：
The utility model is a kind of without muffler tube type muffler, and the tail gas that diesel generating set is discharged passes sequentially through oxidation catalysis
Converter and particulate filter are filtered, most after Jing blast pipes discharge, because the filter core of particulate filter has the property of honeycomb porous
Matter, coordinates twice dividing plate, therefore can reach the noise reduction of hush pipe, at the same the utility model can also filter out in exhaust
Grain thing.

Fig. 2 is the sectional view of Fig. 1.
In figure：
Rose Box 1,
Oxidation catalytic converter 2,
Particulate filter 3,
Blast pipe 4,
Dividing plate 5.
Specific embodiment
Referring to Fig. 1-2, the utility model is related to one kind without muffler tube type muffler, and it includes Rose Box 1, the Rose Box
Oxidation catalytic converter 2, particulate filter 3 and hush pipe 5 are provided with 1, oxidation catalytic converter 2 is arranged at exhaust gas intake port,
Particulate filter 3 is arranged at air exit, oxidation catalytic converter 2 is connected with particulate filter 3, and particulate filter 3 goes out
Mouth is connected with blast pipe 4, and twice dividing plate 5 is provided with the particulate filter 3, is provided with dividing plate 5 and particulate filter 3
The corresponding filter bores of filter core.
Oxidation catalytic converter 2, the application is referred to as DOC, and it is using noble metals such as platinum (Pt), palladiums (Pd) as catalysis
Agent, the main content for reducing the SOF in Particulate Emission is so as to reducing the discharge of PM.Can effectively reduce simultaneously HC in exhaust and
CO。
Particulate filter 3, the application is referred to as DPF, and DPF is to reduce particulate matter in exhaust（PM）The dress for discharging pollutants
Put.
Operation principle：
The tail gas that diesel generating set is discharged passes sequentially through oxidation catalytic converter 2 and particulate filter 3 is filtered, most after Jing
Blast pipe 4 is discharged, and because the filter core of particulate filter 3 has the property of honeycomb porous, coordinates twice dividing plate 5, therefore can be reached
The noise reduction of hush pipe, while the utility model can also filter out the particulate matter in exhaust.
