Further, ceramic filter comprises expanded metal, and expanded metal outer wall wraps up some layers of ceramic fibre.The ceramic filter adopting the mode of ceramic fibre parcel expanded metal to prepare, is convenient to change ceramic fibre on the one hand, avoids ceramic fibre to grow the ceramic hole blocking caused service time, improves the convenience used; The number of plies of ceramic fibre parcel can be decided on the other hand according to the exhaust-gas treatment amount of reality and processing speed, make rational use of resources.
Further, clip is provided with the flexure strip coordinated with guide channel.Flexure strip has certain cushioning effect, avoids rigidity effect when clip directly contacts with fixed leg, is conducive to clip and fixes and protect fixed leg.
Further, the internal diameter of waste gas inlet pipe and purification chamber link is the trend increased gradually at airflow direction.Can play cushioning effect, the exhaust gas pressure entering into waste gas inlet pipe is reduced gradually, and the waste gas avoiding air pressure too high directly acts on ceramic filter, and then produces damage to ceramic filter.
Further, screen pack is provided with in waste gas inlet pipe.The setting of screen pack tentatively can be filtered waste gas, is tackled by larger impurity, affects the filter effect of ceramic filter in the purification chamber avoiding larger impurity to carry out.
Further, poly-petticoat pipe is funnel structure, and one end that funnel structure internal diameter is less is connected with waste gas inlet pipe.Described funnel structure specifically refers to that the interior input without leave of poly-petticoat pipe reduces gradually to output, and what arranged by the internal diameter of poly-petticoat pipe output is comparatively large, is conducive to the absorption to waste gas, improves the absorption efficiency to waste gas.
To sum up, the invention has the beneficial effects as follows:
1, the present invention by arranging guide channel in purification chamber, the beginning of guide channel is provided with clip, the fixed leg arranged by its end for the ceramic filter of filtering exhaust and guide channel, clip coordinate the installation and removal realizing ceramic filter, simply easy to operate.
2, the present invention by being provided with multiple ceramic filter in purification chamber, and adjacent two ceramic filter set of times have gap, realize multiple filtration on the one hand, improve filter effect, on the other hand, gap has certain cushioning effect, enters lower one deck ceramic filter again and filters, improve filter effect after waste gas is cushioned after last layer ceramic filter in gap.
3, the present invention is by adopting the ceramic filter prepared of mode of ceramic fibre parcel expanded metal, is convenient on the one hand change ceramic fibre, avoids ceramic fibre to grow the ceramic hole blocking caused service time, improves the convenience used; The number of plies of ceramic fibre parcel can be decided on the other hand according to the exhaust-gas treatment amount of reality and processing speed, make rational use of resources.
