Abstract
The utility model relates to an exhaust discharge purifying device, which comprises a main shell, an outer shell connected with the main shell, a metal positioning sheet, and an axial corrugated sheet, wherein the axial corrugated sheet is the continuous wave-shaped corrugated sheet, grooves are arranged on the positioning sheet and parallel with each other and has certain space that is integral a plurality of of the wave length of the axial corrugated sheet, the wave crest of the axial corrugated sheet corresponding to the grooves are embedded with the grooves to form a board, the board is winded into a core matching with the inner part of the outer shell, an insulating layer is arranged between the main shell and the outer shell, and a vent groove is arranged on the outer shell. Comparing to the prior art, the utility model has the advantages of reasonable structure, good shock resistance, good thermal conductivity, low volume under the same efficiency, improved adhesion of catalyst, and improved catalytic purification effect to harmful gas.
Description
Technical field:
The utility model relates to a kind of toxic emission purifier, particularly a kind of motor vehicle exhaust emission purifier.
Background technology:
In the prior art, motor-vehicle tail-gas purifying device adopts potter's clay core body usually, and its strength ratio is relatively poor, is vibrated easily in the process of moving and breakage, loses purification function.In addition, be subjected to the restriction of ceramic product processing technology, the filtering holes quantity of unit are is quite limited, can only reach 400 holes, square inch at present, and side purifies area and is subjected to certain limitation.This series products thermal conductance is low simultaneously, the thermal capacity height, and the clarifier volume under equal efficient is bigger.
Summary of the invention:
Technical problem to be solved in the utility model is to overcome above shortcomings in the prior art, and a kind of simple for structure, toxic emission purifier that efficient is high is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this toxic emission purifier, comprise main casing, shell, main casing is connected with shell, its architectural feature is also to be provided with the location-plate and the axial wave card of metal, the axial wave card is a continuous wave shape wave corrugated plating, location-plate is provided with groove, groove is parallel to each other and mutually across a certain distance, its spacing is the integral multiple of axial wave card wave length, crest that the axial wave card is corresponding with groove and recess-mounted constitute plate body, and this plate body is wound into the core body that is complementary with internal diameter of outer cover, be provided with heat-insulation layer between main casing and the shell, shell is provided with air channel.
The spacing of groove described in the utility model is the twice of corrugated plating wave length.
Core body described in the utility model is a cylinder.
Core body described in the utility model comprises two core bodys.
Main casing described in the utility model is provided with adpting flange and tube connector, and tube connector is connected with adpting flange.
Main casing described in the utility model, shell adopt metal to make, and main casing welds with the employing that is connected between the shell.
The utility model compared with prior art has the following advantages and effect: reasonable in design, and shock resistance is strong, and thermal conductance is good, and equal efficient lower volume is little, has improved the adhesive force of catalyst, has improved the catalyticing purifying effect to pernicious gas.
