Abstract
The invention discloses a honeycomb carrier of a catalytic cleaner for tail gas clean-up. The honeycomb carrier comprises a shell (1), wherein a plurality of unit passages (2) are densely arranged in the shell and comprise outer annular plates (21) with parallelogram sections and inner annular plates (22) with parallelogram sections in the outer annular plates; the outer annular plates and the inner annular plates are enclosed into unit passages with sinuous sections; corresponding edges of the inner annular plates and the outer annular plates are parallel to one another; connecting plates (23) are arranged between corresponding corners of the outer annular plates and the inner annular plates; and annular passages enclosed by the outer annular plates and the inner annular plates are partitioned into four pore canals (3) with trapezoidal sections by the connecting plates. According to the honeycomb carrier of the catalytic cleaner for tail gas clean-up, the contact area of a coating agent and tail gas is greatly increased, the specific surface area is increased, the tail gas catalytic clean-up efficiency is increased, the structural strength is high, and the life is prolonged.
Description
Technical field
The present invention relates to the honeycomb substrate of a kind of tail gas clean-up catalytic cleaner.
Background technology
Environmental pollution especially atmosphere pollution has become the matter of utmost importance that perplexs human society harmonious development, and industrial waste gas, motor-vehicle tail-gas are the main sources of atmosphere pollution.At present, the major way that industrial waste gas and motor-vehicle tail-gas are administered is catalytic purification, at coating active component cellular carrier, will be catalytically converted into innocuous gas by the pernicious gas in honeycomb substrate duct.The key that honeycomb substrate is applied to tail gas catalytic purification is to make active component to disperse in its surface, obtains higher specific area, improves the catalytic efficiency of unit mass active component.In addition, honeycomb substrate in application process many places under vibrating state and face at a high speed, the continuous impact of high temperature gas flow, this just requires honeycomb substrate to have higher mechanical strength.The honeycomb support of prior art manufacture in fact all adopts square hole structure, does not possess the feature of alveolate texture, and specific area is low and structural strength is poor, and result of use is uneven.
Summary of the invention
Problem to be solved by this invention is to provide the honeycomb substrate of a kind of tail gas clean-up catalytic cleaner, and specific area is large, tail gas clean-up efficiency is high, structural strength is high.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: the honeycomb substrate of catalytic cleaner for a kind of tail gas clean-up, comprise housing, in described housing, gather and arranging some unit channels, described unit channel comprises that cross sectional shape is the outer ring plate of parallelogram and the inner ring plate that is located at outer ring plate middle section and is shaped as parallelogram, described outer ring plate and described inner ring plate surround the unit channel that cross sectional shape is " returning " font, the described inner ring plate limit corresponding with described outer ring plate is parallel to each other, described outer ring plate and inner ring plate are provided with connecting plate between corresponding angle, it is trapezoidal duct that the circular passage that described connecting plate surrounds outer ring plate and inner ring plate is divided into four cross sectional shapes.Greatly increase specific area, extended the time of tail gas stream through carrier, improved tail gas clean-up effect.
Improved, described unit channel evenly and be close to and be distributed in housing.Enclosure interior is divided into parallelogram duct and trapezoidal duct.
Improved, the center superposition of described outer ring plate and described inner ring plate.The structure in each trapezoidal duct is consistent.
Improved, the cross sectional shape of described outer ring plate and the cross sectional shape of described inner ring plate are rhombus.
Improved, the cross sectional shape of described outer ring plate and the cross sectional shape of described inner ring plate are rectangle.
Improved, the cross sectional shape of described outer ring plate and the cross sectional shape of described inner ring plate are square.The specific area in parallelogram duct and trapezoidal duct is maximized.
Improved, the cross sectional shape of described housing is that square or rectangular or hexagon are circular or oval.Beneficial effect:
Adopt after technique scheme, a kind of tail gas clean-up of this invention with the honeycomb substrate of catalytic cleaner greatly increased coating agent and tail gas contact area, improved specific area, improved tail gas catalytic purification efficiency, and structural strength is high, has extended the life-span.
Brief description of the drawings
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
Fig. 1 is the structural representation of one embodiment of the present invention;
Fig. 2 is the structural representation of unit channel in Fig. 1.
Detailed description of the invention
As depicted in figs. 1 and 2, the honeycomb substrate of catalytic cleaner for a kind of tail gas clean-up, comprise housing 1, in described housing, gather and arranging some unit channels 2, described unit channel comprises that cross sectional shape is the outer ring plate 21 of parallelogram and the inner ring plate 22 that is located at outer ring plate middle section and is shaped as parallelogram, described outer ring plate and described inner ring plate surround the unit channel that cross sectional shape is " returning " font, the described inner ring plate limit corresponding with described outer ring plate is parallel to each other, described outer ring plate and inner ring plate are provided with connecting plate 23 between corresponding angle, it is trapezoidal duct 3 that the circular passage that described connecting plate surrounds outer ring plate and inner ring plate is divided into four cross sectional shapes.Described unit channel evenly and be close to and be distributed in housing.
The center superposition of described outer ring plate and described inner ring plate.The cross sectional shape of described outer ring plate and the cross sectional shape of described inner ring plate are rhombus, or the cross sectional shape of described outer ring plate and the cross sectional shape of described inner ring plate are rectangle, as preferably, the cross sectional shape of described outer ring plate and the cross sectional shape of described inner ring plate are square.
The cross sectional shape of described housing is that square or rectangular or hexagon are circular or oval.
A kind of tail gas clean-up adopts pottery to make with the honeycomb substrate of catalytic cleaner, all fires straight forming and is connected and fixed by curing between described unit channel, between described unit channel and housing, between described outer ring plate and connecting plate and between described inner ring plate and connecting plate; Or a kind of tail gas clean-up adopts metal to make with the honeycomb substrate of catalytic cleaner, between described unit channel, between described unit channel and housing, between described outer ring plate and connecting plate and between described inner ring plate and connecting plate all by being welded to connect.
Except above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can make according to the present invention various changes and distortion, only otherwise depart from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
