Abstract
The utility model relates to a wall flow honeycomb ceramic filter body for filtering gases. Parallel honeycomb pore channels are arranged in the shaft direction of the ceramic body. The pores of both ends of the adjacent honeycomb pore channels are alternately blocked. Micropores are evenly distributed on the honeycomb wall of the honeycomb pore channel. The honeycomb pore channel has 14-18 holes per centimeters square. The thickness of the honeycomb wall is 0.31-0.5 mm. The porosity of the micropore is greater than 35%. Polluted gases can be discharged through the micropores of the honeycomb wall of the honeycomb pore channel. Filtration efficiency can reach over 98%. The change of the size of the micropore can directly influence a filtering effect and collecting amount. Press resistant intensity can reach 1.4 kg per sq. cm. The utility model is an optimum product for filtering the polluted gases.
Description
The utility model relates to the design and fabrication technology to the filtering bodies of purifying vehicle exhaust and industrial fumes filtration.
At present, the tail gas of discharges such as various types of diesel locomotives, oil burning boiler, steamer, train is not handled and just is discharged in the atmosphere, and air pollution index is improved, and has a strong impact on the healthy of people.Especially the soot particle that diesel vehicle discharged, contain a lot of noxious materials, it is by the carbonaceous material of similar graphite form and condenses and adsorbed the materials such as ash of certain macromolecule organic, carbide, containing metal composition, is discharged in the atmosphere, can not disappear for a long time, harm is serious.
The purpose of this utility model provides a kind ofly catches the wall-flow honeycomb ceramic filter that filtration, purification is effective to harmful soot particle.
The purpose of this utility model is to realize like this, constitute by ceramic body and the hole that distributes above thereof, it is characterized in that: ceramic body is for axially to have many parallel honeycomb ducts, adjacent two ends, honeycomb duct to replace plug-hole, uniform micropore on the honeycomb wall in honeycomb duct.The honeycomb duct is 14～18 hole/square centimeters, honeycomb wall thickness 0.31～0.5mm, and the porosity of micropore is greater than 35%.
The utility model has the advantages that: rational in infrastructure, be easy to make, use and change conveniently, dusty gas just can emit by the micropore on the honeycomb wall of honeycomb duct, and filter efficiency can reach more than 98%, and the size that changes micropore then directly influences filter effect and amount of collected.Sintering temperature was more than or equal to 1500 ℃ when this filtering bodies was made, and compression strength reaches 1.4 kilograms/square centimeter, is the splendid product that dusty gas is filtered.
Below in conjunction with drawings and Examples the utility model is described.
Fig. 1 is the utility model longitudinal section.
Fig. 2 is the utility model sectional view.
Fig. 3 is the A enlarged drawing of Fig. 1.
Embodiment 1
This filtering bodies as shown in Figure 1 to Figure 3, constitute by ceramic body and the hole that distributes above thereof, ceramic body 1 is a cylinder, many parallel honeycomb ducts 2 are axially arranged, and cross section, honeycomb duct is a square, and adjacent two ends, honeycomb duct replace plug-hole, uniform micropore 3 on the honeycomb wall in honeycomb duct, the honeycomb duct is 15 hole/square centimeters, and honeycomb wall thickness is 0.35mm, and the porosity of micropore is 38%.Through experiment, filter efficiency reaches more than 95%.Prepare raw material by ceramic process, through old, refining, extrusion modling, drying, form by a firing, plug-hole, form by a firing again, in raw material, add chemical compound, in the process of forming by a firing, form micropore.
This filtering bodies, constitute by ceramic body and the hole that distributes above thereof, ceramic body 1 is a cuboid, many parallel honeycomb ducts 2 are axially arranged, cross section, honeycomb duct is a square, adjacent two ends, honeycomb duct replace plug-hole, has aperture in the plug-hole in ceramic body one end honeycomb duct less than 0.1mm, the aperture distributive law is less than 20%, uniform micropore 3 on the honeycomb wall in honeycomb duct, and the honeycomb duct is 16 hole/square centimeters, honeycomb wall thickness is 0.31mm, the micropore porosity is 40%, and through experiment, filter efficiency reaches more than 96%.
