Embodiment Construction

[0034] see Figure 1-5 , the present invention relates to a trapezoidal exhaust gas filter, which includes a filter box 1, a filter screen 2 and a ceramic honeycomb carrier 3, the left end of the filter box 1 is an exhaust gas inlet 4, and the right end is an exhaust gas outlet 5, the filter screen 2 and ceramic honeycomb The carrier 3 is arranged in the filter box 1, and the filter screen 2 is close to the exhaust gas inlet 4. The filter box 1 includes a first arc edge 1.1, a second arc edge 1.2, a first hypotenuse 1.3 and a second hypotenuse 1.4, The first arc side 1.1, the second hypotenuse 1.4, the second arc side 1.2 and the first hypotenuse 1.3 are connected end to end in sequence, and the joints adopt rounded transitions. The shape of the ceramic honeycomb carrier 3 is similar to that of the filter box 1 Correspondingly, the ceramic honeycomb carrier 3 is densely covered with air holes 3.1 along the axial direction, one end of the air holes 3.1 is an opening 3.6, and th...

Abstract

The invention relates to a trapezoidal tail gas filter. The trapezoidal tail gas filter comprises a filter box (1); a filter net (2) and a ceramic honeycomb carrier (3) are arranged in the filter box (1); and a spraying head (8) is arranged at the front end of the filter box (1). The trapezoidal tail gas filter firstly uses sodium carbonate water mist for eliminating acid components in tail gas, then reacts the tail gas with main components of CO, HC and NOx as CO2, H2O, N2 and O2 under two grades of filtration by the filter net and the ceramic honeycomb carrier, can effectively filter black smoke particles in waste gas through micro holes in separation walls, can burn the black smoke particles under the effect of catalyst coating layers, and further improves the tail gas purifying effect.

Description

technical field [0001] The invention relates to a trapezoidal exhaust gas filter, which is used for purifying automobile exhaust gas. It belongs to the technical field of automobile equipment. Background technique [0002] At present, ordinary automobile exhaust filters use catalysts to interact with NO and NO in automobile exhaust. 2 react with CO to form CO 2 and N 2 These two kinds of non-polluting gases, but the cars equipped with diesel engines, because the exhaust gas of diesel engines contains black smoke particles, the existing exhaust filter can not effectively filter the black smoke particles, which will cause environmental pollution; the acidity of the existing exhaust gas The further elimination of components is the new demand of people for exhaust gas treatment and urban environmental protection. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned deficiency, provides a kind of trapezoidal tail gas filter, ...
