Problems solved by technology

[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 a new demand for exhaust gas treatment and urban environmental protection

Embodiment Construction

[0031] see Figure 1-5 , the present invention relates to a cylindrical exhaust gas filter, which includes a filter box 1, a filter screen 2, a first ceramic honeycomb carrier 3 and a second ceramic honeycomb carrier 7, 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, the first ceramic honeycomb carrier 3 and the second ceramic honeycomb carrier 7 are arranged in the filter box 1, the filter screen 2 is close to the exhaust gas inlet 4, the filter box 1 is cylindrical, and the first The ceramic honeycomb carrier 3 and the second honeycomb carrier 7 have the same structure, and the shape corresponds to the filter box 1. The first 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 the other end is set There is a blocking surface 3.2, the blocking surface 3.2 and the opening 3.6 are arranged at intervals, the t...

Abstract

The invention relates to a cylindrical tail gas filter. The cylindrical tail gas filter comprises a filter box (1); a filter net (2), a first ceramic honeycomb carrier (3) and a second ceramic honeycomb carrier (7) are arranged in the filter box (1); and a spraying head (9) is arranged at the front end of the filter box (1). The cylindrical 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, the first ceramic honeycomb carrier and the second 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 cylindrical tail gas filter, which is used for purifying automobile tail 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 cylindrical tail gas filter, this t...
