Vehicle exhaust catalytic purifying device

Abstract

The invention discloses a vehicle exhaust catalytic purifying device including a purifying drum. An exhaust pipe penetrates through the left part of the upper end in the purifying drum, a noise reduction device is fixedly connected with the upper end of the exhaust pipe, a first filter net and a reduction catalyst core are fixedly arranged in the purifying drum separately, a cleaning device is fixedly arranged at the upper end of the purifying drum, a cycling pipe is fixedly connected with the upper end of the cleaning device, a collection device is fixedly connected with the lower end of thecycling pipe, and two oxidation drums are fixedly connected with the right end of the purifying drum. According to the vehicle exhaust catalytic purifying device, a catalyst layer of a spiral structure and a groove are arranged to prolong the responding time of a catalyst and exhaust and meanwhile enlarge the contact area to improve the purifying effect, and a noise reduction sponge and a ring-shaped ventilation pipe can achieve noise reduction of exhaust so that the service life of the device is prolonged. In addition, the cleaning device can guarantee that the exhaust purifying work can carry out stably and efficiently, and a collection groove and a second filter net can be cleaned regularly so that the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust purification, in particular to a catalytic purification device for automobile exhaust. Background technique [0002] At present, with the advancement of automobile manufacturing technology, the number of automobiles is increasing every year. The impact of automobile exhaust has exceeded the benefits of convenience and speed. Automobile exhaust contains hundreds of different compounds. The substances include solid suspended particles, carbon monoxide and nitrogen oxides. The damage of automobile exhaust to the earth environment and people's health is huge, so the exhaust gas needs to be purified, and the existing catalytic exhaust equipment often has the following defects in the purification process: 1. The current automobile exhaust purifiers are harmful to pollution The conversion efficiency of the gas is not high, so that the purification effect is not good, and the emission requirem...

Problems solved by technology

The damage of automobile exhaust to the earth environment and people's health is huge, so the exhaust gas needs to be purified, and the existing catalytic exhaust equipment often has the following defects in the purification process: 1. The current automobile exhaust purifiers are harmful to pollution The conversion efficiency of the gas is not high, so that the purification effect is not good, and the emission requirements cannot be met; 2. During the catalytic purification process of the existing automobile exhaust, because the exhaust gas flow hits the automobile exhaust catalytic purification device in large quantities, a large amount of noise is generated, thereby improving the catalytic performance. The service life of the purification device; 3. The large amount of dust and macromolecular particles carried in the exhaust gas during the treatment process of the existing exhaust gas cannot be effectively treated, and it is easy to accumulate inside the purification device, causing blockage of the catalytic purification device and affecting the smooth purification of the exhaust gas 4. The dust and macromolecular substances accumulated on the purification device are not convenient for regular cleaning and maintenance, which brings trouble to the maintenance work of maintenance personnel and increases maintenance costs
