Abstract

The application of the invention discloses a preheating type automobile exhaust purifier. According to the scheme, the preheating type automobile exhaust purifier comprises a purifying chamber, wherein the left end of the purifying chamber is communicated with an air inlet pipe, the right end of the purifying chamber is connected with a vent pipe, a heating layer is arranged in the middle inside the purifying chamber, the heating layer divides the purifying chamber into a left part and a right part, a filtering layer is arranged in each of the left part and the right part of the purifying chamber, foamed ceramics is filled into the filtering layer, a temperature sensor is arranged between the filtering layer in the left part of the purifying chamber and the heating layer, the temperature sensor is connected with a controller, and the controller is connected with the heating layer. The application of the invention aims at providing a preheating type automobile exhaust purifier, so that the exhaust can absorb heat produced by oxidoreduction and consumption of a heater on energy can be reduced.

Description

technical field [0001] The invention relates to a preheating type automobile tail gas purifier. Background technique [0002] Vehicle exhaust pollution has become the main source of air pollution, and fuel vehicles will remain the mainstream products of the automotive industry for a period of time to come. In recent years, domestic and foreign attach great importance to the research work of automobile exhaust purification technology. The high-strength, high-temperature oxidation-resistant conductive foam ceramic material in the prior art has been applied in the purification device. However, due to its poor low temperature activity and high ignition temperature, the exhaust gas purification effect is poor when the car is cold started. [0003] In view of the above problems, the patent document with the publication number CN201461044U discloses a motor vehicle exhaust gas purifier. The device adopts far-infrared quartz tube, which is installed in the center of the shell, and...
