An exhaust pollutant monitoring and purification device

Abstract

The invention belongs to the technical field of diesel engine tail gas treatment devices, and discloses an exhaust pollutant monitoring and purification device, which includes a first pipeline, a first catalytic converter, a second pipeline, a second catalytic converter, a third pipeline, a process ECU, and an HMI devices and master devices. The present invention aims at the characteristics of the diesel engine thermal test bench, arranges the exhaust purification device on the exhaust branch pipe of each bench of the diesel engine laboratory, adopts the mode of centralized control and distributed implementation, and is flexible according to the actual workload of the laboratory. Control the working status of each group of exhaust purification devices, and reduce the cost of pollutant control on the premise of meeting the requirements of industrial pollutant discharge regulations.

Description

technical field [0001] The invention relates to the technical field of diesel engine tail gas treatment devices, in particular to an exhaust pollutant monitoring and purification device. Background technique [0002] The diesel engine test runs through the entire diesel engine R&D and production process. During the test period, the environmental pollution problems caused by the exhaust emissions of the diesel engine bench also arise. According to the requirements of relevant regulations, it is necessary to monitor the amount of pollutants in the flue through the bench after-treatment device. [0003] The diesel engine hot test bench has the following characteristics: [0004] 1. Multiple benches share one exhaust flue. According to the different usage rates of the benches, the exhaust volume in the flue and the concentration of pollutants vary widely; [0005] 2. According to different test conditions, the exhaust frequency in the flue is also different. If it is a durabil...

Problems solved by technology

[0010] The disadvantages of the existing exhaust gas treatment devices for vehicles are that the exhaust gas treatment capacity is relatively weak, the system back pressure is high, and it cannot meet the treatment requirements of the full-type diesel engine test on the bench, and it does not have the ability of human-computer interaction

The disadvantage of the existing exhaust flue tail gas treatment device is that the device is highly complex, suitable for treating continuous high-concentration and large-flow tail gas, and the cost of manufacturing, installation and use is too high

[0011] Therefore, according to the exhaust characteristics of the diesel engine test bench, the vehicle exhaust gas treatment device and the exhaust flue gas treatment device do not meet the application requirements, and new devices need to be developed to realize the exhaust pollutant monitoring and purification functions of the diesel engine test bench
