Multi-component waste gas online monitor

Abstract

The invention discloses a multi-component waste gas online monitor, and relates to the technical field of waste gas monitors, the multi-component waste gas online monitor comprises an outer shell, a detection assembly and a second gas transmission assembly, the outer side of the front part of the outer shell is connected with a display screen, the outer side of the top of the outer shell is provided with a gas suction assembly, and the inner side of the gas suction assembly is connected with a gas transmission pipe; and a first gas conveying assembly is arranged at the tail end of the gas conveying pipe. According to the device, the rotating disc can be manually shifted to drive the exhaust pipe to rotate, after the exhaust pipe rotates, the exhaust pipe can be connected with different gas conveying pipes, the number of the gas conveying pipes, the number of the first gas conveying assemblies and the number of the communicating pipes are all four, and each gas conveying pipe is connected with one group of the first gas conveying assemblies and the communicating pipes; the multiple gas conveying channels are arranged in the equipment, other gas conveying channels can be replaced for working before waste gas in one gas conveying channel is pumped away, the use gap of the equipment can be greatly shortened, and the working efficiency of the equipment can be improved.

Description

technical field [0001] The invention relates to the technical field of exhaust gas monitors, in particular to a multi-component exhaust gas on-line monitor. Background technique [0002] The exhaust gas monitor is an analyzer used for the detection of multi-component gases. The exhaust gas monitor is based on the principle of infrared absorption of gas, that is, gas molecules composed of polyatoms absorb infrared light energy within a certain wavelength range Working in direct proportion to the gas concentration, the exhaust gas monitor is usually used to measure the concentration of HC, CO, CO2, O2 in the exhaust gas of the gasoline engine of the motor vehicle. [0003] During the exhaust gas detection process of the exhaust gas monitors on the market, the exhaust gas will accumulate a little in the pipeline. Considering the accuracy of the exhaust gas detection, after an exhaust gas detection, it usually needs to stand for a while, and the internal air extraction device wi...

[0003] During the exhaust gas detection process of the exhaust gas monitors on the market, the exhaust gas will accumulate a little in the pipeline. Considering the accuracy of the exhaust gas detection, after an exhaust gas detection, it usually needs to stand for a while, and the internal air extraction device will The next test can only be carried out after all the internal exhaust gas is extracted, which has a great impact on the efficiency of exhaust gas detection
