Embodiment Construction

[0012] The principle of flow mechanics is used to optimize the design of a device for removing water vapor, which can condense water vapor in time and automatically remove it, so as to ensure that water vapor does not enter the optical sensor.

[0013] Such as figure 1 As shown, the device for removing water vapor in the automobile exhaust gas analyzer includes an air chamber 1 and a drain pipe 2, the air chamber 1 is cylindrical, the bottom of the air chamber 1 is connected to the drain pipe 2, and a side wall of the air chamber 1 is provided The air inlet 3 is provided with an air outlet 4 at the position opposite to the air inlet 3 on the side wall of the air chamber. 5. The gas flow rate entering the gas chamber is particularly large, while the gas flow rate at the gas outlet suddenly decreases, causing the water vapor in the gas to be retained, condensed, and quickly discharged from the instrument.

[0014] In application, the gas flow rate of the gas outlet 4 is change...

Abstract

The invention provides a design method of a built-in steam condensation removal device for automobile exhaust analysis, comprising an air chamber and a drain pipe, wherein the bottom of the air chamber is connected with the drain pipe, the side wall of the air chamber is provided with an air inlet, the position on the side wall of the air chamber, which is opposite to the air inlet, is provided with an air outlet, the elevation of the air outlet is higher than that of the air inlet, and the pipeline of the air outlet is also provided with an air-resistor. The air flow of the air outlet is changed by regulating the air-resistor, so that flow of air entering the air chamber is very large, and the air flow of the air outlet suddenly becomes small; air in the air chamber generates eddy current; and steam in the air is detained, condensed and discharged in time so as to ensure that steam does not enter an optical sensor.

Description

technical field [0001] The invention relates to a design method of a built-in water vapor condensation removal device in automobile tail gas analysis, and belongs to the technical field of detection equipment. Background technique [0002] The automobile exhaust analyzer uses non-dispersive infrared method (NDIR) to detect HC, CO, CO in automobile exhaust. 2 , O 2 , NOX and other harmful gas concentration detection equipment. Due to the high temperature of the automobile exhaust pipe, the exhaust gas contains a large amount of water vapor, and the optical detection method is particularly sensitive to water vapor. Water vapor will not only affect the detection accuracy, but also damage the optical sensor. At present, the automobile exhaust gas analyzer usually adds a condenser and an oil-water separator used on a refrigerator to the input of the exhaust gas. This method has a large volume and high cost. Contents of the invention [0003] The purpose of the present invent...
