Problems solved by technology
[0006] 1. The moisture content in the exhaust gas cannot be monitored in real time online, or the moisture content measured only by the moisture content sensor is not accurate enough;
[0007] 2. The dust or ash layer in the exhaust gas is likely to interfere with the determination of the moisture content;
[0008] 3. The sampling point of the exhaust gas to be tested is single, and accurate sampling cannot be achieved for some large-section smoke and gas discharge outlets;
[0009] 4. The installation and disassembly of the equipment is inconvenient, and it is not easy to clean

The invention discloses an exhaust gas moisture content determination device. The device comprises a sampling head, a solid-gas separator, a sampling pump, a heating sleeve, a water absorber, a bufferchamber, a one-way valve and a flowmeter which are connected with one another through gas-guide pipes in the exhaust gas flow direction; a first temperature sensor and a first moisture sensor are arranged on the gas-guide pipe between the heating sleeve and the water absorber; the water absorber is arranged in an incubator body, and the water absorber and the incubator body are placed on an electronic scale; a second temperature sensor is arranged on the incubator body; a pressure sensor is arranged on the gas-guide pipe between the water absorber and the buffer chamber; a second moisture sensor is arranged on the buffer chamber; the sampling pump, the heating sleeve, the water absorber, the first temperature sensor, the first moisture sensor, the electronic scale, the second temperaturesensor, the pressure sensor and the second moisture sensor are all connected with the control box. Accordingly, the measured moisture content is more accurate; interference is small, convenience is brought to cleaning, and disassembling is not needed.
Description
technical field [0001] The invention relates to the field of environmental monitoring equipment, in particular to a device for measuring the moisture content of waste gas. Background technique [0002] In recent years, air pollution has become more and more serious, and the occurrence frequency of smog has become more and more frequent. People's calls for environmental pollution control have become stronger and stronger. According to a comprehensive analysis, the degree of air pollution depends on the quality of the atmosphere. The key factor of air quality is the emission and concentration of soot and flue gas from boilers. [0003] There are three main sources of moisture in the flue gas: 1. The moisture carried by the air blown into the boiler during combustion; 2. The water vapor formed by the evaporation of the fuel in the form of bound water or external water during the combustion process; 3. Hydrocarbons contained in fuel are oxidized to produce water during combusti...
