Abstract

The invention provides a gas dust-removing and sampling device. The gas dust-removing and sampling device comprises a first shell and a second shell arranged in the first shell, wherein an air inlet is formed in one end of the first shell and the other end of the first shell is a dust exhausting end; an air inlet is formed in one end of the second shell and a filtering sieve is arranged at the air inlet of the second shell; an air outlet is further formed in the second shell; the air outlet penetrates through the first shell. According to the gas dust-removing and sampling device, a second exhausting screw propeller is rotated under the driving of a motor to reduce the pressure in the first shell into negative pressure, so that external gas to be analyzed is pumped into the second shell through the filtering sieve; the gas to be analyzed enters the dust exhausting end from dust falling from the filtering sieve and does not enter the second shell from a gap between the filtering sieve and the second shell, so as to prevent dust pollution of filtered gas and also prevent the dust from being blocked between the filtering sieve and a gas channel in the second shell; the on-line analysis of the gas is easy to realize.

Description

Technical field [0001] The invention belongs to the field of spectral online analysis of gas composition and concentration, and specifically relates to a gas dust removal and sampling device. Background technique [0002] Infrared spectroscopy can almost achieve the quantitative analysis of all polar gases, and neither consumes any materials nor produces any waste during the working process. It can also work for a long time and has low maintenance costs. Therefore, it is an important part of gas online analysis. method. With the development of computer technology and data analysis and processing technology, in recent years, spectrometers have begun to be used in the field of online analysis of gas composition and concentration, such as exploration well gas logging, atmospheric environment monitoring, online monitoring of mine gas composition and its concentration, Fields such as online detection of characteristic gases in power equipment. Since infrared spectroscopy is based on...
