Water-dust-oil automatic separation device for gas sampling

Abstract

The invention relates to the field of dust-laden gas sampling detection, and in particular to a gas impurity automatic separation device. The water-dust-oil automatic separation device for gas sampling comprises a horizontal main pipe section, one end of the horizontal main pipe section is a sampling pipe access port, and the other end of the horizontal main pipe section is a blast furnace gas interface; a separating inclined pipe connected to the horizontal main pipe section obliquely inserts into the horizontal main pipe section from below; using the flow direction of the gas as the forward direction, the axis of the separating inclined pipe and the axis of the horizontal main pipe section angle form an acute angle; the inlet of the separating inclined pipe is provided with a deceleration folded plate, and the deceleration folded plate is uniformly distributed with gradually expanding holes inclining downward; and a clean gas outlet is arranged on the side wall of the separating inclined pipe positioned in the outlet straight pipe section. The invention realizes the removal of impurities in the dust-laden blast furnace gas dust, and avoids the secondary pollution due to untimely treatment of the impurities separated by the device. The device has the advanategs of simple structure, convenient installation and maintenance, high reliability, and good promotion and application space.

Description

Technical field [0001] The invention relates to the field of dust-containing gas sampling and detection, in particular to an automatic separation device for gas impurities. Background technique [0002] In power plants, whether it is a coal-fired unit or a gas-fired unit, a large amount of coal gas will be used as the initial fuel and full fuel. In the process of combustion automation control, data collection is very important, it involves the safety of the generator set with the ratio of gas and air volume combustion, and the economy of boiler combustion. [0003] In actual work, because of the problems of dust, water and tar contained in the attached products of steel mills BFG and COG, the sampling points for pressure and flow will be disassembled and cleaned during maintenance, but after a period of operation The signal will tend to be abnormal, so how to ensure that the sampling system can maintain a normal maintenance cycle is our constant exploration. Summary of the invent...
