Gas Sampling Dust Water Oil Automatic Separation Device

Abstract

The invention relates to the field of dusty gas sampling and detection, in particular to an automatic separation device for gas impurities. An automatic dust-water-oil separation device for gas sampling, comprising a horizontal main pipe section, one end of the horizontal main pipe section is a sampling pipe inlet, the other end of the horizontal main pipe section is a blast furnace gas interface, and the horizontal main pipe section is connected with a separation inclined pipe, The separation inclined pipe is obliquely inserted into the horizontal main pipe section from below; with the gas flow direction as the positive direction, the axis of the separation inclined pipe forms an acute angle with the axis of the horizontal main pipe section, and the entrance of the separation inclined pipe is provided with a deceleration fold The deceleration folded plate is evenly distributed with downward-sloping gradually expanding air holes, and the side wall of the separation inclined pipe located in the outlet straight pipe section is provided with a clean gas outlet. The invention realizes the removal of impurities from the dusty blast furnace gas and avoids secondary pollution caused by untimely treatment of the impurities separated by the device. The invention has the advantages 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 dusty 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 gas will be used as the initial fuel and the full fuel. In the combustion automation control process, data collection is very important, it involves the safety of the generator set with the ratio of gas and air volume combustion, and it involves the economy of boiler combustion. [0003] In actual work, because the by-products BFG and COG of the steel mill have serious problems of dust, water, and tar, the pressure, flow, and other sampling points will be disassembled and cleaned during maintenance, but after a period of operation The signal tends to be abnormal, so how to ensure that the sampling system can maintain a normal maintenance cycle is what we are constantly exploring.
