Embodiment Construction

[0022] The anti-blocking pressure-taking pipe of the dense gas-solid flow device of the present invention is composed of an inclined pipe, a positioning ring, a bent pipe, a high-pressure gas blowing pipe, a horizontal pipe, a threaded joint and a support frame. Among them, the inclined pipe is located at the front end of the pressure taking pipe, and the positioning ring is set on the inclined pipe. The inclined pipe and the horizontal pipe are connected by an elbow. Between the nozzle of the high-pressure blowing pipe and the air outlet. The inclination angle of the inclined tube is 75°; the front end of the inclined tube is a tongue-shaped pressure-taking port, and the upper 3 / 4 area of ​​the tongue-shaped pressure-taking port is an orifice plate with air holes on the orifice plate, and the lower part of the tongue-shaped pressure-taking port is 1 / 4 The area 4 is the discharge opening; the outer wall of the second half of the inclined pipe is marked with a scale. The posit...

Abstract

Anti-clogging pressure-taking pipe of dense gas-solid flow device and its application method Insert the inclined pipe (1) into the pressure measuring port (23) with an inclination angle of 75° on the wall (22) of the dense gas-solid flow device, and the positioning ring (2 ) rubber ring (12) is in close contact with the outer wall surface (24) of the dense gas-solid flow device, the length of insertion is adjusted and positioned according to the scale marked on the inclined tube (1), and the threaded joint (6) passes through the thick rubber tube (26 ) is connected with the pressure pulsation testing device, and the threaded section (20) of the high-pressure air blowing pipe (4) is connected with the high-pressure air source through a thin rubber tube (25), and the double anti-blocking measures effectively solve the problem of blocking the pressure-taking pipe.

Description

technical field [0001] The invention relates to an anti-blocking pressure-taking pipe of a dense gas-solid flow device and an application method thereof, belonging to the technical field of multiphase flow measurement. Background technique [0002] Dense gas-solid flow devices are widely used in physical and chemical processes in the fields of chemical industry, petrochemical, metallurgy, energy, materials, biochemistry, environmental protection, and pharmaceuticals. The pressure pulsation signal of the dense gas-solid flow device contains a lot of dynamic information, which is a comprehensive reflection of various factors such as particle characteristics, geometric characteristics of the gas-solid flow device, and bubble movement characteristics. The pressure pulsation signal at different positions in the bed, from different Time and space reflect the characteristics of gas-solid flow, and play an important role in the safe, stable and optimal operation of dense gas-solid f...
