Pressure-stabilizing and air-controlling device for inflatable beam of grate cooler

Abstract

The invention discloses a pressure-stabilizing and air-controlling device for an inflatable beam of a grate cooler. The pressure-stabilizing and air-controlling device comprises a first mute diffuserpipe, a flow stabilizing pipe, a second mute diffuser pipe, a rectifying and pressure-stabilizing pipe and pressure dividing pipes; the first mute diffuser pipe and the second mute diffuser pipe are both of a V-shaped body structure; the large end of the first mute diffuser pipe is connected with the small end of the second mute diffuser pipe through the flow stabilizing pipe; the large end of thesecond mute diffuser pipe is connected with the at least two pressure dividing pipes; a rectifying and pressure-stabilizing impeller is arranged in the rectifying and pressure-stabilizing pipe; a main shaft is fixedly installed in the middle of the rectifying and pressure-stabilizing impeller and rotationally installed in the rectifying and pressure-stabilizing pipe; a driving motor and a speed reducer are fixedly installed at the outer side of the rectifying and pressure-stabilizing pipe; an output shaft of the driving motor is connected with an input shaft of the speed reducer; and an output shaft of the speed reducer is fixedly connected with the main shaft. The pressure-stabilizing and air-controlling device is simple in structure and easy to machine and manufacture, and the air pressure of air blown out of the pressure dividing pipes is uniform and stable.

Description

technical field [0001] The invention relates to the technical field of material layer cooling and heat exchange on the grate bed of a grate cooler, in particular to a pressure-stabilizing and wind-controlling device for an inflatable beam of a grate cooler. Background technique [0002] The grate cooler is an important main equipment in the clinker firing system of a cement plant. Its main function is to cool and transport cement clinker; at the same time, it provides hot air for the rotary kiln and calciner, and is the heat recovery mechanism of the firing system. Major equipment. [0003] At present, the air supply system of the third-generation grate cooler inflatable beam has uneven fan supply. The wind in the inflatable beam of the grate cooler is sometimes large and some is small. Part of the material layer is blown through, no wind, and the heat transfer effect of clinker Not good, the reason is that the gas is unevenly distributed from the fan outlet to the inlet of...

Problems solved by technology

[0003] At present, the air supply system of the third-generation grate cooler inflatable beam has uneven fan supply. The wind in the inflatable beam of the grate cooler is sometimes large and some is small. Part of the material layer is blown through, no wind, and the heat transfer effect of clinker Not good, the reason is that the gas is unevenly distributed from the fan outlet to the inlet of the inflatable beam, and the dynamic pressure loss of the fan outlet pipe is also large

[0004] The current domestic practice is to connect a straight pipe from the outlet of the fan, and separate several pressure-dividing pipes when it is close to the grate cooler. At different times, the gas tends to flow out of the inflatable beams with relatively low pressure, which will easily cause the clinker on the grate bed to blow through. no cooling effect
