Abstract

The utility model relates to an inlet pipe for smoke machines. Two balancing ring expansion joints are arranged at a horizontal smoke pipe which is close to an inlet of the smoke machine, and the connection of an inlet of the smoke machine is changed to a flexible joint. In this way, the horizontal and vertical dislocation, deflection, deformation, sedimentation, etc. of the inlet pipe have small influence on the smoke machine, and thereby, the smoke machine safely runs with long period. A horizontal smoke pipe adopts a spring suspender and a central roller support, and the friction resistance generated by the thermal expansion the pipe when moving is reduced. The thermal compensation of the pipe adopts a triple hinged expansion joint or triple balancing ring expansion joint, and the influence of the thermal expansion of the pipe to the smoke machine can be absorbed. The utility model has high adaptability of the manufacture, the installation error, the foundation settlement, the deformation of the suspension centre of the pipe, the thermal expansion motion of the pipe, etc; thus, the capability of the normal running of the smoke machine is enhanced.

Description

Inlet pipe for smoke machine

The utility model belongs to the improvement of flue gas turbine inlet tubular construction.

At present, the cigarette unit that has used, its inlet duct all only designs by the thermal compensation requirement, the three hinge expansion joint schemes that adopt more, (or four hinge expansion joint schemes), make pipeline to making, alignment error, foundation settlement, the pipeline hanger, adaptive capacitys such as deformation of timbering are all lower, so it is high especially to making installation requirement, the Concentricity tolerance of pipeline and cigarette machine is less than 1 millimeter, flange nonparallelism deviation is less than 0.5 millimeter, and these reach after requiring to adjust meticulously through strict manufacturing installation and before going into operation substantially, but time-consuming, effort, and the precision that its cold conditions is adjusted, when entering 700 ℃ of operation condition attitudes, because the moving of heat expansion pipeline, its accuracy changes, therefore, the cycle of most cigarette unit continued operation is not oversize.

The purpose of this utility model provides and a kind ofly the adaptive capacity height such as moves to making alignment error, foundation settlement, the distortion of pipeline suspension centre, deformation of timbering, thermal expansion of pipeline, the flue gas turbine inlet pipe that the ability of the normal operation of cigarette machine is increased greatly.

The utility model is achieved in that at horizontal smoke pipe and is provided with two gimbal expansion joints near the flue gas turbine inlet place, being connected to become and being flexible coupling cigarette machine and inlet duct, like this flue gas turbine inlet pipeline laterally, the dislocation on the vertical direction, deflection, distortion sedimentation etc. are to the influence of cigarette machine, by two gimbal expansion joints it is reduced greatly, thereby make cigarette captain cycle safe operation; Have the center roller support at the horizontal smoke pipe in two gimbal expansion joints left sides, the horizontal smoke pipe on two gimbal expansion joint right sides adopts three springs to hang, the frictional resistance when being used to reduce thermal expansion of pipeline and moving; Be the extraction duct thermal expansion, adopt hinge expansion joint or gimbal expansion joint as thermal compensation device, on near smoke pipe pipe bent position and vertical smoke pipe, be provided with 3 hinge expansion joints or 3 gimbal expansion joints, also can be according to instructions for use, be provided with a hinge near horizontal smoke pipe pipe bent position, vertically be provided with 2 gimbal expansion joints on the smoke pipe, influences such as the displacement that thermal expansion of pipeline is produced, distortion, distortion by hinge expansion joint or gimbal expansion joint, be eliminated, guarantee that the cigarette machine normally moves.

Compared with the prior art the utility model has making alignment error, foundation settlement, suspension centre distortion, deformation of timbering, thermal expansion of pipeline adaptive capacity advantages of higher, and the ability of the normal operation of cigarette machine is increased greatly.

Below in conjunction with accompanying drawing the utility model is explained

Accompanying drawing is a flue gas turbine inlet tubular construction schematic diagram

Referring to accompanying drawing: the flue gas turbine inlet pipe by horizontal smoke pipe 3 and vertically smoke pipe 9 form, near the flue gas turbine inlet place two gimbal expansion joints 6 are installed at horizontal smoke pipe 3, the horizontal smoke pipe 3 that is arranged with center roller support 2, two gimbal expansion joints 6 right sides at the horizontal smoke pipe 3 in two gimbal expansion joints, 6 left sides adopts three springs to hang 7; For eliminating the influence of thermal expansion of pipeline, on near smoke pipe pipe bent position and vertical smoke pipe, 3 hinge expansion joints or 3 gimbal expansion joints 8 are installed, according to instructions for use, also can a hinge expansion joint be installed near horizontal smoke pipe pipe bent position, vertically on the smoke pipe 2 gimbal expansion joints are being installed; Gate valve 4 and dish valve 5 are installed on horizontal smoke pipe 3.
