Gas-solid mixing conveying device capable of achieving even distribution and application of gas-solid mixing conveying device

Abstract

The invention provides a gas-solid mixing conveying device capable of achieving even distribution and application of the gas-solid mixing conveying device. According to the gas-solid mixing conveying device, a single horizontal pipeline is manly composed of a sand feeding segment, reducing and enlarging segments, a rectification segment and an outlet segment, all of which are connected in sequence; the sand feeding segment is a tee joint, a horizontal pipeline part of the sand feeding segment is mainly composed of straight pipelines at the two ends, a straight pipeline in the middle and variable-sectional pipelines at the two ends and the middle, and a vertical pipeline part of the sand feeding segment is inserted in the straight pipeline close to the center of the horizontal pipeline part; each reducing and enlarging segment is mainly composed of straight pipelines at the two ends, a straight pipeline in the middle and variable-sectional pipelines at the two ends and the middle; the outlet segment is an annular expansion nozzle; and multi-layer rectification nets are arranged between the sand feeding segment, the reducing and enlarging segments, the rectification segment and the outlet segment. The gas-solid mixing conveying device can be applied to mixing of solid particles (fine particles) of 1-200 micrometers and gas flow, and fine grains entering in the radial direction are homogenized at an axial and circumferential outlet to enter an annular channel of a particle separator.

Description

technical field [0001] The invention relates to a gas-solid mixing conveying device capable of realizing uniform distribution and its application. Background technique [0002] At the inlet of the engine, in order to prevent the entry of dust, leaves, grass roots, stones and even birds in the air, blocking devices, such as partitions and mesh covers, are usually added to separate large particles. For small particles, a guide device can be added at the inlet of the engine, and the inertia can be used to separate the solid particles in the airflow. separated into the bifurcated channel). [0003] The performance test of inertial particle separator is an effective measure to verify its gas-solid separation. In the test, the inlet environment of the inertial particle separator needs to create uniformly distributed sand and dust inlet conditions, so it is necessary to configure a gas-solid (gas solid particle) mixing device that can achieve uniform distribution.

Problems solved by technology

Circumferential ejection is to arrange a certain number of nozzles at each circumferential angular position in the annular channel of the particle separator to achieve the purpose of uniformity. This device will inevitably affect the resistance distribution of the inlet channel of the particle separator, resulting in an increase in its flow resistance. , while affecting the airflow distribution in the channel
