Problems solved by technology

[0005] In order to solve the problem of low efficiency of impact separation in existing dual-channel separators, the present invention provides a dual-channel rotary-inertial coarse powder separator. The dual-channel rotary-inertial coarse powder separator changes impact separation into centrifugal separation Main, and increase the fluidization wind, so that the separation efficiency is higher and the uniformity index is higher

Embodiment approach

[0037] Method 1: Gas and solids enter through the gas-solid inlet pipe 1, and pass through the impurity removal part 10 in the gas-solid inlet pipe 1. If the vertical rotating blades are used to remove soft substances, the centrifugal force and primary separation are mainly generated. The gas-solid produces a swirling flow field, and the coarse powder spins to the wall of the inner shell 8 to be separated, and is discharged from the powder return pipe 9, and the qualified fine powder goes out from the outlet 3.

[0038] Method 2: Gas and solids enter through the gas-solid inlet pipe 1, and pass through the impurity removal part 10 in the gas-solid inlet pipe 1. If the vertical rotating blades are used to remove soft substances, the centrifugal force and primary separation are mainly generated. Make the gas and solid generate a swirling flow field, and then pass through the small baffle plate 6 to produce two-stage separation. The coarse powder is rotated to the wall of the inne...

Abstract

The invention provides a dual-channel rotation inertia coarse powder separator. The dual-channel rotation inertia coarse powder separator comprises an outer shell (2), an inner shell (8) and a gas and solid inlet pipe (1) which are all sequentially arranged in a sleeved manner from outside to inside; the inner shell (8) and the gas and solid inlet pipe (1) are each of a cylindrical structure with the upper end and the lower end open; an outer annular cavity is formed between the outer shell (2) and the inner shell (8); an inner annular cavity is formed between the inner shell (8) and the gas and solid inlet pipe (1); the lower portion of the outer shell (2) is connected with a powder returning pipe (9); and the upper portion of the outer shell (2) is connected with an outlet (3). According to the dual-channel rotation inertia coarse powder separator, the impacting separation is mainly changed into centrifugal separation, fluidizing air is added, the separation efficiency is higher, and the uniformity index is higher.

Description

technical field [0001] The invention relates to the field of supporting equipment such as thermal power generation, cement, chemical industry, metallurgy, etc., in particular to a dual-channel rotary inertial coarse powder separator. Background technique [0002] Coarse powder separator is an important equipment in the pulverizing system. Its main function is to separate the qualified fine powder and return the unqualified coarse powder to the mill for regrinding. It is widely used in power plants, cement industry, chemical industry, and metallurgical industry. At present, the existing dual-channel separators are mainly used in fan coal mills, and are mainly separated by inertia and impact. The internal structural parts are easy to wear and soft materials are easy to stay in the internal parts, which affects the separation performance and further affects the performance and safety. , In addition, the separation efficiency of the separator is poor, the powder is coarse, the u...
