Description

Lime thickness rotary separation device

Technical Field

The utility model relates to a lime thickness separation technical field specifically is lime thickness rotation separation device.

Background

The dry desulfurization is one of the main processes of flue gas desulfurization, and has the advantages of low investment, small occupied area, water saving, energy saving, no wastewater discharge and the like. The main structures of the dry desulfurization process comprise an absorbent bin, an absorption tower, a bag-type dust remover and the like, wherein slaked lime is usually used as the absorbent for desulfurization, and the absorbent is stored in the absorbent bin. And slaked lime used by a part of desulfurization factories is digested by outsourcing quicklime in a plant digestion station, then is conveyed to an absorbent bin for storage, and then is added into an absorption tower according to the requirement of each set of desulfurization device. One part of manufacturers directly purchases slaked lime or carbide slag as a dry desulphurization absorbent.

Part of desulfurization using factories are limited by absorbent sources or cost considerations and the like, most desulfurization uses absorbent with quality lower than that of dry desulfurization, and the absorbent with low quality is often doped with more coarse particle impurities. In addition, desulfurization manufacturers are unaware of the damage of low quality absorbents to dry desulfurization equipment. The quality of the absorbent not only affects the flue gas desulfurization efficiency, but also directly affects the service life of the absorption tower, so that the operation, maintenance and management cost of the whole desulfurization is increased, and therefore, the quality requirement of the source absorption tower is one of the necessary conditions of the dry desulfurization process.

Through the research on the existing lime thickness separation device, the existing lime thickness separation device mainly comprises a stainless steel vibrating screen, a linear vibrating screen, an ultrasonic vibrating screen and the like. The vibrating screen operates by utilizing reciprocating rotary type vibration generated by vibrator excitation. The upper rotary heavy hammer of the vibrator makes the screen surface generate plane rotary vibration, the lower rotary heavy hammer makes the screen surface generate conical surface rotary vibration, and the combined effect makes the screen surface generate re-rotary vibration. But the vibration of the machine during operation causes the materials to be more tightly adhered to the screen surface, thereby causing material jam or being forced to stop. Due to the limitation of the working principle, the energy consumption of the vibrating screen is relatively high, especially under the working condition of high output. In addition, the working noise and dust are heavy, and the use is inconvenient.
