Large-scale closed fluidized storage and its application method

Abstract

The invention discloses a large airtight fluidization storage warehouse system, relates to the field of warehouse equipment, and particularly relates to a large fluidization storage warehouse for storing powdery materials and granular materials. The large airtight fluidization storage warehouse system disclosed by the invention comprises a storage warehouse, a charge pipeline, a discharge pipeline, material hoisting equipment, a bulk warehouse and a dust collection device, wherein the storage warehouse comprises a warehouse body, a warehouse bottom structure and an activated gas source device arranged on the upper surface of the warehouse bottom structure; the dust collection device comprises a dust collector and an induced draft fan; and the storage warehouse is of an airtight structure. The invention further provides an application method of the large airtight fluidization storage warehouse system. The large airtight fluidization storage warehouse system disclosed by the invention has the advantages of low warehouse building investment, low energy consumption of material warehouse-in and warehouse-out, excellent environmental protection performance, higher safety and the like, has great economical efficiency, practicability and safety, and can be widely applied to storage for powdery materials and granular materials such as coal ash and cement; and the application method of the large airtight fluidization storage warehouse system, which is disclosed by the invention, is easy to operate, simple and practicable, higher in warehouse-out rate, safe and reliable, and quite broad in market application prospect.

Description

technical field [0001] The invention relates to the field of storage equipment, in particular to a large-scale fluidized storage for storing powder and granular materials. Background technique [0002] At present, large-scale fluidized storage is mainly divided into two types: concrete storage and steel storage. The storage body is cylindrical. It has the characteristics of large storage capacity and good stability. The storage of materials is typically a large fluidized storage warehouse disclosed in Chinese Patent Application No. 200620158729.2. In practical application, it is found that this kind of large-scale fluidized storage has the following disadvantages: (1) The dust collector and other equipment are directly assembled on the storage body. Although the storage is generally kept closed, it is far from being sealed, so , during the feeding process, it is necessary to rely on external force to send the material into the storage. During the discharging process, the st...

In practical application, it is found that this kind of large-scale fluidized storage has the following disadvantages: (1) The dust collector and other equipment are directly assembled on the storage body. Although the storage is generally kept closed, it is far from being sealed, so , during the feeding process, it is necessary to rely on external force to send the material into the storage. During the discharging process, the storage can not maintain the discharge pressure. It can only rely on the self-weight of the material and the activated gas source to provide power. No matter whether it is feeding or discharging, it can (2) Due to the large size of the storage body, multiple outlets must be set in practice. When discharging, once the material of a certain outlet is discharged first, a pressure release channel will be formed to weaken the activated gas source. The activation effect of the material affects the discharge effect of other discharge ports, and further increases the energy consumption level; (3) The dust collector is set on the storage body and can only collect the dust in the storage, but when the material is discharged from the storage, Due to the pressure difference inside and outside the warehouse, the explosion dust formed outside cannot be recovered, which is likely to cause environmental pollution; (4) Due to the poor sealing level of the warehouse, the stored materials are prone to hardening and compaction, and chemical reactions with air lead to a decrease in activity, etc. question
