Description
Technical field
The present invention relates to storage facilities field, particularly relate to a kind of large-scale fluidization storehouse for storing granular material.
Background technology
At present, large-scale fluidization storehouse is broadly divided into concrete storehouse and two kinds of steel plate storehouse, storehouse body is cylindrical, it has the features such as amount of storage is big, steadiness is good, it is widely used in the storage of the granular material such as cement, flyash, typical large-scale fluidization storehouse as disclosed in Chinese patent that application number is 200620158729.2. Practical application finds, this type of large-scale fluidization storehouse has a disadvantage in that the equipment such as dust-precipitator are fit directly on the body of storehouse by (1), although bank generally maintains closing, but also far do not reach the level of sealing, therefore, pan feeding process needs rely on external force to send in bank by material, discharging process cannot keep in bank discharge pressure, deadweight and the activation source of the gas that can only rely on material provide power, and no matter pan feeding or discharging can consume bigger; (2) owing to storehouse body is larger in size, practice must be provided with multiple discharging opening, during discharging, once the material of certain discharging opening has first gone out, it is formed for pressure relief channels, weaken the activation effect of activation source of the gas, affect the discharging effect of other discharging openings, also increase energy consumption level further simultaneously; (3) dust-precipitator is arranged on the body of storehouse and is only capable of the dust in collection bank, but during materiel warehouse-out, the quick-fried dirt being externally formed with due to storehouse inside and outside differential pressure but cannot be recovered, it is easy to causes environmental pollution; (4) owing to bank sealed horizontal is poor, the material of its storage easily produce hardening harden and air produce chemical reaction cause the problems such as activity decrease.
In sum, market is in the urgent need to providing a kind of new-type big shape fluidization storehouse being able to ensure that the storage stability of material, energy consumption are low and more environmentally-friendly.
Summary of the invention
First of the present invention aims to overcome that drawbacks described above, it is provided that a kind of energy-conserving and environment-protective, and is able to ensure that the large-scale closed fluidization storehouse system of storage material stability.
The large-scale closed fluidization storehouse system of the present invention is realized in, including storage warehouse, pan feeding pipeline, discharging pipeline, material lift equipment, storehouse in bulk and dust arrester installation, storage warehouse includes the activation compressed air source unit that storehouse body, base structure and base structure upper surface are arranged, dust arrester installation includes dust-precipitator and air-introduced machine, and storage warehouse is closed structure; One end of pan feeding pipeline is connected with storage warehouse at body top, storehouse, and pan feeding pipeline is provided with pan feeding flow control valve; One end of discharging pipeline is connected with storage warehouse in the bottom of storehouse body or the bottom of storage warehouse, and the other end of discharging pipeline is connected with material lift equipment, and discharging pipeline is provided with reactor effluent stream control valve; Material lift equipment is connected with storehouse in bulk, dust arrester installation is arranged on the top in storehouse in bulk, it is connected respectively through the pipeline that gathers dust between dust arrester installation with material lift equipment and storage warehouse, and the pipeline that gathers dust between dust arrester installation and material lift equipment and storage warehouse is respectively equipped with flow control valve; Storage warehouse also sets up pressure monitoring device.
In the large-scale closed fluidization storehouse system of the present invention, base structure can include the flat bottom of the reservior directly landed, and activation compressed air source unit is arranged on the upper surface of flat bottom of the reservior, and discharging pipeline is connected with storage warehouse in the bottom of storehouse body side surface;Additionally, base structure can also include discharging gallery and comprise multiple cone and go out the bottom of the reservior of charge bank, activation compressed air source unit is arranged along the groove going out charge bank, and discharging pipeline is connected with storage warehouse in the bottom of storage warehouse; It addition, base structure can also include being provided with a cone goes out the bottom of the reservior of charge bank, activation compressed air source unit is arranged along the groove going out charge bank, and discharging pipeline is connected with storage warehouse in the bottom of storehouse body side surface.
