Abstract
The utility model provides a powder coarse particle separating device. The device is used for solving the problems that fine powder production materials contain a large amount of coarse particle matter, during the pneumatic conveying, a filter net is prone to being blocked or penetrated, a folded plate is damaged due to high-pressure impact of large-particle impurities, service life of the folded plate is shortened, maintenance cost is high, conveying resistance is large and energy consumption is high. The powder coarse particle separating device comprises a separator cylinder, the upper portion of the separator cylinder is connected with a hitting cylinder coaxial with the separator cylinder, the separator cylinder is provided with a fine powder inlet and a fine powder outlet which are located in the two sides of the hitting cylinder respectively, the lower portion of the separator cylinder is provided with a coarse particle impurity outlet, and the bottom of the separator cylinder is connected with a fluidization bed which is connected with a fluidization air chamber. The powder coarse particle separating device is used for coarse particle separation of the fine powder materials during the pneumatic conveying.
Description
Technical field:
The utility model relates in a kind of powder strength conveying, the powder coarse granule is carried out the device of separating and filtering.
Background technology:
Outsourcing fine-powdered production material and actual production require exists gap, contains a large amount of coarse particulate matter in the material, can cause the impacts such as bite, wearing and tearing to the slewing in the follow-up producing process.If being carried out separately the thickness powder, material separates, not only time-consuming, effort and but also need suitable place.For example in energy company's desulfurizer, raw material adopt the calcium lime powder raw material of granularity＜1mm, and deliver in the material reserving chamber by pneumatic conveying mode.In the quick lime raw material of buying, often there is particle diameter＞1mm, even contains particle diameter greater than the large granular impurity more than the 10mm.After these large granular impurities enter system, particularly in the rear operation slewing, easily produce bite and serious wearing and tearing.Often therefore produce the repairing operation such as desulfurization island rotary feeder, screw(-type) feeder, digester etc.If therefore coarse granule impurity can be filtered out by filter, just can solve well the problem of slewing bite and wearing and tearing.If in filter, adopt filter screen or folding phase-plate to come these bulky grains of filtering assorted, because the material of carrying is solid-state, and carrying is to carry by strength, in course of conveying, easily cause filter net jam or puncture, and the folding phase-plate is because the large granular impurity impacting with high pressure, make its folding phase-plate damage, cause reduce its service life, maintenance cost is high, and transporting resistance is large, energy consumption is high.
The utility model content:
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of powder coarse particle separating device, granular material is carried out that the thickness powder separates or impurity separates in strength is carried.
Above-mentioned purpose realizes by following technical scheme:
The powder coarse particle separating device, comprise Membrane Separator Cylinder for CFB Boiler, described Membrane Separator Cylinder for CFB Boiler top connects the bump cylinder coaxial with it, be provided with the outlet of fine powder material import and fine powder material on the described Membrane Separator Cylinder for CFB Boiler, described fine powder material import and the outlet of described fine powder material are positioned at the both sides of described bump cylinder, described Membrane Separator Cylinder for CFB Boiler bottom is provided with the outlet of coarse granule impurity, and described Membrane Separator Cylinder for CFB Boiler bottom connects fluid bed, and described fluid bed connects the fluidisation air chamber.
Described powder coarse particle separating device, the external diameter of described bump cylinder are 2～3 times of caliber of described fine powder material import, and the degree of depth of described bump cylinder is 3～4 times of caliber of described fine powder material import; 3～4 times of the caliber that described Membrane Separator Cylinder for CFB Boiler internal diameter is described fine powder material import, the top of described Membrane Separator Cylinder for CFB Boiler to the distance of described fluid bed is more than 6 times of caliber of described fine powder material import.
Beneficial effect:
1. the utility model adopts extra heavy pipe footpath and vertical depth design with Membrane Separator Cylinder for CFB Boiler, has greatly improved flow area, and reduces the flow velocity of Dual-Phrase Distribution of Gas olid in separator.
2. the utility model by the board-like drum type brake that is designed to, has guide functions with impacting tube, can greatly improve the air-flow operating mode of gas-powder flow.The bottom mounting design dust fluidizing device, prevent the particle dust sedimentation and stop up.The bottom has been installed drain hole and can regularly large granular materials in the cylinder have been cleared up, and safeguards simple.
Behind the utility model fluid bed fluidized wind flow velocity general control about 4m/s, more than the bleed pressure 0.4MPa, by flow velocity behind the control flow-control fluid bed.Can after opening the cartridge filter top, observe the fluidized wind effect at the scene, blowed floating with fine powder material, and the coarse granule material keep sedimentation for requiring, to the rear record control valve opening that meets the demands to debugging.
4. the utility model is simple in structure, and is safe and reliable, and water conservancy diversion is effective, and gas-flow resistance is low, be difficult for to stop up, and this device is not installed is compared and imports and exports basic non-resistance pressure reduction, good filtration effect.Under exerting oneself equally, grain graininess＜1mm can filter substantially.Because fluidizer is equipped with in the bottom, therefore can not produce clogging.
