Abstract
The invention provides a technique for rising pipe pneumatic dilute-phase conveying. The technique comprises the steps that at first, solid powder from a feeding bin enters a riser reactor under effects of a feeding machine or gravity, forms a dilute phase with a conveying carrier gas, and rapidly passes a rising pipe under lifting of the conveying carrier gas; and secondly, the solid powder and the conveying carrier gas exit from the raising pipe and then directly enter a cyclone separator to carry out rapid separation, wherein the solid phase part of the cyclone separator is the solid power, and the gas phase part is the conveying carrier gas. According to the invention, the raising pipe is used for the pneumatic dilute-phase conveying; the solid power with a high flowing rate and a small concentration is not deposited easily, causes less wear to the pipe wall, and can be separated rapidly in the cyclone separator.
Description
Technical field
The present invention relates to a kind of conveying process, in particular it relates to a kind of riser strength diluted phase transport process。
Background technology
Strength diluted phase transport, carries also known as air-flow, is a kind of concrete application of fluidization technology, is the energy utilizing air-flow, along airflow direction conveying granular material in closed conduit。The simple in construction of strength diluted phase transport device, easy to operate, flat, vertical or incline direction conveying can be said, course of conveying can also carry out the heating of material, cooling simultaneously, physical operations or some chemical operation such as dry and air current classifying。
In strength diluted phase transport, solids flow rate is slow, it is easy to deposit in the duct；Adopt two-phase transportation tube wall can be produced bigger abrasion。And solids flow rate is slow or adopts two-phase transportation also can there is bigger difficulty in the gas solid separation of postorder。
Summary of the invention
For defect of the prior art, it is an object of the invention to provide a kind of riser strength diluted phase transport process, it adopts riser to carry out strength diluted phase transport, pressed powder flow velocity is fast, concentration is little, pressed powder will not produce deposition, and transducer wall ' s abrasion is little, is easily achieved sharp separation in cyclone separator。
According to an aspect of the present invention, a kind of riser strength diluted phase transport process is provided, it is characterized in that, comprise the following steps: step one, pressed powder from feeding chamber enters in riser reactor under batcher or action of gravity, dilute phase is formed with delivery of carrier gas, and under delivery of carrier gas castering action, quickly through riser；Step 2, pressed powder and delivery of carrier gas are out directly entered cyclone separator afterwards and realize sharp separation from riser, and the solid fraction of cyclone separator is pressed powder, and gas phase portion is delivery of carrier gas。
Preferably, described step one utilizes riser that pressed powder is carried out strength diluted phase transport。
Preferably, described delivery of carrier gas is air, nitrogen, carbon dioxide or mixing gas。
Preferably, the transporting pattern of described pressed powder is diluted phase transport, can occur or chemical reaction does not occur in course of conveying。
Preferably, described pressed powder flow velocity in riser is between 3m/s ~ 30m/s。
Preferably, described cyclone design be built-in multi-cyclone, external multi-cyclone or inside and outside the multi-cyclone that combines。
Compared with prior art, the present invention has following beneficial effect: the present invention adopts riser to carry out strength diluted phase transport, and pressed powder flow velocity is fast, concentration is little, pressed powder will not produce deposition, and transducer wall ' s abrasion is little, is easily achieved sharp separation in cyclone separator。Whole riser strength diluted phase transport unit according to the needs of concrete technology, reasonably can be changed, to match with integrated artistic by the present invention。
Accompanying drawing explanation
By reading detailed description non-limiting example made with reference to the following drawings, the other features, objects and advantages of the present invention will become more apparent upon:
Fig. 1 is the schematic diagram of riser strength diluted phase transport process of the present invention。
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail。Following example will assist in those skilled in the art and are further appreciated by the present invention, but do not limit the present invention in any form。It should be pointed out that, to those skilled in the art, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement。These broadly fall into protection scope of the present invention。
As it is shown in figure 1, riser strength diluted phase transport process of the present invention comprises the following steps:
Step one, the pressed powder from feeding chamber enters in riser reactor under batcher or action of gravity, forms dilute phase with delivery of carrier gas, and under delivery of carrier gas castering action, quickly through riser；Wherein, step one utilizes riser that pressed powder is carried out strength diluted phase transport, can occur or chemical reaction does not occur in course of conveying, and pressed powder will not deposit, and transducer wall ' s abrasion is little, carries out sharp separation afterwards。Delivery of carrier gas is air, nitrogen, carbon dioxide or mixing gas (mixing gas is other factory gas relevant with process matching, such as plant tail gas, off-gas, flue gas etc.)。The transporting pattern of pressed powder is diluted phase transport, and pressed powder will not deposit, and wall abrasion is little。Pressed powder flow velocity in riser is fast, and flow velocity is between 3m/s ~ 30m/s。Owing to pressed powder flow velocity is fast, gas flow is big, it is possible to realize sharp separation in cyclone separator。
Step 2, pressed powder and delivery of carrier gas are out directly entered cyclone separator afterwards and realize sharp separation from riser, and cyclone separator solid fraction is pressed powder, and gas phase portion is delivery of carrier gas。Needs according to technique, cyclone separator can be designed as built-in multi-cyclone, external multi-cyclone or inside and outside the multi-cyclone that combines。
Riser strength diluted phase transport process of the present invention includes following two parts:
(1) riser transport portion, pressed powder A1 enters in riser C2 from feeding chamber C1, delivery of carrier gas A2 enters from the bottom of riser C2, and pressed powder A1 and delivery of carrier gas A2 forms dilute phase, and quickly arrives the top of riser C2 under delivery of carrier gas castering action from the bottom of riser C2。
(2) cyclone separator separate section, delivery of carrier gas and pressed powder A3 enter cyclone separator C3 from the outlet of riser C2, and realize sharp separation in cyclone separator C3, the top exit material of cyclone separator C3 is delivery of carrier gas A4, and the outlet at bottom material of cyclone separator C3 is pressed powder A5。
The present invention adopts riser strength diluted phase transport process so that pressed powder is readily delivered, and solid will not deposit, and transducer wall ' s abrasion is little, and is easily isolated。Owing to adopting riser strength diluted phase transport method, pressed powder will not deposit, and pressed powder flow velocity is fast, it is possible to realizes sharp separation in cyclone separator。The present invention utilizes riser that pressed powder carries out strength diluted phase transport, and pressed powder transporting pattern is diluted phase transport, and pressed powder is fast in the flowing velocity of riser, enters separation equipment afterwards and realizes the sharp separation of delivery of carrier gas and solid powder material。The present invention utilizes riser that pressed powder is carried out strength diluted phase transport, pressed powder will not deposit, and transducer wall ' s abrasion is little, enters in cyclone separator afterwards and carries out sharp separation, can be applicable to various technique and realize solid powder material conveying, be a kind of well strength diluted phase transport method。
The present invention can be carried out various remodeling and change by those skilled in the art。Therefore, present invention covers the various remodeling in the scope falling into appending claims and equivalent thereof and change。
