Abstract
The utility model discloses a cyclone enclosed centrifugal-separation duster. An air inlet of an air discharging pipe of the utility model is arranged above an air inlet. Consequently, a high-speed rotating cyclone is formed between severed dust and the air inlet of the air discharging pipe. The cyclone can seal severed dust under the entrance of the air discharging pipe effectively. Consequently, dust can not follow circulating air flow to enter the air discharging pipe. As a consequence, dust removal efficiency is raised largely.
Description
The utility model relates to a kind of equipment that solid dust is separated from gas, its outstanding feature is to prevent effectively that in separation process the dust that has separated from being brought in the blast pipe again.
At present, using the most general deduster is cyclone separator, is made up of air inlet pipe, blast pipe, cylindrical shell and storage bin hopper.After dust-contained airflow enters separator from air inlet pipe, in cylindrical shell, rotate, by centrifugal force dust is thrown to barrel, and downward along wall, fall into storage bin hopper.But because there is an airflow flowing upwards at the place, axle center of the exhaust outlet of deduster below, the dust that it will separate is rolled again, brings blast pipe into, so reduced the dust removal efficiency of deduster.
The purpose of this utility model provides a kind of deduster, it can not only be separated dust effectively from dusty gas, and in separation process, can prevent fundamentally that isolated dust from being brought in the blast pipe again, thereby improved the efficiency of dust collection of deduster widely.
The purpose of this utility model is achieved in that air inlet pipe is rectangle by air current flow direction and horizontal plane angle a, leads in the cylindrical shell with conical shell is tangent.The inlet of blast pipe extended upwardly the upper limb of air inlet pipe, and its trend is downwards passed storage bin hopper, and it is external to lead to deduster.Between cone and storage bin hopper, be provided with a cylindrical tube, a loam cake is arranged on the conic tube.The course of work of the present utility model is as follows: when dusty gas enters conical shell by air inlet at a high speed, form a high-speed screw air-flow and revolve in conical shell, solid dust is owing to be subjected to action of centrifugal force to be thrown to the taper barrel; Because barrel has tapering, it can give dust and downward power of gas of throwing to its wall again.Simultaneously spiral air flow also produces a downward component, make dust along wall to falling into storage bin hopper.The gas that has purified upwards screws in blast pipe and is drained.Between blast pipe inlet and storage bin hopper, there is a spiral air flow that rotates at a high speed to revolve.When deduster is worked, both made the dust that has separated in the storage bin hopper owing to gas circulation is taken up, only wear also that high velocity air revolves, the more impossible blast pipe that enters.
Owing to adopt such scheme, so efficiency of dust collection greatly improves, and simple in structure, resistance is again little.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the profilograph of first embodiment of the utility model.
Fig. 2 is the profilograph of second embodiment of the utility model.
Among the figure: 1, row's tube cell, 2, storage bin hopper, 3, blast pipe, 4, cylindrical tube, 5, reinforcement, 6, the air inlet square tube, 7, conic tube, 8, loam cake, 9, plug, 10, strengthen flat muscle.
In the embodiment shown in fig. 1, air inlet pipe (6) is pressed air flow direction, downwards and 10 ° of horizontal plane angles, and with tangent leading in the cylindrical shell of conic tube (7).At this, the channel cross-section of square air inlet pipe is of a size of: long by 300, all dimensional units in wide this specification of 75(are millimeter).The upper limb of air inlet is apart from the lower edge 90 of loam cake (8).The air intake of the blast pipe of internal diameter φ 150 (3) is apart from loam cake lower edge 45, and blast pipe trend downwards leads to outside the storage bin hopper (2).The vertex of a cone angle of cone (7) is 20 °, and big footpath is down, and little interior diameter is φ 300, and the cone height is 435, and with cylindrical tube (4) welding, the height of cylindrical tube is 300, and it welds with storage bin hopper (2) down.
In another embodiment shown in Figure 2, air inlet pipe (6) is pressed air flow direction, downwards and 10 ° of horizontal plane angles, and with tangent leading in the cylindrical shell of conic tube (7).The sectional dimension of square air inlet pipe also is 300 * 75.The upper limb of air inlet is apart from the lower edge 90 of loam cake (8).The air intake of the blast pipe of internal diameter φ 150 (3) is concordant with the loam cake lower edge.Apart from loam cake lower edge 45 places, one plug (9) is arranged, plug is hollow, but two will block, its length is 550, external diameter is identical with the blast pipe external diameter, and it is upper and lower to have reinforcement (10) with (5) it to be linked to each other with cylindrical shell respectively, identical among the size of conic tube (7) and cylindrical tube (4) and the last embodiment.Weldering one conic tube storage bin hopper (2) below the cylindrical tube.Its cone-apex angle is 60 °.
Claims (4)
1, a kind of deduster of being made up of air inlet pipe, conic tube, cylindrical tube, blast pipe, storage bin hopper, it is characterized in that: the air intake of blast pipe is located at the top of air inlet upper limb.
2, deduster according to claim 1 is characterized in that: blast pipe leads to outside the body from top to bottom.
3, deduster according to claim 1 is characterized in that: the lower edge of the air intake of blast pipe is concordant with the lower edge of loam cake, and blast pipe leads to outside the body from bottom to top, and below the air intake of blast pipe a plug is set vertically.
4, deduster according to claim 1 is characterized in that: conic tube is located at the air inlet place, and big footpath is following.
