Abstract
The utility model discloses a cyclone desander with a central air guide pipe, belonging to a solid-liquid separator and being an improved hydrocyclone desander researched aiming at high-efficient desanding on rivers with higher sand content or other water sources. The cyclone desander with the central air guide pipe comprises a cavity, a feed pipe, an overflow pipe and a bottom flow pipe, wherein the cavity consists of a cylindrical cavity at the upper section, a large conical cavity at the middle section and a small conical cavity at the lower section; the feed pipe is connected in from the side wall of the cylindrical cavity of the upper section, the bottom of the small conical cavity at the lower section is connected with the bottom flow pipe, and the overflow pipe is upwards connected out from the center of the cylindrical cavity at the upper section; the central air guide pipe is additionally arranged at the central axis position of the cyclone desander, the lower end of the central air guide pipe is opened and arranged between the upper edge of the bottom flow pipe and the lower edge of the overflowing pipe, the upper end of the central air guide pipe penetrates through the overflow pipe, and a central air column sucked in by the cyclone desander is outwards led out. By arranging the air guide pipe, the processing capacity of the cyclone desander can be improved by about 30% compared with the existing universal cyclone desander, and the energy consumption can be reduced by about 20%.
Description
Technical field
The utility model hydrocyclone belongs to a kind of equipment for separating liquid from solid, and particularly a kind of separatory high desanding efficiency of fine grained that is applicable to reaches the hydrocyclone than low energy consumption and underflow productive rate.
Background technology
To be a kind of effect that utilizes pressure be converted into the device that rotatablely moves with the rectilinear motion of fluid to hydrocyclone desander, relies on centrifugal sedimentation to separate.But its inside does not have moving component, little, the easy for installation continued operation of floor space, safeguards simply, is used as the desirable water treatment facilities of desanding in the water source heat pump system.
When containing the higher source water of fine husky amount and select hydrocyclone, adopt minor diameter, small-angle hydrocyclone usually, there is research to adopt the form of bipyramid section to improve the removal efficient of fine sediment.The minor diameter hydrocyclone has removal effect preferably to fine sediment, but its operating pressure is also relatively large, and energy loss is higher.
Air column is a kind of endemism in the work of Separation of Solid and Liquid hydrocyclone, and the cyclone that every underflow opening opens wide all air column will occur in operate as normal.The existence of air column causes containing in the overflow water outlet a large amount of air, after such overflow that has a large amount of air enters water source heat pump units, can reduce the heat transference efficiency of source pump, influences the whole energy index of water source heat pump system.
Studies show that any separation process does not take place in air column inside, the energy of its internal consumption only is used to keep the existence of air column, the work of hydrocyclone is not played the direct effect in any front.But the energy of air column internal consumption accounts for about half of the whole internal losses of cyclone.The later cyclone of cancellation air column can change the distribution of internal energy, improves the outlet pressure of overflow, and reduces the internal pressure loss.
The scientific research personnel is mainly from preventing that underflow from sucking air and setting about in the research in the past, often adopts the sealing underflow or connect method such as sufficiently long pipeline on underflow opening, and these modes all can not adopt in actual production owing to destroyed cyclone normal separation process.Even adopt,, then be difficult to avoid fully the appearance of air column equally if contain the gas of q.s in the charging of cyclone.The mode that present stage offsets except that air column in the waterpower cyclone mainly contains solid bar and center insertion parts structure (particularly center fin) etc.These two kinds of structures can effectively reduce the operation energy consumption of hydrocyclone, improve separative efficiency, but the solid rod in center has occupied the inner space of hydrocyclone, causes disposal ability to reduce; The center fin places desander inside, is not suitable for the equipment application of desander.
Summary of the invention
The utility model provides a kind of improved hydrocyclone at the deficiencies in the prior art, to reduce operation energy consumption, improves disposal ability.
The technical solution of the utility model is:
The hydrocyclone of a kind of center band air conduit, it comprises cavity, feed pipe, overflow pipe and underflow pipe, described cavity is made up of the cylindrical cavity of epimere, the big circular cone cavity in stage casing and the conicle cavity of hypomere, described feed pipe is tangentially inserted by the sidewall of the cylindrical cavity of epimere, the bottom of the conicle cavity of hypomere connects underflow pipe, and overflow pipe then upwards picks out from the center of the cylindrical cavity of epimere;
It is characterized in that: set up a center air conduit in the central axis position of hydrocyclone cavity, described center air conduit lower ending opening and be arranged at the underflow pipe upper limb and the overflow pipe lower edge between, overflow pipe is passed in its upper end, outwards derives the center air column that hydrocyclone sucks.
Also be connected to one section overflow delivery line on described overflow pipe, the center air conduit is a hollow circular tube, and the bottom can be regulated apart from the distance of underflow pipe upper limb.
The utility model has following advantage:
1. this hydrocyclone adopts the center air conduit to occupy the position of air column, has destroyed the formation of air column, and air is derived by the center air conduit, and is capable of reducing energy consumption about 20%, and the disposal ability of hydrocyclone can improve about 30%;
2. the center air conduit lower edge of hydrocyclone can be regulated apart from the distance of underflow pipe top edge, helps regulating the different service condition of operating condition adaptation of hydrocyclone;
3. for the surface water water source heat pump system, can suck air when using general hydrocyclone, thereby change the fluid state of water inlet, this hydrocyclone is derived the intermediate air post by employing center air conduit, so can avoid the fluid after the hydrocyclone to become solid, liquid, gas three-phase stream, keep the water source heat pump units water inlet and be essentially solid, liquid two-phase stream, thereby do not reduce the heat transfer property of fluid, significant for the operation of surface water water source heat pump system.
This structure is specially at the higher source water of fine husky content.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
In conjunction with the accompanying drawings, but protection domain of the present utility model is not limited to accompanying drawing and following specific embodiment.
As shown in Figure 1, this hydrocyclone comprises cavity, feed pipe 1, overflow pipe 8 and underflow pipe 7.Wherein cavity is made up of the cylindrical cavity 4 of epimere, the big circular cone cavity 5 in stage casing and the conicle cavity 6 of hypomere.Feed pipe 1 is tangentially inserted by the sidewall of the cylindrical cavity 4 of epimere, and the bottom of the conicle cavity 7 of hypomere connects underflow pipe 7, and 8 centers from the cylindrical cavity 4 of epimere of overflow pipe upwards pick out.More than for having the cyclone of common structure now.The improvement of this structure is to have increased center air conduit 3, it is a hollow circular tube, its lower ending opening is connected with this hydrocyclone inner fluid, and be arranged between the lower end of the upper end of underflow pipe 7 and overflow pipe 2, the upper end of center air conduit 3 is passed from overflow pipe 2, and the tube wall of the overflow pipe fairlead 8 that connects from overflow pipe 2 upper ends outwards passes, and outwards derives the center air column that hydrocyclone sucks.
