Description
Technical field
The utility model relates to a kind of thermal power generation flue gas desulphurization system sewage treatment equipment that is used for, and relates to a kind of hydrocyclone underflow case with many interfaces particularly.
Background technology
Hydrocyclone is the equipment that makes the main application that contains the separation of stereoplasm solid and liquid, is widely used in the Coal,steam plant with FGD apparatus system at present, is mainly used in lime stone pulping system, gypsum dehydration system and Waste Water Treatment.Hydrocyclone is made up of inlet collection case distributor, eddy flow, spill box, underflow case etc.The slurries that enter are handled through eddy flow and are divided into overflow (solid content is lower) and underflow (solid content is higher) two parts, and overflow slurry collects in the cyclone spill box and discharges, and the underflow slurries collect in cyclone underflow case by desilting tip and discharge.In the flue gas desulfur device system, hydrocyclone underflow slurries have a flow direction usually incessantly, can be sent to different equipment handles again, because slurry medium has the characteristics of wearing and tearing, corrosion and easily deposits, pipeline that requirement connects and equipment need be considered anticorrosion and wear-resisting, and pipeline should guarantee certain gradient and should avoid the appearance of dead end.
For example, in gypsum dehydration system, the two cyclones underflow is delivered to two corresponding vacuum belt dewaterers respectively and is handled, and requirement simultaneously can be standby each other.At this moment, cyclone underflow case has only an interface.
Scheme one, usually the way of taking is that a distributor box that has executing agency is set below every cyclone, distributor box is provided with two outlets can be connected to two vacuum belt dewaterers respectively, drive cyclone underflow case outlet conduit by executing agency, make underflow flow to two outlets respectively, as shown in Figure 1.
Scheme two is provided with the flow direction that valve distributes the underflow slurries at underflow case outlet conduit to fall the threeway of " Y " type, as shown in Figure 2.
All there is shortcoming in above-mentioned two schemes:
For scheme one, a distributor box that has executing agency is set below every cyclone, distributor box is provided with two outlets and is connected to two vacuum belt dewaterers respectively.Following shortcoming is arranged:
A, increase equipment investment
Increased equipment (distributor box), because slurry medium has the effect of wearing and tearing, corrosion, distributor box need take the abrasionproof anti-corrosion measure to handle especially, adopt chamber interior wall lining rubber usually or be coated with the mode of anticorrosion scale, behind the line with rubber or the casing that is coated with behind the anticorrosion scale do not allow to carry out again welding job.
B, need arrangement space
Normally gravity flow effect of the charging of distributor box and discharging so need be arranged between cyclone and the vacuum belt dewaterer, is arranged up and down, guarantees the gravity flow effect with difference in height.Casing itself has certain volume, also needs arrangement space.So be to build on the floor height or all needing the space on the construction area, increasing building cost.
C, additional rinse-system
Slurry medium has certain solid content, especially the concentration of underflow slurries is higher, can reach 50%, the pipeline of pumped (conveying) medium has also increased in the time of increase equipment, increase slurry medium possibility of jamming on equipment that connects and pipeline, needed extra rinse-system and the pipeline of increasing to be used for operating obstruction mediation.
For scheme two, to fall the threeway of " Y " type the flow direction that valve distributes the underflow slurries is set at underflow case outlet conduit.Following shortcoming is arranged:
A, increase pipe fitting (threeway of " Y " type)
B, erosion corrosion
" Y " type threeway node place is often washed away by the shunting of medium underflow slurries, and it is broken that liner rubber is easy to be contained the wearing and tearing of stereoplasm liquid, has also increased the possibility of slurries deposition herein when having increased the pipeline internal medium flow resistance; Slurries contact steel pipe fittings with corrosion property can make pipe fitting leak.Therefore, because the acting in conjunction of wearing and tearing and corrosion, the threeway of " Y " type very easily damages.
C, deposition are stopped up
Slurry medium has certain solid content, and especially the concentration of underflow slurries is higher, can reach 50%, and when valve closing, the slurries deposition is blocked in threeway place of " Y " type, difficulty when causing once more Open valve, and the flushing cleaning is difficulty also.
The utility model content
The purpose of this utility model is at the problems referred to above, provides a kind of simple in structure, uses pipe fitting few, and it is little to take up room, and is difficult for stopping up, and cleans easily the hydrocyclone underflow case with many interfaces.
For achieving the above object, the utility model adopts following technical scheme:
A kind of hydrocyclone underflow case with many interfaces, this underflow case has the bottom surface of inclination, on the sidewall of underflow case, be provided with at least two underflow outlets near the bottom surface lower, each underflow outlet is provided with valve, the angle [alpha] that described bottom surface tilts is 5 °～25 °, and described underflow outlet diameter is 20～1400mm.
The angle [alpha] that described bottom surface tilts is 15 °
The outlet of described underflow is two, and the angle β between two underflow outlet axis is 20 °～120 °.
Described underflow export volume is three, and the angle β between each underflow outlet is 20 °～60 °.
Described underflow export volume is four, and the angle β between each underflow outlet is 20 °～40 °.
Be provided with bearing rib in the underflow box top, between each gusset, be provided with cover plate.
Owing to keep certain gradient underflow to be difficult for precipitation in the bottom of underflow case, the underflow case of many interfaces, move more flexible, the reliability height.The various flows can control the underflow slurries is easily opened or opened respectively to a plurality of outlet valves simultaneously to, the purpose of avoiding the mode by increase equipment and pipeline just can reach, also reduced the blockage problem of underflow slurries.Be installed in cyclone underflow case underflow exit valve if clogging can the pipeline before the valve be washed by opening the underflow cover plate, very convenient.Its occupation space simple in structure of underflow case of the present utility model is also smaller.Can be widely used in the many aspects of modern industry, as solid-liquid separation systems such as electric power, metallurgy, mines.
