Description
Technical field
Present technique relates to cyclone separator, specifically, is a kind of cyclone separator that liquid-vapor mixture is separated that uses in sugar alcohol industry vapo(u)rization system.
Background technology
In sugar alcohol industry vapo(u)rization system, liquid-vapor mixture enters into separator, if the separator separating effect is not good, to there be large amount of organic to be entrained in steam, along with steam together enters next effect, so not only caused the pollution of steam condensate (SC) to cause the COD value higher, and organic matter also easily is attached to evaporimeter inside, affect heat transfer effect, simultaneously equipment is also caused certain corrosion.
So-called COD (COD) is under certain conditions, when adopting certain strong oxidizer to process water sample, and the oxidant content that consumes.The COD value is less, shows that water pollution is lighter.It means what a index of reducing substances in water.Reducing substances in water has various organic matters, nitrite, sulfide, ferrous salt etc.But main is organic matter.Therefore, COD (COD) is again often as weighing what index of organic matter content in water.Organic matter is very large to the harm of industrial water system.Contain a large amount of organic water meeting contaminated ion exchanger resin by desalting system the time, especially easily pollute anion exchange resin, the resins exchange ability is reduced.Sometimes organic matter also may be brought in vapour system and condensate water, and pH is reduced, and causes system's corrosion.Along with the pay attention to day by day of China to fwaater resources protection, the qualified discharge of sewage seems more and more important, and the evaporation and concentration industry is also more and more higher to the requirement of evaporation water quality.
Summary of the invention
The purpose of present technique is to provide a kind of can the liquid in liquid-vapor mixture effectively the separation, prevent liquid along with gas from the venthole cyclone separator that liquid-vapor mixture is separated out.
The cyclone separator that this separates liquid-vapor mixture, comprise cylindrical shell, be positioned at end socket on cylindrical shell, open the venthole on end socket, be provided with a baffle plate in the end socket of venthole bottom, baffle plate is the part of sphere, central part is to venthole direction projection, and the baffle plate periphery has sawtooth.The baffle plate neighboring is rounded, and the diameter of baffle plate neighboring is larger than D1; Baffle plate and end socket inwall are gapped; Be fixed with the slash pendular ring on the end socket inwall, it is inner that baffle plate is positioned at the slash pendular ring; Baffle edge is to the distance h 〉=D1/4 of end socket inwall on the tubular axis direction, and D1 is the diameter of venthole.
The beneficial effect of present technique: liquid-vapor mixture enters cyclone separator, and rotation is risen in cylindrical shell.Overwhelming majority drop is thrown toward cylinder inboard wall due to the effect that is subject to centrifugal force.Remain a small part liquid-vapor mixture and continue to rise, be subject to stopping of baffle plate, stoped drop to continue to move upward, gas passes through from the gap between baffle plate and end socket, then flows out through venthole, has realized vapor-liquid separation.Baffle plate is umbrella shape, and central part is to venthole direction projection, and the baffle plate periphery has sawtooth.Like this, after the heavier drop in cylindrical shell middle part is encountered baffle plate, can be gathered in the inner concave of baffle plate, and mobile to the baffle plate periphery gradually.Zigzag periphery makes that drop is easier to drip from periphery.The baffle plate neighboring is rounded, can set out easily the steam ports bottom, and coaxial with venthole, and is better to the blocking effect of drop.Generally also can adhere to some drops on cylinder inboard wall, drop also can be along with air-flow be discharged through venthole under the drive of air-flow like this, skims the pendular ring group and has stopped the drop on the cylinder inboard wall and enter venthole and arrange.Baffle edge is to the distance h 〉=D1/4 of end socket inwall on the tubular axis direction, and vapor-liquid separation better effects if, efficient are higher.
The described cyclone separator that liquid-vapor mixture is separated, the diameter of best described ball equals barrel diameter.
The described cyclone separator that liquid-vapor mixture is separated, the diameter of baffle plate neighboring is than the large 300-400mm of venthole diameter.
The described cyclone separator that liquid-vapor mixture is separated is skimmed the pendular ring internal diameter than the little 140-160mm of cylinder internal diameter.
Description of drawings
Fig. 1 is the schematical top view of cyclone separator that liquid-vapor mixture is separated.
Fig. 2 is the local enlarged diagram of baffle plate.
The specific embodiment
The cyclone separator that liquid-vapor mixture is separated referring to Fig. 1, comprise cylindrical shell 6, be positioned at cylindrical shell top end socket 1, open the venthole 3 on end socket, be provided with a baffle plate 2 in the end socket of venthole bottom, baffle plate is fixed on the end socket inwall by four support columns 4.The peripheral dimension D2 of baffle plate is greater than the diameter D1 of venthole, and baffle plate and end socket inwall are gapped.Have the import tangent with cylinder inboard wall (belonging to prior art, not shown) at the bottom of cylindrical shell barrel.
Baffle plate is umbrella shape, and central part is to venthole direction projection, baffle plate periphery indention (referring to Fig. 2).Baffle edge is to the distance h 〉=D1/4 of end socket inwall on the tubular axis direction.
Be fixed with the slash pendular ring 5 coaxial with cylindrical shell on the end socket inwall, it is inner that baffle plate is positioned at the slash pendular ring.
The effect of baffle plate 2 is to stop steam directly directly to discharge from separator venthole 3, the structural design of its umbrella top type, when steam from bottom to top moves, when rising to the baffle plate present position, be subject to stopping of baffle plate, steam is forced to change by rising on the gap between baffle plate and separator inwall, and steam is owing to being stopped, speed descends to some extent, and the drop of carrying secretly in steam is dripped by baffle edge sawtooth place under Action of Gravity Field.The diameter D2 that the experiment proved that baffle plate must than the large 300-400mm of separator venthole diameter D1, could effectively stop steam directly to be discharged from venthole, i.e. D2=D1+(300-400) mm.Baffle plate radian L size is general identical with Membrane Separator Cylinder for CFB Boiler diameter D, and the general 5mm of its thickness is advisable.
The effect of support column 4 has two aspects, play on the one hand the effect of fixing and supporting baffle, general quantity is 4 left and right, and the effect of controlling steam flow rate is played in the variation of length (substantially equaling baffle edge to the distance of end socket inwall on the tubular axis direction) h by support column on the other hand.Form an approximate cylindrical space between end socket 1 inwall of separator and baffle plate top and support column, its sectional area can be similar to thinks V
1=π * D1*h, the sectional area of steam gas outlet is V
2=π * D1* D1/4, V
1〉=V
2,Just can guarantee the higher vapor-liquid separation efficiency of steam, so the length h palpus 〉=D1/4 of support column.
Skim arranging of pendular ring 5 and can more be conducive to dripping of entrained drip in steam, skim pendular ring parallel with the separator cartridge body wall, vertically downward, the resistance in the time of can reducing drop and drip more easily drips drop.The distance of skimming pendular ring and separator inwall keeps the 70-80mm spacing, namely skim pendular ring inner diameter D 3=cylinder internal diameter D-(140-160) mm, the slash pendular ring is generally the 60mm left and right along the length of cylindrical shell axial direction, and can be according to the size of quantity of steam, suitably adjust length, thickness is generally 5mm.
Vapor-liquid separating device is positioned at the end socket position of cyclone separator, flow in order to control indirect steam, improve vapor-liquid separation efficiency, effectively reduce COD (COD) value in condensed water, it is to the loss of material, the raising that reduce evaporating concentration process and improve evaporating and concentrating process, reduce water pollution etc. important realistic meaning.
