Description

A kind of cyclone separator

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 the steam, imitate along with steam together enters next, so not only caused the pollution of steam condensate (SC) to cause the COD value higher, and organic matter also is attached to evaporimeter inside easily, influence the heat exchange effect, simultaneously equipment is also caused certain corrosion.

So-called COD (COD) is under certain conditions, when adopting certain strong oxidizer to handle water sample, and the oxidant content that consumes.The COD value is more little, shows that water pollution is more light.It is what a index of reducing substances in the expression water.Reducing substances in the 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 the water.Organic matter is very big to the harm of industrial water system.Contain a large amount of organic water meeting contaminated ion exchanger resin by desalting system the time, pollute anion exchange resin especially easily, the resins exchange ability is reduced.Sometimes organic matter also may be brought in vapour system and the 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, it is more and more important to seem, and the evaporation and concentration industry is also more and more higher to the evaporation requirements in water quality.

Summary of the invention

The purpose of present technique provides a kind of can the liquid in the liquid-vapor mixture effectively the separation, prevents the cyclone separator that liquid comes out from venthole along with gas.

This cyclone separator comprises cylindrical shell, is positioned at end socket on the cylindrical shell, opens the venthole on end socket, is provided with a baffle plate in the end socket of venthole bottom, and baffle plate is the part of sphere, and central part is to venthole direction projection, and the baffle plate periphery has sawtooth; The peripheral dimension of baffle plate is greater than venthole, and baffle plate and end socket inwall are gapped; At the end socket inwall slash pendular ring is arranged fixedly, baffle plate is positioned at casts aside pendular ring inside.

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 owing to be subjected to action of centrifugal force.Remain a small part liquid-vapor mixture and continue to rise, be subjected to stopping of baffle plate, stoped drop to continue to move upward, gas then passes through from the gap between baffle plate and the end socket, flows out through venthole again, has realized vapor-liquid separation.Baffle plate is umbrella shape, and central part like this, after the heavier drop in cylindrical shell middle part is run into baffle plate, can accumulate in the inner concave of baffle plate to venthole direction projection, and mobile to the baffle plate periphery gradually.The zigzag periphery makes that drop is easier to drip from periphery.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, casts aside the pendular ring group and has ended the drop on the cylinder inboard wall and enter venthole and arrange.

Described cyclone separator, the diameter of described ball equals barrel diameter.

Described cyclone separator, the baffle plate neighboring is rounded, and the diameter of baffle plate neighboring is bigger than venthole diameter.The baffle plate neighboring is rounded, can set out the steam ports bottom easily, and coaxial with venthole, and is better to the blocking effect of drop.The diameter of baffle plate neighboring is than the big 300-400mm of venthole diameter.

Described cyclone separator is cast aside the pendular ring internal diameter than the little 140-160mm of cylinder internal diameter.

Described cyclone separator, baffle edge are to the distance h 〉=D1/4 of end socket inwall on the tubular axis direction, and D1 is the diameter of venthole.Like this, vapor-liquid separation better effects if, efficient are higher.

Description of drawings

Fig. 1 is the schematical top view of cyclone separator.

Fig. 2 is the local enlarged diagram of baffle plate.

The specific embodiment

Referring to the cyclone separator of 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.

At the end socket inwall slash pendular ring 5 coaxial with cylindrical shell arranged fixedly, baffle plate is positioned at casts aside pendular ring inside.

Baffle plate 2, support column 4, slash pendular ring 5 three big functional parts are formed the vapor-liquid separation parts.Baffle arrangement is similar to umbrella top shape, and outer circular edge is zigzag fashion.

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 subjected to stopping of baffle plate, steam is forced to change by rising on the gap between baffle plate and the separator inwall, and steam is owing to stopped, speed descends to some extent, and droplets entrained is dripped by baffle edge sawtooth place under the gravity effect in the steam.The diameter D2 that the experiment proved that baffle plate must could effectively stop steam directly to be discharged from venthole, i.e. D2=D1+(300-400 than the big 300-400mm of separator venthole diameter D1) mm.Baffle plate radian L size is general identical with separator cylindrical shell diameter D, and the general 5mm of its thickness is advisable.

The effect of support column 4 has two aspects, play the effect of fixing and supporting baffle on the one hand, general quantity is about 4, and the effect of control steam flow rate is played in the variation of length (equaling baffle edge substantially 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 the support column, its sectional area can be similar to thinks V ₁=π * D1*h, the sectional area of steam gas outlet are V ₂=π * D1* D1/4, V ₁〉=V _2,Just can guarantee the higher vapor-liquid separation efficiency of ratio of steam, so the length h palpus 〉=D1/4 of support column.

Cast aside arranging of pendular ring 5 and can be conducive to dripping of entrained drip in the steam more, it is parallel with the separator cartridge body wall to cast aside pendular ring, and vertically downward, the resistance in the time of can reducing drop and drip makes that drop is easier to drip.The distance of casting aside pendular ring and separator inwall keeps the 70-80mm spacing, namely cast aside pendular ring inner diameter D 3=cylinder internal diameter D-(140-160) mm, the slash pendular ring is generally about 60mm 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 the 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 practical sense.
