Technical field

The invention belongs to the water treatment facilities technical field, be specifically related to a kind of condensate fine processor, the processing of the steam technique condensate water produced for the industry to such as petrochemical industry, oil refining industry, biology,drug and chemical industry industry, power station and papermaking.

Background technology

Above mentioned condensate water also claims condensate liquid or surface condensate and even is called the technique condensate water, and accordingly, above mentioned condensate fine processor also can be described as the condensate liquid polisher.Take chemical industry and oil refining industry as example, need in process of production to use in large quantities high-temperature steam as the energy to various oil product heating, steam is converted into condensate water after heat exchange, from gaseous state, becomes liquid state.If using condensate water as discharge of wastewater, can cause valuable water resource waste so; Passed through again desalting processing before due to this condensate water, once therefore discarded, certainly can increase unreasonably the water cost; Also owing to often being attended by micro-hydrocarbons and wet goods etc. in condensate water, therefore directly discharge can undermine environment, and if qualified discharge after treatment, although can avoid affecting environment, cost of water treatment is higher.Condensate water is used as boiler feedwater; but but not only saving water resource but also protection of the environment; but; due to the oil content in condensate water about about 1-200ml/L; contain oil standard higher than boiler feedwater far away; thereby can not be using condensate water directly as boiler feedwater, otherwise the working life of boiler can be seriously undermined, and the purity of the steam that boiler produces can be had a strong impact on.

Utilize the condensate water preprocessor to the condensate water pretreatment; and filter through active carbon filter; and, by the precision processing of condensate fine processor, finally as boiler feedwater up to standard, be back to that boiler can be received saving water resource, protection of the environment, the effect of the many carvings of an arrow that reduce production costs.Because can be by the hydrocarbons in condensate water the impurity filterings such as hydrocarbon compound (alkane, cycloalkane, alkene, alkynes and aromatic hydrocarbon), oil, iron oxide after pretreatment, activated carbon filtration and precision processing.The complete treatment system consisted of condensate water preprocessor, active carbon filter and condensate fine processor is called condensate polishing system, can refer to " process condensed water processing system (this patent is proposed by the applicant) " that Chinese invention patent Granted publication CN102091480B recommends to this.

No matter be condensate water preprocessor or condensate fine processor, be provided with filter core in cylindrical shell, by filter core to impurity filterings such as the aforementioned greasy dirt in condensate water, hydrocarbon compound, iron oxide, and after condensate water is processed to a period of time, the cause of being stopped up due to filter core, the pressure reduction of condensate water turnover cylindrical shell increases, when reaching while being about 0.15MPa, pressure reduction need to carry out backwash to filter core, to reduce pressure reduction, that is to say and make pressure reduction be restored to normal pressure difference, to ensure filter efficiency and the filter effect to condensate water.

Water consumption while in order to reduce, the filter core in the cylindrical shell of condensate fine processor being implemented to backwash and guarantee backwash effect, therefore, usually the condensate fine processor is equipped with to a backwash mechanism, " filter " (this patent is proposed by the applicant) confirmation that the condensate fine processor of this structure can be provided by invention patent mandate notification number CN100488594C.

The technical scheme that aforementioned CN100488594C provides is owing to being separated out one group of backwash synergy chamber independently separately on the cylindrical shell dividing plate, so when implementing backwash, become and concentrate on certain backwash synergy chamber originally sharing counter-flushing liquid in whole cylindrical shell epicoele equally, flow velocity in unit interval is doubled, for example, when backwash synergy chamber is separated into eight independently zones or while claiming chamber, flow velocity in unit interval has increased octuple so, the counter-flushing liquid of originally sharing eight zones concentrates on a zone, thereby be able to the mistake filter core corresponding to this below, zone effectively clean, made filter core obtain the service life (specifically can refer to the 7th page of the 2nd section explanation to the 8th page of the 6th row of specification of this patent) of desirable backwash cleaning effect and prolongation filter core, water consumption in the time of can saving backwash simultaneously.

Yet, there is following shortcoming in the backwash mechanism that above-mentioned " filter " is equipped with: one, because the counter-flushing liquid that goes out the self counter flushing liquid outlet was ejected into certain chamber of backwash synergy chamber before this to be tending towards level, then by chamber, make counter-flushing liquid implement backwash in the mode of trickling to the filter core that is positioned at the chamber below downwards, thereby the backwash liquid outlet can not directly be aimed at filter core performance backwash effect, that is to say because counter-flushing liquid does not produce direct jet-action to filter core, so cleaning performance shortcoming to the dirt that attaches on filter core, scavenging period is grown and is wasted water source and affect the time that filter recovers the initialization state, its two, because backwashing time is long, thereby be unfavorable for save supporting the power consumption of the motor of backwash mechanism work, they are three years old, the structure relative complex of backwash synergy chamber, for example need on the dividing plate of cylinder chamber, with the interval state, one component dividing plate be set, organize the demarcation strip distributed radially and form a plurality of backwash synergy chamber by means of the sealing of cover plate on the dividing plate of cylinder chamber by this, therefore not only make trouble, and raw-material use amount is large.

When normal operation, be in the process of the present invention in the condensate water processing to awaiting precision processing, close the valve on the pipeline of blowdown interface 41 of condensate water inlet tube 4, open the valve on the pipeline matched with inlet tube water inlet 42, the condensate water that awaits precision processing just enters in cylindrical shell cavity of resorption 14 from condensate water inlet tube 4, for the one group of cavity of resorption filter core 3 in cylindrical shell cavity of resorption 14, filters.Water after filtration enters in cylindrical shell epicoele 13 from cavity of resorption filter core liquid outlet 31, the water entered in cylindrical shell epicoele 13 enters in spacer cylinder chamber 51 through check valve 521 and spacer cylinder water inlet interface 52 successively, because an end of return pipe 6 communicates with spacer cylinder chamber 51, therefore by the water outlet mouthpiece 63 of return pipe 6, drawn and the water used as boiler feedwater.In this process, compressed air is introduced interface 61, positive flushing water water inlet interface 62 and backwashing water and is introduced interface 64 all in closed condition.

When condensate fine processor of the present invention after operation a period of time, when the pressure reduction between condensate water inlet tube 4 and return pipe 6 reaches settings and for example reaches 0.15MPa, so by pressure difference transmitter by signal feedback to electric control box, enter backwashing procedures.Preferred scheme can arrange Pressure gauge (specifically can referring to patent of invention publication No. CN103301682A) on the pipeline of return pipe 6.

Backwashing procedures has two kinds of control modes, the one, automatic control, adopt programmable controller (PLC) to control, during backwash according to the signal of pressure difference transmitter by PLC switching controls valve and order about backwash motor 71 work of backwash tube driving mechanism 7, drive backwash reductor 72 by backwash motor 71 under this state, drive main shaft 75 rotations by backwash speed reducer output shaft 721 through shaft coupling 73 under the state slowed down at backwash reductor 72, because the signal panels 76 that are nested with on main shaft 75 are fixedly connected with the lower shaft coupling 732 of shaft coupling 73 by the adjustment tank attachment screw 7621 on adjustment tank 762, therefore when driving main shaft 75 rotations, shaft coupling 73 drives signal panels 76 rotations, telltale hole 761 on signal panels 76 is during corresponding to signal picker 772, by signal picker 772 by signal feedback to PLC, sending signal by PLC temporarily quits work backwash motor 71, dwell time is arranged by PLC, be generally several seconds kinds 5-10 seconds for example.In this process, introduce interface 64 by backwashing water backwashing water is introduced to return pipe 6, due to check valve 521 now in closed condition, therefore the water entered in return pipe 6 enters in the spacer cylinder chamber 51 of spacer cylinder 5, the upper end that leads to liquid joint 83 due to backwash tube is positioned at spacer cylinder chamber 51, and because the fluid-through tube joint liquid-through hole 831 on the wall body of the logical liquid joint 83 of backwash tube communicates with spacer cylinder chamber 51, so the fluid-through tube joint liquid-through hole 831 of the water in spacer cylinder chamber 51 on the logical liquid joint 83 of backwash tube introduced in logical liquid joint.Again because logical liquid joint communicates with the backwash tube chamber of backwash tube 8, also because counter-flushing liquid spray arm 82 communicates with the backwash tube liquid outlet 81 of backwash tube 8 lower ends, therefore introduce the backwashing water of interface 64 introducings successively through return pipe 6 through backwashing water, spacer cylinder chamber 51, fluid-through tube joint liquid-through hole 831, the backwash tube liquid outlet 81 of backwash tube 8 enters the counter-flushing liquid spray arm chamber 822 of counter-flushing liquid spray arm 82, until be injected into cavity of resorption filter core liquid outlet 31 by the spray arm opening 821 communicated with counter-flushing liquid spray arm chamber 822, cavity of resorption filter core 3 that be connected with cavity of resorption filter core liquid outlet mating holes 21 and that be positioned at cylindrical shell cavity of resorption 14 is implemented to backwashes.When the time of setting, arrive, PLC sends instruction so, make backwash motor 71 task again, until make next signal hole 761 on signal panels 76 corresponding to signal picker 772, so repeat and until make counter-flushing liquid spray arm 82 backwash tube 8 with 360 ° of state revolutions at intermittence process in all cavity of resorption filter cores 3 are implemented to backwashes.After backwash finishes, more just rinsing, then turning back to the aforesaid state that former water processed the condensate water that awaits precision processing.The 2nd, manual control, on cylindrical shell 1 or follow in cylindrical shell 1 place electric control box is set, switch valve when pressure reduction reaches setting value, and start 71 work of backwash motor, by the superincumbent description of applicant, until counter-flushing liquid spray arm 82 completes the backwash to the cavity of resorption filter core 3 in cylindrical shell cavity of resorption 14 around cylinder chamber demarcation strip 2 one circles (360 °).

After with automated manner or with manual mode, having completed backwash, enter positive rinsing step, just rinsing is mainly the impurity of bringing in backwashing water and gas while rinsing out backwash.While just rinsing, valve opening on the pipeline be connected with the inlet tube water inlet 42 of condensate water inlet tube 4, and the valve closing on blowdown interface 41, water outlet mouthpiece 63 on the pipeline of return pipe 6, compressed air introduce interface 61 and backwashing water is introduced interface 64 all in closed condition, and positive flushing water water inlet interface 62 rinses rear condensate fine processor of the present invention and enters again the state of coming into operation in opening.

In cavity of resorption filter core 3 is carried out to the process of backwash, the valve closing on the passage of the inlet tube water inlet 42 of condensate water inlet tube 4,41 unlatchings of blowdown interface; Valve opening on the passage that the backwashing water introducing interface 64 of return pipe 6 and compressed air are introduced interface 61 (be take and enabled compressed air as example simultaneously, if do not enable, the closes compression air is introduced the valve on the pipeline of interface 61 so), the valve closing on the passage of water outlet mouthpiece 63, positive flushing water water inlet interface 62.

By the explanation above-mentioned to the applicant, can know that the backwash effect to cavity of resorption filter core 3 that the present invention shows should be ultimate attainment fully.

In sum, technical scheme provided by the invention has overcome the shortcoming in the prior art, has completed the invention task, has cashed the technique effect referred in the superincumbent technique effect of applicant hurdle.
