The invention belongs to water treatment facilities technical field, be specifically related to a kind of condensate fine processor, the processing of the steam technique condensate water producing 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 technique condensate water, and accordingly, above mentioned condensate fine processor also can be described as condensate liquid polisher.Taking 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 products heating, steam is converted into condensate water after heat exchange, becomes liquid state from gaseous state.If using condensate water as discharge of wastewater, can cause so valuable water resource waste; Because this condensate water has been passed through desalting processing previously, once therefore discard, certainly can increase unreasonably water cost again; Also owing to being often 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; not only can saving water resource but also can protection of the environment; but; because the oil content in condensate water is about 1-200ml/L left and right; 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 condensate water preprocessor to condensate water pretreatment; and filter through active carbon filter; and after through the precision processing of condensate fine processor, be finally back to as boiler feedwater up to standard 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 being made up 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, in cylindrical shell, be provided with filter core, by filter core to impurity filterings such as the aforementioned greasy dirt in condensate water, hydrocarbon compound, iron oxide, and when condensate water was processed after 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.
