Description
Technical field
The present invention relates to a kind of cellulose composite membrane condensed-water recovering device, be applied to petrochemical complex, chemical industry water treatment, oil-removing iron-removing apparatus, condensate-water polishing.
Background technology
Current water of condensation results from steam in the process heated and carry, therefore it not only water quality is good but also containing amount of heat, along with development of modern industry, increasing industry notices that phlegma reclaims the economy and social value brought, but the phlegma recovery system of most industry, has high input, and locates inaccurate, in use unstable to Water-quality control, affect the practicality of its system.
Summary of the invention
Technical problem to be solved by this invention overcomes the deficiencies in the prior art, and provide a kind of cellulose composite membrane condensed-water recovering device, the technical solution adopted for the present invention to solve the technical problems is: structure of the present invention comprises condensate water collecting case, condensation water pot, condensate pump, to intake oily online monitoring system, compound film condensed water oil-removing iron-removing apparatus, accurate filter, water outlet oil online monitoring system, ion-exchanger, boiler user, discharge beyond standards collector, it is characterized in that condensate water collecting case is connected with condensation water pot, condensation water pot is connected with condensate pump, condensate pump is connected with the oily online monitoring system of water inlet, oily online monitoring system of intaking is connected with compound film condensed water oil-removing iron-removing apparatus, compound film condensed water oil-removing iron-removing apparatus is connected with accurate filter, accurate filter is connected with water outlet oil online monitoring system, water outlet oil online monitoring system is connected with ion-exchanger, ion-exchanger is connected with boiler user, water outlet oil online monitoring system is also connected with condensation water pot, oily online monitoring system of intaking also is connected with discharge beyond standards collector, and wherein compound film condensed water oil-removing iron-removing apparatus removes iron flask by compound film condensed water oil-removing, plastic film mulch case, entrance oil on-line detector, export oily on-line computing model, outlet iron on-line detector, keep pump, plastic film mulch pump, vent valve, differential pressure transmitter, plastic film mulch mother pipe, plastic film mulch circulation tube, wash water valve, backwash water pipe, compressed air line A, compressed air line B forms.
Technical process: first, the condensed water reclaimed is pooled in condensation water pot, condensed water oil-removing iron removal system is entered through condensate pump pressurization, the impurity such as oil, iron and suspended substance in water are removed successively by compound film condensed water oil-removing iron-removing apparatus and the accurate filter degree of depth, oil-contg in condensed water is down to below 0.3mg/L, iron level is down to 30 below μ g/L, then according to subsequent user to water quality requirement, select resin ion interchanger, precision processing is carried out to the condensed water reclaimed, the requirement of mesohigh boiler to water quality can be met.In said process, condensed water is after the degree of depth oil removing deironing process of compound film condensed water oil-removing iron-removing apparatus, accurate filter, after entering before continuous system, need the on-line monitoring being carried out in advance oil-contg by water outlet oil online monitoring system, the condensed water oil-contg guaranteeing to enter follow-up system is 100% qualified.When oil-contg is defective, condensed water returns by the pneumavalve of interlocking with the online oil meter of water outlet the water pot that condenses and again processes.Simultaneously, water outlet oil online monitoring system sends warning by the upper computer of PLC control system, PLC control system then automatically carries out the plastic film mulch of compound film condensed water oil-removing iron-removing apparatus stand-by facilities after alert, automatically carry out the operation that puts into operation immediately after plastic film mulch completes, then automatically carry out the stoppage in transit of disabling devices and quick-fried film backwash.In addition, in order to keep the operation of processing unit to have higher economy, condensed water, before entering condensed water oil-removing iron removal system, needs the on-line monitoring being carried out oil-contg in advance by the oily online monitoring system of water inlet.Under accidental state, the condensed water of oil-contg very high (> 20mg/L) is by directly entering sewer line with the water inlet online oil meter pneumavalve of interlocking, the Waste Water Treatment of Entry Firm processes, and does not enter condensed water oil-removing iron removal system and process.The normal condensed water of oil-contg (≤20mg/L) enters condensed water oil-removing iron removal system.
Compound film condensed water oil-removing iron-removing apparatus utilizes the bridging action of filtrate, pulverous filtration medium is covered on a kind of special porous pipe fitting (filter element), fine and close filter membrane is formed on its surface, when condensed water by manage outer entered in pipe by filter membrane and filter element hole time, by the comprehensive action of a series of means such as machinery obstruction and chemisorption, the impurity such as disposable removal oil wherein, iron and suspended substance.The filtrate that compound film condensed water oil-removing iron-removing apparatus is conventional has lignocellulose and Powdered Activated Carbon etc., and the different purposes according to device are selected flexibly, and does not carry out regeneration after using in a device and reuse.Filtrate does not carry out regeneration and reuses, that the technology of making based on the characteristic of the filtrate that at present both at home and abroad water treatment uses and filter core is considered completely, the secondary pollution that can prevent iron residual in reusable filtrate and filter core from producing condensed water, after also can avoiding using for some time, the processing power of equipment declines.The all devices of compound film condensed water oil-removing iron-removing apparatus is all assembled on a base, and have compact construction, advantage that floor space is little, above it, headroom is not less than 2.5 meters, so that install and maintenance.
The operation of compound film condensed water oil-removing iron-removing apparatus is mainly divided into three large steps: stone film forming, filtration are run and quick-fried film backwash.In quick-fried film backwash process, need the pressurized air of pressure 0.4 ~ 0.6MPa.Meanwhile, in order to prevent the filter element of apparatus main body equipment from being polluted, backwash water is designed to de-mineralized water.
The invention has the beneficial effects as follows, compound film condensed water oil-removing iron-removing apparatus of the present invention effectively can remove the impurity such as oil, iron, suspended substance in water once, does not increase the quantity of any kind ion simultaneously, high temperature resistant, level of automation is high and cost performance is high.These features are all that the device of other oil removing deironing and equipment are incomparable, are thus widely used in the industries such as petroleum and chemical industry at present.
