The filter packing that is provided with in the said grade one filter tank body is nylon 66 base material fillers, can high temperature resistant and high efficiency filter; The mesh patch that fiber coalescence pad in the said coalescence degreaser is knitted silk one-tenth by multilayer nylon ultrafine fiber, vegetable fibre constitutes, and mounting height is a 0.8-1.5 rice; The accurate oil removing filter core base material of said accurate oil eliminator is the SS316L ultrafine wire, surface spraying oleophilic drainage promoting agent.
The pipe connecting of pipe connecting, accurate oil eliminator and product water tank between pipe connecting, coalescence degreaser and the accurate coalescence degreaser between pipe connecting, grade one filter and the coalescence degreaser of the pipe connecting that said flash distillation is communicated with air cooler except that oil tank, draw-off pipe, three phase separation jar and the grade one filter of three phase separation jar and the rising pipe of de-ionized interchanger; Be equipped with internally piloted valve and pressure transmitter above all these pipe connectings and the rising pipe; This internally piloted valve and pressure transmitter and Centralized Controller carry out signal and control linkage, and this unit also carries out signal and control linkage with the DCS system.
The operational process of above-mentioned cleaning treatment system is: each road steam condenses of full factory gets into the constant temperature and pressure tower and reduces temperature and pressure, makes each road condensed water unified temperature and pressure in this equipment simultaneously.This equipment is made up of flash distillation oil removing filling and three phase separation jar zoarium, and automatic interlocking device control tower fluid pressure≤0.1MPa is set.But direct reuse after the LP steam that flashes off tank deck coalescence pad in tower is handled, it is directly to recycle behind the water with this part vapor condensation that condensing surface is set.
Three phase separation coalescing-plate filler is set at the bottom of the constant temperature and pressure tower; After flowing through, condensed water can realize the separation of oil, suspended substance and water; This coalescing-plate base material is SS304, and the surface sprays high temperature resistant oleophilic drainage tensio-active agent, condensed water is carried out the preliminary coarse separation of oil slick and slag; When the oil in the condensed water when forming certain thickness at the bottom of the tower, carry out oil extraction through water-oil interface appearance and automatic oil draining valve are chain.But the amount of oil in the DCS system watch-dog if occur a large amount of greasy dirts suddenly, explains that front end master production technique breaks down, and produces a large amount of leakage of oil situation, DCS warning reminding operator simultaneously.
Get into grade one filter after condensed water (113 ℃) is lowered the temperature in the constant temperature and pressure tower, this strainer mainly reduces the content of suspended substance in the water, and have mechanical coke matter, colloid, biological clay and the part that can effectively remove simultaneously in the water are heavily glued oil ingredient.Dress nylon 66 base material fillers in the strainer can high temperature resistant and high efficiency filter.
Get into coalescence degreaser through the pre-filtered condensed water of grade one filter; This oil eliminator mainly act as oil removing; Have part deionization performance simultaneously concurrently, the dress coalescence material has special oleophylic functional group in the equipment, and this coalescer itself has the function of filtration, breakdown of emulsion and absorption; Can effectively remove dispersed oil, dissolving oil and oil in water emulsion in the water, simultaneously pollutents such as iron ion had certain removal effect.Sectional type, stratiform are installed and are removed lubricating pad in the coalescence degreaser, and the coalescence pad is knitted silk by nylon ultrafine fiber, vegetable fibre and become net to combine.General mounting height is 1.2 meters.
The back one-level of this technology is accurate oil eliminator, and this precision oil eliminator is a process section of guaranteeing that water outlet is qualified.Adorn bolted precision in the equipment and remove wick, should remove wick and can guarantee equipment outlet oil-contg≤1.0mg/L, the manufacturing base material of internals is the SS316L ultrafine wire, surface spraying oleophilic drainage promoting agent.
The last step of this system is the de-ionized interchanger, and the dress condensed water is resin dedicated in the equipment, and this resin has high temperature resistant, high scrubbing capacity, excellent anti oxidative stability, thereby guarantees that the ion content after condensed water is handled satisfies the reuse requirement.
The total system full automatic control is connected closely, handles the back effluent quality and can satisfy general boiler reuse requirement, also can be received water quality requirement according to boiler and can adopt different level sections, improves the processing accuracy grade.Can satisfy high-precision effluent quality requirement, be that simultaneously closed handles, avoid the waste of heat energy and by external environmental.And all internals life cycles are all more than 2 years.
The invention has the beneficial effects as follows: structural manufacturing process is perfect, treatment effect and efficient high, automatic control and level of automation height, operating safety, manufacturing and running cost are low, has very high economic benefit and environmental protection, energy-conservation, water-saving benefit.
