Description
Technical field
The present invention relates to a kind of industrial filter and recovering system, particularly a kind of steel rolling alkaline wash filters and recovering system.
Background technology
The techniques such as the cleaning way that adopts with steel cleaning and degreasing process section in process of production is that alkali hydro-peening, alkali are scrubbed, high pressure water hydro-peening, water are scrubbed, water hydro-peening, warm air drying.The cleaning of belt steel surface is the important step in producing with steel, its surface cleaning quality directly affects strip quality, cleaning on the one hand is the greasy dirt that washes surface of steel plate, is dust and the iron rust that washes surface of steel plate on the other hand, is beneficial to the surface treatment with steel.Impurity in the alkaline wash mainly is that the suspended substances such as the grease brought into of belt steel surface and metallic dust, iron scale particle are bonded together, form the iron oil mixt, when its concentration acquires a certain degree, the cleaning quality of alkaline wash will be affected, so iron oil mixt in the alkaline wash must be removed, with the clean-up performance of raising alkaline wash, thereby alkaline wash is recycled, reduce alkaline wash consumption.At present, alkaline wash filters and adopts other filter mode, and mainly there are the following problems:
Mostly adopt basket type strainer+bar magnet filter or paper tape filter, the technology pattern of basket type strainer+magnetic bar filter (excellent chain type magnetic filter) is: basket type strainer purpose is to remove large particle, and magnetic filter can only be by magnetic to iron powder or be with magnetic particle to play the removal effect.Because having apart from the magnetic center, magnetic-particle far has closely, so its adsorption effect has ununiformity, and the impurity such as the nonmagnetic greasy dirt of major part and greasy filth mixture, silicon-dioxide are not had scavenging(action), its filter effect has certain limitation, does not fundamentally shorten the magnitude of recruitment of drain time, reduction alkali lye and the pure water of alkaline wash.
Magnetic filter is not obvious to the removal effect of grease, be easy to owing to grease simultaneously and iron powder adsorption formation greasy filth, bar magnet is in the process of removing iron powder, be subject to especially easily the pollution of grease, need to clean frequently its normal operation of guarantee, the mixing wastewater with air that needs high temperature during its backwash, energy consumption are very large.Cause alkaline wash to be changed frequently owing to can not well remove grease simultaneously, consumption is very large; Frequent grease of discharging also needs to carry out processing up to standard just can entered environment, causes production cost to increase.
Paper tape filter mainly is to remove iron powder, greasy filth (iron oil mixt) and other granule foreigns in the alkaline wash purification filtering, free oil slick is not had filter effect, can pass along the paper tape hole, get back to again in the alkaline wash, oil slick can be cumulative like this, affect the cleaning performance of alkaline wash, simultaneously because the filter paper hole of the paper tape filter that adopts at present is larger, generally be 20 ~ 40 μ m, impurity less than the paper tape hole just is easy to pass paper tape, come back in the alkaline wash, cause for a long time alkaline wash still very dirty.
Summary of the invention
For overcoming above-mentioned deficiency, the invention provides that a kind of to have a deoiling effect good, filtering accuracy is high, liquid is limpid after the filter, do not change other physicochemical characteristics such as alkaline wash character, concentration, liquid fully recovering, dry residue emission, without any environmental pollution, the steel rolling alkaline wash of save energy filters and recovering system.
