Description
Technical field
The invention belongs to petroleum industry oiliness sewage treatment field, in particular to a kind of efficient crater plate degreasing unit.
Background technique
Oily waste water is a kind of pair of natural environment, the ecological balance, aqueous bio and further jeopardizes human body health
Polluter.This polluter is mainly generated from petroleum industry, in the generation of petroleum, processing, refinement, storage and transport
Oily waste water can be all generated in the process.
The harm of oily waste water mainly has the following aspects: forming oil film, prevents oxygen from being dissolved in water, lead to aquatic organism
Due to water oxygen level reduction, anoxic is lethal；Lead to the shrimp to live in oily waste water for a long time, in flesh of fish containing peculiar smell and
It cannot eat；The photosynthesis of water plant is hindered, the self-purification function of water body is further influenced, can seriously water quality be caused to degenerate,
Destroy water resource；The oil slick of water surface is there are flammable problem, and there are security risks.Therefore, it in order to purify oily waste water, prevents
The generation of the above problem, frequently with efficient degreasing technology.
Efficient crater plate degreasing unit has a characteristic that 1) efficiently recessed as a kind of novel efficient degreasing technology
Hole plate degreasing unit increases coalescence area, increases oil droplet collision probability, improves separative efficiency；2) due to crater plate oil removing
The problem of independence of the raised fourth born of the same parents of device, there is no longitudinal stream transverse flows, solving corrugated plating, longitudinally stream only increases coalescence
Area and the problem of special coalescence form can not be formed；3) since crater plate is symmetrically put, it is first up and then down to form " inverted V type " progress
It coalesces twice, further increases coalescence area, improve separative efficiency；4) since crater plate multilayer parallel tilts 60 degree of pendulum
It puts, meets shallow pool theory, reduce oil droplet floating interval of floating dock, improve separative efficiency；5) crater plate degreasing unit is due to raised fourth born of the same parents'
Effect makes solution generate disturbance in separation, and easily forms turbulent flow, the probability of oil droplet collision is increased, to improve separation
Efficiency.
The processing of oily waste water is paid attention to by people deeply, and therefore, the device of oil removing is also various, but it is inefficient always
The problem of being people's puzzlement.Such as have the following problems: 1) being separated into mostly using inclined plate, corrugated plating separation, there is separation effect
The limitation that rate cannot greatly improve；2) separator uses single separation mostly, and separative efficiency is very low.Even if using a variety of
Mode combines separation, but there are pre-treatments and post-processing to be connected not perfect problem for existing combination isolation technics, for example enters poly-
Sludge discharge is not clean before interface, is easy to produce hardened；3) counting apparatus does not have self-purification function mostly, causes blowdown not clean, and formed
Accumulative residual increases oiliness sewage treatment cost to reduce the service life of separator.
Efficient degreasing technology is of great significance, however, the patent about crater plate oil removing is less, the patent No.
" 201510393173.1 " disclose a kind of Novel coalescence-inclined plate oil expeller, which uses coarse area and Disengagement zone phase
In conjunction with the characteristics of, relatively it is single separation improve separative efficiency.The shortcomings that device, is: inclined plate separative efficiency there are limitation,
Traditional separation phase is only rested on, in addition, blowdown problem is not pointed out in the pre-treatment in coarse area, is easy to cause coarse area
Generate hardened phenomenon.The patent No. " 201410475981.5 " discloses a kind of efficient inclined plate oil removing sand-catching apparatus, which creates
According to the inclined plate that the vortex street column of spiral of Archimedes distribution is connected in series, but it still only considered single separation not
Consider multi-stage separation problem.Therefore, under identical oily waste water medium, more efficient point can be reached using crater plate degreasing unit
From effect.
Summary of the invention
