Description
Technical field
The utility model relates to Sewage treatment reutilization technology field, refer in particular to for dead livestock and poultry harmless treatment
A kind of oily waste water oil extraction plant.
Background technique
In the prior art, the material of dead livestock and poultry harmless treatment center processing is to be generally dead livestock and poultry trunk, reference
China Light Industry Press in 2011 publishes, TanJin Agricultural College Kong Baohua edit " the m eat sciences and technology " second edition and
United States Department of Agriculture's animals and plants sanitary inspection office (APHIS) collaborative project in 2004 " animal carcasses disposition summary " is it is found that dead livestock and poultry is innoxious
The chemical constituent of the material (dead livestock and poultry trunk) of processing are as follows: the solids such as moisture about 70%, protein about 20%, grease are about
10%.In innocent treatment procedure, animal fat can be entered in draining dead livestock and poultry by the approach such as evaporating, cleaning.According to
Domestic and international multiple item detection data, the fat content in dead livestock and poultry harmless treatment draining is about 2000~4500mg/L,
Average each project drains about 10m3/d。
Currently, the whole nation is built and about 432, the innoxious center of dead livestock and poultry built, handles sick dead pig about 60,000,000 in year
(about 1,500,000 tons).About 2592 tons~5832 tons of fat content can be extrapolated in 432 dead livestock and poultry harmless treatment center drainings
(account for about fat content in charging 1.7%~3.9%).Grease in these drainings is very big to natural environment water pollution, (ginseng
It examines GB8978-1996 " integrated wastewater discharge standard ", the fat content in draining is necessary≤10mg/L) therefore industry demand is hundreds of
Platform draining proposes oily equipment.
Existing to propose oily equipment and generally use parallel flow intercepter, draining is flowed into from one end of oil separator, with lower level
Flow velocity water distribution in oil separator.The oil droplet that density is less than water in flow process rises to the water surface, and density is greater than the granule foreign of water
It is sunken to bottom of pond.Draining is flowed out from the other end of oil separator.Oil collecting pipe is set in the water outlet of oil separator, oil collecting pipe generally uses
DN200~DN300 welded still pipe production, in the oil-collecting notch of 90 ° of the side open arc degree of tube wall.Oil collecting pipe can back and forth be transported around axis
Dynamic, when oil extraction, rotates the fluting of oil collecting pipe to water body liquid level hereinafter, collecting oil slick, then rotate and pour out oil slick.Flat flow oil removal
The characteristics of pond is mechanical realization simple, maintenance and convenient for management.The minimum droplet diameter that parallel flow intercepter can remove is 100
~150um, the corresponding rate of climb are not higher than 0.9mm/s.
Although parallel flow intercepter has more application case in dead livestock and poultry harmless treatment draining, there are still one
Fixed defect: one, it is difficult to oil emulsion.Grease exists in draining with four kinds of states, i.e. oil slick, oil emulsion, dissolved oil and solidifying
Poly- state residue.Parallel flow intercepter is bad to emulsification, dissolution, the grease treatment effect of three kinds of states of residual.Two, room temperature
Lower than the freezing point of grease, after grease enters parallel flow intercepter, freeze wherein it is difficult to remove.Three, parallel flow intercepter lacks
Sterilizing function.
