Abstract
The utility model relates to a suspending oil removing device capable of treating and cold-milling a surfactant and residual oil in waste water, comprising a suspending oil removing device, a water inlet pipe, a water discharging pipe. The suspending oil removing device is characterized by also comprising an aeration pipe, a smoke discharging pipe and a concentrated liquid pipe, wherein the aeration pipe is connected with the bottom part of the suspending oil removing device; and the smoke discharging pipe is connected with the upper part of the suspending oil removing device and is also respectively connected with a smoke discharging chimney and the concentrated liquid pipe. Compared with the prior art, the suspending oil removing device has the benefits that: the occupied area is less, the equipment investment is less, the removing rate of the surfactant and the residual oil in the waste water containing oil can be effectively improved, the removing rate of the suspending oil can be up to 95%, the cleaning period of a following ultra-filtration device is prolonged greatly, and the water discharging index is effectively improved.
Description
Technical field
The utility model relates to the pretreatment unit in the cold rolling useless newborn treatment process in the steel rolling field.
Background technology
In the steel rolling field, the technology that generally adopts in the oily(waste)water treatment process is: oily(waste)water leaves standstill or pretreatment mode such as air supporting carries out processing in early stage through adding emulsion splitter or heating, waste water discharges after ultrafiltration system filters again then, this kind mode is operational difficulty in use, the cost height, floor space is big, and effect is undesirable.
Summary of the invention
The purpose of this utility model provide a kind of handle tensio-active agent and Residual oil in the cold rolling wastewater remove the oil slick device, this plant area area is little, facility investment is little, can effectively improve the clearance of tensio-active agent and Residual oil in the oily(waste)water.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of handle tensio-active agent and Residual oil in the cold rolling wastewater remove the oil slick device, comprise and remove oil slick device, water inlet pipe, water shoot, it is characterized in that, also comprise aeration tube, smoke exhaust pipe, dope pipe, aeration tube with remove the oil slick bottom of device and be connected, smoke exhaust pipe with remove oil slick device top and be connected, smoke exhaust pipe also is connected with the dope pipe with gas shaft respectively.
Compared with prior art, the beneficial effects of the utility model are:
Floor space is little, and facility investment is little, can effectively improve the clearance of tensio-active agent and Residual oil in the oily(waste)water, and the suspension oil clearance can reach 95%, has greatly prolonged the cleaning interval of subsequent ultrafiltration device, has improved effluent index effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structure iron that removes the oil slick device.
Embodiment
See Fig. 1, Fig. 2, a kind of handle tensio-active agent and Residual oil in the cold rolling wastewater remove the oil slick device, comprise and remove oil slick device 3, water inlet pipe 2, water shoot 5, aeration tube 10, smoke exhaust pipe 4, dope pipe 7, aeration tube 10 with remove oil slick device 3 bottoms and be connected, smoke evacuation 4 is managed and is connected except that oil slick device 3 tops, and smoke exhaust pipe 4 also is connected with dope pipe 7 with gas shaft 6 respectively.
Oily(waste)water is through precipitation process with after going oil slick to handle, enter neutralization tank 1 and carry out neutralizing treatment, enter except that oil slick device 3 by water inlet pipe 2 then, remove the cylindrical tank that oil slick device 3 is made for stainless steel, its diameter is Φ 2000mm, high 2500mm is connected with water inlet pipe 2, water shoot 5, aeration tube 10, smoke exhaust pipe 4 respectively in the perforate of tank body side.Aeration tube 10 adopts the stainless steel tube of Φ 25mm, and gas shaft 6 is installed in the outlet of smoke exhaust pipe pipeline and medicament adds hole 11.
Oily(waste)water enters except that behind the oil slick device 3, with the reverse thorough mixing of pressurized air that feeds by aeration tube 10, a large amount of bubbles that pressurized air produces gather in the enclosed space of device, tensio-active agent and Residual oil in the waste water are adsorbed on the bubble surface, and grow floating on water to the water surface and enrichment forms foam layer with bubble, by adding medicament the surfactant foam layer is further concentrated, the scumming layer can be separated tensio-active agent and Residual oil from water, and unnecessary pressurized air bubble is discharged from smoke exhaust pipe 4 pipelines.After removing 3 processing of oil slick device, waste water is divided into two portions, and a part enters equalizing tank 9 for removing the waste water of tensio-active agent and oil slick by water shoot 5; The foam layer that another part is made up of tensio-active agent and oil slick concentrates the back and is discharged into the 9 processing back recyclings of waste oil storage tanks from dope pipe 7.
Claims (1)
- One kind can handle tensio-active agent and Residual oil in the cold rolling wastewater remove the oil slick device, comprise and remove oil slick device, water inlet pipe, water shoot, it is characterized in that, also comprise aeration tube, smoke exhaust pipe, dope pipe, aeration tube with remove the oil slick bottom of device and be connected, smoke exhaust pipe with remove oil slick device top and be connected, smoke exhaust pipe also is connected with the dope pipe with gas shaft respectively.
