Abstract
The utility model relates to a neutralizing water wastewater treatment device used for a plasticizer dioctyl phthalate (DOP) production line. The neutralizing water wastewater treatment device used for plasticizer DOP production line comprises a wastewater discharge header pipe and an oil separator, wherein the wastewater discharge header pipe is connected with a neutralizing separation tank and a washing separation tank. The neutralizing water wastewater treatment device used for plasticizer DOP production line is characterized in that a heat exchanger is arranged between the wastewater discharge header pipe and the oil separator, the wastewater discharge header pipe is connected with a water inlet of the heat exchanger, and an outlet of the heat exchanger is provided with a water discharge pipe which corresponds to the oil separator. A circulating refrigerant inlet, a refrigerant outlet and a sewage draining outlet are arranged in the heat exchanger, and a heat exchanging pipe is arranged in the heat exchanger. By means of the structure, the problem of strong smell on the spot is solved, the working environment is improved, and pollution is reduced. And the structure is beneficial to improving the oil separation effect of wastewater in the oil separator, further lowering the emission standard of the wastewater and improving the recovery rate of the oil phase in the waste water. Besides, the neutralizing water wastewater treatment device used for plasticizer DOP production line has the advantages of being convenient to install and maintain, safe, reliable and the like.
Description
Technical field
The utility model belongs to plasticizer DOP product line wastewater treatment technical field, particularly relates in a kind of plasticizer DOP production line usefulness and the water wastewater treatment equipment.
Background technology
With the washing post, thick ester mixes with NaOH solution in the plasticizer DOP production line, and the middle monoesters acid of thick ester is neutralized into monoesters acid sodium by alkali, and catalyzer is hydrolyzed into the hydrate of TiO2.Material after the neutralization in separate with separating tank, oil phase separates at the washing separating tank after entering washing kettle washing.In and the water of separating tank and washing separating tank directly be disposed to oil trap after in blanking pipe, converging, and then carry out oil removal in the oil trap.Waste water after the oil removal is processed through pump delivery to Sewage Plant.Because it is higher, approximately 90 ℃, volatile to enter the wastewater temperature of oil trap, causing the oil trap top to shroud has volatility fog, causes on-the-spot smell larger, pollutes the ambient air quality, and mix also difficult isolation of oil in waste water, easily cause the discharge of wastewater index higher.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, easy to use, improve Working environment, reduce on-the-spot volatile flavor, the plasticizer DOP production line that improves worker's oil removal efficient with in and the water wastewater treatment equipment.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of plasticizer DOP production line with in and the water wastewater treatment equipment, comprise discharge of wastewater house steward and oil trap, during described discharge of wastewater house steward connects and separating tank and washing separating tank, it is characterized in that: be provided with interchanger between described discharge of wastewater house steward and the oil trap, described discharge of wastewater house steward connects the water-in of interchanger, the outlet installation water shoot corresponding with oil trap of interchanger, described interchanger be provided with circulating refrigerant import, refrigerant exit and sewage draining exit, be provided with heat exchanger tube in the interchanger.
The utility model can also adopt following technical measures:
Be installed with several traverse baffles by spacing tube and pull bar in the described interchanger.
Described water shoot extends to below the liquid level of oil trap, and is higher than the oil baffle in the oil trap.
Advantage and the positively effect that the utlity model has are: because the utility model adopts technique scheme, between discharge of wastewater house steward and oil trap, be provided with interchanger, reduce the problem of wastewater temperature by interchanger, thereby solved the large problem of on-the-spot smell, improve Working environment, reduced pollution, and be conducive to promote the oil removal effect of waste water in oil trap, and further reduced the emission standard of waste water, improve the rate of recovery of oil phase in the waste water; The utility model also has the advantages such as convenient for installation and maintenance, safe and reliable in addition.

Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1 and Fig. 2, a kind of plasticizer DOP production line with in and the water wastewater treatment equipment, comprise discharge of wastewater house steward 1 and oil trap 2, during described discharge of wastewater house steward 1 connects and separating tank 3 and washing separating tank 4, be provided with interchanger 5 between described discharge of wastewater house steward 1 and the oil trap 2, interchanger is fixedly mounted on the oil trap ground on every side by fastening piece, described discharge of wastewater house steward 1 connects the water-in 5-1 of interchanger, the outlet 5-2 of interchanger installs the water shoot 5-3 corresponding with oil trap, described interchanger 5 be provided with circulating refrigerant import 5-4, refrigerant exit 5-5 and sewage draining exit 5-6 are provided with heat exchanger tube 5-7 in the interchanger 5.Described interchanger adopts countercurrent flow, and the recirculated water that its refrigerant adopts production line to use is by the temperature of recirculated cooling water reduction waste water.
In order to improve heat exchange property, in described interchanger, be installed with several traverse baffles 5-10 by spacing tube 5-8 and pull bar 5-9.
In order further to reduce volatilization, described water shoot 5-3 extends to below the liquid level of oil trap 2, and is higher than the oil baffle 2-1 in the oil trap.
Although the above is described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
