Description

Oily water separation and acid-base neutralisation groove
Technical field
The present invention relates to chemical technology field, specifically is a kind of oily water separation and acid-base neutralisation groove that is used for the production of biodiesel field.
Background technology
Along with the fast development of world economy, the production technology of every profession and trade is brought in constant renewal in, and constantly pursues more economical more practical technical process and equipment.Day by day under the condition of limited, biofuel enjoys favor as a kind of new bioenergy at the petrifaction diesel reserves.At present, be rectification under vacuum technology more widely to the separation purification applications of biofuel, so the rectification under vacuum of biofuel is a step of most critical in the production of biodiesel process, its rectifying good and poor directly has influence on the yield and quality of biofuel.In the rectification under vacuum process of biofuel, the lower boiling acidic substance in the grease get into vacuum system like components such as low molecular carboxylic acid, low carbon chain grease, phenol, aldehyde from the vacuum column top; And sneak into the water coolant of water-ring pump and get into circulating water system, cause recirculated cooling water to receive oil pollution, and cause the water body souring and corrode water-ring pump and circulating water pipeline; Make the stopping property variation of water-ring pump; Influence the vacuum tightness of the pump housing, and then reduce the vacuum tightness of rectification under vacuum tower, reduce separating effect.
Summary of the invention
The technical problem that the present invention will solve provides a kind of oily water separation and acid-base neutralisation groove; This oily water separation and acid-base neutralisation groove are arranged between the circulating water pool of water-ring pump and circulating water system; Can prevent effectively that oil from getting into circulating water pool; Realize oily water separation, reduce water body acidity, avoid water body corrosive purpose.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
Oily water separation and acid-base neutralisation groove comprise cell body, and said cell body is divided into water tank and fuel tank, and the bottom of water tank and fuel tank is communicated with, and top is cut off by dividing plate; Said fuel tank is connected with inflow pipeline and flowline, and inflow pipeline stretches in the fuel tank, and flowline is connected in the oil outlet of fuel tank side wall upper part; Said water tank is provided with wet-pit outward, and wet-pit and water tank pass through pipe connection; Said water tank also is provided with the pH determinator outward, and said pH determinator passes tank top through circuit and is connected with the pH detection head, and this pH detection head is located in the water tank.
Wherein, the position of said oil outlet is higher than the dividing plate bottom.And said inflow pipeline is positioned at the position of the mouth of pipe of fuel tank, is between oil outlet and the dividing plate bottom.
Further, liquid level maintains certain height in the groove in order to make, and avoids water in the groove to be drained or overflow, and said tank top is provided with fluid level controller, and this fluid level controller is connected with wet-pit through circuit.Simultaneously, said fluid level controller is connected with level probe and following level probe, and the said level probe of going up is located in the water tank with following level probe.And the said position of level probe down is higher than the dividing plate bottom.
The invention has the beneficial effects as follows:
1, the present invention can realize oily water separation making water-ring pump not by oil corrosion oil phase at a distance from groove and do not get into circulating water pool, postpones its life-span, plays the effect of protection water-ring pump, and then guarantees the vacuum tightness of vacuum column, guarantees that the rectifying of biofuel is carried out smoothly.
2, the oil-water mixture of bringing into from inflow pipeline has non-condensable gases, and the part non-condensable gases can be dissolved in and get into circulating water system in the water, and makes recirculated water become acidity, and the corrosion pump housing and transport pipe; Can in groove, knock down an amount of sodium hydroxide, thereby further neutralize the acidic substance in the circulating water pool according to the pH pH-value determination pH of pH determinator of the present invention, avoid the water body corrosion.

Embodiment
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.
As shown in Figure 1, oily water separation and acid-base neutralisation groove comprise cell body 1, and said cell body 1 is divided into water tank 4 and fuel tank 2, and the bottom of water tank 4 and fuel tank 2 is communicated with, and top is cut off by dividing plate 3; Said fuel tank 2 is connected with inflow pipeline 11 and flowline 9, and inflow pipeline 11 stretches in the fuel tank 2, and flowline 9 is connected in the oil outlet 10 of fuel tank 2 side wall upper part; The said water tank 4 outer wet-pits 8 that are provided with, wet-pit 8 passes through pipe connection with water tank 4; Also be provided with pH determinator 12 outside the said water tank 4, said pH determinator 12 passes water tank 4 tops through circuit and is connected with pH detection head 5, and this pH detection head 5 is located in the water tank 4.
Wherein, the position of said oil outlet 10 is higher than dividing plate 3 bottoms.And said inflow pipeline 11 is positioned at the position of the mouth of pipe of fuel tank 2, is between oil outlet 10 and dividing plate 3 bottoms.
Further, liquid level maintains certain height in the groove in order to make, and avoids water in the groove to be drained or overflow, and said water tank 4 tops are provided with fluid level controller 13, and this fluid level controller 13 is connected with wet-pit 8 through circuit.Simultaneously, said fluid level controller 13 is connected with level probe 6 and following level probe 7, and the said level probe 6 of going up is located in the water tank 4 with following level probe 7.And the said position of level probe 7 down is higher than dividing plate 3 bottoms.
