Specific embodiment

As shown in Figure 1 and Figure 2, VOCs separator in a kind of waste water of the utility model, including air blower 1, finned heat exchanger 2, degassing tower 3, circulating pump 4, degassing tower 3 include tower reactor 5, tower section 8, and tower section 8 is connect with the top of tower reactor 5, on the side of tower reactor 5 Portion is equipped with air intlet 6, and air blower 1, finned heat exchanger 2, air intlet 6 are sequentially connected with, and another side lower part of tower reactor 5 is equipped with useless One upper lateral part of water out 17, tower section 8 is equipped with waste water inlet 13, and the other side of tower section 8 corresponds to be equipped at 13 position of waste water inlet Refluxing opening 16, wastewater outlet 17, circulating pump 4, refluxing opening 16 are sequentially connected with, and the top of tower section 8 is equipped with gas outlet 14, in tower section 8 Demister 15, distribution apparatus is from top to bottom arranged in sequence, for distribution apparatus at least provided with two groups, waste water inlet 13, refluxing opening 16 are equal It is arranged between demister 15 and distribution apparatus.

Air is blasted by air blower 1, and finned heat exchanger 2 passes through raw saturated vapor and heats to the air blasted, is then passed through Air intlet 6 is delivered in degassing tower 3, and waste water is delivered in degassing tower 3 through waste water inlet 13, and waste water moves downward, and heating is empty Gas moves upwards, and after waste water comes into full contact with heating air, waste water conveys again through wastewater outlet 17, circulating pump 4, refluxing opening 16 To degassing tower 3, multiple circular treatment carried out to waste water, processing to after to a certain degree according to a certain percentage by waste water outlet, Air, through 14 outlet of gas outlet, thus completes the separation of VOCs in waste water after 15 foam removal of demister.

The utility model separation process processing be simple and convenient to operate, separating effect is stable, it is practical, have a wide range of application.

The utility model heats air using finned heat exchanger 2, and according to the characteristic of VOCs, temperature is higher, molten Xie Du is lower, when heating air and waste water come into full contact with, carries out heat conversion, reduces solubility of the VOCs in waste water, makes VOCs is more preferably detached from from waste water, improves the separative efficiency of VOCs in waste water.

The utility model persistently carries out air delivery using air blower 1, and persistently has under the action of finned heat exchanger 2 and add Hot-air is conveyed through air intlet 6 into degassing tower 3, further decreases solubility of the VOCs in waste water at air intlet 6, from And can be realized degassing purpose more thoroughly, improve the separative efficiency of VOCs in waste water.

The distribution apparatus of at least two groups is equipped in the utility model tower section 8, distribution apparatus makes waste water and heating air distribution Uniformly, increase waste water and heat the contact area of air, so that waste water and heating air is carried out more fully heat and convert, prevent from giving up Water causes gas-liquid contact insufficient with heating each self aggregation of air.

Further, distribution apparatus includes the distributor 11 being from top to bottom sequentially arranged, filler 10, and filler 10, which is fixed on, to be filled out In material support 9.

Further, deflector 12 is equipped between adjacent distributions device, the lower part of packing support 9 is arranged in deflector 12, Deflector 12 slopes inwardly setting from top to bottom.Deflector 12 guarantees that the liquid flowed out through upper one group of distribution apparatus converges water conservancy diversion To next group of distribution apparatus.

Further, as shown in figure 3, distributor 11 includes chassis 111, several liquid separation slots are equidistantly equipped on chassis 111 112, the inner wall of each liquid separation slot 112 is equipped with several liquid separation columns 113, and liquid separation column 113 is to be connected to upper and lower opening with chassis 111 Communicating structure.Waste water carries out branch's water conservancy diversion through liquid separation column 113, is evenly distributed, and prevents liquid accumulation confluence from causing gas-liquid contact not Sufficiently, VOCs separating effect in waste water is influenced.

Further, filler 10 is Raschig ring polytetrafluoro filler.

Further, as shown in figure 4, the top of tower reactor 5 is equipped with gas-liquid intersection connection section 7, gas-liquid intersection connection section 7 Including cavity 71, the top of cavity 71 is equipped with the first intersection 72 connecting with tower section 8, and each side of cavity 71 is equipped with the Two intersections 73.It heats air successively to enter in tower section 8 through the second intersection 73, the first intersection 72, waste water is successively through first Intersection 72, the second intersection 73 enter in tower reactor 5, and the setting of gas-liquid intersection connection section 7 can be realized to heating air, give up Water carries out shunting function, had both prevented waste water from falling in tower reactor 5 and has caused heating air that cannot normally rise because flow is excessive, And then the phenomenon that causing separation to be interrupted, also solve to cause liquid in tower section 8 cannot normally fall since 1 wind pressure of air blower is excessive Problem.

Further, demister 15 uses wire mesh demister, can effectively remove the mist carried secretly in gas.

Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this The various changes and improvements that the technical solution of utility model is made should all fall into the protection that the utility model claims book determines In range.
