Specific implementation mode
In the description of the present invention, it should be understood that term " longitudinal direction ", " transverse direction ", "upper", "lower", " preceding ", The orientation or positional relationship of the instructions such as " rear ", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" be based on Orientation or positional relationship shown in the drawings is merely for convenience of description the utility model, does not indicate or imply the indicated dress It sets or element must have a particular orientation, with specific azimuth configuration and operation, therefore should not be understood as to the utility model Limitation.
The technical solution of the utility model, a kind of VOC gas processing unit, including paint spray booth 7 is described in detail in conjunction with attached drawing The processing unit being connected with paint spray booth is provided with negative-pressure air fan in paint spray booth, and processing unit includes air-introduced machine 1, liquid reserve tank 2, Overflow Tower 3 and outlet pipe 4 are provided with admission line 5 and discharge duct 6 on air-introduced machine, and admission line is connected with paint spray booth Logical, discharge duct is connected with the side wall of Overflow Tower, is provided with run-off 8 at the top of Overflow Tower, run-off bottom is provided with drain Pipe 9, run-off top are connected with outlet pipe, and the through-hole 10 that drain pipe is arranged by run-off bottom is connected with Overflow Tower Logical, liquid reserve tank is connected by pipeline with overflow tower bottom, and liquid reserve tank is internally provided with ultrasonic electrode probe 11, and liquid reserve tank is logical It crosses inlet tube 12 with run-off to be connected, water pump 13 is provided on inlet tube.
When handling the VOC gas that paint spray booth generates, first treatment fluid can be put into liquid reserve tank, treatment fluid includes Decomposed solution and absorbing liquid:
Decomposed solution:Sodium citrate 5~10%, sodium acetate 5~10%, neopelex 3~5%, water 75%~ 87%.(Quality proportioning utilizes the similar principle that mixes of organic chemistry)
Absorbing liquid:Iron chloride 1~5%, EDTA 1~3%, protein degrading enzyme 7~20%, water 72%~ 85%.(Quality proportioning, it is theoretical using Hitman's bimodulus)
Decomposed solution absorbing liquid liquid is according to 6~10:3~7 mass ratio is uniformly mixed and is configured to treatment fluid.Treatment fluid It can be recycled, only need to add appropriate tap water in complex liquid, replace primary, pollutant decomposable asymmetric choice net, no sedimentation within about 3-6 months Object, non-secondary pollution, be not necessarily to special wastewater collection controlling device, after replacement waste liquid can it is in line enter city planting ductwork processing, processing Treatment fluid is pumped into run-off after being put into liquid reserve tank by water pump by liquid to be accumulated in run-off, when treatment fluid height accumulate to It is flowed into Overflow Tower from drain pipe after at the top of drain pipe and forms water curtain, the negative-pressure air fan in paint spray booth makes to be formed in paint spray booth at this time Fallout winds, the VOC gas in fallout winds pass sequentially through after admission line, air-introduced machine and discharge duct enter in Overflow Tower and pass through place The water curtain for managing liquid, when fallout winds are raised across water, VOC gas carry out reaction treatment with treatment fluid, and then fallout winds pass through overflow It is expelled in air from outlet pipe behind pond, treatment fluid after being reacted with VOC gas is back to liquid reserve tank by Overflow Tower In, ultrasonic electrode probe is opened at this time, and the ultrasonic wave of 100~1000kHz can instantaneously generate high temperature and pressure by solution; Small complex in body is intensified under the action of sound wave, while being generated with strong impacts with the speed of about 110m/s Microjet and shock wave, the following reaction of liquid internal generation at this time:
1, partial organic substances are because the pyrolytic reaction similar to burning occurs for high temperature and pressure;
2, partial organic substances or water enter free radical (H, HO, HOO, O etc. of formation strong oxidizing property after cavitation bubble pyrolysis ), part free radical has the freedom that can be generated with cavitation in conjunction with the oxygen and H2O2 for forming free state, organic matter soluble in water Base and H2O2 carry out a series of reaction, and to make, organic pollution directly decomposes or free-radical oxidation is degraded;
3, the mechanical effect of ultrasonic wave can be such that the carbon key on macromolecular main chain is broken, to play degraded macromolecular Effect;
Treatment fluid after being reacted with VOC gas by the treatment and purification of ultrasonic electrode probe, enables treatment fluid to repeat It utilizes.
It is provided with zigzag overflow port 15 within one week at the top of drain pipe, the treatment fluid in run-off is enable to pass through overflow Mouth uniformly flows into Overflow Tower, and there are two branched discharge pipe 14, branched discharge pipe end symmetric is set to for the end setting of discharge duct The side wall of Overflow Tower is simultaneously connected with Overflow Tower, and the fallout winds entered from branched discharge pipe road at this time enter Overflow Tower, and exhaust gas is wanted It is discharged outward, it is necessary to be contacted with water curtain, then ensure that exhaust gas is contacted with water curtain 100%, in the pipeline between liquid reserve tank and Overflow Tower It is provided with filter screen 16, for filtering the paint slag and dust carried secretly in fallout winds.
The basic principle of the utility model, main feature and advantage has been shown and described above, it is new not departing from this practicality Under the premise of type spirit and scope, the utility model also has various changes and modifications, these changes and improvements both fall within requirement and protect The scope of the utility model of shield.
