Description
Technical field
The invention belongs to field of industrial waste water treatment, be specifically related to a kind of liquid seal device preventing ozone oxidation tower liquid level from raising.
Background technology
Ozone is strong oxidizer, and its oxidation capacity is only second to fluorine in natural element, utilizes its strong oxidizing property can by degrading industrial waste water.Adopt the reaction of ozonated air process organic waste water fast, there is not secondary pollution, manufacture ozone and only need air and electric energy, there is not raw material transport and storage problem.Higher for pH value, the trade effluent that concentration is lower, can utilize ozone Oxidation Treatment separately, and ozonation technology key equipment is ozonizer.Oxygen is smelly to be produced by high-voltage discharge in producer, the oxidation tank that gac is housed is entered by back-flow preventer, useless Organic substance in water can directly and ozone reaction or decompose the hydroxyl radical reaction of generation with ozone in water, pollutent macromole can be made to be oxidized to small molecules, improve organic biodegradability, and reduce pollution concentration.In oxidation tank by aeration plate all with the bottom being distributed in oxidation tank, pollutent in waste water is oxidized with contacting with each other in waste water up-flow process, and utilize the continuous cyclic oxidation of circulation device, by the adsorption of gac, waste water is further purified in working cycle; Waste water after ozone, activated carbon treatment not easily biochemical heterocyclic material and toxicity all significantly reduces.
Although ozonation technology technical perfection, but liquid level is unfavorable to operation after raising in ozone oxidation tower, waste water in tower may be caused to reflux from the high-order pipe of ozone, the safety of critical ozonizer, common way economizes at tower to establish stream pipe, but the ozone in tower can together be discharged from upflow tube, disperse is inner in worker-house, damages healthy after concentration over-standard.
Summary of the invention
The object of the present invention is to provide a kind of liquid seal device preventing ozone oxidation tower liquid level from raising.Concrete technical scheme is as follows:
The liquid seal device preventing ozone oxidation tower liquid level from raising, comprises preposition ozone oxidation tower, subsequent fluid seal apparatus;
Liquid seal device is made up of communicating pipe, upflow tube, filler pipe, liquid sealing pipe, vent pipe, evacuated tube;
The effect of communicating pipe is that when in tower, liquid level is normal, tower top ozone can pass through, when in tower, liquid level raises, the wastewater pressure of influent tube sealing is identical with tower top pressure, when can ensure waste water semicanal, ozone can pass through simultaneously, also the generation vapour lock in liquid sealing pipe can be prevented, a high position for liquid sealing pipe will lower than upflow tube, and distance is h2;
Liquid sealing pipe is made up of the U-tube of positive U-shaped, and vent pipe is made up of inverted U-shaped U-tube, jointly constitutes the core of liquid seal device after two U-tube a positive and a negative connect;
The height degree h1 of liquid sealing pipe depends on the pressure P 1 of oxidation tower top, must ensure that static pressure that liquid-column height h1 produces is greater than the pressure of tower top; In the pipeline that can ensure two public parts of U-tube like this, the maximum height difference of liquid level is greater than the pressure of tower top, thus the ozone realized in tower can not be discharged from liquid sealing pipe, and waste water can be discharged;
In liquid sealing pipe, adds the raw water that disappears through valve before running, stop adding water in liquid sealing pipe during the outside draining of vent pipe; When oxidizing tower liquid level exceedes regulation liquid level, unnecessary waste water by upflow tube influent tube sealing, and will be discharged through liquid sealing pipe;
A liquid sealing pipe high position is provided with evacuated tube, produces siphon, drained by the water in liquid sealing pipe, thus realize proper drainage when preventing the waste water in liquid sealing pipe from discharging.Liquid seal device can realize ozone and not expose, and in tower, waste water can discharge from upflow tube, and in tower, waste water can discharge from upflow tube, ensure that the safe operation of ozonizer.
Beneficial effect
Liquid seal device of the present invention can realize ozone and not expose, and in tower, waste water can discharge from upflow tube, and in tower, waste water can discharge from upflow tube, ensure that the safe operation of ozonizer.
Accompanying drawing explanation
Fig. 1 is the liquid seal device schematic diagram preventing ozone oxidation tower liquid level from raising;
Embodiment
The liquid seal device preventing ozone oxidation tower liquid level from raising, comprises preposition ozone oxidation tower a, subsequent fluid seal apparatus b;
Preposition ozone oxidation tower a is connected with subsequent fluid seal apparatus b with tower top ozone vent pipe 1 through tower top upflow tube 3;
Subsequent fluid seal apparatus ensures that ozone does not expose, and in tower, waste water can discharge from upflow tube and arrange liquid seal device, effectively can ensure waste water not from the high-order pipe backflow of ozone, ensure that the safe operation of ozonizer.
Liquid seal device (b) is made up of communicating pipe 2, upflow tube 3, filler pipe 4, liquid sealing pipe 5, vent pipe 6, evacuated tube 7;
The effect of communicating pipe 2 is that when in tower, liquid level is normal, tower top ozone can pass through, and communicating pipe 2 is connected with the tower top ozone vent pipe of preposition ozone oxidation tower a, realizes the normal discharge of ozone; When in tower, liquid level raises, the wastewater pressure of influent tube sealing 5 is identical with tower top pressure, can ensure that waste water in ozone oxidation tower a and ozone are simultaneously by liquid sealing pipe 5 simultaneously, ozone enters ozone vent pipe 1 through communicating pipe 2, discharge air after decomposing by catalyst splitter 8, waste water enters liquid sealing pipe 5, can prevent from producing vapour lock in liquid sealing pipe 5, the highest liquid level of liquid sealing pipe 5 will lower than upflow tube 3, and distance is h2; Liquid sealing pipe 5 is made up of the U-tube of positive U-shaped, and vent pipe 6 is made up of inverted U-shaped U-tube, jointly constitutes the core component of liquid seal device b after two U-tube a positive and a negative connect;
