Abstract
The utility model relates to a purified acid wastewater degasser, in particular to a device for degassing the acid wastewater purified and discharged by a sulfuric acid system. The purified acid wastewater degasser is characterized by comprising a device box, a degassing chamber, a liquid sealing chamber which are separated by a partition board with the lower ends communicated, a wastewater discharge pipe arranged on the side wall of the degassing chamber of the device box, a wastewater inlet pipe and an exhausting pipe which pass through the box top plate of the degassing chamber of the device box, and a liquid sealing chamber liquid injection hole arranged on the box top plate of the liquid sealing chamber. The purified acid wastewater degasser is additionally provided with a degassing pipe at the highest point, pumps the SO2 separated out of the acid wastewater in a water seal to the production system by negative pressure so as to degas the SO2 in the purified and discharged acid wastewater, not only can discharge the acid wastewater and prevents the SO2 from escaping, but also can recover all the SO2 to prepare acid and has good effect.
Description
Technical field
A kind of purification acid waste water de-gassing vessel relates to a kind of device of the degassing when being used for sulfate system and purifying the pickling waste waters discharging.
Background technology
Utilizing the sulfate system of metallurgical off-gas acid-making, the purification system of flue gas is to adopt the wet scrubbing technological process of production basically, no matter is that water washing cleaning or weak acid scrubbing purify, and all has the acid waste water of some amount to be discharged unified the processing.Yet the diluted acid of cleaning section in the circulation cleaning process, in the diluted acid except being dissolved with flue dust, SO
3Outside impurity, the part SO in the flue gas
2Also be dissolved into wherein.In purifying the acid waste water discharge process, part SO
2Gas parses from acid waste water, and loss everywhere not only has influence on operator safety, causes site environment to pollute simultaneously.Because acid waste water is not handled through the degassing, is dissolved in a large amount of SO in the acid waste water
2Gas is in flow process, and well and downstream sewage master station etc. overflow under the pipeline of discharging on the way, the people that not only chokes everywhere, and cause environmental pollution, cause limited sulphur resource to be wasted in a large number simultaneously.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, provides a kind of easy and simple to handle, maintenance convenience, the purification acid waste water de-gassing vessel of less investment, instant effect.
The purpose of this utility model is achieved through the following technical solutions.
A kind of purification acid waste water de-gassing vessel is characterized in that its structure comprises:
Device box-this casing is a shell-type casing, the degassing cavity and the fluid-tight cavity of two lower end UNICOMs that the dividing plate that casing is opened by the upper end that is provided with in the casing and roof box sealed attachment, lower end is divided into;
Wastewater discharge pipe-this delivery pipe is located at the sidewall of device box degassing cavity;
Waste water liquid-inlet pipe-this liquid-inlet pipe passes the roof box of device box degassing cavity, and outlet end is lower than wastewater discharge pipe;
Extraction pipe-this extraction pipe passes the roof box of device box degassing cavity, and its port is higher than wastewater discharge pipe;
Fluid-tight cavity liquid filling hole-this liquid filling hole is located on the fluid-tight cavity device roof box.
A kind of purification acid waste water de-gassing vessel of the present utility model installs extraction pipe additional at the vertex of acid waste water de-gassing vessel, utilizes negative pressure, and water seal inner acidic waste water is taken off the SO that separates out
2The gas pumpback in production system, thereby reach SO in the emission abatement acid waste water
2The degassing of gas; Acid waste water can be discharged, prevent SO
2Gas escapes, again can be with SO
2Gases with total recovery relieving haperacidity, respond well.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of purification acid waste water de-gassing vessel, its structure comprises:
This casing of device box 1-is a shell-type casing, the degassing cavity and the fluid-tight cavity of two lower end UNICOMs that the dividing plate 2 that casing is opened by the upper end that is provided with in the casing and roof box sealed attachment, lower end is divided into;
This delivery pipe of wastewater discharge pipe 3-is located at the sidewall of device box degassing cavity;
This liquid-inlet pipe of waste water liquid-inlet pipe 4-passes the roof box of device box degassing cavity, and outlet end is lower than wastewater discharge pipe;
This extraction pipe of extraction pipe 5-passes the roof box of device box degassing cavity, and its port is higher than wastewater discharge pipe;
This liquid filling hole of fluid-tight cavity liquid filling hole 6-is located on the fluid-tight cavity device roof box.
Device sulfate system of the present utility model purifies the acid waste water discharge tube and degassing pipeline all adopts the FRP material, in order to save degassing pipeline, the acid discharge pipeline is more bigger with caliber, be all to be taken by acid waste water in the pipeline, usually should be with a gradient slightly, enter the de-gassing vessel ingress and should be lower-most point, otherwise also need add a degassing pipeline in addition.Install a deaeration pipe like this at acid waste water de-gassing vessel top additional and can realize SO in the acid seal
2Gas recovery.
Sulfate system purifies the acid waste water de-gassing vessel can make whole water seal casing with PVC slab or FRP material, places lower position.Certainly also can make the pond, ground and adopt brick mix structure, the acid-resistant anti-corrosion layer is done in inside.
During operation, utilize deaeration pipe to bleed, utilize negative pressure, water seal inner acidic waste water is taken off the SO that separates out
2The gas pumpback in production system, thereby reach SO in the emission abatement acid waste water
2The degassing of gas; Inject liquid at fluid-tight cavity liquid filling hole, form fluid-tight, promptly prevented SO
2Gas escapes, again can be with SO
2Gases with total recovery relieving haperacidity, respond well.
