Technical Field
The utility model relates to a waste gas treatment technical field, a waste gas absorbs purifier specifically says so.
Background
Along with the development of science and technology, the emission of polluted gases is obviously increased, and especially in recent years, environmental-friendly alarm clocks are knocked on the global scale. However, the common waste gas treatment process has many disadvantages, which not only affect the normal production, but also relate to the ecological environment in which people live, and is one of the more serious problems faced by the common waste gas treatment process at present.
Industrial waste gases are formed in industrial processes and different ways of exhausting may be required depending on the composition of the waste gases. The air exhaust mode mainly comprises three modes of natural air exhaust, local air exhaust and full air exhaust. The production factory building which does not produce waste gas or produces waste gas with little influence on the environment can adopt natural air exhaust, and the natural air exhaust mode can be comprehensively considered from aspects of ventilation design, general diagram arrangement, building design, process configuration and the like. For a production factory building which can generate toxic, harmful and explosive gases in the production process, the natural air exhaust is not feasible, forced air exhaust is needed, and waste gas in the factory building is collected and concentrated through an air exhaust pipeline and then is treated and discharged.
The common waste gas is treated by a single spray tower and then is discharged to the high altitude by a fan connected with an exhaust cylinder, and the exhaust mode has large exhaust volume and can discharge polluted gas to the air.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the prior art, the utility model aims to provide a waste gas absorbs purifier, the waste gas that produces in the efficient handling production process prevents the exhaust gas polluted environment, and this waste gas absorbs purifier can also collect the hydrogen chloride gas and recycles simultaneously.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a waste gas absorbs purifier, includes absorption tower and purifying column, its technical essential is: the absorption tower is connected with the purification tower through a pipeline, the absorption tower comprises an absorption tower body, liquid water is filled in the absorption tower body, the left side surface of the bottom of the absorption tower body is connected with a hypochlorous acid solution outlet, and the right side surface of the bottom of the absorption tower body is connected with a waste inlet; the purifying tower is including the purifying tower body, the inside bottom packing of purifying tower body has sodium hydroxide solution, purifying tower body bottom side-mounting has spray water inlet pipe, a side is provided with the shower above the purifying tower body, purifying tower body top is provided with gas outlet.
The utility model has the advantages and beneficial effects that: the utility model discloses a waste gas absorption purifier who protects can the effective processing production in-process waste gas that produces, can also collect hydrogen chloride gas and be used as the water of leaching, reduce cost.
