Abstract
The utility model relates to the field of production of reagent hydrochloric acid and provides an environment-friendly recovery device for the tail acid of the reagent hydrochloric acid. The environment-friendly recovery device comprises a hydrochloric acid tail gas collection pipe and a sealed absorbing barrel contained with water, wherein the absorbing barrel consists of a first absorbing barrel and a second absorbing barrel which are communicated with each other by exhaust pipes of the tops of the barrels, the lower parts of the absorbing barrels are provided with collection valves, the hydrochloric acid tail gas collection pipe is inserted in the first absorbing barrel, and a plurality of micropores are formed in the bottom end and the bottom end face of the hydrochloric acid tail gas collection pipe. The recovery device provided by the utility model performs secondary recovering on the hydrochloric acid tail gas generated in the process of purifying and filtering technical hydrochloric acid to produce the reagent hydrochloric acid, thereby not only solving the environment pollution problem but also playing a role in energy source secondary recycling and cost reduction.
Description
Technical field
The utility model relates to the manufacturing field of reagent hydrochloric acid, relates in particular to the environmental protection retracting device of a kind of reagent hydrochloric acid tail acid.
Background technology
Generate in the process of reagent hydrochloric acid in technical hydrochloric acid purification and filtration, hydrochloric acid tail gas is after once reclaiming, the gas of discharging does not reach standard usually, such tail gas not only can pollute worker's production environment, if there is not appropriate processing, also can damage natural environment, also cause the waste of the resources of production simultaneously.
Summary of the invention
The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art; the environmental protection retracting device of a kind of reagent hydrochloric acid tail acid is provided; it is purified to technical hydrochloric acid and filters the hydrochloric acid tail gas that generates in the reagent hydrochloric acid process and carry out secondary recovery; not only solved problem of environmental pollution; also play the energy source secondary recycling, reduced the effect of cost.
For realizing above purpose; the technical solution adopted in the utility model is: the environmental protection retracting device of a kind of reagent hydrochloric acid tail acid; comprise hydrochloric acid tail gas collecting pipe and the airtight absorption bucket that water is housed; described absorption bucket comprises that first absorbs bucket and the second absorption bucket; the first absorption bucket and second absorbs barrel blast pipe by barrel top and is communicated with; the described bottom that absorbs bucket is equipped with the collection valve; described hydrochloric acid tail gas collecting pipe inserts first and absorbs in the bucket, and the end of hydrochloric acid tail gas collecting pipe and terminal surface are provided with some apertures.
In technique scheme, the hole diameter on the described hydrochloric acid tail gas collecting pipe is 2 millimeters.
The described top that absorbs bucket also is provided with to regulate the exhaust-valve of internal pressure, and water inlet pipe.
Compared with prior art, the beneficial effects of the utility model are:
1, simple in structure, easy to use, absorb the hydrochloric acid tail gas of discharging by the absorption bucket of two dress water, aqueous fusion in hydrochloric acid tail gas and the airtight absorption bucket is closed, when the content of hydrochloric acid in absorbing bucket is up to standard, can also receive finished acid by the valve that absorbs the bucket bottom, reach the purpose that energy source secondary is recycled.
2, the utility model is used in useful environmental protection, and the hydrochloric acid tail gas that discharges is carried out secondary recovery, and through after the secondary recovery, the gas of discharging has reached national pollution emission standard.
Description of drawings
Fig. 1 is the structural representation of the environmental protection retracting device of the utility model reagent hydrochloric acid tail acid.
Wherein, hydrochloric acid tail gas collecting pipe 1, aperture 2, first absorb bucket 3, second and absorb bucket 4, blast pipe 5, collection valve 6.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Referring to Fig. 1; the present embodiment provides the environmental protection retracting device of a kind of reagent hydrochloric acid tail acid; comprise hydrochloric acid tail gas collecting pipe 1 and the airtight absorption bucket that water is housed; described absorption bucket comprises that first absorbs bucket the 3 and second absorption bucket 4; first absorbs bucket the 3 and second absorption barrel 4 blast pipes 5 by the bucket top is communicated with; the described bottom that absorbs bucket is equipped with collects valve 6, and described hydrochloric acid tail gas collecting pipe 1 inserts first and absorbs in the bucket 3, and the end of hydrochloric acid tail gas collecting pipe 1 and terminal surface are provided with some apertures 2.
In the above-described embodiments, aperture 2 diameters on the described hydrochloric acid tail gas collecting pipe 1 are 0.2 centimetre.
When using the utility model, technical hydrochloric acid is being heated in the process of purification, at first by pipeline the hydrochloric acid tail gas that generates is imported hydrochloric acid tail gas collecting pipe 1, aperture 2 and the first aqueous fusion that absorbs in the bucket 3 that hydrochloric acid tail gas sees through on the collecting pipe are closed, when the content of hydrochloric acid in the first absorption bucket 3 is up to standard, receive finished acid by the first collection valve 6 that absorbs bucket 3 bottoms, unreacted is hydrochloric acid tail gas completely, introduce second by the first blast pipe 5 that absorbs bucket 3 tops again and absorb bucket 4, carry out secondary recovery, through after the secondary recovery, the gas of discharging has reached national pollution emission standard.
Below only be that preferred embodiment of the present utility model is described; be not to its circumscription; do not break away from, under the prerequisite of the utility model design concept; the technical solution of the utility model is made various distortion and transformation, all should fall within the definite protection domain of claims of the present utility model.
