Description
Technical Field
The utility model belongs to the field of hazardous waste liquid treatment, and particularly relates to a pretreatment device of fuming waste acid.
Background
In industrial production, waste acid is produced through the processes of nitration, esterification, sulfonation, alkylation, catalysis, gas drying and the like of organic matters, or through the processes of titanium white production, steel pickling, gas drying and the like.
The waste acid recovered from other companies is contained in a small barrel or a small bottle at present, before the waste acid is sent to a reaction kettle, the waste acid is required to be mixed and treated, the waste acid is collected in a large container and then sent to the reaction kettle, the operation is now manually carried out, acid mist is extremely easy to form in the mixing process, the acid mist contains a large amount of acid, the acid has strong corrosiveness, the skin is injured by contact with the mist, people in the mist need to breathe inevitably, the smoke mist is corroded to burn the tracheopharynges and the lung lobes, the upper respiratory tract irritation symptoms can be caused by the inhalation of the acid mist, the skin contact causes burn, conjunctivitis edema and corneal turbidity are caused by the splash into eyes, the physical health of operators is seriously threatened, the generated acid mist is not controlled, the environmental pollution is not small, and a relevant device for fuming the waste acid pretreatment is not found.
Disclosure of Invention
The utility model aims to solve the problems of health damage and environmental pollution caused by acid mist in the waste acid mixing treatment process, and provides a fuming waste acid pretreatment device which can effectively avoid the acid mist from contacting operators and can carry out harmless treatment on the generated acid mist.
The utility model solves the technical problems by adopting the technical scheme that: the utility model provides a waste acid preprocessing device that fuming, contains waste acid mixing chamber and spraying system, waste acid mixing chamber side is equipped with sealing door, observation window and operation gloves, and waste acid mixing chamber bottom is equipped with the collecting channel, and spraying system mainly comprises spray pipe network, shower nozzle, water pump and sodium hydroxide solution case, and the shower nozzle distributes on the spray pipe network, and spray pipe network passes through pipeline and water pump intercommunication, and the water pump passes through pipeline and sodium hydroxide solution case intercommunication, and spray pipe network setting is at the top of waste acid mixing chamber.
Optionally, an automatic wiper plate is arranged on the observation window.
Optionally, a discharge pipe is arranged at the bottom of the collecting groove, and an outlet of the discharge pipe is positioned outside the waste acid mixing chamber.
Optionally, the sodium hydroxide solution tank is provided with a stirrer.
The mode and the principle of the utility model are as follows: when the waste acid pretreatment device is used, an operator puts recovered small-bottle waste acid, small-barrel waste acid and a containing container into a waste acid mixing chamber through a sealing door of the waste acid mixing chamber, then the operator walks out of the waste acid mixing chamber, the sealing door is closed, a water pump is started, a spray head sprays a dense dilute sodium hydroxide solution into the waste acid mixing chamber, the operator stands outside the waste acid mixing chamber, the small-bottle waste acid and the small-barrel waste acid are poured into the containing container through an operation glove and an observation window, acid mist generated in the pouring process and the dilute sodium hydroxide solution diffused in the waste acid mixing chamber are subjected to neutralization reaction, the neutralized liquid is gathered in a collecting ditch and then is discharged outside the waste acid mixing chamber through a discharge pipe, after the waste acid mixing chamber is free of acid mist, the operator continues to put the small-bottle waste acid and the small-barrel waste acid into the waste acid mixing chamber, and after the waste liquid of the containing container reaches a certain liquid level, the waste liquid is conveyed into a reaction kettle for reaction, and the pretreatment of the waste acid is completed.
Compared with the prior art, the utility model has the following beneficial effects: the utility model can effectively avoid the acid mist from contacting operators, and can carry out innocent treatment on the generated acid mist.
