Abstract
The invention discloses a method for purifying acid mist from a pickling process, which is characterized in that: an acid mist recovery and purification device is arranged in a common pickling system; the device consists of an acid-resistance fan, a draft duct, a collecting barrel and a neutralizing tower; the draft duct is arranged above the picking system; the acid mist is led to the draft duct by the acid-resistance fan first and then is led to the collecting barrel; the picking liquid which is the condensate of the recovered acid mist is pumped by an acid-resistance pump into an acid tank in the pickling system; and the acid mist not condensed is absorbed into the neutralizing tower and absorbed by alkaline solution, so that no acid mist is discharged into the atmosphere. The method is economic and effective and can relieve environmental pollution.
Description
(1) technical field
The present invention relates to the purifying treatment method of acid mist in a kind of acid cleaning process.
(2) background technology
Pickling is a kind of the most frequently used method on clean metal surface, no matter is that low power to metal blank detects or to the surface derusting of metallic articles such as band steel.Pickle generally has the hot solution of sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid and hydrofluoric acid etc.The most general pickle of use is the hydrochloric acid solution after the heating at present.So acid mist is the inevitable outcome in the acid cleaning process, bring work under bad environment and air severe contamination thus.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide the purifying treatment method of acid mist in a kind of economy, the effective acid cleaning process, to reduce environmental pollution.
The object of the present invention is achieved like this: the purifying treatment method of acid mist in a kind of acid cleaning process, described method is to add acid mist reclaiming clean device in common pickling system, this device is by acidproof blower fan, the air inducing groove, collecting vessel and neutralizing tower are formed, the air inducing groove is placed described pickling system top, by acidproof blower fan acid mist is introduced the air inducing groove, import collecting vessel again, the pickle that is condensed into by acid mist that will reclaim with acid-proof pump pumps into the acid storage tank in the described pickling system, the acid mist that does not condense is sucked neutralizing tower, with in the alkaline solution and absorb, be not discharged into purpose in the atmosphere thereby reach acid mist.
The invention has the beneficial effects as follows:
The purifying treatment method economy of acid mist in the acid cleaning process of the present invention effectively, can reduce environmental pollution.
(4) description of drawings
Fig. 1 is the process chart of the purifying treatment method of acid mist in the acid cleaning process of the present invention.
(5) specific embodiment
Referring to Fig. 1, Fig. 1 is the process chart of the purifying treatment method of acid mist in the acid cleaning process of the present invention.As seen from Figure 1, the purifying treatment method of acid mist in a kind of acid cleaning process that the present invention relates to, described method is to add acid mist reclaiming clean device in common pickling system, this device is made up of acidproof blower fan, air inducing groove, collecting vessel and neutralizing tower, the air inducing groove is placed described pickling system top, by acidproof blower fan acid mist is introduced the air inducing groove, import collecting vessel again, the pickle that is condensed into by acid mist that will reclaim with acid-proof pump pumps into the acid storage tank in the described pickling system, the acid mist that does not condense is sucked neutralizing tower, use in the alkaline solution and absorption.
The material of described acidproof blower fan, air inducing groove, collecting vessel and neutralizing tower can be fiberglass, polyvinyl chloride, polypropylene, line plastic-steel tube or lining plastic-steel plate etc., consider that from the angle of ageing-resistant, high temperature resistant and economy and making, construction etc. glass-reinforced plastic material is optimal selection.
It can be soda bath that neutralizing tower absorbs the used alkaline solution of acid mist, or soda (sodium bicarbonate or dodium thiosulfate) solution, or other inorganic alkaline solution such as potassium hydroxide, generally with soda bath for commonly used, and do not have the carbon dioxide discharging.
Claims (1)
1. the purifying treatment method of acid mist in the acid cleaning process, it is characterized in that described method is to add acid mist reclaiming clean device in common pickling system, this device is made up of acidproof blower fan, air inducing groove, collecting vessel and neutralizing tower, the air inducing groove is placed described pickling system top, by acidproof blower fan acid mist is introduced the air inducing groove, import collecting vessel again, the pickle that is condensed into by acid mist that will reclaim with acid-proof pump pumps into the acid storage tank in the described pickling system, the acid mist that does not condense is sucked neutralizing tower, use in the alkaline solution and absorption.
