Abstract
The utility model relates to a secondary-level acid mist absorbing and purifying device. The device comprises a primary acid mist absorbing tower and a secondary acid mist purifying tower, wherein an exhaust port is formed in the top end of each tower body, a padding area is arranged in the middle of each tower body, and a liquid storage area is arranged at the lower end of each tower body; a tap water inlet communicated with a shower head is formed in the top end of the primary acid mist absorbing tower; a dilute alkali inlet is communicated with the upper end of the secondary acid mist purifying tower through an alkali pump by a third shower pipe; and acid gas firstly recovered in the primary acid mist absorbing tower is sucked into an anti-corrosion fan through a pipeline, and then the pressurized acid gas is delivered to the secondary acid mist purifying tower for purification. The secondary acid mist absorbing and purifying device is reasonable in design and convenient to operate; tap water is adopted by the primary tower to absorb most part of acid mist, dilute alkali is adopted by the secondary tower to purify a small amount of acid gas, the absorption is complete, and meanwhile, generated dilute acid can be recycled; the cost is low and the waste is turned into wealth; and therefore, the secondary-level acid mist absorbing and purifying device conforms to the concept of modern environmental protection and governance. An adjustable valve is used for respectively adjusting the mixing ratio of the acid mist to air and the negative pressure in the primary acid mist absorbing tower, so that the absorption effect is improved and the volatilization amount of concentrated acid is reduced.
Description
Technical field
The utility model relates to a kind of secondary acid mist absorptive purifying device that can recycle and thoroughly purify.
Background technology
Due to need of production, medication chemistry class enterprise has stored a large amount of concentrated hydrochloric acids for allotment, dilution and standby.These concentrated acids constantly volatilize during storage and produce acid mist, and as untimely purified treatment, acid mist will cause heavy corrosion to equipment pipe and factory building facility etc., also pollute the environment simultaneously, jeopardize personal safety.
Traditional absorption technique adopts acid-base neutralization to process: blower fan is with acid mist sucking-off in the basin, and is emptying after the liquid caustic soda neutralisation treatment in the absorption tower.This technology liquid caustic soda consumption is many, and use cost is high, removes acid mist not thorough.
The utility model content
Existing above not enough for prior art, the utility model provides a kind of secondary acid mist absorptive purifying device.This plant area area is little, operating cost is low, the diluted acid recoverable after running water absorbs, and acid mist is removed thoroughly.The purpose of this utility model is to realize like this, a kind of secondary acid mist absorptive purifying device, comprise one-level acid fog absorption tower, secondary acid mist purifying tower, corrosive resistant fan, alkali pump, it is characterized in that: described one-level acid fog absorption tower, secondary acid mist purifying tower are cylindrical, two tower body tops are provided with exhaust outlet, the middle part is the packing area, and the lower end is the liquid storage district; One-level acid fog absorption tower top also is provided with running water inlet and communicates with shower nozzle; The diluted alkaline import is communicated with secondary acid mist purifying tower upper end by three grades of showers through alkali pump; Corrosive resistant fan purifies once reclaiming rear acid gas in the one-level acid fog absorption tower in the pipeline inhalation machine, being transported in the secondary acid mist purifying tower after pressurization.
The utility model is compared with traditional acid fog absorption tower, advantage be mainly reflected in following some:
1, the utility model is reasonable in design, easy to operate.First stage tower adopts running water to absorb most acid mist, and the secondary tower adopts diluted alkaline to purify a small amount of sour gas, absorbs thoroughly.
2, this secondary acid mist absorptive purifying device absorbs a large amount of acid mists, produced simultaneously diluted acid recoverable with running water.With low cost, turn waste into wealth; Meet modern environment protection treating theory.
3, this absorbing and purifying device arranges control valve, regulates respectively negative pressure in acid mist and air mixing ratio, first grade absorption tower.Improve assimilation effect, reduce the concentrated acid volatile quantity.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing;
A kind of secondary acid mist absorptive purifying device, comprise one-level acid fog absorption tower 2, secondary acid mist purifying tower 6, corrosive resistant fan 5, alkali pump 7, it is characterized in that: described one-level acid fog absorption tower 2, secondary acid mist purifying tower 6 are cylindrical, two tower body tops are provided with exhaust outlet, the middle part is the packing area, and the lower end is the liquid storage district; One-level acid fog absorption tower 2 tops also are provided with running water inlet 12 and communicate with shower nozzle; Diluted alkaline import 8 is communicated with secondary acid mist purifying tower 6 upper ends by three grades of showers 9 through alkali pump 7; Corrosive resistant fan 5 in pipeline 11 inhalation machines, is transported to the interior purification of secondary acid mist purifying tower 6 with acid gas after once reclaiming in the one-level acid fog absorption tower after pressurization.During concrete enforcement, the acid mist that 1 volatilization of hydrochloric acid basin produces flows to one-level acid fog absorption tower 2 through closed conduit, because one-level acid fog absorption tower 2 exhaust outlets are connected with corrosive resistant fan 5 inlet scoops, is micro-vacuum state in one-level acid fog absorption tower 2.The mist of acid mist and air is along with air-flow upwards flows.The running water inlet of one-level acid fog absorption tower 2 tower tops is connected with shower nozzle, and running water is sprayed onto whole Pall ring filler district through water-locator more equably after shower nozzle spray.Because hydrogen chloride gas is soluble in water, the acid mist over 70% is absorbed by water in the packing area; Remaining a small amount of acid mist and air are inhaled into corrosive resistant fan 5 together, be transported to secondary acid mist purifying tower 6 and continue to purify after supercharging.Secondary acid mist purifying tower 6 adopts the diluted alkaline purification of acidic gas.Alkali pump 7 outlet conduits are connected with three grades of showers 9, and the diluted alkaline that regularly injects evenly sprays the packing area by the water-locator of three grades of showers 9 and below, and the sour gas that concentration is lower purifies fully.During actual the use, the operative employee in time drains waste liquid, adds diluted alkaline, guarantees clean-up effect.The liquid that one-level acid fog absorption tower 2 spray-absorptions are crossed is faintly acid, is transported to tower top after acidproof water pump 3 superchargings, continues to absorb acid mist after evenly being distributed by water-locator; After circulation absorbs, the concentration of acid water improves constantly.When the concentration of acid water reaches certain value, open acidproof water pump 3 outlet stools, this dilute acid recycle is standby in the basin.One-level acid fog absorption tower 2 is adjustable air air inlet valve and fan induced draught valve in use.Regulate the air air inlet valve and can control the mixing ratio of air and acid mist, guarantee the acid mist assimilation effect; Regulate the fan induced draught valve and can control negative pressure in the tower on primary acids mist absorption tower 2, avoid negative pressure excessive and increase the volatile quantity of hydrochloric acid in the concentrated acid basin.
