As further improvement of the utility model, its 4th kind of embodiment is that it also includes hydrochloric acid tank and fortune acid Car, the first valve of hydrochloric acid tank is connected with the first entrance of acid fog absorption tower by pipeline, transports the second valve and the acid of sour car The first entrance on mist absorption tower is connected, and hydrochloric acid tank car sour with fortune is connected by magnetic drive pump.
As the improvement further of the retracting device of above-mentioned hydrochloric acid mist, the second entrance of acid fog absorption tower is provided with the 5th Valve.
As the improvement of above-mentioned second and the 4th kind of embodiment, acid-proof pump is also by the 4th valve and hydrochloric acid tank phase Even.
The acid mist of hydrochloric acid tank and fortune sour car volatilization is evacuated to acid fog absorption tower by pipeline;Logical inside acid fog absorption tower Cross the larger filler of setting specific surface area to strengthen the effect absorbing acid mist;Acid-proof pump be used for forced circulation tower in absorbing liquid and Product conveys;Vacuum pump provides for the acid mist in the system and evacuates power.
This utility model is highly soluble in the chemical property of water using hydrogen chloride, traps hydrochloric acid accumulating with industry water or pure water In journey, the hydrogen chloride gas of volatilization, can automatically control, repeatedly trap, concentration of hydrochloric acid to be trapped reaches setting value(This practicality is new Type produces 31% hydrochloric acid)Afterwards hydrochloric acid tank is delivered to by acid-proof pump, thus the hydrogen chloride of volatilization will not cause shadow to surrounding air Ring.
This utility model adopts the technique of " evacuation of packed absorber absorption+blower fan " and reclaims hydrochloric acid volatilization gas, technique Flow process is short, security performance is high.This device institute restored acid mist translates into hydrochloric acid product, has not only protected environment but also has efficiently reduced The waste of hydrochloric acid, makes enterprise achieve the purpose of energy-saving and emission-reduction, cost efficiency and resource recycling.
The cleared device of this utility model salt acid mist needs the acidity of regular sampling analysis absorbing liquid, in the stream ensureing circulation fluid On the premise of amount and acidity, the absorbance of salt acid mist can reach 97%, and emission is up to standard.
