Abstract
The invention relates to a process of treating hazardous wastes and waste acids capable of violently reacting with water. The process can reduce the contact of operating staff with acids and control the concentration of acid gas generated during the dissolution and dilution procedures in the treatment of hazardous wastes and waste acids, can effectively absorb the generated acid gas to eliminate risk factors, and can safely and effectively treat the hazardous wastes and waste acids capable of violently reacting with water in an environment-friendly manner without generating damage to human beings or secondary pollution to the environment.
Description
Technical field
The invention belongs to the waste treatment processes field, relate to the discarded sour treatment process of a kind of Hazardous wastes with the water vigorous reaction, being particularly useful for can be safely and effectively carrying out harmless treatment with the discarded acid of the Hazardous wastes of water vigorous reaction, can not produce harm, can not produce secondary pollution simultaneously environment to the people.
Background technology
In the process of using acid, can not normally use for various reasons, the long-term placement caused potential harm to personnel and environment etc., it is improper to store, as airtight not tight, and humidity etc., the capital reacts, produce acid gas, personnel, environment and equipment etc. are caused in various degree harm, need in time carry out harmless treatment.In treating processes,, need to handle behind the dilute with water because this acid concentration height can not directly be handled.In the process of dilute with water, very violent with water reaction, produce a large amount of acid gas, treatment people is caused very big harm, equipment is caused in various degree infringement, simultaneously environment is produced secondary pollution.
Summary of the invention
Problem to be solved by this invention is, overcome the deficiencies in the prior art, provide a kind of Hazardous wastes discarded sour treatment process with the water vigorous reaction, by this technical process, can reduce the contact of operator to acid, be controlled at the acid gas concentration that produces in the process of handling the discarded sour dissolved dilution of Hazardous wastes, can effectively absorb the acid gas that produces simultaneously, factor eliminates danger, can be safely and effectively carrying out harmless treatment with the discarded acid of the Hazardous wastes of water vigorous reaction, can not produce harm, can not produce secondary pollution simultaneously environment to the people.
The present invention solves its technical problem and takes following technical scheme to realize:
According to the discarded sour treatment process of a kind of Hazardous wastes with the water vigorous reaction provided by the invention, it may further comprise the steps:
Open discarded sour container, with extractor fan acid gas is absorbed tourie, the negative pressure of utilizing vacuum pump to produce simultaneously is transported to feed pot to discarded acid;
Feed pot is in sealed state, and evacuated tube inserts extractor fan, passes through extractor fan, the a small amount of acid gas that produces enters tourie, the by-pass valve control of may command flow is equipped with in the tourie bottom, and discarded sour flow control is at 30～80L/h, and discarded acid flows into retort by by-pass valve control;
The retort evacuated tube inserts extractor fan, puts into the diluent media water that is in flow state in jar, and unabsorbed a small amount of acid gas enters extractor fan by evacuated tube, and by extractor fan, acid gas enters tourie; After question response was finished, the liquid in the retort becomes did not have volatile acidic solution, entered treatment tank and carried out harmless treatment;
Tourie is put into alkaline liquid, spiral nozzle by ball valve and its control makes the alkaline liquid atomizing, in the tourie polypropylene Pall ring filler that accounts for tourie 1/5～1/6 volume is housed simultaneously, is beneficial to the absorption to acid gas, tourie is equipped with the pH value automatic feedback system, guarantee that the liquid in the tourie is in alkalescence, if pH value is lower than 9, can replenishes alkaline liquid automatically and reach 12, after question response is finished to pH value, liquid in the tourie becomes alkaline salt solution, enters treatment tank and carries out harmless treatment;
The air quantity that blower fan produces makes entire treatment technology be in negative pressure state, and fan pressure is in 1～4KPa, and the blower fan outlet does not have acid gas to discharge.
The present invention compared with prior art has significant advantage and beneficial effect:
Because the technical process that invention is adopted, can reduce the contact of operator to acid, be controlled at the acid gas concentration that produces in the process of handling the discarded sour dissolved dilution of Hazardous wastes, can effectively absorb the acid gas that produces simultaneously, factor eliminates danger, can can not produce harm safely and effectively carrying out harmless treatment, can not produce secondary pollution simultaneously environment with the discarded acid of the Hazardous wastes of water vigorous reaction to the people.
The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is a process flow diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to embodiment provided by the invention, structure, feature and effect thereof, describe in detail as after.
The treatment process of the discarded acid of the Hazardous wastes of a kind of and water vigorous reaction as shown in Figure 1, it may further comprise the steps:
(1) container of unpacking, owing to contain aqueous vapor in the air, discarded acid reacts with water, has acid gas in the packing outlet and emerges.By extractor fan acid gas is absorbed tourie, directly be not discharged into atmosphere, can not produce secondary pollution environment.The negative pressure of utilizing vacuum pump to produce simultaneously is transported to feed pot to discarded acid.
(2) feed pot is in sealed state, and evacuated tube inserts extractor fan, and by extractor fan, a small amount of acid gas of generation enters tourie.The by-pass valve control of may command flow is equipped with in the tourie bottom, carries out Flow-rate adjustment as required, generally is controlled at 30～80L/h.Discarded acid flows into retort by by-pass valve control.
(3) the retort evacuated tube inserts extractor fan, puts into a certain amount of diluent media water in jar, allows it be in flow state, is beneficial to reaction and absorbs, and unabsorbed a small amount of acid gas enters extractor fan by evacuated tube.By extractor fan, acid gas enters tourie.After question response was finished, the liquid in the retort became certain density acid solution, entered treatment tank and carried out harmless treatment.
(4) tourie is diameter 1.2m, the container of high 5m, and the alkaline liquid of 1m is equipped with in the bottom, and the spiral nozzle of ball valve and its control is equipped with on top, and alkaline liquid circulates by pump, by spiral nozzle the time, makes the alkaline liquid atomizing.1.2m is equipped with at the place polypropylene Pall ring filler that accounts for tourie 1/5～1/6 volume below spiral nozzle, is beneficial to the absorption to acid gas.Tourie is equipped with the pH value automatic feedback system, guarantees that the liquid in the tourie is in alkalescence.If pH value is lower than 9, can replenishes alkaline liquid automatically and reach 12 to pH value.After question response was finished, the liquid in the tourie became certain density alkaline salt solution, entered treatment tank and carried out harmless treatment.
(5) air quantity of blower fan generation makes entire treatment technology be in negative pressure state.Fan pressure is in 1～4KPa, and air quantity is control effectively, and the blower fan outlet can not have acid gas to discharge.
Discarded acid in treatment tank becomes a kind of certain density volatile acidic solution that do not have that has, and can carry out harmless treatment according to the discarded acid treatment process of common Hazardous wastes.
