Abstract
The invention relates to a method for collecting, purifying and processing ammonia exhaust gas, which belongs to the industrial exhaust-gas treatment technical field. The method is characterized in that a collection and purification device is provided over an ammonia exhaust gas generation area, the device is composed of a collection cover, an alkali resistance blower, a purification tower and an acid solution contact pool, a purification tower contains a spray apparatus, the collection cover is placed on the ammonia exhaust gas generation area, exhaust gas is introduced in the purification tower through the alkali resistance blower, then is introduced into the acid solution contact pool, and is neutralized and absorbed by an acidic solution and discharged after reaching the standard; liquid in the acid solution contact pool is introduced in the spray apparatus of the purification tower, exhaust gas introduced in the purification tower is carried out spraying, and then the method of the invention is performed circular treatment. The method for collecting, purifying and processing ammonia exhaust gas has the advantages of economy, effectiveness and environmental pollution reduction.
Description
Technical field
The present invention relates to a kind of collection and purification processing method of ammonia waste gas.Belong to the industrial waste gas processing technology field.
Background technology
Ammonia is a colourless gas, and the excitant foul smell is arranged.The aqueous solution is alkalescence, and the 0.1N aqueous ph value is 11.1.Be mainly used in and make nitric acid, explosive, synthetic fibers, chemical fertilizer; Also can be used as cold-producing medium.
Suck in a short time can occur shedding tears behind a large amount of ammonias, pharyngalgia, hoarseness, cough, sputum streaked with blood silk, uncomfortable in chest, expiratory dyspnea; Can be with dizzy, headache, feel sick, vomiting, weak etc.; Pulmonary edema, ARDS can take place in severe patient, simultaneously the respiratory tract symptom possibly take place.If the ammonia that sucks is too much, cause ammonia excessive concentration in the blood, will cause through the reflex of trigeminal neuralgia tip heart stop fight and breath stopped threat to life.
Long-term contact ammonia, symptoms such as skin pigment deposition or finger ulcer may appear in groups of people.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of collection and purification processing method of effective ammonia waste gas is provided, to reduce environmental pollution.
The objective of the invention is to realize like this: a kind of collection and purification processing method of ammonia waste gas, said method is provided with the collection and purification device above ammonia waste gas produces the zone, and this device is made up of collecting hood, alkaline-resisting blower fan, purifying column and acid solution contact chamber; Purifying column contains spray equipment, places ammonia waste gas to produce the top, zone collecting hood, through alkaline-resisting blower fan waste gas is introduced purifying column; Import the acid solution contact chamber again; With in the acid solution and absorb back emptying up to standard
FromBe not discharged into the purpose in the atmosphere and reach ammonia waste gas.Liquid with advancing in the acid solution contact chamber inserts the spray equipment in the purifying column, the waste gas that imports in the purifying column is sprayed, so circular treatment.
The invention has the beneficial effects as follows:
The collection and purification processing method economy of ammonia waste gas of the present invention, effective can reduce environmental pollution.

The specific embodiment
Referring to Fig. 1, Fig. 1 is the process chart of the collection and purification processing method of ammonia waste gas of the present invention.Can find out by Fig. 1, the collection and purification processing method of a kind of ammonia waste gas that the present invention relates to, said method is provided with the collection and purification device above ammonia waste gas produces the zone; This device is made up of collecting hood, alkaline-resisting blower fan, purifying column (containing spray equipment) and acid solution contact chamber; Place ammonia waste gas to produce the top, zone collecting hood, waste gas is introduced purifying column, import the acid solution contact chamber again through alkaline-resisting blower fan; With in the alkaline solution and absorb back emptying up to standard; Liquid in the acid solution contact chamber inserts the spray equipment in the purifying column, waste gas is sprayed, so circular treatment.
Said collecting hood and alkaline-resisting blower fan; Material can be 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, environment for use etc. polyvinyl chloride, polypropylene material are optimal selections.
The material of said purifying column and acid solution contact chamber can be 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 and environment for use etc. polyvinyl chloride, polypropylene material are optimal selections.
It can be hydrochloric acid solution that the acid solution contact chamber absorbs the used acid solution of ammonia waste gas, or sulfuric acid, salpeter solution, or other organic acidity solution such as acetic acid, generally with hydrochloric acid, sulfuric acid solution for commonly used.
