Problems solved by technology
[0004] However, when the production environment fluctuates, the concentration of hydrogen sulfide produced will also fluctuate, and in the above-mentioned treatment process to hydrogen sulfide, the amount of sodium sulfide solution sprayed and the concentration of sodium sulfide solution cannot be compared with the concentration of hydrogen sulfide As the concentration changes, some hydrogen sulfide will leak; at the same time, because sodium sulfide and hydrogen sulfide cannot completely and completely react, some hydrogen sulfide has not been absorbed and treated.
Untreated hydrogen sulfide in flue gas will cause environmental pollution and bring great harm to operators

The invention discloses a method for eliminating hydrogen sulfide in flue gas. The method comprises the steps as follows: firstly, utilizing sodium sulfide to absorb hydrogen sulfide in the flue gas so as to obtain preliminarily purified flue gas, and then utilizing neutral or alkali absorption media to process the preliminarily purified flue gas so as to obtain the purified flue gas. Through the utilization of the method provided by the invention, based on that the sodium sulfide is utilized to absorb the hydrogen sulfide at present, and the neutral or alkali absorption media are used for absorbing the hydrogen sulfide in the flue gas again, so that hydrogen sulfide contained in the flue gas is further eliminated, and the purpose of improving the hydrogen sulfide elimination effect is realized. The invention further provides a system for eliminating hydrogen sulfide in the flue gas, hydrogen sulfide in the flue gas is processed for many times through comprehensive utilization of sodium sulfide and absorption media, and through the circular processing method, the hydrogen sulfide elimination effect is further improved.
Description
technical field [0001] The invention relates to the technical field of waste gas treatment, more specifically, to a method for eliminating hydrogen sulfide in flue gas, and also to a system for eliminating hydrogen sulfide in flue gas. Background technique [0002] The flue gas containing sulfur dioxide in the acid making system (especially the flue gas acid making system) is also mixed with particulate matter and dust, and has a certain amount of heat. The pickling purification process is widely used in the industry to remove arsenic, fluorine and other heavy metal particles in the flue gas, that is, use dilute acid as the washing and purification liquid, and pass the flue gas into it to dissolve the arsenic, fluorine and other heavy metal particles into the cleaning solution. The purification efficiency of the pickling purification process is high, but during the treatment of this process, the sulfur ions in the washing and purification liquid will combine with hydrogen i...
