Treating agent for removing sulfide from coking sewage volatile gas and treatment method thereof

Abstract

A treatment agent for removing sulfide in coking sewage volatile gas and a treatment method thereof, the formulation of the treatment agent is composed of alkali, sodium hypochlorite, cobalt sulfonated phthalocyanine as a catalyst and water, and the mixing ratio in the formulation is , alkali: sodium hypochlorite: cobalt sulfonated phthalocyanine: water=5000~7000: 1400~1600: 0.6~1.2: 8000~12000. Adopt the method for the sulfide in the coking sewage volatilization gas of above-mentioned treating agent, by the following steps: 3 The hourly gas flow rate is 300m 3 The reaction to remove hydrogen sulfide, methyl mercaptan and organic sulfur is carried out in a separate gas container; 2. Then, through laboratory tests, analyze the components of the gas before and after treatment, and discharge the gas that meets the emission standards into the atmosphere. The method has the advantages of simple formulation and convenient preparation of the treatment agent; simple operation of the method, high removal rate of hydrogen sulfide, and effective removal of methyl mercaptan and organic sulfur.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a treatment agent for removing sulfide in volatile gas of coking sewage and a treatment method thereof. Background technique [0002] An existing Chinese invention patent with application number CN201410792347.4 titled "Environmental Treatment Method for Waste Liquid Containing Caustic Soda Sodium Hypochlorite" discloses an environmentally friendly treatment method for waste liquid containing caustic soda sodium hypochlorite. When the NaOH solution absorbs chlorine waste gas, it will form Caustic soda sodium hypochlorite waste liquid, the above waste liquid is concentrated above 80°C, and NaClO is decomposed into NaCl and NaClO during the concentration process 3 , NaCl crystallizes out and is removed by filtration; the filtered caustic soda-containing waste liquid returns to continue to absorb chlorine waste gas, and the obtained waste liquid repeats the above-mention...
