Research Of Lead And Zinc Smelting Gas Treatment By HSJ Organic Amine Desulfurization Technology

As countries of various industries in the production of atmospheric emissions standards to further improve, more and more enterprises in carrying on the transformation and upgrading of production facilities. ShuiKouShan nonferrous group, this paper intends to worthy projects- liquid high lead slag direct reduction project form a complete set of flue gas desulfurization system, energy saving and emission reduction for the tailor a set of atmospheric desulfurization technology, is used to implement the ShuiKouShan group pollution and emissions reduction targets, eliminate smoke emission pollution hazards,protect the regional ecological environment, realize the sustainable development of nonferrous group ShuiKouShan. Full text main content includes the following two aspects:The first point, renewable two suction one solution desulfurization process design.On the basis of flue gas conditions of refinery, by means of the limestone- gypsum method, alkaline sodium and renewable resource desulfurization method, technical and economic comparison of three kinds of process, summed up the renewable resource desulfurization method is the most suitable for flue gas desulfurization of refinery scheme.According to the actual situation of refinery, the appropriate improvements were made on the basis of the original process, put forward two suction a solution desulfurization process,and fully demonstrate the in process design. Combination process of waste heat utilization plan, anticorrosive, two suction a solution desulfurization technology is the best desulfurization scheme design in view of the existing conditions.Second, renewable desulfurization absorption liquid purification technology of experimental researchInvestigates the method of ion exchange resin absorption liquid to remove SO42- in effect, activated alumina particle removal effect of F- in the absorption solution and aluminum sulfate for venturi washing water fluoride in effect, the following main conclusions:(1) A, B and C resin for sulfate removal from the experiment show that for both the simulated wastewater and organic amine solution of fluorine ion and sulfate ion, C resin of anion ion exchange capacity has obvious advantages, in organic amine solution the ionexchange rate is as high as 86.71 mg/ml. Therefore, the project chooses C resin to remove the sulfuric acid root in the absorption solution.(2) activated alumina particles fluoride in experiment showed that the smaller the particle diameter of activated alumina, the fluorine ion, the better adsorption effect, effect of coexisting ions on the adsorption of organic amine liquid. Using NaOH regenerate activated alumina solution F- the adsorption efficiency of over 85%, NaOH regeneration effect at around 50%.(3) aluminum sulfate of fluoride in the experiment show that the effect of fluoride and solution related to the initial concentration of F-.The higher the initial concentration of F- in the solution, aluminum sulfate of fluoride in the better the results.Three, liquid high lead slag direct reduction of energy conservation and emissions reduction engineering supporting research on the performance of the flue gas desulfurization system projectThrough study on the performance of the project tracking, the results show that the system to achieve the desired effect, emissions in accordance with the relevant state standard.
