Problems solved by technology

[0003] The applicant has previously applied for a series of patented technologies such as "a treatment process for flue gas produced in the amino acid preparation process" and "an environmental protection process for purifying tail gas from amino acid production", all of which use a combination of chemical agents and biological agents. For flue gas treatment, this method has a good treatment effect, but the preparation process of biological agents is relatively difficult, which is difficult for general enterprises to master, and the cost of components such as culture medium is relatively high, so it is difficult to be accepted by small and medium-sized enterprises

Embodiment 3

[0041] Simulated flue gas adsorption test:

[0042] Get respectively the preparation 20g prepared by embodiment 1 and embodiment 2 as experimental group 1 and experimental group 2, get activated carbon adsorbent 20g as contrast group, process flow is identical, as follows:

[0043] Place the sample in a reactor (30mm in diameter and 400mm in length), pass through simulated flue gas with a SO2 concentration of 1.5g / m3, and use a mass flow controller to control the flow of the flue gas; after 30 minutes, use a flue gas analyzer To measure the concentration of SO2, the formula is as follows: Adsorption rate=[1-(Outlet SO2 content×Outlet gas flow rate) / (Inlet SO2 content×Inlet gas flow rate)]×%. The same method was used to detect the adsorption rate of Nox, H2S and soot. The specific results are shown in Table 1:

Abstract

The invention belongs to the field of fume treatment and discloses a preparation for treating fume produced by amino acid production process. The raw materials of the preparation include silicone powder, sodium silicate, aluminum sulfate, peanut shells, kaolin clay, fly ash, polyacrylamide, straw, lignitous coal, zeolite powder and aqueous ammonia. The preparation has low material cost and fine absorption effect and is simple to prepare.

Description

technical field [0001] The invention belongs to the field of flue gas treatment, and in particular relates to a preparation for treating flue gas generated in an amino acid production process. Background technique [0002] In the amino acid production process, a large amount of boiler flue gas will be generated. Boiler flue gas is a mixture of gas and smoke, which is the main cause of air pollution in residential areas. The composition of the flue gas is very complex. The gas includes water vapor, sulfur dioxide, hydrocarbons, and nitrogen oxides. The smoke includes fuel ash, coal particles, oil droplets, and high-temperature cracking products. Therefore, the pollution of flue gas to the environment is the compound pollution of various poisons. The harmfulness of smoke to the human body is related to the size of the particles. The most harmful to the human body is the floating dust with a diameter of less than 10 microns, especially the 1-2.5 micron floating dust is the ...
