Embodiment Construction

[0011] A dehydrogen sulfide modified activated carbon, made of the following raw materials in parts by weight (kg): 110-120 activated carbon, 15-20 copper sulfate, 8-10 zeolite, 8-10 diatomite, 5-7 activated alumina , orange peel 20-25, nano-scale silicon dioxide 2-4, copper oxide superfine powder 3-5, modified diatomite 4-5, appropriate amount of water;

[0012] The modified diatomite is made of the following raw materials in parts by weight (kg): diatomite 125, sepiolite 11, nano-carbon 1.5, clove oil 2.5 ascorbic acid 1.5, sodium alginate 2.6, kaolin 33, gynostemma powder 3.5 The preparation method is to put diatomite and sepiolite into a calciner and calcinate at 550°C for 3.5 hours, take it out, soak it in 14% hydrochloric acid solution for 4 hours, filter it out, wash it repeatedly with clear water, and dry it. Add water, at the same time, add nano-carbon, ascorbic acid, kaolin, grind to obtain slurry, spray dry, mix other remaining ingredients with dry powder, grind and...

Abstract

The invention relates to hydrogen-sulfide-removed modified active carbon, which is prepared from the following raw materials in parts by weight: 110 to 120 parts of active carbon, 15 to 20 parts of copper sulfate, 8 to 10 parts of zeolite, 8 to 10 parts of diatomite, 5 to 7 parts of active aluminum oxide, 20 to 25 parts of orange peel, 2 to 4 parts of nanometer silicon dioxide, 3 to 5 parts of copper oxide superfine powder, 4 to 5 parts of modified diatomite and an appropriate amount of water. The copper sulfate is used for modifying the active carbon, so that hydrogen sulfide can be rapidly removed; due to use of zeolite, modified diatomite, active aluminum dioxide, copper oxide superfine powder and the like, the effects of rapidly desulphurizing, absorbing bacteria and deodorizing can be realized; and since the orange peel is used as a material of the active carbon, the produced active carbon has a large pore size, high adsorption capability and reduced cost, is suitable for the livestock farm and can be used for purifying automobile exhaust.

Description

technical field [0001] The invention relates to the field of modified functional materials, in particular to a hydrogen sulfide-deactivated modified activated carbon and a preparation method thereof. Background technique [0002] With the development of science and technology and the gradual construction of modern industries, various chemicals have been developed and utilized, which has brought convenience to people's lives. The problem. [0003] At present, the pollutants in the air are mainly the gas produced by industrial fuel combustion, automobile exhaust, and toxic and harmful gases produced in production. Water pollution is mainly due to the fact that the sewage discharged from industrial production contains a large amount of toxic substances, and the sewage produced in people's daily life produces many harmful substances. There are many times in people’s lives that people need to remove toxins. For example, there are many bacteria and toxins on the filter screen of...
