A kind of activated carbon diatomite particles with developed pores and low cost and preparation method thereof

Abstract

The invention discloses activated carbon diatomite particles with well-developed pores and low cost. The activated carbon diatomite particles are characterized by being prepared from the following raw materials in parts by weight: 95-105 parts of fruit shell activated carbon, 30-35 parts of diatomite, 18-22 parts of traditional Chinese medicine residues, 22-26 parts of tung seed shells, 6-9 parts of kaoline, 1-2 parts of a silane coupling agent kh560, 3-4 parts of sodium sulfate, 4-6 parts of limestone powder, 2.5-3.5 parts of vitrified microspheres, 3.5-5 parts of silicon micro-powder, 3-5 parts of clay, 3-5 parts of active aluminum oxide, 4-6 parts of an absorbent additive and an appropriate amount of water. According to the method for preparing the activated carbon diatomite particles with the well-developed pores and the low cost, the materials such as the traditional Chinese medicine residues, and the tung seed shells are reused, dried, crushed and then added into the activated carbon and the diatomite, and the particles have sufficient sources of raw materials, the well-developed pores, the high absorption ability and the excellent property; the absorbent additive gives the special porosity of the particles and increases the contact time between gas and each particle; the particles prepared according to the method have the good desulfurization dedusting effect and the high porosity, and is low in cost and simple in production process, and therefore, the operation cost of dry desulfurization is greatly reduced.

Description

technical field [0001] The invention relates to a desulfurization activated carbon and a preparation method thereof, in particular to an activated carbon diatomite particle with well-developed pores and low cost and a preparation method thereof. Background technique [0002] With the rapid development of society, environmental pollution is also becoming more and more serious, industrial waste gas, automobile exhaust, etc. are seriously perplexing human life. There is a new understanding of the freshness of the air, and higher requirements for air purification capabilities. Among the many desulfurization methods, one is activated carbon adsorption. Although activated carbon can adsorb a variety of acid gases, the price of activated carbon is relatively high, and the desulfurization efficiency is low, which increases the cost. In the present invention, activated carbon is combined with diatomite with special pores, and various functional substances are added to make granular ...
