Low-cost activated carbon kieselguhr particles with developed pores, and preparation method of kieselguhr particles

Abstract

The invention discloses low-cost activated carbon kieselguhr particles with developed pores. The activated carbon kieselguhr particles are characterized by being prepared from the following raw materials in parts by weight: 95-105 parts of nut shell activated carbon, 30-35 parts of kieselguhr, 18-22 parts of Chinese medicine residue, 22-26 parts of tung shell, 6-9 parts of kaolin, 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 glass beads, 3.5-5 parts of silica powder, 3-5 parts of clay, 3-5 parts of activated aluminum oxide, 4-6 parts of an absorption auxiliary agent and a proper amount of water. According to the activated carbon kieselguhr particles, the resources such as Chinese medicine residue, tung shell are reused and are fed into the activated carbon and the kieselguhr after being dried and ground; the activated carbon kieselguhr particles are sufficient in raw materials, developed in pores, high in absorption and excellent in performances; the absorption auxiliary agent is fed into the activated carbon kieselguhr particles, so that the activated carbon kieselguhr particles have special porosity, and the contact time of the activated carbon kieselguhr particles with air can be prolonged; the activated carbon kieselguhr particles have good desulfurization and dust-removal effects, are high in porosity, low in cost and simple in production technology, and are capable of greatly lowering the operating cost of dry desulfurization.

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 ...
