Problems solved by technology

[0005] At present, the dust inhibitor technology in China only considers the simple solution to the problem of dust diffusion, and has no other functions. The actual application is mainly in the dust and fly ash generated by urban roads and building construction.
For the cement production industry, there is no special dust inhibitor with the function of saving coal and reducing consumption.

Abstract

The invention discloses an energy-saving and environment-friendly flying dust suppressing agent specially for cement and a preparation method thereof. The energy-saving and environment-friendly flying dust suppressing agent is specially used for raw meal stored in a raw meal homogenizing silo of a cement production enterprise, and comprises the following components in percent by weight: 10%-20% of a decomposition-promoting component, 30-45% of a water-absorbing and moisturizing component, 5%-8% of a soaking and wetting component, 1%-4% of a stabilizing component and the balance of water. When the product is sprayed to a storage yard of the raw meal homogenizing silo, an obvious dust suppressing effect can be maintained in 30 days. The energy-saving and environment-friendly flying dust suppressing agent disclosed by the invention has the advantages that under the action of the decomposition-promoting component, when raw materials sprayed by the product are used for producing clinkers, the effect of reducing consumption of tailings can be realized, and economic values can be created for the cement production enterprise.

Description

technical field [0001] The invention belongs to the technical field of energy saving and environmental protection, and in particular relates to a dust inhibitor which can promote the decomposition of raw materials and reduce coal consumption. Background technique [0002] Cement production enterprises are recognized as heavy polluting enterprises. There are a lot of dust and fly ash in material transportation, material storage, production links, and product transportation. Especially for material storage, cement production involves many types of raw materials, which need to be homogenized in a large homogenization warehouse before use, and then stored in the yard for use. During the process, a large amount of powder will be mixed, and a large amount of dust will be generated at the same time. [0003] Dust inhibitors have been successfully applied abroad for more than 30 years. In recent years, my country has begun to pay attention to the damage of dust pollution to the en...
