Coal saving and fast burning agent and preparation method thereof

Abstract

The invention discloses a coal saving and fast burning agent. The coal saving and fast burning agent comprises 6-10wt% of diethanolisopropanolamine, 29-31wt% of glycerol, 6-8wt% of polymeric polyol, 11-13wt% of diethylenetriamine, 0.5-1.5wt% of hydroquinone, 0.5-1.5wt% of tripolyglycerol, 1.5-2.5wt% of ethylene glycol, 2.5-3.5wt% of sodium sulfite, 13-17wt% of barium nitrate, 0.5-1wt% of nanometer titanium oxide, and the balance of water. The coal saving and fast burning agent has the following advantages: 1, the output per machine hour of each of a raw mill and a coal mill is improved by above 15%, and the grinding power consumption is saved by above 15%; 2, the coal consumption in the cement production process is saved by above 10%; 3, the clinker output is improved by above 8%; 4, the strength of the clinker in each stage is improved by 2-5Mpa, and the clinker stability is improved; 5, the emission reduction of total content of CO2, SO3 and NO2 in cement production reaches above 8%; and 6, the comprehensive economic benefit of the clinker is improved by above 15yuan/t.

Description

technical field [0001] The invention belongs to cement raw meal additives, in particular to a coal-saving quick-burning agent and a preparation method thereof. Background technique [0002] Although the cement industry is an important industry in the national economy, it is also a big consumer of electricity and coal. In the previous cement shaft kiln production process, some cement plants used products such as "coal-saving agent" or "raw meal quick-burning agent". These products are mainly composed of mineralizers containing chloride salts or fluorine salts. To a certain extent, it can promote the calcination reaction of shaft kiln and reduce coal consumption. At present, the dry-process rotary kiln has replaced the vertical kiln with high energy consumption and low production efficiency, and this kind of mineralizer product is not suitable for the production of cement dry-process rotary kiln from the perspective of production technology, because this kind of product will ...
