Problems solved by technology

In today's highly developed industry, coal is one of the most important energy sources. In cities and surrounding areas where power plants, industrial boilers and commercial boilers are highly concentrated, due to the low thermal efficiency of coal-fired boilers, the combustion equipment cannot burn all the fuel supplied to it. , the unburned fuel carries harmful substances such as sulfur and nitrate, and is discharged along with the smoke. The black smoke and waste residue cause environmental pollution and cause energy loss. At the same time, due to insufficient combustion, a large amount of dust will ac

Abstract

The invention discloses a high-efficiency environmental-friendly coal-saving sulphur-fixing antismoke agent and a production technology thereof. The high-efficiency environmental-friendly coal-savingsulphur-fixing antismoke agent comprises the following components in percentages by weight: 18%-22% of the sulphur-fixing agent, 18%-22% of the combustion improver, 22.5%-27.5% of the oxidizing agent,4%-6% of the swelling agent, 2%-3.5% of the catalyst, 3%-5.5% of the antismoke agent, 2%-5% of the hydrogen peroxide and the balance of water. The invention also provides the production technology ofthe high-efficiency environmental-friendly coal-saving sulphur-fixing antismoke agent. The obtained high-efficiency environmental-friendly coal-saving sulphur-fixing antismoke agent has convenient use and good sulphur-fixing and denitration effect, can eliminate partial smoke dust without generating secondary pollution, has low operation cost and outstanding coal consumption saving and can also enhance the heat efficiency of a boiler, thereby playing a positive role on reducing the atmospheric pollution of cities and saving energy sources.

Description

technical field [0001] The invention relates to a treatment agent for saving coal and a preparation method thereof, in particular to a high-efficiency, environment-friendly, coal-saving, sulfur-fixing and smoke suppressant and a production process thereof. Background technique [0002] At present, the problem of energy shortage is testing the development of economy. Once energy is in short supply, it will become a bottleneck restricting economic development. In today's highly developed industry, coal is one of the most important energy sources. In cities and surrounding areas where power plants, industrial boilers and commercial boilers are highly concentrated, due to the low thermal efficiency of coal-fired boilers, the combustion equipment cannot burn all the fuel supplied to it. , the unburned fuel carries harmful substances such as sulfur and nitrate, and is discharged along with the smoke. The black smoke and waste residue cause environmental pollution and cause energy ...
