Problems solved by technology

[0005] The exhaust temperature range of industrial boilers is 120-300°C. Therefore, most of the existing flue gas desulfurization technologies cannot be directly used for the removal of sulfur dioxide in indoor air.
The desulfurization effect of attapulgite composite metal oxide desulfurizer is average, and the preparation process is complicated, and the initial desulfurization temperature is high

Abstract

The invention discloses a desulfurization agent. The desulfurization agent contains potassium permanganate and attapulgite. The desulfurization agent simultaneously has excellent adsorption performance of the attapulgite component and strong oxidizing property of the potassium permanganate component and further has very strong sulfur dioxide removal capacity. Compared with an existing desulfurization technique, the desulfurization agent is relatively suitable for purifying sulfur dioxide in indoor air. By introducing potassium permanganate with strong oxidizing property to directly oxidize sulfur dioxide into sulfate so as to realize normal temperature desulfuration, the reaction is rapid and efficient, and the sulfur dioxide removal efficiency is guaranteed; and the desulfurization agent has very good potential market values.

Description

technical field [0001] The invention relates to a desulfurizing agent, its preparation method and application, in particular to a desulfurizing agent for indoor air desulfurization, its preparation method and application. Background technique [0002] With the development of our country's economy, people pay more and more attention to environmental and health issues. Sulfur dioxide is a gas that seriously pollutes the air. It not only causes serious respiratory and cardiovascular diseases, but also is the main cause of acid rain, causing serious damage to buildings and causing economic losses of up to 15 billion yuan per year. All countries in the world have set strict emission standards for sulfur dioxide, so effectively controlling sulfur dioxide in the air has become an urgent research topic, and the development of desulfurization technology is an urgent problem to be solved in the field of environmental protection. [0003] The current desulfurization technology is main...
