Composite efficient ammonia water atmospheric treatment agent and preparation method thereof

Abstract

The invention discloses a composite efficient ammonia water atmospheric treatment agent which comprises the following raw materials in parts by weight: 30-40 parts of silica gel, 20-30 parts of ammonia water, 5-15 parts of linolenic acid, 5-10 parts of a silane coupling agent, 3-5 parts of trehalose, 1-5 parts of sodium lignin sulfonate, 1-5 parts of hexadecyl sodium sulfonate, 1-3 parts of hydrazine hydrate and 1-3 parts of carbohydrazide. The preparation method comprises the steps: adding silica gel into absolute ethyl alcohol, heating, stirring, adding linolenic acid and the silane couplingagent, naturally cooling, filtering, and sealing at low temperature to obtain modified silica gel; and adding the modified silica gel into water, heating, keeping the temperature constant, adding linolenic acid, adding trehalose, sodium lignin sulfonate, sodium hexadecyl sulfonate, hydrazine hydrate and carbohydrazide, naturally cooling, and adding ammonia water to obtain the product. According to the invention, various pollutants in the flue gas can be treated at the same time, and the treatment agent is simple in production process, low in cost and suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of air pollution control, and in particular relates to a compound high-efficiency ammonia water atmospheric treatment agent and a preparation method thereof. Background technique [0002] Air pollution is a phenomenon in which certain substances enter the atmosphere due to human activities or natural processes, exhibiting sufficient concentrations for a sufficient period of time, and thus endangering the comfort, health and welfare of the human body or the environment. Air pollutants mainly include aerosol state pollutants and gaseous state pollutants. Aerosol state pollutants mainly include dust, smoke droplets, fog, dustfall, floating dust, suspended solids, etc.; gaseous state pollutants mainly include sulfur oxides dominated by sulfur dioxide, nitrogen oxides dominated by nitrogen dioxide, and Carbon monoxide-based hydrocarbons and hydrocarbons combined with carbon and hydrogen are mostly from the exhau...

AI Technical Summary

Problems solved by technology

Aerosol state pollutants mainly include dust, smoke droplets, fog, falling dust, floating dust, suspended solids, etc.; gaseous state pollutants mainly include sulfur oxides mainly composed of sulfur dioxide, nitrogen oxides mainly composed of nitrogen dioxide, and Carbon monoxide-based carbon oxides and carbon-hydrogen-combined hydrocarbons, most of them come from the exhaust gas emitted by factories, or the exhaust gas produced by burning fuel such as automobiles; at the same time, with the rapid development of cities in recent years, the generated A large amount of waste is mostly treated by incineration, but the process of waste incineration will produce acid gases including hydrogen chloride, hydrogen fluoride, nitrogen oxides, sulfur dioxide and other gaseous heavy metals such as mercury, as well as dioxins / furans, chlorophenols, polycyclic aromatic hydrocarbons, etc. Highly toxic organic substances further aggravate the pollution of the atmosphere

However, the treatment agents currently used for air pollution mainly include desulfurizers, denitrification agents, etc., and there are few treatment agents that can effectively treat highly toxic organic substances such as dioxins, and there is a lack of effective treatment of sulfur oxides, nitrogen oxides, and dioxins at the same time.
