A kind of treatment agent containing organic chlorine waste gas, preparation method and application thereof

Abstract

The invention provides a treatment agent for low-concentration organic chlorine-containing waste gas, a preparation method and its application. The treatment agent uses light calcium carbonate as a main Calcium sulfate, as a reinforcing agent, has high organochlorine hydrolysis activity and organic component combustion activity, and realizes dechlorination of organochlorine compounds and catalytic combustion of by-product chlorine-free organic components under temperature conditions such as 300-350°C, thereby The conversion of organic chlorine into calcium chloride, carbon dioxide and water is easy to achieve standard discharge, and the organic chlorine conversion capacity and dechlorination capacity of the treatment agent are not affected by the carbon dioxide contained in the exhaust gas; the raw materials used in the dechlorination agent are cheap, and the dechlorination The cost of the agent is low, it is basically non-toxic after use, and it is easy to be scrapped and disposed of. The treatment agent containing organic chlorine waste gas of the present invention, in terms of parts by mass and water-free matter, consists of 60-80 parts of light calcium carbonate, 10-15 parts of ferrous sulfate, 5-10 parts of manganese sulfate, and 5 parts of metatitanic acid ‑15 servings of ingredients.

Description

technical field [0001] The invention belongs to the technical field of treatment of organic chlorine-containing waste gas, and particularly relates to a treatment agent, preparation method and application of organic chlorine-containing waste gas. Background technique [0002] Chlorine-containing organic compounds, also known as organochlorines, are a class of important industrial raw materials, such as chlorinated alkanes and chlorinated aromatic hydrocarbons, which are widely used as raw materials for chemical reactions, solvents, or additives for many processing aids; Degradability and toxicity, organic chlorine in waste gas, waste liquid and waste must be properly treated, transformed and removed before it can be discharged, disposed of or landfilled; the treatment of waste gas organic chlorine is the most important technical field, because waste liquid, The organic chlorine in the waste is driven into the waste gas by stripping and thermal volatilization for further trea...

Problems solved by technology

[0004] For chlorine such as 500mg / m 3 The common waste gas containing organic chlorine is treated at 250-400°C by using calcium oxide as the main component and adding iron, manganese, copper and other oxides. It is more convenient and easy in many cases. Chlorine in chlorine is transformed into calcium chloride and is trapped in the dechlorination agent, but chlorine-free organic matter generally still exists in the exhaust gas after treatment. When the chlorine-free organic matter exceeds the standard, it still cannot be discharged up to the standard, or further treatment is required to meet the standard emissions; and when the exhaust gas contains carbon dioxide, it will convert calcium oxide into non-alkaline calcium carbonate, or absorb carbon dioxide in long-term storage, resulting in a decrease in the organic chlorine conversion capacity and dechlorination capacity of the dechlorination agent.

Some copper-containing dechlorination agents may also lead to the production of higher chlorinated organochlorines or increase the complexity of organochlorines
