  • Patent number: 10357742
    Abstract: The present invention relates to a method for inhibiting the formation of dioxin-like compounds in solid waste incineration flue gases, belonging to the field of cleaning of solid waste incineration flue gases. In accordance with the present invention, when incineration flue gases cool down to 500˜450° C., the flue gases are introduced into an inhibition reactor where copper chlorides in flue gas particulates mix and react with inhibitors to convert into copper metaphosphate so as to inactivate the copper chlorides which can catalyze the formation of dioxin-like compounds and control dioxin-like compound pollutants in incineration flue gases at the source. Compared with the prior art, the invention can effectively control the main formation ways of dioxin-like compounds in solid waste incineration flue gases by optimizing inhibitors and reaction conditions.

  • Patent number: 10358347
    Abstract: The present invention provides a safe, disposable and biodegradable chlorine dioxide micro generator that uses water soluble paper and hydrogel or compressed cellulose encased in filter paper pouch. The chemicals are kept in a stabilize form until activated by the addition of water. Multiple levels of protection against early exposure to water such as a foil pouch and an impermeable outer container allow for the safe transportation and storage in small, ready for deployment amounts of the chemicals. Water permeated the chemical pack housing and dissolves the paper walls of the chemical pouch housing and then the water facilitates the reaction between the acid and the sodium chlorite to form chlorine dioxide gas as will be described further hereunder. Absorbent and permeable materials packaged around the chemicals provide for the safe containment of the chlorine dioxide solution, and the expeditious aeration and release of the chlorine dioxide gas, once the chemical reaction has been completed.
