Description

Technical Field

[0001] The utility model relates to the technical field of garbage incineration power generation, in particular to an air induction device for waste gas from garbage incineration. Background Art

[0002] Waste incineration is the process of reducing the volume of waste through oxidation at high temperature through appropriate thermal decomposition, combustion, melting and other reactions, and turning it into residue or molten solid matter. Waste incineration facilities must be equipped with flue gas treatment facilities to prevent heavy metals, organic pollutants, etc. from being discharged into the environmental medium again, and to recover the heat generated by waste incineration to achieve the purpose of waste resource utilization. However, a large amount of waste gas and smoke will be emitted during waste incineration, so a draft fan will be installed at the end of the incinerator to absorb it centrally for further treatment. However, the exhaust gas smoke generated after garbage incineration contains a large amount of particulate matter. Before entering the induced draft fan, a filter is used to filter it to prevent dust and various particulate matter from adhering to the blades and the inside of the induced draft fan. However, most of the existing filter nets are inserted into the air duct using a plug-in design. Each time the filter net is cleaned, it is necessary to pull the filter net out of the air duct and insert a clean filter net. However, since the content of particulate matter generated each time the garbage is incinerated is different, the timeliness of cleaning the filter net cannot be guaranteed, resulting in poor induced draft effect and failure to drain the exhaust gas in time. Based on this, the present application proposes an induced draft device for waste gas from garbage incineration, which is used to solve the above-mentioned problem. Utility Model Content
