Embodiment Construction

[0013] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0014] Such as figure 1 As shown, the hazardous waste incinerator system usually includes several parts such as waste pretreatment system, feeding system, incineration system, and flue gas purification treatment system. The waste pretreatment system includes waste pretreatment and feeding procedures. Industrial hazardous waste is transported to the warehouse of the disposal center by special vehicles. The materials that need to be crushed are crushed by the crusher, and after compatibility, they are transported to the kiln head on the operation platform by the crane. The feed port is sent to the rotary kiln 2 by the hydraulic pusher device 1 after the feed port of the kiln head passes through the two-stage hydraulic sliding door.

[0015] The incineration system consists of a rotary kiln 2, a second combustion chamber 3, slag discharge an...

Abstract

The invention discloses a dioxin treatment system of a hazardous waste incineration furnace. The dioxin treatment system comprises a pretreatment system, an incineration system and a smoke purification system. The incineration system comprises a rotary kiln and a secondary combustion chamber. A dry reactor is arranged between a smoke outlet of a quench tower and a bag type dust collector of the smoke purification system, and lime activated carbon is jet in the dry reactor. A plasma dioxin removing tower is arranged behind the bag type dust collector. An activated carbon powder adding device is arranged in a circulating pond, and water mixed with activated carbon powder enters a wet deacidification tower to be sprayed. Multiple equipment and process controlling points are set in the whole hazardous waste incineration furnace, dioxin type substances are effectively adsorbed and controlled, and it is ensured that tail gas emission meets the standard. The dioxin treatment system is good in treatment effect, wide in treatment range, good in universality, high in treatment depth and high in operation stability and impact resistance, and the treatment effect is good in winter and summer.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a dioxin treatment system for hazardous waste incinerators. Background technique [0002] Dioxin is a colorless, odorless, highly toxic fat-soluble substance, and is a class of highly toxic substances. The sources of dioxins in the atmospheric environment are complex. Iron and steel smelting, non-ferrous metal smelting, automobile exhaust, incineration production (including medical wastewater incineration, chemical plant waste incineration, domestic waste incineration, coal-fired power plants, etc.) will produce dioxins. Among them, the mechanism of dioxins produced by incineration of hazardous waste is relatively complex, and thus has received the most attention. Existing hazardous waste incinerators do less dioxin treatment or use a single device to deal with dioxin, so they cannot meet environmental protection requirements.
