Embodiment Construction

[0023] The structure and working method of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] The present invention utilizes the now mature metallurgical sintering production equipment, and transforms it on the basis to form such figure 1 The solid waste incineration system shown has a high-temperature waste gas secondary combustion dry point device, and the system includes an incineration device and an exhaust system. The incineration device includes a cloth section 1 at the front, a drying section 2, an ignition section 3, and an incineration section 4 at the rear. The drying section 2 and the ignition section 3 are realized by a waste gas secondary combustion dry ignition device 6 . The waste gas secondary combustion dry ignition device 6 is obtained by reforming the igniter of the current sintering machine. It is in the form of a hood that is placed over the incinerated material, see figure 2 and image 3 , th...

Abstract

The invention discloses a solid waste incineration system with an exhaust gas secondary combustion drying ignition device and a treatment method thereof. The solid waste incineration system comprises an incineration device and an air extraction system, wherein the incineration device comprises a cloth section, a drying section, an ignition section and an incineration section; operation at the drying section and the ignition section is achieved through the exhaust gas secondary combustion drying ignition device; the exhaust gas secondary combustion drying ignition device is in a cover body form, covers sintering materials, and is divided into an exhaust gas secondary combustion drying part at the front section and an ignition part arranged at the tail end; the incineration exhaust gas returns to the ignition device and burns in the situation that gas fuel is externally added, and a secondary combustion chamber is formed; and combustible matters in the flue gas are completely combusted, and harmful substances such as CO, NOx and dioxin in the flue gas are decomposed and are effectively treated. According to the solid waste incineration system, a high temperature gas generated during combustion ignites the materials, and waste heat of the exhaust gas dries and preheats the materials before ignition.

Description

technical field [0001] The invention belongs to the solid waste incineration treatment technology, and in particular relates to the technology for treating flue gas after general solid waste and hazardous waste are incinerated. Background technique [0002] Solid waste refers to the solid and muddy substances discarded by humans in production and living activities, referred to as solid waste, which also includes solid particles separated from waste water and waste gas. Solid waste has a wide range of sources, various types, and complex composition. The hazards of solid waste to the human environment mainly include land occupation, soil pollution, water pollution, air pollution, and environmental sanitation. [0003] Since the composition of solid waste is extremely complex and contains a variety of pollutants, such as heavy metals, waste plastics, waste wood, etc., many chemical reactions will occur during the incineration process. In addition to excessive air and carbon di...
