Embodiment Construction

[0040] figure 1 It is a figure which shows the structure of the incinerator 1 which concerns on one Embodiment of this invention. The incineration facility 1 is a facility for incinerating waste such as municipal garbage. The incineration facility 1 includes a combustion chamber 2 , a flue 3 , an exhaust gas treatment device 4 , a guide fan 51 , and a chimney 52 . Combustion of garbage and combustion of combustible gas generated from the garbage are carried out in the combustion chamber 2 . The flue 3 connects the combustion chamber 2 with the chimney 52 . The exhaust gas treatment device 4 and the guide fan 51 are arranged in the flue 3 . The guide fan 51 discharges the exhaust gas (combustion gas) generated in the combustion chamber 2 to the flue 3 and guides it to the chimney 52 through the exhaust gas treatment device 4 . That is, the exhaust gas generated from the combustion chamber 2 flows from the combustion chamber 2 toward the chimney 52 in the flue 3 , and the ex...

Abstract

The invention provides waste gas treatment device and incineration equipment. The exhaust gas treatment device (4) includes: a dust collector (43), which is arranged in the flue (3) through which the exhaust gas circulates; The chemical supply position (P1) between (43) supplies the waste gas treatment chemical; the dust collection ash conveying part (44) transports the dust collection dust collected by the dust collector (43) along the auxiliary pipe (3) different from that of the flue (3). The path (441) is transported to the dust collection ash supply position (P2) between the combustion chamber (2) and the dust collector (43) in the flue (3); and the dust collection ash heating part is arranged on the auxiliary path ( 441), for heating dust collection ash. Thereby, adhesion of collected dust in the auxiliary path (441) can be suppressed.

Description

technical field [0001] The invention relates to waste gas treatment device and incineration equipment. Background technique [0002] Conventionally, general waste such as municipal waste was incinerated by waste incineration facilities. Exhaust gas generated by incineration contains harmful substances such as coal dust, hydrogen chloride (HCl), sulfur oxides (SOx), nitrogen oxides (NOx), and heavy metals (Pb, Hg, etc.). Therefore, the above-mentioned harmful substances are removed from the exhaust gas by the exhaust gas treatment device, and the treated exhaust gas is discharged to the atmosphere. [0003] For example, Japanese Patent Laying-Open No. Sho 59-150525 (Document 1) discloses the following method: in the process of removing harmful acid gas components such as hydrogen chloride from the waste gas by blowing hydrated lime powder into the waste gas, by collecting dust A part of the dust collected by the filter is pulverized and sent to the flue by the air blower, s...
