Detailed Description
In order to more clearly illustrate the utility model, the utility model is further described below with reference to preferred embodiments and the accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the utility model.
As shown in fig. 1, in the present embodiment, the incineration and waste heat recovery integrated incinerator includes a heat accumulating type incineration part 1 and a waste heat recovery part 2, an air outlet end of the heat accumulating type incineration part 1 is in fluid conduction connection with an air inlet end of the waste heat recovery part 2 through a heat insulation pipeline 3, and an air outlet end of the waste heat recovery part 2 is provided with a regulating valve 4.
In order to shorten the length of the heat insulation pipeline 3 between the heat accumulating type incineration part 1 and the waste heat recovery part 2 as much as possible, the air inlet end of the waste heat recovery part 2 is positioned at the upper end of the waste heat recovery part 2, the air outlet end of the waste heat recovery part 2 is positioned at the lower end of the waste heat recovery part 2, and the air outlet end of the waste heat recovery part 2 is in fluid conduction connection with the air inlet end of the chimney 5.
Because the waste gas discharged by the incinerator contains dust and some harmful substances, the dust and the harmful substances in the waste gas are required to be removed after the waste heat of the waste gas discharged by the incinerator is recovered, therefore, the spray header 6 which is in fluid conduction connection with the booster pump 8 is arranged on the inner walls of the middle section and the lower section of the chimney 5, the standing sedimentation tank 7 is arranged at the bottom of the chimney 5, the standing sedimentation tank 7 is in fluid conduction connection with the water storage tank 9, and the water storage tank 9 is in fluid conduction connection with the booster pump 8.
