Embodiment Construction

[0059] Preferred embodiments of the present invention will be described below with reference to the drawings. figure 1 It is an overall system diagram of the waste disposal facility 100 of the first embodiment and the cement manufacturing facility 200 installed adjacent thereto. figure 1 The waste treatment facility 100 shown on the left side of the center thermally decomposes waste in the gasification furnace 1 and uses the generated gas (pyrolysis gas) for mixed combustion in the cement firing process. The amount of the pyrolysis gas is, for example, 20,000 to 30,000 Nm 3 / h, and the exhaust gas volume of the cement manufacturing equipment shown in the figure 200 (for example, 300,000 Nm 3 / h) is much less, so the waste treatment plant 100 can be built next to an existing cement plant with little or no modification to the existing cement plant.

Abstract

The invention provides treating equipment for waste containing sludge. The objective of the invention is that the temperature of a fluid bed (1a) in a fluid bed gasification furnace (1) used for thermal decomposition of waste can be maintained in a proper range even when considerable waste containing high water content dehydrated sludge is treated. To realize the objective, treating equipment (100) for waste containing sludge is constructed beside cement manufacturing equipment (200). The treating equipment for waste comprises the fluid bed gasification furnace (1) which enables waste to be gasified for production of thermal decomposition gas, a gas delivery line (6) which delivers the produced thermal decomposition gas together with charcoal and ash to between a cement preheater (10) anda decomposing furnace (20), and heating devices like a waste gas air heater (41) which enables the temperature of fluidized air supplied to the gasification furnace (1) to rise by using waste heat ofthe cement manufacturing equipment (200).

Description

technical field [0001] The present invention relates to equipment for the hygienic disposal of waste using cement manufacturing equipment, and more particularly to the treatment of waste containing sludge with a high moisture content. Background technique [0002] In recent years, along with the improvement of living standards in developing countries, for example, there is an increasing need for sanitary disposal of waste, and an increase in the amount of waste incineration is also expected. However, there is also the problem that the construction of a general waste incinerator requires a large cost and a long construction period. Furthermore, in Japan there is still a shortage of landfill disposal sites for burying ash generated by calciners. When establishing a new waste disposal site, installation of ash melting furnaces and establishment of ash recycling methods are necessary conditions. [0003] In response to this, the inventors of the present application have develop...
