Embodiment Construction

[0016] With reference to the accompanying drawings: design a special circulating fluidized bed combustion boiler 1 that can burn coal gangue and municipal solid waste. Water pipes are arranged around the body of the boiler to heat water to generate steam. A steam pipeline 2 is provided, and a steam generator 4 is connected to the outlet end of the steam pipeline, and the electric output end of the generator is connected with the power supply network 3 in the enterprise to supply the electric energy of the system; the waste gas output end of the steam generator is connected to the The water gas generator 5 is connected to each other. The water gas generator uses steam to react with coal to generate water gas, which is transported to the gas input end of the ceramic body kiln 6 through pipelines. When the water gas burns, the pressed ceramic bricks are fired and molded. There is a furnace bridge in the fluidized bed boiler, under which there is a slag storage room for coal gangue...

Abstract

The system for producing ceramic tile with coal gangue and domestic garbage consists of boiler, steam driven generator, pulverizer, spray tower, pressure molding machine, kiln and pipeline. The present invention features the special fluidized bed boiler burning coal gangue and domestic garbage, the generator driven with steam the boiler produces to power the system, and the slag from the bottom of the boiler used as main material for producing ceramic tile in the system. The system produces ceramic tile of high quality with coal gangue and domestic garbage, and is environment friendly and economic.

Description

【Technical field】 [0001] The invention relates to a system for processing and utilizing industrial and domestic waste, in particular to a system for producing ceramic bricks by using industrial waste coal gangue and domestic waste. 【Background technique】 [0002] Coal gangue is also called leaf charcoal and stone coal. It is industrial waste when mining coal in various coal mines. Its calorific value is 1000-3000 kcal, and its ash content is 80%. The ash content: SiO 2 60-70%, Al 2 o 3 16-20%, Fe 2 o 3 2 to 4%. In the past, only a small part of these wastes were used as raw materials for making cement, and most of them were discarded and piled up in garbage dumps; urban domestic waste, except for a small amount of non-combustible materials such as metals, was mostly inflammable of organic matter. At present, these domestic wastes are generally dragged to the outskirts of the city for burial, which not only takes up valuable land, but also pollutes air and water sources....
