Embodiment Construction

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on The embodiments of the present invention and all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] as attached Figure 1-8 As shown, an energy-saving sludge and domestic waste mixed treatment equipment includes a garbage storage bin 1, which is used for temporarily storing garbage and seeping and dehydrating the moisture in the garbage. A driving grab is arranged above the garbage storage bin 1 2. The driving grab 2 is used to grab the garbage in the garbage storage bin 1 into the hopper 3, and there is a hopper 3 on the right side of ...

Abstract

Energy-saving sludge and household garbage mixing treatment equipment comprises a garbage storage bin, a traveling crane grab bucket is arranged above the garbage storage bin, a hopper is arranged on the right side of the garbage storage bin, a spiral feeder is arranged below the hopper, a sludge dewatering and drying mechanism is arranged on the right side of the hopper, the sludge dewatering and drying mechanism comprises a dewatering mechanism and a drying mechanism, a grate furnace is arranged on the right side of the screw feeder, and an ash treatment box is arranged on the right side of the grate furnace. According to the energy-saving sludge and household garbage mixed treatment equipment, a second shell with a double-layer cavity is arranged, high-temperature flue gas is introduced into the outer-layer cavity of the second shell to conduct heat preservation and heating on the outer shell, and meanwhile, through heat exchange between the high-temperature flue gas and a spring tube filled with air, the heated air dries the sludge in the cavity on the inner side of the second shell, so that the double-layer drying effect is achieved, the sludge drying effect is better; and through reutilization of the high-temperature flue gas, the energy consumption in the sludge drying process is reduced.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, and more specifically relates to an energy-saving mixed treatment equipment for sludge and domestic garbage. Background technique [0002] With the continuous development of social urbanization and modernization in our country, many by-products will be produced in the process of industrial production, and sludge is one of the main by-products. The best means for sludge treatment is dehydration and drying followed by incineration. , but ordinary sludge incineration methods consume a lot of energy to incinerate sludge. The latest method is to solve the problem of high energy consumption of single sludge incineration through the mixed combustion of sludge and domestic waste. Mixing sludge and domestic waste In the past, it was necessary to dehydrate and dry the sludge, and the drying of the sludge required the drying of the sludge, which consumed a lot of energy and the drying efficiency w...
