Embodiment Construction

[0032] The structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0033] see figure 1 As shown, a sludge incineration power generation device includes a hopper 1, a conveyor 2, a dryer 3, a boiler 4, a gas separator 7, a first fan 6, a second fan 9, and a third fan 12. The three blowers 12 are also called the inlet fan. The blanking hopper 1 has an inlet at the top and an outlet at the bottom. The inlet of the blanking hopper 1 can be covered by a cover. The starting end of the conveyor 2 is set below the outlet of the blanking hopper 1. The dryer 3 There is an inlet, an outlet and an air inlet capable of receiving sludge from the end of the conveyor 2, and the boiler 4 has an inlet, an outlet that can communicate with the inlet of the dryer 3 through the first blower 6 The gas port, the material gas separator 7 has a feed port that can be communicated with the discharge port of the dryer 3, a discharge port th...

Abstract

The invention discloses a sludge incineration generating device. In the device, sludge is conveyed to a drying machine by a conveyor from a blanking hopper, and flue gas exhausted from a gas outlet of a boiler by a first fan is blown into the drying machine to dry the sludge; the mixture of the dried sludge and the flue gas enters an object-gas separator, so that the dried sludge is separated from the flue gas; the flue gas is exhausted, and the dried sludge is blown into the boiler by a second fan through oxygen-containing gas to be incinerated, so that power generation or heat supply is realized and heat energy is utilized fully; after the sludge enters the blanking hopper, an inlet of the blanking hopper is covered by a cover, so the smell of the sludge is prevented from overflowing outwards, and the environment is prevented from being polluted; and gas generated by the sludge contains combustible gas such as methane, ethane and the like, and is conveyed into the boiler by a third fan to be combusted, so that the heat energy is utilized further to realize waste control by wastes, save energy and protect the environment.

Description

[0001] technical field [0002] The invention relates to a sludge incineration power generation device. [0003] Background technique [0004] The sludge treatment methods in my country mainly include agricultural use, landfill and incineration. Although sludge agricultural use and landfill are simple, easy, and low in cost, the composition of sludge is complex and contains a large amount of harmful substances, especially in urban sludge, printing and dyeing sludge, and industrial water treatment sludge. Heavy metal substances, pathogens and persistent organic pollutants, these will bring pollution to the environment again. Sludge incineration can completely remove moisture and organic impurities in sludge, kill pathogens, and turn sludge into a little ashes at the same time. However, due to the large investment and high operating costs of sludge incineration equipment, it is relatively seldom used in China at present. , and less of it is used for power generation. Most ...
