Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0038] The present invention is a kind of device that utilizes furnace smoke to treat municipal sludge, such as figure 1 As shown, it includes an integrated sludge treatment machine 1 and a furnace flue pipe, wherein the integrated sludge treatment machine 1 is as figure 1 As shown in the dotted line box, it includes a rotary sludge drying drum 2 , a pulverizing conveying fan 3 and a steam condenser 4 . like figure 2 As shown, several radial partitions 6 arranged axially inside the rotary sludge drying drum 2 are divided into multiple cavities, and heat storage balls 8 are placed in the cavities. The partitions are arranged radially, and the radial length smaller than the radius of the rotary sludge drying drum 2, so that the cavity communicates with the center of the rotary sludge drying ...

Abstract

The invention provides a system and method for treatment of municipal sludge with furnace smoke. The system is characterized by simple structure, small energy consumption and low operation cost, can achieve continuous, safe and efficient utilization of smoke for drying treatment and transportation of sludge, and at the same time can recycle water in sludge. The system comprises a furnace smoke pipeline and a sludge integrated disposer. The sludge integrated disposer includes a rotary sludge drying roller, a crushing conveying fan and a steam condenser. The furnace smoke pipeline comprises a furnace smoke input pipeline and a furnace smoke output pipeline. A smoke inlet of the rotary sludge drying roller is connected to the furnace smoke input pipeline, a smoke outlet is connected to the crushing conveying fan, and the rotary sludge drying roller is equipped with a sludge inlet connected to a sludge feeder; a plurality of heat storage balls are placed in the rotary sludge drying roller;the steam condenser and the rotary sludge drying roller are in parallel connection, or in series connection between the rotary sludge drying roller and the crushing conveying fan; and an outlet of the crushing conveying fan is connected to the furnace smoke output pipeline.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a system and method for treating urban sludge with furnace smoke. Background technique [0002] Municipal sludge is the sludge generated during the operation and maintenance of urban life and urban municipal facilities related to urban life activities. According to its source, urban sludge is mainly divided into urban sewage plant sludge, urban water supply sludge, urban water dredging sludge, urban drainage channel sludge, urban construction site sludge, etc. With the acceleration of my country's urbanization process, the amount of urban sludge has increased significantly, and social governance problems such as sludge siege have emerged. Traditional municipal sludge disposal methods mainly include sanitary landfill, land use, incineration, and throwing into the sea. However, traditional municipal sludge disposal methods have problems such as secondary pollution, diffic...
