Centrifugal dewatering and drying integrated machine

Abstract

The invention discloses a centrifugal dewatering and drying integrated machine, and relates to the technical field of dehydration and drying devices. The centrifugal dewatering and drying integrated machine comprises a tank body, a discharging outlet is formed in the bottom of the tank body, a centrifugal dewatering machine is arranged on the lateral surface of the tank body, the top of the tank body is provided with a steam collecting pipe, and a steam outlet end of the steam collecting pipe is fixedly connected with an air inlet end of a negative pressure blower. An air outlet end of the negative pressure blower is fixedly connected with an air inlet end of a round pipe, an air outlet end of the round pipe is fixedly connected with an air inlet end of a waste heat recovery device, the other air inlet end of the waste heat recovery device is provided with a control valve, and an air outlet end of the waste heat recovery device is fixedly connected with an air inlet end of a heating device through a first connecting pipe. By arranging the negative air blower, the waste heat recovery device, a motor, a disc and a sludge scraping plate, the problem that an existing sludge treatment device is poor in sludge dewatering and drying effect is solved.

Description

technical field [0001] The invention relates to the technical field of dehydration and drying devices, in particular to an integrated centrifugal dehydration and drying machine. Background technique [0002] At present, the problem of excess sludge treatment in urban sewage plants is very serious, and there is a great demand for water pollution prevention and treatment and sludge reduction. At present, the development level in the field of excess sludge reduction and excess sludge reuse is relatively low. Compared with developed countries, there is still a big gap. [0003] At this stage, the remaining sludge is mainly incinerated and sanitary landfill, accounting for about 80% of the treatment capacity. There is no more effective sludge drying and reduction equipment from the source, resulting in high cost and low efficiency in the sludge treatment process. It cannot meet the current environmental protection development requirements, so it is necessary to provide a centrif...

[0002] At present, the problem of excess sludge treatment in urban sewage plants is very serious, and there is a great demand for water pollution prevention and treatment and sludge reduction. At present, the development level in the field of excess sludge reduction and excess sludge reuse is relatively low. Compared with developed countries, there is still a big gap

[0003] The remaining sludge is mainly incinerated and sanitary landfill at this stage, accounting for about 80% of the treatment capacity. There is no effective sludge drying and reduction equipment from the source, resulting in high cost and low efficiency in the sludge treatment process. It cannot meet the current environmental protection development requirements, so it is necessary to provide a centrifugal dehydration and drying all-in-one machine with better dehydration and drying effect
