Description
Technical Field
The utility model relates to the technical field of sludge treatment, in particular to a sludge press filtration, dehydration, airing and drying and incineration power generation treatment system.
Background
Municipal sludge is a necessary product of sewage treatment plants and sewage treatment in general. After the sludge which is not properly treated enters the environment, secondary pollution is directly brought to underground soil, water and atmosphere, so that the effective treatment capacity of a sewage treatment system is reduced, and serious threat is formed to the ecological environment and human activities. The treatment problem is increasingly prominent due to the large amount of sludge, and the sludge becomes a difficult problem facing each sewage treatment industry in China, and compared with the rapid development of sewage treatment, the sludge treatment technology in China is just started. The treatment and disposal modes of the sludge in China mainly comprise modes of land utilization, incineration, building material utilization, landfill and the like, and the sludge drying mode is generally drying through a drying shed, a drying box and the like.
Due to the characteristics of sludge, the following problems mainly exist in the sludge treatment process:
on one hand, the sludge containing about 85% of water in a factory is difficult to break wall and evaporate in the drying process of the microbial cell water in the sludge. On the other hand, the flocculating agent and other agents are added in the dehydration process of the sewage treatment plant of the sewage entering the factory, so that the characteristics of the sewage become sticky semi-liquid, and the current situation that the operation of the drying process is unstable and the efficiency is low is caused.
The sludge emits bad smell in the heat exchange drying treatment process to different extent, influences the production workshop and factory environment, leaves environmental protection risk for enterprises, and causes industrial interruption of recycling and reutilization of the dried sludge due to the bad smell carried by the dried sludge, such as: and the red brick factory and the low-heat-value inferior coal are put into a furnace for combustion and the like, so that the resource waste is caused.
The fuel heating method is adopted to evaporate the water in the sludge, and the method has low efficiency, high cost and difficult maintenance.
As disclosed in patent document CN108947202a, a system and a method for drying sludge by composite heat are disclosed, which adopt the greenhouse effect of a transparent drying greenhouse, and utilize the waste heat of steam from a power plant as an auxiliary heat source for drying, but the method improves the dehydration efficiency of sludge drying to a certain extent, but has the problems of limited drying amount, low drying efficiency and volatilizing and overflowing of the fermented off-odor, and the process design does not consider local extremely cold climate, so that the whole heating period is stopped.
Patent document CN217535795U discloses a device for drying sludge by adopting a drying box, which can remove moisture in the sludge inside the sludge box, so that the sludge can be rapidly dried, but the device has higher energy consumption in the sludge drying process due to the use of electricity for heating, and has poor cutting operation effect after drying the sludge by the scheme of the patent due to high water content and high viscosity of the sludge entering a factory of a sewage treatment plant, so that drying efficiency is low.
With the great increase of the sludge treatment capacity, the sludge drying by adopting a single drying greenhouse or drying box can not meet the requirements of sludge drying treatment.
In order to realize the reduction, stabilization, harmlessness and recycling of municipal sludge treatment, a new sludge drying treatment scheme is necessary.
