Abstract

The invention discloses a low-vacuum sludge drying system, and relates to the technical field of sludge drying. The system comprises a wet sludge bin, an arch breaking device, a conveying device, a feeding flexible connecting section, a low-vacuum sludge drying device, a discharging flexible connecting section, a buffer bin, a vacuum conveying device, a dry sludge bin, an efficient bag type dust removal device, a Roots blower, a cyclone dust removal device, an efficient bag type dust remover, a storage bin, a condenser, a vacuum system, an incineration device, a chimney and a deodorization device, wherein the arch breaking device is mounted on the wet sludge bin. The low-vacuum sludge drying system provided by the invention is of a fully-sealed structure, the sludge drying device is subjected to space air exhaust through the vacuum system, so that a certain negative pressure state is formed in the sludge drying device, and sludge drying is carried out in the negative pressure state environment; not only is the boiling point temperature reduced, but also the water evaporation speed is increased; and the overall operation energy consumption of the equipment is directly reduced, so that the energy-saving effect is achieved.

Description

technical field [0001] The invention relates to the technical field of sludge drying, in particular to a low vacuum sludge drying system. Background technique [0002] In recent years, the Chinese government has attached great importance to the treatment of sludge, and has increased investment in the advanced treatment of sludge in sewage plants, and the scale has also continued to expand. With the continuous determination and implementation of environmental protection by the country, the introduction of national environmental standards, and the clear realization of goals, my country has made rapid breakthroughs and developments in sewage treatment and sludge treatment in the process of urbanization. [0003] However, through the improvement of sewage treatment in the past, the amount of sludge produced has also increased year by year, and the problem of sludge treatment and disposal has become increasingly prominent. In response to these series of problems, there is an urg...
