An environmentally friendly sludge treatment equipment

Abstract

The invention discloses sludge treatment equipment based on environmental protection, and relates to the technical field of sludge treatment equipment. The invention comprises a bottom plate, an annular steam box is arranged on the surface of the bottom plate; a water storage tank is arranged on the surface of the bottom plate and inside the annular steam box; a heating furnace is fixed on the surface of the bottom plate and inside the annular steam box; a blanking barrel is arranged on the side of the heating furnace; A spiral partition is arranged on the inner wall of the barrel; a sludge storage barrel is arranged on the top of the heating furnace; a discharge pipe is connected to the bottom of the sludge storage barrel; a first steam pipe is connected between the top of the sludge storage barrel and the annular steam box. The invention heats and evaporates the sludge in the sludge storage tank through a heating furnace, and the steam heats the water in the water storage tank, and the evaporated sludge is dried when passing through the spiral partition, and enters the heating crucible for drying. Fuel supplementation, sludge incineration is complete, and the energy recovery and utilization of sludge incineration improves the utilization rate of heat energy, which has the effect of environmental protection.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment equipment, in particular to a sludge treatment equipment based on environmental protection. Background technique [0002] In recent years, the discharge of urban domestic sewage has become the main pollution source of urban water in China. Urban domestic sewage treatment is the top priority of urban water conservation and environmental protection at present and in the future. This requires us to regard the construction of domestic sewage treatment facilities as a city The important content of the infrastructure is to be grasped, and it is an urgent matter. [0003] The key link in sewage treatment is sludge treatment, sludge drying and incineration technology, in order to effectively remove toxic substances in sludge under high temperature combustion state, and realize sludge reduction, harmless and resourceful treatment. , but at present, the processing equipment usually has complex equ...
