Abstract

The invention discloses sludge pre-drying carbonization treatment equipment, relates to the technical field of sludge treatment, and solves the problems that existing sludge drying carbonization equipment lacks a dialysis removal structure for moisture in sludge, the moisture stored in the sludge is difficult to discharge and can only depend on heating evaporation, the evaporation drying process of the moisture is relatively long, and the sludge drying efficiency is relatively high. This reduces the efficiency of drying use. The sludge pre-drying carbonization treatment equipment comprises a drying box and a cover plate, the drying box comprises a hearth and T-shaped track strips, the drying box is of a rectangular structure as a whole, the hearth corresponding to the drying box in shape is welded to the bottom of the drying box, and six ventilation grooves are formed in the bottom of the hearth at equal intervals in a penetrating mode; and two T-shaped track strips are symmetrically welded at the bottom of the hearth in a hanging manner. Water in sludge can be dialyzed and discharged by the permeable pipe through the filter cloth on the permeable pipe, so that the content of waterin sludge can be quickly reduced, the drying time of sludge can be shortened, and the drying efficiency can be improved.

Description

technical field

[0001] The invention relates to the technical field of sludge treatment, in particular to a sludge pre-drying carbonization treatment equipment. Background technique

[0002] With the popularization of sewage treatment facilities, the improvement of sewage treatment efficiency and the deepening of sewage treatment, the domestic municipal sludge production has increased rapidly year by year. It is estimated that by 2020, the municipal sludge production will reach 90 million tons. Due to the insufficient sludge treatment and disposal capacity and backward methods in my country, a large amount of sludge has not been treated in a standardized manner, and the stabilization and harmless treatment rate is only 20% to 30%. A large amount of sludge is simply landfilled, wasting a lot of land resources and pose a serious threat to the ecological environment. Sludge has complex components, including pathogenic microorganisms, parasite eggs, toxic and harmful heavy metal...
