A kind of sludge pre-drying carbonization treatment method

Abstract

The invention discloses a sludge pre-drying carbonization treatment method, relates to the technical field of sludge treatment, solves the problem that the existing sludge drying carbonization method lacks a dialysis and removal structure for moisture in the sludge, and the moisture stored in the sludge Difficulty in discharging can only rely on heating and evaporation, resulting in a longer evaporation and drying process of water, which reduces the problem of drying efficiency. The sludge pre-drying carbonization treatment method is completed by the sludge pre-drying carbonization treatment equipment, and then realizes the sludge pre-drying carbonization treatment, which includes the following steps: firstly, the insertion block is inserted through the sliding plate through the electric push rod Block the rear opening of the drying box, and then fill the sludge into the drying box. After the filling is completed, continue to slide down the electric push rod to insert the stopper and make the left and right rows of positioning square rods push down against the drying box. On the bottom inner wall of the box, then start the motor and open the solenoid valve on the air distribution pipe to ignite.

Description

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