The belt sludge drying incinerator, which can “eat†30 tons of sludge every day, was successfully developed in the Taizhou Luqiao, Zhejiang Province, and entered the trial phase. It is understood that this machine was developed by Zhang Jinhua, engineer of Luqiao District Sewage Treatment Company.
After entering the wastewater treatment site at Luqiao Sewage Treatment Co., the reporter saw two workers throw a spatula-like thing into a gray “big guy†and, as a result, the “big guy†emerged from the flames. This strange "big guy" is a belt-type sludge drying incinerator that exclusively "eats" the sludge.
According to Zhang Jinhua, after the dry incinerator with a length of 26 meters, a height of 4.8 meters and an area of ​​300 square meters began to operate, the sludge was sent to the upper filter belt along with the spiral conveyor belt, and then passed through the middle and lower belt respectively. At the time, the water content of the sludge was reduced from 80% to below 25%, and then it was made into mudballs by the machine and placed in the furnace to be burned. The heat generated by the combustion was returned to the dryer cabin. Dry the remaining damp sludge. In order to prevent the smoke from polluting the environment, the discharged exhaust gas is treated by a cyclone and a biological deodorizing spray washing tank, and then discharged through a chimney to achieve a harmless treatment of the sludge.
"Our company can recover 30 tons of sludge per day on average. The sludge that is produced every day is burned through the drying incinerator." Zhang Jinhua told reporters that after burning every 100 tons of sludge left only 6 tons of dust-like residues . At the same time, since the temperature in the incinerator is as high as 800 degrees Celsius, all pathogens and pathogens are completely killed, and toxic and harmful organic residues are also oxidized and decomposed.
It is reported that this time, Zhang Jinhua's belt drying incinerator integrated with drying and incineration is at the leading level in the same industry in China. It will not only cause secondary environmental pollution in landfills, but also save sludge in one year. 15 acres of land for landfill.
