Embodiment 1

[0052] When the biochar is produced for the first time (the device starts to work), the remaining sludge or the sludge-based biochar fully mixed with the metal ion solution (such as magnesium chloride solution) is first placed in the water bath drying box 6, and the heating of the water bath area 10 The device 14 will start automatically, heat the water temperature to 80° C. through electric energy and maintain this temperature until the humidity sensor 8 in the drying area reaches the preset value. Afterwards, the whole sludge or biochar storage container 7 will be sent into the carbonization zone 17 in the carbonization furnace along the conveyor chain 5 by the push block 13, and both sides of all four partial box devices can be opened and closed automatically. After entering the carbonization zone 17, the nitrogen inlet pipe 16 will be opened and continue to feed nitrogen until the carbonization zone is in a vacuum state, then the heating device will be turned on, and the te...

Embodiment 2

[0054] Continuous production after the first production (device works continuously without stopping). According to embodiment 1 as can be known, when continuous production, because heat accumulating cooling zone 21 stores excess heat when carbonization, therefore can heat the temperature of water bath district 10 waters by the boiling water of 20 in the cooling circulation pipe of accumulating cooling zone 21, When the water temperature exceeds 85°C, the valve of the water inlet pipe 12 in the water bath area 10 will be closed, but it will not be opened again until the temperature drops below 80°C. During this process, the heating device 14 can not be activated (no additional energy consumption) To dry sludge or sludge-based biochar thoroughly mixed with metal ion solution (such as magnesium chloride solution). Reached the purpose of energy saving. If the heat energy collected is not enough to dry the sludge or the sludge-based biochar fully mixed with the metal ion solution ...

Embodiment 3

[0056] Modified sludge-based biochar. Take magnesium ion modification as an example (magnesium chloride solution): fully mix magnesium chloride solution with sludge-based biochar (the volume ratio of magnesium chloride solution to sludge-based biochar is about 4:1). Then place it in a water bath oven (6) and dry it. Production process is identical with process in embodiment 1 or embodiment 2 afterwards.

Abstract

The invention discloses an energy-saving automatic sludge-based biochar production and modification device, and belongs to the technical field. The device comprises four parts, namely, a water bath drying box, a carbonization furnace for sludge carbonization, a crushing device and a biochar storage box; each of the water bath drying box, the carbonization furnace, the crushing device and the biochar storage box is an all closed box body with the side walls at the two ends capable of being opened; and thedevice further comprises a sludge orcharcoal container. The whole device is provided with aconveying chain for conveying the sludge or biochar container among the four parts, and a push block is arranged on the conveying chain. With the device of the invention adopted, the problems of lowresource utilization rate of excess sludge, high cost of biochar for environmental governance and the like are solved, and the defects of an existing sludge-based biochar device are overcome.

Description

technical field [0001] The invention relates to a sludge-based biochar production and modification device, belonging to the technical field of energy saving and environmental protection. Background technique [0002] With the increasing amount of residual sludge in sewage treatment plants, its treatment or resource utilization has become a problem. At present, the common method is landfill or incineration, but landfill will cause a certain amount of secondary pollution, and incineration will waste a lot of heat energy (the water content of the remaining sludge itself is generally about 80%) and no beneficial products can be obtained. Therefore, how to better utilize it as a resource has always been a research hotspot, and modifying it to prepare biochar is a good resource utilization method. [0003] Biochar is the carbon-rich solid by-product remaining after the pyrolysis of biomass in anaerobic or low-oxygen conditions. In recent years, due to the significant environment...
