Embodiment 1

[0026] This embodiment provides a sludge carbonization method with temperature and time control. In the first stage, biomass is carbonized at high temperature to obtain biochar; The composite carbon is obtained by co-carbonizing the sludge peat and livestock manure at low temperature.

[0027] Among them, the temperatures of high temperature carbonization, medium temperature carbonization and low temperature carbonization are 700°C, 500°C and 300°C respectively, and the time of high temperature carbonization, medium temperature carbonization and low temperature carbonization are 60min, 30min and 20min respectively.

[0028] Based on the method of embodiment 1, the ratio of the sludge, biomass and livestock and poultry manure added is different, and the nutrient content of the sludge charcoal obtained is different, and the addition amount of biomass, sludge and livestock and poultry manure is 2- by mass ratio When 3:4-5:1, the available potassium in the obtained sludge charcoal...

Embodiment 2

[0031] Comply with the above technical solutions, such as figure 1 As shown, this embodiment provides a multi-stage temperature-controlled and time-controlled sludge carbonization furnace, which includes an inner cylinder 1, and the inner cylinder 1 drives the screw blade 3 on the transmission shaft 2 through the transmission shaft 2 in the inner cylinder 1 to run. The first carbonized raw material inlet N1 and the second carbonized raw material inlet N2 are arranged in turn on the upper side of the front end of the cylinder 1, and the carbide outlet N3 is arranged on the lower side of the end of the inner cylinder 1. The upper side of the inner cylinder 1 is connected to the second carbonized raw material inlet. A conditioner feed port N4 is provided between the feed port N2 and the carbide outlet N3. The conditioner feed port N4 is to add some low-temperature carbonized substances other than biomass during sludge carbonization, so as to change the sludge carbon. nutrient con...

Embodiment 3

[0039] This example provides a multi-stage temperature-controlled and time-controlled sludge carbonization furnace, which uses municipal sludge as raw material to prepare sludge charcoal, which is used for municipal landscaping. In order to reduce energy consumption costs and increase the nutrient content of sludge charcoal, it is necessary to add Co-carbonization of livestock and poultry manure.

[0040]The biomass enters the inner cylinder 1 from the first carbonization raw material inlet N1, and the 800°C high-temperature flue gas enters the high-temperature heating jacket 4 from the high-temperature heat source inlet N6 to the inner cylinder 1 and is discharged from the high-temperature heat source outlet N7. The biomass is carbonized under the heating of the high-temperature heating jacket 1, and converted into biomass charcoal and combustible gas. With the rotation of the spiral blade 3, the biomass charcoal moves to the tail of the inner cylinder 1.

[0041] The municip...

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, and relates to a sludge carbonization method and equipment, in particular to a temperature-controlled and time-controlled sludge carbonization method and a multi-stage temperature-controlled and time-controlled sludge carbonization furnace. Background technique [0002] Carbonization treatment is a kind of sludge resource utilization method with good cleanliness. At present, the water content of dewatered sludge in my country is still as high as 80%, and it must be dried before further carbonization, and the heat required for drying and carbonization is generally greater than the heat contained in the sludge itself. The use of natural gas, diesel and other energy sources for sludge drying and carbonization often leads to high cost of sludge carbonization treatment, which is also the main reason why many sludge carbonization technologies in my country are difficult to promote. [0003] I...
