Example Embodiment

[0033] Example 1

[0034] The remaining sludge of the municipal sewage treatment plant is modified with a modifier. The modification temperature is controlled at 45°C to 60°C, and the modification time is controlled at 25 days. The modified residual sludge of the urban sewage treatment plant is transported to the feeding bin 2 through an external belt conveyor, and the residual sludge of the urban sewage treatment plant enters the positive thread in the reaction bin 2 after being measured. The delivery pipe 22. At this time, the furnace 24 uses gas or biomass fuel to heat the forward threaded conveying pipe 22, and the temperature is controlled at 330°C. At this time, the driving motor 3 drives the forward screw conveying pipe 22 to rotate forward and the reverse screw conveying pipe 23 to rotate in reverse. The remaining sludge of the urban sewage treatment plant is extracted inside the forward threaded conveying pipe 22, and the extracted oil and gas are respectively collecte...

[0039] Example 3

[0040] The filter mud produced by sugar refining is modified by adding a modifier. The modification temperature is controlled at 40°C to 60°C, and the modification time is controlled at 30 days. The modified filter mud is transported to the upper silo 1 through an external belt conveyor, and the filter mud enters the forward threaded conveying pipe 22 in the reaction chamber 2 after being metered. At this time, the furnace 24 uses gas or biomass fuel to heat the forward threaded conveying pipe 22, and the temperature is controlled at 350°C. At this time, the driving motor 3 drives the forward threaded conveying pipe 22 to rotate forward. And driving the reverse threaded conveying pipe 23 to reverse rotation. The filter mud is extracted inside the forward threaded conveying pipe 22, and the extracted oil and gas are respectively collected through the first collection pipe 41 and the second collection pipe 44, and the collected oil and gas pass through the first...

Abstract

The invention discloses and provides a method for modifying organic sludge to prepare fuel oil, which is capable of solving the problem of the organic sludge on environment pollution and simultaneously solving the problem that the organic sludge is incomplete in combustion after dewatering. The method comprises the following steps of a, modifying the organic sludge; b, cooling the modified organic sludge obtained in step a after extracting by a low-temperature extraction device, and obtaining light oil and heavy oil, wherein inorganic substances are the main compositions of residual substances of the organic sludge after oil extraction. The invention also discloses and provides a reasonable-in-design, simple and practical device for preparing the fuel oil by using the organic sludge. The device for preparing the fuel oil by using the organic sludge comprises a feed bin, a reaction bin, an oil recycling mechanism and a driving motor, wherein the feed bin is arranged on the reaction bin; the oil recycling mechanism is arranged at two ends of the reaction bin; the reaction bin is connected with the driving motor. The method and the device, disclosed and provided by the invention, are suitable for the field of organic sludge treatment.

Description

technical field [0001] The invention relates to a method and a device for preparing fuel oil by modifying organic sludge. Background technique [0002] Among organic sludge such as excess sludge produced by urban sewage treatment plants, black and odorous river bottom sludge, industrial sewage after biochemical treatment, and industrial organic waste residue, only a small amount of organic sludge can be directly burned as fuel. Most of the substances do not have the conditions for direct combustion. If they are stored anywhere or burned indiscriminately, they will easily cause certain pollution to the environment. At present, the disposal methods of organic sludge mostly use dehydration equipment, such as belt filter press with complex structure, plate and frame machine, etc. The main method is to reduce the internal moisture content of the sludge, and then mix it with other substances such as coal, diesel oil, etc. Then it is directly incinerated. This combustion method ca...
