Problems solved by technology

[0003] Harmless treatment: 1. The sludge landfill technology must be anti-seepage. Over time, the rupture of the anti-seepage layer may cause groundwater pollution; 2. The sludge composting technology is suitable for sludge with low heavy metal content and high organic matter content , and the scale of treatment is limited, which affects its scope of application; 3. The application range of sludge incineration technology is wide, but improper control of flue gas is likely to cause secondary pollution

Embodiment 1

[0028] An integrated technology for making environmentally friendly bricks from industrial hazardous waste sludge, which is characterized in that it includes the following specific procedures:

[0029] (1) Raw material storage

[0030] The raw material is industrial hazardous waste sludge, and a sludge storage warehouse is set up. The raw material is transported into the factory by car, and the hazardous waste sludge is directly discharged into the sludge storage warehouse. A grab machine is installed on the top of the sludge storage warehouse, and the sludge is discharged into the storage warehouse. , stacked and stored by grab buckets;

[0031] (2) Feeding

[0032] A sludge hopper is installed on the side of the sludge storage, and the raw materials are grabbed by the grab machine, and the materials are homogenized and loaded at the sludge hopper; Conveyor into the drying furnace;

[0033] (3) drying

[0034] Since the raw material is industrial hazardous waste sludge, t...

Abstract

The invention provides an integrated technology used for preparing environment-friendly bricks from industrial hazardous waste sludge. The integrated technology used for preparing environment-friendlybricks from industrial hazardous waste sludge comprises steps of raw material storage, feeding, burning, and brickmaking, and more specifically, dehydrated industrial hazardous waste sludge is subjected to drying in a drying furnace, and is subjected to burning in a rotary kiln, furnace slag obtained through burning is mixed with sand and cement, and an obtained mixture is prepared into baking-free environmental-friendly bricks. According to the integrated technology, industrial hazardous waste sludge is subjected to harmlessness treatment, and brickmaking is carried out. The integrated technology is invented through independent research and development, a complete harmless resource recycling production line is invented based on utilization of industrial hazardous waste sludge; the obtained baking-free environmental-friendly bricks are subjected to environment protection detection, harmless or resource recycling treatment, or sailing or landfill are carried out based on monitoring results, so that complete harmless and resource recycling of industrial hazardous waste sludge is realized, and waste is changed into valuables.

Description

technical field [0001] The invention relates to the technical field of production of environmentally friendly bricks, in particular to an integrated technology for producing environmentally friendly bricks from industrial hazardous waste sludge. Background technique [0002] At present, there are basically two types of disposal methods for industrial hazardous waste sludge: harmless treatment and recycling. Harmless treatment is divided into sludge safe landfill technology, sludge composting technology and sludge incineration technology. Recycling generally refers to comprehensive utilization of hazardous waste sludge after harmless treatment, such as land utilization and production of ceramsite. [0003] Harmless treatment: 1. The sludge landfill technology must be anti-seepage. Over time, the rupture of the anti-seepage layer may cause groundwater pollution; 2. The sludge composting technology is suitable for sludge with low heavy metal content and high organic matter con...
