Self-propelled solar sludge drying machine

Abstract

The invention relates to a self-propelled solar sludge drying machine, which comprises a workbench, and the upper surface of the workbench is provided with a sludge feeding trough; a spiral sludge pushing unit is arranged in the sludge feeding trough; a feeding bin is arranged above the feeding end of the spiral sludge pushing unit; and hot air flow generating units are arranged on both oppositvesides of the spiral sludge pushing unit. The self-propelled solar sludge drying machine has the beneficial effects of low cost, no secondary pollution, clean energy use, no carbon dioxide production and no heat production, and achieves the goals of sludge reduction and decontamination, energy conservation, emission reduction and environment-friendliness.

Description

technical field [0001] The invention relates to the improvement of sewage and wastewater treatment devices, and more specifically relates to a self-propelled light energy sludge dryer. Background technique [0002] With the rapid development of the economy, the output of sewage has increased year by year, seriously threatening the ecological environment. Therefore, sludge treatment is imminent. In the process of sewage treatment, a large amount of sludge will inevitably be produced, and improper sludge treatment will bring new pollution problems, because the sludge is enriched with a large amount of pollutants from sewage, especially toxic pollutants such as heavy metals. Treatment poses a greater threat to the ecological environment, and the hazards of sludge produced by industrial sewage cannot be ignored. [0003] At present, the daily treatment capacity of urban domestic sewage in my country is about 100 million tons, and the annual sludge production is about 32 millio...

Problems solved by technology

But at the same time, the shortcomings are also very prominent, such as the complex process of incineration treatment facilities, high operating costs, high energy consumption, and the market has not yet been widely promoted

The second category is mainly sludge landfill. First, a certain blending agent is added to the sludge to achieve "stabilization", and then the solid waste is packaged and backfilled into the mine pit, etc., but the disadvantages such as inability to be finally degraded and secondary pollution still exist.

The third category is mainly composting treatment, composting sludge to make it a resource, but it has the disadvantages of long processing time and large area, and the composting has relatively large limitations, limited to domestic sewage sludge, while industrial sewage sludge Mud, etc. are not applicable, and the harmful substances left by composting may cause some damage to the ecological environment

In summary, the treatment technologies at this stage, such as landfill and incineration, cannot fundamentally result in the treatment and disposal of sludge, and there are still "secondary" pollution, low level of sludge treatment, high cost, and high energy consumption.
