Electromagnetic energy rapid sterilization sludge dehumidifying and drying system

Abstract

The invention relates to the technical field of sludge treatment, in particular to an electromagnetic energy rapid sterilization sludge dehumidifying and drying system, which comprises a feeding part, a drying line and a discharging part, wherein the feeding part is connected with a feed end of the drying line; the discharging part is connected with a discharge end of the drying line; the drying line is provided with a box body; the box body constructs a sealed drying chamber; a sludge drawing mechanism and a dust collecting device are arranged in the box body; the dust collecting device is located in a dust falling direction of the sludge drawing mechanism; the box body provides electromagnetic energy and hot air for sterilizing and drying sludge on the sludge drawing mechanism; the sludge drawing mechanism has the effects of vibrating and turning over the sludge thereon. The electromagnetic energy rapid sterilization sludge dehumidifying and drying system provided by the invention has the advantages of integrating sterilizing and drying, comprehensively improving a sludge drying effect, being energy-saving and environment-friendly, avoiding secondary pollution, effectively treating biological active cells in the sludge, being beneficial for sludge recycling, achieving higher safety, and having a wide market application prospect.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a sludge drying system. Background technique [0002] Sludge drying is the follow-up part of sewage treatment. With the acceleration of urbanization in China, the number of urban sewage treatment plants is still increasing, and the sludge output is also showing a trend of continuous and rapid growth. Social concern has prompted the country to pay attention to sludge treatment and disposal, and the country's attention has prompted the formation of a sludge treatment and disposal market. At present, sludge disposal in large cities has become difficult and expensive, long-distance sludge haulage, fuel and transportation costs have increased, sludge landfills consume a lot of land resources, and costs have increased, wet sludge direct incineration is expensive, and because Due to problems such as smog, citizens opposed the construction of incinerators in the city. The exis...

AI Technical Summary

Problems solved by technology

[0003] 1. When thermal dehydration is used, pollutants such as dust, flue gas, and hot oil will be produced during the sludge drying process, which will adversely affect the surrounding environment

[0004] 2. When mechanical dehydration is used, since the mechanical dehydration removes only the free interstitial water in the sludge, the sludge moisture still exists about 75%-85% after dehydration, but the moisture content of 75%-85% does not The sludge cannot be disposed of directly, and the toxic and harmful substances contained in it have not been processed. Therefore, there is a problem of low sludge drying efficiency

[0005] 3. Complex structure and high cost
