The ZJN low-temperature sludge dryer has the characteristics of energy-saving and consumption reduction. The working principle of the low-temperature sludge dryer is to dry materials by reducing the heat source temperature and increasing the air volume under certain conditions. Due to the low requirement of heat source temperature, it can be combined with "boiler exhaust gas utilization" technology to greatly reduce the heating cost. So what are the advantages of using low temperature sludge dryer to dry high humidity and high viscosity sludge? (what are the differences between low temperature sludge drying machine and dehydration equipment in technology) interested friends can learn about it in advance.

Low temperature sludge dryer has several advantages

1. The effect of reducing volume and weight is good

There are several reasons for the difficulty of sludge treatment: first, the source of sludge is wide and the output is large. Whether it is the sludge produced by industrial wastewater or sewage treatment plant, there are a large number of sludge to be treated every day. To dispose the sludge, it is necessary to complete the reduction of sludge. Second, the characteristics of sludge. Sludge has the characteristics of high humidity and high viscosity. Some sludge contains toxic substances such as heavy metals, so it is difficult to treat sludge.

The ZJN low-temperature sludge drying machine can effectively realize the volume reduction and reduction treatment of high humidity and high viscosity sludge. The equipment adopts the three-layer sleeve process, which is upgraded and reformed on the basis of the original single cylinder process. The professional design of "rotary rake crushing" breaking device and the scientific interleaving and distributing lifting system solve the drying problem of high wet sticky sludge, improve the drying speed and quality at the same time. At present, a single equipment can deal with hundreds of tons of sludge every day, and the effect of volume and weight reduction is very obvious. It can fully meet the needs of dehydration and drying of large industrial sludge and municipal sludge.

2. Green environmental protection, realize sludge resource utilization

If the toxic and harmful substances in the sludge are not handled properly, it will cause secondary pollution to the environment. The low temperature drying technology can solve this problem well. In the treatment process, the low temperature sludge drying machine can effectively remove the harmful microorganisms and some toxic substances in the sludge, make the physical and chemical properties of the sludge tend to be stable, eliminate the odor of the sludge, and avoid the pollution of the sludge to the environment.

Moreover, the sludge dried by low-temperature sludge drying machine contains a large number of organic matter and trace elements, which can be used in the field of building materials to make environmental protection brick and ceramsite, plant growth fertilizer or calorific value utilization, so as to realize the recycling of resources.
