What are the advantages of low temperature drying machine in drying oily sludge?

Oily sludge comes from petroleum industry. It has high water content, high oil content and high viscosity. It has the characteristics of "oil-water mixture", so it is very difficult to dry. In order to "de oil dehydration", "flame proof and explosion-proof", based on 30 years of drying experience, the low-temperature sludge drying machine was manufactured by ZJN, which greatly reduced the sludge treatment costs of petrochemical enterprises such as oil refineries and oil extraction plants. Now, I will introduce in detail the advantages of this sludge low-temperature dryer in drying oily sludge?

Principle of sludge low temperature drying machine

How does the sludge low-temperature drying machine treat the sludge? I think we don't know much about it. But as we all know, the drying process of materials is the process of water evaporation. Traditionally, we think that water will evaporate only when it is boiling. This perceptual cognition is not comprehensive, because boiling is only a special case of water evaporation; in natural environment, even at very low temperature, water evaporation can still be carried out. For example, in winter we dry our clothes in the yard. The temperature is very low, but the clothes will still dry. However, the evaporation process is so slow that we can't even see it with the naked eye.

Advantages of low temperature sludge drying machine

1. Environmental protection

Compared with high-temperature drying, low temperature can effectively curb the generation of toxic and harmful gases, so that the difficulty of waste gas treatment is reduced and the environmental protection is strong.

2. Energy saving

The temperature requirement of heat source is low, and the heating cost is greatly reduced. We can also use the existing energy such as "boiler tail gas" and "steam" as the heat source, which will bring more benefits.

3. Flameproof and explosion proof

According to the sludge properties and the suitable temperature, the operating parameters of the equipment are calculated to ensure that the temperature is below the flash point of oily sludge, and the explosion-proof and combustion emergency devices are built in, which can be used without worry.

4. Innovation

"Rotary harrow three-cylinder multiple-loop", "low temperature and large air volume" drying technology, deoiling dehydration, staged drying, sludge low-temperature drying machine not only solves the problem that oily sludge is easy to stick, but also improves the drying speed by increasing the air volume. The whole set of equipment operates under negative pressure, which is clean and environmentally friendly.

5. High efficiency

The sludge low-temperature drying machine can dry and shape at one time, and can effectively reduce the volume and weight of the oily sludge with high humidity and high viscosity. The drying effect of the finished product is good, which is suitable for the later resource utilization.
