What are the difficulties in drying petrochemical sludge dryer?

2021-07-02 10:50

People in petrochemical industry all know that it is very difficult to dry petrochemical sludge, which is determined by its own characteristics. In addition to high water content and large volume, sludge also contains a large number of oil, which belongs to high moisture and high oil hazardous waste. Drying petrochemical sludge, not only high cost, but also has certain security risks, the traditional petrochemical sludge dryer, in the "dehydration drying" is often insufficient, the enterprise often does not know what is the cause.

Drying difficulties of petrochemical sludge dryer:

1. Water oil mixing characteristics

General sludge "dehydration" is the key, but for petrochemical sludge, "deoiling" is also important. Due to the "water oil mixture" characteristics of petrochemical sludge, the moisture content and oil content must meet the drying requirements.

2. It is difficult to remove oil

The permeability and binding force of oil are much stronger than that of water molecules, so it is more difficult to remove oil than water.

3. There are potential safety hazards

In the drying process, there is a hidden danger of explosion caused by combustible hydrocarbon gas.

These drying problems put forward higher requirements for dryer manufacturers. In order to solve the design and manufacturing problems of petrochemical sludge dryer, ZJN environmental protection equipment Technology Co., Ltd. has been studying drying equipment for more than 30 years, using "three-stage and multi loop" drying technology to dehydrate and deoil, and dry in stages to reduce water and oil content at one time; Through the "anti sticking" design, the problem of high humidity and high viscosity sludge sticking to the wall and agglomeration can be solved; the drying temperature should be strictly controlled to ensure that the drying temperature is below the flash point of petrochemical sludge, so as to ensure that the materials in the equipment will not burn or even explode, so as to ensure that the users can use them at ease.
