Status and skills of sludge treatment equipment

  Oil sludge refers to the sludge that occurs in the production process of the oil field because of crude oil excavation, storage, gathering and transportation, processing, and crude oil production fluid treatment. It is known for containing crude oil or certain components in crude oil. Mainly divided into: ground sludge, clear tank sludge, flotation scum, etc.

Oil sludge generally has an oil content of 10-50% and a water content of 40-90%. In my country’s petrochemical industry, an average of 800,000 tons of tank bottom sludge and pool bottom sludge occur every year. Shengli Oilfield produces 100,000 tons of oily sludge every year. Above, Dagang Oilfield produces about 150,000 tons of oily sludge annually, and Henan Oilfield produces 5X104m3 of oily sludge annually. Oily sludge contains a large amount of benzene series, powders, and other substances. If the sludge treatment equipment is directly discharged, it will not only occupy a large amount of cultivated land, but also pollute the surrounding soil, water and air. The sludge also contains a large amount of Copper, zinc, chromium, mercury and other metals, salts, and hard-to-degrade hazardous substances such as PCBs, dioxins, and radionuclides. Now, sludge has been classified as hazardous waste by our country.

  The status quo and skills of sludge treatment equipment

   With the continuous excavation of petroleum resources, resources will become less and less, and the difficulty of excavation will become greater and greater, so various additives will continue to increase in the process of oil extraction. As a result, the components of the sludge are varied, and the sludge treatment equipment and processes will be changed accordingly. There are many varieties of sludge treatment equipment, processes and methods, all with their own characteristics.

   The methods for sludge treatment equipment at home and abroad generally include incineration, biological treatment, hot scrubbing, solvent extraction, chemical demulsification, solid-liquid separation, etc. Although there are many methods for sludge treatment equipment, they have not been promoted due to disadvantages such as poor pertinence and high processing costs. It is difficult to achieve severe environmental protection requirements with a single process and skills. Therefore, the combined use of multiple sludge treatment equipment processes and methods is one of the development directions of the harmless treatment of sludge in the future.

What are the guidelines for the use of decanter centrifuges?

 

The first thing to pay attention to use the decanter centrifuge is safety, the uncontrolled centrifugal force may cause great damage. Therefore, pay attention to whether the centrifuge tube is balanced, whether the speed exceeds the setting, whether the rotor is corroded, etc. Decanter centrifuges seem simple to use and have no technical content, but correct use and protection are still necessary. Once a failure occurs, it will delay the test, which is not worth the gain.

        1. When the centrifuge is in the pre-cooling condition, the centrifuge cover must be closed. After the centrifugation, the rotor should be placed upside down on the test bench, and the remaining water in the cavity should be wiped off. At this moment, the decanter centrifuge cover is in the open condition.

        2. When the rotor is pre-cooled, the rotor cover can be placed on the platform of the centrifuge or placed on the test bench. Never tighten the rotor and float on the rotor. Once it is started by mistake, the rotor cover will fly. Out and cause an accident!

  3. After the rotor cover is tightened, there must be no gap between the rotor and the rotor cover with your fingers. If there is a gap, unscrew and re-tighten the centrifuge until it is confirmed that there is no gap.

  4. During the centrifugation process, the operator must not leave the centrifuge room. Once an abnormal situation occurs, the operator cannot turn off the power (POWER) and press STOP. Fill in the decanter centrifuge usage record before pre-cooling.

   5. Do not use fake or inferior centrifuge tubes, and do not use aged, deformed or cracked centrifuge tubes.

   6. During holidays and evenings, the decanter centrifuge must undergo routine safety inspections before leaving.

  7. If there is a machine failure during the use of the instrument, and the parts are damaged, please contact the manufacturer in time.

Problems to be paid attention to when using decanter centrifuge

 

Decanter centrifuge has good separation and washing effect under the action of centrifugal force, strong adaptability to materials, suitable for separating solid-phase particles ≧0.01mm suspension. Decanter centrifuges are widely used in biochemistry, fine chemicals, pharmaceuticals and other fields. It is a filter centrifuge with automatic scraper discharge and intermittent operation.

  1. Precautions for the use of decanter centrifuge

    (1) Fabrics with different water absorption strengths should be dehydrated separately.

    (2) The newly installed dehydrator or the newly connected wire must ensure that the motor rotates in the correct direction.

    (3) When the fabric is placed severely unevenly and causes intense vibration, the power switch should be turned off immediately, and the fabric should be placed evenly from the beginning before dehydration.

    (4) Do not overload the amount of fabric placed. Especially pay attention when taking off other items other than clothing.

    (5) When the machine is working, do not reach into the inner cage area of ​​the dehydrator

2. How to use the decanter centrifuge?

    (1) Before use, first check whether the mechanical parts are in good condition.

    (2) Place the level meter washing evenly in the inner rotating cage.

    (3) Start the electric motor to gradually accelerate the speed of the inner cage. According to the type of fabric, it can be dried in 5-10 minutes.

    (4) Press the "Stop" button to power off the motor. After the dehydrator has been naturally decelerated for a period of time, manipulate the brake lever to perform intermittent braking operations to complete the stop of the inner cage.

    (5) After the machine stops, the fabric can be taken out.

How to correctly operate the decanter centrifuge

 

Decanter centrifuges are used more and more frequently in the production field. Of course, as staff, we must be proficient in relevant operating skills. Only in this way can we use them reasonably and make them in ideal working conditions. So for the decanter centrifuge equipment, what is the correct operation method in detail? Next, let's take a look at the detailed content.

   Obviously, if the correct operation method is used, it can not only ensure the normal progress of our work, but also effectively extend the service life of the decanter centrifuge, and also effectively reduce the failure rate of the equipment. So, how do you do it after all? First of all, we must ensure that the equipment is placed on a flat surface and fixed.

   After confirming that there is no abnormal problem, connect the appropriate power supply voltage to the equipment, and install it back as required, and then place the material in the decanter centrifuge cavity. After that, close the door of the equipment, and set the temperature, speed, time and rotation speed according to the actual situation. Then open the equipment and enter the state of normal production. In this process, you should pay attention to the operation status of the decanter centrifuge, and deal with it in time if any problems are found.

   When the separation work is completed, we should shut down the equipment, and only after the decanter centrifuge is completely stopped, can we open the door and take out the separated material. After that, use a clean cloth to scrub the inside of the equipment and back, and keep it clean. After that, the temperature of the internal cavity of the device is consistent with the room temperature, and then the door is closed.

The correct use method of decanter centrifuge is as above. As long as we use the equipment according to the correct use method, and conduct inspection and maintenance at regular intervals, then the service life of the equipment can be extended. I hope this article can help you understand the decanter centrifuge equipment more comprehensively.
