Final disposal and utilization of sludgeⅡ

After sludge is treated and disposed by a series of methods, there are generally the following final disposal methods for the dried sludge:

Energy utilization

For sludge, engineering technology can be adopted to extract and synthesize the organic matter and heavy metal elements rich in sludge, so as to realize energy recovery. At present, sludge can be treated in an anaerobic environment, so that the microorganisms contained in the sludge can be fully fermented and degraded, and finally produce methane gas. After the methane is collected, it can be used as clean fuel, and the residual solid can be used as organic fertilizer. In the protection of the environment at the same time, the realization of high resource requirements. In addition, there are a series of technologies such as low-temperature sludge oil production technology and sludge fuel utilization technology to realize energy utilization.

Sludge for building materials

Another way to solve the sludge disposal is using sludge production of building materials, asphalt, through engineering technology can achieve the sludge system sludge ceramics grain biochemical fiberboard, sludge, sludge system of ecological cement and other building materials, the sludge of waste disposal requirements, protection of the environment at the same time to achieve the sludge.

With the development of drilling technology, drilling depth is deeper and deeper, and mud requirements are more and more strict.

With the development of drilling technology, drilling depth is deeper and deeper, and mud requirements are more and more strict. Some complex geological conditions under the ordinary mud shaker can no longer meet the requirements of use. Moreover, the performance of the ordinary drilling vibrating screen is not very stable, and the effect of drilling vibrating screen treatment can not be adapted according to the drilling geology, often there will be some run-slurry or “horseshoe effect”. The appearance of the translational elliptical vibrating screen has solved these problems.

The translational elliptical vibrating screen USES 2 vibration motors of different sizes and keeps them on a datum level. Due to the different steering and excitation force of the two motors, the motion trajectory is elliptical. And the movement track of the whole sieve box of the translational elliptical vibrating screen is the same. The ellipse of the translational ellipse vibrating screen is different from the ordinary ellipse, the ellipse track and the screen have a certain Angle, so the “horseshoe effect” is avoided.

Advantages of translational elliptical vibrating screen:

  1. Treatment capacity is increased by 25%-30% compared with linear vibrating screen;
  2. Can adapt to a variety of geological conditions drilling mud recovery and purification;
  3. The excitation force can be adjusted;
  4. Linear vibrating screen has the advantages of translational elliptical vibrating screen have.

The liquid-gas separator is mainly used to deal with large bubbles in drilling fluid.

The liquid-gas separator is mainly used to deal with large bubbles in drilling fluid. When gas invasion occurs, throttle exhaust operation should be carried out. When overflow occurs, kill the well; Drilling fluid enters the liquid-gas separator from the throttling manifold for degassing.

The drilling fluid separated from the above two conditions has small bubbles, which enter the vibrating screen for degassing, flow to the sunk sand bin, and then enter the vacuum degasser device for conventional degassing.

In the ultra-high pressure gas well drilling, because into the cylinder gas volume, liquid volume is very different. This requires that the treatment capacity of the separator should have a relatively wide range of adaptability, and its treatment capacity of gas and liquid should be able to meet the needs of well killing construction. In the design of the scheme, the following considerations should be taken into account:

  1. The task of the liquid-gas separator is to deal with the continuous gas phase and large bubbles;
  2. Provide appropriate residence time for small bubbles to gather in a certain depth below the liquid level;
  3. Solid debris cannot be deposited in the separator;
  4. Apart from the gas column reaching the wellhead, the separator can work normally.

The screw conveyor produced by xi ‘an KOSUN is used in the drilling waste disposal project.

The screw conveyor produced by xi ‘an KOSUN is used in the drilling waste disposal project, providing an effective and low-cost drillings transportation system for offshore drilling and land drilling devices. The screw conveyor adopts the combined structure of more than 12 feet in each section, which can be flexibly assembled and used in different drilling sites, with simple operation, stable structure, strong adaptability in working space and high safety performance. Thus, the working efficiency of the equipment is greatly improved and the cost and resources are saved. The screw blade of screw conveyor is made of wear-resistant material to ensure its service life.

When the screw shaft rotates, the material can only move forward along the bottom of the screw conveyor under the push of the blade due to the gravity of the material and the friction generated by the friction between the material and the tank wall, which is just like the translation movement of the unrotatable nut along the rotating screw. The movement of the material in the intermediate bearing depends on the thrust of the material moving forward behind it. Therefore, the material transport in the conveyor, is a complete slip motion. In order to make the spiral shaft in a more favorable tension state, generally will drive the device and discharge port on the same end of the conveyor, and the feed port as far as possible on the other end of the tail near. The rotating spiral blade moves the material and carries on the transportation, causes the material not to revolve together with the spiral conveyor blade the force is the material own weight and the screw conveyor casing to the material the friction resistance. According to the different materials, there are solid surface, belt surface and blade surface. The spiral shaft of the screw conveyor has a thrust bearing at the end of the direction of material movement. Intermediate hanging bearings should be added when the captain is longer.
