Vertical cuttings dryer is a continuous operation of the dryer.

Vertical cuttings dryer is a continuous operation of the dryer. It has the characteristics of large processing capacity, low energy consumption, stable performance and good separation effect. It can continuously feed, dehydrate and unload the feed liquid at full speed. It is a kind of separation equipment with novel structure, advanced technology, high efficiency and low consumption. The machine is widely used in petroleum, chemical, mining, pharmaceutical and other industries.

With the continuous improvement of the country’s environmental protection requirements, major oil fields are confronted with the problem of drilling waste disposal.

KOSUN’s VC-1000 series vertical cuttings dryer can be used for various types of drilling mud, mainly for oil-base and composite mud cuttings drying. Similar to other solid control equipment, such as vibrating screen, centrifuge, cyclone separator. The treatment ability of VC-1000 series vertical cuttings dryer also has a great relationship with mud viscosity. Mud viscosity is determined by many factors, including solids content, particle size, drilling fluid type and drilling fluid temperature.

Features and advantages of KOSUN’s VC-1000 series vertical cuttings dryer:

1. Efficient solid-liquid separation can minimize the mud content in drilling cuttings and reduce the amount of waste disposal;

2. Effective separation and a larger proportion of the recovery mud, and reuse in the mud circulation system, can recover the mud due to the vibration screen slurry, mobile derrick and screen blockage;

3. Common wear parts can be replaced from the top of the device, and the belt can be replaced without moving any device;

4. The scraper of inner rotating body is sprayed with tungsten carbide anti-corrosion and wear-resistant material, which can prolong its service life and reduce the maintenance cost.

Xi ‘an KOSUN’s main products of mud circulation system

Mud circulation system mainly includes by drilling fluid shale shaker, vacuum degasser, desander, desilter, sand mud removal machine, liquid gas separator, mixer, sand pump, shear pump, centrifuge, electronic ignition device, slurry mixing funnel, jet device, such as mud tank oil drilling mud solids control equipment and complete sets of circulatory system.

Xi ‘an KOSUN’s main products: drilling fluid shale shaker, vacuum degasser, mud cleaner, sand remover, mud remover, drilling fluid centrifuge, driller and other drilling mud solid control equipment, complete mud purification, recovery system and drilling mud treatment system.

Mud circulation system is suitable for mud circulation operation in oil well and water well drilling. Mud circulation system is also widely used in petroleum and gas exploration industry, trenchless engineering, geotechnical engineering, mining, metallurgy, coal, hydropower and other industries.

Functions and features of KOSUN mud circulation system:

1. The shell of the box is pressed and formed by steel plate, with beautiful appearance and high strength;

2. Modular and fast combination design, suitable for different types and specifications of drilling rig configuration requirements;

3. Complete mud treatment equipment combination, adapt to the mud treatment requirements of modern complex drilling technology;

4. Mud circulation system can be designed and configured according to user’s requirements.

Shear pump is one of the necessary pumps for drilling fluid treatment.

Shear pump is one of the necessary pumps for drilling fluid treatment. Used in solid – liquid separation system to improve drilling fluid performance.

1. The overall structure is compact and elegant;

2. Special impeller and shear plate are adopted, with shear efficiency greater than 95%;

3. The impeller and shear pump are made of stainless steel, and the flow parts are made of high wear resistant cast iron;

4. The use of mechanical seal mainly, pan root seal as a supplement of the combination of compound seal, mechanical seal using hard alloy, its service life is 6 times the ordinary mechanical seal.

The SP series shear pumps produced by xi ‘an KOSUN are specially used to shear the polymers of drilling fluid. The polymers in the drilling fluid system should be fully cut in advance and then enter the drilling fluid system to improve the performance of the drilling fluid.

SP series shear pump is a new type of equipment designed by KOSUN to provide customers with fast preparation and treatment of mud, which can meet the requirements of users to prepare high-performance mud. SP series shear pumps can mix effectively. It is an ideal drilling fluid solid control equipment, which can fully hydrate drilling fluid, save mud material, shorten mud preparation time, and provide good mud performance for drilling process.

Different from China, developed countries abroad have long realized that sludge treatment and disposal is an indispensable link in the process of sewage treatment.

Different from China, developed countries abroad have long realized that sludge treatment and disposal is an indispensable link in the process of sewage treatment. They have made clear provisions on the objectives of sludge treatment and disposal in terms of laws and policies, and ensured the implementation through a series of policies.

In sludge treatment of the United States, in addition to the treatment of generated sludge, the whole sewage treatment system and sludge treatment system are regarded as an organic whole. In sewage treatment, sludge co-treatment is realized. As early as 1998, the European Union legislated to ban the Marine discharge of sludge, and the sanitary landfill of sludge should be gradually banned. The annual sludge capacity of 50,000 sewage treatment plants in EU countries is 40 million tons, and more than 50% of the sludge has been treated with anaerobic digestion, among which the anaerobic digestibility of sludge in Britain reaches 66%.

It can be seen that policy and technology are still effective ways to improve China’s sewage treatment capacity. Technical methods: to further accelerate the localization of sludge treatment and disposal equipment, improve the management and operation level of sewage treatment plants. In terms of policy, effectively coordinate the management of sludge treatment and disposal involving multiple units; More binding mandatory sludge discharge standards; Actively support the development and application of new sludge treatment technology; To encourage investment in sludge treatment by water plants. 66%.
